Which factor is most important in predisposing toddlers to frequent infections such as otitis media, tonsillitis, and upper respiratory tract infections?
Respirations are abdominal
Pulse and respiratory rates are slower than those in infancy
Defense mechanisms are less efficient than those during infancy
The presence of short, straight internal ear/throat structures and large tonsil/adenoid lymph tissue
The Correct Answer is D
This is because toddlers continue to have the short, straight internal ear canal of infants.
The lymphoid tissue of the tonsils and adenoids continues to be relatively large. These two anatomic conditions combine to predispose the toddler to frequent infections.
Choice A is wrong because respirations are abdominal. This does not affect the susceptibility to infection.
Choice B is wrong because pulse and respiratory rates are slower than those in infancy. This also does not affect the susceptibility to infection.
Choice C is wrong because defense mechanisms are less efficient than those during
infancy. This is not true, as the defense mechanisms are more efficient compared with those of infancy.

Correct Answer is ["B","C"]
Explanation
The child’s care should include adequate hydration and pain management. The management of an acute event of a vaso-occlusive crisis is the use of potent analgesics (opioids), rehydration with normal saline or Ringer’s lactate, treatment of malaria (whether symptomatic or not) using artemisinin combination therapy, and the use of oxygen via face mask, especially for acute chest syndrome.
Choice A is wrong because correction of acidosis is not a specific intervention for the vaso- occlusive crisis.
Acidosis may occur as a complication of sickle cell disease, but it is not the primary cause of the crisis.
Choice D is wrong because the administration of heparin is not recommended for the vaso-occlusive crisis.
Heparin is an anticoagulant that may increase the risk of bleeding and does not prevent or treat the sickling process.
Normal ranges for hemoglobin are 11.5 to 15.5 g/dl for children after 2 years of age.
Normal ranges for reticulocyte count are 0.5% to 1.5% for adults and 0.5% to 2.5% for children.
Correct Answer is D
Explanation
Diabetes insipidus is a disorder of the posterior pituitary gland that causes a deficiency of antidiuretic hormone (ADH). This leads to excessive urination (polyuria) and excessive thirst (polydipsia) as the body tries to balance the fluid loss. These symptoms may be so severe that the child does little other than drink and urinate.
Choice A is wrong because oliguria means decreased urine production and is not associated with diabetes insipidus.
Choice B is wrong because glycosuria means glucose in the urine and is associated with diabetes mellitus, not diabetes insipidus.
Choice C is wrong because nausea and vomiting are associated with inappropriate ADH secretion (SIADH), which causes fluid retention and hyponatremia, not diabetes insipidus.
