Rationale: Corrected Rationale: Metformin should be taken with food to minimize gastrointestinal side effects. Choice A is the correct answer as taking metformin with meals can help reduce the likelihood of experiencing gastrointestinal side effects like diarrhea and nausea, which are common side effects of metformin. Choice B is incorrect because metformin actually helps lower blood sugar levels and does not cause hyperglycemia. Choice C is incorrect as metformin is usually taken twice or even three times a day, not just once daily. Choice D is incorrect because metformin is an oral medication, not an injectable one.

Rationale: The correct answer is D: Airborne. Tuberculosis is spread through small droplets that remain airborne for longer periods, hence requiring airborne precautions. Choice A - Contact precautions are used for diseases spread by direct or indirect contact. Choice B - Droplet precautions are for diseases transmitted by large respiratory droplets that can travel short distances. Choice C - Protective isolation is not necessary for tuberculosis, as it is not spread through contact with the client.

Rationale: The nurse should instruct the client to liberally apply prescribed lotion to the treatment area. Prescribed hydrating lotions help soothe and protect irradiated skin, reducing dryness, redness, and scaling. Sitting in the sun can further damage the skin. Applying moist heat may exacerbate the skin condition. Washing the area with antimicrobial soap can be too harsh and further irritate the skin.

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.

The main focus in assessing for DVT is recognizing the signs and symptoms related to venous thrombosis.

Correct Answer: D
