Nursing Elites

1. Which type of lipid is solid at room temperature?

• A. Cholesterol
• B. Phospholipid
• C. Saturated fat
• D. Trans fat

Correct answer: C

Rationale: Saturated fats, such as those found in butter and lard, are typically solid at room temperature due to the lack of double bonds, which allows the fat molecules to pack closely together. Cholesterol (Choice A) is a steroid, not a fat, and while it's solid at room temperature, it doesn't fit the general category of 'lipid' in the context of this question. Phospholipids (Choice B) are a major component of all cell membranes and can be both solid and liquid at room temperature depending on their composition. Trans fats (Choice D) can also be solid or liquid at room temperature, but they are not typically referred to as 'lipids' in a general sense.

2. To prevent injury and strain on the muscles, the nurse should observe proper body mechanics. Among the following, which is a principle of proper body mechanics?

• A. Broaden the space between the feet
• B. Push instead of pull
• C. Move the object away from the body when lifting
• D. Bend at the waist, not on the knees

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. 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.

4. Scurvy is caused by a deficiency of which vitamin?

• A. Vitamin A
• B. Vitamin D
• C. Vitamin E
• D. Vitamin K

Correct answer: C

Rationale: Scurvy is caused by a deficiency of vitamin C, not vitamin E. The symptoms of scurvy include spontaneous gingival hemorrhaging, perifollicular petechiae, follicular hyperkeratosis, diarrhea, fatigue, depression, and cessation of bone growth. Vitamin A (Choice A) is important for vision and immune function, Vitamin D (Choice B) is essential for bone health, and Vitamin K (Choice D) is necessary for blood clotting. However, none of these vitamins are associated with scurvy.

5. A nurse is providing preventative information to a group of parents with toddlers about choking. Which food item should the nurse recommend for this age group?

• A. Banana slices
• B. Popcorn
• C. Hot dogs
• D. Carrot sticks

Correct answer: A

Rationale: Banana slices are the most suitable food option for toddlers to prevent choking. Toddlers are at a higher risk of choking due to their small airways and developing chewing abilities. Banana slices are soft, easy to chew, and less likely to cause choking compared to other options. Popcorn and hot dogs are common choking hazards for young children due to their shape and texture. While carrot sticks may be a healthy choice, they can also pose a choking risk due to their hardness and shape. Therefore, recommending banana slices to parents of toddlers is the safest choice to prevent choking incidents, making choice 'A' the correct answer. Choices 'B', 'C', and 'D' are incorrect because they can potentially cause choking in toddlers.
