Pharmaceuticals Used in the Treatment of Hypertension Quiz


Questions and Answers
  • 1. 
    The client receives hydrochlorothiazide (HydroDIURIL). He tells the nurse he is urinating a lot and questions how this drug affects his blood pressure. What is the best response by the nurse?
    • A. 

      “Hydrochlorothiazide (HydroDIURIL) dilates your blood vessels so you urinate more and your blood pressure decreases.”

    • B. 

      “Hydrochlorothiazide (HydroDIURIL) decreases the fluid in your bloodstream and this lowers your blood pressure.”

    • C. 

      “Hydrochlorothiazide (HydroDIURIL) enhances kidney function causing you to urinate more and that decreases your blood pressure.”

    • D. 

      “Hydrochlorothiazide (HydroDIURIL) increases your heart rate; this pumps blood faster to your kidneys so you urinate more and your blood pressure decreases.”
