Congenital diaphragmatic hernia (CDH) can be diagnosed on prenatal ultrasonography (between 16 and 24 wk of gestation) in > 50% of cases. Findings on ultrasonography may include the following EXCEPT

Correct Answer: D

Rationale: Oligohydramnios is not typically associated with CDH. The other findings are common on prenatal ultrasound in CDH cases.

Correct Answer: A

Rationale: Cardiogenic shock typically presents with increased central venous pressure due to impaired cardiac output.

Correct Answer: D

Rationale: The rationale is that tuberculin skin tests (TST) may give false-negative results immediately after arrival due to factors like recent travel stress or malnutrition. Therefore, repeating the test after 3-6 months ensures more accurate results. The other tests are generally required to be repeated for ongoing monitoring.

Correct Answer: D

Rationale: Advanced life support (ALS) includes airway management, vascular access, fluid resuscitation, and defibrillation, but does not specifically focus on treating arrhythmias, which is a specialized intervention.

Correct Answer: D

Rationale: High cholesterol is not a diagnostic criterion for systemic lupus erythematosus; it is unrelated to the disease process.

Correct Answer: B

Rationale: GCS is calculated as Eye Opening (2) + Verbal Response (4) + Motor Response (4) = 10, indicating moderate brain injury.

Correct Answer: C

Rationale: Exposure to non-TB mycobacteria can cause cross-reactivity, leading to a false-positive tuberculin skin test.

Correct Answer: B

Rationale: Intellectual deficits in autism vary widely; some individuals exhibit superior abilities in certain areas. Superior intellectual deficits are not a defining feature of ASD.

Correct Answer: C

Rationale: The recommended chest compression rate for infants during CPR is at least 100 per minute to ensure adequate perfusion and circulation during resuscitation.
