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. In order to establish and maintain successful breastfeeding, which practice should a lactating mother try to follow?

A. Initiate breastfeeding within 24 hours of birth
B. Breastfeed on a schedule of every 2 to 3 hours
C. Give a pacifier to an infant between feedings
D. Find a breastfeeding support group to troubleshoot problems

Correct answer: D

Rationale: The correct answer is D. Finding a breastfeeding support group is crucial for a lactating mother to establish and maintain successful breastfeeding. This group can offer valuable advice, tips, and encouragement, helping the mother troubleshoot any issues that may arise during breastfeeding. Choices A, B, and C are incorrect because breastfeeding is a natural process that should not be overly scheduled, and giving a pacifier between feedings can interfere with establishing proper breastfeeding techniques.

5. The principal cation in plasma and interstitial fluid is:

A. Sodium
B. Potassium
C. Calcium
D. Magnesium

Correct answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.
