1. A client is prescribed Ranitidine. Which of the following laboratory results should be monitored by the nurse?

A. Complete blood count (CBC).
B. Serum creatinine.
C. Serum potassium.
D. Serum glucose.

Correct answer: A

Rationale: Ranitidine can potentially lead to blood dyscrasias, necessitating the monitoring of the client's CBC. Checking the CBC can help detect any abnormalities in blood cell counts and assess the client's overall hematologic status during Ranitidine therapy.

2. A client is being taught about taking Tetracycline to treat a GI infection caused by Helicobacter pylori. Which of the following statements should indicate to the nurse that the client understands the instructions?

A. I will take this medication with 8 ounces of milk.
B. I will inform my doctor if I experience diarrhea.
C. I can discontinue this medication when I feel completely well.
D. I can take this medication just before bedtime.

Correct answer: B

Rationale: The correct answer is B. Diarrhea can indicate the development of a suprainfection, which can be serious. Therefore, it is essential for the client to notify the healthcare provider if they experience diarrhea while taking Tetracycline to treat a GI infection caused by Helicobacter pylori. Choices A, C, and D are incorrect because taking Tetracycline with milk can reduce its absorption, discontinuing the medication prematurely can lead to treatment failure, and taking it just before bedtime may increase the risk of esophageal irritation due to the potential reflux of the medication.

3. Which medication is contraindicated with Nitroglycerin?

A. Hydrochloroquine
B. Methylprednisolone
C. Phenazopyridine
D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.

4. What classification of drug is Penicillin?

A. Antiarrhythmic
B. Anticonvulsant
C. Antibacterial
D. Mood stabilizer

Correct answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).

5. A client has a new prescription for Ferrous sulfate. Which of the following instructions should be included?

A. Take this medication with milk.
B. Take this medication on an empty stomach.
C. Take this medication before bedtime.
D. Take this medication with antacids.

Correct answer: B

Rationale: The correct answer is B: 'Take this medication on an empty stomach.' Ferrous sulfate is best absorbed on an empty stomach. Instruct the client to take it 1 hour before or 2 hours after meals to maximize absorption and avoid interactions with food or beverages that may decrease absorption. Choice A is incorrect because taking Ferrous sulfate with milk can decrease its absorption. Choice C is incorrect as there is no specific benefit to taking it before bedtime. Choice D is incorrect as antacids can interfere with the absorption of Ferrous sulfate.
