A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

A. "It doesn't really matter what time you take your medications as long as you don't skip any doses": This statement is incorrect because adherence to the prescribed dosing schedule is crucial for the effectiveness of medications. Inconsistent timing of doses can lead to suboptimal therapeutic outcomes or potential adverse effects.

B. "Let's work together to devise a time schedule that is convenient for you on a daily basis": This is the most appropriate instruction. Collaborating with the client to establish a medication schedule that aligns with their daily routine increases the likelihood of adherence. It promotes patient autonomy and empowers the client to take ownership of their medication regimen.

C. "You really shouldn't change the schedule we established here in the facility": While maintaining consistency in medication administration times is important, rigidly adhering to a schedule established during the facility stay may not always be feasible or practical for the client at home. Flexibility in adjusting the schedule to fit the client's lifestyle is essential for long-term adherence.

D. "We'll have to talk to your provider about switching to an alternative schedule": Switching to an alternative schedule should be considered only if the current schedule is not feasible for the client or if it compromises medication adherence. However, exploring options for adapting the existing schedule to better suit the client's needs should be attempted first before considering a switch.

A. "I'll be glad when I can stop taking this medicine.": This statement indicates a misunderstanding about phenytoin therapy. Phenytoin is typically a long-term medication used to prevent seizures, and it is not typically discontinued unless under the guidance of a healthcare provider. The nurse should clarify that stopping the medication abruptly can lead to rebound seizures and should emphasize the importance of continuing the medication as prescribed.

B. "I have made an appointment to see my dentist next week.": This statement indicates appropriate understanding, as regular dental check-ups are important for individuals taking phenytoin due to the medication's potential side effect of gingival hyperplasia.

C. "I know that I cannot switch brands of this medication.": This statement demonstrates understanding, as different brands of phenytoin can have variations in bioavailability, which can affect seizure control. It is important for clients to remain consistent with the same brand or formulation unless directed otherwise by their healthcare provider.

D. "I will notify my doctor before taking any other medications.": This statement indicates understanding of the potential for drug interactions with phenytoin, as it is a hepatic enzyme inducer and can affect the metabolism of other medications. Clients should always consult their healthcare provider before taking any new medications or supplements to ensure compatibility with phenytoin therapy.
