The question is incomplete.

The complete question is:

A client comes to the physician's office for a follow-up visit 4 weeks after suffering a myocardial infarction (MI). The nurse takes this opportunity to evaluate the client's knowledge of the ordered cardiac rehabilitation program. Which evaluation statement suggests that the client needs more instruction?

A. "Client performs relaxation exercises three times per day to reduce stress."

B. "Client walks 4 miles in 1 hour every day."

C. "Client's 24-hour dietary recall reveals low intake of fat and cholesterol."

D. "Client verbalizes an understanding of the need to seek emergency help if his heart rate increases markedly while at rest."

Answer:

Option B. "Client walks 4 miles in 1 hour every day."

Explanation:

A myocardial infarction (MI) or heart attack occurs when there is no sufficient blood supply to the heart due to less blood flow which causes damage to the heart muscle.

After 4 weeks of MI, a client will be provoded more instruction on the basis that " Client walks 4 miles in 1 hour". The physician should suggest him to walk for 2 miles in less than 1 hour as walking 4 miles in 1 hour can cause another MI due to increase in the oxygen demand of heart.

Therefore, client should be provided precautions regarding appropriate exercise. Client will be notified about the cardiac rehabilitation program that include relaxation exercises, to follow low-cholesterol diet, and seeking emergency help if heart rate increases suddenly.

Thus, the correct option is B.
