Nursing Elites

1. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

2. To prevent baby bottle tooth decay, what should the nurse instruct?

• A. Water
• B. Milk
• C. Iron-fortified formula
• D. Unsweetened fruit juice

Correct answer: A

Rationale: The correct answer is A: Water. Water is the best choice to prevent baby bottle tooth decay as it does not cause tooth decay and is a good option for bedtime bottles. Milk (choice B) and iron-fortified formula (choice C) contain sugars that can contribute to tooth decay. Unsweetened fruit juice (choice D) also contains natural sugars that can be harmful to the baby's teeth.

3. What should be recommended to help prevent early childhood caries (ECC) in infants?

• A. Avoid giving the infant nighttime bottles
• B. Have the infant drink pasteurized skim milk
• C. Feed the infant iron-rich foods
• D. Give the infant fruit juice to drink

Correct answer: A

Rationale: The correct answer is 'A: Avoid giving the infant nighttime bottles' because prolonged exposure to sugars in milk during the night can lead to caries. Options 'B: Have the infant drink pasteurized skim milk' and 'D: Give the infant fruit juice to drink' are not recommended as they contain sugars that can cause cavities, especially in infants. Option 'C: Feed the infant iron-rich foods' is incorrect because while a balanced diet is important, iron-rich foods do not directly prevent caries development.

4. The PEM in which children ages 18-24 months display edema of the extremities, torso, and face, fatty liver, sparse yellow hair, and receive adequate kilocalories but not enough high-quality proteins is called?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: B

Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.

5. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.
