[Metfan725]

The patient 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?
 
  1. Hydrochlorothiazide (HydroDIURIL) enhances kidney function causing you to urinate more and that decreases your blood pressure.
  2. Hydrochlorothiazide (HydroDIURIL) decreases the fluid in your bloodstream and this lowers your blood pressure.
  3. Hydrochlorothiazide (HydroDIURIL) dilates your blood vessels so you urinate more and your blood pressure decreases.
  4. Hydrochlorothiazide (HydroDIURIL) increases your heart rate; this pumps blood faster to your kidneys so you urinate more and your blood pressure decreases.

Question 2

The nurse is caring for a patient with a pH of 7.32. Which medications would be appropriate to administer to a patient with this condition?
 
  1. Oral bicarbonate
  2. Sodium chloride
  3. Citrate salts
  4. Potassium chloride
  5. Ammonium chloride

Answer to Question 1

Correct Answer: 2
Rationale: Blood volume is one of the three factors influencing blood pressure. Diuretics like hydrochlorothiazide (HydroDIURIL) decrease blood pressure by decreasing total blood volume. Hydrochlorothiazide (HydroDIURIL) does not increase heart rate. Hydrochlorothiazide (HydroDIURIL) does not dilate blood vessels. Hydrochlorothiazide (HydroDIURIL) does not enhance kidney function.

Answer to Question 2

Correct Answer: 1,3
Rationale 1: Oral bicarbonate is an agent used to treat acidosis.
Rationale 2: Sodium chloride is an agent used to treat alkalosis.
Rationale 3: Citrate salts are an agent used to treat acidosis.
Rationale 4: Potassium chloride is an agent used to treat alkalosis.
Rationale 5: Potassium chloride is an agent used to treat alkalosis.
