Correct Answer: D

Rationale: Administering oxygen and massaging the uterus are appropriate interventions to manage postpartum bleeding. Oxygen helps support tissue perfusion, and uterine massage can aid in uterine contraction, controlling bleeding. These actions are indicated when the mother experiences moderate vaginal bleeding post-delivery, as described in the scenario. Careful monitoring for signs of shock should continue while these interventions are implemented to ensure the mother's condition remains stable. Choices A and B are incorrect because packing the vagina with sterile dressings is not recommended for postpartum bleeding unless it is severe and immediate action is needed, while massaging the uterus is a proactive approach and should not be delayed until signs of shock develop. Choice C is also incorrect as rapid transport is not the primary intervention in this scenario where the mother is conscious, alert, and stable, and the focus should be on immediate management of the bleeding.

Correct Answer: D

Rationale: When assessing a small child's level of responsiveness, the most appropriate method is to tap the child and shout, 'Are you okay?' This approach is more likely to elicit a response from the child, providing a direct assessment of their level of consciousness and responsiveness. Palpating for a radial pulse (Choice A) is not the most direct method for assessing responsiveness in a child. Shouting at the child (Choice B) may startle them and not provide an accurate assessment. Asking the parent (Choice C) does not directly evaluate the child's responsiveness.

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.

Correct Answer: D

Rationale: During the assessment of a 30-year-old female in labor, the EMT should be aware that delivery is imminent if she is crowning. Crowning indicates that the baby's head is visible at the vaginal opening, signaling that the birth is progressing rapidly and the baby will soon be delivered. This is a critical moment that requires preparedness for the birth process and ensuring a safe delivery environment. Choice A is incorrect because asking the mother when she is expecting to deliver is not relevant when the baby's head is visible at the vaginal opening. Choice B is incorrect as obtaining the patient's medical history is essential for providing appropriate care. Choice C is incorrect because determining the stage of labor by examining the patient is important but recognizing crowning indicates that delivery is imminent and requires immediate action.

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.
