The nurse is completing an assessment on a 3-month-old male who is in the pediatrician’s office because the infant had a fever and diarrhea for the past 2 days. The infant’s history reveals his mother had preeclampsia and the child was delivered via emergency C-section prematurely at 30 weeks gestation. The nurse performs a history and assessment and finds the following. Which assessment findings require follow-up by the nurse? (Select all that apply)

Choice A reason:

Compartment syndrome is a condition where increased pressure within a muscle compartment leads to decreased blood flow, which can cause muscle and nerve damage. It is typically associated with severe trauma, fractures, or crush injuries. The symptoms include severe pain, swelling, and decreased sensation or movement in the affected limb. In this case, the child’s symptoms of redness, swelling, and tenderness following a spider bite, along with an elevated WBC, are more indicative of an infection rather than compartment syndrome.

Choice B Reason:

Osteomyelitis is an infection of the bone, which can occur following an injury or infection elsewhere in the body. The symptoms include redness, swelling, tenderness, and pain in the affected area, along with fever and elevated WBC. Given the child’s history of a spider bite and the presence of redness, swelling, tenderness, and elevated WBC, osteomyelitis is the most likely diagnosis. The unremarkable X-ray does not rule out osteomyelitis, as early stages of the infection may not show changes on X-ray.

Choice C Reason:

Osteogenesis imperfecta, also known as brittle bone disease, is a genetic disorder characterized by fragile bones that break easily. It is not associated with infections or elevated WBC. The symptoms of osteogenesis imperfecta include frequent fractures, blue sclerae, and hearing loss. The child’s symptoms of redness, swelling, and tenderness following a spider bite, along with an elevated WBC, are not consistent with osteogenesis imperfecta.

Choice D Reason:

Juvenile idiopathic arthritis (JIA) is a type of arthritis that occurs in children. It is characterized by persistent joint inflammation, pain, and swelling. While JIA can cause joint tenderness and swelling, it is not typically associated with a recent injury or infection, such as a spider bite. Additionally, JIA does not usually cause elevated WBC. The child’s symptoms are more indicative of an infection, making osteomyelitis the more likely diagnosis.

Choice A reason:

Decreased abdominal distention is not typically a sign of appendicitis perforation. In fact, perforation often leads to increased abdominal distention due to the release of intestinal contents into the abdominal cavity, causing inflammation and swelling. Therefore, this choice is incorrect.

Choice B reason:

Anorexia, or loss of appetite, is a common symptom of appendicitis but not specifically indicative of perforation2. While anorexia can be present in cases of perforation, it is not a definitive sign. The sudden relief of pain is a more critical indicator of perforation, as it suggests the appendix has ruptured, temporarily relieving pressure.

Choice C reason:

Bradycardia, or a slow heart rate, is not a typical sign of appendicitis perforation. In fact, appendicitis and its complications, such as perforation, are more likely to cause tachycardia (an increased heart rate) due to pain and infection. Therefore, this choice is incorrect.

Choice D reason:

Sudden relief from pain is a classic sign of appendicitis perforation. When the appendix ruptures, the pressure inside the appendix is relieved, leading to a temporary decrease in pain. However, this is followed by a rapid onset of severe pain as the contents of the appendix spread throughout the abdominal cavity, causing peritonitis. This sudden change in pain is a critical indicator that the appendix has perforated and requires immediate medical attention.
