When a patient is being administered a 20% mannitol intravenous (IV) solution at a rate of 100 g/24 hours (or 70
mg/min), which outcome data should the practical nurse (PN) prioritize in collection?
Heart rate
Ankle circumference
Urinary output
Dietary intake
The Correct Answer is C
Choice A rationale
Heart rate is an important vital sign to monitor in patients, but it is not the primary outcome
data to prioritize when administering a 20% mannitol intravenous (IV) solution. Mannitol is a diuretic that works by increasing the amount of urine produced. Therefore, while heart rate can be affected by fluid balance changes, it is not the most directly relevant outcome to monitor in this context.
Choice B rationale
Ankle circumference could be an indicator of peripheral edema, which might suggest fluid
overload or poor kidney function. However, in the context of mannitol administration, which is a diuretic and would be expected to decrease fluid overload, ankle circumference is not the primary outcome to monitor.
Choice C rationale
Urinary output is the correct answer. Mannitol is an osmotic diuretic that increases urine
production. It is used to reduce intracranial and intraocular pressure by drawing water out of tissues and into the bloodstream, from where it can be excreted by the kidneys. Therefore, urinary output is the most direct measure of its effectiveness and is the key outcome that should be monitored.
Choice D rationale
Dietary intake is always important to monitor in patients, especially those receiving IV
therapy, as it can impact electrolyte balance and overall health status. However, it is not the primary outcome to monitor when administering mannitol.

Correct Answer is A
Explanation
Choice A rationale
Colchicine and allopurinol are commonly used to manage gout. Colchicine can cause gastrointestinal side effects, including diarrhea. Therefore, it’s important for patients to report any such symptoms to their healthcare provider.
Choice B rationale
While a low-grade fever could potentially be a side effect of many medications, it is not specifically associated with colchicine or allopurinol.
Choice C rationale
Anorexia is not a common side effect of either colchicine or allopurinol.
Choice D rationale
Thinning hair is not a common side effect of either colchicine or allopurinol.
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.
