Nursing Elites

1. What is the action of Metformin?

• A. Decreasing intestinal glucose absorption
• B. Increasing sensitivity to insulin
• C. Decreasing hepatic glucose production
• D. All of the above

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 client who has been taking prednisone to treat asthma is advised to discontinue the medication. The client should be instructed to reduce the dose gradually to prevent which of the following adverse effects?

• A. Hyperglycemia
• B. Adrenocortical insufficiency
• C. Severe dehydration
• D. Rebound pulmonary congestion

Correct answer: B

Rationale: Abruptly stopping prednisone can result in adrenocortical insufficiency due to suppression of the adrenal glands. Gradually tapering the dose helps the body adjust and resume its natural cortisol production, preventing adrenal insufficiency. Choice A, hyperglycemia, is a possible adverse effect of prednisone, but it is not the primary reason for gradual tapering. Severe dehydration (Choice C) and rebound pulmonary congestion (Choice D) are not typically associated with discontinuing prednisone.

3. A client is starting therapy with Metformin. Which of the following instructions should be included by the healthcare provider?

• A. Take this medication with your first bite of food.
• B. Take this medication on an empty stomach.
• C. Take this medication before bedtime.
• D. Take this medication every other day.

Correct answer: A

Rationale: The correct answer is A: 'Take this medication with your first bite of food.' Metformin should be taken with meals to reduce gastrointestinal side effects and ensure better absorption. By taking the medication with the first bite of food, the client can help minimize potential stomach upset and improve the drug's effectiveness. Choice B is incorrect because taking Metformin on an empty stomach can increase the risk of gastrointestinal side effects. Choice C is incorrect as there is no specific recommendation to take Metformin before bedtime. Choice D is incorrect because Metformin is typically taken daily, not every other day, as prescribed by the healthcare provider.

4. What is the expected pharmacological action of propranolol?

• A. Block stimulation of beta1 receptors
• B. Alter water and electrolyte transport in the large intestine
• C. Block stimulation of beta2 receptors
• D. Both A and C are correct

Correct answer: D

Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.

5. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?

• A. Folic acid
• B. Vitamin D
• C. Calcium
• D. Iron

Correct answer: A

Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.
