Correct Answer: A

Rationale: The correct answer is to limit intake of processed foods. Processed foods are often high in sodium, which goes against the goal of a low-sodium diet. Fresh fruits and vegetables are recommended for a low-sodium diet due to their natural low sodium content. The use of accessory muscles and monitoring for allergic reactions are not related to dietary modifications for a low-sodium diet.

Correct Answer: A

Rationale: The correct answer is A: Swelling in the limb. Swelling, particularly in one limb, is a common sign of deep vein thrombosis (DVT) and should be assessed. This swelling is often accompanied by pain, redness, and warmth in the affected area. Choices B, C, and D are incorrect because decreased heart rate, increased appetite, and improved mobility are not typically associated with DVT. The main focus in assessing for DVT is recognizing the signs and symptoms related to venous thrombosis.

Correct Answer: C

Rationale: The correct answer is C. Stage 2 ulcers involve partial-thickness skin loss with visible and superficial damage, which may appear as an abrasion, blister, or shallow crater. Choice A describes a Stage 1 pressure ulcer characterized by intact skin with nonblanchable redness. Choice B describes a Stage 3 pressure ulcer with full-thickness tissue loss and damage to the subcutaneous tissue. Choice D is indicative of a Stage 4 pressure ulcer, involving full-thickness tissue loss with damage extending to muscle or bone.

Correct Answer: C

Rationale: The correct answer is C: 'Monitor for liver function.' Duloxetine is an antidepressant medication, not an antipsychotic, so choice A is incorrect. One of the common side effects of duloxetine is weight gain, making choice B incorrect. Choice D, stating that duloxetine has no side effects, is inaccurate as all medications have the potential for side effects. Monitoring liver function is crucial with duloxetine because it can impact liver function, emphasizing the importance of regular checks to ensure the client's safety.

Correct Answer: A

Rationale: The correct answer is A. Nitrofurantoin can cause a harmless brown discoloration of urine. Choice B is also correct as it should be taken with food to enhance absorption. Choice C is incorrect as nitrofurantoin does have side effects, such as gastrointestinal disturbances. Choice D is incorrect as nitrofurantoin is not recommended during the last month of pregnancy due to potential risks to the fetus.
