Nursing Elites

1. During the first 24 hours after the thermal injury, you should assess Sergio for:

• A. hypokalemia and hypernatremia
• B. hypokalemia and hyponatremia
• C. hyperkalemia and hyponatremia
• D. hyperkalemia and hypernatremia

Correct answer: D

Rationale: During the initial phase after a thermal injury, the major concern is the release of potassium due to cell damage, leading to hyperkalemia. Hypernatremia is not typically a primary concern in the immediate post-injury phase. Hyponatremia is less likely to occur initially after a burn injury. Therefore, the correct assessment for Sergio during the first 24 hours after the thermal injury would be hyperkalemia and hypernatremia.

2. What is the most effective way to limit the number of microorganisms in the hospital?

• A. Using strict aseptic technique in all procedures
• B. Wearing a mask and gown when caring for all patients with communicable diseases
• C. Sterilizing all instruments
• D. Handwashing

Correct answer: A

Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.

3. 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.

4. A client taking antibiotics develops diarrhea. Which of the following foods should the nurse recommend to include in the client’s diet?

• A. Whole wheat bread
• B. Fresh orange sections
• C. Ice cream
• D. Yogurt

Correct answer: D

Rationale: Yogurt is the correct answer because it contains probiotics that can help restore normal gut flora and reduce antibiotic-associated diarrhea. Whole wheat bread (Choice A) may worsen diarrhea due to its high fiber content. Fresh orange sections (Choice B) are acidic and may irritate the digestive system further. Ice cream (Choice C) is high in sugar and fat, which can exacerbate diarrhea.

5. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.
