A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.1"]
To calculate the amount of haloperidol (in mL) that the nurse should administer, use the following formula:
Volume (mL)= Dose (mg)/Concentration (mg/mL)
In this case:
Volume (mL)=5 mg/50 mg/mL
Volume (mL)= 0.1 mL
Therefore, the nurse should administer 0.1 mL of haloperidol.

Correct Answer is D
Explanation
A. "What happened to you in the past to make you so desperate?" may be seen as judgmental and may not be as helpful in the immediate crisis. It assumes a specific cause for the desperation and might not address the current feelings or circumstances that are contributing to the suicidal thoughts.
B. "What will you accomplish by taking your life?"This question may be perceived as confrontational or dismissive of the client's feelings. It might not provide a clear understanding of the immediate risk or plan.
C. "Why do you feel depressed enough to end your life?" is a direct question that may put pressure on the client and might not be as effective in exploring their thoughts and feelings. It assumes a direct link between depression and suicidal thoughts without allowing for a more nuanced exploration.
D. "How will you carry out your plan?"This question is crucial because it helps assess the seriousness of the client's intent and the immediacy of the risk. Understanding the specifics of the plan can help the nurse evaluate the level of danger and take appropriate actions to ensure the client's safety.
Correct Answer is B
Explanation
A. A client taking olanzapine who experiences dizziness upon standing: While dizziness is a potential side effect, it is not as immediately concerning as the symptoms in the client taking clozapine. Orthostatic hypotension is a known side effect of some antipsychotic medications, and the client may need to be assessed for orthostatic changes.
B. A client taking clozapine who has a sore throat and mild fever.
Clozapine is an atypical antipsychotic that can cause agranulocytosis, a potentially life-threatening condition characterized by a severe reduction in white blood cell count. A sore throat and mild fever can be early signs of infection, and it's crucial to evaluate the client promptly for any indications of agranulocytosis. Regular monitoring of complete blood counts is essential for clients taking clozapine.
C. A client taking risperidone who has gained 5 lb in 3 weeks: Weight gain is a side effect of many antipsychotic medications, including risperidone. While it's important to monitor weight changes, gaining 5 lb in 3 weeks is not as urgent as potential signs of agranulocytosis in the client taking clozapine.
D. A client taking chlorpromazine who is napping frequently throughout the day: Frequent napping may be related to sedation, a common side effect of chlorpromazine. While it's important to assess and address sedation, it is not as urgent as potential signs of infection or agranulocytosis in the client taking clozapine
