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 A
Explanation
Choice A Reason:
Elevate the head of the client's bed for 1 hr. after the feeding is appropriate. This action helps minimize the risk of aspiration. Elevating the head of the bed (typically at least 30 to 45 degrees) can reduce the chance of reflux and aspiration of the feeding solution into the lungs. This position should ideally be maintained for about 1 hour after the feeding to aid digestion and reduce the risk of complications.
Choice B Reason:
Administering the feeding solution at a cold temperature is inappropriate. Feeding solutions are generally administered at room temperature or slightly warmed to prevent discomfort and minimize the risk of altering the client's core body temperature. Cold temperatures can cause discomfort or cramping and might affect the absorption of the nutrients. Therefore, administering the feeding solution at a cold temperature is not recommended.
Choice C Reason:
Rotating the jejunostomy tube once per day is inappropriate. Rotating the jejunostomy tube is not typically part of routine care. Tube rotation can cause discomfort, irritation, and potential injury to the gastrointestinal tract. Tubes should be secured properly to prevent movement but not rotated unless specifically instructed by a healthcare provider for a particular reason, such as checking for proper tube placement.
Choice D Reason:
Flushing the tube with 90 ml of sterile water before and after the feeding is inappropriate.
Flushing the tube with sterile water before and after the feeding helps ensure the patency of the tube and prevents clogging. It's a standard procedure to clear the tube and maintain its function
Correct Answer is A
Explanation
Choice A Reason:
Older adults are at increased risk for falls due to decreased vision, balance issues, and decreased reaction time. Placing white or brightly colored tape on the edges of stairs enhances visibility, reducing the risk of missteps and falls.
Choice B Reason:
Placing area rugs on wooden floors is not appropriate. Area rugs on wooden floors can pose a tripping hazard, especially for older adults who might have mobility issues. They can easily slip or trip on loose rugs. Securing rugs with non-slip backing or removing them entirely is a better safety measure.
Choice C Reason:
Running wires and cords under carpeting is not appropriate. Running wires and cords under carpeting can create tripping hazards and increase the risk of electrical issues, including potential overheating and fire hazards. It's safer to secure cords along walls or use cord covers to prevent tripping and reduce potential electrical hazards
Choice D Reason:
Heating systems should be inspected annually to prevent carbon monoxide poisoning and fire hazards. An annual inspection is recommended, especially for older adults who may have impaired smell or cognition, making them less likely to detect gas leaks or heating malfunctions.
