A nurse is planning care for a client who has preeclampsia with severe features and is receiving magnesium sulfate via continuous IV infusion. Which of the following interventions should the nurse plan to include?

• Heart failure: The client’s new exertional dyspnea, fatigue, and bilateral crackles indicate fluid backing up into the lungs, which is typical in heart failure. The increase in heart rate and blood pressure suggests rising cardiac workload.. Pulmonary crackles especially point toward impaired left ventricular function leading to congestion.

• Heart and lung sounds: The presence of bilateral crackles is a key sign of pulmonary congestion associated with worsening heart function. Coupled with tachycardia and exertional dyspnea, these findings strongly support a cardiac cause rather than respiratory or infectious processes. These auscultatory findings of S3 directly link the symptoms to the underlying condition.

Rationale for incorrect choices

• Urinary tract infection: The client reports normal voiding, no burning, frequency, or urgency, and no systemic symptoms such as fever. Vital signs do not show abnormalities commonly associated with infection. The respiratory findings are entirely unrelated to urinary tract concerns, making this explanation unlikely. No urinary data indicate infection or inflammation.

• Fluid volume deficit: Typical signs of deficit—hypotension, tachycardia with weak pulse, dry mucous membranes, or decreased output—are not present. Instead, the client has hypertension and crackles, indicating volume overload rather than deficit. Fluid in the lungs suggests retention, not loss, ruling out this condition. The clinical picture supports congestion instead of dehydration.

• Atrial fibrillation: The ECG shows sinus tachycardia rather than an irregular rhythm, which is the hallmark of atrial fibrillation. P waves remain organized, indicating maintained electrical conduction through the atria. While tachycardia is present, it appears compensatory, not dysrhythmic. The clinical symptoms correlate more with heart failure than with atrial arrhythmia.

• 12-lead ECG findings: Although the client has sinus tachycardia, this finding is nonspecific and does not directly identify heart failure. The rhythm is regular and lacks features that point to arrhythmias or acute ischemia. Tachycardia can result from many conditions, making it insufficient evidence for diagnosis. The abnormal heart and lung sounds offer stronger, more specific clinical indicators.

• Urinary report: There are no urinary abnormalities or complaints to suggest changes in renal status. The client is voiding normally and without discomfort, making urinary data irrelevant to the current condition. Nothing in the urinary report supports a cardiovascular diagnosis. Therefore, it does not provide evidence of heart failure.

• Blood pressure: Although the blood pressure is elevated, hypertension alone does not confirm heart failure because it can result from multiple factors. Blood pressure changes provide supporting context but not primary evidence of fluid overload. The presence of crackles gives more direct information about pulmonary congestion.

A. Beef liver: Beef liver is high in cholesterol and saturated fat, which can increase serum cholesterol levels. Consuming liver is not recommended for clients managing hypercholesterolemia because it can exacerbate lipid abnormalities.

B. Egg whites: Egg whites contain protein without cholesterol or saturated fat. They are a heart-healthy alternative to whole eggs and can be safely included in a diet aimed at lowering or managing cholesterol levels.

C. Steamed clams: While clams are low in fat, they do contain some dietary cholesterol. In clients needing to strictly manage cholesterol intake, they should be consumed in moderation rather than emphasized as a primary protein source.

D. Broiled lobster: Lobster contains moderate amounts of cholesterol and should be limited in a cholesterol-lowering diet. Although broiling reduces added fats, the natural cholesterol content makes it less ideal than egg whites for daily consumption.
