In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the __________.

  • A. way the angry encounters end
  • B. amount of unresolved anger
  • C. frequency of angry encounters
  • D. children's emotional reactions
Correct Answer: D

Rationale: In an experimental study examining whether the way angry encounters end affects children's emotional reactions, the dependent variable would be the children's emotional reactions. The dependent variable is the outcome being measured or tested in an experiment. In this study, the researchers are trying to understand how the way angry encounters end influences children's emotions. Therefore, the emotional reactions of the children would be the dependent variable that is being studied and measured in relation to the way angry encounters end. Choices A, B, and C are not the dependent variable in this scenario. While they may be related factors, the main focus of the study is on how the way angry encounters end impacts children's emotional reactions, making children's emotional reactions the dependent variable.

In developing countries, the most readily available intervention for promoting the recovery of preterm babies is _________.

  • A. hospitalization
  • B. care in an isolette
  • C. lying on a waterbed
  • D. skin-to-skin 'kangaroo care'
Correct Answer: D

Rationale: In developing countries, the most readily available intervention for promoting the recovery of preterm babies is skin-to-skin 'kangaroo care.' This involves direct skin-to-skin contact between the baby and a caregiver, typically the mother, which helps regulate the baby's body temperature, improve bonding, and support overall development. Kangaroo care can be easily implemented even in resource-limited settings and has been shown to have positive effects on preterm infants' health outcomes. Choices A, B, and C are incorrect because hospitalization, care in an isolette, and lying on a waterbed are not specifically tailored interventions that address the unique needs of preterm babies in developing countries like kangaroo care does.

Men with even tiny amounts of dioxin in their bloodstream father __________.

  • A. nearly twice as many girls as boys
  • B. nearly three times as many boys as girls
  • C. more twins and triplets than unaffected men
  • D. fewer children than unaffected men
Correct Answer: A

Rationale: Men with even tiny amounts of dioxin in their bloodstream father nearly twice as many girls as boys. This is due to the impact of dioxin exposure on sperm cells, leading to a skewed ratio of female to male offspring. Choice B is incorrect as the question specifically mentions that men father more girls than boys. Choice C is incorrect as dioxin exposure does not necessarily lead to more twins and triplets. Choice D is incorrect as men with dioxin in their bloodstream father more girls, not fewer children overall.

Mounting evidence suggests that __________ is a major contributor to SIDS.

  • A. impaired brain functioning
  • B. higher-than-average birth weight
  • C. organized and patterned sleep behavior
  • D. a family history of chromosomal abnormalities
Correct Answer: A

Rationale: Impaired brain functioning is a major contributor to Sudden Infant Death Syndrome (SIDS). Research has shown that abnormalities in the brainstem, which controls automatic functions like breathing and heart rate, can play a role in SIDS cases. As such, mounting evidence suggests that compromised brain functioning is a significant factor in the occurrence of SIDS. Choices B, C, and D are incorrect. Higher-than-average birth weight, organized and patterned sleep behavior, and a family history of chromosomal abnormalities are not identified as major contributors to SIDS according to the provided information.

Currently, the most widely used potent teratogen is __________.

  • A. aspirin
  • B. diethylstilbestrol (DES)
  • C. thalidomide
  • D. isotretinoin
Correct Answer: D

Rationale: The correct answer is D, isotretinoin. Isotretinoin is a medication commonly used to treat severe acne, but it is a potent teratogen, meaning it can cause severe birth defects if taken during pregnancy. Aspirin (choice A) is not a widely used potent teratogen. Diethylstilbestrol (DES) (choice B) was a known teratogen, but it is not currently widely used. Thalidomide (choice C) was another historical teratogen, but it is also not currently widely used. Therefore, isotretinoin is the most relevant answer as it is a commonly used medication that poses a high risk of birth defects if used during pregnancy.

A combined Apgar score of __________ indicates that the infant is in good physical condition.

  • A. less than 3
  • B. 3 or 4
  • C. 5 or 6
  • D. 7 or better
Correct Answer: D

Rationale: A combined Apgar score of 7 or better indicates that the infant is in good physical condition. The Apgar score is a quick assessment of a newborn's overall health shortly after birth. It evaluates the baby's heart rate, respiratory effort, muscle tone, reflexes, and color. A score of 7 or higher indicates that the baby is adjusting well to life outside the womb. Choices A, B, and C are incorrect as they represent scores that indicate the infant may need medical attention or assistance as they are below the threshold of 7 which signifies good physical condition.
