Vital Signs Assessment Chapter 7 Questions
Question 1 of 5
Core body temperature is highest at:
Correct Answer: C
Rationale: Late afternoon, is correct because core body temperature peaks around 4 pm to 6 pm due to circadian rhythms governed by the hypothalamus. It rises throughout the day from a low of ~97°F (4-6 am) to a high of ~98.6°F-100°F, reflecting increased metabolic activity. Early morning, is the nadir, not peak. Noon, is midway, not the highest. Evening, sees a decline post-peak. Studies show this diurnal pattern in healthy adults, with late afternoon aligning with maximal alertness and physical performance. Nurses consider this when assessing fevere.g., a 99°F reading at 5 pm might be normal variation. Thus, C is accurate based on physiological circadian evidence.
Question 2 of 5
The patient is lying in bed under a ceiling fan. Which technique is the nurse using when the fan produces heat loss?
Correct Answer: C
Rationale: A ceiling fan moves air over the patient, causing heat loss via convection , where warm air around the body is replaced by cooler moving air. Radiation involves heat emission without contact, not fan-driven. Conduction requires direct contact (e.g., cold pack), not air movement. Evaporation involves moisture loss, not primarily fan-related here. Choice C is correct because convection matches the mechanism of air circulation enhancing heat dissipation, a principle nurses apply in thermoregulation strategies to cool patients effectively in clinical settings.
Question 3 of 5
The nurse is caring for a newborn infant in the hospital nursery and notices that the infant is breathing rapidly but is pink, warm, and dry. Which normal respiratory rate will the nurse consider when planning care for this newborn?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Some of the signs of respiratory distress are...
Correct Answer: D
Rationale: Respiratory distress includes grunting and nasal flaring as effort signs, raspy breathing from obstruction, and panicked look/sweating from stressall are indicators. Choice D is correct, as nurses identify these clinical signs per respiratory assessment protocols (e.g., PALS), prompting urgent intervention for airway or oxygenation problems.
Question 5 of 5
What is the best approach to take in exploring cultural considerations for patients in pain?
Correct Answer: C
Rationale: Individual assessment is best, as pain perception varies uniquely by culture, not stereotypes . Diversity doesn't negate cultural impact . Social workers assist but nurses primarily assess. Choice C is correct, per holistic nursing practice (e.g., ANA standards), ensuring patient-centered care by understanding personal cultural influences on pain expression and management.
