Choice A reason: Client 4 should not be discharged. The client has COPD with thick, blood-tinged secretions and a very high fever, indicating a likely acute infection or COPD exacerbation. This places the client at risk for impaired gas exchange and respiratory failure. Based on Maslow’s Hierarchy, airway and breathing are top priorities, requiring continued inpatient care and monitoring. Choice B reason: Client 5 should not be discharged. The client shows clear signs of hemodynamic instability, including hypotension and tachycardia, consistent with significant dehydration and possible hypovolemia. Even with IV fluids running, circulation remains compromised. According to Maslow’s Hierarchy, maintaining circulation is a basic physiological need, necessitating ongoing hospital treatment. Choice C reason: Client 3 should be discharged. The client is four days post–total hip replacement, ambulating well with assistance, and actively participating in physical therapy without complications. Postoperative recovery is progressing as expected, and acute inpatient care is no longer required, making this client appropriate for discharge during a mass casualty event. Choice D reason: Client 1 should not be discharged. Recent chest pain relieved by nitroglycerin suggests possible myocardial ischemia. One day after admission is too soon to safely discharge without completing cardiac monitoring and evaluation. Cardiac stability is a critical physiological priority under Maslow’s framework. Choice E reason: Client 2 should be discharged. This is a stable preoperative client scheduled for elective bariatric surgery. During mass casualty events, elective procedures are postponed to preserve resources. The client has no acute medical needs and can safely be discharged and rescheduled later.
