1. Why are neonates predisposed to problems with thermoregulation?
- A. Renal function is not fully developed.
- B. Flexed posture favors heat loss.
- C. A large body surface area favors heat loss to the environment.
- D. A thick layer of subcutaneous fat provides excellent insulation.
Correct answer: C
Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.
2. In females, the twenty-third pair of chromosomes is labeled as __________.
- A. an autosome
- B. dizygotic
- C. XX
- D. XY
Correct answer: C
Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
3. Classical and operant conditioning theories are classified under _________________, while sociocultural theory and Piaget's theory fall under ________________.?
- A. Psychodynamic; cognitive
- B. Learning; behavior modelling
- C. Behavioral; sociocultural
- D. Centration; cognitive
Correct answer: A
Rationale: Classical and operant conditioning theories are forms of learning theories, making them fall under the category of cognitive theories. On the other hand, sociocultural theory and Piaget's theory are cognitive theories that focus on how individuals perceive and process information, hence correctly classified under cognitive theories. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not accurately represent the classifications of the specified theories.
4. Terrance, whose birth mother drank heavily throughout pregnancy, has a thin upper lip, short eyelid openings, a small head, and a smooth philtrum. His physical growth has been slow, and he shows impairment in memory, attention span, motor coordination, and social skills. Terrance has __________.
- A. fetal alcohol syndrome
- B. partial fetal alcohol syndrome
- C. alcohol-related neurodevelopmental disorder
- D. cytomegalovirus
Correct answer: A
Rationale: Terrance exhibits a combination of physical abnormalities like a thin upper lip, short eyelid openings, a small head, and a smooth philtrum, along with developmental delays and cognitive impairments. These characteristics are indicative of fetal alcohol syndrome (FAS), which is caused by maternal alcohol consumption during pregnancy. FAS is a severe condition resulting from prenatal alcohol exposure and is characterized by a range of physical, cognitive, and behavioral issues. Choice A, fetal alcohol syndrome, is the correct answer as it aligns with Terrance's symptoms and the effects of maternal alcohol consumption during pregnancy. Choices B, C, and D are incorrect because they do not encompass the full spectrum of symptoms and impairments presented by Terrance, which are specific to fetal alcohol syndrome.
5. A client is experiencing a seizure. Which of the following interventions should the nurse implement?
- A. Place a tongue depressor in the client's mouth
- B. Loosen tight clothing around the client
- C. Restrain the client's arms and legs
- D. Administer 100% oxygen via non-rebreather mask
Correct answer: B
Rationale: During a seizure, it is essential to loosen tight clothing around the client to prevent injury and promote adequate ventilation. Placing any objects, like a tongue depressor, in the client's mouth can lead to airway obstruction or injury. Restraining the client's arms and legs can exacerbate the situation by increasing muscle rigidity and potentially causing injury. Administering oxygen via a non-rebreather mask is not typically indicated during a seizure unless respiratory distress is present.
