A nurse is caring for a client who has urticaria following administration of an antibiotic. Which of the following medications should the nurse prepare to administer?
Diphenhydramine
Hydralazine
Naloxone
Protamine
The Correct Answer is A
A. Diphenhydramine. Urticaria (hives) is a common allergic reaction often caused by medications like antibiotics. Diphenhydramine, an antihistamine, is used to treat allergic reactions by blocking histamine receptors, reducing itching, swelling, and rash.
B. Hydralazine. This is an antihypertensive medication used to treat high blood pressure, not allergic reactions. It has no effect on histamine or allergic symptoms.
C. Naloxone. Naloxone is an opioid antagonist used to reverse opioid overdose. It does not treat allergic reactions like urticaria unless the cause is opioid-induced (which is not indicated here).
D. Protamine. Protamine is used to reverse the effects of heparin. It has no role in treating allergic reactions to antibiotics.

Correct Answer is A
Explanation
A. Assess the client's peripheral pulses every 15 min. Frequent assessment of peripheral pulses, especially in the affected extremity, is essential to monitor for signs of arterial occlusion, hematoma, or compromised circulation following a femoral catheterization.
B. Change the client's dressing 4 hr following the procedure. The initial pressure dressing should not be disturbed unless there are signs of bleeding or saturation. Routine dressing changes this soon can disrupt the clotting process at the insertion site.
C. Instruct the client to flex the right knee every 30 min. The client should keep the affected leg straight to prevent disrupting the insertion site. Flexing the knee can increase the risk of bleeding and compromise the integrity of the puncture site.
D. Elevate the head of the client's bed to 45°. Elevating the head of the bed too high can increase abdominal pressure on the femoral site, risking bleeding. The bed should be kept no higher than 30° to reduce stress on the insertion area.
Correct Answer is A
Explanation
A. Action. The action stage involves actively modifying behaviors, practices, or environments. Since the group is already in the process of reducing pesticide use, they are implementing change, which is characteristic of this stage.
B. Contemplation. In the contemplation stage, individuals or groups are aware a problem exists and are thinking about making a change but have not yet taken action. This does not apply here, as the group has already begun changing their practices.
C. Maintenance. The maintenance stage occurs after a behavior has been successfully adopted and sustained for a period of time. The goal in this stage is to prevent relapse and continue positive behavior, which the group has not yet reached.
D. Preparation. The preparation stage includes planning and small initial steps toward change but not full implementation. Since the group is already working on reducing pesticide use, they have moved beyond this stage.
