1. A client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the nurse?

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

2. Why is it important to monitor ins and outs in patients using ACE inhibitors?

A. To assess for renal impairment
B. To ensure the patient is receiving adequate fluid intake
C. To assess the patient for potential heart failure
D. To assess for NSAID use

Correct answer: A

Rationale: It is crucial to monitor ins and outs in patients using ACE inhibitors to assess for renal impairment. ACE inhibitors can affect renal function, potentially leading to renal impairment. Monitoring the patient's fluid balance helps in early recognition of any renal issues and allows for timely interventions to prevent complications.

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 has a new prescription for Losartan. Which of the following client statements indicates an understanding of the teaching?

A. I will increase my intake of potassium-rich foods.
B. I will take the medication with a full glass of milk.
C. I should monitor my blood pressure weekly.
D. I will take the medication every other day.

Correct answer: C

Rationale: The correct answer is C: 'I should monitor my blood pressure weekly.' Monitoring blood pressure regularly is crucial for clients taking Losartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. This medication works to dilate blood vessels, lowering blood pressure, so monitoring is essential to assess its effectiveness. Choices A, B, and D are incorrect because increasing potassium-rich foods can be harmful due to the potassium-sparing effect of Losartan, taking the medication with milk is not recommended, and adherence to the prescribed daily dosing schedule is necessary for optimal therapeutic outcomes.

5. What is the therapeutic class of Valproate?

A. Anticoagulant
B. Antianxiety, benzodiazepines
C. Anticonvulsant, vascular headache suppressant
D. Mood stabilizer

Correct answer: C

Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.
