Nursing Elites

1. A young adult male is admitted to the emergency department with diabetic ketoacidosis (DKA). His pH is 7.25, HCO3 is 12 mEq/L, and blood glucose is 310 mg/dl. Which action should the nurse implement?

• A. Infuse sodium chloride 0.9% (normal saline)
• B. Prepare an emergency dose of glucagon
• C. Determine the last time the client ate
• D. Check urine for ketone bodies with a dipstick

Correct answer: A

Rationale: In DKA, restoring fluid balance with sodium chloride is a priority to address the dehydration and electrolyte imbalances present in this condition. Choice B, preparing an emergency dose of glucagon, is incorrect because DKA is characterized by insulin deficiency, not glucagon deficiency. Choice C, determining the last time the client ate, is not the immediate priority in managing DKA. Choice D, checking urine for ketone bodies with a dipstick, may help confirm the diagnosis of DKA but is not the most critical intervention at this time.

2. 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.

3. When caring for a client with traumatic brain injury (TBI) who had a craniotomy for increased intracranial pressure (ICP), the nurse assesses the client using the Glasgow Coma Scale (GCS) every two hours. For the past 8 hours, the client's GCS score has been 14. What does this GCS finding indicate about the client?

• A. Neurologically stable without indications of increased ICP.
• B. At risk for neurological deterioration.
• C. Experiencing mild cognitive impairment.
• D. In need of immediate medical intervention.

Correct answer: A

Rationale: A GCS score of 14 indicates that the client is neurologically stable without indications of increased ICP. It suggests that the client's neurological status is relatively intact, with only mild impairment, if any. This finding reassures the nurse that there are currently no signs of deterioration or immediate need for intervention. Choice B is incorrect because a GCS score of 14 does not necessarily indicate immediate risk for neurological deterioration. Choice C is incorrect as mild cognitive impairment is not typically inferred from a GCS score of 14. Choice D is incorrect as immediate medical intervention is not warranted based on a GCS score of 14 without other concerning symptoms.

4. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value requires immediate intervention?

• A. Serum ammonia level of 80 mcg/dl
• B. Bilirubin level of 3.0 mg/dl
• C. Serum sodium level of 135 mEq/L
• D. Prothrombin time of 18 seconds

Correct answer: D

Rationale: The correct answer is D. A prothrombin time of 18 seconds is most concerning in a client with hepatic encephalopathy as it indicates impaired liver function and an increased risk of bleeding. This requires immediate intervention to prevent bleeding complications. Choice A, serum ammonia level of 80 mcg/dl, is elevated but not as urgent as the abnormal prothrombin time. Choice B, bilirubin level of 3.0 mg/dl, is elevated but does not directly indicate an urgent need for intervention in this situation. Choice C, serum sodium level of 135 mEq/L, is within the normal range and does not require immediate intervention.

5. A client with a history of type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which intervention is most important?

• A. Administer intravenous fluids as prescribed.
• B. Administer insulin as prescribed.
• C. Monitor the client's urine output.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. Insulin helps to reduce blood glucose levels and correct metabolic acidosis, which are critical in the treatment of DKA. While administering intravenous fluids is essential to manage dehydration, insulin takes precedence in treating the underlying cause of DKA. Monitoring urine output is important for assessing renal function but is not the primary intervention in managing DKA. Checking the client's blood glucose level is necessary, but administering insulin to reduce high blood glucose levels is the key priority in treating DKA.
