Answer and Explanation

The Correct Answer is ["1"]

Convert milligrams (mg) to micrograms (mcg):

The desired dose is 0.5 mg.

We know that 1 mg = 1000 mcg.

Therefore, 0.5 mg = 0.5 x 1000 mcg = 500 mcg.

Identify the available tablet strength:

Each tablet contains 500 mcg of haloperidol.

Set up the calculation:

We need to find out how many tablets are needed to administer 500 mcg of the medication. We can use the following formula:

(Desired dose) / (Tablet strength) = Number of tablets

Plug in the values and calculate:

(500 mcg) / (500 mcg/tablet) = 1 tablet

A. Frequency B. Route C. Medication D. Dose

Correct Answer is A

Explanation

A) Frequency: The prescription indicates "every 4 hours PRN agitation," but there is a potential for ambiguity regarding how often the medication can be safely administered. The nurse should clarify the maximum allowable frequency of haloperidol administration. Typically, PRN medications are prescribed with clear guidelines for frequency to avoid overmedication or harmful side effects, such as sedation or extrapyramidal symptoms. Clarifying the frequency is essential for safe medication administration.

B) Route: The route of administration for haloperidol is typically oral, intramuscular, or intravenous, depending on the specific clinical situation. The prescription does not specify a route, which is why clarification is necessary. However, the route is not as critical to add as the frequency, as the nurse can assume a route based on standard practice or clinical context, provided it is clear to the provider what the patient requires.

C) Medication: Haloperidol is already specified in the prescription. There is no ambiguity regarding which medication is being prescribed. The nurse does not need to ask the provider to add this component of the prescription, as the medication is already identified.

D) Dose: The prescription specifies the dose of haloperidol (2 mg) for every 4 hours PRN agitation. The issue is not with the dose, but rather with the need for clarification on the maximum allowable frequency for its administration. Clarifying the frequency is more critical to ensure safe medication use, especially in managing agitation.
