Correct Answer: C

Rationale: The correct action for the nurse to take before performing a closed intermittent bladder irrigation is to apply sterile gloves. Sterile gloves help maintain asepsis, reduce the risk of infection, and ensure patient safety during the procedure. Aspirating the irrigation solution from the bladder (Choice A) is not a standard step in closed intermittent bladder irrigation. Inserting the tip of the irrigation syringe into the catheter opening (Choice B) can introduce contaminants into the system. Opening the flow clamp to the irrigating fluid infusion tubing (Choice D) should only be done after ensuring all equipment is ready and the nurse is gloved to maintain sterility.

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: C

Rationale: The correct answer is C. An SPF of at least 15 is recommended to effectively protect against harmful UV rays. A sunscreen with an SPF of 10 is insufficient and does not provide adequate protection against skin cancer. Choices A, B, and D demonstrate good understanding of sun protection measures, such as avoiding peak sun hours, wearing protective clothing like a wide-brimmed hat, and reapplying sunscreen every 2 hours, which are all effective strategies to prevent skin cancer.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to advise the client to eat foods that are rich in potassium. Furosemide is a loop diuretic that can cause the loss of potassium, leading to hypokalemia. Eating foods high in potassium can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide does not directly interact with magnesium. Choice B is incorrect because furosemide is usually taken in the morning to prevent nighttime diuresis. Choice D is incorrect because furosemide is a diuretic that typically leads to a decrease in blood pressure rather than an increase.

Correct Answer: A

Rationale: Lip-smacking is a symptom of tardive dyskinesia, a long-term side effect of antipsychotic medications like haloperidol, characterized by involuntary movements of the face and jaw. Agranulocytosis (Choice B) is a rare but serious side effect of some medications, characterized by a dangerously low white blood cell count. Clang association (Choice C) is a thought disorder characterized by the association of words based on sound rather than meaning. Alopecia (Choice D) refers to hair loss, which is not a known long-term side effect of haloperidol.
