A patient weighing 132 lb is prescribed lorazepam 44 mcg/kg IV to be administered 20 minutes before a scheduled procedure.

The medication is available in a 2 mg/mL vial.

How many mL should the nurse administer? Round off to 2 d.p.

(This is a medical math nd does not require options.)

Answer and Explanation

The Correct Answer is ["1.32"]

Step 1 is to convert the patient’s weight from pounds to kilograms. There are approximately 2.2046 pounds in 1 kilogram. So, the patient’s weight in kilograms is 132 lb ÷ 2.2046 = 59.87 kg.

Step 2 is to calculate the total dose of lorazepam the patient should receive. The prescribed dose is 44 mcg/kg. So, the total dose in micrograms is 44 mcg/kg × 59.87 kg = 2634.28 mcg.

Step 3 is to convert the total dose from micrograms to milligrams. There are 1000 micrograms in 1 milligram. So, the total dose in milligrams is 2634.28 mcg ÷ 1000 = 2.63428 mg.

Step 4 is to calculate the volume of lorazepam solution to administer. The concentration of the solution is 2 mg/mL. So, the volume in milliliters is 2.63428 mg ÷ 2 mg/mL = 1.31714 mL. Therefore, the nurse should administer approximately 1.32 mL of the lorazepam solution, rounding to the nearest hundredth as required.

Correct Answer is []

Explanation

Based on the information provided, the client is most likely experiencinganorexia nervosa.This is suggested by her significant weight loss, bradycardia, hypothermia, lanugo-type hair, and her expressed fear of gaining weight despite being underweight. However, this is a preliminary assessment and a definitive diagnosis should be made by a healthcare professional.

Actions the nurse should take to address this condition include:

Acknowledge anxious feelings: It’s important to validate the client’s feelings and fears about food and weight gain.This can help build trust and facilitate further discussion about her health.
Provide emotional support: Emotional support is crucial in managing eating disorders.The nurse can provide reassurance, listen empathetically, and encourage the client to express her feelings.

Parameters the nurse should monitor to assess the client’s progress include:

Nutritional intake: Monitoring the client’s food and fluid intake can help assess her nutritional status and response to treatment.
Weight and BMI: Regular monitoring of the client’s weight and BMI can provide objective measures of her nutritional status and response to treatment.

A. Allow the child to wear only 100% cotton clothing. B. Apply baby lotion to the skin twice daily. C. Bathe the child daily with bath oil. D. Keep the nails trimmed short.

Correct Answer is D

Explanation

The correct answer is Choice D.

Choice D rationale: Keeping the nails trimmed short is crucial for a child with eczema because it minimizes the damage done when the child scratches their skin. Short nails reduce the risk of breaking the skin and causing infections or further irritation, which can exacerbate eczema symptoms. This preventive measure helps maintain the skin's integrity and reduces the risk of secondary infections.

Choice A rationale: Allowing the child to wear only 100% cotton clothing can help reduce skin irritation as cotton is a soft, breathable fabric. However, it is not as directly related to preventing the harm caused by scratching.

Choice B rationale: Applying baby lotion to the skin can help keep the skin moisturized, but it might not be sufficient for eczema management. A more intensive emollient or specific eczema treatment may be needed.

Choice C rationale: Bathing the child daily with bath oil can help moisturize the skin, but over-bathing can sometimes exacerbate eczema. It's important to use gentle, non-irritating bath products and to follow other guidelines, such as trimming nails.
