1. How many words does a typical 12-month-old infant use?
- A. About 12 words
- B. Twenty or more words
- C. About 50 words
- D. Two, plus 'mama' and 'papa'
Correct answer: D
Rationale: A typical 12-month-old infant typically uses very few words, with 'mama' and 'papa' being common early words. At this age, most infants are still in the early stages of language development, and their vocabulary is limited. Choices A, B, and C suggest higher word counts which are not typical for infants at this age.
2. In order to establish and maintain successful breastfeeding, which practice should a lactating mother try to follow?
- A. Initiate breastfeeding within 24 hours of birth
- B. Breastfeed on a schedule of every 2 to 3 hours
- C. Give a pacifier to an infant between feedings
- D. Find a breastfeeding support group to troubleshoot problems
Correct answer: D
Rationale: The correct answer is D. Finding a breastfeeding support group is crucial for a lactating mother to establish and maintain successful breastfeeding. This group can offer valuable advice, tips, and encouragement, helping the mother troubleshoot any issues that may arise during breastfeeding. Choices A, B, and C are incorrect because breastfeeding is a natural process that should not be overly scheduled, and giving a pacifier between feedings can interfere with establishing proper breastfeeding techniques.
3. Which of the following nutrients does not provide energy?
- A. Proteins
- B. Carbohydrates
- C. Fats
- D. Vitamins
Correct answer: D: Vitamins
Rationale: Proteins, carbohydrates, and fats are macronutrients that provide energy in the form of calories when consumed and metabolized by the body. Each gram of protein or carbohydrate provides about 4 calories, and each gram of fat provides about 9 calories. On the other hand, vitamins do not provide energy or calories. They are micronutrients that are essential for various biochemical and physiological processes in the body, including the metabolism of macronutrients. However, they do not contribute directly to the energy supply. Therefore, the correct answer is 'D: Vitamins'. Choices A, B, and C (Proteins, Carbohydrates, and Fats) are incorrect because they are macronutrients that do provide energy/calories when metabolized.
4. Myxedema coma is a life-threatening complication of long-standing and untreated hypothyroidism with one of the following characteristics.
- A. Hyperglycemia
- B. Hypothermia
- C. Hyperthermia
- D. Hypoglycemia
Correct answer: A
Rationale: Myxedema coma is associated with hypothermia, not hyperthermia. Therefore, the correct characteristic of myxedema coma is hypothermia. This condition is a medical emergency that requires prompt recognition and intervention to prevent serious complications. The presence of hyperglycemia is not a defining characteristic of myxedema coma, making choice A the correct answer in this case. Hyperthermia and hypoglycemia are not typically seen in myxedema coma and are not consistent with the clinical presentation of this condition.
5. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?
- A. Hypodipsia
- B. Hypernatremia
- C. Hypokalemia
- D. Osmosis
Correct answer: D
Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.
