A patient has been prescribed intravenous (IV) famotidine.
Which observation would indicate to the practical nurse (PN) that the medication is having the desired effect?
Decreased nighttime awakenings.
Positive stool antigen test.
Loss of 3 pounds (1.36 kg) in a month.
Reduced epigastric pain.
The Correct Answer is D
Choice A rationale
Famotidine is a type of medication known as an H2 blocker, which decreases the amount of
acid produced in the stomach. While it can indirectly lead to better sleep by reducing
discomfort, decreased nighttime awakenings is not a direct indicator of its effectiveness.
Choice B rationale
A positive stool antigen test is used to detect the presence of certain bacteria in the
gastrointestinal tract. It is not directly related to the action of famotidine.
Choice C rationale
Weight loss is not a typical result of famotidine use. If a patient experiences significant weight
loss, other causes should be investigated.
Choice D rationale
Famotidine is used to treat conditions like ulcers, gastroesophageal reflux disease (GERD), and
conditions where the stomach produces too much acid, like Zollinger-Ellison syndrome.
Reduced epigastric pain indicates that the medication is effectively reducing stomach acid and
therefore, alleviating symptoms.

Correct Answer is C
Explanation
Choice A rationale
Diminished urinary urgency is an expected outcome of oxybutynin treatment, as the
medication works by relaxing the muscles of the bladder.
Choice B rationale
Reduced urinary frequency is another expected outcome of oxybutynin treatment.
Choice C rationale
Decreased urinary output is not a typical effect of oxybutynin. In fact, oxybutynin is used to
manage symptoms of an overactive bladder, which include frequent urination. Therefore, if the
PN observes decreased urinary output, it could indicate a problem such as urinary retention,
which should be reported to the charge nurse.
Choice D rationale
Less frequent urinary incontinence is an expected outcome of oxybutynin treatment.
