A nurse is conducting a nursing health history. Which component will the nurse address?

Correct Answer: B

Rationale: The correct answer is B: Patient expectations. During a nursing health history, the nurse focuses on gathering information about the patient's health concerns, medical history, lifestyle, and expectations for their care. Addressing patient expectations is crucial for providing patient-centered care and establishing a therapeutic relationship. The other choices are incorrect because: A: Nurse's concerns are not the primary focus of a nursing health history. C: Current treatment orders are important but are typically addressed during a physical assessment or when implementing care. D: Nurse's goals for the patient are important but should be developed in collaboration with the patient based on their needs and preferences.

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: B

Rationale: The correct answer is B: "Keep the stoma dry." Keeping the stoma dry helps prevent infection and skin irritation. Moisture can lead to fungal growth and skin breakdown. Option A is incorrect because keeping the stoma uncovered can increase the risk of contamination and infection. Option C is incorrect as self-care promotes independence and allows the client to become familiar with the procedure. Option D is incorrect as moisture can lead to skin issues.

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: D

Rationale: The correct answer is D. Wearing cotton gloves, especially during sleep, helps reduce itching by preventing scratching, which can further irritate the skin. Cotton is a breathable fabric that reduces friction and irritation. A: Humidifying the environment may help in some cases, but it doesn't directly address the itching or maintaining skin integrity. B: Avoiding a skin lubricant is not recommended as it can help moisturize the skin and reduce itching. C: Bathing with a bar soap that contains lye can be harsh and drying, exacerbating the skin reaction.

Correct Answer: B

Rationale: The correct answer is B: Cerebral edema. Hypernatremia is an elevated sodium level in the blood, which can lead to osmotic shifts causing water to move out of cells, including brain cells. This can result in cerebral edema, potentially leading to neurological complications. Incorrect choices: A: Red blood cell crenation - This occurs in hypertonic solutions, not hypernatremia. C: Red blood cell hydrolysis - Hypernatremia doesn't directly cause red blood cell hydrolysis. D: Renal shutdown - Hypernatremia can stress the kidneys, but it doesn't typically lead to renal shutdown.

Correct Answer: A

Rationale: The modified Trendelenburg position involves placing the client with their legs elevated higher than their head. This position promotes venous return to the heart, increasing preload and cardiac output, thereby leading to an increase in blood pressure. Elevating the legs helps to reduce peripheral edema and improve circulation. Therefore, the correct answer is A. Choice B is incorrect because the Trendelenburg position does not directly affect the respiratory rate. Choice C is incorrect as the position is not intended to increase heart rate but rather improve venous return. Choice D is also incorrect as the primary goal of the Trendelenburg position is not to decrease blood loss, although it may help in some cases by improving circulation.

Correct Answer: A

Rationale: Rationale: Intrinsic factor is a glycoprotein produced by the stomach that is essential for the absorption of vitamin B12 in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to megaloblastic anemia. Histamine and hydrochloric acid are not directly involved in vitamin B12 absorption. Liver enzymes are not implicated in the absorption process. Therefore, the correct answer is A.

Correct Answer: A

Rationale: The correct answer is A: Position the client flat for at least 3 hrs or as directed by the physician. Rationale: 1. Positioning the client flat helps prevent post-lumbar puncture headache by allowing the CSF to replenish and stabilize the pressure in the spinal canal. 2. The recommended time frame of 3 hours allows for adequate CSF reabsorption and reduces the likelihood of headache. 3. Following physician's direction is crucial to individualize care based on the specific situation. Summary of other choices: B: Encouraging fluid intake is generally good practice but may not directly alleviate post-lumbar puncture headache. C: Keeping the room well lit and playing soothing music may not address the physiological cause of the client's symptoms. D: Ambulation and leg exercises are not recommended immediately post-lumbar puncture as they may exacerbate dizziness and headache.
