Question 1

The nurse records the EKG of an asymptomatic patient. Which of the following EKG findings confirms the diagnosis of Wenckebach phenomena?

Accepted Answer

The EKG finding of progressive lengthening of PR interval followed by a P wave without an associated QRS complex confirms the diagnosis of Wenckebach phenomena. Second-degree atrioventricular block type I, also known as Wenckebach or Mobitz I, is an asymptomatic dysrhythmia typically diagnosed on electrocardiogram which shows progressive lengthening of PR interval followed by a P wave without an associated QRS complex.

Question 2

Which of the following diagnostic tests should be done for a patient who wants to be screened for presence of valvular heart disease?

Accepted Answer

Electrocardiogram, echocardiography and chest x-ray should be done to screen a patient for presence of valvular heart disease. Diagnostic tools used to screening for valvular diseases include electrocardiogram, echocardiography, magnetic resonance imaging, and chest x-ray. Other diagnostic tests to rule out any other co-morbid cardiovascular conditions include cardiac stress testing and cardiac catheterization.

Question 3

Which of the following sentences correctly describes the EKG findings of Wenckebach phenomena?

Accepted Answer

Second-degree atrioventricular block type I, also known as Wenckebach or Mobitz I, is an asymptomatic dysrhythmia typically diagnosed on electrocardiogram which shows progressive lengthening of PR interval followed by a p wave without an associated QRS complex.

Question 4

Transmission-based Precautions are:

Accepted Answer

Transmission-based precautions are guidelines designed to prevent transmission of infection when the source of infection is known or suspected. These guidelines are used in addition to Standard Precautions and are categorized by mode of transmission, air-borne, droplet, or contact.

Question 5

Is a splash-proof face shield necessary to enter a contact isolation room?

Accepted Answer

A splash-proof face shield is not necessary to enter a contact isolation room. Splash-proof face shields are usually used when exposure to splashing of body fluids or substances is anticipated.

Question 6

Which of the following defines mode of transmission?

Accepted Answer

The mode of transmission is the route a pathogen requires for transmission from one host to another. There are five modes of transmission: Contact, Droplet, Airborne, Vehicle (pathogen is carried in contaminated substance such as earth, food, or water), Vector (pathogen is carried by insects and animals).

Question 7

A properly labeled chemical container, is an example of compliance with which OSHA standard?

Accepted Answer

Properly labeled chemical containers are an example of compliance with the Hazard Communication Standard. This standard requires awareness of all workers of the chemicals being used in the workplace.

Question 8

"All equipment that contains needles must have a system to single-handedly permanently resheath the needle." Is the above a federal requirement of healthcare employers?

Accepted Answer

The Safety Needle Act requires healthcare employers to provide needle-containing equipment that permanently resheath the needle by a single-handed method.
Currently, the primary legislation covering sharps safety is the 1999-2000 Needlestick Safety and Prevention Act. This landmark legislation updated the Office of Safety And Health Administration (OSHA) guidelines, compelling employers to use work practice controls and safer needle devices that are engineered to eliminate or minimize exposure to bloodborne pathogens resulting from needlestick injuries.
As a result of the act, employers must:
Demonstrate that they are reviewing new technology that can reduce the risk of exposure to bloodborne pathogens by updating exposure control plans and documenting the decision-making process on implementing such technology.
Maintain a sharps injury log to track the type and brand of device used, the department or area where the incident occurred, and an explanation of the incident. The log must be maintained in a manner to protect the confidentiality of the injured employee.
Solicit input from employees responsible for direct patient care in the identification, evaluation, and selection of effective safety devices and work practice controls, as part of the ongoing exposure control plan development process. Efforts to encourage staff input must be documented in the plan.

Question 9

In the hazard identification system, four small color-coded diamonds are grouped into a larger diamond. Numbers represent the severity of the hazard. What would the yellow diamond with the number 4 indicate?

Accepted Answer

Yellow indicates a reactivity/stability hazard. These are chemicals or substances capable of exploding or toxic chemical reactions. The number system is coded as zero (no hazard) through four (most hazardous). In the example, the yellow diamond with a number 4 indicates an extreme reactivity/stability hazard.

Question 10

What does a hazard identification label with a red diamond and the number 1 indicate?

Accepted Answer

A red diamond with a number 1 is part of the hazard identification system and indicates a mild flammability hazard. The blue diamond indicates health hazards. The white diamond is to indicate special health hazards such as radioactivity, special biohazards, and other dangerous-to-health elements. The yellow diamond indicates reactivity/stability hazards. The numbers indicate the severity of the hazard from none at all (0) to extremely hazardous (4).

Question 11

Hepatitis is:

Accepted Answer

Hepatitis is a liver infection that is caused by a virus. The hepatitis virus can be one of several different serotypes and can lead to cirrhosis or cancer of the liver in susceptible patients. Hepatitis B is a form of this disease that can be prevented by a series of three vaccines. Health care workers are offered this injection series free of change. Hepatitis A is a form of the disease that is acquired through contaminated food.

Question 12

Which of the following statements is true concerning HIV?

Accepted Answer

HIV is a blood-borne pathogen that can be spread through blood and body fluids. HIV can also be spread through sexual contact. HIV is a virus that can lead to the disease state known as AIDS. Health care workers are at risk for contracting HIV through needle-sticks or sharps-related injuries. HIV is not as virulent at Hepatitis.

Question 13

Asepsis procedures are necessary because:

Accepted Answer

Asepsis procedures reduce the spread of disease-causing organisms. Asepsis procedures require adequate cleaning of patient care areas, proper disinfection techniques prior to specimen collection, and sanitization and disinfection of reusable patient instruments. Asepsis is a medical term meaning, "without infection."

Question 14

Needle-stick protection devices are:

Accepted Answer

Needle-stick protection devices are required by law according to the Occupational Safety and Health Administration. These devices are engineering controls that reduce the risk of needle-sticks by providing a cover for used needles. Some devices are retractable needles, while others are safety caps that can be snapped on the needle after use. While all used needles should be placed directly into an approved sharps container, these engineering controls add an extra protective mechanism to avoid injury.

Question 15

A client has been identified as having a very virulent bacterial infection that is spread through close physical contact. The patient care technician understands that, in order to decrease the chance of spreading these organisms, which of the following infection control precautions should be observed?

Accepted Answer

For infections spread by direct contact with infected items, the nursing staff would implement contact precautions. All other precautions listed are not necessary. Standard precaution, which is not listed as an option, would also be used.

Question 16

The physician requests a pair of sterile scissors. A pair of scissors found at the bedside is in an original factory wrapping that has been opened but taped closed again. Which of the following should the patient care technician do?

Accepted Answer

The patient care technician should obtain a pair of sterile scissors that have not been opened. Using the principle of sterile technique, sterile objects once opened are considered unsterile because of the break in the sterile packaging. The exposure allows airborne microorganisms to infiltrate the sterile object. If you are in doubt about the sterility of the object, assume the object is unsterile

Question 17

A client has been identified as having a very virulent bacterial infection that is spread through close physical contact. The patient care technician understands that, in order to decrease the chance of spreading these organisms, which of the following infection control precautions should be observed?

Accepted Answer

For infections spread by direct contact with infected items, the nursing staff would implement contact precautions. All other precautions listed are not necessary. Standard precaution, which is not listed as an option, would also be used.

Question 18

Accepted Answer

The patient care technician should obtain a pair of sterile scissors that have not been opened. Using the principle of sterile technique, sterile objects once opened are considered unsterile because of the break in the sterile packaging. The exposure allows airborne microorganisms to infiltrate the sterile object. If you are in doubt about the sterility of the object, assume the object is unsterile

Question 19

After emptying urine from the bedpan of a client whose urinary output is being monitored, what should you do next?

Accepted Answer

After any procedure is completed, the patient care technician must wash her hands to prevent transmission of microorganism. The application of gloves is only necessary if the patient care technician must attend to another item of personal care before documenting urinary output; even so, hands should be washed first. Crucial information is reported to the nurse, not routine intake and output.
