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. "Purchase a gift to give to your son from your baby." This is an effective strategy to help a young child feel included and valued, easing the transition and reducing potential jealousy. It fosters a positive emotional connection between the older sibling and the newborn.
B. "Make sure you are holding your baby when your son comes to visit you in the hospital." This may unintentionally make the child feel replaced or left out. It’s better for the parent to be free to hug and reassure the older child during the initial visit.
C. "Use medical terminology when teaching your son about your new baby." Medical terms may confuse or overwhelm a 4-year-old. Simple, age-appropriate language is more effective in helping the child understand the upcoming changes.
D. "Surprise your son with a new bedroom after you bring the baby home." Sudden changes can be disorienting or upsetting for young children. Involving them in the transition process before the baby arrives helps foster a sense of control and comfort.
Correct Answer is C
Explanation
A. A client who has a forehead wound that is bleeding copiously. Although bleeding may appear dramatic, most scalp wounds bleed heavily and can be controlled with pressure. This is not immediately life-threatening if the client is stable.
B. A client who has a compound fracture of the femur and is crying in pain. This is a serious injury with risk for blood loss and infection, but the client is alert and stable enough to express pain, suggesting less immediate neurologic risk than other clients.
C. A client who was unconscious at the scene and now reports diplopia and nausea. This client likely has a head injury with signs of increased intracranial pressure or concussion (diplopia = double vision, nausea, and prior loss of consciousness). These are neurological red flags and require immediate evaluation to prevent deterioration.
D. A client who has several missing teeth and a swollen, ecchymotic upper lip. While painful and concerning, oral trauma without airway compromise is less urgent than potential brain injury.
