A nurse is collecting data from an infant who has developmental dysplasia of the hip (DDH). Which of the following findings should the nurse expect?

Inwardly turned foot on the affected side

Lengthened thigh on the affected side

Absent plantar reflexes

Asymmetric thigh folds

Answer and Explanation

Correct Answer : A,D

A. Inwardly turned foot on the affected side.

This finding is consistent with DDH. In infants with DDH, the affected leg may appear shortened and rotated inwardly due to hip instability or dislocation.

B. Lengthened thigh on the affected side.

This finding is not typically associated with DDH. In fact, the affected thigh may appear shortened rather than lengthened due to abnormal positioning of the hip joint.

C. Absent plantar reflexes.

Absent plantar reflexes are not directly related to DDH. Plantar reflexes assess the function of the spinal nerves in the lower extremities and are not typically affected by hip dysplasia.

D. Asymmetric thigh folds.

This finding is consistent with DDH. Asymmetric thigh folds, where one thigh appears fuller or has more skin folds compared to the other, can be indicative of hip dysplasia. The skin folds may be more prominent on the unaffected side due to the displacement of the femoral head on the affected side.

Correct Answer is A

Explanation

A. Upright: This position allows for better expansion of the lungs and improved ventilation-perfusion matching, as gravity helps the diaphragm move downward and expand the lungs. It is often beneficial for patients with respiratory distress or failure.

B. Supine: While lying flat on the back (supine position) may be comfortable for some patients, it can restrict lung expansion, especially in individuals with compromised respiratory function. This position may not be ideal for maximal lung expansion in this scenario.

C. Prone: The prone position involves lying flat on the abdomen. In some cases, especially in adults with acute respiratory distress syndrome (ARDS), prone positioning has been shown to improve oxygenation by optimizing lung mechanics. However, it may not be practical or comfortable for all patients and is not typically used as a first-line intervention in school-age children with pneumonia.

D. Side-lying: While side-lying positions can sometimes improve lung expansion on the dependent side, it may not be as effective as the upright position in maximizing lung expansion, especially in cases of respiratory failure.

A. Machine like murmur B. Chronic hypoxemia C. Cyanosis with crying D. Weak pulse

Correct Answer is A

Explanation

A. Machine-like murmur.

This option is correct. A characteristic clinical manifestation of a large patent ductus arteriosus is a continuous "machine-like" murmur heard on auscultation. This murmur is typically heard best at the upper left sternal border and may radiate to the back.

B. Chronic hypoxemia.

Chronic hypoxemia is not typically a primary manifestation of a large PDA. While PDA can lead to increased pulmonary blood flow and potentially contribute to pulmonary congestion, chronic hypoxemia may not be a prominent feature unless complications such as heart failure develop.

C. Cyanosis with crying.

Cyanosis with crying is more commonly associated with cyanotic congenital heart defects such as tetralogy of Fallot. While PDA can contribute to cyanosis in certain circumstances, it is not typically a consistent clinical manifestation.

D. Weak pulse.

A weak pulse is not typically associated specifically with a large PDA. Infants with PDA may have bounding pulses due to increased blood flow through the ductus arteriosus.
