HESI 799 RN Exit Exam Capstone

Correct Answer: C

Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

Correct Answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

Correct Answer: C

Rationale: The best intervention for a client with dysphagia experiencing difficulty swallowing medications is to consult with the healthcare provider about switching to liquid medications. Liquid medications are often easier to swallow and can reduce the risk of choking and aspiration in clients with dysphagia. Crushing medications can alter their effectiveness, encouraging the client to drink water may not be sufficient, and offering soft foods is not directly related to improving medication swallowing.

Correct Answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

Correct Answer: B

Rationale: Vertigo is the primary symptom of Meniere's disease and can lead to falls and other injuries. Ensuring safety and addressing the risk of injury is the nurse's top priority. While social isolation and impaired hearing are significant concerns associated with Meniere's disease, the immediate danger of falls due to vertigo takes precedence in the plan of care. Impaired verbal communication, although important, is not as urgent as preventing injuries caused by vertigo.
