Sample Questions

1.
A nurse needs to administer the prescribed fitness test to a client who has had prior cardiac-related symptoms. Which of the following fitness test methods is likely the most suitable for the client?
A)
Cross-trainer fitness test
B)
Maximal fitness test
C)
Ambulatory electrocardiogram
D)
Stress electrocardiogram
Ans:
C

Feedback:

An ambulatory electrocardiogram is used when the person has had prior cardiac-related symptoms, such as chest pain, or has major health risks that contraindicate a stress electrocardiogram. It is a less taxing version of a stress electrocardiogram. A stress electrocardiogram tests electrical conduction through the heart during maximal activity and is performed in an acute care facility or outpatient clinic. A cross-trainer fitness test is a normal fitness test done on a cross-trainer fitness machine. A maximal fitness test would tax the client to exhaustion and would be a safety risk.

2.
A nurse is assessing the body mass index of a client during a comprehensive assessment. Which of the following variables could the nurse include in a determination of the client’s body composition?
A)
Skin thickness
B)
Pulse rate
C)
Blood pressure
D)
Body temperature
Ans:
A

Feedback:

Factors that determine body composition include anthropometric measurements such as height, weight, body mass index, skinfold thickness, and mid-arm muscle circumference. Body composition is the amount of body tissue that is lean versus the amount that is fat. Pulse rate, blood pressure, and temperature do not determine body composition, but rather a person’s vital signs and physical status.

3.
A nurse is examining and documenting the physical condition of a client who is undergoing a prescribed stress electrocardiogram test at a health care facility. Which of the following observations should the nurse prioritize in an effort to ensure the test is performed safely?
A)
Client’s breathing pattern
B)
Client’s endurance level
C)
Client’s running speed
D)
Client’s muscle reflexes
Ans:
A

Feedback:

During a stress electrocardiogram test, the nurse or the examiner notes the client’s breathing pattern, heart rate and rhythm, blood pressure, and symptoms such as dizziness and chest pain. The client’s endurance level, running speed, and muscle reflexes are part of the maximal activity performed by the client during the test but these variables do not directly indicate difficulty with completing the test or the presence of unintended health consequences.

4.
A client is wearing a Holter monitor in order to undergo a prescribed ambulatory electrocardiogram. Which of the following precautions should the client take during an ambulatory electrocardiography test?
A)
Insulate all metal detectors.
B)
Avoid taking sponge baths.
C)
Avoid showering or swimming.
D)
Use an electric blanket rather than heavy cloth blankets.
Ans:
C

Feedback:

During a prescribed ambulatory electrocardiography test, the client should not shower or swim; a sponge bath is permitted as long as the monitor does not get wet. The client also should avoid magnets, metal detectors, electric blankets, and high-voltage areas that may cause artifacts on the recordings that interfere with an accurate interpretation of the test results.

5.
A client has been ordered to undergo a step test. Which of the following arrangements is of greatest importance during a step test?
A)
Reduce the height of the step test machine platform.
B)
Make arrangements for a metronome and a stopwatch.
C)
Shorten the test time when the client’s heart rate is rapid.
D)
Make provisions for possible cardiopulmonary resuscitation.
Ans:
D

Feedback:

The most important arrangement that a nurse should make during a step test is to ask for the assistance of personnel certified in cardiopulmonary resuscitation and the use of an automatic cardiac defibrillator if there is an adverse cardiac event. The step test is used with caution; hence, test time is shortened if the client develops discomfort. The examiner uses a metronome and a stopwatch to keep track of the rate and the time, but this is not the most important arrangement. The height of the step test machine platform is prescribed as per the client.
