1. At what amount does Acetaminophen stop effectively controlling pain?

A. Over 1,000 mg
B. 750 mg
C. Over 1,500 mg
D. 150 mg

Correct answer: A

Rationale: Acetaminophen is known to lose its effectiveness in controlling pain beyond a dosage of 1,000 mg. Taking more than 1,000 mg will not provide additional pain relief but can increase the risk of adverse effects. Choice B (750 mg) is incorrect because this amount is within the typical recommended dose range for Acetaminophen. Choice C (Over 1,500 mg) is incorrect as it suggests a higher dose than the point at which Acetaminophen starts to lose its effectiveness. Choice D (150 mg) is too low a dose to effectively control pain for most adults.

2. 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.

3. A nurse is teaching a client who has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?

A. Hyperkalemia
B. Hypoglycemia
C. Hypocalcemia
D. Hyponatremia

Correct answer: A

Rationale: Spironolactone is a potassium-sparing diuretic, so the nurse should monitor the client for hyperkalemia, which can cause muscle weakness and cardiac dysrhythmias.

4. A client has a prescription for Amoxicillin. Which of the following instructions should be included?

A. Take the medication with food.
B. Avoid taking the medication with milk.
C. Expect your stools to turn clay-colored.
D. Complete the entire course of therapy.

Correct answer: D

Rationale: The correct answer is D: Complete the entire course of therapy. It is crucial for clients to complete the entire course of amoxicillin therapy to ensure the infection is fully treated and to prevent antibiotic resistance. Prematurely stopping the antibiotic can lead to incomplete eradication of the infection, potentially causing it to return and be more difficult to treat. Choices A and B are not specific to amoxicillin and are general medication administration instructions. Choice C is not a common side effect of amoxicillin and does not require patient education.

5. A client has a new prescription for spironolactone. The client should be monitored for which of the following adverse effects?

A. Hyperkalemia
B. Hyponatremia
C. Hypokalemia
D. Hypercalcemia

Correct answer: A

Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia as an adverse effect. Hyperkalemia is characterized by elevated levels of potassium in the blood, which can be dangerous and lead to cardiac arrhythmias. Therefore, monitoring for signs and symptoms of hyperkalemia is crucial when a client is taking spironolactone. Choices B, C, and D are incorrect because spironolactone is not known to cause hyponatremia, hypokalemia, or hypercalcemia as adverse effects.
