Nursing Elites

1. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

• A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
• B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• C. An infusion of medication in the spinal canal will block pain perception
• D. The discharge of electricity will distract the client's focus on the pain

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

2. The nurse is caring for a 75-year-old male client who is beginning to form a decubitus ulcer at the coccyx. Which intervention will be most helpful in preventing further development of the decubitus ulcer?

• A. Encourage the client to eat foods high in protein
• B. Assess the client for daily range of motion exercises
• C. Teach the family how to perform sterile wound care
• D. Ensure the IV fluids are administered as prescribed

Correct answer: A

Rationale: Encouraging the client to eat foods high in protein is crucial in preventing further development of decubitus ulcers as high protein foods support tissue repair and skin integrity. Adequate protein intake is essential for wound healing. Assessing the client for daily range of motion exercises is important for preventing complications related to immobility, but it may not directly address the prevention of decubitus ulcers. Teaching the family how to perform sterile wound care is significant for wound management but may not be the most effective intervention to prevent further development of decubitus ulcers. Ensuring IV fluids are administered as prescribed is essential for maintaining hydration status but is not the most relevant intervention for preventing decubitus ulcers.

3. A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?

• A. Hemoglobin 9.5 g/dL
• B. Potassium 6.2 mEq/L
• C. Creatinine 3.5 mg/dL
• D. BUN 50 mg/dL

Correct answer: B

Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.

4. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?

• A. Take your insulin as usual
• B. Do not eat or drink after midnight
• C. Monitor your blood glucose closely
• D. Bring your glucose meter to the hospital

Correct answer: B

Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.

5. The nurse is caring for a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct answer: D

Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.
