A client has been taking oral antibiotic therapy for 3 days when she develops diarrhea. The most likely cause of the diarrhea is:
 
  1. disruption of normal flora.
  2. idiopathic causes.
  3. hospital-acquired infection.
  4. fluid volume excess.

Question 2

A nurse is planning to administer acetaminophen (Tylenol) per rectum to a client. The nurse expects:
 
  1. Onset of action to be slower than that of the oral route.
  2. Onset of action to be faster than that of the oral route.
  3. Onset of action to be faster than that of the intravenous route.
  4. The onset of constipation.

Answer to Question 1

Correct Answer: 1
Rationale 1: Disruption of normal flora by the antibiotics is the likely cause.
Rationale 2: There is a likely cause related to antibiotic therapy.
Rationale 3: The cause is likely iatrogenic.
Rationale 4: Fluid volume excess is not the likely cause.
Global Rationale: The colon harbors a substantial amount of bacteria and fungi, called the host flora, which serve a useful purpose by synthesizing B-complex vitamins and vitamin K. Disruption of the normal host flora can lead to diarrhea. While a hospital-acquired infection is possible, it is not the most likely reason. There is a reason for the change, so it is not idiopathic. Fluid volume excess is not suggested as cause.

Answer to Question 2

Correct Answer: 1
Rationale 1: The onset of action for drugs given per rectum is usually slower than that of the oral route.
Rationale 2: The onset of action for drugs given per rectum is not faster than that of the oral route.
Rationale 3: The intravenous route of drug administration has been shown to have the fastest onset of action of all the routes of drug administration.
Rationale 4: Constipation is not usually an adverse effect of rectal acetaminophen administration.
Global Rationale: The onset of action is usually slower than the oral route, and drug action is limited by the length of time that the patient can retain the drug without defecation. Onset of action is slower than intravenous route. Constipation is not an adverse effect of rectal acetaminophen administration.
