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.)
The Correct Answer is ["0.25"]
To calculate the volume of haloperidol solution needed, we can use the formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
Given: Dose of haloperidol = 5 mg
Concentration of haloperidol solution = 20 mg/mL
Substituting the given values into the formula:
Volume (mL)=5 mg/20 mg/mL
Volume (mL)=5/20
Volume (mL)=0.25 mL
Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.

Correct Answer is D
Explanation
Children can often be resistant to taking medication, but offering them choices and involving them in the process can help promote cooperation. Here's the rationale for each option:
A. Tell the child it is candy: This strategy involves deception and can lead to trust issues if the child discovers the truth. It's not ethical or recommended to lie to a child about medication.
B. Tell the child he will have to have a shot instead: Threatening the child with a shot is coercive and can cause fear and anxiety. It's not an appropriate or therapeutic approach to encourage cooperation.
C. Hide the medication in a large dish of ice cream: While hiding medication in food may work for some children, it's important to ensure that the child consumes the entire dose. Additionally, it's essential to check with the healthcare provider or pharmacist to confirm that the medication can be taken with food. However, this approach may not address the underlying issue of the child's resistance to taking medication.
D. Offer the child a choice of taking the medication with juice or water: Offering the child a choice empowers them and gives them some control over the situation. By allowing the child to choose how they take the medication, they may feel more comfortable and cooperative. This approach respects the child's autonomy and can be an effective way to encourage cooperation while ensuring the medication is taken as prescribed.
Correct Answer is B
Explanation
A. Avoid flossing the teeth to prevent gum irritation: There is no evidence to suggest that flossing the teeth increases the risk of gum irritation with phenytoin use. In fact, proper dental hygiene, including flossing, is essential to prevent gum disease, which can be exacerbated by the medication.
B. Alcohol increases the chance of phenytoin toxicity: Consumption of alcohol can increase the risk of phenytoin toxicity by enhancing its effects. Therefore, clients taking phenytoin should avoid alcohol consumption to prevent adverse effects and ensure the medication's efficacy.
C. Take an antacid with the medication if indigestion occurs: Phenytoin can interact with antacids, reducing its absorption and effectiveness. Therefore, clients should not take antacids concurrently with phenytoin unless directed by their healthcare provider.
D. Phenytoin turns urine blue: Phenytoin does not typically cause changes in urine color. This statement is incorrect and not relevant to the client's medication regimen.
