Correct Answer: B

Rationale: Setting up the sterile field at waist level is crucial to maintaining its sterility during a dressing change. Choice A is incorrect because sterile gloves should be worn after opening sterile dressing supplies to prevent contamination. Choice C is incorrect as the entire border of the sterile field should be considered contaminated to maintain sterility. Choice D is incorrect because the cap of a sterile solution should never be placed inside the sterile field to prevent contamination.

Correct Answer: A

Rationale: Logrolling is a technique used to move a patient as a single unit to prevent twisting or bending of the spine. Patients who have undergone neck surgery require special care to ensure the spinal column remains in straight alignment to prevent further injury. Therefore, the correct answer is a patient with neck surgery. Choice B, a patient with hypostatic pneumonia, does not require logrolling, as it is a condition affecting the lungs, not the spine. Choice C, a patient with a total knee replacement, does not typically necessitate logrolling, as the procedure focuses on the knee joint, not the spine. Choice D, a patient with a stage IV pressure ulcer, requires wound care but does not necessarily involve logrolling unless the ulcer is located in a critical area that requires special handling.

Correct Answer: B

Rationale: In the scenario described, the client is experiencing symptoms of an anaphylactic reaction, a severe allergic response. The priority action in an anaphylactic reaction is to administer epinephrine. Epinephrine helps counteract the severe allergic response, improves breathing difficulties, and maintains airway and circulation. Administering epinephrine takes precedence to stabilize the client's condition. Options A, C, and D may be necessary in the management of anaphylaxis, but the immediate priority is to administer epinephrine to address the life-threatening symptoms.

Correct Answer: C

Rationale: Morphine IV is the most appropriate choice for severe postoperative pain due to its rapid onset and effectiveness. Meperidine is not preferred due to its potential side effects, and fentanyl patches are typically used for chronic pain, not acute postoperative pain. Oxycodone taken orally is not ideal for providing immediate relief in this situation.
