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 B
Explanation
Choice A rationale
Mouth dryness is not a typical therapeutic result of minoxidil. It’s not listed as a common side effect either.
Choice B rationale
Dizziness is a known side effect of minoxidil. It can occur when the medication causes a drop in blood pressure, leading to lightheadedness or dizziness.
Choice C rationale
An elevated blood glucose level is not related to the administration of minoxidil. It could be an unrelated finding, possibly indicating another condition like diabetes.
Choice D rationale
Pain rated at 1/10 is not directly related to the therapeutic effect or side effects of minoxidil. It could be an unrelated finding.
Correct Answer is B
Explanation
Choice A rationale
While it is generally recommended to take prednisone with meals to reduce stomach upset, this is not the most important instruction regarding the dosing schedule.
Choice B rationale
Prednisone is a corticosteroid that is often prescribed in a tapering schedule, meaning the dosage is gradually reduced over time. This is to allow the body to adjust and to minimize potential side effects, such as adrenal insufficiency, which can occur if prednisone is stopped suddenly.
Choice C rationale
While monitoring of blood glucose levels is important for patients taking prednisone, especially those with diabetes, as prednisone can increase blood sugar levels, it is not the most important instruction regarding the dosing schedule.
Choice D rationale
Monitoring of oral temperature daily is not typically required for patients taking prednisone.
