Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The major role of the complement system is to work in conjunction with
Correct Answer: A
Rationale: Rationale: The complement system is a group of proteins that enhance the ability of antibodies and phagocytic cells to clear pathogens. Choice A is correct because the C8 and C9 components of the complement system form the membrane attack complex which lyses cells. Choices B, C, and D are incorrect because the complement system primarily functions independently of the major histocompatibility complex, antibodies for opsonization, and T-cell receptor for lymphokine production.
Question 3 of 5
Which immunoglobulin is the principal one found in secretions such as milk?
Correct Answer: C
Rationale: The correct answer is C: IgA. IgA is the principal immunoglobulin found in secretions like milk due to its role in mucosal immunity. IgG is mainly found in the blood and provides systemic immunity. IgM is the first antibody produced during an immune response. IgD is primarily found on the surface of B cells and is involved in B cell activation. IgA is the most abundant immunoglobulin in mucosal secretions, making it the principal one found in milk.
Question 4 of 5
Which statement indicates that the patient needs further instruction about application of ice to a sprain?
Correct Answer: B
Rationale: The correct answer is B because keeping ice on the knee for the rest of the day can lead to skin damage or frostbite. Choice A is correct as it acknowledges the purpose of ice in reducing swelling. Choice C shows understanding of using ice as directed. Choice D indicates proper understanding of combining elevation with ice for swelling reduction.
Question 5 of 5
A patient in Russell traction with a Pearson attachment for a fracture of the tibia complains of intense pain at the fracture site. The nurse assesses a temperature of 102° F and increased swelling at the fracture site. Which complication do these findings suggest?
Correct Answer: A
Rationale: The correct answer is A: Osteomyelitis. The combination of intense pain, increased swelling, elevated temperature, and presence of traction indicates an infection in the bone, suggesting osteomyelitis. This serious complication requires prompt treatment with antibiotics. Incorrect choices: B: Fat embolism - This typically presents with respiratory distress, petechiae, and neurological changes, not with localized pain and swelling. C: Traction misalignment - This would cause a change in the alignment of the fracture but would not typically present with fever and localized signs of infection. D: Nonunion of the fracture - Nonunion is a failure of the bone to heal, which would not typically present with the acute signs of infection seen in this case.
