Question 26

Which of the following statements about necrotizing fasciitis (NF) is INCORRECT? 1. Crepitus is more strongly associated with GAS-related NF, than with polymicrobial or clostridial NF. 2. Clinical features associated with NF include: severe pain or tenderness (often out of proportion to clinical appearance), toxic appearance, hemodynamic instability, rapid rate of progression, and ‘woody’ induration. 3. GAS-related NF cases are more likely to be associated with a generalized rash, pharyngitis, conjunctivitis, and/or strawberry tongue. 4. Empiric regimens may include either a beta-lactam-beta-lactamase inhibitor (i.e., piperacillin-tazobactam) or a carbapenem, in combination with clindamycin, with consideration of adding vancomycin for MRSA coverage depending on local prevalence and risk factors. 5.

Answer 31

Question 32

What are the three possible approaches toward an autism spectrum disorder diagnostic evaluation? (3)

Answer 32

Approach 1: When a child’s symptoms clearly indicate ASD, an experienced or trained sole paediatric care provider can independently diagnose ASD, based on clinical judgement and DSM-5 criteria, with or without data obtained using a diagnostic assessment tool. However, this approach is not sufficient for accessing specialized services in some Canadian jurisdictions. Approach 2: In the shared care model, a clinician has joint responsibility with another health care provider for patient care, which involves exchanging patient information and clinical knowledge. When a child’s symptom presentation is milder, atypical, or complex, or a child is under 2 years of age, a paediatric care provider may use information from an ASD diagnostic assessment tool, and consult with another health care professional with specialized knowledge (e.g., a psychologist) to inform a diagnosis. Approach 3: In a team-based approach, diagnostic assessment is performed by health care professionals in an interdisciplinary or a multidisciplinary team. While interdisciplinary teams work collaboratively in an integrated, coordinated fashion, multidisciplinary team members work independently from one another but share information, and may (or may not) reach a diagnostic decision by consensus. In some Canadian jurisdictions, only a team-based diagnostic approach is accepted for accessing specialized services.

Question 33

Question 43

What proportion of paediatric prescriptions are off-label in Canada? What does off-label mean? What is the risk of off-label prescribing? (3)

Answer 43

- 80% - Off-label means that it is being prescribed for a condition/population that is not part of product monograph as determined by Health Canada. This does not mean there is not good evidence for use - Off-label prescribing means that children are not receiving the same regulatory protections as adults (companies rely on off-label prescribing to not have to go through expensive/long process of applying for paediatric approvals since it is not required in Canada)

Question 44

Which of the following statements about heated, humidified high-flow nasal cannula (HHHFNC) therapy is INCORRECT? 1. HHHFNC therapy provides warmed, humidified oxygen at flow rates that deliver higher oxygen concentrations and some positive airway pressure compared with standard low-flow therapy 2. Compared with continuous positive airway pressure (CPAP), which delivers gas flow at changing rates to maintain constant and positive intrathoracic pressure during inspiration and expiration, HHHFNC provides a constant, steady flow of gas 3. HHHFNC can deliver 100% O2 to older children and adults and is well-tolerated 4. Extensive paediatric literature exists to support the role of this therapy in reducing need for invasive ventilation and intubation 5. HHHFNC oxygen therapy minimizes or eliminates the inspiration of room air (and the subsequent dilution of supplemental high fraction of inspired oxygen [FiO2] gas) that occurs during low-flow oxygen therapy, using supplemental gas flow rates that ‘wash out’ anatomic dead space

Answer 44

Extensive paediatric literature exists to support the role of this therapy in reducing need for invasive ventilation and intubation

Answer 70

Question 71

You are called to a STAT C-section for a mother with known vasa previa presenting with bleeding at 37 weeks’ gestation. The baby is delivered with poor tone and no cry or spontaneous respirations. He is brought to the warmer. Initial heart rate is 60 bpm, but quickly increases above 100 bpm with effective PPV. After 5 minutes, he gasps intermittently but does not have sustained respirations, requiring continued PPV. He is intubated after requiring PPV for 10 minutes. You assign Apgar scores of 1, 3 and 6 at 1, 5 and 10 minutes, respectively. The arterial cord gas returns at 7.02/78/18/-14.
