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.)

Clamp the catheter tubing distal to the sampling port for 15 min. By clamping the tubing distal to the sampling port, it allows urine to accumulate in the tubing, ensuring that the urine specimen obtained is fresh and not from the stagnant urine that has been sitting in the tubing.

Wipe the sample port with an alcohol wipe and let the alcohol dry. Cleaning the sampling port with an alcohol wipe helps reduce the risk of introducing contaminants into the sample during collection, ensuring a more sterile procedure.

Attach a sterile needleless syringe to the sample port and aspirate the specimen. Using a sterile syringe prevents contamination and allows for the collection of a clean urine sample directly from the catheter tubing, maintaining the sterility of the specimen.

Empty the urine into a sterile container labeled with the client identifiers. Transferring the collected urine into a sterile container labeled with the client's identifiers ensures proper identification and handling of the specimen for laboratory analysis.

Document in the client's electronic medical record that the specimen was sent to the laboratory. Documenting in the client's medical record ensures that there is a clear record of the specimen collection, its handling, and its dispatch to the laboratory for analysis, maintaining proper documentation and continuity of care.

Choice A Reason:
“I'm going to take your heart rate”. This statement is incorrect. Monitoring vital signs like heart rate is essential in assessing a client's condition. However, in this scenario, the client's report of hives, itching, and a potential allergic reaction is more indicative of an immediate concern for anaphylaxis. While monitoring heart rate is relevant, assessing for signs of anaphylaxis, especially difficulty breathing, takes precedence due to the urgency of potential respiratory distress.
Choice B Reason:
"I need to give you diphenhydramine". This statement is incorrect, administering an antihistamine like diphenhydramine can help alleviate allergic symptoms, including itching and hives. However, confirming the severity of the reaction and ensuring there are no life-threatening symptoms such as breathing difficulties is the immediate priority before administering any medication.
Choice C Reason:
"Are you having difficulty breathing?" This statement is correct. This question directly assesses the client's respiratory status, a crucial indicator of anaphylaxis. If the client is experiencing difficulty breathing, it indicates a severe allergic reaction that requires immediate intervention and emergency medical attention. Recognizing and addressing potential respiratory distress is of utmost importance in managing an allergic reaction to medication.
Choice D Reason:
"Do you have any allergies to medications? This statement is incorrect. Understanding the client's medical history, including allergies, is crucial. However, in this acute situation where the client is already experiencing symptoms of a potential allergic reaction shortly after receiving penicillin, addressing the current symptoms and assessing for signs of anaphylaxis is the most immediate concern.
