The nurse is providing education to a client on ways to prevent the development of a pulmonary embolism. Which of the following statements would require further teaching?

A. Eating six small meals a day prevents excessive oxygen demand during digestion and reduces bloating, which can impair breathing.
B. Protein intake is important, but it does not directly impact intravascular hydrostatic pressure in a way that would help with COPD and right-sided heart failure.
C. While adequate hydration is necessary, excessive fluid intake can worsen right-sided heart failure by increasing fluid retention and edema.
D. Lying down after eating can worsen dyspnea and lead to reflux, which is not advisable for COPD patients.

A. Vital signs . The client has tachycardia (HR 138/min) and tachypnea (RR 28/min), which may indicate worsening heart failure or fluid overload. The low blood pressure (96/75 mmHg) is also concerning, especially with rapid ventricular response (RVR).
B. Respiratory assessment . The presence of a frequent cough with pink-tinged sputum suggests pulmonary congestion or pulmonary edema, a sign of worsening left-sided heart failure.
C. Renal function . The BUN of 28 mg/dL (elevated) and creatinine of 1.5 mg/dL (borderline high) suggest possible kidney impairment due to decreased cardiac output and poor perfusion.
D. Cardiac enzymes . The client denies chest pain or discomfort, so cardiac enzymes are not the immediate priority.
E. BNP (B-type natriuretic peptide) . BNP is a key marker of heart failure severity and helps guide treatment decisions.
F. ECG results . The atrial fibrillation with RVR increases the risk of hemodynamic instability and potential thromboembolic events, requiring urgent intervention.
G. Neurologic status . The client is alert, oriented, and following commands, so no immediate neurologic concerns are present.
