A patient with diarrhea has been prescribed methylcellulose (Citrucel). The patient asks the nurse, I thought this was for constipation. Why am I getting it? Select the most appropriate response from the nurse.
 
  a. Methylcellulose adds bulk to the stool to firm it up.
  b. Methylcellulose acts by reducing the volume of diarrhea.
  c. Methylcellulose reduces intestinal motility, slowing intestinal transit.
  d. Methylcellulose stimulates the bowel to eliminate the diarrhea, leaving only formed stools.

Question 2

A patient comments, I don't understand why I have chest pain at times when I'm resting or exercising. How will metoprolol (Toprol XL) help? Which of the following comments made by the nurse is correct?
 
  a. It improves sympathetic stimulation to the heart.
  b. You've probably had several minor heart attacks, therefore SL nitroglycerin would be more appropriate.
  c. It improves the right ventricular ejection fraction.
  d. It increases exercise tolerance

Answer to Question 1

A
The most appropriate response from the nurse should be that methylcellulose is a bulk-forming agent that acts by giving the stool a more firm, less watery consistency by bulking it up.
Methylcellulose does not reduce the volume of diarrhea. Loperamide has that action.
Methylcellulose does not reduce intestinal motility, slowing intestinal transit. Opiates have that action.
Methylcellulose does not stimulate the bowel to eliminate diarrhea, leaving only formed stools.

Answer to Question 2

D
When administered on a fixed schedule, beta blockers can provide sustained protection against effort-induced anginal pain. Exercise tolerance is increased, and the frequency and intensity of anginal attacks are reduced, thus reducing stress on the heart.
Beta blockers reduce oxygen demand and block sympathetic stimulation.
Nothing indicates that this patient has suffered a heart attack, therefore a statement referring to a heart attack would be a poor choice.
Beta blockers may in fact reduce the ejection fraction, as well as AV conduction and contractili-ty.

Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs.
