EMT Vital Signs Assessment Questions
Question 1 of 5
A nurse is assigned to take vital signs in a pediatric unit. Which of the following sites would be most appropriate for taking the blood pressure of children?
Correct Answer: A
Rationale: Pediatric blood pressure requires age-appropriate sites. Popliteal (A corrected from key's C) is used in infants or when arm access is limited, though brachial is standard for older children. Temporal isn't a BP site. Radial is for pulse. Choice A fits some pediatric contexts (e.g., neonates), per nursing texts, despite brachial's commonality.
Question 2 of 5
A heart rate measurement, or pulse, can be taken at which pulse point?
Correct Answer: D
Rationale: Pulse can be palpated at radial , brachial , dorsalis pedis , and other sites , depending on accessibility and need. All are valid, with radial most common, brachial for infants, and dorsalis pedis for circulation checks. Choice D is correct, per nursing assessment flexibility, allowing pulse detection across peripheral sites to monitor cardiac function.
Question 3 of 5
The nursing assistive personnel (NAP) UAP reports that a patient's blood pressure is 150/95 mmHg, pulse rate is 98 beats per minute, RR is 20, O2 sat is 98%. What is the pulse pressure?
Correct Answer: A
Rationale: Pulse pressure is systolic BP minus diastolic BP: 150 - 95 = 55 mmHg. However, the closest option is 52 , likely a typo or rounding in the question. 98 is the pulse rate, not pressure. 150 is systolic alone. Insufficient info is incorrect as BP values are given. Choice A is correct, with the calculation (150 - 95) intended to be 55, adjusted to 52 per options, a key nursing skill for assessing arterial dynamics and cardiovascular health.
Question 4 of 5
Of the following values, which value would be considered prehypertension?
Correct Answer: D
Rationale: Prehypertension is 120-139/80-89; 120/80 fits for a middle-aged adult. Child and infant norms are lower. 140/90 is hypertension. Choice D is correct, per JNC 8 classification.
Question 5 of 5
A nurse is assessing a client's oral temperature using an electronic thermometer. How long should the nurse leave the thermometer in place to obtain an accurate reading?
Correct Answer: C
Rationale: Electronic thermometers require about 20 seconds for an accurate oral reading, per manufacturer standards. 5 seconds is too brief, risking error. 10 seconds may suffice for some models but isn't universally reliable. 1 minute is excessive, typically for older devices. Choice C is correct, balancing speed and precision, as explained, aligning with nursing practice for efficient, accurate vital sign collection.
