Nursing Elites

1. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

2. A client has suspected compartment syndrome of the right lower leg. What is the nurse’s priority intervention?

• A. Elevate the right leg to reduce swelling.
• B. Loosen any restrictive dressings on the leg.
• C. Prepare the client for emergency surgery.
• D. Administer pain medication as prescribed.

Correct answer: B

Rationale: In a suspected case of compartment syndrome, the nurse's priority intervention is to loosen any restrictive dressings on the leg. This action helps to relieve pressure within the affected compartment, improve circulation, and prevent permanent damage. Elevating the leg may further increase pressure, preparing for emergency surgery is premature without proper assessment and diagnosis, and administering pain medication should come after addressing the primary issue of relieving pressure.

3. Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

• A. White blood cell count.
• B. Prothrombin time (PT) and International Normalized Ratio (INR).
• C. Hemoglobin and hematocrit.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

4. A client is admitted with a large bowel obstruction. What finding should the nurse report immediately?

• A. Absence of bowel sounds in all four quadrants.
• B. Abdominal distention with a firm, rigid abdomen.
• C. Frequent, small, liquid stools.
• D. Nausea and vomiting that worsens after meals.

Correct answer: B

Rationale: Abdominal distention with a firm, rigid abdomen is a concerning sign that may indicate perforation, which requires immediate intervention. The rigidity suggests a complication of the large bowel obstruction. Absence of bowel sounds in all four quadrants, option A, is a common finding in a bowel obstruction but not as alarming as a rigid abdomen. Frequent, small, liquid stools, option C, are not typical findings in a large bowel obstruction; instead, constipation is more common. Nausea and vomiting that worsens after meals, option D, are also common symptoms of a bowel obstruction but do not indicate an immediate life-threatening complication like a perforation.

5. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.
