While assisting a full-term pregnant female in delivering her newborn, at what point should the paramedic consider suctioning the infant's nose and mouth?

Correct Answer: B

Rationale: The correct answer is B: When the newborn's head is delivered. Suctioning at this point helps clear any amniotic fluid or mucus from the infant's airway, preventing potential breathing difficulties. Suctioning after the head is delivered but before the body helps ensure a clear passage for the baby's first breath. Choice A is incorrect because meconium staining alone is not a definitive indication for suctioning, and it is more crucial to maintain a clear airway during delivery. Choice C is incorrect as waiting until the entire delivery is complete may delay clearing the airway, posing risks to the newborn's breathing. Choice D is incorrect as drying and stimulating the newborn are important steps but should not delay airway clearance, which is crucial for the baby's first breath.

Correct Answer: B

Rationale: The correct answer is B: An inferior wall myocardial infarction. The EKG findings of ST elevation in leads II, III, and aVf indicate an inferior wall MI. Leads II, III, and aVf correspond to the inferior wall of the heart supplied by the right coronary artery. This pattern of ST elevation is indicative of myocardial ischemia or infarction in this region. The symptoms of chest pain radiating to the jaw and left arm are also classic for a heart attack. A: A possible aortic dissection is unlikely in this case as the EKG findings specifically point towards a myocardial infarction rather than aortic pathology. C: A possible pulmonary embolus is less likely as the EKG findings are more consistent with a myocardial infarction, and pulmonary embolism typically presents with symptoms such as shortness of breath and chest pain. D: A septal wall myocardial infarction is not supported by the

Correct Answer: C

Rationale: The correct answer is C: She is an emancipated minor granted by the court. This is true because an emancipated minor is legally recognized as an adult and can make medical decisions without parental consent. Emancipation typically requires a court order that grants the minor the legal status of an adult. In this case, the patient is sixteen and does not need parental consent because she has been granted emancipation by the court. Choice A (implied consent) is incorrect because implied consent generally applies in emergency situations where the patient is unable to provide consent. In this case, the patient is conscious and capable of providing consent. Choice B (not an American citizen) is incorrect because citizenship status does not impact a minor's ability to provide consent for medical treatment. Choice D (orphaned minor living alone) is incorrect because being orphaned does not automatically grant a minor the legal status to make medical decisions without parental consent.

Correct Answer: B

Rationale: The correct answer is B: To prevent atelectasis from occurring at the end of exhalation. Pursed lips and sighing-type respirations help create positive pressure in the airways, preventing collapse of small airways and maintaining lung inflation. Pursed lips prolong exhalation, which helps keep airways open, reducing the risk of atelectasis. Choices A, C, and D are incorrect because pursed lips and sighing-type respirations do not directly relate to expelling foreign bodies, preventing pleural friction rub, or increasing the size of air sacs in the lungs.

Correct Answer: D

Rationale: The correct answer is D because performing diagnostic peritoneal lavage or a FAST exam is crucial in evaluating for intra-abdominal injuries after blunt trauma. This will help determine if there is internal bleeding or organ damage requiring immediate intervention. A: Performing external fixation of the pelvis is not the immediate priority in this scenario as internal injuries need to be ruled out first. B: Obtaining abdominal and pelvic CT-scans may provide detailed information, but they are time-consuming and not the immediate priority for a potentially unstable patient. C: Performing arterial embolization of the pelvic vessel is not the initial priority as the patient's internal injuries need to be evaluated first.
