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
Explanation
Choice A rationale
After a gastric endoscopy, it’s common for patients to experience a sore throat. This is due to the passage of the endoscope through the throat during the procedure. The discomfort is usually temporary and can be relieved with lozenges or gargling with warm salt water.
Choice B rationale
While headaches can occur after procedures that involve sedation, they are not commonly associated with gastric endoscopy specifically. Therefore, while it’s important to monitor for headaches, they are not a typical post-procedure problem following a gastric endoscopy.
Choice C rationale
Aching legs are not a common problem following a gastric endoscopy. The procedure primarily involves the upper gastrointestinal tract, and does not directly affect the legs.
Choice D rationale
Nausea can occur after a gastric endoscopy, but it is more commonly associated with the sedation used during the procedure rather than the procedure itself. If nausea does occur, it can be managed with antiemetic medications.
Correct Answer is C
Explanation
Choice A rationale
Ignoring the behavior and proceeding with the IV antibiotic administration is not the best course of action. This would be an invasion of the patient’s privacy and could potentially lead to legal issues. It is important to respect the patient’s privacy and dignity at all times.
Choice B rationale
Instructing the patient to cease the inappropriate behavior is not the best course of action. While the behavior is inappropriate, it is not the nurse’s place to reprimand the patient. This could lead to a breakdown in the nurse-patient relationship and could potentially escalate the situation.
Choice C rationale
Exiting the room and closing the door quietly is the best course of action. This respects the patient’s privacy and allows the patient and visitor to finish their activity. The nurse can then return at a later time to administer the IV antibiotic.
Choice D rationale
Filling out an unusual occurrence report is not necessary in this situation. While the behavior is inappropriate, it is not an unusual occurrence that requires reporting. The nurse should handle the situation professionally and with discretion.
