1. What is the action of Metformin?

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

2. A nurse is teaching a client who has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?

Correct answer: A

Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use.

3. A client in a substance abuse clinic is being assessed by a nurse after discontinuing disulfiram due to severe nausea and vomiting. What is the likely cause of the client's distress?

Correct answer: C

Rationale: Disulfiram, when combined with alcohol, leads to a severe reaction causing nausea and vomiting. Since the client experienced these symptoms after starting disulfiram, it is likely that they consumed alcohol while taking the medication. Choice A is incorrect because the symptoms are more indicative of the interaction with alcohol rather than an allergic response. Choice B is incorrect as severe nausea and vomiting are not common side effects of disulfiram alone. Choice D is incorrect as there is no indication of an overdose based on the symptoms described.

4. A client is admitted for a surgical procedure. Which preexisting condition can be a contraindication for the use of Ketamine as an intravenous anesthetic?

Correct answer: D

Rationale: Ketamine can produce psychological effects like hallucinations. Patients with schizophrenia may be more prone to experiencing exacerbation of their symptoms when exposed to Ketamine due to its potential to worsen psychotic symptoms. Therefore, schizophrenia can be a contraindication for the use of Ketamine as an anesthetic. Peptic ulcer disease, breast cancer, and diabetes mellitus are not contraindications for the use of Ketamine.

5. A client has a new prescription for hydrochlorothiazide to treat hypertension. Which of the following instructions should be included?

Correct answer: B

Rationale: The correct instruction that should be included for a client prescribed hydrochlorothiazide is to increase the intake of potassium-rich foods. Hydrochlorothiazide, being a diuretic, can lead to hypokalemia by enhancing potassium excretion. Increasing consumption of potassium-rich foods like bananas or oranges can help prevent hypokalemia and maintain electrolyte balance. Choices A, C, and D are incorrect. Taking the medication in the morning is not a specific instruction related to hydrochlorothiazide. Avoiding sun exposure is more relevant for photosensitive medications, not hydrochlorothiazide. Limiting fluid intake to 1 liter per day is not necessary unless specifically advised by a healthcare provider.
