1. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?

A. Perform immediate gastric lavage.
B. Prepare the client for hemodialysis.
C. Administer an additional oral dose of lithium.
D. Request a stat repeat of the laboratory test.

Correct answer: A

Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.

2. A healthcare professional is teaching a client who has a new prescription for Clopidogrel. Which of the following laboratory values should the healthcare professional monitor to assess for potential adverse effects?

A. White blood cell count
B. Platelet count
C. Hemoglobin
D. Blood glucose

Correct answer: B

Rationale: Clopidogrel is an antiplatelet medication that works by preventing blood clots. Monitoring the patient's platelet count is essential because a decrease in platelet count can increase the risk of bleeding. By assessing the platelet count, the healthcare professional can detect any potential adverse effects related to the medication and take appropriate actions to prevent complications. White blood cell count, hemoglobin, and blood glucose levels are not directly affected by Clopidogrel, so they are not the primary values to monitor for potential adverse effects of this medication.

3. A client is starting a new prescription for enalapril. Which of the following instructions should the nurse include?

A. Take the medication with food.
B. Rise slowly from a sitting position.
C. Avoid salt substitutes.
D. Avoid exposure to sunlight.

Correct answer: C

Rationale: The correct instruction for a client starting enalapril is to avoid salt substitutes. Salt substitutes may contain potassium, which could lead to elevated potassium levels when combined with enalapril, increasing the risk of hyperkalemia. Choices A, B, and D are incorrect because there is no specific need to take enalapril with food, rise slowly from a sitting position, or avoid exposure to sunlight when taking this medication.

4. What is the action of Nitroglycerin?

A. Dilates the Bronchi
B. Reduces Blood Glucose
C. Reduces Nausea
D. Dilates Coronary Arteries

Correct answer: D

Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.

5. Which of the following is classified as a class IA Sodium Channel blocker?

A. Quinidine
B. Disopyramide
C. Aminodarone
D. Propafenone

Correct answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
