Question 1

The patient has contracted a urinary tract infection (UTI) while in the hospital. Which action will $\bold{most}$ likely increase the risk of a patient contracting a UTI?

Accepted Answer

Allowing the urinary drainage bag port to touch contaminated items (graduated receptacle) may introduce bacteria into the urinary system and contribute to a urinary tract infection. The urinary drainage bag should be emptied at least once a shift. Patients should have their own receptacle for measurement to prevent cross-contamination. Repeated catheter irrigations increase the chance so irrigating infrequently will be beneficial in reducing the risk.

Question 2

Which nursing action will most likely increase a patient's risk for developing a health care-associated infection?

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, which is also referred to as surgical asepsis. Surgical aseptic technique (also called sterile technique) should be used when suctioning an airway because it is considered a sterile body cavity. Washing from clean to dirty (urinary meatus toward rectum) is correct for decreasing infection risk. 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 3

The nurse is caring for a school-aged child who has injured the right leg after a bicycle accident. Which signs and symptoms will the nurse assess for to determine if the child is experiencing a localized inflammatory response?

Accepted Answer

The body's cellular response to an injury is seen as inflammation. 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 enlarged lymph nodes and increased white blood cells. 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 4

The nurse is caring for a patient in an intensive care unit who needs a bath. Which priority action will the nurse take to decrease the potential for a health care-associated infection?

Accepted Answer

The Centers for Disease Control and Prevention (CDC) recommends the use of chlorhexidine (CHG) bathing for patients in intensive care units, patients who are scheduled for surgery, and all patients with invasive central line catheters as part of MRSA reduction efforts. Using local anesthetics, nonallergenic tape, and filtered water does not affect the cause of a health care-associated infection by, for example, decreasing microbial counts like a CHG bath.

Question 5

The nurse is caring for a patient who is susceptible to infection. Which instruction will the nurse include in an educational session to decrease the risk of infection?

Accepted Answer

A patient's nutritional health directly influences susceptibility to infection. A reduction in the intake of protein and other nutrients such as carbohydrates and fats reduces body defenses against infection and impairs wound healing. This is the only teaching point that directly influences risk. Teaching the patient how to take a temperature can help the patient assess if there is a fever, but it is not related to decreasing the individual's risk for infection. Teaching the patient about fall prevention or about the effects of alcohol does not decrease the risk of infection.

Question 6

The nurse is caring for a patient in labor and delivery. When near completing an assessment of the patient's cervix, the electronic infusion device being used on the intravenous (IV) infusion alarms. Which sequence of actions is most appropriate for the nurse to take?

Accepted Answer

Completing the assessment while wearing gloves, 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 7

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 action should the nurse take first?

Accepted Answer

The nursing assessment indicates signs and symptoms of infection, requiring the primary health care provider to be notified of the patient's needs. SBAR-Situation, Background, Assessment, and Recommendation-can be utilized to organize thoughts and data and to provide a thorough explanation of the patient's current status. The reevaluation of temperature is a good choice, but it will take longer than 4 hours to make a change in the white blood cells. Changing the dressing may be a need during the shift but is not a first priority. Checking to see about the skin preparation used 2 days ago may or may not be useful information at this time.

Question 8

The infection control nurse is reviewing data for the medical-surgical unit. The nurse notices an increase in postoperative infections from Aspergillus. Which type of health care-associated infection will the nurse report?

Accepted Answer

An exogenous infection comes from microorganisms found outside the individual such as Salmonella, Clostridium tetani, and Aspergillus. They do not exist as normal floras. A vector transmits microorganisms and is usually a type of insect or organism. Endogenous infection occurs when part of the patient's flora becomes altered and an overgrowth results (e.g., staphylococci, enterococci, yeasts, and streptococci). This often happens when a patient receives broad-spectrum antibiotics that alter the normal floras. A suprainfection develops when broad-spectrum antibiotics eliminate a wide range of normal flora organisms, not just those causing infection.

Question 9

The nurse is providing an educational session for a group of preschool workers. The nurse reminds the group about the $\bold{most}$ important thing to do to prevent the spread of infection. Which information did the nurse share with the preschool workers?

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 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 health care provider, 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 10

A female adult patient presents to the clinic with reports of a white discharge and itching in the vaginal area. A nurse is taking a health history. Which question is the priority?

Accepted Answer

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. 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, inhibiting the growth of many microorganisms. Visiting the primary health care provider is important for the patient's health maintenance but is not the priority. Learning about the patient's eating and sleeping habits will assist in the plan of care but is not the priority.

Question 11

The nurse is caring for a patient with leukemia and is preparing to provide fluids through a vascular access (IV) device. Which nursing intervention is a priority in this procedure?

Accepted Answer

You maintain surgical aseptic technique at the patient's bedside (e.g., when inserting IV or urinary catheters, suctioning the tracheobronchial airway, and sterile dressing changes) because 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. 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 since the patient already has a compromised immune response.

Question 12

Which interventions utilized by the nurse will indicate the ability to recognize a localized inflammatory response?

Accepted Answer

Signs of localized inflammation include swelling, redness, heat, pain or tenderness, and loss of function in the affected body part. 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. Turning, coughing, and deep breathing are 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. Vigorous range of motion would irritate the inflammatory process. Range of motion is utilized for individuals who need to improve movement of their extremities, including immobilized patients.

Question 13

The nurse is caring for a group of medical-surgical patients. Which patient is most at risk for developing an infection?

Accepted Answer

The patient who is recovering from a right total hip surgery has a large incision from the surgery. This break in the skin increases the likelihood of infection. Any break in the integrity of the skin and mucous membranes allows pathogens to enter and exit the body. The patient has had anesthesia, which depresses the respiratory system and has the potential to decrease the expansion of alveoli and to increase the chance of infection in the respiratory system. A patient who is having chest pain, experiencing dehydration, or being admitted with heart problems does not have open incisions that break the skin; therefore, his or her infection risk is lower.

Question 14

The nurse and a new nurse in orientation are caring for a patient with pneumonia. Which statement by the new nurse will indicate a correct understanding of this condition?

Accepted Answer

Infections are infectious and/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. A private negative-air pressure room is used for tuberculosis, not pneumonia. Clinical signs and symptoms are present in pneumonia. Frequently, patients with pneumonia do return home unless there are extenuating circumstances.

Question 15

The nurse is providing an education session to an adult community group about the effects of smoking on infection. Which information is most important for the nurse to include in the educational session?

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.

Question 16

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 for this disease?

Accepted Answer

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 17

The nurse is admitting a patient with an infectious disease process. Which question will be most appropriate for a nurse to ask about the patient's susceptibility to this infectious process?

Accepted Answer

Multiple factors influence a patient's susceptibility to infection. Patients with chronic diseases such as diabetes mellitus and multiple sclerosis are also more susceptible to infection because of general debilitation and nutritional impairment. Other factors include age, nutritional status, trauma, and smoking. The other questions are part of an admission assessment process but are not pertinent to the infectious disease process.

Question 18

A patient presents with pneumonia. Which priority intervention should be included in the plan of care for this patient?

Accepted Answer

Systemic infection, like pneumonia, 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. Nurses do not assume but assess and communicate with the patient about pain. While providing the patient with ice chips may be appropriate, it is not a priority and there is no reason for the patient to be limited to ice. Maintaining the room temperature at 65° F is too cold.

Question 19

The nurse is caring for an adult patient in the clinic who has been evacuated and is a victim of flooding. The nurse teaches the patient about rest, exercise, and eating properly and how to utilize deep breathing and visualization. What is the primary rationale for the nurse's actions related to the teaching?

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 they are not the primary reason. The teachings listed are not all standard interventions taught at every health care visit. There is no data to indicate the patient requested this information for the family.

Question 20

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 action will the nurse take to prevent the spread of infection?

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 to create a protective barrier. Positioning the patient, explaining the procedure, and reviewing the medication list are all tasks that need to be completed, but they do not prevent the spread of infection.

Quiz 29: Infection Prevention and Control

The patient has contracted a urinary tract infection (UTI) while in the hospital. Which action will most\bold{most}most likely increase the risk of a patient contracting a UTI?
