What is the best way to determine if the patient has gastrointestinal complications from immobility?

A.Immobility does not increase systemic blood pressure; rather, it often leads to a decrease in vascular tone and a reduction in circulating blood volume. When a patient is sedentary, the baroreceptors become less sensitive to pressure changes. Consequently, when the patient stands, the body fails to provide the vasoconstriction necessary to maintain adequate blood pressure to the brain.

B.Orthostatic hypotension significantly increases the risk of falls rather than reducing it. The sudden drop in blood pressure upon standing leads to cerebral hypoperfusion, causing dizziness, syncope, and blurred vision. These symptoms compromise the patient's balance and stability, making them highly susceptible to accidental trips and injuries during initial ambulation attempts after periods of bed rest.

C.Cardiovascular function is impaired by prolonged immobility as the heart muscle begins to atrophy and the stroke volume decreases. The cardiovascular system requires regular gravitational and physical stress to maintain its efficiency in pumping blood against gravity. Without this stimulation, the heart must work harder at a higher heart rate to maintain cardiac output, representing a decline in overall function.

D.Cardiac deconditioning is the physiological process where the heart and peripheral vasculature lose efficiency due to a lack of physical activity. This leads to a decreased ability of the autonomic nervous system to rapidly constrict lower-extremity veins when a patient moves to an upright position. The resulting venous pooling reduces venous return and cardiac output, manifesting as a significant drop in blood pressure.

A.A client who has fallen represents an acute change in status and a high risk for physical injury, such as fractures or intracranial hemorrhage. According to nursing prioritization frameworks, actual safety threats and acute incidents take precedence over routine care or discomfort. The nurse must immediately assess the client for stability, neurological deficits, and musculoskeletal integrity to prevent further harm or complications.

B.Nausea in a postoperative client is a common clinical finding often related to anesthesia or opioid analgesics. While it causes significant distress and carries a risk of emesis and aspiration, it is generally considered a "stable" discomfort compared to an acute fall. The nurse should address this by administering prescribed antiemetics, but only after ensuring that no other clients are in immediate physical danger.

C.A beeping IV pump typically indicates an occlusion, an empty infusion bag, or a low battery. While this requires intervention to maintain the scheduled delivery of fluids or medications, it is a technical issue that does not pose an immediate threat to the client's life. Most IV pumps have a built-in "keep vein open" (KVO) rate or battery backup, allowing for a brief delay in troubleshooting.

D.Requesting a bedpan is a basic physiological need related to elimination. While timely assistance is necessary to maintain skin integrity and prevent the patient from attempting to ambulate unassisted (which could lead to a fall), it is a routine care task. In a prioritization scenario, the nurse must first attend to the client who has already experienced an injury or acute event.
