Correct Answer: D

Rationale: The correct answer is D: 'You may experience diarrhea with this medication.' Diarrhea is a common side effect of metformin, particularly when initiating the medication. It is important for clients to be aware of this potential side effect. Option A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Option B is not directly related to metformin use. Option C is incorrect as muscle pain is not a common side effect of metformin and does not warrant stopping the medication.

Correct Answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

Correct Answer: C

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.

Correct Answer: B

Rationale: Asking the client what the voices are saying is the priority action as it helps assess the content of the hallucinations. This assessment is crucial to determine if the client is at risk of harm to themselves or others. Encouraging the client to listen to music or providing a distraction may not address the underlying issues related to the hallucinations. Administering antipsychotic medication, although important, should come after a thorough assessment of the hallucinations to ensure the right medication and dosage are provided.

Correct Answer: B

Rationale: The correct intervention for a client with deep vein thrombosis (DVT) is to apply warm, moist compresses to the affected leg. This helps alleviate pain and improve circulation in the affected area, aiding in the treatment of DVT. Encouraging the client to ambulate frequently (Choice A) is contraindicated as it can dislodge the clot and lead to complications. Massaging the affected leg (Choice C) is also contraindicated as it can dislodge the clot and potentially cause an embolism. Placing the client in a supine position (Choice D) is not specifically indicated for DVT treatment; elevation of the affected leg is preferred over placing the client completely supine.
