Nursing Elites

1. Which individual is at greatest risk for developing hypertension?

• A. 45-year-old African-American attorney
• B. 60-year-old Asian-American shop owner
• C. 40-year-old Caucasian nurse
• D. 55-year-old Hispanic teacher

Correct answer: A

Rationale: African-Americans have a higher risk of developing hypertension compared to other ethnic groups. They tend to develop high blood pressure at younger ages and are more sensitive to salt, which increases their risk of hypertension. Additionally, studies have shown that African-Americans may respond differently to hypertensive drugs. Therefore, the 45-year-old African-American attorney is at the greatest risk for developing hypertension. The other choices do not specify factors that put them at a higher risk for hypertension compared to African-Americans.

2. A patient experiences a chest wall contusion as a result of being struck in the chest with a baseball bat. The emergency department nurse would be most concerned if which finding is observed during the initial assessment?

• A. Paradoxic chest movement
• B. Complaint of chest wall pain
• C. Heart rate of 110 beats/minute
• D. Large bruised area on the chest

Correct answer: A

Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.

3. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?

• A. Fats
• B. Zinc
• C. Protein
• D. Calcium

Correct answer: D

Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.

4. The laboratory has just called with the arterial blood gas (ABG) results on four patients. Which result is most important for the nurse to report immediately to the health care provider?

• A. pH 7.34, PaO2 82 mm Hg, PaCO2 40 mm Hg, and O2 sat 97%
• B. pH 7.35, PaO2 85 mm Hg, PaCO2 45 mm Hg, and O2 sat 95%
• C. pH 7.46, PaO2 90 mm Hg, PaCO2 32 mm Hg, and O2 sat 98%
• D. pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%

Correct answer: D

Rationale: The correct answer is D: pH 7.31, PaO2 91 mm Hg, PaCO2 50 mm Hg, and O2 sat 96%. These ABG results indicate uncompensated respiratory acidosis, a critical condition that requires immediate attention. In respiratory acidosis, there is an excess of carbon dioxide in the blood, leading to a decrease in pH. The other options present normal or near-normal ABG values, indicating adequate oxygenation and ventilation. Therefore, these values would not be as urgent to report compared to the patient with respiratory acidosis in option D.

5. The clinic nurse is assessing jaundice in a child with hepatitis. Which anatomical area would provide the best data regarding the presence of jaundice?

• A. The nail beds.
• B. The skin in the sacral area.
• C. The skin in the abdominal area.
• D. The membranes in the ear canal.

Correct answer: A

Rationale: Jaundice, if present, can be best assessed in areas such as the sclera, nail beds, and mucous membranes due to the yellowing of these tissues. The nail beds specifically provide a good indication of jaundice. The skin in the sacral area (Option B) is not typically the best area for assessing jaundice as it is less visible and not as reliable as the nail beds. The skin in the abdominal area (Option C) may show generalized jaundice, but the nail beds are more specific for detecting early signs. Lastly, assessing the membranes in the ear canal (Option D) is not a standard method for evaluating jaundice; the sclera and nail beds are more commonly used for this purpose.
