Correct Answer: A

Rationale: In developmental dysplasia of the hip (DDH), one of the key findings is unequal leg length. This occurs due to the dislocation of the hip joint, where the ball is loose in the socket. Limited adduction, the inability to bring the hip and knee towards the midline of the body, is also a common finding in DDH. Diminished femoral pulses are not typically associated with DDH, as it primarily affects the skeletal structure rather than vascular supply. Symmetrical gluteal folds are normal in infants and do not indicate DDH, as asymmetry in gluteal folds can be a sign of hip dislocation.

Correct Answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

Correct Answer: C

Rationale: Placing the patient on a pressure-relieving mattress is crucial to decrease the risk of skin breakdown, especially with significant edema and ascites. Adequate dietary protein intake is essential in patients with ascites to improve oncotic pressure and prevent malnutrition. Repositioning the patient every 4 hours alone may not be sufficient to prevent skin breakdown, especially in areas prone to pressure ulcers. Performing passive range of motion exercises is important for maintaining joint mobility but does not directly address the risk of skin breakdown associated with prolonged pressure on vulnerable areas.

Correct Answer: D

Rationale: The correct action for a patient diagnosed with asymptomatic nonalcoholic fatty liver disease (NAFLD) would be to review the patient's current medication list. This is important because certain medications can increase the risk for NAFLD, and they should be identified and possibly eliminated. Teaching about symptoms of variceal bleeding is not necessary as variceal bleeding is not a concern in a patient with asymptomatic NAFLD. Drawing blood for hepatitis serology testing is not indicated as NAFLD is not associated with hepatitis. Discussing the need to increase caloric intake is also not appropriate since weight loss is usually recommended in the management of NAFLD.

Correct Answer: B

Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.
