A nurse is preparing to administer ziprasidone 10 mg IM every 6 hr. Available is ziprasidone 20 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the amount of ziprasidone 10 mg IM from the available concentration of 20 mg/mL, you can use the formula:
Amount (mL) = Desired Dose (mg) / Concentration (mg/mL)
Amount (mL) = 10 mg / 20 mg/mL
Amount (Ml) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of ziprasidone per dose.

Correct Answer is C
Explanation
A. Regression: Incorrect
Regression is a defense mechanism in which a person reverts to an earlier stage of development in response to stress or anxiety. For example, an adult might start behaving like a child when faced with a difficult situation. In this case, the student berating the teacher doesn't demonstrate a return to an earlier developmental stage, so regression is not the correct choice.
B. Conversion: Incorrect
Conversion refers to the conversion of emotional distress into physical symptoms, such as experiencing physical pain without any apparent physical cause. This mechanism is often seen in conditions like conversion disorder. The student berating the teacher is not exhibiting physical symptoms as a response to emotional distress, so conversion is not the correct choice.
C. Projection: Correct
Projection is the act of attributing one's own unacceptable feelings or thoughts to another person. In this scenario, the student is projecting their own failure onto the teacher and the course by blaming them for the failure. They are unable to accept their own role in the failure and are instead placing the blame on external factors. This aligns with the behavior described in the scenario.
D. Undoing: Incorrect
Undoing involves trying to compensate for or negate an unacceptable action or thought with a contrary action. For instance, someone who had angry thoughts might engage in excessive acts of kindness to "undo" those thoughts. The student berating the teacher is not engaging in actions to negate their negative feelings or thoughts; they are expressing their frustration directly.
Correct Answer is ["24"]
Explanation
To calculate the mL/hr for the heparin infusion, you can use the formula:
mL/hr = (Total units required per hour) / (Units/mL in the solution)
Given:
Total units required per hour = 1,200 U/hr
Units/mL in the solution = 25,000 U / 500 mL = 50 U/mL
Plugging in the values:
mL/hr = (1,200 U/hr) / (50 U/mL)
mL/hr = 24 mL/hr (rounded to the nearest tenth)
Therefore, the nurse should set the IV pump to deliver 24 mL/hr for the heparin infusion.
