Immune System Exam Questions Questions
Question 1 of 5
Which medication is a uricosuric agent?
Correct Answer: A
Rationale: The correct answer is A: Probenecid. Probenecid is a uricosuric agent that works by increasing the excretion of uric acid in the urine, thereby reducing its levels in the blood. This helps in the treatment of gout and hyperuricemia. Allopurinol (B) and Febuxostat (C) are xanthine oxidase inhibitors that work by reducing the production of uric acid. Colchicine (D) is used to relieve gout flares by reducing inflammation and pain, but it is not a uricosuric agent.
Question 2 of 5
A client is being administered the first dose of belimumab for a systemic lupus erythematosus flare. What actions by the nurse are most appropriate? (Select one that does not apply)
Correct Answer: C
Rationale: The correct answer is C: Inform the client not to drive or sign legal papers for 24 hours. This is because belimumab can cause dizziness or drowsiness as a side effect, which may impair the client's ability to drive or make important decisions. A: Observing the client for at least 2 hours afterward is important for monitoring immediate reactions to the medication. B: Instructing the client about the monthly infusion schedule is important for treatment adherence but not directly related to the first dose administration. D: Ensuring emergency equipment is working and nearby is important for safety but not specific to the first dose administration.
Question 3 of 5
A patient being seen in an outpatient clinic has had a complete blood count done. The results indicate increased eosinophil count. This finding is highly suggestive of a/an:
Correct Answer: A
Rationale: The correct answer is A: Parasitic infestation. Eosinophils are white blood cells that are typically elevated in response to parasitic infections. Parasites trigger an immune response that involves an increase in eosinophils to help combat the infection. Bacterial infections (choice B) usually lead to an increase in neutrophils, while viral infections (choice C) typically result in an increase in lymphocytes. Fungal reactions (choice D) can cause an increase in eosinophils, but parasitic infestations are more commonly associated with this finding. In this case, the increased eosinophil count is highly suggestive of a parasitic infestation based on the patient's clinical presentation and laboratory results.
Question 4 of 5
The nurse prepares to give a bath and change the bed linens of a client with cutaneous Kaposi's sarcoma lesions. The lesions are open and draining a scant amount of serous fluid. Which would the nurse incorporate into the plan during the bathing of this client?
Correct Answer: B
Rationale: The correct answer is B (Wearing a gown and gloves). When dealing with open and draining lesions like those seen in cutaneous Kaposi's sarcoma, it is important for the nurse to wear a gown and gloves to protect themselves from exposure to the serous fluid. The gown provides an additional layer of protection for the nurse's clothing, while gloves prevent direct contact with the fluid. Wearing just gloves (choice A) may not provide enough protection for the nurse's clothing. Adding a mask (choice C) is unnecessary since the serous fluid is not airborne. Choice D is incorrect as changing the bed linens with just gloves does not provide sufficient protection for the nurse's clothing.
Question 5 of 5
The nurse is preparing a group of Cub Scouts for an overnight camping trip and instructs the Scouts about the methods to prevent Lyme disease. Which statement by one of the Scouts indicates a need for further instruction?
Correct Answer: C
Rationale: The correct answer is C because using insect repellents is actually recommended to prevent tick bites, not attract them. Ticks are repelled by certain chemicals in insect repellents, so using repellents can help reduce the risk of getting Lyme disease. Therefore, the Scout's statement about not using insect repellents shows a misunderstanding and indicates a need for further instruction. In contrast, choices A, B, and D are all correct preventive measures for Lyme disease. Wearing a hat, long-sleeved tops, long pants, closed shoes, and socks that can be pulled up over pants all help to minimize skin exposure to ticks and reduce the chances of getting bitten.
