A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.25"]

To calculate the volume of haloperidol solution needed, we can use the formula:

Volume (mL)=Dose (mg)/Concentration (mg/mL)

Given: Dose of haloperidol = 5 mg

Concentration of haloperidol solution = 20 mg/mL

Substituting the given values into the formula:

Volume (mL)=5 mg/20 mg/mL

Volume (mL)=5/20

Volume (mL)=0.25 mL

Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.

Correct Answer is ["A","C","E"]

Explanation

Fluid excess, also known as fluid overload or hypervolemia, occurs when there is an excessive volume of fluid in the body. The nurse should assess for signs and symptoms of fluid excess, which include the following:

A. Bounding pulse: A bounding pulse, or a pulse that feels unusually strong and forceful, can be a sign of fluid excess. Increased blood volume leads to increased cardiac output, which can manifest as a bounding pulse.

B. Urine-specific gravity greater than 1.030: Urine-specific gravity greater than 1.030 typically indicates concentrated urine and is more indicative of dehydration rather than fluid excess.

C. Pitting edema: Pitting edema occurs when pressure is applied to the skin, resulting in an indentation or "pit" that persists after the pressure is released. It is a classic sign of fluid excess, indicating fluid accumulation in the interstitial spaces.

D. Swelling at the IV site: Swelling at the IV site may indicate infiltration or phlebitis rather than fluid excess. While fluid excess can lead to generalized swelling, swelling specifically at the IV site may suggest a local issue related to the IV infusion.

E. Crackles upon auscultation: Crackles, also known as rales, are abnormal lung sounds heard upon auscultation and are indicative of fluid accumulation in the lungs, which can occur with fluid excess. Crackles are typically heard in the bases of the lungs and may indicate pulmonary edema.

A. Akathisia B. Neuroleptic malignant syndrome C. Tardive dyskinesia D. Agranulocytosis

Correct Answer is B

Explanation

A. Akathisia: Akathisia is characterized by restlessness and an inability to sit still. While it can be a side effect of antipsychotic medications like haloperidol, it does not present with fever, hypertension, and muscle rigidity, as described in the scenario.

B. Neuroleptic malignant syndrome (NMS): NMS is a potentially life-threatening condition associated with antipsychotic medications like haloperidol. It is characterized by hyperthermia, autonomic dysfunction (e.g., hypertension), altered mental status, and severe muscle rigidity. The client's symptoms of fever, elevated blood pressure, and muscle rigidity are consistent with NMS.

C. Tardive dyskinesia: Tardive dyskinesia is a movement disorder characterized by involuntary, repetitive movements of the face, tongue, and other body parts. It is a long-term side effect of antipsychotic medications and typically develops after prolonged use, unlike the acute onset seen in the scenario.

D. Agranulocytosis: Agranulocytosis is a rare but serious side effect of antipsychotic medications, characterized by a severe reduction in white blood cell count, leading to an increased risk of infection. The symptoms described in the scenario are not consistent with agranulocytosis.
