A client with neuroleptic malignant syndrome receives a prescription for dantrolene 1.5 mg/kg IV. The client weighs 132 pounds.
The label on the 250 mg vial reads, “Reconstitute with 5 mL sterile water for injection, USP. Reconstitution yields 50 mg/mL.”. How many mL should the nurse administer?
The Correct Answer is ["1.8"]
The client weighs 132 pounds. To convert pounds to kilograms, divide the weight in pounds by
2.2. So, the client’s weight in kilograms is: Step 1: 132 pounds ÷ 2.2 = 60 kg The prescription for dantrolene is 1.5 mg/kg. To find out how many milligrams the client should receive, multiply the client’s weight in kilograms by the dosage in mg/kg: Step 2: 60 kg × 1.5 mg/kg = 90 mg The vial is reconstituted to yield a concentration of 50 mg/mL. To find out how many mL the nurse should administer, divide the total dosage in milligrams by the concentration in mg/mL: Step 3: 90 mg ÷ 50 mg/mL = 1.8 mL So, the nurse should administer 1.8 mL of dantrolene.

Correct Answer is A,D,B,C
Explanation
- Complete a focused assessment: The first step in managing a patient with abdominal pain and other symptoms is to perform a comprehensive assessment. This will help identify the cause of the symptoms and guide subsequent interventions.
- Offer PRN pain medication: Once the immediate risks have been addressed, managing the patient’s pain is a priority. However, the choice of pain medication will depend on the results of the assessment.
- Send the emesis sample to the lab: Sending the emesis sample to the lab can provide valuable information about the cause of the patient’s symptoms. However, this is not as urgent as the other interventions.
- Elevate the head of the bed: Elevating the head of the bed can help reduce the risk of aspiration, especially in a patient who has vomited. This should be done as soon as possible.
Correct Answer is C
Explanation
Choice A rationale
Paying close attention to the client’s account of the event is important, but it is not the most crucial intervention. The nurse should listen empathetically and nonjudgmentally to the client’s account, but this should not take precedence over ensuring the client’s physical well- being and preserving evidence.
Choice B rationale
Reporting the incident to the university’s security department is not the most crucial intervention. While it is important to report the incident to the appropriate authorities, the nurse’s primary responsibility is to the client. Ensuring the client’s physical well-being and preserving evidence should take precedence.
Choice C rationale
Preventing the client from showering until all evidence is collected is the most crucial intervention. Showering can destroy valuable physical evidence that can be used in the investigation and prosecution of the crime.
Choice D rationale
Ascertaining the client’s personal reaction to the reported rape is important, but it is not the most crucial intervention. The nurse should provide emotional support and refer the client to counseling services, but this should not take precedence over ensuring the client’s physical well-being and preserving evidence.
