Question 1 of 5
The nurse should measure rectal temperatures in which of these patients?
Correct Answer: C
Rationale: The correct answer is C because rectal temperatures are most accurate in patients who are unable to hold a thermometer in their mouth, such as comatose adults. Rectal temperatures closely reflect core body temperature. Choice A (school-age child) may be able to hold a thermometer in their mouth. Choice B (older adult) may have conditions affecting rectal tissue. Choice D (patient receiving oxygen by nasal cannula) may have altered oxygen levels affecting temperature readings.
Question 2 of 5
When checking for proper blood pressure cuff size, which guideline is correct?
Correct Answer: D
Rationale: The correct answer is D because the width of the rubber bladder should ideally be around 40% of the arm circumference for proper blood pressure measurement. This is crucial for accurate readings as using a cuff that is too narrow or too wide can lead to incorrect readings. Option A is incorrect as one size does not fit all. Option B is incorrect as the length of the bladder is not the key factor. Option C is incorrect as the width of the bladder should be around 40%, not 80%, of the arm circumference.
Question 3 of 5
An older adult woman is brought to the emergency department after being found lying on the kitchen floor for 2 days; she is extremely dehydrated. What would the nurse expect to see during the examination?
Correct Answer: B
Rationale: The correct answer is B: Dry mucous membranes and cracked lips. Dehydration leads to reduced moisture in the body, resulting in dryness of mucous membranes and lips. This is a sign of fluid imbalance and severe dehydration. Smooth mucous membranes (choice A) may indicate adequate hydration. Pale mucous membranes (choice C) could suggest anemia or poor perfusion, not solely dehydration. White patches on mucous membranes (choice D) are usually associated with fungal infections, not dehydration.
Question 4 of 5
A 52-year-old woman has a papule on her nose that has rounded, pearly borders and a central red ulcer. She said she first noticed it several months ago and that it has slowly grown larger. The nurse suspects which condition?
Correct Answer: B
Rationale: The correct answer is B: Basal cell carcinoma. This type of skin cancer commonly presents as a pearly papule with rolled borders and a central ulcer. The slow growth over months is also characteristic of basal cell carcinoma. Acne (choice A) typically presents with comedones and inflammatory papules, not with the described characteristics. Melanoma (choice C) usually presents as an asymmetric, irregularly bordered lesion with variable colors. Squamous cell carcinoma (choice D) often appears as a scaly or crusted plaque, not a pearly papule with central ulcer.
Question 5 of 5
The nurse is performing an otoscopic examination on an adult. Which of these actions is correct?
Correct Answer: C
Rationale: The correct action is pulling the pinna up and back before inserting the speculum. This helps straighten the ear canal for better visualization. Tilting the head forward (A) does not aid in the examination. Releasing traction (B) can cause the speculum to move out of place. Using the smallest speculum (D) may not provide adequate visualization.
