A nurse is preparing to administer haloperidol 75 mg IM per week. Available is haloperidol decanoate 100mg/ml for injection. How many ml should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies.
The Correct Answer is ["0.75"]
To calculate the volume (ml) of haloperidol decanoate needed for a dose of 75 mg, you can use the following formula:
Volume (ml) = Dose (mg) / Concentration (mg/ml)
Given:
Dose = 75 mg
Concentration = 100 mg/ml
Plugging in the values:
Volume (ml) = 75 mg / 100 mg/ml
Volume (ml) = 0.75 ml
Rounding to the nearest hundredth:
Volume (ml) = 0.75 ml
So, the nurse should administer 0.75 ml of haloperidol decanoate for the dose of 75 mg.

Correct Answer is D
Explanation
A. Discuss self-defense techniques with the client: Incorrect
While self-defense techniques can be useful information, discussing them immediately after a traumatic event like sexual assault may not be appropriate. The client's immediate needs for emotional support, medical evaluation, and safety are more pressing.
B. Give the client a bed bath prior to physical examination: Incorrect
In cases of sexual assault, preserving evidence is important for legal purposes and for the client's well-being. Providing a bed bath could potentially compromise evidence and hinder a thorough examination by healthcare professionals.
C. Inform the client photographs of injuries are required for a police report: Correct
Preserving evidence is crucial in cases of sexual assault, especially if the client intends to involve law enforcement. Informing the client about the importance of photographs for a police report is appropriate and can contribute to a potential legal investigation.
D. Ask the client to describe the situation: Correct
It's important to encourage the client to share their experience, but it should be done in a sensitive and supportive manner. Gathering information about the situation can help the healthcare team understand the scope of the assault, provide appropriate medical care, and offer necessary emotional support.
Correct Answer is C
Explanation
A. A pretreatment electroencephalogram (EEG) will be done.
An EEG is not typically necessary when starting valproate for bipolar disorder. EEGs are more commonly used to assess brain activity in the context of epilepsy.
B. High serum sodium levels can cause toxic levels of valproate.
Sodium levels are not directly related to the toxic levels of valproate. The primary concern with valproate is its impact on liver function and potential for hepatotoxicity.
C. Liver function tests must be monitored.
Explanation: Valproate is an antiepileptic and mood-stabilizing medication commonly used to treat bipolar disorder. One of the potential side effects of valproate is hepatotoxicity (liver damage). Therefore, monitoring liver function tests (such as serum transaminases) is important to assess the medication's impact on the liver and to ensure the client's safety.
D. Thyroid function tests should be performed every 6 months.
While thyroid function tests might be important for some medications, monitoring thyroid function is not a primary consideration when using valproate. The main focus with valproate is on liver function monitoring.
