1. Which statement best describes direct contact as a mode of pathogen transmission?

• A. Transmission through large aerosols produced by sneezing or coughing
• B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
• C. Transmission of infectious agents carried by dust
• D. Transmission through skin-to-skin contact or body fluids

Correct answer: D

Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.

2. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

3. When is a newborn considered premature?

• A. Weighs less than 6.5 pounds.
• B. Is born to a heroin-addicted mother.
• C. Is born before 37 weeks gestation.
• D. Has meconium in or around its mouth.

Correct answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

4. Which of the following statements regarding SIDS is correct?

• A. SIDS can occur in premature infants.
• B. It is most commonly a result of child abuse.
• C. Death usually occurs during sleep.
• D. SIDS can be prevented by placing the baby on its back to sleep.

Correct answer: C

Rationale: The correct statement regarding SIDS is that death usually occurs during sleep. Sudden Infant Death Syndrome (SIDS) is the unexpected death of a seemingly healthy infant, typically occurring during sleep. The exact cause of SIDS is not fully understood. While placing the baby on its back to sleep is a recommended preventive measure to reduce the risk of SIDS, it cannot guarantee prevention. Choice A is incorrect as SIDS is not limited to premature infants. Choice B is incorrect as SIDS is not primarily caused by child abuse.

5. What is the MOST common cause of shock in infants and children?

• A. Severe allergic reaction
• B. Dehydration
• C. Accidental poisoning
• D. Cardiac failure

Correct answer: B

Rationale: Dehydration is the most common cause of shock in infants and children. In children, the body's fluid reserves are smaller compared to adults, making them more susceptible to dehydration, which can lead to shock if not promptly addressed. Severe allergic reactions, accidental poisoning, and cardiac failure can also cause shock, but dehydration is the most frequent cause in this age group.
