A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr. to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mile How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
Given:
Diphenhydramine syrup: 12.5 mg/5 MLX
Required dose: 25 mg
First, determine the ratio of the available dosage strength to the required dose:
12.5 mg (available dose) / 5 mL (volume) = 25 mg (required dose) / X mL
Cross-multiply to find X (the amount of syrup needed):
12.5 mg X mL = 25 mg 5 mL
Now, solve for X:
X = (25 mg 5 mL) / 12.5 mg
X = 125 / 12.5
X = 10
Therefore, the nurse should administer 10 mL of diphenhydramine syrup to provide a dose of 25 mg to the older adult client with rhinitis.

Correct Answer is D
Explanation
Choice A Reason:
"I will apply heat to my affected ankle to decrease swelling." Heat application is generally not recommended for acute injuries like ankle sprains. Heat can increase blood flow and potentially worsen swelling. Cold therapy (like ice) is typically advised in the early stages to reduce inflammation and swelling.
Choice B Reason:
"I can bear full weight on my affected ankle." For a grade 2 ankle sprain, bearing full weight on the affected ankle might not be advisable initially. Grade 2 sprains involve partial tearing of ligaments and usually require some period of rest or limited weight-bearing to allow healing.
Choice C Reason:
"I can dangle my affected ankle from the edge of the bed. “Dangling the affected ankle from the edge of the bed is a common recommendation to help with gentle movement and improve blood flow without putting excessive stress on the injured ankle. This activity can aid in the recovery process and is often recommended.
Choice D Reason:
"I will wrap my affected ankle with an elastic bandage. “Wrapping the affected ankle with an elastic bandage is a supportive measure recommended for managing ankle sprains. It helps provide compression, support, and stabilization to the injured area, assisting in reducing swelling and providing comfort.
Correct Answer is A
Explanation
A. Elevate the head of the client's bed for 1 hr after the feeding:Elevating the head of the bed helps prevent aspiration and promotes proper digestion by using gravity to keep the feeding solution in the stomach or jejunum.
B. Administer the feeding solution at a cold temperature: Feeding solutions should be administered at room temperature to prevent gastrointestinal discomfort or cramping.
C. Rotate the jejunostomy tube once per day:
Rotation of the jejunostomy tube is not a standard practice. Jejunostomy tubes are typically secured in place, and rotation is not necessary.
D. Flush the tube with 90mL of sterile water before and after the feeding:
Typically, the tube is flushed with about 30 mL of water before and after feedings to ensure patency and prevent clogging, not 90 mL.
