A nurse is collecting data from a client prior to administering nifedipine. For which of the following findings should the nurse contact the provider?.

The correct answer is choice B. Peripheral edema of the ankles. Choice A rationale: A blood pressure of 148/94 mm Hg is elevated, but it is not an immediate contraindication for administering nifedipine. Nifedipine is often used to treat hypertension. Choice B rationale: Peripheral edema is a common side effect of nifedipine and can indicate worsening fluid retention. The nurse should contact the provider to assess the need for adjusting the medication or implementing additional interventions. Choice C rationale: A heart rate of 66/min is within the normal range (60-100/min) and does not require immediate action before administering nifedipine. Choice D rationale: An increased alkaline phosphatase level can indicate liver or bone disease, but it is not directly related to the administration of nifedipine. However, it should be monitored and discussed with the provider.
