Multiple Choice Questions on Immune System Questions
Question 1 of 5
Reinforcing teaching with a client who has a diagnosis of hep A- understanding of teaching?
Correct Answer: B
Rationale: The correct answer is B because Hepatitis A is transmitted through the fecal-oral route by consuming contaminated food or water. Stopping the consumption of raw clams, which could potentially be contaminated, is an appropriate precaution. A is incorrect as it mentions Hepatitis B transmission through shared needles and unclean tattoo equipment, which is not relevant to Hepatitis A. C is incorrect as avoiding all physical contact is an extreme measure and unnecessary for preventing Hepatitis A transmission. D is incorrect as boiling drinking water for 10 minutes is not a specific preventive measure for Hepatitis A, which is mainly spread through contaminated food and water.
Question 2 of 5
Teaching with AP about standard precaution when caring for a client who has vancomycin resistant enterococcus of the urine- PPE should nurse recommend the AP to use when caring for the client?
Correct Answer: B
Rationale: The correct answer is B because wearing don clean gloves provides a barrier to prevent direct contact with bodily fluids contaminated with VRE. Gloves are essential in preventing the transmission of bacteria during care. Choice A is incorrect because goggles are not specifically necessary for VRE of the urine unless there is a risk of splashing or spraying of bodily fluids towards the eyes. Choice C is unnecessary unless there is a high risk of exposure to splashes or sprays to the face. Choice D is not necessary for all interactions unless there is a risk of contamination of clothing with bodily fluids.
Question 3 of 5
The nurse is reviewing blood results for an HIV patient. The nurse knows that the patient is at stage 2 when the CD4 count is at what level?
Correct Answer: D
Rationale: The correct answer is D (250 cells/μL). At stage 2 of HIV infection, the CD4 count typically ranges from 200 to 499 cells/μL. This means a CD4 count of 250 cells/μL falls within this range, indicating the patient is at stage 2. Choice A (534 cells/μL) is incorrect as it is above the range for stage 2. Choice B (601 cells/μL) is also incorrect as it is above the range for stage 2. Choice C (100 cells/μL) is incorrect as it falls below the range for stage 2. Thus, the correct answer is D based on the CD4 count range associated with stage 2 of HIV infection.
Question 4 of 5
In acute lymphatic leukaemia:
Correct Answer: A
Rationale: The correct answer is A because acute lymphatic leukaemia specifically involves the overproduction of abnormal lymphocytes in the bone marrow. This leads to a decrease in normal blood cell production. Choice B is incorrect because leukaemia primarily affects the production of specific types of white blood cells, not all types. Choice C is incorrect because acute lymphatic leukaemia involves abnormal lymphocytes, not specifically B lymphocytes. Choice D is incorrect because not all types of white blood cells are affected in acute lymphatic leukaemia.
Question 5 of 5
People with irritable bowel syndrome for longer than 10 years:
Correct Answer: D
Rationale: The correct answer is D: None of the above. People with irritable bowel syndrome do not necessarily need a hemicolectomy, as it is usually not a treatment option for IBS. There is no direct link between IBS and cancer, so the statement in option B is incorrect. IBS does not affect fertility, so option C is also incorrect. Therefore, the most appropriate answer is D as none of the statements provided are true for individuals with irritable bowel syndrome.
