Correct Answer: C

Rationale: The correct answer is C, Disturbed body image related to the incision scar. This is the most appropriate nursing diagnosis as the client's concern about wearing a scarf around his neck post-surgery indicates a potential disturbance in body image. This diagnosis addresses the client's emotional response to physical changes, which is common in surgical patients. Choice A is incorrect because impaired physical mobility is not directly related to the client's worry about wearing a scarf. Choice B is incorrect as ineffective denial does not directly address the client's specific concern about body image. Choice D is also incorrect as the risk of injury is not the primary issue in this scenario; it is more about the client's perception of their appearance post-surgery. In summary, the client's worry about wearing a scarf post-surgery indicates a disturbance in body image, making choice C the most appropriate nursing diagnosis.

Correct Answer: E

Rationale: The correct answer is not provided in the choices. However, if I were to choose from the given options, the most appropriate would be C: "Because they are prone to reduced renal efficiency." This is important because older adults may have decreased kidney function, leading to potential complications with IV therapy. Option A is incorrect as defense mechanisms are not directly related to monitoring IV therapy. Option B is incorrect as fluid overload is a general concern with IV therapy regardless of age. Option D is irrelevant to the need for monitoring IV therapy in older adults.

Correct Answer: A

Rationale: The correct answer is A: Administering an oral dose of levothyroxine (Synthroid). In myxedema coma, there is severe hypothyroidism leading to altered mental status, hypothermia, and organ failure. Administering levothyroxine is crucial to replace the deficient thyroid hormone rapidly and restore metabolic function. Warming the client (B) is important but secondary to addressing the underlying hormonal imbalance. Measuring intake and output (C) is essential for overall assessment but not the most critical intervention. Maintaining a patent airway (D) is always important in any medical emergency but does not directly address the primary issue of hypothyroidism in myxedema coma.

Correct Answer: D

Rationale: The correct answer is D: Draw up clear insulin first when mixing two types of insulin in one syringe. This is important because mixing insulin requires drawing up the clear (short-acting) insulin first to prevent contamination. This ensures accurate dosing and prevents clouding of the insulin. Drawing up cloudy insulin first can lead to inaccurate dosing and potential mixing errors. Administering insulin after the first meal (choice A) is not the focus of this question. Administering insulin at a 45-degree angle into the deltoid muscle (choice B) is not recommended for insulin injections. Vigorously shaking the vial of insulin before withdrawal (choice C) can cause bubbles and affect the accuracy of the dose.

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.
