Judy brings her son Henry, aged eight weeks, to see you as he has a swelling in his left groin. Henry was born at 39 weeks gestation after the spontaneous onset of labour and by normal vaginal delivery. The antenatal course was uneventful and obstetric ultrasonography for fetal development was reported as normal. He has been well since birth. You suspect that Henry has an inguinal hernia and you explain to Judy that inguinal hernias are very common.
What is the prevalence of inguinal hernias in full-term infants?
Given Henry’s age, what is the recommended referral time frame for him regarding the inguinal hernia?
- 0–2 weeks
- 2–4 weeks
- 1–3 months
- 3–6 months
Judy asks you whether Henry needs an ultrasound to investigate the inguinal hernia. You explain to her that this particular condition does not require a diagnostic ultrasound.
In which one of the following conditions is a diagnostic ultrasound likely to be included as part of the routine workup?
- Testicular maldescent
- Epigastric hernia
- Umbilical hernia
Judy then asks you about Henry’s sister Helen, who is two years of age. Judy has noticed recently that Helen has a firm, pea-shaped, midline lump 1 cm above her umbilicus. It is prominent when Helen stands up but cannot be seen when she lies down. Helen is thriving and Judy has no other concerns about her.
What is the most likely diagnosis given this history?
- Epigastric hernia
- Divarication of the recti
- Umbilical hernia
- Inguinal hernia
What is the most appropriate management for Helen?
- Urgent referral written today
- Non-urgent referral written today
- Defer referral until after Helen is three years of age
- Advise that referral is never required for this condition
Joan, one of your regular patients, makes an appointment because she is concerned about her daughter Clare’s sleeping patterns. Clare is a healthy child, aged two years, whom you know well. You explain to Joan that there are many interventions that can improve a child’s sleep, including establishing good sleep hygiene.

- Setting a regular bedtime
- Keeping the bedroom quiet
- Keeping the bedroom well lit

- Ensuring a regular morning wake time
You discuss other management strategies designed to improve to sleep. Joan is especially interested in the idea of ‘extinction’.
Which one of the following is the most correct definition of ‘extinction’ in the context of sleep problems?
- Parents settle the child in the cot or bed by patting or stroking them until they are quiet but not asleep, and then leave the room.
- Parents place a chair or camp bed next to their child’s cot or bed; initially the parents stay with them as they fall asleep at the start of the night, then gradually withdraw their presence from the child’s room.
- Parents allow the child to have a ‘pass out’ at bedtime for one acceptable request but once the pass is used, parents do not respond to further requests.
- Parents systematically ignore inappropriate behaviours when the child is placed in bed.
Clare has a brother, Harry, aged 14 years. Joan tells you she is also concerned about Harry’s sleep. Harry has difficulty falling asleep until very late at night. When he goes to bed at a time he chooses, he can usually fall asleep easily. He is otherwise well and has no medical or psychological conditions.
What is the most likely cause for Harry’s sleep problems?
- Delayed sleep phase disorder
- Anxiety-related insomnia
- Limit-setting disorder
- Physiological insomnia
You suggest ‘bedtime fading’ to improve Harry’s sleep.

- Vary the morning wake time.
- Encourage daytime naps.
- Avoid the use of technology with screens before bed.
- Increase natural light exposure in the evening.

- Timeout alone
- Timeout and withdrawal of privileges
