The nurse is assessing a 2-week-old for signs of DDH. The nurse should expect the infant to have which of the following?

Correct Answer: C

Rationale: Developmental dysplasia of the hip (DDH) is a condition where the hip joint does not develop normally. In infants, one of the signs of DDH is the presence of asymmetry of gluteal (buttock) and thigh folds. This is due to the dislocated or subluxed hip being positioned differently than the healthy hip. The nurse should look for this sign during the assessment of a 2-week-old infant to help identify potential hip joint problems early on. Excessive hip abduction, femoral lengthening of an affected leg, and pain when lying prone are not typical signs of DDH in a 2-week-old infant.

Correct Answer: D

Rationale: Rheumatic fever is an inflammatory disease that can develop as a complication of inadequately treated streptococcal infections, especially streptococcal throat infections caused by group A streptococcus bacteria. The bacteria trigger an abnormal immune response in susceptible individuals, leading to the development of rheumatic fever. The other choices are not accurate. Glomerulonephritis is a separate condition associated with certain types of streptococcal infections but not with rheumatic fever. Symptoms of rheumatic fever can persist even after the fever has subsided, and it is important for children with rheumatic fever to follow proper treatment and rest guidelines as advised by healthcare providers. It is crucial for individuals with rheumatic fever to avoid activities that could strain the heart until the condition has been properly managed.

Correct Answer: C

Rationale: Ortolani's sign is a physical exam maneuver used to detect congenital hip dislocation in infants. When performing Ortolani's sign, the nurse gently abducts the hips and feels the femoral head slipping back into the acetabulum. This is considered a positive finding and suggests the presence of hip dysplasia. Barlow's test, on the other hand, involves gently adducting the hip to feel for instability and potential dislocation. Jackson's sign is a maneuver for detecting hip dislocation by observing leg length discrepancy. Trendelenburg's sign is a test for hip abductor weakness. Hematuria is the presence of blood in urine and is not related to hip exams or signs.

Correct Answer: A

Rationale: The anterior fontanel, also known as the bregma, is the larger of the two fontanels located on the baby's skull. It is diamond-shaped, with the sutures meeting in the center to create a space that is soft and slightly depressed. While it is diamond-shaped when looking at the intersection of the sutures, when palpated or touched by a nurse, it often feels more circular due to the softness of the fontanel. It is important for nurses to monitor the fontanels for normal closure and development in newborns.

Correct Answer: B

Rationale: The stump of the umbilical cord usually separates from the baby's belly button within 10 to 14 days after birth. During this time, it is important to keep the area clean and dry to prevent infection. Once the stump falls off, a small open wound may be left behind, which should also be kept clean and dry until it completely heals. It is normal for a small amount of blood or discharge to be present during this process, but if there are signs of infection such as redness, swelling, or foul odor, it is important to contact a healthcare provider for further evaluation and treatment.
