When ventilating an apneic 3-year-old child with a bag-valve mask device, what is the MOST important action to take?

Correct Answer: A

Rationale: When ventilating an apneic child, the most important action is to avoid hyperventilation and ensure adequate chest rise. Hyperventilation can lead to decreased cardiac output and increased intracranial pressure. Adequate chest rise confirms effective ventilation and minimizes the risk of complications. Choice B is incorrect because using both hands to squeeze the bag may not ensure proper ventilation and can lead to complications. Choice C is incorrect as inserting an oropharyngeal airway is not the initial action in ventilating an apneic child with a bag-valve mask. Choice D is incorrect as providing ventilations every 3 to 5 seconds may not be appropriate for effective ventilation in a pediatric patient.

Correct Answer: D

Rationale: Bruising to the upper back is more suspicious for child abuse compared to the other listed injuries. In young children, injuries like bruises to the upper back are less likely to be accidental and may raise concerns about physical abuse. The upper back is an area less prone to accidental injuries during play or falls. Multiple bruises to the shins are common in active children. A burned hand with splash marks may suggest accidental burns. A small laceration to the chin is also a common injury from falls in children. Therefore, the bruising on the upper back is more concerning for possible child abuse.

Correct Answer: B

Rationale: In obstetrics, gravida indicates the number of pregnancies, including the current one. Para indicates the number of pregnancies carried to viability (20 weeks or more). Since the patient has been pregnant twice but only carried one pregnancy past 20 weeks, her obstetric history should be documented as gravida 2, para 0. The miscarriage at 19 weeks does not contribute to the para count. Choice A (gravida 2, para 1) would indicate that she has had two pregnancies with one resulting in a live birth, which is incorrect. Choice C (gravida 1, para 1) would indicate that she has had one pregnancy with one live birth, which does not reflect her obstetric history. Choice D (gravida 0, para 2) would indicate that she has never been pregnant past 20 weeks, which is also inaccurate.

Correct Answer: C

Rationale: Braxton-Hicks contractions are irregular and usually do not increase in intensity. Unlike true labor contractions, they tend to alleviate with a change in position, making option C the correct choice. Choices A, B, and D are incorrect because Braxton-Hicks contractions do not follow rupture of the amniotic sac, are not intensified by activity or accompanied by a pink discharge, and do not consistently become stronger or are not alleviated by changing position.

Correct Answer: D

Rationale: When encountering a protruding limb during delivery, it is crucial to recognize this as an emergency situation. The correct action is to cover the limb with a sterile towel to prevent injury and transport the mother immediately to a medical facility. Attempting to push the limb back into the vagina or trying to manipulate the baby's position can be harmful and delay necessary medical intervention. Encouraging the mother to push and providing high-flow oxygen is not appropriate in this scenario as immediate transport is essential to ensure the safety of both the mother and the baby.
