Hesi capstone pn ( 40 Questions)

Question 1 :

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?

Correct Answer: 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.
