Which action will be included in the plan of care when the nurse is caring for a patient who is receiving nicardipine(Cardene) to treat a hypertensive emergency?

Correct Answer: D

Rationale: Frequent monitoring of BP is needed when the patient is receiving rapid-acting IV antihypertensive medications. This can be most easily accomplished with an automated BP machine or arterial line. The patient will require frequent assessments, so allowing 6 to 8 hours of undisturbed sleep is not appropriate. When patients are receiving IV vasodilators, bed rest is maintained to prevent decreased cerebral perfusion and fainting. There is no indication that this patient is nauseated or at risk for aspiration, so an NPO status is unnecessary.

Correct Answer: D

Rationale: The prevalence of uncontrolled hypertension varies by ethnicity, with Hispanics and African Americans having the highest prevalence at approximately $63 \%$ and $57 \%$, respectively.
