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. "I should visually monitor the client continuously when in mechanical restraints." Continuous visual monitoring is required to ensure the client’s safety, monitor for distress or injury, and assess the ongoing need for restraints. This is a key safety standard in the use of mechanical restraints.
B. "I should assess the client's skin integrity every 8 hours while in mechanical restraints." Skin integrity must be assessed much more frequently, typically every 15 to 30 minutes, to prevent injury or pressure-related complications while the client is restrained.
C. "I should expect the provider to evaluate the client within 4 hours of restraint application." For adults, a provider must evaluate the client within 1 hour of the initiation of mechanical restraints. A 4-hour delay does not meet safety or legal standards.
D. "I should ask the provider to write a prescription for mechanical restraints as needed." PRN (as-needed) prescriptions for restraints are not permitted. Each use must be justified, time-limited, and based on the client’s immediate behavior or condition.
Correct Answer is B
Explanation
A. "You should not delegate this task because you have the capability to obtain clients' weights." The ability to perform a task does not mean it cannot be delegated. Delegation helps manage workload effectively as long as the task is appropriate for the role.
B. "You can delegate this task if the AP has been trained to use our scales." Weighing clients is a routine, noninvasive task that can be delegated to assistive personnel, provided they are trained and competent in using the equipment properly.
C. "You can delegate this task to an AP for new clients before performing a nursing assessment." Initial assessments require nursing judgment and should not be delegated. Data collection like weight should occur after the nurse completes the first assessment.
D. "You should not delegate this task because it requires nursing judgment." Weighing a client does not require clinical judgment and is considered appropriate for delegation to trained assistive personnel under supervision.
