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. Pale and a 24-hr fluid deficit of 30 mL: Mild pallor and a small fluid deficit are not uncommon in early stages of illness and may not require immediate intervention. However, more serious signs of dehydration would take priority for reporting.

B. Temperature 38° C (100.4° F) and pulse rate 124/min: These are within expected limits for an infant with mild infection or fever. While they should be monitored, they are not urgent indicators of severe complications from gastroenteritis.

C. Decreased appetite and irritability: These are common symptoms in infants with viral illnesses, including gastroenteritis. Although they affect comfort and feeding, they are not necessarily indicators of serious fluid or electrolyte imbalance.

D. Sunken fontanels and dry mucous membranes: These are clinical signs of moderate to severe dehydration, which is a serious complication of gastroenteritis in infants. These findings must be reported promptly for urgent intervention to prevent further deterioration.

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.
