HESI 799 RN Exit Exam Capstone

Correct Answer: B

Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.

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: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

Correct Answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

Correct Answer: A

Rationale: Excessive bruising and elevated blood glucose are common symptoms of Cushing's syndrome. The nurse should first check the client's blood glucose level to assess and address the hyperglycemia promptly. Administering insulin or IV fluids would be premature without knowing the current blood glucose level. Checking the skin for bruising, although important for overall assessment, does not address the immediate concern of elevated blood glucose.
