Nursing Elites

1. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?

• A. Take your insulin as usual
• B. Do not eat or drink after midnight
• C. Monitor your blood glucose closely
• D. Bring your glucose meter to the hospital

Correct answer: B

Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.

2. The healthcare provider is assessing a client with a suspected diagnosis of appendicitis. Which symptom is most indicative of this condition?

• A. Right upper quadrant pain
• B. Nausea and vomiting
• C. Rebound tenderness at McBurney's point
• D. Hematuria

Correct answer: C

Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This symptom is due to irritation of the peritoneum when pressure is released during palpation. Right upper quadrant pain (Choice A) is more commonly associated with gallbladder issues. Nausea and vomiting (Choice B) can occur in various abdominal conditions and are not specific to appendicitis. Hematuria (Choice D) is the presence of blood in the urine and is not a typical symptom of appendicitis.

3. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

4. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. What is the primary purpose of this medication?

• A. To lower blood pressure
• B. To improve appetite
• C. To increase red blood cell production
• D. To reduce fluid retention

Correct answer: C

Rationale: The correct answer is C: 'To increase red blood cell production.' Erythropoietin stimulates the production of red blood cells to treat anemia associated with CKD. Choices A, B, and D are incorrect because erythropoietin therapy is primarily used to address anemia by increasing the production of red blood cells rather than lowering blood pressure, improving appetite, or reducing fluid retention.

5. The client has chronic renal failure. What dietary modification is most important for this client?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase sodium intake
• D. Encourage dairy products

Correct answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.
