Correct Answer: D

Rationale: The correct answer is D, Serum albumin. Serum albumin levels are a good indicator of the nutritional effectiveness of total parenteral nutrition (TPN). Monitoring serum albumin levels helps assess the client's overall protein status and nutritional adequacy. Choices A, B, and C are not direct indicators of the effectiveness of TPN therapy. Serum calcium levels may be affected by other factors, blood glucose monitoring is more relevant for clients with diabetes or those receiving insulin therapy, and serum protein is not as specific as serum albumin in evaluating TPN effectiveness.

Correct Answer: D

Rationale: The correct answer is to apply a hydrocolloid dressing. For a stage 2 pressure injury, maintaining a moist environment is crucial for healing. Hydrocolloid dressings help achieve this by promoting autolytic debridement and creating a barrier against bacteria while allowing the wound to heal. Applying a dry dressing (Choice A) may not provide the necessary moisture for healing. Cleansing the wound with normal saline (Choice B) is essential, but a hydrocolloid dressing is more specific for promoting healing in this case. Performing debridement as needed (Choice C) is not typically indicated for stage 2 pressure injuries, as they involve partial-thickness skin loss without slough or eschar.

Correct Answer: C

Rationale: The correct answer is C because checking blood sugar levels every morning before breakfast is a crucial aspect of managing diabetes effectively. This practice helps individuals monitor their blood sugar levels regularly and adjust their treatment plan as needed. Option A is incorrect as consuming a bedtime snack based on blood sugar levels alone may not be an appropriate approach to managing diabetes. Option B is incorrect as relying on more sugar-free candy does not address the overall dietary management of blood sugar levels. Option D is incorrect as avoiding physical activity when blood sugar is below 100 mg/dL can hinder diabetes management, as exercise is generally beneficial for controlling blood sugar levels.

Correct Answer: A

Rationale: Furosemide is the correct answer. It is a common diuretic used in patients with heart failure to reduce fluid overload. Metoprolol (Choice B) is a beta-blocker often prescribed to manage heart failure symptoms by improving heart function. Digoxin (Choice C) is used in heart failure patients to help the heart beat stronger and with a more regular rhythm. Aspirin (Choice D) is not typically prescribed for heart failure but may be used in patients with heart disease for its antiplatelet effects.

Correct Answer: B

Rationale: The correct answer is B: Apply a hydrocolloid dressing. Applying a hydrocolloid dressing helps create a moist environment that promotes healing in clients with stage 2 pressure injuries. Choice A, cleansing the wound with povidone-iodine, is not recommended for stage 2 pressure injuries as it can be too harsh on the skin. Performing debridement as needed, as mentioned in choice C, is not typically indicated for stage 2 pressure injuries, which involve partial-thickness skin loss. Keeping the wound open to air, as stated in choice D, is also not the preferred approach for managing stage 2 pressure injuries, as maintaining a moist environment is key to promoting healing.
