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. Beta-adrenergic agonists such as Salbutamol are given to Reggie, a child with asthma. Such drugs are administered primarily to do which of the following?

• A. Dilate the bronchioles
• B. Reduce secondary infections
• C. Decrease postnasal drip
• D. Reduce airway inflammation

Correct answer: A

Rationale: Beta-adrenergic agonists like Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

3. A new parent reports to the nurse that the baby looks cross-eyed several times a day. The nurse teaches the parents that this finding should resolve in how long?

• A. 2 months
• B. 2 weeks
• C. 1 year
• D. 4 months

Correct answer: D

Rationale: Transient strabismus, causing the baby to look cross-eyed, is due to poor neuromuscular control of the eye muscles. This condition typically resolves on its own within 3 to 4 months as the infant's neuromuscular control improves. Parents should be reassured that this is a common and temporary issue in infants. Choice A is incorrect as it is too long for the resolution of transient strabismus. Choice B is incorrect as 2 weeks is too short for resolution. Choice C is incorrect as 1 year is too long for transient strabismus to resolve.

4. Which of the following statements regarding 2-rescuer child CPR is correct?

• A. The chest should be compressed with one hand, and a compression-to-ventilation ratio of 30:2 should be used.
• B. The chest should not be allowed to fully recoil in between compressions.
• C. A compression-to-ventilation ratio of 15:2 should be used if an advanced airway is in place.
• D. Compress the chest with one or two hands to a depth equal to one-third the diameter of the chest.

Correct answer: D

Rationale: During 2-rescuer child CPR, it is important to compress the chest with one or two hands to a depth equal to one-third the diameter of the chest. This technique ensures effective chest compressions are being delivered to help circulate blood and oxygenate the child's body. Choice A is incorrect because both hands should be used for chest compressions in 2-rescuer CPR. Choice B is incorrect as allowing the chest to fully recoil between compressions is essential to create negative pressure and facilitate blood flow back to the heart. Choice C is incorrect as the standard compression-to-ventilation ratio for child CPR is 30:2, regardless of whether an advanced airway is in place.

5. What is the most appropriate action to prevent heat loss in a newborn immediately after birth?

• A. Place the newborn in an incubator
• B. Bathe the newborn right away
• C. Dry the newborn thoroughly
• D. Feed the newborn

Correct answer: C

Rationale: Drying the newborn thoroughly is the most appropriate action to prevent heat loss immediately after birth. This helps to prevent heat loss through evaporation, which is crucial in maintaining the newborn's body temperature. Placing the newborn in an incubator can be a secondary step after ensuring the baby is dry. Bathing the newborn right away is not recommended as it can lead to further heat loss through evaporation. Feeding the newborn is important but not an immediate action to prevent heat loss; ensuring the baby is dry and warm takes precedence.
