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. Diazepam (Valium) is a benzodiazepine used for anxiety. While benzodiazepines can cause sedation and might carry a risk of dependence, they are not typically associated with an increased risk of suicidal ideation compared to antidepressants.
B. Diphenhydramine (Benadryl) is an antihistamine that might cause drowsiness and sedation. It's not primarily used for anxiety disorders, and it's less associated with increased suicidal risk compared to antidepressants.
C. Propranolol (Inderal) is a beta-blocker used for treating conditions like hypertension and anxiety disorders. It's not typically associated with an increased risk of suicide compared to antidepressants.
D. A client who has obsessive-compulsive disorder and takes fluoxetine (Prozac).
Fluoxetine (Prozac) is an antidepressant that belongs to the class of medications called selective serotonin reuptake inhibitors (SSRIs). While it's effective for treating OCD, when initiating or adjusting the dosage of an antidepressant like fluoxetine, there can be an increased risk of suicidal ideation or behavior, especially in younger individuals. This risk is particularly prevalent in the initial weeks of treatment or when there are dosage changes.
Correct Answer is B
Explanation
Explanation:
A. While exercise can be beneficial for promoting sleep, suggesting it right before bedtime may not be the most practical advice, as vigorous exercise close to bedtime can sometimes have the opposite effect.
B. "Using alcohol for sleep can become problematic. Would you like to discuss other methods that might help you sleep?"
This response acknowledges the potential issue with using alcohol as a sleep aid and opens the door for further discussion about alternative methods to promote better sleep. Alcohol can disrupt sleep patterns and lead to dependency, so it's important for the nurse to address this concern and explore healthier sleep-promoting strategies.
C. Encouraging the use of alcohol as a way to "take the edge off" is not the best approach, as it may reinforce the client's reliance on alcohol for sleep, which can lead to dependency and other health issues.
D. Suggesting that the client speak with their provider about prescribing a sedative should not be the initial response. It's essential to explore non-pharmacological interventions and lifestyle changes before considering medications, especially sedatives, due to the potential for dependence and side effects.
