1. Which of the following is considered the ‘fifth vital sign’ in clinical practice?
A. Oxygen Saturation
B. Blood Glucose
C. Pain Level
D. Height and Weight
Answer: C
Rationale: Pain level is often referred to as the fifth vital sign and should be assessed every
time other vital signs are measured.
2. When measuring an oral temperature, what is the normal range for an adult?
A. 96.6°F to 98.6°F
B. 95.0°F to 97.0°F
C. 98.6°F to 100.6°F
D. 97.6°F to 99.6°F
Answer: D
Rationale: The standard normal range for an oral temperature in adults is approximately
97.6°F to 99.6°F.
3. Which pulse site is most commonly used for routine vital sign checks?
A. Carotid
B. Radial
C. Brachial
D. Apical
Answer: B
,Rationale: The radial pulse, located on the thumb side of the wrist, is the most common
site for routine pulse measurement.
4. What is the medical term for a heart rate faster than 100 beats per minute?
A. Bradycardia
B. Arhythmia
C. Tachycardia
D. Hypertension
Answer: C
Rationale: Tachycardia is defined as a heart rate greater than 100 beats per minute in an
adult.
5. A resident has just finished drinking a cup of hot tea. How long should the
LNA wait before taking an oral temperature?
A. 5 minutes
B. 30 to 45 minutes
C. 10 to 20 minutes
D. No wait is necessary
Answer: C
Rationale: Drinking hot or cold liquids, smoking, or eating can affect oral temperature;

A. Axillary
B. Rectal
C. Oral
D. Tympanic
Answer: B

7. When counting respirations, the LNA should:
A. Tell the resident to breathe deeply
B. Keep fingers on the radial pulse so the resident doesn’t know they are being counted
C. Count for 5 seconds and multiply by 12
D. Count only the exhales
Answer: B

monitored, so keeping fingers on the pulse disguises the count.
8. What is the normal respiratory rate for a healthy adult at rest?
A. 8 to 12 breaths per minute
B. 20 to 30 breaths per minute
C. 12 to 20 breaths per minute
D. 10 to 15 breaths per minute
Answer: C
Rationale: The normal range for adult respirations is 12 to 20 breaths per minute.
9. Systolic blood pressure represents:
A. The pressure when the heart is at rest
B. The pressure when the heart contracts
C. The lowest pressure in the arteries
D. The average of three readings
Answer: B
