1. A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?

A. Serum potassium
B. Serum sodium
C. Serum calcium
D. Serum magnesium

Correct answer: A

Rationale: Corrected Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia. The nurse should monitor the client's serum potassium levels closely because Losartan can increase potassium levels, potentially leading to serious complications such as arrhythmias. Monitoring serum sodium, calcium, or magnesium levels is not typically necessary when a patient is prescribed Losartan, as these values are not directly affected by this medication.

2. 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.

3. A client is starting therapy with rituximab. Which of the following findings should the nurse instruct the client to report?

A. Dizziness
B. Fever
C. Urinary frequency
D. Dry mouth

Correct answer: B

Rationale: The nurse should instruct the client to report fever when starting rituximab therapy. Fever can be a sign of infection, which is a potential complication associated with rituximab. Early detection and treatment of infections are important to ensure the client's safety and well-being. Dizziness, urinary frequency, and dry mouth are not commonly associated with rituximab therapy and are less likely to be directly related to the medication's side effects. Therefore, fever is the most crucial symptom to report to healthcare providers.

4. A client is being discharged with a new prescription for Clopidogrel. Which of the following instructions should the nurse include?

A. Avoid taking aspirin while on this medication.
B. Take this medication with food.
C. Avoid eating foods high in potassium.
D. Take this medication at bedtime.

Correct answer: A

Rationale: The correct instruction for a client prescribed Clopidogrel is to avoid taking aspirin while on this medication. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can potentiate the risk of bleeding, so they should be avoided while taking Clopidogrel to prevent adverse effects. Choices B, C, and D are incorrect because Clopidogrel does not need to be taken with food, there is no specific dietary restriction related to potassium, and the timing of administration (bedtime) is not a critical instruction for this medication.

5. In which of the following cases is Lansoprazole not used?

A. Gastritis
B. Peptic Ulcers
C. Zollinger-Ellison syndrome
D. Thalamus hypertrophy

Correct answer: D

Rationale: Lansoprazole is a proton pump inhibitor mainly used to treat conditions related to the stomach, such as gastritis, peptic ulcers, and Zollinger-Ellison syndrome. Thalamus hypertrophy is not a condition that Lansoprazole is indicated for; it is used for gastrointestinal issues and not neurological conditions.
