Human Growth and Development Exam Questions
1. In ecological systems theory, how does Toby's move just before entering fourth grade represent a significant change in his life?
- A. Microsystem
- B. Mesosystem
- C. Exosystem
- D. Chronosystem
Correct answer: D
Rationale: In ecological systems theory, the chronosystem refers to the dimension of time and how events and transitions over time can influence an individual's development. Toby's move just before entering fourth grade represents a significant change in his life that falls under the chronosystem. The microsystem involves the immediate environments and relationships that directly influence an individual, the mesosystem relates to connections between these environments, and the exosystem includes external settings that indirectly influence the individual, such as parents' workplaces. Therefore, Toby's move best exemplifies a change in the chronosystem due to the temporal influence on his development.
2. Which of the following is not true about Pure Experimental research?
- A. There is a control group
- B. There is an experimental group
- C. Selection of subjects in the control group is randomized
- D. There is a careful selection of subjects in the experimental group
Correct answer: D
Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.
3. What is the appropriate site to administer an intramuscular (IM) vaccine to a newborn?
- A. The dorsal gluteal muscle
- B. The vastus lateralis muscle
- C. The ventral gluteal muscle
- D. The biceps muscle
Correct answer: B
Rationale: The correct site to administer an intramuscular (IM) vaccine to a newborn is the vastus lateralis muscle. For newborns, the vastus lateralis is preferred over the dorsogluteal site because the dorsogluteal site has been associated with low antibody seroconversion rates, indicating a reduced immune response. The vastus lateralis is also recommended for IM injections in newborns, while the deltoid muscle is preferred for older infants and children. The ventral gluteal muscle and the biceps muscle are not appropriate sites for IM injections. Therefore, choice B is the correct answer.
4. What primarily determines the Dietary Reference Intake (DRI) for protein?
- A. Intake of fatty acids
- B. Gender
- C. Height
- D. Body weight
Correct answer: D
Rationale: The Dietary Reference Intake (DRI) for protein is primarily determined by an individual's body weight. This is because the body's protein requirement is proportionate to its size, which is generally reflected in the body weight. Therefore, choice D is correct. Choices A, B, and C are incorrect: While factors such as fatty acid intake, gender, and height can influence an individual's overall nutritional needs, they do not directly determine the DRI for protein.
5. At what age may an infant close their eyes to bright lights and show improved head control?
- A. 30-33 weeks after conception
- B. 34-36 weeks after conception
- C. Less than 30 weeks after conception
- D. 37-40 weeks after conception
Correct answer: A
Rationale: Around 30-33 weeks after conception, infants usually start closing their eyes in response to bright lights and exhibit enhanced head control. This developmental milestone indicates progress in their visual and motor abilities, reflecting the maturation of their neurological system. As preterm infants continue to grow and develop, they gradually acquire these skills, showcasing the natural progression of their sensory and motor functions.
