Brief Introduction: This scenario requires applying the airway, breathing, circulation framework to prioritize care. Clinical knowledge of hemodynamic stability and life-threatening complications like hypovolemic shock is necessary to differentiate urgent physiological needs from routine preoperative tasks or non-urgent symptoms like constipation. Choice A rationale A blood pressure of 88/48 mm Hg indicates significant hypotension, suggesting hemorrhage or shock in a postoperative client. Normal systolic pressure is 90 to 120 mm Hg. This client requires immediate intervention to maintain organ perfusion and stability. Choice B rationale Constipation is a common side effect of opioid analgesics due to decreased gastrointestinal motility. While uncomfortable, it is not life-threatening and does not require immediate assessment compared to hemodynamic instability. It can be managed after urgent clients are stabilized. Choice C rationale Ensuring a preoperative client signs a consent form is a vital legal and administrative task. However, this is a psychosocial and procedural need that falls lower on the clinical priority list than a client with unstable vital signs. Choice D rationale A temperature of 38.9 degrees C (102 degrees F) indicates a fever, which is expected with a wound infection. While requiring attention, it is less critical than profound hypotension. Normal body temperature is approximately 37 degrees C (98.6 degrees F).
