1. Which nutrient is most important for maintaining fluid balance in the body?

• A. Protein
• B. Sodium
• C. Calcium

Rationale: Sodium plays a key role in maintaining fluid balance and regulating blood pressure.

2. Of the foods listed, the best source of phosphorus is?

• A. lettuce
• B. pears
• C. chicken
• D. noodles

Correct answer: C

Rationale: Chicken is a good source of phosphorus, which is essential for bone health and energy production in the body.

3. What are the responsibilities of a nurse towards a patient?

• A. A registered nurse is responsible for a group of patients from their admission to their discharge
• B. A registered nurse only provides care for the patient with the assistance of nursing aides
• C. A nurse's only responsibility is to perform administrative duties in a healthcare setting
• D. A nurse's only responsibility is to maintain hospital equipment

Correct answer: A

Rationale: A registered nurse is responsible for a group of patients from their admission to their discharge. This responsibility encompasses assessing patient needs, formulating care plans, administering medications, monitoring patient progress, and coordinating with other members of the healthcare team. Choice B is not entirely accurate because, even though nurses often work with nursing aides, the nurses themselves hold the ultimate responsibility for the overall care of the patient. Choices C and D are incorrect as they depict an incomplete and inaccurate representation of a nurse's role, which extends beyond administrative duties and equipment maintenance to primarily focus on direct patient care.

4. A client is being taught about following a low-cholesterol diet after coronary artery bypass grafting. Which of the following food choices reflects the client's understanding of these dietary instructions?

• A. Liver
• B. Milk
• C. BEANS
• D. Eggs

Correct answer: C

Rationale: Choosing beans as a food option indicates that the client understands the low-cholesterol diet instructions. Beans are a good source of fiber and plant-based protein, which can help lower cholesterol levels. On the other hand, liver and eggs are high in cholesterol and should be limited in a low-cholesterol diet. Milk, especially whole milk, can also be high in saturated fats and cholesterol, so it is not the best choice for a low-cholesterol diet.

5. 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.
