A patient is prescribed metoprolol in the treatment of stable angina.
What is the best outcome measure of decreased cardiac workload due to metoprolol for the nurse to evaluate?
Patient's heart rate is 62 and regular.
Patient is able to lie flat without reporting difficulty breathing.
Patient does not report dyspnea after climbing one flight of stairs.
Patient has weight loss of 3 lbs (1.4 kg) over 2 weeks.
The Correct Answer is A
Choice A rationale
Metoprolol decreases cardiac workload by reducing heart rate and myocardial oxygen demand. A heart rate of 62 is within normal limits, demonstrating effective beta-blocker action and improved cardiac efficiency.
Choice B rationale
Lying flat without difficulty breathing reflects improved respiratory status, which is more related to pulmonary management, not directly indicative of reduced cardiac workload or beta-blocker efficacy.
Choice C rationale
Absence of dyspnea after climbing stairs suggests improved physical fitness but does not directly measure the cardiac effects of metoprolol, which targets heart rate reduction and myocardial oxygen use.
Choice D rationale
Weight loss is related to overall health improvement or dietary changes rather than specific effects of metoprolol, which primarily impacts heart rate and cardiac oxygen consumption.

Correct Answer is B
Explanation
Choice A rationale
Checking serum drug levels provides insight into compliance and effectiveness but doesn’t address immediate seizure cessation, prioritizing treatment over diagnostic assessment.
Choice B rationale
Administering lorazepam IV halts seizure activity quickly by enhancing GABA activity, calming neuronal excitation, and stabilizing the patient’s condition, reducing potential complications.
Choice C rationale
Monitoring vitals like blood pressure and heart rate is essential but doesn’t directly address convulsive activity, which requires immediate pharmacological intervention to prevent status epilepticus progression. .
