The patient will certainly recuperate under medical care.

The ANTONYM of the word RECUPERATE is:

The correct option is Degenerate.

Explanation:

To find the antonym (opposite meaning) of the word recuperate, let's first understand its meaning in the context of the sentence: "The patient will certainly recuperate under medical care."

1. Recuperate means to recover from illness, exertion, or injury; to regain health or strength. Therefore, the context implies the patient's health will improve under medical care.

2. Now, let us analyze the meaning of the given options to find the word with the opposite meaning:

• Resuscitate: To revive someone from unconsciousness or apparent death. This is related to recovery and is not an antonym.

• Reimburse: To repay someone who has spent money. This is financially related and irrelevant to health or recovery.

• Degenerate: To decline or deteriorate physically, mentally, or morally. In a medical context, when a patient's condition degenerates, their health worsens. This is the exact opposite of regaining health (recuperating).

• Convalesce: To recover one's health and strength gradually after an illness or medical treatment. This is a synonym of recuperate, not an antonym.

Thus, Degenerate is the correct antonym of Recuperate.
