1. How many amino acids are essential?
- A. 5
- B. 7
- C. 9
- D. 13
Correct answer: C
Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.
2. A client is being taught about following a low-cholesterol diet after coronary artery bypass grafting. Which of the following food choices reflects the client's understanding of these dietary instructions?
- A. Liver
- B. Milk
- C. BEANS
- D. Eggs
Correct answer: C
Rationale: Choosing beans as a food option indicates that the client understands the low-cholesterol diet instructions. Beans are a good source of fiber and plant-based protein, which can help lower cholesterol levels. On the other hand, liver and eggs are high in cholesterol and should be limited in a low-cholesterol diet. Milk, especially whole milk, can also be high in saturated fats and cholesterol, so it is not the best choice for a low-cholesterol diet.
3. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?
- A. Natural active immunity
- B. Natural passive immunity
- C. Artificial active immunity
- D. Artificial passive immunity
Correct answer: B
Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.
4. What is the most common type of kidney stone?
- A. Cystine
- B. Calcium
- C. Struvite
- D. Uric acid
Correct answer: B
Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.
5. Which symptoms are associated with cancer of the colon?
- A. constipation, ascites, and mucus in the stool
- B. diarrhea, heartburn, and eructation
- C. blood in the stools, anemia, and 'pencil-shaped' stools
- D. anorexia, hematemesis, and increased peristalsis
Correct answer: C
Rationale: The correct symptoms associated with cancer of the colon are blood in the stools, anemia, and 'pencil-shaped' stools. These symptoms are classic indicators of colorectal cancer. Choices A, B, and D do not typically present in colorectal cancer. Constipation, ascites, and mucus in the stool are more commonly associated with other gastrointestinal conditions. Diarrhea, heartburn, and eructation are not typical symptoms of colon cancer. Anorexia, hematemesis, and increased peristalsis are more indicative of other gastrointestinal issues and not specific to colon cancer.
