Answer :
Final answer:
For a patient with renal insufficiency, a decreased dosage of cardiac medication is typically appropriate to prevent potential drug toxicity. The patient's renal condition prevents normal drug excretion, thus necessitating dosage adjustment.
Explanation:
The subject of this question pertains to medicine, specifically in the area of pharmacology and patient care. In this situation, an older client with renal insufficiency is preparing to receive a cardiac medication. Due to their renal insufficiency, the patient's ability to excrete drugs in their urine may decrease. Hence, the dosage of medication must be adjusted accordingly to prevent potential drug toxicity. Therefore, the nurse is most likely to administer a decreased dosage (option 1) of the cardiac medication. This reduced dose ensures that the drug is effective but doesn't build up to harmful levels in the body due to the kidneys' reduced function.
