Nursing Elites

1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

2. The client with hypertension is being taught about lifestyle changes. Which recommendation is most important to include?

• A. Increase sodium intake
• B. Engage in regular physical activity
• C. Consume a diet high in saturated fats
• D. Limit fluid intake

Correct answer: B

Rationale: Engaging in regular physical activity is crucial for managing hypertension as it helps lower blood pressure. Regular exercise can improve heart health, increase circulation, and contribute to overall well-being, all of which are beneficial for individuals with hypertension. Choice A, increasing sodium intake, is incorrect as reducing sodium is recommended for hypertension to help lower blood pressure. Choice C, consuming a diet high in saturated fats, is incorrect as a diet high in saturated fats can negatively impact blood pressure and cardiovascular health. Choice D, limiting fluid intake, is incorrect as maintaining adequate hydration is important for overall health and not directly related to hypertension management.

3. 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.

4. A client with a history of hypertension is prescribed lisinopril. Which potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperglycemia
• C. Persistent cough
• D. Tachycardia

Correct answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.

5. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?

• A. Jaundice.
• B. Ascites.
• C. Spider angiomas.
• D. Asterixis.

Correct answer: D

Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
