Nursing Elites

1. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

2. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?

• A. A client who is postoperative following a laminectomy and is receiving IV PCA
• B. A client who has dysphagia and does not recognize his family
• C. A client who has COPD and is going home with oxygen
• D. A client who has colon cancer and will undergo a hemicolectomy

Correct answer: D

Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.

3. A client receiving chemotherapy treatments tells the nurse, 'I feel so nauseated after my treatments.' Which of the following instructions should the nurse provide the client?

• A. Eat common foods that are served cold.
• B. Sip fluids slowly throughout the day.
• C. Sit up for 1 hr after eating meals.
• D. All of the Above

Correct answer: D

Rationale: The correct answer is D, 'All of the Above.' Common foods served cold, sipping fluids slowly throughout the day, and sitting up for 1 hr after eating meals can help manage nausea associated with chemotherapy. Eating common foods served cold can be easier on the stomach, sipping fluids slowly can prevent overwhelming the digestive system, and sitting up after meals can aid digestion. Choices A, B, and C all contribute to alleviating nausea and are appropriate instructions for the client.

4. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

• A. Calcium
• B. Folate
• C. Vitamin A
• D. Choline

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

5. Which student lunch is the least nutritious?

• A. Ham sandwich, apple, and milk
• B. Hamburger, fries, and soft drink
• C. Macaroni and cheese, green beans, and peaches
• D. Meatloaf, broccoli, and pear slices

Correct answer: B

Rationale: The correct answer is B - 'Hamburger, fries, and soft drink' as it contains foods high in unhealthy fats, sugars, and low nutritional value. A hamburger, fries, and a soft drink are considered less nutritious compared to the other options. Choice A includes a ham sandwich, apple, and milk, which provide a balance of protein, fiber, and calcium. Choice C consists of macaroni and cheese, green beans, and peaches, offering a mix of carbohydrates, vegetables, and fruits. Choice D contains meatloaf, broccoli, and pear slices, which provide a good source of protein, vitamins, and fiber. Therefore, option B is the least nutritious among the given choices.
