1. What does it mean when a medication has a half-life?

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.

2. A nurse in a clinic is caring for a group of clients. The nurse should contact the provider about a potential contraindication to a medication for which of the following clients? (Select all that apply.)

Correct answer: B

Rationale: Prednisone, a glucocorticoid, should not be taken by a client who has a possible systemic fungal infection as it can worsen the infection. This combination can suppress the immune response, allowing the fungal infection to proliferate. Therefore, the nurse should contact the provider regarding this potential contraindication to medication. The other options do not present a contraindication related to the medication interactions described in the question.

3. A client is prescribed Diltiazem. Which of the following findings should the nurse monitor?

Correct answer: B

Rationale: Diltiazem is a calcium channel blocker that can cause bradycardia as an adverse effect due to its negative chronotropic properties, slowing down the heart rate. Therefore, the nurse should monitor the client for signs of bradycardia by regularly assessing the heart rate to prevent potential complications. Monitoring for tachycardia (choice A) is incorrect as diltiazem typically does not cause tachycardia. Hypertension (choice C) is not a typical finding to monitor for with diltiazem use. Hyperkalemia (choice D) is not directly associated with diltiazem administration.

4. During an assessment, a male client who has recently started taking Haloperidol is displaying certain symptoms. Which of the following findings should the nurse prioritize in reporting to the provider?

Correct answer: B

Rationale: Neck spasms are indicative of acute dystonia, a serious side effect of Haloperidol that requires urgent intervention. Immediate reporting to the provider is crucial to address this potentially harmful condition and ensure the client's safety. Shuffling gait, drowsiness, and impotence are important to monitor but do not pose the same level of immediate risk as acute dystonia. Acute dystonia can lead to serious complications if not promptly treated, making it the priority in this scenario.

5. A healthcare professional is preparing to administer IV Vancomycin to a client who has a systemic infection. Which of the following actions should the healthcare professional take?

Correct answer: D

Rationale: The correct action for the healthcare professional is to monitor the client for Red Man Syndrome. Red Man Syndrome is a common adverse reaction to Vancomycin characterized by flushing, rash, and hypotension. It is important to monitor the client for these symptoms to intervene promptly if they occur.
