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","E"]
Explanation
Choice A rationale
Teaching the client how to use guided imagery can be a helpful intervention for coping with feelings related to death and dying. Guided imagery can help the client to relax, reduce stress and anxiety, and find comfort.
Choice B rationale
Instructing the client and family to reconsider end of life choices is not typically an appropriate intervention. The nurse should respect the client’s end of life choices and provide support, rather than suggesting they reconsider.
Choice C rationale
Recording the client’s desire to live is not typically an intervention used in hospice care. The focus in hospice care is on providing comfort and quality of life, rather than on prolonging life.
Choice D rationale
Encouraging the family to bring the client old photographs can be a helpful intervention. Looking at old photographs can stimulate memories and conversations, providing comfort and connection.
Choice E rationale

Correct Answer is C
Explanation
Choice A rationale
While avoiding exposure to large crowds can help prevent infections, especially for patients with compromised immune systems, it is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.
Choice B rationale
While emotional support is important for patients dealing with health issues, calling a crisis hotline if feeling lonely is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.

This is the most crucial information for the patient. Acetaminophen is found in many over-the- counter medications, and further intake could exacerbate liver damage.
Choice D rationale
While a balanced diet is important for overall health, following a high carbohydrate, low fat, low protein diet is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.
