Nurse Oliver is working in a out patient clinic. He has been alerted that there is an outbreak of tuberculosis (TB). Which of the following clients entering the clinic today most likely to have TB?

Correct Answer: C

Rationale: The correct answer is C, the 43-year-old homeless man with a history of alcoholism. This choice is most likely to have TB due to the increased risk factors associated with homelessness, alcoholism, and compromised immune system. Homeless populations are at higher risk for TB due to crowded living conditions and poor access to healthcare. Alcoholism can weaken the immune system, making individuals more susceptible to TB infection. The other choices do not have the same level of risk factors for TB compared to the homeless man with alcoholism. A, the 16-year-old high school student, is less likely to have TB as younger age groups typically have lower rates of TB. B, the 33-year-old day-care worker, may have some exposure risk, but it is not as high as the homeless man with alcoholism. D, the 54-year-old businessman, does not have the same risk factors for TB as the homeless man with alcoholism.

Correct Answer: D

Rationale: The correct answer is D because after receiving a subarachnoid block, the client should remain supine for the specified time to prevent complications like a sudden drop in blood pressure. This position helps maintain proper blood flow to the brain and spinal cord. A is incorrect because maintaining hydration is important postoperatively. B is incorrect as there is no specific reason to avoid milk products. C is incorrect as blood in urine is not a common complication of a subarachnoid block and would not be the most important instruction at this time.

Correct Answer: C

Rationale: The correct answer is C: Deep vein thrombosis (DVT) due to immobility of the ipsilateral side. After a stroke, immobility can lead to blood pooling in the deep veins, increasing the risk of DVT. This can cause swelling in the affected limb. Choices A and B do not directly relate to swelling post-stroke. Choice D is not relevant to the situation described. Therefore, the correct choice is C due to the increased risk of DVT from immobility post-stroke.

Correct Answer: B

Rationale: The correct answer is B: Pallor, tachycardia, and a sore tongue. In pernicious anemia, the body lacks intrinsic factor needed for vitamin B12 absorption, leading to megaloblastic anemia. Pallor is a common symptom due to decreased red blood cells. Tachycardia occurs as the heart compensates for decreased oxygen-carrying capacity. A sore tongue, known as glossitis, is a classic sign of B12 deficiency. Choices A, C, and D do not align with typical manifestations of pernicious anemia.
