A nurse is caring for a client who has angina and reports a feeling of heaviness in the chest while ambulating in the hall. Which of the following actions should the nurse take first?

Rationale for Correct Choices

• Evaluating the fetal heart rate tracing: The client presents with severe preeclampsia, as indicated by hypertension (166/110 mm Hg), 3+ proteinuria, and hyperreflexia. The priority is to assess fetal well-being since decreased fetal movement and maternal hypertension can compromise placental perfusion, placing the fetus at risk for hypoxia or distress.

• Administering magnesium sulfate IV: Once fetal assessment confirms stability, magnesium sulfate should be initiated to prevent eclamptic seizures. This medication stabilizes the central nervous system by reducing neuromuscular excitability and cerebral irritation associated with severe preeclampsia.

Rationale for Incorrect Choices

• Administering acetaminophen PO: The client already reported that acetaminophen was ineffective for headache relief. The headache is a sign of severe preeclampsia, not a benign pain complaint, so administering more acetaminophen does not address the underlying pathology.

• Obtaining 24-hour urine collection: While important for confirming the degree of proteinuria, this action is not an immediate priority. Stabilizing maternal and fetal conditions takes precedence over diagnostic collection.

• Inserting an indwelling urinary catheter: The catheter is required for strict intake and output monitoring during magnesium therapy, but it is not performed before ensuring fetal stability and initiating seizure prophylaxis.

• Administering betamethasone IM: Betamethasone promotes fetal lung maturity, which is appropriate in preterm conditions; however, it is not the immediate priority. Seizure prevention and fetal assessment are more urgent interventions at this stage.

Rationale:
A. Medication reconciliation involves reviewing all medications the client was taking at home and comparing them with the prescriptions ordered on admission. This process helps identify discrepancies, prevent omissions, duplications, or potential interactions, and ensures continuity of care.

B. Comparing a standard list of medications for a condition is not part of medication reconciliation because it may not reflect the individual client’s needs, allergies, or previous therapy. The focus should be on the client’s actual home medications.

C. This step refers to the “three checks” of medication administration, which is different from the initial reconciliation process. Reconciliation focuses on matching home medications with admission orders, not verifying labels prior to each dose.

D. While checking for allergies is a critical safety step, it is only one component of safe medication administration. Medication reconciliation is broader, ensuring that all home medications are considered and that any changes or omissions are intentional and documented.
