1. What is the most important nursing intervention for a patient with increased intracranial pressure (ICP)?

• A. Elevate the head of the bed to 30 degrees.
• B. Administer diuretics to reduce fluid volume.
• C. Administer corticosteroids to reduce inflammation.
• D. Keep the patient in a supine position.

Correct answer: A

Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.

2. A client with cardiovascular disease is scheduled to receive a daily dose of furosemide (Lasix). Which potassium level would cause the nurse to contact the physician before administering the dose?

• A. 3.0 mEq/L
• B. 3.8 mEq/L
• C. 4.2 mEq/L
• D. 5.1 mEq/L

Correct answer: A

Rationale: The normal serum potassium level in adults ranges from 3.5 to 5.1 mEq/L. A potassium level of 3.0 mEq/L is low, indicating hypokalemia and necessitating physician notification before administering furosemide, a loop diuretic that can further lower potassium levels. Potassium levels of 3.8 and 4.2 mEq/L are within the normal range, while a level of 5.1 mEq/L is high (hyperkalemia), but the critical value in this case is the low potassium level that requires immediate attention to prevent potential complications.

3. In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?

• A. Polyuria
• B. Bradycardia
• C. Dry skin
• D. Tachycardia

Correct answer: D

Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.

4. Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?

• A. Fasting blood glucose levels.
• B. Postprandial blood glucose levels.
• C. Hemoglobin A1c.
• D. Random blood glucose levels.

Correct answer: C

Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

5. In a patient with chronic kidney disease, which of the following lab values would be expected?

• A. Elevated creatinine levels.
• B. Low hemoglobin levels.
• C. Elevated potassium levels.
• D. Low sodium levels.

Correct answer: A

Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.
