Final answer:
Cardene I.V. is indicated for the treatment of hypertension when oral therapy is not feasible. It is not specifically indicated for prolonged blood pressure control, direct treatment of stroke or end organ damage, or protection against abrupt beta blocker withdrawal.
Step-by-step explanation:
Cardene I.V. is a medication primarily used to manage certain cardiovascular conditions. It is utilized for the treatment of hypertension when oral therapy is not feasible or practicable, making it an important drug in acute care settings where prompt blood pressure control is necessary. While it's true that treating hypertension is crucial for preventing complications such as stroke and end organ damage, and that sympatholytic drugs like beta blockers can protect against certain cardiovascular risks, Cardene I.V.'s specific indication does not include prolonged control of blood pressure unrelated to acute episodes, direct stroke or end organ damage treatment, or protection against abrupt beta blocker withdrawal.
The correct indication for the use of Cardene I.V. thus is b) Treatment of hypertension when oral therapy is not feasible.
