Nursing Elites

1. A nurse is developing a program about strategies to prevent foodborne illnesses for a community group. The nurse should plan to include which of the following recommendations? (Select one that does not apply).

• A. Keep cold food temperatures below 4.4�C (40�F).
• B. Reheat leftovers before eating.
• C. Wash raw vegetables thoroughly in clean water.
• D. Keep cooked foods at 48.9�C (120�F).

Correct answer: D

Rationale: The correct answer is to keep cooked foods at 48.9�C (120�F). This temperature is too low to keep cooked foods safe from bacterial growth. The ideal temperature to keep cooked foods safe is above 60�C (140�F). Choices A, B, and C are all important strategies to prevent foodborne illnesses. Keeping cold food temperatures below 4.4�C (40�F) helps prevent bacterial growth, reheating leftovers before eating kills any bacteria that may have grown during storage, and washing raw vegetables thoroughly in clean water helps remove dirt and bacteria.

2. What is the major diet-derived antioxidant found in cell membranes?

• A. B12
• B. beta-carotene
• C. vitamin E
• D. vitamin A

Correct answer: C

Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.

3. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?

• A. A client who is postoperative following a laminectomy and is receiving IV PCA
• B. A client who has dysphagia and does not recognize his family
• C. A client who has COPD and is going home with oxygen
• D. A client who has colon cancer and will undergo a hemicolectomy

Correct answer: D

Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.

4. What percentage of body weight as fat does a woman with a healthy body composition typically average?

• A. 5%
• B. 15%
• C. 25%
• D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

5. High blood pressure is defined as systolic and diastolic measurements greater than or equal to:

• A. 140 mm Hg and 90 mm Hg, respectively
• B. 150 mm Hg and 80 mm Hg, respectively
• C. 160 mm Hg and 110 mm Hg, respectively
• D. 180 mm Hg and 120 mm Hg, respectively

Correct answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.
