The nursing problem of activity Intolerance related to impaired ventricular function is made for a client with myocarditis. Which outcome in the plan of care would reflect resolution of this issue? The client will:
ambulate in the hall 3 times daily without shortness of breath.
have an increase in systolic blood pressure of 20 mmHg during activity.
decrease weight from 150 lbs. (68.2 kg.) to 148 lbs. (67.3 kg.) in five days.
verbalize the signs and symptoms of worsening heart failure by discharge.
The Correct Answer is A
A. ambulate in the hall 3 times daily without shortness of breath: This directly reflects improved tolerance to activity, the central focus of the nursing diagnosis. Being able to ambulate without dyspnea indicates better cardiac output and ventricular function, marking resolution of the identified problem.
B. have an increase in systolic blood pressure of 20 mmHg during activity: A rise in systolic pressure may occur with exertion, but it does not necessarily indicate improved activity tolerance. In fact, an exaggerated BP response could indicate the heart is working harder than it should to meet the demands, suggesting poor cardiovascular adaptation to exercise.
C. decrease weight from 150 lbs. (68.2 kg.) to 148 lbs. (67.3 kg.) in five days: A slight weight reduction may reflect decreased fluid retention, but this outcome is more relevant to volume status and fluid balance than to resolving activity intolerance specifically.
D. verbalize the signs and symptoms of worsening heart failure by discharge:
While important for client education and self-management, this outcome relates to knowledge rather than physical tolerance to activity. It does not directly measure resolution of activity intolerance.

Correct Answer is D
Explanation
A. Increase the pacemaker sensitivity: Adjusting pacemaker sensitivity is a technical function typically managed by a cardiologist or device technician. There is no indication from the information provided that the pacemaker is under- or over-sensing, so no adjustment is warranted.
B. Document that the pacemaker is regular: While the pacemaker may be functioning regularly, this statement is vague and does not accurately describe the observed pacing activity. The key observation is the spike occurring before the P wave, which requires more specific documentation.
C. Set the pacemaker to the asynchronous mode: Asynchronous pacing means the pacemaker fires at a set rate regardless of the patient's intrinsic rhythm and is generally reserved for specific situations such as during surgery or when interference with sensing is suspected. There is no evidence of pacemaker malfunction or need to override sensing in this scenario.
D. Document that the atria are being paced: A pacemaker spike immediately before the P wave indicates atrial pacing. This means the pacemaker is stimulating the atria, leading to atrial depolarization. This is the appropriate interpretation and should be documented clearly.
Correct Answer is ["0.5"]
Explanation
Convert milligrams to micrograms.
1 mg = 1000 mcg.
0.05 mg × 1000 mcg/mg = 50 mcg
Desired dose = 25 mcg
Available dose = 50 mcg/tablet
Calculate the number of tablets.
Number of tablets = Desired dose / Available dose per tablet
= 25 mcg / 50 mcg/tablet
= 0.5
The nurse should administer 0.5 tablet.
