What is the conversion of genetic information in RNA into a sequence of amino acids?

Correct Answer: A

Rationale: The correct answer is 'translation.' Translation is the process where the genetic information in messenger RNA (mRNA) is decoded to produce a specific sequence of amino acids, forming a protein. This process occurs at ribosomes within the cell. Option B, 'transcription,' is incorrect as transcription is the process of synthesizing mRNA from a DNA template. Options C and D are irrelevant as they are not related to the conversion of genetic information into amino acids.

Correct Answer: B

Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.

Correct Answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

Correct Answer: B

Rationale: The correct answer is B: eyes, nerves, and kidneys. In diabetes, major complications result from damage to small blood vessels that supply these organs. Damage to the eyes can lead to retinopathy, to the nerves causing neuropathy, and to the kidneys causing nephropathy. Choices A, C, and D are incorrect as they do not represent the typical major complications associated with diabetes.

Correct Answer: D

Rationale: The corrected question emphasizes that patients with eating disorders like bulimia should not brush immediately after vomiting as it can worsen enamel erosion due to the acidic content in the mouth. The correct answer is D because patients should rinse with water or a fluoride mouthwash instead of brushing to protect their teeth. Choice A is incorrect because encouraging patients to brush after vomiting is not recommended. Choice B is incorrect as the reason provided is valid but not suitable for the action of encouraging brushing. Choice C is incorrect as the reason for not brushing after vomiting is to prevent enamel erosion.

Correct Answer: D

Rationale: Confusion is the most likely symptom associated with late dumping syndrome. Late dumping syndrome occurs when blood sugar levels drop rapidly after eating due to rapid gastric emptying. While abdominal cramps, nausea, and diarrhea can occur with dumping syndrome, confusion is specifically linked to late dumping syndrome due to hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: Carbohydrates. Carbohydrates, especially fermentable sugars, are the most significant dietary factor in the development of dental caries. When these sugars are consumed, they can be fermented by bacteria in the mouth, leading to the production of acids. These acids lower the pH in the mouth, creating an acidic environment that promotes demineralization of the tooth enamel, ultimately causing dental caries. Choices B, C, and D are incorrect because while vitamins and minerals are important for overall health, they do not have the same direct impact on the development of dental caries as fermentable carbohydrates do. Fats, on the other hand, do not play a significant role in the development of dental caries.

Correct Answer: B

Rationale: Muscle weakness is a common sign of vitamin D deficiency. Vitamin D is essential for calcium absorption and bone health, and its deficiency can lead to muscle weakness. Brittle nails (Choice A) are not typically associated with vitamin D deficiency. Night blindness (Choice C) is related to vitamin A deficiency, not vitamin D deficiency. Hair loss (Choice D) can be linked to various factors, but it is not a common sign of vitamin D deficiency.

Correct Answer: A

Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.
