Final answer:
The nurse may question administering the calcium channel blocker if the client's blood pressure is low.
Step-by-step explanation:
The nurse would likely question administering the calcium channel blocker to the client diagnosed with a MI if the client's BP is 90/62.
In patients with a myocardial infarction (MI), maintaining blood pressure within a normal range is crucial for promoting adequate perfusion to the heart and other organs. A blood pressure reading of 90/62 may indicate hypotension, which could worsen the client's condition if the calcium channel blocker further lowers their blood pressure.
Therefore, it would be important for the nurse to consult with the healthcare provider and determine if an alternative medication or additional interventions are necessary.
