Which of the following statements regarding 2-rescuer child CPR is correct?

Correct Answer: B

Rationale: The correct statement regarding 2-rescuer child CPR is to compress the chest with one or two hands to a depth equal to one-half to one third the diameter of the chest. This technique ensures effective chest compressions without causing excessive damage to the chest. Choice A is incorrect because allowing the chest to fully recoil between compressions is essential to facilitate optimal blood flow during CPR. Choice C is incorrect as it describes a compression to ventilation ratio of 30:2, which is not the recommended ratio for child CPR. Choice D is incorrect as a compression to ventilation ratio of 15:2 is not standard practice for child CPR, and pauses in compressions are necessary to provide ventilations effectively.

Correct Answer: D

Rationale: The correct answer is D. The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. At around five months of age, these reflexes are replaced by voluntary movements as part of the normal developmental process. Choices A, B, and C are incorrect. Choice A suggests delaying a decision until further assessment, which is not necessary as the disappearance of these reflexes is a normal part of infant development. Choice B implies a developmental delay, which is not the case as these reflexes naturally disappear with age. Choice C recommending additional sensory stimulation is unnecessary and not the reason for the absence of these reflexes.

Correct Answer: D

Rationale: The classification is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation between acyanotic and cyanotic defects. Choice A is incorrect because the system is not solely based on explaining hemodynamics. Choice B is incorrect because the classification is not based on the ease of identifying children with cyanotic defects. Choice C is incorrect because cyanosis can indeed be present in children with congenital heart defects, especially acyanotic defects that may lead to cyanosis under certain circumstances.

Correct Answer: A

Rationale: Monitoring the temperature of a child with minimal change nephrotic syndrome is crucial to detect early signs of infection. Infection is a common complication in nephrotic syndrome, and fever can be an early indicator. Hypertension (choice B) is not typically associated with nephrotic syndrome. Encephalopathy (choice C) is a neurological complication and would present with altered mental status rather than a change in temperature. Edema (choice D) is a common symptom of nephrotic syndrome but is not typically monitored through temperature assessment.

Correct Answer: C

Rationale: Visible peristalsis and weight loss are classic clinical manifestations of pyloric stenosis. The obstruction at the pyloric sphincter causes visible peristalsis as the stomach tries to push food through the narrowed opening, leading to the appearance of waves across the abdomen. Weight loss occurs due to poor feeding and frequent vomiting associated with pyloric stenosis. Choices A, B, and D are incorrect. Abdominal rigidity and pain on palpation, rounded abdomen and hypoactive bowel sounds, as well as distention of the lower abdomen and constipation are not typically seen in pyloric stenosis.
