HESI Medical Surgical Practice Exam Quizlet

Correct Answer: B

Rationale: In this scenario, the client is 55 years old with a history of 'heart trouble,' which necessitates a recent ECG before surgery as per hospital policy. The nurse should prioritize patient safety and adhere to the protocol by arranging for an ECG to be performed immediately. Option A is not the best initial action as the focus should be on obtaining the necessary test first. Option C is not the immediate action required, and option D is premature without obtaining the necessary ECG first.

Correct Answer: C

Rationale: The correct answer is C: Purulent sputum. Corticosteroids can suppress the immune system, increasing the risk of infections. Purulent sputum suggests a possible respiratory infection, which can rapidly progress and lead to complications, making it the most concerning finding. Choice A, a white blood count of 10,000/mm�, is within the normal range and not typically a cause for immediate concern. Choice B, a serum glucose level of 115 mg/dL, is also normal and not directly related to corticosteroid use. Choice D, excessive hunger, is a common side effect of corticosteroids but is not as concerning as a sign of infection indicated by purulent sputum.

Correct Answer: A

Rationale: The priority nursing diagnosis for a client on a mechanical ventilator receiving vecuronium bromide is 'Impaired communication related to paralysis of skeletal muscles.' Vecuronium is a skeletal muscle relaxant that causes diaphragmatic paralysis, leading to the inability of the client to communicate effectively. This is a crucial nursing concern as it impacts the client's ability to express needs and participate in care. Option B 'High risk for infection related to increased intracranial pressure' is not the priority in this scenario as the client's condition is related to the effects of the medication and mechanical ventilation, not directly to increased intracranial pressure. Option C 'Potential for injury related to impaired lung expansion' is important but not the priority over impaired communication. Option D 'Social isolation related to inability to communicate' is not the priority nursing diagnosis in this situation as it focuses more on psychosocial aspects rather than the immediate physiological concern of communication impairment.

Correct Answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

Correct Answer: D

Rationale: Being direct and explaining to the client that the test requires him to be NPO, is the most therapeutic statement because the nurse is responding to the client's question and providing him the reason why.
