1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Decreased deep tendon reflexes
- D. Muscle weakness
Correct answer: A
Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.
2. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value is most concerning?
- A. Serum ammonia level of 100 mcg/dl
- B. Bilirubin level of 3.0 mg/dl
- C. Prothrombin time of 18 seconds
- D. Serum sodium level of 135 mEq/L
Correct answer: A
Rationale: A serum ammonia level of 100 mcg/dl is most concerning in a client with hepatic encephalopathy. Elevated serum ammonia levels indicate significant liver dysfunction and an increased risk of worsening encephalopathy. Bilirubin level and prothrombin time are important in assessing liver function, but in the context of hepatic encephalopathy, elevated ammonia levels take precedence as they directly contribute to neurological symptoms. Serum sodium level, though important, is not the primary concern when managing hepatic encephalopathy.
3. After a sudden loss of consciousness, a female client is taken to the ED, and the initial assessment indicates that her blood glucose level is critically low. Once her glucose level is stabilized, the client reports that she was recently diagnosed with anorexia nervosa and is being treated at an outpatient clinic. Which intervention is most important to include in this client's discharge plan?
- A. Describe the signs and symptoms of hypoglycemia.
- B. Encourage a low-carbohydrate and high-protein diet.
- C. Reinforce the need to continue outpatient treatment.
- D. Suggest wearing a medical alert bracelet at all times.
Correct answer: B
Rationale: Encouraging a low-carbohydrate and high-protein diet is crucial for a client recovering from anorexia nervosa to prevent hypoglycemic episodes. Choice A is not the most important intervention at this point since the client is already aware of hypoglycemia based on the recent event. Choice C is important but not the priority in this situation where dietary intervention is crucial. Choice D, suggesting a medical alert bracelet, is not as essential as ensuring proper nutrition to prevent further hypoglycemic episodes.
4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which clinical finding is most concerning to the nurse?
- A. Kussmaul respirations
- B. Blood glucose level of 300 mg/dl
- C. Serum potassium of 3.2 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.
5. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which assessment finding is most concerning?
- A. INR of 3.5
- B. Prothrombin time (PT) of 15 seconds
- C. Headache
- D. Blood pressure of 140/90 mmHg
Correct answer: C
Rationale: The correct answer is C. A headache in a client with a history of atrial fibrillation receiving warfarin (Coumadin) is concerning as it may indicate bleeding, which requires immediate assessment and intervention. Headaches can be a symptom of increased intracranial pressure due to bleeding, especially in patients on anticoagulants. Options A and B are within acceptable ranges for a client on warfarin therapy, indicating that the medication is effectively managing the clotting times. Option D, a blood pressure of 140/90 mmHg, while elevated, is not directly related to the client's condition of atrial fibrillation and warfarin therapy.
