1. Based on universally-accepted color codes, what color would you expect a tank containing nitrous oxide (laughing gas) to have?

Correct answer: A

Rationale: The correct answer is A: Red. In the medical field, tanks containing nitrous oxide (laughing gas) are typically color-coded with a specific color for easy identification. Nitrous oxide tanks are commonly labeled with a red color code. This color-coding system helps healthcare providers quickly and accurately identify the contents of the tanks, reducing the risk of errors in administering gases to patients. Choices B, C, and D are incorrect because the universally-accepted color for nitrous oxide tanks is red, not blue, green, or orange.

2. In a patient with osteoporosis, which mineral is essential to prevent further bone loss?

Correct answer: D

Rationale: Calcium is crucial in preventing bone loss in patients with osteoporosis.

3. A breastfeeding mother complains that she missed her son's last two feedings and now her breasts have become full, hard, and uncomfortable. This condition is known as _____.

Correct answer: B

Rationale: Engorgement occurs when the breasts become overly full, leading to discomfort and sometimes difficulty with latching. It can be relieved by feeding or expressing milk. Mastitis, choice A, is characterized by breast inflammation usually caused by an infection. Letdown, choice C, refers to the release of milk from the breast. Galactorrhea, choice D, is the spontaneous flow of milk from the breast unassociated with childbirth or nursing.

4. Which enzyme is most essential for hydrolyzing large protein molecules?

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

5. Saturated fats are generally found in animal products with a few exceptions. Which of the following is a plant product that contains a large proportion of saturated fat?

Correct answer: D

Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.
