Question 1 of 5

Anaphylactic shock is characterized by which of the following:

A. Airway obstruction B. Decreased systemic vascular resistance C. Generalized vasoconstriction D. Hypovolemia

Correct Answer: B

Rationale: Anaphylaxis leads to massive vasodilation and decreased systemic vascular resistance, resulting in hypotension and shock.

Question 2 of 5

Obstructive shock is characterized by which of the following:

A. Mechanical obstruction of ventricular outflow B. Airway obstruction C. Generalized vasoconstriction D. Hypovolemia

Correct Answer: A

Rationale: Obstructive shock occurs due to mechanical barriers to blood flow, such as cardiac tamponade or pulmonary embolism.

Question 3 of 5

Question 4 of 5

Conduct disorder in childhood and adolescence is associated with all of the following EXCEPT

A. antisocial behavior B. criminality in the father C. physical abuse D. marital discord within the home

Correct Answer: D

Rationale: Conduct disorder is linked to antisocial behavior, physical abuse, and family dysfunction. However, criminality in the father alone does not directly predict conduct disorder; other factors must also contribute.

Question 5 of 5

A 5-year-old underwent a tonsillectomy and an adenoidectomy under general anesthesia. The parents tell you that the anesthesiologist said that she â€œfought the mask and cried a lotâ€ on induction. You are the pediatrician for this child, and 8 days after surgery, the parents call to report that the child, who previously slept well at night, now awakens nightly screaming with bad dreams. She is more irritable and cranky than before surgery and has angry outbursts. She is more â€œclingyâ€ and wants her parents to cuddle her frequently. She reports that in her dreams, she canâ€™t move, there is a tube in her throat, and she feels the surgeon cutting her throat. A review of her anesthetic record suggests an uneventful intraoperative course, with stable vital signs. All of the following statements about this situation are true EXCEPT

A. this is an extreme reaction and suggests a severe underlying tendency toward psychiatric illness B. traumatic induction of anesthesia can commonly produce behavioral changes for several weeksâ€”in the majority of cases, these resolve within 4-6 weeks C. parental presence for mask induction of anesthesia may reduce the distress of induction for some children and may reduce the incidence of some postoperative behavioral changes D. intraoperative awareness can occur during general anesthesia and could possibly account for the content of her dreams and some of the severity of these behavioral changes

Correct Answer: A

Rationale: The described reaction, while distressing, is not necessarily indicative of severe psychiatric illness but rather a response to traumatic anesthesia induction.
