Nursing Elites

1. A client is admitted to the hospital with a diagnosis of pneumonia. The client is prescribed intravenous antibiotics and oxygen therapy. Which assessment finding indicates that the client's condition is improving?

• A. Increased white blood cell count
• B. Crackles heard on lung auscultation
• C. Productive cough with green sputum
• D. Decreased respiratory rate from 24 to 18 breaths per minute

Correct answer: D

Rationale: A decrease in respiratory rate indicates that the client's breathing is becoming more stable, which suggests an improvement in their condition. Respiratory rate is a critical indicator of respiratory status and oxygenation. Increased white blood cell count (choice A) suggests ongoing infection, crackles on lung auscultation (choice B) indicate fluid in the lungs, and productive cough with green sputum (choice C) may indicate persistent infection or airway inflammation, which do not necessarily reflect improvement in pneumonia.

2. 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.

3. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.

4. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

5. The nurse is administering an intradermal injection for a tuberculosis skin test. Which technique should the nurse use?

• A. Use a 25-gauge needle at a 90-degree angle
• B. Use a 27-gauge needle at a 15-degree angle
• C. Use a 22-gauge needle at a 45-degree angle
• D. Use a 20-gauge needle at a 90-degree angle

Correct answer: B

Rationale: An intradermal injection for a tuberculosis skin test should be administered using a 27-gauge needle at a 15-degree angle. This technique ensures that the medication is delivered into the dermis layer of the skin. Choice A is incorrect because a 25-gauge needle is too large for an intradermal injection. Choice C is incorrect as a 22-gauge needle is also too large and the angle is too steep for an intradermal injection. Choice D is incorrect as a 20-gauge needle is too large for an intradermal injection, and a 90-degree angle would not deliver the medication accurately into the dermis.
