A nurse is preparing to administer amoxicillin 30 mg/kg/day in 2 equally divided doses every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension.

How many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["5.6"]

Step 1: Convert the toddler’s weight from pounds to kilograms. 1 kg is approximately 2.2 lb. So, 33 lb ÷ 2.2 = 15 kg.

Step 2: Calculate the total daily dose of amoxicillin. The prescribed dose is 30 mg/kg/day. So, 30 mg/kg/day × 15 kg = 450 mg/day.

Step 3: Since the dose is divided into 2 equal doses every 12 hours, each dose will be half of the total daily dose. So, 450 mg/day ÷ 2 = 225 mg/dose.

Step 4: Calculate the volume of the suspension to administer per dose. The available suspension is 200 mg/5 mL. So, (225 mg/dose ÷ 200 mg) × 5 mL = 5.625 mL/dose. Therefore, the nurse should administer approximately 5.6 mL of the amoxicillin suspension per dose.

Correct Answer is B

Explanation

The pH of gastric secretions is typically low, reflecting the acidic environment of the stomach. A pH reading of 4.0 would be expected if the nasogastric (NG) tube is correctly placed in the stomach.

A. Don sterile gloves before inserting the indwelling urinary catheter. B. Apply an oil-based lubricant to the indwelling urinary catheter. C. Use one cotton swab to clean the client’s genitalia. D. Test the balloon on the indwelling urinary catheter before insertion.

Correct Answer is A

Explanation

Choice A rationale

Donning sterile gloves before inserting the indwelling urinary catheter is a critical step to prevent infection. The urinary tract is normally sterile, and using sterile gloves helps maintain this sterility during the procedure.

Choice B rationale

Applying an oil-based lubricant to the indwelling urinary catheter is not recommended. Oil- based lubricants can damage latex catheters and increase the risk of infection. A water-soluble lubricant is typically used.

Choice C rationale

Using one cotton swab to clean the client’s genitalia is not sufficient. Proper cleaning and disinfection of the area are crucial to prevent introducing bacteria into the urinary tract during catheter insertion.

Choice D rationale

Testing the balloon on the indwelling urinary catheter before insertion is not typically done. The balloon is usually inflated with sterile water once the catheter is in place to ensure that it remains in the bladder.
