1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

2. A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?

Correct answer: D

Rationale: If the infant turns away after taking most of the feeding, it indicates they are full, and continuing to feed may lead to overfeeding. Choice A is incorrect because it is not safe to use formula that remains in the bottle for another feeding due to the risk of bacterial contamination. Choice B is incorrect as whole milk should be introduced after the infant is 12 months old, not 9 months old. Choice C is incorrect as diluting formula can compromise the infant's nutrition and should not be done without healthcare provider guidance.

3. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

4. What is the most common type of kidney stone?

Correct answer: B

Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.

5. What is a likely effect on a patient whose lab results reveal hypoalbuminemia?

Correct answer: D

Rationale: Hypoalbuminemia, which refers to low albumin levels in the blood, is often associated with edema. Albumin helps maintain oncotic pressure, which keeps fluid within blood vessels. When albumin levels are low, this pressure decreases, leading to fluid leakage from the blood vessels into the surrounding tissues, resulting in edema. The other choices are less likely effects of hypoalbuminemia. Hypoalbuminemia doesn't directly cause infections (Choice A), rickets (Choice B) caused by vitamin D deficiency, or hypertension (Choice C) associated with factors like high sodium intake, obesity, and genetic predisposition.
