Nursing Elites

1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning to the nurse?

• A. Serum glucose of 500 mg/dL
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS) as it indicates severe dehydration and hypertonicity. This high serum osmolarity level can lead to neurological complications and requires immediate intervention to prevent further deterioration. Serum glucose levels, blood pressure, and serum pH are important parameters to monitor in HHS, but a significantly elevated serum osmolarity poses a higher risk of complications and warrants urgent attention. High serum glucose levels, like 500 mg/dL, are expected in HHS but do not directly indicate the severity of dehydration. Blood pressure of 140/90 mmHg is within normal limits and may not be directly related to the acute complications of HHS. A serum pH of 7.30 suggests acidosis, which is important to address but may not be as immediately concerning as severe dehydration indicated by high serum osmolarity.

2. Following an open reduction of the tibia, the nurse notes bleeding on the client's cast. Which action should the nurse implement?

• A. Outline the area with ink and check it every 15 minutes to see if the area has increased
• B. Notify the healthcare provider immediately
• C. Apply a new cast to stop the bleeding
• D. Elevate the limb to reduce blood flow

Correct answer: A

Rationale: After an open reduction of the tibia, bleeding on the cast can be a concern. Outlining the area with ink and monitoring it every 15 minutes is the appropriate action to assess if the bleeding is worsening, indicating the need for further intervention. This action allows for close observation without disturbing the cast. Choice B is incorrect because while notifying the healthcare provider is important, immediate action is not always necessary if the bleeding is not severe. Choice C is incorrect because applying a new cast is not the standard intervention for bleeding on a cast. Choice D is incorrect because elevating the limb may not address the underlying cause of bleeding and may not be the most appropriate action at this time.

3. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be monitored closely?

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

Correct answer: A

Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is undergoing erythropoietin therapy, monitoring serum potassium levels is crucial. Erythropoietin can stimulate red blood cell production, which may lead to an increase in potassium levels, predisposing the client to hyperkalemia. Monitoring serum potassium levels helps in early detection of hyperkalemia and appropriate intervention. Choices B, C, and D are incorrect because although hemoglobin, serum sodium, and white blood cell count are important parameters to monitor in various clinical conditions, they are not specifically associated with erythropoietin therapy in chronic kidney disease.

4. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider before the procedure?

• A. Serum potassium of 5.5 mEq/L
• B. Hemoglobin of 10 g/dl
• C. Potassium of 6.0 mEq/L
• D. Blood glucose of 200 mg/dl

Correct answer: C

Rationale: The correct answer is C: Potassium of 6.0 mEq/L. A potassium level of 6.0 mEq/L is dangerously high in a client with CKD, and it should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Choices A, B, and D are not the most critical values to report before hemodialysis. While a serum potassium level of 5.5 mEq/L is slightly elevated, it is not as urgent as a level of 6.0 mEq/L in this context. Hemoglobin of 10 g/dl and blood glucose of 200 mg/dl are important parameters to monitor but are not as immediately concerning before hemodialysis compared to a high potassium level.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
