Which order for potassium (KCl) would the nurse question? (Select all that apply.)
 
  a. NS with 20 mEq KCl to start after patient voids
  b. NS with 60 mEq KCl for a patient with a serum potassium of 3.2 mEq/L
  c. K-Dur, 1 tablet daily for a patient in di-abetic ketoacidosis
  d. K-Dur, 1 tablet with a full glass of water
  e. Potassium chloride, 10 mEq rapid IV push

Question 2

A nurse provides teaching to a group of nursing students about the risks and benefits of hormone therapy (HT), including estrogen therapy (ET) and combination estrogen/progestin therapy (EPT).
 
  Which statement by a student indicates understanding of the teaching? a. ET can provide protection against coro-nary heart disease and reverse osteoporo-sis.
  b. EPT is generally safer than ET, especially in women who have undergone hysterectomies.
  c. In women with established coronary heart disease, EPT can protect against myocardial infarction.
  d. Principle benefits of ET are suppression of menopausal symptoms and prevention of bone loss.

Answer to Question 1

B, C, E
Patients receiving potassium should not receive potassium in solution diluted at more than 40 mEq/L. Diabetic ketoacidosis causes decreased cellular uptake of potassium, and patients in whom acidosis is present should also receive sodium bicarbonate if they need potassium. IV po-tassium should not be infused faster than 10 mEq/hr. NS with 20 mEq KCl is an appropriate so-lution for a patient with intact renal function. Oral potassium should be given with a full glass of water to minimize gastrointestinal (GI) effects.

Answer to Question 2

D
ET can be used to suppress menopausal symptoms and to prevent osteoporosis, but it carries risks of breast cancer and stroke, while conferring no preventive benefit for coronary heart disease. ET does not reverse osteoporosis but may help prevent it. EPT is not safer than ET; progestins appear to increase the risk of breast cancer. EPT does not prevent myocardial infarction in patients with coronary heart disease.
