Vital Signs Assessment for Nurses Questions
Question 1 of 5
Hypothermia is defined as ...
Correct Answer: B
Rationale: Hypothermia is a core temperature below 95°F (35°C), but 96.8°F (36°C) is a practical threshold for early detection . An increase over 96.8°F suggests normothermia or fever. Cyanosis is a symptom, not hypothermia. ‘None' is incorrect. Choice B is correct, aligning with nursing definitions (e.g., CDC) where subnormal temperature signals risk, guiding interventions like warming to prevent complications.
Question 2 of 5
The patient requires temperatures to be taken every two hours. Which of the following cannot be delegated to nursing assistive personnel?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The physician order reads 'Lopressor (metoprolol) 50 mg PO daily. Do not give if blood pressure is less than 100 mm Hg systolic.' The patient's blood pressure is 92/66. The nurse does not give the medication and
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A nurse is assessing a client's oxygen saturation level. What is the most common method used to measure oxygen saturation?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A nurse has an order to take the core temperature of a patient. At which of the following sites would a core body temperature be measured?
Correct Answer: A
Rationale: Tympanic measures core temperature via the eardrum, close to the hypothalamus, per the answer key. Oral approximates core but varies with intake. Axillary and skin surface reflect peripheral temp, less accurate for core. Tympanic's proximity to central blood flow makes it reliable for quick, non-invasive core readings, aligning with nursing practice for accuracy in critical assessments, distinguishing it from less precise peripheral sites.
