Nursing Elites

1. Which drug classes are NOT typically used to treat angina?

• A. Calcium channel blockers
• B. Organic nitrates
• C. Alpha blockers
• D. Beta blockers

Correct answer: C

Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.

2. A client has a new prescription for Omeprazole. Which of the following instructions should the nurse include?

• A. Take this medication before meals.
• B. Take this medication with food.
• C. Take this medication at bedtime.
• D. Take this medication with antacids.

Correct answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that is most effective in reducing stomach acid production when taken before meals. This timing helps the medication work optimally by inhibiting acid secretion that occurs in response to food intake. Choice B ('Take this medication with food') is incorrect because Omeprazole should be taken before meals. Choice C ('Take this medication at bedtime') is incorrect as the optimal timing is before meals, not at bedtime. Choice D ('Take this medication with antacids') is incorrect because Omeprazole should not be taken with antacids as they can interfere with its absorption.

3. What is the therapeutic action of Phenytoin?

• A. Antidiabetic
• B. Anticonvulsant
• C. Mood stabilizer
• D. Antianxiety agent

Correct answer: B

Rationale: Phenytoin is primarily used as an anticonvulsant to prevent and control seizures. It works by stabilizing electrical activity in the brain, making it effective in managing conditions like epilepsy. Antidiabetic medications are used to regulate blood sugar levels, mood stabilizers help manage mood disorders, and antianxiety agents are used to reduce anxiety symptoms, none of which are the primary therapeutic action of Phenytoin.

4. A healthcare professional is preparing to initiate IV therapy for an older adult client. Which of the following actions should the professional plan to take?

• A. Use an electric shaver to remove excess hair on the extremity.
• B. Select the antecubital area to insert the IV catheter.
• C. Distend the veins by using a blood pressure cuff.
• D. Instruct the client to keep the extremity still during the procedure.

Correct answer: C

Rationale: Distending the veins using a blood pressure cuff is essential for facilitating visualization and access to the veins during IV catheter insertion. This technique helps healthcare professionals identify suitable veins, reducing the risk of complications like infiltration or hematoma formation. Using an electric shaver to remove hair on the extremity (Choice A) may increase the risk of micro-cuts and introduce infection. Selecting the antecubital area (Choice B) may not always be appropriate, as vein condition and accessibility vary among older adult clients. Instructing the client to keep the extremity still (Choice D) is important but is not directly related to preparing for IV therapy.

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.
