The practical nurse (PN) is caring for a client who has a finger stick blood glucose result of 130 mg/dL (7.21 mmol/L). Prior to administering the scheduled dose of acarbose, the PN is informed that the morning meal trays will be delayed 30 minutes.
Which action should the PN take?
Administer the medication.
Notify the healthcare provider.
Obtain another finger stick blood glucose level.
Hold the medication until the meal tray arrives.
The Correct Answer is D
The correct answer is Choice D, Hold the medication until the meal tray arrives. Acarbose is an oral antidiabetic medication that works by slowing the digestion of carbohydrates in the small intestine, thereby reducing the rise in blood glucose after meals. It is important to take acarbose at the start of each main meal, as it works on the food that is consumed. If the meal is delayed, the medication should also be delayed.

Correct Answer is C
Explanation
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 C
Explanation
Choice C rationale
Keratolytics are medications designed to dissolve skin flakes and scales. In the treatment of psoriasis, a condition characterized by thick, scaly patches of skin, the desired effect of a keratolytic would be to soften and reduce these scales.
Choice A rationale
While no purulent drainage present from lesions on the legs could be a positive sign in the treatment of psoriasis, it is not a direct result of the keratolytic properties of the applied preparation.
Choice B rationale
Affected areas being free of localized redness and swelling could be a positive sign in the treatment of psoriasis, but it is not a direct result of the keratolytic properties of the applied preparation.
Choice D rationale
Full range of motion without pain of lower extremity joints is not a direct result of the keratolytic properties of the applied preparation. It could be a positive sign in the overall treatment of psoriasis, but it is not directly related to the use of a keratolytic.
