Correct Answer: A

Rationale: The correct answer is A: 2 L/min. In emphysema, there is impaired gas exchange due to damaged lung tissue, resulting in decreased oxygen levels. Administering too high a flow rate can lead to oxygen toxicity. The standard oxygen therapy for emphysema is 1-2 L/min to maintain oxygen saturation without causing harm. Higher flow rates like 10 L/min (B) and 6 L/min (C) are excessive and can lead to oxygen toxicity. 95 L/min (D) is dangerously high and not suitable for oxygen therapy in emphysema. Therefore, A is the correct choice for safe and effective oxygen administration in emphysema.

Correct Answer: D

Rationale: The correct answer is D: Wheezing. Anaphylaxis is a severe allergic reaction that can lead to airway constriction and difficulty breathing, resulting in wheezing. Wheezing is a common symptom of anaphylaxis due to bronchospasm and airway swelling. Dermatitis (A) is a skin reaction, sinusitis (B) is inflammation of the sinuses, and delirium (C) is a state of mental confusion, which are not typical symptoms of anaphylaxis. Wheezing is a critical symptom in anaphylaxis as it indicates potential airway compromise and the need for immediate medical intervention.

Correct Answer: B

Rationale: The correct answer is B because the inability to move the affected leg post lumbar microdiskectomy could indicate a serious complication like nerve damage or blood clot. This would require immediate medical attention to prevent further complications. Incisional pain (A) is common and can be managed with pain medication. A two-inch area of bleeding on the dressing (C) is concerning but can be managed with proper wound care unless it is excessive. Muscle spasm (D) is also common postoperatively and can be managed with medications or physical therapy.

Correct Answer: A

Rationale: The correct answer is A. The most appropriate outcome for the nurse to include in the plan of care is for the patient to have one soft, formed bowel movement by the end of the shift. This outcome directly addresses the nursing diagnosis of Constipation related to slowed gastrointestinal motility secondary to pain medications. By aiming for a soft, formed bowel movement, the nurse is working towards alleviating the constipation issue caused by the pain medications. This outcome is specific, measurable, achievable, relevant, and time-bound (SMART), making it an appropriate goal for the patient's care plan. Choice B is incorrect because walking unassisted to the bathroom does not directly address the constipation issue. Choice C is incorrect as offering laxatives or stool softeners is a nursing intervention and not an outcome. Choice D is incorrect as withholding pain medications may not be in the best interest of the patient's overall care and does not directly target the constipation issue.

Correct Answer: B

Rationale: Rationale: 1. Oral antidiabetic agents target insulin resistance, common in type 2 diabetes. 2. Type 1 diabetes lacks insulin production, making oral agents ineffective. 3. Choice A is incorrect as insulin cannot be taken orally. 4. Choice C is incorrect as oral agents are not indicated for type 2 diabetes. 5. Choice D is incorrect as pregnancy does not affect the type of diabetes.
