Nursing Elites

1. What ECG changes are seen in hypokalemia?

• A. Flattened T waves on the ECG
• B. Elevated ST segments on the ECG
• C. Widened QRS complex
• D. Prominent U waves on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

2. A nurse is teaching a client who has type 1 DM about hypoglycemia. Which of the following statements by the client indicates an understanding of the teaching?

• A. Exercise reduces the risk for hypoglycemia.
• B. I can skip my insulin when I don't eat.
• C. I can drink 4 oz of soda if my blood sugar is low.
• D. Diabetic pills don't cause hypoglycemia; only insulin does.

Correct answer: C

Rationale: The client can correct any development of hypoglycemia with a quick intake of glucose. The client should have 15 g carbohydrates on hand to treat hypoglycemic episodes, like 4 oz of regular soda.

3. What are the early signs of compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and infection
• D. Loss of sensation in the affected area

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. These signs are typical early indicators of compartment syndrome, suggesting compromised circulation. Choice B, localized redness and swelling, can be seen in conditions like cellulitis but are not specific to compartment syndrome. Choice C, fever and infection, are not characteristic early signs of compartment syndrome. Choice D, loss of sensation in the affected area, is more indicative of nerve damage rather than being one of the early signs of compartment syndrome.

4. A nurse is planning care for a client who has acute post-streptococcal glomerulonephritis. Which of the following interventions should the nurse include in the client's plan?

• A. Encourage a high-protein diet
• B. Increase the client's fluid intake
• C. Administer diuretics
• D. Weigh the client twice a week

Correct answer: C

Rationale: Administering diuretics is a crucial intervention for a client with acute post-streptococcal glomerulonephritis as it helps reduce edema by increasing urine output and managing symptoms of glomerulonephritis. Encouraging a high-protein diet (Choice A) is not recommended in this case because it can put additional stress on the kidneys. Increasing fluid intake (Choice B) may worsen edema in these clients. Weighing the client twice a week (Choice D) is important for monitoring fluid balance but is not as immediate and directly beneficial as administering diuretics.

5. What ECG changes are seen with hyperkalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.
