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
a. Have the client wear a surgical mask during transport. This is the appropriate intervention to prevent the spread of the influenza virus when the client needs to be transported within the healthcare facility. Influenza is primarily spread through respiratory droplets, so wearing a surgical mask helps to contain these droplets.
b. Wear an N95 mask while providing care to the client. An N95 mask is generally not required for influenza. Standard precautions, including wearing a surgical mask when within close proximity to the client, are usually sufficient.
c. Administer an influenza immunization to the client. It is not appropriate to administer the influenza vaccine to a client who is already infected with the influenza virus.
d. Place the client in a negative airflow room. Negative airflow rooms are typically reserved for airborne diseases such as tuberculosis. Influenza, which spreads via droplets, does not require this level of isolation.
Correct Answer is C
Explanation
Choice A Reason:
Chill the dialysate prior to infusion. Generally, the dialysate used in peritoneal dialysis is warmed to body temperature before infusion to enhance comfort and prevent abdominal discomfort. Chilling the dialysate can cause discomfort and is not a standard practice in peritoneal dialysis.
Choice B Reason:
Monitor the client for diarrhea. While gastrointestinal symptoms might occur in some individuals undergoing peritoneal dialysis due to changes in fluid balance, diarrhea is not a typical or expected outcome. However, monitoring for any unusual gastrointestinal symptoms or changes in bowel habits is part of holistic client care.
Choice C Reason:
Weigh the client before and after the treatment. Weighing the client before and after peritoneal dialysis is a critical step to assess the effectiveness of the treatment. The difference in weight helps determine how much fluid was removed during the dialysis process, providing valuable information about the treatment's efficacy and the client's fluid status.
Choice D Reason:
Use clean gloves when handling dialysate bags. Maintaining aseptic technique during peritoneal dialysis is crucial to prevent infections. The use of clean gloves (not sterile gloves, unless otherwise specified) when handling dialysate bags helps minimize the risk of contamination, ensuring the safety of the procedure.
