Nursing Elites

1. The client is discussing sources of carbohydrates with a nurse recently diagnosed with diabetes. Which food(s) identified by the client indicate understanding? (SATA)

• A. Starch
• B. Fiber
• C. Sugar
• D. All of the above

Correct answer: D

Rationale: The correct answer is D because starch, fiber, and sugar are all sources of carbohydrates. Starchy foods like bread, rice, and potatoes contain starch; fruits, vegetables, and whole grains provide fiber; and sugars are found in sweet foods like fruits, honey, and desserts. Fatty acids and amino acids are not sources of carbohydrates, so choices A, B, and C are correct while choices A and B are incorrect.

2. Which of the following body processes is not dependent upon the presence of calcium in the body fluids?

• A. blood clotting
• B. transport of oxygen in the blood
• C. muscle contractions
• D. transmission of nerve impulses

Correct answer: B

Rationale: The transport of oxygen in the blood is carried out by hemoglobin, which does not require calcium; instead, calcium is essential for blood clotting, muscle contraction, and nerve transmission.

3. A nurse is preparing a teaching plan for a client who has neutropenia as a result of radiation therapy for the treatment of lung cancer. Which of the following should the nurse plan to include in the teaching?

• A. Bottled water is an appropriate choice to increase fluid intake.
• B. The salad bar is a healthy choice when dining out.
• C. Soft-boiled eggs are an appropriate source of protein.
• D. Eating at a buffet is a good choice to increase caloric intake.

Correct answer: A

Rationale: In neutropenia, which is a low count of neutrophils, the client is at a high risk of infection. It is crucial to emphasize the importance of proper hydration to maintain overall health. Bottled water is a safe choice as it reduces the risk of exposure to contaminants that could further compromise the client's immune system. The other options, like the salad bar, soft-boiled eggs, and eating at a buffet, may not be suitable for a client with neutropenia due to the risk of bacterial contamination or exposure to pathogens that could lead to infections, which should be avoided.

4. How many calories does one pound of fat equal?

• A. 1500 calories
• B. 2500 calories
• C. 3500 calories
• D. 5000 calories

Correct answer: C

Rationale: One pound of body fat is equivalent to approximately 3500 calories. This is a generally accepted caloric value used in nutrition and weight management. It's important to note that this is an estimation and individual variations may occur. Choice A (1500 calories), Choice B (2500 calories), and Choice D (5000 calories) are incorrect because they do not match the generally accepted caloric value of 3500 calories for one pound of body fat.

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.
