Nclex Exam Cram Practice Questions
1. A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?
- A. Submerge the end of the chest tube in a bottle of sterile water
- B. Clamp the chest tube with a Kelly clamp
- C. Call the health care provider
- D. Instruct the client to inhale and hold his breath
Correct answer: A
Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.
2. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?
- A. urinalysis
- B. creatinine and blood urea nitrogen
- C. chemistry of electrolytes
- D. creatinine clearance
Correct answer: D
Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.
3. The nurse is preparing task assignments for the day. Which task should the nurse assign to a nursing assistant?
- A. Monitoring for bleeding for a client who has just undergone cardiac catheterization
- B. Assisting a client who is getting up to ambulate for the first time after surgery
- C. Providing oral care to an unconscious client who requires oral care
- D. Completing the preoperative checklist for a client scheduled for a liver biopsy
Correct answer: C
Rationale: When delegating tasks, the nurse must consider the state nursing practice act guidelines and job descriptions. Providing oral care to an unconscious client is a task suitable for delegation to a nursing assistant. The nurse should give clear instructions on adapting the procedure for the client's needs and the signs of complications to watch for. Monitoring for bleeding after cardiac catheterization necessitates immediate nursing assessment, which requires critical thinking and intervention that exceeds a nursing assistant's scope of practice. Assisting a client with ambulation post-surgery carries the risk of orthostatic hypotension and should be performed by a licensed nurse. Completing a preoperative checklist for a client scheduled for a liver biopsy involves critical assessment and preparation that are within the nurse's scope of practice.
4. A client with diabetes mellitus who takes a daily dose of NPH insulin has a hard time drawing the insulin into a syringe because he has difficulty seeing the markings on the syringe. To which services does the nurse suggest a referral?
- A. Home care
- B. Occupational therapy
- C. Social services
- D. Physical therapy
Correct answer: B
Rationale: For a client with diabetes mellitus who struggles to draw insulin due to poor vision, the nurse should suggest a referral to home care services. Home care provides various support services, including assistance with insulin administration. In this scenario, a home care nurse can prefill a week's supply of syringes with the correct insulin dose for the client. These syringes can be stored in the client's refrigerator for self-administration. Occupational therapy focuses on helping individuals with activities of daily living, such as using adaptive devices. Social services typically address counseling and financial aspects of care. Physical therapy is geared towards treating physical disabilities or impairments through exercises and techniques.
5. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?
- A. 2 liters/minute
- B. 4 liters/minute
- C. 6 liters/minute
- D. 8 liters/minute
Correct answer: C
Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.
