Fat-soluble vitamins are absorbed in the body most efficiently when consumed with:
Water
Dietary fat
Fiber

A patient presents with frequent nosebleeds and slow wound healing. After reviewing their diet, you suspect a deficiency in a fat-soluble vitamin. Which vitamin is most likely deficient, and what evidence supports your reasoning?
Vitamin A, because it is essential for vision
Vitamin D, because it aids calcium absorption
Vitamin E, because it acts as an antioxidant
Vitamin K, because it is necessary for blood clotting
Given a patient who follows a strict vegan diet and has limited sun exposure, which fat-soluble vitamin deficiency are they most at risk for, and why?
Vitamin A, because it is only found in animal products
Vitamin D, because plant-based diets and lack of sunlight reduce its synthesis and intake
Vitamin E, because it is not present in plant foods
Vitamin K, because it is not synthesized in the body
A person consumes a diet very low in fat. After several months, they begin to show symptoms of multiple vitamin deficiencies. Explain how their dietary pattern could lead to deficiencies in fat-soluble vitamins.
Fat is required for the absorption of fat-soluble vitamins, so a low-fat diet impairs their absorption.
Fat increases the metabolism of vitamins, so less fat means more vitamins are used.
Fat is converted directly into vitamins in the body.
Fat blocks the absorption of water-soluble vitamins.
A patient is experiencing muscle weakness and neurological problems. Laboratory tests reveal increased oxidative damage to their cells. Which fat-soluble vitamin deficiency is most likely responsible, and what is the underlying mechanism?
Vitamin A, due to its role in vision
Vitamin D, due to its role in bone health
Vitamin E, due to its antioxidant protection of cell membranes
Vitamin K, due to its role in blood clotting
