Why place an undershirt between the skin and the Pavlik harness?
- A. To keep the skin moist
- B. To prevent infection caused by pins of the Pavlik harness
- C. To prevent skin abrasions and irritation by the harness
- D. To keep the skin clean
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.
A client is admitted to an acute care facility with a myocardial infarction. During the admission history, the nurse learns that the client also has hypertension and progressive systemic sclerosis. For a client with this disease, the nurse is most likely to formulate which nursing diagnosis?

- D. Ineffective thermoregulation
Correct Answer: A
Rationale: For a client with progressive systemic sclerosis, also known as Scleroderma, the nurse is most likely to formulate a nursing diagnosis related to the risk for impaired skin integrity. Scleroderma is a chronic connective tissue disease that can lead to changes in skin texture and thickness, making the skin more prone to breakdown, ulcers, and impaired wound healing. Therefore, assessing and addressing the risk for impaired skin integrity is essential to prevent complications in clients with Scleroderma. While the other options may also be relevant considerations for this client, the priority nursing diagnosis in this case would be related to maintaining skin integrity.

It is important to note that while acidic juices can be beneficial in some cases, they should not be relied upon as the sole preventive measure for UTIs. Other important preventive measures include staying hydrated, practicing good hygiene, and urinating before and after intercourse.
