1. Which factor has been shown to increase the risk of development of atherosclerosis?

A. Menopause
B. Age older than 35
C. Increased levels of arachidonic acid
D. Elevated HDL cholesterol

Correct answer: A

Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.

2. What is the role of fat in digestion?

A. Digest fats in the stomach
B. Emulsify fats in the small intestine
C. Transport fats through the circulatory system
D. Split fats into smaller components

Correct answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.

3. A paranoid client refuses to eat telling you that you poisoned his food. The best intervention to this client is:

A. Taste the food in front of him and tell him that the food is not poisoned
B. Offer other types of food until the client eats
C. Simply state that the food is not poisoned
D. Offer sealed foods

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Which types of diabetes are characterized by the body's cells becoming resistant to insulin? (Select all that apply)

A. Gestational diabetes
B. Type II diabetes
C. Type I diabetes
D. Both A and B

Correct answer: D

Rationale: In both gestational diabetes and Type II diabetes, the body's cells become resistant to insulin, leading to elevated blood glucose levels. Insulin resistance in these types of diabetes prevents glucose from entering the cells, causing it to accumulate in the bloodstream. On the other hand, Type I diabetes is characterized by the body's inability to produce insulin because the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Therefore, the correct answer is both A and B. Choice C, Type I diabetes, is not characterized by insulin resistance but rather by the body's inability to produce insulin. Therefore, it is incorrect. Choice D, Both A and B, includes the correct options of gestational diabetes and Type II diabetes, making it the correct answer.

5. Each statement is true of proteins, except one. Which is the exception?

A. Proteins are composed of building blocks called amino acids
B. The classification of the 20 common amino acids is based on the properties of their side chains
C. The general structure of an amino acid varies considerably
D. Amino acids polymerize to form long chains called polypeptides

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.
