Nursing Elites

1. A client with chronic kidney disease (CKD) is scheduled for a renal biopsy. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Serum creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Before a renal biopsy, the nurse should review the serum creatinine level. Serum creatinine is a key indicator of kidney function. In clients with chronic kidney disease (CKD), monitoring creatinine levels is crucial as elevated levels may indicate worsening kidney function, which could impact the safety and outcome of the biopsy. Hemoglobin (choice C) is important for assessing oxygen-carrying capacity but is not directly related to the kidney biopsy procedure. Serum potassium (choice A) is important to monitor in CKD but is not specifically crucial before a renal biopsy. White blood cell count (choice D) is more relevant for assessing infection or inflammation, which is not the primary concern before a renal biopsy.

2. An adult client comes to the clinic and reports his concern over a lump that 'just popped up on my neck about a week ago.' In performing an examination of the lump, the nurse palpates a large, non-tender, hardened left subclavian lymph node. There is no overlying tissue inflammation. What do these findings suggest?

• A. Malignancy
• B. Infection
• C. Benign cyst
• D. Lymphadenitis

Correct answer: A

Rationale: The findings of a large, non-tender, hardened lymph node, especially in the absence of overlying tissue inflammation, are indicative of malignancy. These characteristics raise suspicion for cancer, prompting the need for further investigation. Choice B, Infection, is incorrect because infection would typically present as a tender and possibly swollen lymph node. Choice C, Benign cyst, is incorrect as cysts are usually soft and movable. Choice D, Lymphadenitis, is incorrect as lymphadenitis usually presents with tender and enlarged lymph nodes in response to an infection.

3. A client with diabetes mellitus is admitted with a blood glucose level of 640 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer IV fluids as prescribed
• C. Check the client's blood glucose level
• D. Prepare the client for immediate dialysis

Correct answer: B

Rationale: Administering IV fluids as prescribed is the priority intervention in a client with a blood glucose level of 640 mg/dl and unresponsiveness. Severe hyperglycemia can lead to dehydration and electrolyte imbalances, and administering IV fluids can help manage hyperglycemia and prevent further complications. Administering dextrose IV push (Choice A) can exacerbate hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the immediate priority when the client is unresponsive. Immediate dialysis (Choice D) is not indicated as the first intervention for hyperglycemia.

4. The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which intervention should the nurse implement first?

• A. Encourage fluid intake to thin secretions.
• B. Administer a mucolytic agent.
• C. Increase humidity in the client's room.
• D. Perform deep suctioning as needed.

Correct answer: C

Rationale: Increasing humidity in the client's room is the first priority in managing thick, tenacious secretions in a client with a tracheostomy to facilitate airway clearance. This intervention helps to moisten secretions, making them easier to clear. Encouraging fluid intake (Choice A) can be beneficial, but increasing humidity should be addressed first. Administering a mucolytic agent (Choice B) and performing deep suctioning (Choice D) are interventions that can be considered after addressing humidity if necessary, but they are not the initial priority.

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.
