1. During a physical assessment, a nurse is assessing 4 adult clients. Which of the following physical assessment techniques should the nurse use?
- A. Ensure the bladder of the BP cuff surrounds 80% of their arm.
- B. Use the BP cuff on the forearm if the upper arm is not accessible.
- C. Apply the BP cuff loosely around the arm.
- D. Use a pediatric cuff for adults with small arms.
Correct answer: A
Rationale: The correct answer is to ensure the bladder of the BP cuff surrounds 80% of the arm. This technique is crucial for obtaining accurate blood pressure readings. Choice B is incorrect because using the BP cuff on the forearm may lead to inaccurate readings. Choice C is incorrect as applying the BP cuff loosely can also result in inaccurate measurements. Choice D is incorrect because using a pediatric cuff for adults with small arms would not provide accurate blood pressure readings.
2. A client is postoperative following knee arthroplasty and requires the use of a thigh-length sequential compression device. Which of the following actions should the nurse take?
- A. Ensure two fingers can fit under the sleeves.
- B. Ensure the device is not too tight to impede circulation.
- C. Position the client comfortably before applying the device.
- D. Use the device continuously to prevent blood clots.
Correct answer: A
Rationale: The correct action for the nurse to take when applying a thigh-length sequential compression device to a postoperative client is to ensure that two fingers can fit under the sleeves. This action helps prevent the device from being too tight, which could impede circulation. Choice B is incorrect because the device should not be too tight, as it could lead to circulation issues. Choice C is incorrect as the client should be in a comfortable position, not necessarily supine. Choice D is incorrect as sequential compression devices are typically used continuously to prevent blood clots.
3. The nurse is assessing a client with a diagnosis of pheochromocytoma. Which symptom should the nurse expect to find?
- A. Hypertension
- B. Bradycardia
- C. Hypoglycemia
- D. Weight gain
Correct answer: A
Rationale: The correct answer is A: Hypertension. Pheochromocytoma is characterized by the overproduction of catecholamines, leading to symptoms such as hypertension. Bradycardia (Choice B) is not typical in pheochromocytoma as increased catecholamines usually lead to tachycardia. Hypoglycemia (Choice C) and weight gain (Choice D) are not commonly associated symptoms of pheochromocytoma.
4. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?
- A. 400 mg
- B. 200 mg
- C. 1600 mg
- D. 100 mg
Correct answer: A
Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
5. Which of the following manifestations confirms the presence of pediculosis capitis in students?
- A. Scratching the head more than usual
- B. Flakes evident on a student's shoulders
- C. Oval pattern occipital hair loss
- D. Whitish oval specks sticking to the hair
Correct answer: D
Rationale: The correct answer is D. Whitish oval specks sticking to the hair shaft are nits, which are a definitive sign of pediculosis capitis (head lice). A: Scratching the head more than usual is a common symptom but not confirmatory of head lice infestation. B: Flakes evident on a student's shoulders may indicate dandruff or dry scalp, not necessarily head lice. C: Oval pattern occipital hair loss is not a typical manifestation of pediculosis capitis.
