Bone age is advanced:
A) in case of hypothyreoidism
B) amongst children living in bad social conditions
C) in congenital adrenal hyperplasia
D) in familiar dwarfism
E) as a result of glucocorticoid application

A

ANSWER
C) in congenital adrenal hyperplasia

EXPLANATION
Bone age is advanced in congenital adrenal hyperplasia (CAH). The diagnosis of no-salt-losing CAH, especially in boys, is often made at the age of 3-6 years, by this time, bone maturation can even exceed the chronological age of 5 years. Appropriate treatment slows down growth; however, if the bone age is already equivalent of a 12-year-old, spontaneous gonadotropin-dependent puberty can occur, because hydrocortison therapy has already repressed the production of adrenal androgens, allowing the production of gonadotropins by the hypophysis.

Assuming dehydration of 5%, which is the easiest way to check for improvement?
A) measuring the child’s weight
B) determining serum osmolality
C) measuring central venous pressure
D) monitoring blood pressure

A

ANSWER
A) measuring the child’s weight

EXPLANATION
Measuring the weight is the most reliable method for assessing the degree of dehydration and controlling the rehydration. In an optimal case, the parents know the child’s weight before the fluid and electrolyte loss. We compare that with the current measured value. The change in serum osmolality can only be used to determine the type of dehydration. Arterial and venous pressure are only relevant in severe dehydration.

If yellow amniotic fluid is detected during delivery, first to do is:
A) early umbilical cord ligature
B) termination of the delivery
C) UH examination of the mother’s liver after delivery
D) UH examination of the newborn liver after delivery

A

ANSWER
A) early umbilical cord ligature

EXPLANATION
In Rh-incompatibility, bilirubin and other pigments, so-called bilirubinoids could build up in the amniotic fluid, turning it to yellow. Blood transfusion during delivery of the placenta to the newborn increases the degree of hyperbilirubinemia even further during the first days. That is why the early umbilical cord ligature is recommended.

In a six-week-old infant, we are thinking of muscle tone disturbance when:
A) does not raise his head
B) does not turn
C) crosses the lower extremities during the elemental walk
D) do not sit

A

ANSWER
C) crosses the lower extremities during the elemental walk

EXPLANATION
A muscle tone disorder is suggested in infants, when it crosses the lower limbs at six weeks of age when triggering an elemental walk. The infant’s movements are organized by the elemental motion patterns of the brain that developed during the fetal life in the nervous system. Such elemental movement pattern is the elemental walking. If this leads to a tense muscle tone, it crosses its leg and then it suggests an infantile cerebral paresis.

Physiological weight loss is considered when:
A) the newborn loss 5% of his weight in the first 10 days
B) 20% weight loss during the first week of life
C) loss about 10% of birth weight on the first days of life and it will regain ca. at the 10th day
D) loss up to 200 g after the birth

A

ANSWER
C) loss about 10% of birth weight on the first days of life and it will regain ca. at the 10th day

EXPLANATION
Physiological weight loss is considered when the newborn loss about 10% of birth weight on the first days of life and he will regain it for day 10. The initial weight loss is part of the postnatal adaptation in which several hormones play a role (natriuretic peptide, renin-angiotensin system, prolactin, vasopressin). As a result of these processes the extracellular fluid space is narrowed while the intracellular space extends. This weight loss is usually around 10%, and in healthy, well-feeding babies, usually at the 2nd week of life, with weight gaining, the initial loss is regenerated.

EXPLANATION
Infants usually double their birth weight for 5 months of age. This is, of course, a general approach of weight gaining. But it can be used in practice, since premature babies usually do not reach the 6-7 kg of term baby’s weight for their 5 month old age. Of course, for the purpose of accurate information and registration, the percentile curves developed for the Hungarian population are used.

1) a sudden high fever is a verification of a bacterial infection
2) the rectal temperature is 0.4-0.6 ° C higher than in the armpit
3) physical antipyretic treatments can be used exclusively in infants
4) the occurrence of seizures is elevated in fever

A) 1st, 2nd and 3rd answers are correct
B) 1st and 3rd answers are correct
C) 2nd and 4th answers are correct
D) only the 4th answer is correct
E) all of the answers are correct

A

ANSWER
C) 2nd and 4th answers are correct

EXPLANATION
The cause of a sudden high fever can be a viral or bacterial infection. The rectal temperature is approximately 0,5 ° C higher than in the armpit. In the case of a fever, exceeding 39 °C, physical antipyretic treatment should be considered beside the medication (cooling bath, lukewarm sting) although it is not an up-to-date procedure. The occurrence of febrile seizures is elevated in high temperature.

Q

PED - 1.103
Adolescence for healthy boys begins earlier and lasts longer than girls’ adolescence, so the height of the boys is higher than the height of the girls.

A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
The maturation of the hypothalamus-hypophysis gonad axis occurs later in boys, so the process of adolescence begins later in relation to the girls in the case of boys. For this reason, the boys may grow for a further two years before the beginning of their adolescence, so their height will be higher (2 x 6,5 cm / year = 13 cm).

Q

PED - 1.105
Breast milk is the most preferred nutrition for all newborns because the nutritional content is the most suitable for any newborn of any weight or maturity.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
C) the first is correct in itself, the second is incorrect

EXPLANATION
The statement is true, breast milk is the “gold standard” of nutrition. The justification is bad because premature babies need more protein with protein-enriched female milk

54
Q

PED - 1.106
Cow milk protein allergy can not occur in breast milk feeding because protein with a foreign antigen is found only in low concentrations in breast milk.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
The low concentration of antigen may also be sufficient to induce allergy, so the reasoning is good, not the statement.

55
Q

PED - 1.110
In breastfed infants, at an acute infectious diarrhoea, breastfeeding must be interrupted, as it contains 7 % lactose, which, associated with reduced lactase enzyme levels, can increase the diarrhoea
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
In the case of an acute diarrhoea in a breastfeeding infant, the interruption of breastfeeding is not necessary, because the lack of mother milk is unfavourable for the course of the disease, the second part of the question is true in itself.

56
Q

PED - 1.111
Even a well-feeding infant needs regular tea consumption, because a healthy baby has other fluid needs in addition to breastmilk.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
E) both are incorrect

EXPLANATION
A healthy, well-feeding infant’s fluid and nutrition needs are met by mother’s milk, in this case, additional tea intake is not necessary, the excess tea consumption may reduce the infant’s appetite due to its sugar content, so it should be avoided (in higher temperatures, moderate tea consumption is not opposed).

57
Q

PED - 1.112
The breastfeeding infant’s weight development is faster than one on formula, because the composition of breast milk changes during lactation.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
The formula-fed infant’s weight development is faster than one on breastfeeding. (Maybe he/she could consume more formula from the bottle than he/she actually needs) It is true that the composition of breast milk changes during lactation.

58
Q

PED - 1.114
During the treatment of hyperosmotic dehydration cerebral oedema or specific central nervous system lesions can develop, because hyperosmotic dehydration leads to blood hyperosmolarity.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
B) both are correct, but there is no cause-effect relationship between them

EXPLANATION
The cause of hyperosmotic dehydration can be water deficiency and / or an elevated level of special substances in the blood (eg hyperglycaemia). The aim of the treatment is the slow, progressive reduction of hyperosmolarity. The too fast rehydration can lead to cerebral oedema and specific central nervous system lesions.

59
Q

PED - 1.115
Pre-, peri- or postnatal lesions can often be detected in the background of childhood epilepsy, because structural changes in the brain can lead to epilepsy.

C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
Cerebral damage or structural changes are rarely found in the background of childhood epilepsy-syndromes. But structural changes in the brain can lead to epilepsy.

Q

PED - 1.118
Atropine should not be administered in organic phosphate poisoning, as it can cause dry mouth.
A) both are correct, they have a causal relationship between them
B) both are correct, but there is no cause-effect relationship between them
C) the first is correct in itself, the second is incorrect
D) the first is incorrect, the second is correct in itself
E) both are incorrect

A

ANSWER
D) the first is incorrect, the second is correct in itself

EXPLANATION
One of the most important antidotes for organic phosphate poisoning is atropine, which is to be used only until the appearance of dry mouth (xerostomia) and flushing, so the statement is incorrect. The administration of atropine is followed by dry mouth, so the reason and explanation are true in themselves.
