The nurse is to administer heparin to a client who weighs 90 pounds. Heparin is ordered as 10,000 units/100mL. The nurse needs to administer a bolus of 40units/kg. How many units would the nurse administer? (Round to the nearest tenth)

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.

A. Ascites is more commonly associated with right-sided heart failure. Right-sided failure leads to systemic congestion, causing fluid accumulation in the abdomen.
B. Edema in the legs and feet is a symptom of right-sided heart failure. Left-sided failure primarily affects the lungs, while right-sided failure leads to peripheral edema.
C. Crackles in the lungs are expected in left-sided heart failure. Pulmonary congestion results from blood backing up into the lungs, leading to fluid accumulation in the alveoli.
D. Confusion can occur due to decreased cardiac output and poor oxygenation to the brain. Clients with severe heart failure may experience cognitive changes or altered mental status.
E. Exertional dyspnea is a hallmark of left-sided heart failure. The inability of the left ventricle to pump effectively leads to pulmonary congestion, making breathing difficult during physical activity.
