A nurse is caring for a client who has not voided since giving birth vaginally 10 hours ago. Which of the following actions should the nurse take?

Rationale:

A. Administer diuretics: The client's symptoms, moist lung sounds, bounding pulse, elevated blood pressure, and pitting edema indicate fluid volume overload. Administering prescribed diuretics is the priority intervention to rapidly reduce intravascular and interstitial fluid volume and relieve pulmonary congestion.

B. Limit the client's fluid intake: Fluid restriction helps manage ongoing fluid retention but does not address the immediate concern of volume overload. It is a supportive measure rather than the initial priority in acute decompensated heart failure.

C. Insert an indwelling urinary catheter: While catheterization may help monitor output, it does not treat the underlying fluid excess. Inserting a catheter without addressing the fluid accumulation first does not provide immediate symptom relief.

D. Place the client on a low-sodium diet: A low-sodium diet is important for long-term management of heart failure, but it does not provide the prompt fluid removal needed in this acute situation. Immediate diuresis is necessary to reduce cardiac workload and respiratory distress.

Rationale for correct choices:

• Administer oxygen at 2 L/min via nasal cannula: The client's oxygen saturation has dropped to 92% on room air, indicating mild hypoxia. Supplemental oxygen should be administered to improve myocardial oxygenation and reduce ischemia while further interventions are being prepared.
• Administer sublingual nitroglycerin: Nitroglycerin is a first-line medication for chest pain caused by suspected myocardial ischemia. It promotes vasodilation, reduces myocardial oxygen demand, and provides symptom relief. Administering it promptly can help prevent further cardiac damage.

Rationale for incorrect choices:

• Request a prescription for an increase in statin medication: Although the client has hyperlipidemia, increasing the statin dose is not an immediate priority during an acute chest pain episode. Lipid management is important long-term but does not address the acute ischemic event.
• Prepare the client for cardiac catheterization: Cardiac catheterization may eventually be necessary, but it is not the nurse’s first action. The priority is to stabilize the client’s symptoms (oxygenation and pain) before preparing for any invasive diagnostic or therapeutic procedure.
• Check a STAT cardiac troponin: Troponin has already been obtained and is within normal limits at this point. While serial troponins may be needed later, immediate nursing priorities focus on symptom relief and oxygenation rather than repeating the test right away.
• Request a prescription for a beta-blocker: Beta-blockers may be used in the treatment of suspected myocardial infarction to reduce heart rate and myocardial oxygen demand. However, their initiation typically follows pain relief, oxygenation, and diagnostic confirmation, not as the first nursing action.
