1. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.

2. Why are blood glucose levels high in type 1 diabetes?

• A. The urinary excretion of glucose is impaired
• B. The lean body mass is metabolized to produce glucose via gluconeogenesis
• C. The absorption of glucose from the gastrointestinal tract is more efficient
• D. There is insufficient insulin to facilitate the transport of glucose into the cells

Correct answer: D

Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.

3. Which nutrient deficiency produces microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia?

• A. Zinc
• B. Iron
• C. Sodium
• D. Potassium

Correct answer: B

Rationale: A deficiency in iron can lead to various symptoms, such as microcytic anemia, fatigue, faulty digestion, blue sclerae, pale conjunctivae, and tachycardia. Iron-deficiency anemia may be caused by inadequate dietary intake; accelerated demand or losses; and inadequate absorption secondary to diarrhea, decreased acid secretions, or antacid therapy. Iron deficiency is frequently the result of postnatal feeding practices and has a serious impact on growth and mental and psychomotor development in infants and children. Choices A, C, and D are incorrect as zinc deficiency typically presents with symptoms like impaired wound healing, taste abnormalities, and hair loss; sodium deficiency can lead to symptoms such as muscle cramps, dizziness, and confusion; and potassium deficiency may cause muscle weakness, fatigue, and abnormal heart rhythms.

4. A client is being prepared for placement of a catheter for total parenteral nutrition. Which of the following access sites should be planned for catheter insertion?

• A. Left antecubital vein
• B. Right subclavian vein
• C. Right femoral artery
• D. Left arm radial artery

Correct answer: B

Rationale: The correct answer is the Right subclavian vein. When preparing a client for placement of a catheter for total parenteral nutrition, the preferred access site for catheter insertion is the subclavian vein due to its large size, central location, and lower risk of infection compared to peripheral veins. The other options provided (Left antecubital vein, Right femoral artery, and Left arm radial artery) are not suitable access sites for central venous catheter insertion for total parenteral nutrition.

5. What gastrointestinal side effects are associated with antisecretory drugs such as proton pump inhibitors?

• A. Nausea and vomiting
• B. Gastroparesis
• C. Dumping syndrome
• D. Flatulence

Correct answer: A

Rationale: Proton pump inhibitors (PPIs) are a type of antisecretory drug that can cause nausea and vomiting by altering stomach acid production. These are common side effects associated with PPIs. Gastroparesis (B) is a condition that affects the stomach muscles and prevents proper stomach emptying; it is not a side effect of PPIs. Dumping syndrome (C) is a group of symptoms that can occur after having part of your stomach removed and is not a side effect of PPIs. While some people might experience flatulence (D) when taking PPIs, it is not as commonly associated with these drugs as the effects of nausea and vomiting.
