An 80-year-old client tells the nurse that he has been dizzy since starting to take an herbal remedy for arthritis in addition to prescribed medications. Which of the following effects is this client experiencing?

Correct Answer: A

Rationale: The correct answer is A: Polypharmacy. Polypharmacy refers to the use of multiple medications concurrently, which can lead to drug-drug interactions causing adverse effects like dizziness. In this case, the client's dizziness is likely due to the combination of the herbal remedy for arthritis with prescribed medications. B: Sleep disorder is incorrect because dizziness is not typically associated with sleep disorders. C: Cascade iatrogenesis is incorrect as it refers to a sequence of adverse events resulting from medical treatment, not specifically related to dizziness. D: Fluid volume overload is incorrect as it is characterized by symptoms like edema and shortness of breath, not dizziness.

Correct Answer: C

Rationale: The correct answer is C: Check pulse with a doppler. This is the most appropriate action as using a doppler can help detect the pulse accurately when palpation is difficult. Rechecking in 1 hour (B) is not necessary as immediate action is required. Recording the finding (A) without further assessment may lead to missed critical information. Notifying the healthcare provider (D) at this stage is premature as further assessment is needed before involving the provider.

Correct Answer: A

Rationale: Correct Answer: A (0.5 tablets) Rationale: 1. The ordered dose is 12.5 mg. 2. The available tablets are 25 mg. 3. Divide the ordered dose by the tablet strength: 12.5 mg / 25 mg = 0.5 tablets. 4. The nurse administers 0.5 tablets to achieve the prescribed dose accurately. Summary: - Option B (1 tablet) is incorrect as it would give double the prescribed dose. - Option C (1.5 tablets) is incorrect as it would exceed the prescribed dose. - Option D (2 tablets) is incorrect as it would give four times the prescribed dose.

Correct Answer: C

Rationale: The DNP focuses on advanced clinical practice, leadership, and evidence-based decision-making, distinguishing it from research-focused PhD programs.

Correct Answer: D

Rationale: Prescriptive theories offer specific recommendations and interventions to achieve nursing goals, unlike descriptive or developmental theories.
