Nursing Elites

1. Which of the following is considered a class IA Sodium Channel blocker?

• A. Mexiletine
• B. Amiodarone
• C. Quinidine
• D. Procainamide

Correct answer: D

Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.

2. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?

• A. Abdominal cramps
• B. Calf pain
• C. Headache
• D. Blurred vision

Correct answer: C

Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.

3. 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.

4. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?

• A. These medications work by inhibiting enzymes to prevent HIV replication.
• B. These medications work by preventing protein synthesis within the HIV cell.
• C. These medications work by weakening the cell wall of the HIV virus.
• D. These medications work by blocking HIV entry into cells.

Correct answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.

5. A client with OCD has a new prescription for Paroxetine. Which of the following instructions should the nurse include?

• A. It can take several weeks before you feel like the medication is helping.
• B. Take the medication just before bedtime to promote sleep.
• C. You should take the medication when needed for obsessive urges.
• D. Monitor for weight gain while taking this medication.

Correct answer: A

Rationale: The correct answer is A. Paroxetine, an antidepressant commonly used for OCD, typically takes 1 to 4 weeks before the client experiences the full therapeutic benefit. Therefore, informing the client that it may take several weeks before feeling the medication's effects is crucial to manage expectations and ensure compliance with the treatment plan. Choice B is incorrect because Paroxetine is usually taken in the morning due to its activating effects and may cause insomnia if taken before bedtime. Choice C is incorrect because Paroxetine should be taken regularly as prescribed, not just when experiencing obsessive urges. Choice D is incorrect because although weight gain can be a side effect of Paroxetine, it is not a priority instruction compared to the delayed onset of therapeutic effects.
