Which outcome has been shown to be most closely associated with breastfeeding infants of mothers who smoke?

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.

Correct Answer: B

Rationale: Metabolic control is crucial for women with gestational diabetes to prevent the development of macrosomia, which is characterized by an abnormally large baby. This condition poses risks such as birth injuries and necessitates careful management of blood sugar levels. Microsomia is not a known term related to this context. Type 1 and type 2 diabetes are not conditions the infant would develop as a result of gestational diabetes in the mother.

Correct Answer: D

Rationale: The correct answer is 'D: infectious diarrhea.' Research has extensively explored the use of probiotics in the prevention and treatment of infectious diarrhea. Probiotics can aid in restoring the balance of gut flora, thereby reducing symptoms. Choices A, B, and C are incorrect because while probiotics may have some benefits for these conditions, the primary focus of research in relation to probiotics and intestinal illness has been on infectious diarrhea.

Correct Answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

Correct Answer: A

Rationale: High blood pressure, or hypertension, is typically defined as having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Therefore, the correct answer is A. Choice B is incorrect because it suggests a higher systolic measurement than the standard definition. Choice C is incorrect as it provides an even higher systolic measurement and a much higher diastolic measurement. Choice D is also incorrect as it suggests extremely elevated blood pressure values, well above the typical definition of hypertension.

Correct Answer: B

Rationale: A condition that is conducive to the development of dental caries is described as cariogenic. Cariogenic refers to foods or conditions that promote the development of dental caries by providing an environment for bacteria to thrive and produce acids that erode tooth enamel. Choice A, periodontal, is incorrect as it relates to the supporting structures of the teeth rather than the development of dental caries. Choice C, gingival, is also incorrect as it pertains to the gums rather than the causation of dental caries. Choice D, bacteriophilic, is not the term commonly used to describe conditions that lead to dental caries, making it an incorrect choice.

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.

Correct Answer: C

Rationale: Corrected Rationale: Protein provides 4 kcal per gram, making it a good source of energy to increase caloric intake. While fiber and water are important for other aspects of health, they do not provide energy like protein does. Vitamins are essential for various bodily functions but do not contribute directly to caloric intake.

Correct Answer: D

Rationale: The correct answer is 'enriched flour.' In ingredient lists, items are typically listed by weight in descending order. Therefore, the first ingredient, in this case, 'enriched flour,' is the most abundant by weight. Choice A, 'milk,' is not the most abundant as it appears last in the list. Choice B, 'eggs,' and choice C, 'sugar,' also rank lower in the list compared to 'enriched flour,' making them less abundant by weight.
