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 C
Explanation
A) "My child was born with a birth defect due to an exposure I had overseas."
This statement does not directly relate to the core symptoms of PTSD. While exposure to trauma can have a variety of consequences, including potential exposure-related health issues, this statement does not necessarily indicate the re-experiencing, avoidance, or hyperarousal symptoms characteristic of PTSD.
B) "I check any room I enter because the enemy is still after me and could be hiding anywhere."
This statement is more indicative of hyperarousal and hypervigilance, which are common symptoms of PTSD. However, it does not explicitly involve re-experiencing the traumatic event through nightmares or intrusive memories, as described in the correct answer.
C) "In my dreams, all I can see are the wounded reaching out and trying to grab me."
Explanation:
The statement "In my dreams, all I can see are the wounded reaching out and trying to grab me" indicates symptoms commonly associated with posttraumatic stress disorder (PTSD). This statement reflects the re-experiencing symptom cluster of PTSD, where individuals may have distressing and intrusive memories, nightmares, or flashbacks related to the traumatic event they experienced. The imagery of wounded individuals trying to grab the person suggests a strong emotional impact and ongoing distress related to the traumatic experience.
D) "I killed four enemy soldiers with my bare hands and saved my entire battalion."
While this statement might reflect exposure to a traumatic event and could contribute to symptoms of PTSD, it is presented in a way that seems more like a narrative of heroic actions rather than a symptom of distress or re-experiencing.
Correct Answer is ["2"]
Explanation
The nurse is preparing to administer benztropine 2 mg IM every 12 hours. The concentration of the available benztropine is 1 mg/mL.
To calculate the volume (mL) of the medication needed for the prescribed dose, you can use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = 2 mg / 1 mg/mL = 2 mL
So, the nurse should administer 2 mL of benztropine 1 mg/mL for each dose. Since we're looking for a whole number, we round to the nearest whole number, which is 2 mL.
