UNAR Vital Signs Measurement 1 — Questions and Answers
Question 1: What is the normal adult resting heart rate?
- 60-100 beats per minute (Correct answer)
- 30-50 beats per minute
- 120-150 beats per minute
- 200+ beats per minute
Correct answer: 60-100 beats per minute
Normal resting heart rate for adults ranges from 60-100 bpm; athletes may have lower rates.
Question 2: What is the normal body temperature range?
- 97.8°F to 99.1°F (36.5°C to 37.3°C) (Correct answer)
- 100°F to 102°F
- 95°F to 96°F
- 103°F to 105°F
Correct answer: 97.8°F to 99.1°F (36.5°C to 37.3°C)
Normal body temperature has a small range around 98.6°F/37°C with slight individual variation.
Question 3: How is blood pressure measured?
- Using a stethoscope and sphygmomanometer, listening for Korotkoff sounds over the brachial artery (Correct answer)
- Only by palpation
- Using a thermometer
- By counting pulse rate
Correct answer: Using a stethoscope and sphygmomanometer, listening for Korotkoff sounds over the brachial artery
Blood pressure measurement requires listening for the appearance and disappearance of Korotkoff sounds.
Question 4: What does systolic vs. diastolic blood pressure represent?
- Systolic is the pressure during heart contraction; diastolic is the pressure during heart relaxation (Correct answer)
- They are the same measurement
- Systolic is always lower
- Diastolic measures heart rate
Correct answer: Systolic is the pressure during heart contraction; diastolic is the pressure during heart relaxation
The top number (systolic) reflects the force during heartbeats; the bottom (diastolic) reflects pressure between beats.
Question 5: How is respiration counted?
- Count breaths for 30-60 seconds without telling the patient, noting rate, depth, and pattern (Correct answer)
- Only count for 10 seconds
- Tell the patient to breathe normally
- Count only inhales
Correct answer: Count breaths for 30-60 seconds without telling the patient, noting rate, depth, and pattern
Respirations should be counted covertly because awareness can change breathing patterns.
Question 6: What are the signs of abnormal vital signs that should be reported?
- Temperature above 101°F or below 97°F, pulse below 60 or above 100, BP above 140/90 or below 90/60 (Correct answer)
- Only extremely high values
- No vital sign changes need reporting
- Only temperature changes matter
Correct answer: Temperature above 101°F or below 97°F, pulse below 60 or above 100, BP above 140/90 or below 90/60
Abnormal vital signs may indicate deteriorating condition and require prompt reporting to the nurse.
