Nursing Elites

1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value requires immediate intervention?

• A. Serum glucose of 600 mg/dL
• B. Serum osmolarity of 320 mOsm/kg
• C. Serum sodium of 130 mEq/L
• D. Serum potassium of 5.0 mEq/L

Correct answer: B

Rationale: A serum osmolarity of 320 mOsm/kg is concerning in a client with HHS because it indicates severe dehydration and hyperosmolarity, which requires immediate intervention. In HHS, the elevated serum osmolarity leads to neurological symptoms and can result in serious complications if not addressed promptly. While a high serum glucose level (choice A) is typical in HHS, the osmolarity is a more direct indicator of dehydration and severity. Serum sodium (choice C) and potassium levels (choice D) are important but do not pose an immediate threat to the client's condition compared to the severe hyperosmolarity indicated by a high serum osmolarity level.

2. 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.

3. 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.

4. A client with rapid respirations and audible rhonchi is admitted to the intensive care unit because of a pulmonary embolism (PE). Low-flow oxygen by nasal cannula and weight-based heparin protocol are initiated. Which intervention is most important for the nurse to include in this client's plan of care?

• A. Evaluate blood clotting factors daily.
• B. Encourage incentive spirometry use.
• C. Administer pain medication as needed.
• D. Monitor for signs of bleeding.

Correct answer: A

Rationale: Evaluating blood clotting factors daily is crucial when a client is on heparin therapy to monitor for potential complications such as bleeding or clotting issues. This monitoring helps ensure that the heparin dose is within the therapeutic range and reduces the risk of bleeding or clotting complications. Encouraging incentive spirometry use is beneficial for preventing atelectasis and improving lung function, but in this scenario, monitoring blood clotting factors takes precedence. Administering pain medication as needed is important for the client's comfort but is not the priority in managing a pulmonary embolism. Monitoring for signs of bleeding is important due to heparin therapy, but evaluating blood clotting factors provides more specific information on the client's response to treatment.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?

• A. INR of 3.0
• B. Prothrombin time (PT) of 15 seconds
• C. Hemoglobin of 10 g/dl
• D. White blood cell count

Correct answer: A

Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.
