1. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

2. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

3. 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.

4. A nurse is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?

• A. I can expect swelling in my hands and on my face.
• B. The amount of protein in my blood is high.
• C. I might have some pain and gas in my stomach from this condition.
• D. I will use a soft bristle toothbrush to prevent bleeding gums.

Correct answer: A

Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.

5. A nurse is teaching a client who has hypertension about dietary modifications to help control blood pressure. Which of the following food choices should the nurse recommend as the best choice for the client to include in their diet?

• A. 1 packet of reconstituted dry onion soup
• B. 3 oz of lean cured ham
• C. 3 oz of chicken breast
• D. ½ cup of canned baked beans

Correct answer: C

Rationale: For a client with hypertension, a low sodium diet is recommended to help control blood pressure. Among the food choices provided, the best option is 3 oz of chicken breast. Chicken breast is lean protein with lower sodium content compared to other choices. It is a healthier option for managing hypertension. Reconstituted dry onion soup (Choice A) and canned baked beans (Choice D) typically contain higher amounts of sodium, which can be detrimental for blood pressure management. Lean cured ham (Choice B) also tends to have a higher sodium content, making it less suitable for a client with hypertension.
