Nursing Elites

1. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:

• A. Inhales as rapidly as possible when using the meter
• B. Records the highest of three readings
• C. Uses the meter after taking a bronchodilator
• D. Blows out forcefully into the meter after taking a deep breath

Correct answer: B

Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.

2. A client with cirrhosis is at risk for bleeding due to impaired liver function. Which laboratory result is the most important to monitor?

• A. Blood urea nitrogen (BUN)
• B. Prothrombin time (PT)
• C. Aspartate aminotransferase (AST)
• D. Serum albumin

Correct answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

3. A client with chronic renal failure has a potassium level of 6.5 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement.
• B. Notify the healthcare provider immediately.
• C. Administer calcium gluconate.
• D. Restrict the client's potassium intake.

Correct answer: B

Rationale: A potassium level of 6.5 mEq/L indicates hyperkalemia, which can lead to life-threatening arrhythmias. The correct priority action for the nurse is to notify the healthcare provider immediately. Hyperkalemia requires prompt intervention to lower potassium levels and prevent complications. Administering a potassium supplement (Choice A) would worsen the condition. Administering calcium gluconate (Choice C) is a treatment option but is not the nurse's priority action. Restricting the client's potassium intake (Choice D) may be necessary but is not the immediate priority when facing a critical potassium level.

4. A nurse is caring for a client with a chest tube following lung surgery. What is the most important intervention to ensure the chest tube functions properly?

• A. Clamp the tube if there is excessive drainage
• B. Empty the drainage chamber every 2 hours
• C. Keep the drainage system below chest level
• D. Milk the tube to prevent clots from forming

Correct answer: C

Rationale: The correct answer is C. Keeping the chest tube drainage system below chest level ensures that gravity assists with drainage and prevents fluid or air from flowing back into the pleural space, which could compromise lung function. Clamping the tube if there is excessive drainage (choice A) is incorrect as it can lead to a buildup of pressure and compromise the drainage system. Emptying the drainage chamber every 2 hours (choice B) is important but not as crucial as maintaining the drainage system below chest level. Milking the tube to prevent clots from forming (choice D) is incorrect and could lead to complications such as tube occlusion or damage to the tissue.

5. Which of these clients, all in the terminal stage of cancer, is least appropriate to suggest the use of patient-controlled analgesia (PCA) with a pump?

• A. A young adult with a history of Down syndrome
• B. A teenager who reads at a 4th-grade level
• C. An elderly client with numerous arthritic nodules on the hands
• D. A preschooler with intermittent alertness episodes

Correct answer: D

Rationale: The correct answer is D. A preschooler with intermittent alertness episodes is not a suitable candidate for patient-controlled analgesia (PCA) due to their inability to effectively manage the system. In the context of terminal cancer, it is crucial for the patient to be able to utilize the PCA system appropriately to manage pain effectively. Preschoolers may not have the cognitive ability or understanding to operate a PCA pump compared to the other clients. Choices A, B, and C present clients with conditions that do not inherently impede their ability to use a PCA pump effectively.
