A nurse in a mental health clinic is reviewing laboratory results for a client who has a prescription for risperidone. For which of the following findings should the nurse notify the provider?

A. Denial:
Denial is a defense mechanism in which a person refuses to accept reality or acknowledge the existence of something that is evident to others. For example, a person diagnosed with a serious illness might deny that they are ill or refuse to believe the diagnosis. In this scenario, the client is not denying a reality; he is expressing anger and directing it toward the nurse.

B. Compensation:
Compensation is a defense mechanism where an individual overachieves in one area to compensate for real or imagined deficiencies in another area. For instance, someone who feels intellectually inferior might excel in sports to compensate for their perceived inadequacy. This is not applicable to the client's situation in the scenario provided.

C. Rationalization:
Rationalization involves providing logical or reasonable explanations to justify behaviors or feelings that might otherwise be unacceptable. For instance, a person might rationalize a failure by blaming external factors rather than accepting personal responsibility. In the scenario, the client is not offering rationalizations but is expressing direct anger.

D. Displacement:
Displacement occurs when emotions, especially anger or frustration, are redirected from the original source to a less threatening target. For example, a person who is angry with their boss might come home and take out their frustration on their family members. In the given situation, the client is displacing his anger from his partner onto the nurse, asking her to leave, making displacement the most appropriate choice.

To find out how many mL the nurse should administer for the total daily dose, we need to calculate the total daily dose and then convert it to mL using the available concentration.

The client is prescribed hydroxyzine 60 mg PO every 8 hours. To find the total daily dose, we can first calculate the dose per day and then convert it to mL.

Dose per day = Dose per dose interval x Number of doses per day

Dose per day = 60 mg x 3 (every 8 hours)

Dose per day = 180 mg per day

Now, we need to convert this dose to mL using the available concentration:

Concentration: 10 mg/5 mL

To find out how many mL for 180 mg, we can set up a proportion:

(10 mg / 5 mL) = (180 mg / x mL)

Cross-multiply:

10 mg * x mL = 5 mL * 180 mg

Now, solve for x (the number of mL):

x mL = (5 mL * 180 mg) / 10 mg

x mL = 900 mL / 10 mg

x mL = 90 mL

So, the nurse should administer 90 mL for the total daily dose.
