Correct Answer: D

Rationale: The correct answer is D: Improve ability to hear. A hearing aid is designed to improve a person's ability to hear by amplifying sound. This helps individuals with hearing loss to better understand speech and sounds in their environment. A: Amplifying background noise is not the main purpose of a hearing aid. It may actually hinder the user's ability to focus on important sounds. B: Amplifying musical sounds is not the primary function of a hearing aid. The main focus is on improving speech understanding. C: Occluding the ear is not the purpose of a hearing aid. It is meant to enhance hearing, not block sound.

Correct Answer: C

Rationale: The correct answer is C: General to specific assessment. In this scenario, the nurse is starting with a broad assessment of the surgical dressing, which is a general observation, before moving on to more specific details. This approach allows the nurse to gather comprehensive information systematically. A: Gordon’s Functional Health Patterns involves assessing a patient's health across several categories, not specifically related to wound care. B: Activity-exercise pattern assessment focuses on the patient's physical activity and exercise routines, not the wound dressing. D: Problem-oriented assessment involves identifying and addressing specific health issues, rather than starting with a general observation like the appearance of a surgical dressing.

Correct Answer: B

Rationale: The correct answer is B: Offering emotional support. In the preoperative phase, a nurse's role includes comforting and reassuring the patient to reduce anxiety and promote emotional well-being. This is crucial for the patient's overall experience and can positively impact their recovery. Obtaining preoperative orders (A) is typically the responsibility of the physician. Explaining the surgical procedure (C) is usually done by the surgeon. Providing informed consent (D) involves ensuring the patient understands the risks and benefits of the procedure, which is typically the responsibility of the healthcare provider performing the procedure.

Correct Answer: D

Rationale: The correct answer is D because polyuria is a common complication of hypophysectomy, the surgical removal of the pituitary gland. The pituitary gland plays a crucial role in regulating water balance in the body, and its removal can lead to excessive urine production. Choices A, B, and C are incorrect because a decrease in stress does not typically cause polyuria, diabetes mellitus is not an immediate complication of surgery, and polyuria is not an expected result of pituitary gland removal.

Correct Answer: C

Rationale: Rationale: C: Practice conscientious hand washing is correct as it helps prevent the spread of infection. Proper hand hygiene is essential in reducing the risk of infection transmission to the client with Hodgkin's disease. A: Apply ice to the skin for brief periods is incorrect as it does not directly relate to preventing infection in the client. B: Provide cool sponge baths is incorrect as it mainly addresses comfort and hygiene but does not specifically target infection prevention. D: Use cotton gloves Restrict visitors or personnel with infections from contact with the client is incorrect because while using gloves can help prevent the spread of infection, restricting visitors with infections is not under the direct control of the nurse. Summary: Practicing conscientious hand washing is crucial in preventing infection in a client with Hodgkin's disease, while the other choices do not directly address infection control in this context.
