Answer 8

Physical examination for signs of bleeding, check CBC to follow platelets and other cell lines, advise to avoid contact sports or activities that may cause hits to the head, advise to avoid NSAID/ASA/any meds or herbal supplements with anti-platelet activity, continue regular appointments until counts have recovered

Question 9

Question 11

List two reasons why it is not advisable for parents to rely on “herd immunity” to protect their child from vaccine-preventable diseases. (2)

Answer 11

Outbreaks still occur which overwhelm herd immunity and generally by that time it is too late to vaccinate, some diseases eg tetanus have no herd immunity, choosing not to vaccinate puts others in our orbit at risk eg neonates and pregnant women

Question 19

When prescribing an oral contraceptive, which of the following is true?

a. Close followup — providing an OCP prescription for only two to three months at a time and requiring the patient to return for refills — improves adherence to the OCP and decreases the overall rate of contraceptive failures
b. It is important to be screened for pregnancy before starting OCPs because they can be teratogenic in early pregnancy
c. If breakthrough bleeding occurs during ‘extended use’ or ‘continuous use’ OCP, the pill should be stopped for 4 to 7 days or else the breakthrough bleeding may continue indefinitely

Answer 24

Assent: patient agrees to the proposal but without true consent (may be incompletely informed, may be coerced, may not be capable of consent). Relevant because many of our patients are not able to give consent, yet it is important to still get their assent when possible

Question 25

A patient on your ward is a 10-year-old male who has just been diagnosed with pre-B ALL. Despite the overwhelming likelihood of cure with chemotherapy, his parents refuse.

Question 26

26. In a head lice infestation, what is meant by the term ‘nit’? (1) What is the clinical significance of finding ≥5 nits within 0.6cm of the scalp? (1)

Answer 26

Nits are louse eggs or empty egg shells glued to hair shafts. They can easily indicate past infestation rather than active infestation.

Question 83

What is meant by the term “treatment goal weight” in anorexia nervosa? (3)

Answer 83

TGW is the weight necessary to support:

• puberty
• growth
• development
• physical activity
• psychosocial functioning

Question 84

What are 3 methods a clinician can use to determine the treatment goal weight of a child with anorexia nervosa?

Answer 84

1. TGW based on prior growth curves
   - eg if previously followed 75th percentile, then assume 75th is goal
2. TGW based on height percentile
   - if current height percentile 50th, then aim for 50th of weight
3. TGW based on median BMI for age/sex
   - aim 50th percentile BMI for age and sex
4. TGW based on menstrual threshold + 2kg
   - for girls who stop menstruating at a certain weight

Question 85

Answer 85

Every 3-6mo

Question 86

What is the most important test to consider in cases of anorexia nervosa where there is slowed growth velocity? (1) Why? (2)

Answer 86

Bone age. If Bone age is delayed, then potential for future growth and TGW may be best reflected by premorbid growth pattern to maximize growth potential and allow catch-up growth

Question 87

What are 5 situations in which determining an optimal TGW might be particularly difficult? (5)

Answer 87

History of dieting, Chaotic eating habits, Binge-eating, Compensatory behaviours (fasting, laxative misuse, vomiting), Other mental health conditions, Medication use (stimulants, atypical antipsychotics, etc.), Prior growth info unavailable

Question 88

When treatment goal weight cannot be reliably determined due to clinical uncertainty, what are 3 treatment goals that can be targeted instead? (3)
