B. increase the amount of thyroid-stimulating hormone circulating in
the blood.
C. increase the amount of T4 and decrease the amount of T3 produced
by the thyroid.
D. inhibit synthesis of T3 and T4 by the thyroid gland.
D. PTU is an adjunct therapy used to control hyperthyroidism by
inhibiting production of thyroid hormones. It is often prescribed in prep
for thyroidectomy or radioactive iodine therapy
2) A female client with RA takes ibuprofen (motrin) 600mg PO 4xday.

D. Heart Failure
Dobutamine is a beta-1 adrenergic agonist that is indicated for short term
use in cardiac decompensation or heart failure (D) related to reduced
cardiac contractility due to organic heart disease or cardiac surgical
procedures. Alpha and beta adrenergic agonists, such as epinephrine and
dopamine, are sympathomimetics used in the treatment of shock (A).
Other selective beta-2 adrenergic agonists, such as terbutaline and
isoproterenol, are indicated in the treatment of asthma (B). Although
dobutamine improves cardiac output, it is not used to treat hypotension
(C).

client about diet modifications?
A) Do not add salt to foods during preparation.
B) Refrain for eating foods high in potassium.
C) Restrict fluid intake to 1000 ml per day.
D) Increase intake of milk and milk products.
B.
Spironolactone (Aldactone), an aldosterone antagonist, is a potassium-
sparing diuretic, so a diet high in potassium should be avoided (B),
including potassium salt substitutes, which can lead to hyperkalemia.
Although (A) is a common diet modification in heart failure, the risk of
hyperkalemia is more important with Aldactone. Restriction of fluids (C)
or increasing milk and milk products (D) are not indicated with this
prescription.
