1. A vegan patient might be at risk for deficiency in which of the following nutrients?
- A. Vitamin B12
- B. Vitamin C
- C. Carbohydrates
- D. Fiber
Correct answer: A
Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.
2. Which outcome has been shown to be most closely associated with breastfeeding infants of mothers who smoke?
- A. poor temperature regulation
- B. vision impairment
- C. vomiting
- D. elevated blood pressure
Correct answer: C
Rationale: The correct answer is C: vomiting. Infants breastfed by mothers who smoke are more likely to experience vomiting and gastrointestinal issues due to the transfer of nicotine and other harmful substances through breast milk. Choices A, B, and D are incorrect. Poor temperature regulation, vision impairment, and elevated blood pressure are not the primary outcomes closely associated with breastfeeding infants of mothers who smoke.
3. Muscle weakness due to wasting would most likely be evaluated by which test?
- A. recall of food intake
- B. skinfold thickness
- C. handgrip strength
- D. red blood cell levels
Correct answer: C
Rationale: Handgrip strength is a reliable test to assess muscle function and detect muscle weakness due to wasting. It is often used to identify conditions like sarcopenia in clinical settings. Options A, B, and D are not suitable for evaluating muscle weakness. Food intake recall does not directly measure muscle function, skinfold thickness assesses body fat but not muscle strength, and red blood cell levels are unrelated to muscle wasting.
4. AIDS enteropathy is most commonly manifested as _____.
- A. abdominal pain and rectal bleeding
- B. diarrhea and weight loss
- C. abdominal bloating and flatulence
- D. rectal fissures and constipation
Correct answer: B
Rationale: AIDS enteropathy typically presents as diarrhea and weight loss due to the impact of HIV on the gastrointestinal tract. While abdominal pain and rectal bleeding (Choice A), abdominal bloating and flatulence (Choice C), and rectal fissures and constipation (Choice D) can occur in some cases, the most common manifestations are diarrhea and weight loss.
5. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
