Which of the following organisms is responsible for the development of rheumatic fever?
- A. Streptococcal pneumonia
- B. Haemophilus influenza
- C. Group Aß-hemolytic streptococcus
- D. Staphylococcus aureus
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.

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 hospitalized child with nephrosis is receiving high doses of prednisone. which of the following is an appropriate nursing goal related to this?
- A. prevent infection.
- B. stimulate appetite.
- C. detect evidence of edema.
- D. assist in raising osmotic pressure.
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.
Which of the following is an intraoperative outcome for a patient undergoing an inguinal hernia repair?
- A. Verbalizes fears
- B. Demonstrates leg exercises
- C. Maintains skin integrity
- D. Explains deep breathing exercises
Correct Answer: C
Rationale: Intraoperative outcomes refer to the immediate goals and conditions that are assessed during a surgical procedure. Maintaining skin integrity is a crucial intraoperative outcome for a patient undergoing an inguinal hernia repair surgery. This outcome focuses on ensuring that the patient's skin remains intact, without any damage or breakdown during the surgical procedure. It involves proper positioning of the patient, adequate support to vulnerable areas, and meticulous monitoring of the skin throughout the surgery to prevent any pressure injuries or skin trauma. Other outcomes listed, such as verbalizing fears, demonstrating leg exercises, and explaining breathing exercises, are more pertinent to preoperative or postoperative care rather than intraoperative outcomes.

The nurse is caring for a 5-year-old child with impetigo contagiosa. The parents ask the nurse what will happen to their child's skin after the infection has subsided and healed. Which answer should the nurse give?
- A. There will be no scarring.
- B. There may be some pigmented spots.
- C. It is likely there will be some slightly depressed scars.
- D. There will be some atrophic white scars.
Correct Answer: A
Rationale: Impetigo contagiosa typically does not leave scarring once it has subsided and healed. This skin infection primarily affects the superficial layers of the skin and does not cause damage deep enough to result in scarring. While there may be some temporary pigmented spots or mild changes in skin color after the infection resolves, scarring is not a common outcome of impetigo contagiosa in most cases. Thus, the nurse should reassure the parents that their child's skin is not likely to have any scarring after the infection has healed.
