1. This study, which is an in-depth study of one boy, is a:
- A. case study
- B. longitudinal study
- C. cross-sectional study
- D. evaluative study
Correct answer: A
Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.
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. A nurse is teaching a parent about appropriate snack choices for her 9-month-old infant. Which of the following food choices should the nurse recommend?
- A. Skim milk
- B. Unsalted popcorn
- C. Graham crackers
- D. Raw carrots
Correct answer: C
Rationale: Graham crackers are an appropriate snack choice for a 9-month-old infant due to their texture and ease of consumption. Skim milk (Choice A) is not recommended for infants under 1 year old due to the potential risk of developing milk allergies. Unsalted popcorn (Choice B) can be a choking hazard for infants. Raw carrots (Choice D) are a potential choking hazard for a 9-month-old infant and may be difficult for them to chew and digest.
4. A common side effect of diuretic medications is _____.
- A. dry mouth
- B. urinary tract infection
- C. increased taste perception
- D. nausea

5. Which mineral-containing amino acids help to form the shape of proteins?
- A. phosphorus
- B. sulfur
- C. selenium
- D. iron
Correct answer: B
Rationale: The correct answer is B: sulfur. Sulfur-containing amino acids like cysteine and methionine play a crucial role in forming disulfide bonds within proteins. These bonds are essential for the proper folding and structural stability of proteins. Phosphorus (choice A), selenium (choice C), and iron (choice D) do not directly contribute to shaping proteins through bond formation.
