A client with a history of chronic kidney disease (CKD) is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?
- A. Serum potassium level
- B. White blood cell count
- C. Hemoglobin level
- D. Serum calcium level
Correct Answer: A
Rationale: The correct answer is A: Serum potassium level. In a client receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increased demand for potassium. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because erythropoietin therapy specifically impacts potassium levels, not white blood cell count, hemoglobin level, or serum calcium level.

A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?
- A. Serum glucose of 300 mg/dl
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum sodium of 135 mEq/L
Correct Answer: C
Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DKA). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.
A client with a spinal cord injury at the T1 level is admitted with a suspected deep vein thrombosis (DVT) in the right leg. Which intervention should the nurse implement first?
- A. Administer prescribed anticoagulant therapy
- B. Place the client on bedrest
- C. Elevate the client's right leg
- D. Apply compression stockings to the right leg
Correct Answer: B
Rationale: The correct answer is to place the client on bedrest. Placing the client on bedrest is the priority intervention as it helps prevent the risk of embolization from the DVT, which could lead to a life-threatening pulmonary embolism. Administering anticoagulant therapy, elevating the client's right leg, or applying compression stockings are important interventions in managing DVT but should come after ensuring the client is on bedrest to prevent the dislodgment of the clot.
An older female client tells the nurse that her muscles have gradually been getting weaker. What is the best initial response by the nurse?
- A. Explain that this is an expected occurrence with aging.
- B. Observe the lower extremities for signs of muscle atrophy.
- C. Review the medical record for recent diagnostic test results.
- D. Ask the client to describe the changes that have occurred.
Correct Answer: D
Rationale: The best initial response by the nurse when the client reports muscle weakness is to ask the client to describe the changes that have occurred. This approach allows the nurse to gain a better understanding of the client's experience, the extent of weakness, any associated symptoms, and potential triggers. By actively listening to the client's description, the nurse can gather valuable information that will aid in a comprehensive assessment and development of a tailored care plan. Choice A is incorrect because assuming muscle weakness is solely due to aging without further assessment can lead to overlooking potential underlying causes. Choice B is incorrect as observing for signs of muscle atrophy should come after gathering information directly from the client. Choice C is incorrect as reviewing diagnostic test results should not be the initial step when the client's current experience is being shared.
While taking vital signs, a critically ill male client grabs the nurse's hand and asks the nurse not to leave. What action is best for the nurse to take?
- A. Pull up a chair and sit beside the client's bed.
- B. Reassure the client that you will return shortly.
- C. Ask another nurse to stay with the client.
- D. Continue taking vital signs and then leave the room.
Correct Answer: A
Rationale: The best action for the nurse to take in this situation is to pull up a chair and sit beside the client's bed. By doing so, the nurse can provide emotional support and comfort to the critically ill patient who is feeling vulnerable. Sitting with the client also shows empathy and a willingness to listen to the client's needs. Reassuring the client that the nurse will return shortly (Choice B) may not address the immediate need for emotional support. Asking another nurse to stay with the client (Choice C) may not establish the same level of connection and comfort as sitting with the client personally. Continuing to take vital signs and then leaving the room (Choice D) disregards the client's emotional needs in that moment.
A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dL
- B. Serum glucose of 600 mg/dL
- C. Serum potassium of 5.5 mEq/L
- D. Serum bicarbonate of 18 mEq/L
Correct Answer: D
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.
