1. What does preload refer to?

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

2. A patient has been told to monitor her LH levels. Which of the following potential conditions might the patient be suffering from?

Correct answer: D

Rationale: Luteinizing hormone (LH) is released by the pituitary gland to stimulate ovulation. One of the common reasons for monitoring LH levels is infertility. In women with infertility, LH levels are monitored to time intercourse accurately to maximize the chances of conception. Menorrhagia (choice A) is characterized by heavy menstrual bleeding and is not directly related to LH levels. Grave's Disease (choice B) is an autoimmune disorder affecting the thyroid gland and is not typically monitored by LH levels. Menopause (choice C) is a natural process marking the end of a woman's reproductive years and is not a condition where LH monitoring for infertility is common.

3. What does an individual who believes in the magicoreligious theory of illness and disease think is the cause of illness?

Correct answer: B

Rationale: Individuals who adhere to the magicoreligious theory of illness and disease attribute the cause of illness to supernatural forces. In this perspective, the world is perceived as governed by supernatural forces that influence the well-being of individuals. The belief is that these forces can bring about both good and evil outcomes. Choices A, C, and D are incorrect. Germs and viruses are associated with the biomedical theory of illness. Eating imbalanced hot or cold foods is linked to the yin/yang naturalist theory. Imbalance within one's spiritual nature is not a recognized cause of illness in any of the established theories of illness.

4. Many Asians believe in the yin/yang theory, which is rooted in the ancient Chinese philosophy of Tao. Which statement most accurately reflects this philosophy's view of "health"??

Correct answer: C

Rationale: In the yin/yang theory rooted in ancient Chinese philosophy, health is believed to exist when all aspects of a person are in perfect balance. This includes physical, mental, emotional, and spiritual well-being. Choice C accurately reflects this philosophy's view of health. Choices A, B, and D do not capture the essence of the yin/yang theory. Being able to work and produce, being happy and stable, or caring for others and functioning socially, while important, do not encompass the holistic balance emphasized in the yin/yang theory.

5. A client is diagnosed with ariboflavinosis. Which of the following foods should the nurse serve this client?

Correct answer: B

Rationale: Ariboflavinosis is a vitamin B-2 deficiency. Symptoms may include cracks around the mouth, inflammation of the tongue, or light sensitivity. Foods rich in vitamin B-2, like milk, liver, green vegetables, or whole grains, are recommended. Citrus fruits (choice A) are good sources of vitamin C, not B-2. Fish (choice C) is a source of protein and omega-3 fatty acids but not a significant source of vitamin B-2. Potatoes (choice D) are a source of carbohydrates but do not provide high levels of vitamin B-2.
