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.)

Answer and Explanation

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

Explanation

A. Uncontrolled movements around the mouth.
Tardive dyskinesia is a side effect associated with the long-term use of antipsychotic medications, especially first-generation or typical antipsychotics. It is characterized by involuntary, repetitive movements, often involving the face, such as uncontrolled movements around the mouth (e.g., lip smacking, puckering, chewing).

B. Seizures and tremors are not typical adverse effects of tardive dyskinesia. They are more commonly associated with other side effects or conditions.

C. Nausea and vomiting are not typically associated with tardive dyskinesia. These symptoms may be side effects of antipsychotic medications, but they are not characteristic of tardive dyskinesia itself.

D. Hallucinations and delusions are not associated with tardive dyskinesia. Tardive dyskinesia primarily involves involuntary movements and is not related to changes in thought content or perception.

A. Potassium 2.8 mEq/L B. Serum chloride 96 mEq/L C. Hgb 11g/dL D. Serum amylase 240 units/L

Correct Answer is A

Explanation

A. Potassium 2.8 mEq/L
Hypokalemia (low potassium) is a critical finding and a priority in individuals with a history of bulimia nervosa, as it can lead to life-threatening complications such as cardiac arrhythmias and muscle weakness. Frequent vomiting and laxative use, common behaviors in bulimia nervosa, can result in significant potassium loss. A potassium level of 2.8 mEq/L is significantly below the normal range and requires immediate attention.

B. Serum chloride 96 mEq/L: While this value is within the normal range, it should be monitored. However, it is not as critical as addressing severe hypokalemia.

C. Hemoglobin (Hgb) 11 g/dL: This hemoglobin level is within the normal range and does not require immediate attention. It may be influenced by factors other than bulimia nervosa, and addressing hypokalemia is more urgent.

D. Serum amylase 240 units/L: Elevated amylase levels may indicate pancreatic inflammation, which could be related to bulimia nervosa, but it is not as urgent as addressing severe hypokalemia. The priority is managing the life-threatening electrolyte imbalance first.
