Correct Answer: B

Rationale: Obtaining printed information on insulin self-administration should be the nurse's first priority. This action ensures that the client has the necessary knowledge to safely self-administer insulin at home. Providing the client with printed information (Choice A) is essential to empower the client with the required knowledge before considering additional resources. Making a copy of the medication reconciliation form for the client (Choice C) is important for documentation purposes but not as urgent as ensuring the client's understanding of insulin administration. Determining the client's ability to afford insulin administration supplies (Choice D) is crucial but should follow after ensuring the client is equipped with the necessary information for safe self-administration.

Correct Answer: B

Rationale: Using a regular blood pressure cuff on a morbidly obese client will lead to a falsely high blood pressure reading. This occurs because the cuff is not appropriately sized for the client's arm circumference, resulting in increased pressure on the artery and an inaccurate high reading. Choice A is incorrect because the reading will be falsely high, not low. Choice C is incorrect as the reading will not be accurate with an incorrectly sized cuff. Choice D is incorrect because the reading will be affected by using the wrong cuff size.

Correct Answer: A

Rationale: The correct answer is to assign the assistive personnel to assist the client with a partial bed bath. This task falls within the scope of practice for assistive personnel and is a common activity in caring for clients who have had a stroke. Choice B involves measuring blood pressure, which should be done by a licensed nurse. Choice C requires the use of a communication board, which can be done by any healthcare team member, not just assistive personnel. Choice D involves feeding the client, which may require assessment and intervention by a licensed nurse to ensure proper nutrition and safety.

Correct Answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

Correct Answer: A

Rationale: Crohn's disease is known to impair calcium absorption, which can lead to hypocalcemia. This condition affects the intestines and can disrupt the normal absorption of nutrients, including calcium. Postoperative status following appendectomy, history of bone cancer, and hyperthyroidism are typically not directly associated with a higher risk of developing hypocalcemia compared to Crohn's disease.
