Vital Signs Assessment Chapter 7 Questions
Question 1 of 5
The nurse is assessing a patient's mental status and notes that the patient is unable to remember recent events. Which aspect of memory is impaired?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The nurse is performing a musculoskeletal assessment and notes that the patient has a decreased range of motion in the knee joint. What is the most likely cause of this finding?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 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 4 of 5
A nurse notices a student is taking a blood pressure measurement on a patient with a cuff that is too large. What should be the nurses response to the student?
Correct Answer: A
Rationale: A cuff too large underestimates blood pressure, leading to an incorrect reading , as it doesnt compress the artery properly. It wont cause significant injury or dangerous pressure , though a too-small cuff might. Korotkoff sounds remain audible but may be misread. Choice A is correct, emphasizing accuracy in measurement technique, a key teaching point for nursing students.
Question 5 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.
