Correct Answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

Correct Answer: B

Rationale: The ventrogluteal site is preferred for intramuscular injections in adults because it is free from major blood vessels and nerves, reducing the risk of injury. The deltoid muscle can be used for smaller volumes of medication, primarily vaccines. The vastus lateralis muscle is commonly used in infants, toddlers, and young children. The dorsogluteal muscle site is discouraged due to its proximity to the sciatic nerve, increasing the risk of injury or nerve damage.

Correct Answer: D

Rationale: In clients with altered renal function being treated at home, weekly weight is the most accurate indicator of fluid balance. Fluid retention or loss can significantly affect weight, making it a reliable measure. Choices A, B, and C are not as accurate indicators of fluid balance as weekly weight. Intake and output differences can vary in accuracy and may not capture all aspects of fluid balance. Changes in mucous membranes and skin turgor can be influenced by factors other than fluid balance, making them less precise indicators.

Correct Answer: B

Rationale: The correct recommendation for managing chemotherapy-induced fatigue is to advise the client to rest when needed and maintain a balanced diet. Increasing the dose of chemotherapy (Choice A) would exacerbate the fatigue and other side effects. While light physical activity (Choice C) can be beneficial, extreme fatigue may require more rest initially. Delaying chemotherapy treatment (Choice D) should only be considered after consultation with the healthcare provider, as timely treatment is usually crucial in cancer care.
