Which of the following organisms is responsible for the development of rheumatic fever?

Correct Answer: C

Rationale: Rheumatic fever is an inflammatory disease that can develop after an untreated or inadequately treated infection with group Aß-hemolytic streptococcus bacteria, particularly Streptococcus pyogenes. This bacteria causes strep throat, which if left untreated, can lead to complications such as rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain. It is important to promptly treat streptococcal infections with antibiotics to prevent the development of rheumatic fever.

Correct Answer: C

Rationale: Placing an undershirt between the skin and the Pavlik harness is done to prevent skin abrasions and irritation caused by the harness rubbing directly against the skin. The undershirt acts as a protective layer, reducing the likelihood of skin sensitivity or damage due to the continuous contact with the harness. This is particularly important for infants or young children who may have delicate skin that is more prone to irritation. By using an undershirt, caregivers can help ensure greater comfort for the child while wearing the Pavlik harness and reduce the risk of any skin-related complications.

Correct Answer: D

Rationale: The Anti Streptolysin O titer (ASOT) is a test used to detect antibodies produced by the body in response to a recent streptococcal infection. A positive ASOT result can be seen in various conditions such as tonsillitis, glomerulonephritis, and Rheumatic fever (RF), which are all associated with streptococcal infections. Therefore, the correct answer is D, as all of these conditions can lead to a positive ASOT result.

Correct Answer: A

Rationale: High doses of prednisone suppress the immune system, putting the hospitalized child at an increased risk for infections. Therefore, an appropriate nursing goal related to this situation would be to prevent infection by implementing measures such as hand hygiene, maintaining a clean environment, and monitoring for signs and symptoms of infection. It is crucial to protect the child from acquiring additional illnesses while undergoing treatment for nephrosis.

Correct Answer: B

Rationale: It is normal for newborns to lose weight in the first few days of life, typically up to 10% of their birth weight. In this case, the newborn's weight loss from 7 pounds, 8 ounces to 6 pounds, 15 ounces is within the expected range. It is important for the nurse to reassure the mother that this weight loss is normal and to encourage continued breastfeeding on demand to support newborn hydration and nutrition. There is no need for supplemental feedings at this point unless there are other signs of feeding issues or concerns.
