Question 1

The nurse records the EKG of an asymptomatic patient. Which of the following EKG findings confirms the diagnosis of Wenckebach phenomena?&#10;A)No definite relation between P-wave and QRS complex&#10;B)Progressive lengthening of PR interval followed by a P wave without an associated QRS complex&#10;C)Prolonged PR interval with narrow QRS complex&#10;D)Prolonged PR interval with wide QRS complex

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?&#10;A)Electrocardiogram, echocardiography, chest x-ray&#10;B)Electrocardiogram, stress echocardiography, chest CT&#10;C)Electrocardiogram, transthoracic echocardiography, ambulatory blood pressure monitoring&#10;D)Electrocardiogram, holter monitoring, thallium scan

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?&#10;A)No relationship between p-wave and QRS complex&#10;B)Progressive lengthening of PR interval followed by a p wave without an associated QRS complex&#10;C)Prolonged PR interval with narrow QRS complex&#10;D)Prolonged PR interval with wide QRS complex

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:&#10;A)Guidelines designed to prevent transmission of infection from any source of body fluid, except sweat, in healthcare settings.&#10;B)Guidelines designed to prevent transmission of infection by blood and body fluids in healthcare settings.&#10;C)Guidelines designed to prevent transmission of infection by a known source of infection.

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?&#10;A)A route of pathogenic transmission, from one host to another.&#10;B)A method of transmitting information.&#10;C)The categories of isolation.

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?&#10;A)Hazard Communication Standard.&#10;B)Standard Precautions.&#10;C)Needle Safety Act.

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

&#34;All equipment that contains needles must have a system to single-handedly permanently resheath the needle.&#34; 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?

A)Yellow indicates a reactivity/stability hazard. The number 4 indicates no hazard.
B)Yellow indicates a reactivity/stability hazard. The number 4 indicates extreme hazard.
C)Yellow indicates a special hazard. The number 4 indicates a moderate hazard.
D)Yellow indicates a flammability hazard. The number 4 indicates a mild hazard.

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?&#10;A)A mild flammability hazard.&#10;B)A moderate flammability hazard.&#10;C)A mild blood borne hazard.&#10;D)A moderate blood borne hazard.

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).
