LPN Pharmacology

Correct Answer: A

Rationale: Elevated BNP levels are indicative of heart failure, which often causes fluid retention and weight gain. Taking daily weights and monitoring trends allows the nurse to assess for changes in fluid status. This intervention helps in evaluating the effectiveness of the treatment plan and identifying worsening heart failure symptoms early.

Correct Answer: D

Rationale: A slight increase in blood pressure without significant symptoms indicates that the client is tolerating the activity. In this scenario, a mild increase in blood pressure without other symptoms is a positive sign of tolerance to ambulation despite the underlying condition of bacterial endocarditis.

Correct Answer: D

Rationale: When assessing a venous stasis leg ulcer, the nurse should expect to note a brownish or 'brawny' appearance. This discoloration is often due to hemosiderin deposits. This characteristic finding helps differentiate venous stasis ulcers from other types of ulcers, making it crucial for accurate diagnosis and appropriate treatment.

Correct Answer: C

Rationale: Bibasilar crackles are abnormal lung sounds that indicate fluid accumulation in the lungs, a sign that left-sided heart failure is worsening. This finding suggests that the client's condition is deteriorating and requires prompt intervention to prevent further complications.

Correct Answer: A

Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects.
