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 ["A","B","D"]
Explanation
A. Sodium level: Correct. Sodium imbalances can have serious consequences, including neurological symptoms. Hyponatremia is a common electrolyte imbalance seen in anorexia nervosa.
B. Blood pressure: Correct. Abnormal blood pressure, especially low blood pressure, can indicate cardiovascular compromise, which is a concern in severe cases of anorexia nervosa.
C. Respiratory rate: Not selected. While monitoring respiratory rate is important, the client's pallor and capillary refill suggest potential issues with peripheral perfusion, making capillary refill more urgent.
D. Capillary refill: Correct. Prolonged capillary refill time is a measure of peripheral perfusion and may indicate poor tissue perfusion, requiring immediate attention.
E. Glucose level: Not selected. While monitoring glucose levels is important, hypoglycemia might not be an immediate concern in this scenario. The client's neurological symptoms may be more related to electrolyte imbalances.
F. Phosphate level: Not selected. Monitoring phosphate levels is important, but severe abnormalities may not require immediate follow-up unless other critical issues are addressed first.
G. Magnesium level: Not selected. Magnesium imbalances are significant but may not require immediate follow-up unless severe abnormalities are noted.
Correct Answer is D
Explanation
A. "You may experience muscle cramping from the induced seizure." While muscle stiffness is possible, the term "muscle cramping" might not accurately describe the postictal state after ECT.
B. "The most common adverse effects of ECT are related to anesthesia." While anesthesia is used during ECT, the most common adverse effects are related to the ECT procedure itself, such as confusion, memory loss, and headache.
C. "You should expect to have ECT once per week for 6 weeks." The frequency and duration of ECT treatments vary based on the individual's response and treatment plan. This statement provides a specific schedule that may not apply to all patients.
D. "You might feel a bit confused and disoriented when you first wake up." This statement accurately reflects a common and expected postictal effect of ECT. Patients undergoing ECT commonly experience confusion and disorientation upon awakening. This is a temporary and expected side effect of the treatment. It's important for the patient to be aware of this possibility as part of the informed consent process.
