Correct Answer: C

Rationale: The correct answer is C because it acknowledges the child's feelings, provides clear instructions, and offers comfort and rewards to help the child cope with the procedure. Choice A is not appropriate as it may create anxiety about the injection. Choice B uses the term 'magic,' which may confuse the child and lead to fear. Choice D introduces a fantasy element that may not be beneficial in preparing the child for the injection.

Correct Answer: D

Rationale: The correct answer is D: Growth restriction in weight, length, and chest and head circumference. Infants born to mothers who smoke during pregnancy exhibit growth failure in weight, length, chest, and head circumference. This growth failure is directly related to the number of cigarettes smoked by the mother. Choices A, B, and C are incorrect because infants exposed to maternal smoking do not tend to be large for gestational age, experience growth restriction in weight only, or be preterm but size appropriate for gestational age.

Correct Answer: A

Rationale: Fever increases metabolic rate, leading to insensible water loss, thus requiring increased fluid intake. Mechanical ventilation, CHF, and increased intracranial pressure generally require fluid restriction rather than increased fluid intake.

Correct Answer: D

Rationale: Early signs of aspirin poisoning include hyperventilation due to the stimulation of the respiratory center and the resultant respiratory alkalosis. Hematemesis, hematochezia, and hyperglycemia can occur later in the poisoning process or may not be directly related to aspirin toxicity.

Correct Answer: C

Rationale: Giardia lamblia is a protozoan parasite known to cause acute diarrhea, often through contaminated water or food. Shigella, Salmonella, and E. coli are bacterial pathogens that also cause diarrhea but are not parasites.
