1. 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.

2. Patients maintained using peritoneal dialysis may gain weight because:

• A. their appetite is increased
• B. physical activity is limited
• C. they absorb glucose from the dialysate
• D. they absorb amino acids from the dialysate

Correct answer: C

Rationale: Glucose from the peritoneal dialysis solution can be absorbed into the bloodstream, leading to weight gain if not balanced with diet and activity.

3. The PEM in which children ages 18-24 months display edema of the extremities, torso, and face, fatty liver, sparse yellow hair, and receive adequate kilocalories but not enough high-quality proteins is called?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: B

Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.

4. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.

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.
