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 C,A,B,D
Explanation
Choice C rationale
The first step in managing a patient with abdominal pain and distention is to complete a focused assessment. This will help the nurse determine the severity of the patient’s condition and guide subsequent interventions.
Choice A rationale
Elevating the head of the bed can help reduce the risk of aspiration, especially in a patient who has recently vomited. This is particularly important in this case as the patient’s vomit is dark brown, indicating possible upper gastrointestinal bleeding.
Choice B rationale
Sending the emesis sample to the lab is important for determining the cause of the patient’s symptoms. The lab can analyze the sample for the presence of blood or other abnormalities.
Choice D rationale
Offering PRN pain medication is important for patient comfort. However, it should be done after the assessment and initial interventions have been completed. The medication may mask symptoms that could provide important diagnostic information.
Correct Answer is C
Explanation
Choice A rationale
Vegetarian lasagna with cheese and spinach, a tossed green salad with ranch dressing, and fresh fruit is a balanced meal. However, it may not be the best choice for a patient with type 2 diabetes due to the high carbohydrate content in the lasagna and the dressing.
Choice B rationale
Fried chicken breast, mashed potatoes, green beans, sliced tomatoes, and fresh apple pie is not the best choice for a patient with type 2 diabetes. Fried foods and mashed potatoes are high in carbohydrates and fats, which can raise blood sugar levels.
Choice C rationale
Grilled fish with whole-grain brown rice, steamed broccoli, and a pear poached in red wine is a good choice for a patient with type 2 diabetes. This meal is balanced with lean protein, whole grains, and vegetables, which can help control blood sugar levels.
Choice D rationale
Lean hamburger with cheese, tomato, and lettuce on a whole-wheat bun, and angel food cake is not the best choice for a patient with type 2 diabetes. Although the hamburger is lean, the whole-wheat bun and angel food cake are high in carbohydrates, which can raise blood sugar levels.
