1. Sickle cell disease is an example of an inherited mistake in the amino acid sequence.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.

2. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

• A. Avoiding all foods that contain cholesterol
• B. Reducing sodium intake to less than 2 g/day
• C. Limiting total fat intake to less than 30% of energy intake
• D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.

3. Which of the following groups of vitamins are fat-soluble?

• A. vitamins B and C
• B. vitamins A and C
• C. vitamins B, E, K, D
• D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.

4. A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses?

• A. Phosphorus
• B. Calcium
• C. Chloride
• D. Zinc

Correct answer: B

Rationale: Corrected Question: A nurse is preparing to teach a group of clients about vitamins and minerals. The nurse should include in the teaching that which of the following minerals is necessary for the transmission of nerve impulses? Correct Answer: Calcium Rationale: Calcium is crucial for nerve transmission, muscle contraction, and blood clotting. It plays a vital role in the proper functioning of the nervous system. Phosphorus is important for bone health and energy metabolism, not nerve impulse transmission. Chloride is an electrolyte important for fluid balance but not directly involved in nerve impulse transmission. Zinc is essential for immune function and wound healing but not specifically required for nerve impulse transmission.

5. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:

• A. tip of the nose to the base of the neck
• B. the distance from the tip of the nose to the middle of the neck
• C. the distance from the tip of the nose to the tip of the ear lobe
• D. eight to ten inches

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
