1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which intervention is most important?
- A. Administer intravenous fluids as prescribed.
- B. Monitor the client's urine output.
- C. Administer insulin as prescribed.
- D. Administer 50% dextrose IV push.
Correct answer: C
Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. In DKA, there is a lack of insulin leading to hyperglycemia and ketosis. Insulin administration helps to reduce blood glucose levels and correct metabolic acidosis, which are crucial in treating DKA. Administering intravenous fluids helps with dehydration, monitoring urine output is important to assess renal function, but the priority is addressing the underlying cause of DKA by administering insulin. Administering 50% dextrose IV push is incorrect as it would further elevate blood glucose levels, which is contraindicated in DKA.
3. An adolescent's mother calls the clinic because the teen is having recurrent vomiting and has been combative in the last 2 days. The mother states that the teen takes vitamins, calcium, and magnesium supplements along with aspirin. Which nursing intervention has the highest priority?
- A. Advise the mother to withhold all medications by mouth.
- B. Instruct the mother to take the teen to the emergency room.
- C. Recommend that the teen withhold food and fluids for 2 hours.
- D. Suggest that the adolescent breathe slowly and deeply.
Correct answer: B
Rationale: In this scenario, the highest priority nursing intervention is to instruct the mother to take the teen to the emergency room. The symptoms of recurrent vomiting, combative behavior, and the medications (vitamins, calcium, magnesium supplements, and aspirin) taken by the teen suggest a possible overdose or serious adverse reaction. Therefore, immediate medical evaluation is crucial to assess and manage any potential toxicity or adverse effects. Advising to withhold all medications by mouth (Choice A) may delay necessary treatment. Recommending withholding food and fluids for 2 hours (Choice C) may not address the underlying cause of the symptoms. Suggesting slow and deep breathing (Choice D) is not appropriate in this urgent situation requiring immediate medical attention.
4. During the initial visit, which intervention is most important for the nurse to implement?
- A. Determine how the client is cared for when the caregiver is not present.
- B. Develop a client needs assessment and review it with the caregiver.
- C. Evaluate the caregiver's ability to care for the client's needs.
- D. Review with the caregiver the interventions provided each day.
Correct answer: A
Rationale: The most important intervention for the nurse to implement during the initial visit is to determine how the client is cared for when the caregiver is not present. This is crucial for ensuring continuous and adequate care, especially for a bed-bound client with multiple sclerosis who relies heavily on the caregiver. While developing a client needs assessment (choice B) and evaluating the caregiver's ability (choice C) are important, understanding the care plan in the caregiver's absence takes precedence. Reviewing daily interventions with the caregiver (choice D) is valuable but not as critical as knowing the care plan during the caregiver's absence.
5. The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Prothrombin time (PT)
- C. International Normalized Ratio (INR)
- D. Serum sodium level
Correct answer: C
Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.
