A nurse is collecting data from a client who is taking propranolol. The nurse should monitor the client for which of the following adverse effects?

A. "Administer the medication early in the day.": Furosemide is a loop diuretic that increases urine output. Giving it early in the day helps prevent nocturia and sleep disturbances, ensuring the child remains well-rested while still receiving the therapeutic effect of fluid removal.

B. "Restrict foods that are high in potassium in your child's diet.": Furosemide can cause potassium loss, so the child’s diet should include potassium-rich foods rather than restrict them. Adequate potassium intake helps prevent hypokalemia, which can cause muscle weakness, arrhythmias, and other complications.

C. "Anticipate that your child will gain weight rapidly while taking this medication.": Furosemide typically reduces fluid retention, which may lead to weight loss or stabilization, not rapid weight gain. Rapid weight gain would indicate fluid accumulation or worsening heart failure, requiring further evaluation.

D. "Expect your child's urine to appear concentrated and dark yellow.": Furosemide increases urine output and dilutes the urine. Urine is more likely to be pale or clear rather than concentrated and dark yellow unless the child is dehydrated or not adequately hydrated.

A. The client's foot feels cooler than in the previous assessment: A cooler extremity following vascular surgery can indicate decreased perfusion, but temperature alone is a subjective and late indicator. It must be interpreted in conjunction with pulses, capillary refill, color, and pain. While concerning, it does not provide definitive evidence of acute graft compromise by itself.

B. The client's pedal pulse in the right foot is not palpable: Absence of a distal pedal pulse following a femoropopliteal bypass graft raises immediate concern for graft occlusion or acute arterial thrombosis. Patency of the graft is essential to restore blood flow to the lower extremity, and loss of pulse indicates potential ischemia.

C. The client's capillary refill time is 5 seconds in the toes: A prolonged capillary refill suggests impaired peripheral perfusion, but it is less specific than pulse assessment. Capillary refill can be influenced by environmental temperature and vasoconstriction. While abnormal, it is not as critical as the absence of a palpable pulse in evaluating graft function.

D. The client reports a pain level of 8 on a scale from 0 to 10: Postoperative pain is expected after a vascular surgical procedure and may be significant. However, pain must be correlated with other ischemic signs such as pulselessness, pallor, paresthesia, and paralysis to determine severity. Severe pain alone, without objective perfusion deficits, is not the most urgent finding.
