Health Assessment Vital Signs Quizlet Questions
Question 1 of 5
The nurse is caring for an infant and is obtaining the patient's vital signs. Which artery will the nurse use to best obtain the infant's pulse?
Correct Answer: B
Rationale: In infants, the brachial artery is preferred for pulse due to accessibility and strength; radial is weak and hard to palpate. Femoral and popliteal are less practical. Choice B is correct, per pediatric norms, ensuring accurate infant pulse assessment.
Question 2 of 5
According to the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, high blood pressure for adults is defined as...
Correct Answer: D
Rationale: NHLBI defines hypertension as 140 mmHg systolic or 90 mmHg diastolic , aligning with clinical standards (e.g., JNC 8). 120/80 is normal/prehypertension. 100/50 is low. 150/100 exceeds but isn't the threshold. Choice D is correct, reflecting NHLBI criteria nurses use to identify and manage high BP, a major cardiovascular risk factor.
Question 3 of 5
When focusing on temperature regulation of newborns and infants, the nurse understands that
Correct Answer: D
Rationale: Newborns lose heat rapidly from their heads; a cap prevents this. Infant and elderly temps differ . Infants' mechanisms are immature . Range doesn't increase with age . Choice D is correct, per neonatal care standards (e.g., AAP).
Question 4 of 5
The nurse is caring for a newborn infant in the hospital nursery. She notices that the infant is breathing rapidly but is pink, warm, and dry. The nurse knows that the normal respiratory rate for a newborn is breaths per minute.
Correct Answer: A
Rationale: Newborn RR is 30-60 ; rapid breathing fits if within this, with pink/warm/dry indicating normality. Lower ranges (B, C, D) apply to older ages. Choice A is correct, per neonatal norms.
Question 5 of 5
A nurse is assessing a client's blood pressure and finds it to be 160/90 mmHg. What action should the nurse take?
Correct Answer: C
Rationale: 160/90 mmHg indicates hypertension; initiating antihypertensive medication is appropriate with orders. It's not normal . Waiting delays care. Salt worsens BP. Choice C is correct, per the explanation, reflecting nursing intervention for high BP.
