1. What is the classification of furosemide?

A. Loop diuretic
B. Anticoagulant
C. Iron supplement
D. Anticonvulsant

Correct answer: A

Rationale: Furosemide is classified as a loop diuretic, not an anticoagulant, iron supplement, or anticonvulsant. Loop diuretics, like furosemide, act in the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine output. This mechanism makes them effective in treating conditions such as edema and hypertension. Therefore, the correct classification for furosemide is a loop diuretic (Choice A).

2. When educating a client who has a prescription for Propranolol, what instruction should the healthcare provider include?

A. Take this medication with food.
B. Discontinue the medication if you feel fatigued.
C. Expect to have decreased heart rate with this medication.
D. Do not stop taking this medication abruptly.

Correct answer: D

Rationale: The correct instruction for a client with a prescription for Propranolol is not to stop taking the medication abruptly. Abrupt cessation can result in rebound hypertension or other cardiac complications. It is crucial for the client to taper off the medication gradually under healthcare provider supervision to prevent adverse effects. Choice A is incorrect because Propranolol can be taken with or without food. Choice B is incorrect as discontinuing the medication based on fatigue alone is not advisable without consulting a healthcare provider. Choice C is incorrect because while Propranolol can decrease heart rate, it is not the primary instruction to provide in this scenario.

3. A client has been prescribed a Beta Blocker for hypertension. Which of the following findings should the nurse monitor as an adverse effect of this medication?

A. Bradycardia
B. Hypertension
C. Hyperglycemia
D. Hypernatremia

Correct answer: A

Rationale: Bradycardia is the correct answer. Beta Blockers work by slowing down the heart rate, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is essential to prevent complications. Choices B, C, and D are incorrect because Beta Blockers do not typically cause hypertension, hyperglycemia, or hypernatremia as adverse effects.

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

A. Take the medication in the morning.
B. Increase intake of potassium-rich foods.
C. Avoid sun exposure while taking this medication.
D. Limit fluid intake to 1 liter per day.

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.

5. What are the actions of the drug metformin?

A. Decreases hepatic glucose production and intestinal glucose absorption
B. Increases sensitivity to insulin
C. Short-term sedation
D. Both A and B

Correct answer: D

Rationale: Metformin has dual actions by decreasing hepatic glucose production and intestinal glucose absorption, which helps in reducing blood glucose levels. Additionally, it increases sensitivity to insulin, aiding in its proper utilization within the body. Choice A is correct as metformin acts by decreasing hepatic glucose production and intestinal glucose absorption. Choice B is also correct as metformin increases sensitivity to insulin. Choice C, short-term sedation, is incorrect as metformin is not known for causing sedation. Therefore, the correct answer is D because metformin performs both of these actions.
