Answer to Question 1

B
Kayexalate is a type of medicated enema used to treat clients with dangerously high serum po-tassium levels. This drug contains a resin that exchanges sodium ions for potassium ions in the large intestine.
Kayexalate enemas are not used to treat or prevent constipation.
Neomycin enemas, not Kayexalate enemas, may be used to reduce bacteria in the colon before diagnostic testing.
Kayexalate is not an antidiarrheal medication.

Answer to Question 2

D
The site most frequently recommended for heparin injections is the abdomen.
The scapular areas may be used for subcutaneous injections, but it is not a recommended site for heparin injections.
The vastus lateralis is used for intramuscular injections, not subcutaneous injections.
The posterior gluteal site is not recommended for heparin injections.
