Question 1

The nurse is providing an educational session for a group of preschool workers.The nurse reminds the group that the most important thing to do to prevent the spread of infection is to
A) Encourage preschool children to eat a nutritious diet.
B) Encourage parents to provide a multivitamin to the children.
C) Clean the toys every afternoon before putting them away.
D) Wash their hands between each interaction with children.

Accepted Answer

The single most important thing that individuals can do to prevent the spread of infection is to wash their hands before and after eating,going to the bathroom,changing a diaper,and wiping a nose,as well as after cleaning toys or tables,after picking up after the children,and between touching each individual child.It is important for preschool children to have a nutritious diet; a healthy individual can fight infection more effectively.A physician,along with the parent,makes decisions about dietary supplements.Cleaning the toys can decrease the number of pathogens but is not the most important thing to do in this scenario.

Question 2

A diabetic patient presents to the clinic for a dressing change.The wound is located on the right foot and has purulent yellow drainage.Which of these interventions would be most appropriate for the nurse to provide?
A) Position the patient comfortably on the stretcher.
B) Explain the procedure for dressing change to the patient.
C) Don gloves and other appropriate personal protective equipment.
D) Review the medication list that the patient brought from home.

Accepted Answer

Localized infections are most common in the skin or with mucous membrane breakdown.Wear gloves and other personal protective equipment as appropriate when examining or providing treatment to localized infected areas.Positioning the patient,explaining the procedure,and reviewing the medication list are all tasks that need to be completed,but preventing the spread of infection takes precedence.

Question 3

Which of the following nursing actions would most increase a patient's risk for developing a health care-associated infection?
A) Use of surgical aseptic technique to suction an airway
B) Urinary catheter drainage bag placed below the level of the bladder
C) Clean technique for inserting a urinary catheter
D) Use of a sterile bottled solution more than once within a 24-hour period

Accepted Answer

Using clean technique (medical asepsis)to insert a urinary catheter would place the patient at risk for a health care-associated infection.Urinary catheters need to be inserted using sterile technique,also referred to as surgical asepsis.This involves eliminating all microorganisms,including pathogens and spores,from an object or area.Placing a catheter into a sterile body cavity such as the bladder requires sterile technique.Surgical aseptic technique (also called sterile technique)should be used when suctioning an airway because it is considered a sterile body cavity.Keeping the urinary catheter drainage bag below the bladder helps decrease the risk of developing a health care-associated infection because it prevents reflux of urine from the bag back into the bladder.Bottled solutions may be used repeatedly during a 24-hour period; however,special care is needed to ensure that the solution in the bottle remains sterile.After 24 hours,the solution should be discarded.

Question 4

The patient and the nurse are discussing Rickettsia rickettsii-Rocky Mountain spotted fever.Which patient statement to the nurse indicates understanding regarding the mode of transmission of this disease?
A) "When I go camping, I will be sure to wear sunscreen."
B) "When I go camping, I will drink bottled water."
C) "When I go camping, I will be sure to wear insect repellent."
D) "When I go camping, I will be sure to use hand gel on my hands."

Accepted Answer

Each infectious disease has a specific mode of transmission-a component of the chain of infection.Rocky Mountain spotted fever is caused by bacteria transmitted by the bite of ticks.Wearing a repellent that is designed for repelling ticks,mosquitoes,and other insects can help in preventing transmission of this disease.Drinking plenty of uncontaminated water,wearing sunscreen,and using alcohol-based hand gels for cleaning hands are all important activities to participate in while camping,but they do not contribute to or prevent transmission of this disease.

Question 5

The nurse is caring for a patient with leukemia and is preparing to provide fluids through a vascular access device.Which nursing intervention is priority in this procedure?
A) Position the patient comfortably.
B) Maintain aseptic technique.
C) Gather available supplies.
D) Review the procedure with the patient.

Accepted Answer

Patients with disease processes of the immune system are at particular risk for infection.These diseases include leukemia,AIDS,lymphoma,and aplastic anemia.These disease processes weaken the defenses against an infectious organism.It is priority that anytime an intravenous device is accessed,aseptic technique must be maintained with wearing of appropriate personal protective equipment,preparation of the skin,and use of sterile gloves,sterile supplies,appropriate flushing,and appropriate discontinuation.Reviewing the procedure with the patient,positioning the patient,and gathering the supplies are all important steps in the procedure but are not the priority in the procedure.

Question 6

The infection control nurse is reviewing data for the medical-surgical unit.The nurse notices a spike in postoperative infections on this unit and categorizes this type of health care-associated infection as _____ infections.
A) Iatrogenic
B) Exogenous
C) Endogenous
D) Nosocomial

Accepted Answer

An exogenous organism is one that is present outside the patient.A postoperative infection is an exogenous infection because the organism that has caused the infection presents from outside the body.An example is Staphylococcus aureus.An endogenous organism is part of the normal flora of residing virulent organisms that could cause infection.An endogenous infection can occur when part of the patient's flora becomes altered,and overgrowth results.Iatrogenic infection results from a diagnostic or therapeutic procedure such as a colonoscopy.Nosocomial infection is the term formerly used for health care-acquired infection.

Question 7

The nurse is caring for a patient in labor and delivery.When near completing an assessment of the patient for dilatation and effacement,the electronic infusion device being used on the intravenous infusion alarms.Which of these actions is most appropriate for the nurse to take?
A) Complete the assessment, remove gloves, and silence the alarm.
B) Discontinue the assessment, and assess the intravenous infusion.
C) Complete the assessment, remove gloves, wash hands, and assess the intravenous infusion.
D) Discontinue the assessment, remove gloves, use hand gel, and assess the intravenous infusion.

Accepted Answer

Medical asepsis or clean technique includes procedures to decrease the number of organisms present and to prevent the transfer of organisms.Wearing gloves while assessing the dilatation and effacement of a labor and delivery patient,removing gloves,washing hands after contact with body fluids,and then assessing the intravenous infusion will assist in the prevention and transfer of any potential organisms to this intravenous line.Completing the assessment,removing gloves,and silencing the alarm leaves out the crucial step of decontaminating and washing the hands.Discontinuing the assessment and assessing the IV leaves out removing the gloves and decontamination,as well as completing the assessment for the patient.Discontinuing the assessment,removing gloves,using hand gel,and assessing the IV is incorrect because upon exposure to body fluids,washing hands is appropriate.

Question 8

A female adult patient presents to the clinic with reports of a white discharge and itching in the vaginal area.During the health history,which of these questions should the nurse prioritize?
A) "When was the last time you visited the physician?"
B) "Has this condition affected your eating habits?"
C) "What medications are you currently taking?"
D) "Are you able to sleep at night?"

Accepted Answer

The body contains normal flora (microorganisms)that live on the surface of skin,saliva,oral mucosa,gastrointestinal tract,and genitourinary tract.The normal flora of the vagina causes vaginal secretions to achieve a low pH.This inhibits the growth of many microorganisms.Antibiotics and oral contraceptives can disrupt normal flora in the vagina,causing an overgrowth of Candida albicans in that area.It is important to ask the patient about current medications to obtain information that may assist with diagnosis.Visiting the physician is important for the patient's health maintenance.Learning about the patient's eating and sleeping habits will assist in the plan of care.

Question 9

The nurse is caring for a group of medical-surgical patients.The patient most at risk for developing an infection is the patient who
A) Is in observation for chest pain.
B) Is recovering from a right total hip arthroplasty.
C) Has been admitted with dehydration.
D) Has been admitted for stabilization of atrial fibrillation.

Accepted Answer

The patient who is recovering from a right total hip arthroplasty has had a surgical procedure wherein bone was removed from the body and an implant was placed within the patient.The patient has a large incision from surgery.The patient also has an intravenous infusion to provide fluids and medication.All these breaks in the skin increase the likelihood of infection.The patient has had anesthesia and medication for pain.Both of these depress the respiratory system and have the potential to decrease the expansion of alveoli and to increase the chance of infection in the respiratory system.The other patients may have one break in the skin when an intravenous infusion is used.

Question 10

The patient has contracted a urinary tract infection while in the hospital.Which of these actions would most likely increase the risk of a patient contracting a urinary tract infection (UTI)?
A) Emptying the urinary drainage bag once a shift
B) Reusing the patient's graduated receptacle to empty the drainage bag
C) Allowing the drainage bag port to touch the graduated receptacle
D) Providing perineal hygiene at least once a shift

Accepted Answer

Allowing the urinary drainage bag port to touch contaminated items may introduce bacteria into the system and contribute to a urinary tract infection.The urinary drainage bag should be emptied at least once every 8 hours.Each patient should have his own receptacle for measurement to prevent cross-contamination.Perineal hygiene should be provided every 8 hours and after bowel movements to assist in preventing a UTI.

Question 11

The nurse is caring for a school-aged child who has injured his leg after a bicycle accident.To determine whether the child is experiencing a localized inflammatory response,the nurse should assess for which of these signs and symptoms?
A) Fever, malaise, anorexia, and nausea and vomiting
B) Chest pain, shortness of breath, and nausea and vomiting
C) Dizziness and disorientation to time, date, and place
D) Edema, redness, tenderness, and loss of function

Accepted Answer

The body's cellular response to an injury is seen as inflammation.Inflammation can be triggered by physical agents,chemical agents,or microorganisms.Signs of localized inflammation include swelling,redness,heat,pain or tenderness,and loss of function in the affected body part.Systemic signs of inflammation include fever,malaise,and anorexia,as well as nausea and vomiting.Chest pain,shortness of breath,and nausea and vomiting are signs and symptoms of a cardiac alteration.Dizziness and disorientation to time,date,and place may indicate a neurologic alteration.

Question 12

The nurse is admitting a patient with an infectious disease process.What question would be appropriate for a nurse to ask this patient?
A) "Do you have a chronic disease, and how long have you had it?"
B) "Do you have any children living in the home?"
C) "What is your marital status-single, married, or divorced?"
D) "Do you have any cultural or religious beliefs that will influence your care?"

Accepted Answer

Some factors increase the susceptibility of an individual to acquire an infection.These include age,nutritional status,presence of chronic disease,trauma,and smoking.The other questions are part of an admission assessment process but are not pertinent to the infectious disease process.

Question 13

Which of these interventions would take priority and should be included in a plan of care for a patient who presents with pneumonia?
A) Observe the patient for decreased activity tolerance.
B) Assume that the patient is in pain and treat accordingly.
C) Maintain the temperature at 65° F.
D) Provide the patient ice chips as requested.

Accepted Answer

Systemic infection causes more generalized symptoms than local infection.This type of infection can result in fever,fatigue,nausea and vomiting,and malaise.Be alert for changes in the patient's level of activity and responsiveness.Respiratory infection may result in a productive cough with purulent sputum,shortness of breath,and activity intolerance.Nurses do not assume but assess and communicate with the patient about pain,temperature,and ice chips.Asking these questions would not be a priority as much as assessing the patient and determining the effect that the systemic infection is having on the patient.

Question 14

The nurse is caring for a patient who is susceptible to infection.Which of the following nursing interventions will assist in decreasing the risk of infection?
A) Teaching the patient about fall prevention
B) Teaching the patient to select nutritious foods
C) Teaching the patient to take a temperature
D) Teaching the patient about the effects of alcohol

Accepted Answer

When protein intake is inadequate as a result of poor diet,the rate of protein breakdown exceeds that of tissue synthesis.A reduction in the intake of protein and other nutrients such as carbohydrates and fats reduces the body's defenses against infection and impairs wound healing.Teaching the patient about fall prevention,how to take a temperature,or about the effects of alcohol does not decrease the risk of infection.

Question 15

The patient experienced a surgical procedure,and Betadine was utilized as the surgical prep.Two days postoperatively,the nurse's assessment indicates that the incision is red and has a small amount of purulent drainage.The patient reports tenderness at the incision site.The patient's temperature is 100.5° F and the WBC is 10,500/mm³.Which nursing action should the nurse take?
A) Plan to change the surgical dressing during the shift.
B) Check to see what solution was used for skin preparation in surgery.
C) Collect supplies to culture the surgical incision.
D) Utilize SBAR to call and communicate the patient's needs to the physician.

Accepted Answer

Organisms enter the body in several different ways.Proper skin preparation for surgery is essential to decrease the chance of infection.The nursing assessment indicates signs and symptoms of infection.The physician needs to be called and notified of the patient's needs.SBAR-Situation,Background,Assessment,and Recommendation-can be utilized to organize thoughts and data and to provide a through explanation of the patient's current status.Changing the dressing may be a need during the shift but is not a first priority.Checking to see about the skin prep used 2 days ago may or may not be useful information at this time.Collecting supplies for culture may be necessary after talking with the physician.

Question 16

The nurse is inserting a peripherally inserted central catheter (PICC)into the patient.Aware of the potential for health care-associated infection,the nurse is careful to
A) Prepare the skin with 2% chlorhexidine gluconate.
B) Select a catheter of appropriate size for the appropriate vein.
C) Use nonallergenic tape and dressings on the patient.
D) Utilize local anesthetic on the site as ordered.

Accepted Answer

One of the sites for health care-associated infection is the bloodstream.Bloodstream infection can be caused by improper care of the needle insertion site.Two percent chlorhexidine gluconate is an antiseptic solution that when applied properly and allowed to dry reduces microbial counts at the insertion site.Selecting the correct catheter size,using nonallergenic tape and dressings,and utilizing local anesthetic are important steps for individualized patient care and are typically part of the procedure,but they do not affect the cause of a health care-associated infection by,for example,decreasing microbial counts at the insertion site.

Question 17

Which interventions utilized by the nurse would indicate the ability to recognize the inflammatory response?
A) Rest, ice, compression, and elevation
B) Turn, cough, and deep breathe
C) Orient to date, time, and place
D) Passive range-of-motion exercises

Accepted Answer

One sign of the inflammatory response,particularly after an injury,is swelling or edema.Resting the affected injured area,using ice as ordered,wrapping the area to provide support-particularly if it is an extremity-and elevating the injured area will help to decrease swelling or edema.Turn,cough,and deep breathe is utilized for postoperative patients and for immobilized patients to help prevent an infectious process such as pneumonia.Orientation to date,time,and place is an intervention utilized with many different types of patients who may be confused.Passive range of motion is utilized for individuals who need to improve movement of their extremities,including immobilized patients.

Question 18

The nurse is caring for a patient with pneumonia with a new nurse in orientation.Which of the following statements by the new nurse would indicate an understanding of the nature of this condition?
A) "An infectious disease like pneumonia may not pose a risk to others."
B) "We need to isolate the patient in a negative pressure room."
C) "The patient will not be able to return home."
D) "Clinical signs and symptoms are not present in pneumonia."

Accepted Answer

Infections are infectious or communicable.Infectious diseases may not pose a risk for transmission to others,although they are serious for the patient.Pneumonia is not a communicable disease-a disease that is transmitted directly from one individual to the next; so there is no need for isolation.Clinical signs and symptoms are present in pneumonia and include but are not limited to elevated temperature,shortness of breath,fatigue,and coughing; in addition,the patient may have rhonchi and crackles upon auscultation.Frequently,patients with pneumonia do return home unless there are extenuating circumstances.

Question 19

The nurse is caring for an adult patient in the clinic who has been evacuated and is a victim of flooding.The patient presents with signs and symptoms of a urinary tract infection.Along with needed education surrounding this diagnosis,the nurse teaches the patient about rest,exercise,eating properly,and how to utilize deep breathing and visualization.Which of these explanations would best support these nursing interventions?
A) Urinary tract infections are painful, and these techniques would help with managing the pain.
B) Interventions listed are standard topics taught during health care visits.
C) Stress for long periods of time can lead to exhaustion and decreased resistance to infection.
D) The patient requested this information to teach to extended family at home.

Accepted Answer

The body responds to emotional or physical stress by the general adaptation syndrome.If stress extends for long periods of time,this can lead to exhaustion,whereby energy stores are depleted and the body has no defenses against invading organisms.Techniques of deep breathing and visualization may be helpful with pain,but the interventions listed are not all standard interventions taught at every health care visit.

Question 20

The nurse is providing an education session to an adult community group about the effects of smoking.Which of the following is the most important point to be included in the educational session?
A) Smoke from tobacco products clings to your clothing and hair.
B) Smoking affects the cilia lining the upper airways in the lungs.
C) Smoking tobacco products can be very expensive.
D) Smoking can affect the color of the patient's fingernails.

Accepted Answer

A normal defense mechanism against infection in the respiratory tract is the cilia lining the upper airways of the lungs and normal mucus.When a patient inhales a microbe,the cilia and mucus trap the microbe and sweep them up and out to be expectorated or swallowed.Smoking may alter this defense mechanism and increase the patient's potential for infection.Smoking can be expensive,the smell does cling to hair and clothing,and the tar within the smoke can alter the color of a patient's nails.This information can be included in the education but does not constitute the most important point.
