Final answer:
The correct nursing implications for administering Procardia (nifedipine) include regular monitoring of blood pressure and heart rate, as the medication affects the cardiovascular system by relaxing the blood vessels and lowering blood pressure.
Step-by-step explanation:
The nursing implications for Procardia (nifedipine) involve careful patient monitoring due to its effects as a calcium channel blocker, one of its primary uses is the treatment of hypertension. Procardia works by relaxing the blood vessels, which reduces the heart's workload and helps to lower blood pressure. It does not impact blood sugar levels directly, so option (a) is incorrect. Nifedipine is administered orally, not via intramuscular injection, making option (b) incorrect too. The most important nursing implications are to monitor blood pressure and heart rate regularly (option c) to assess the effectiveness of the medication and to adjust the dosage if necessary. Encouraging a diet high in vitamin K (option d) is not associated with nifedipine, so this advice would also be incorrect.
