ATI Vital Signs Assessment Questions
Question 1 of 5
The nurse is assessing a patient's cranial nerve function and asks the patient to raise both eyebrows. Which cranial nerve is being tested?
Correct Answer: B
Rationale: Step-by-step rationale: 1. Choice B, Cranial nerve VII (facial nerve), is correct. This nerve innervates the muscles responsible for facial expressions, including raising the eyebrows. 2. Cranial nerve III (choice A) controls eye movements, not eyebrow elevation. 3. Cranial nerve IX (choice C) is involved in swallowing and taste sensation, not eyebrow movement. 4. Cranial nerve X (choice D) is responsible for various functions including regulating the heart and digestive system, not eyebrow movement. Summary: Choice B is correct as the facial nerve controls the muscles involved in raising the eyebrows. Choices A, C, and D are incorrect as they are not specifically associated with eyebrow movement.
Question 2 of 5
Which groups body temperature changes more rapidly in response to both heat and cold air temperatures?
Correct Answer: A
Rationale: Infants and children, is correct because their higher surface-area-to-mass ratio and immature thermoregulation cause rapid temperature shifts. Infants lack shivering efficiency and sweat less, while childrens thin skin and high metabolism amplify responses to heat/cold. Older adults, adapt slowly due to reduced metabolism and circulation. Women, and Men, vary less by sex than age. Pediatric nursing notes infants can drop to hypothermia or spike to hyperthermia fastere.g., a cold room lowers temperature in minutes. This vulnerability requires close monitoring, making A the precise answer per developmental physiology.
Question 3 of 5
Which of the following patients would be an appropriate candidate for the use of a radiant heater?
Correct Answer: B
Rationale: Radiant heaters provide controlled warmth, ideal for specific patients. An older adult with hypothermia needs warming but typically via blankets or warm fluids, not radiant heaters. A premature infant requires thermoregulation due to immature systems, making radiant heaters standard in neonatal care. An infant with jaundice uses phototherapy, not heat. A near-drowning child needs rewarming but not specifically via radiant heaters. Choice B is correct as premature infants' inability to maintain body temperature aligns with radiant heater use, a common NICU intervention supported by pediatric nursing protocols.
Question 4 of 5
The patient requires routine temperature assessment but is confused, easily agitated, and has a history of seizures. Which route will the nurse use to obtain the patient's temperature?
Correct Answer: D
Rationale: For a confused, agitated patient with seizures, tympanic is safest and fastest, avoiding oral risks (biting) or rectal invasiveness (agitation, seizure risk). Oral is unreliable with agitation. Rectal risks injury or vagal stimulation. Axillary is slow and less accurate. Choice D is correct, per nursing safety protocols, balancing accuracy and patient stability.
Question 5 of 5
The nursing assistive personnel (NAP) is taking vital signs and reports that a patient's blood pressure is abnormally low. What should the nurse do next?
Correct Answer: D
Rationale: Abnormally low BP requires verification and assessment. The nurse retaking it ensures accuracy and allows immediate patient evaluation, overriding NAP data. Retaking by NAP or adding vitals delays RN judgment. Ignoring it risks harm. Choice D is correct, per RN accountability standards.
