The nurse is initiating a 24-hour urine collection for a client with an indwelling urinary catheter. After emptying all the urine from the collection bag, which action is most important for the nurse to implement?

Choice A reason: Using a heating pad is contraindicated in Raynaud’s, as reduced sensation from vasospasm risks burns. Raynaud’s involves cold-triggered arteriolar constriction, reducing blood flow. Heat does not address vasospasm’s pathophysiology and may cause tissue damage, making this instruction inappropriate compared to cold protection strategies.

Choice B reason: Wearing gloves when handling cold items prevents vasospasm in Raynaud’s, where cold triggers arteriolar constriction, causing ischemia and pain. Protecting extremities maintains blood flow, preventing episodes. This directly addresses the disease’s pathophysiological trigger, making it the most effective instruction for managing Raynaud’s symptoms.

Choice C reason: Knee-high support stockings improve venous return, relevant for venous insufficiency, not Raynaud’s arterial vasospasm. Stockings do not prevent cold-induced vasoconstriction, the primary trigger. Gloves for cold exposure directly mitigate vasospastic episodes, making this instruction less effective for Raynaud’s disease management.

Choice D reason: Regular walking improves overall circulation but does not prevent Raynaud’s vasospastic episodes, triggered by cold or stress. While exercise supports vascular health, avoiding cold exposure with gloves is more targeted, directly reducing arteriolar constriction and ischemic symptoms, making walking a secondary recommendation.

Choice A reason: Taking two more readings confirms elevated BP, as a single reading may reflect technique errors or transient factors like pain, which increase sympathetic activity and vasoconstriction. Multiple readings ensure accuracy, critical for diagnosing hypertension and guiding intervention to prevent cardiovascular complications like stroke.

Choice B reason: Assigning a UAP to recheck BP in an hour delays assessment of potentially dangerous hypertension, which risks acute complications like myocardial ischemia. Immediate confirmation is needed, as elevated BP from norepinephrine release increases vascular resistance, making delayed rechecking inappropriate for urgent evaluation.

Choice C reason: Retaking BP in the opposite arm verifies accuracy, as differences may indicate arterial occlusion. Elevated BP increases catecholamine-driven vascular resistance. Measuring both arms rules out localized issues, ensuring reliable data to guide management of hypertension, critical to prevent end-organ damage like renal failure.

Choice D reason: Assessing apical-radial pulse deficit is relevant for atrial fibrillation, not directly for elevated BP. Hypertension results from increased vascular resistance, not pulse discrepancies. Confirming BP and assessing context are more immediate to determine urgency, making this less relevant than verifying readings or identifying triggers.

Choice E reason: Determining activity and feelings identifies transient BP elevation causes, like stress or exercise, which raise norepinephrine, increasing heart rate and vascular tone. This contextualizes the reading, differentiating situational from chronic hypertension, ensuring appropriate intervention to manage cardiovascular risk and guide further assessment.
