The nurse is caring for a 70-year-old who uses hydrochlorothiazide(HydroDIURIL) and enalapril(Norvasc), but whose self-monitored blood pressure(BP) continues to be elevated. Which patient information may indicate a need for a change?

Correct Answer: D

Rationale: Because use of nonsteroidal antiinflammatory drugs(NSAIDs) can prevent adequate BP control, the patient may need to avoid the use of ibuprofen. A multivitamin tablet will help supply vitamin D, which may help lower BP. BP decreases while sleeping, so self-monitoring early in the morning will result in obtaining pressures that are at their lowest. The patient's alcohol intake is not excessive.

Correct Answer: A

Rationale: Nitric oxide inhibits gene transcription for endothelin-1 secretion through various signaling pathways.

Correct Answer: D

Rationale: The largest drop in energy actually occurs across the arterioles, not the precapillary sphincters.

Correct Answer: D

Rationale: The cardiac cycle encompasses all the events associated with one complete heartbeat, including systole and diastole of both atria and ventricles.
