A nurse is caring for a client who has acute kidney injury and a potassium level of 6.5 mEq/L. Which of the following ECG changes should the nurse expect?
- A. Flattened T waves
- B. Peaked T waves
- C. Prolonged PR interval
- D. ST segment depression
Correct Answer: B
Rationale: The correct answer is B: Peaked T waves. In hyperkalemia (high potassium level), the myocardium becomes more excitable, leading to changes in the ECG. Peaked T waves are a classic sign of hyperkalemia, indicating early stages of cardiac involvement. Flattened T waves (choice A) are associated with hypokalemia. Prolonged PR interval (choice C) and ST segment depression (choice D) are not typically seen in hyperkalemia.

A nurse is preparing a teaching plan for a client who is starting to receive hemodialysis for chronic kidney disease. Which of the following instructions should the nurse include in the teaching?
- A. Increase your intake of protein to 1 to 1.5 grams per kilogram per day.
- B. Reduce your fluid intake to 1L per day.
- C. Increase sodium intake to prevent hypotension.
- D. Monitor blood glucose levels daily.
Correct Answer: A
Rationale: The correct answer is A: Increase your intake of protein to 1 to 1.5 grams per kilogram per day. This is because patients undergoing hemodialysis often experience protein loss during the process. Adequate protein intake helps maintain muscle mass and supports overall health. Option B is incorrect as fluid restriction is typically recommended for patients on hemodialysis due to impaired fluid removal by the kidneys. Option C is incorrect as increasing sodium intake can lead to fluid retention and exacerbate hypertension, a common complication in chronic kidney disease. Option D is not directly related to hemodialysis and is more pertinent to diabetes management.
A nurse is caring for a client who has a new diagnosis of type 1 diabetes mellitus. Which of the following findings should the nurse identify as a manifestation of type 1 diabetes?
- A. Ketones in the urine
- B. Weight gain
- C. Hypotension
- D. Decreased hunger
Correct Answer: A
Rationale: The correct answer is A: Ketones in the urine. In type 1 diabetes, the body cannot produce insulin, leading to high blood sugar levels and breakdown of fats for energy, resulting in ketones in the urine. Weight gain (B) is unlikely as type 1 diabetes is associated with weight loss. Hypotension (C) is not a typical manifestation. Decreased hunger (D) is more commonly seen in type 2 diabetes.
A nurse is assessing a clients understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?
- A. Proceed with obtaining the signature.
- B. Explain the procedure in detail.
- C. Contact the provider who will be performing the procedure.
- D. Have the client sign the form and address concerns later.
Correct Answer: C
Rationale: The correct answer is C: Contact the provider who will be performing the procedure. This is the best course of action because the provider is the most qualified individual to explain the procedure in detail and address any concerns the client may have. By involving the provider, the client can receive accurate and comprehensive information directly from the source. Proceeding with obtaining the signature (A) without ensuring the client's understanding can lead to potential legal and ethical issues. Explaining the procedure in detail (B) may not be sufficient if the client still has questions or concerns. Having the client sign the form and addressing concerns later (D) is not appropriate as it prioritizes paperwork over patient understanding and safety.
A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available is potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number.)
- A. 50 mL/hr
- B. 75 mL/hr
- C. 100 mL/hr
- D. 125 mL/hr
Correct Answer: C
Rationale: To calculate the infusion rate, we need to use the formula: (Desired dose ÷ Volume) x 60 minutes. In this case, the desired dose is 10 mEq over 1 hour, and the volume is 100 mL.
So, (10 ÷ 100) x 60 = 6 mL/hr. Therefore, the nurse should set the infusion pump to deliver 100 mL/hr. This ensures the correct administration of potassium chloride over the specified time frame.
Choice A (50 mL/hr) and B (75 mL/hr) are incorrect as they would result in the underdosing of potassium chloride. Choice D (125 mL/hr) is incorrect as it would result in the overdosing of potassium chloride. The correct answer, C (100 mL/hr), ensures the proper administration of the medication within the specified parameters.
A nurse is caring for a client who has multiple leg fractures and is 24 hr postoperative following placement of skeletal traction. Which of the following actions should the nurse take?
- A. Inspect the pin sites at least every 8 hr.
- B. Apply direct pressure to pin sites.
- C. Remove traction weights for comfort.
- D. Encourage vigorous movement of the affected limb.
Correct Answer: A
Rationale: Correct Answer: A. Inspect the pin sites at least every 8 hr.
Rationale:
1. Inspecting pin sites regularly is crucial to monitor for signs of infection or other complications.
2. Postoperative clients with skeletal traction are at high risk for pin site infections.
3. Regular inspection allows early detection and intervention to prevent complications.
4. Waiting longer than every 8 hours may lead to delayed identification of issues.
Summary:
B. Applying direct pressure is contraindicated as it can cause harm.
C. Removing traction weights without medical order can lead to complications.
D. Encouraging vigorous movement is inappropriate and can cause harm.
