The practical nurse (PN) positions a temporal artery scanner as seen in the picture. Before obtaining a temperature measurement, which assessment of the skin should the PN complete?

A. Give ibuprofen 400 mg PO every 6 hours PRN for fever
The client has a fever of 101.5° F (38.6° C), so administering ibuprofen to manage the fever is appropriate.
B. Give 1,000 mL sodium chloride now
This prescription is already ordered and being administered, so it does not need to be requested again.
C. Discontinue the peripheral IV
The client needs IV access for fluid administration and potential medications, so discontinuing the peripheral IV is not appropriate.
D. Insert an indwelling urinary catheter
There is no indication of urinary retention or need for precise fluid measurement, making this intervention unnecessary at this time.
E. Apply cardiac telemetry monitoring
Given the client's elevated heart rate and respiratory rate, cardiac telemetry monitoring would help in continuously assessing the client's cardiac status.
F. Collect blood to test electrolyte levels
Due to the client's symptoms and history of decreased fluid intake, electrolyte imbalance is a concern, and testing electrolyte levels is necessary.
G. Prepare to defibrillate the client
There is no indication of a cardiac emergency that would require defibrillation.
H. Collect blood for a type and screen
There is no indication of the need for a blood transfusion, making this intervention unnecessary.

A. Observing for signs of pain or discomfort during the treatment is not a direct method for evaluating ondansetron’s effectiveness. Ondansetron is used to prevent nausea and vomiting, not to manage pain.
B. While assessing vital signs is important for overall monitoring, it does not specifically measure the effectiveness of ondansetron for preventing nausea and vomiting.
C. Monitoring for nausea or vomiting following the treatment is the most direct way to evaluate the effectiveness of ondansetron. The primary goal of ondansetron is to prevent or reduce these symptoms associated with chemotherapy.
D. Evaluating if the client feels calm and relaxed is not a measure of ondansetron’s effectiveness. The focus should be on the medication’s ability to prevent nausea and vomiting rather than the client's emotional state before treatment.
