  What does the nurse anticipate will be added to the losartan regimen for better control of this patient's hypertension? A) Candesartan (Atacand)
  B) Hydrochlorothiazide (Hyzaar)
  C) Captopril (Capoten)
  D) Antidiuretic hormone (ADH)

Answer to Question 1

B
Feedback:
When losartan therapy is started, maximal effects on blood pressure usually occur within 3 to 6 weeks. If losartan alone does not control blood pressure, a low dose of a diuretic may be added. A combination product of losartan and hydrochlorothiazide (Hyzaar) is available. Adding a second ARB such as candesartan or captopril would risk causing toxic adverse effects. ADH causes retention of water in the nephrons, which would further increase blood pressure.

Answer to Question 2

A
Feedback:
The surface area of a child is calculated using height and weight. It is the most accurate way to determine an appropriate dosage for that child. Age does not take into consideration variations in growth. Height alone does not take into account the mass of the child. Gestational age is simply a distracter.
