ATI Perfusion Quizlet

Correct Answer: A

Rationale: The correct answer is A. A 2-cm nontender supraclavicular node is of most concern because enlarged and nontender nodes in this area are highly suggestive of malignancies such as lymphoma. Choice B is less concerning as a 1-cm mobile and nontender axillary node is usually benign. Choice C, an inability to palpate any superficial lymph nodes, could be due to factors like obesity or edema, but it is not necessarily a cause for immediate concern. Choice D, firm inguinal nodes in a patient with an infected foot, may indicate a local reaction to infection rather than a systemic issue related to malignancy.

Correct Answer: B

Rationale: The patient's young age and the presence of a nontender lump in the axilla raise concerns for possible lymphoma, which requires prompt evaluation and treatment. This patient should be seen first to rule out any serious underlying condition. Choice A is less urgent as yellowish eyes in sickle cell anemia may be due to jaundice but not necessarily an acute issue. Choice C, a 50-year-old with chronic fatigue related to early-stage chronic lymphocytic leukemia, is a known condition that can be managed on a routine basis. Choice D, a 19-year-old with hemophilia wanting to self-administer factor VII replacement, is important but less urgent compared to the potential lymphoma presentation in choice B.

Correct Answer: B

Rationale: The correct answer is B: Potential complication: infection. Patients with idiopathic aplastic anemia have pancytopenia, which puts them at a high risk for infections due to decreased production of all blood cells (red blood cells, white blood cells, and platelets). Infection is a significant concern in these patients. Choices A, C, and D are incorrect because seizures, neurogenic shock, and pulmonary edema are not typically associated with idiopathic aplastic anemia. While seizures can occur in some conditions that affect the brain, neurogenic shock is related to spinal cord injury, and pulmonary edema is more commonly seen in conditions like heart failure.

Correct Answer: C

Rationale: The correct answer is C. Pernicious anemia is a condition where the body can't absorb enough vitamin B12. Treatment usually involves lifelong replacement of vitamin B12. In this case, the patient understanding the disorder is correctly demonstrated by choosing nasal spray or injections of vitamin B12 for replacement therapy. Choices A, B, and D are incorrect because increasing red meat/liver intake, stopping wine consumption, or taking a proton pump inhibitor like omeprazole do not address the primary issue of vitamin B12 absorption in pernicious anemia.

Correct Answer: B

Rationale: Choice B is the correct answer because the scenario describes a 50-year-old with early-stage chronic lymphocytic leukemia who presents with chronic fatigue. Chronic lymphocytic leukemia commonly presents with symptoms like fatigue, weight loss, and enlarged lymph nodes. The other choices are less likely as they do not match the clinical presentation described in the scenario. Choice A describes a 23-year-old with a nontender lump in the axilla, which is more suggestive of a benign condition like a lipoma. Choice C describes a 19-year-old with hemophilia who wants to learn to self-administer factor VII replacement, which is unrelated to the symptoms of chronic lymphocytic leukemia. Choice D repeats the scenario, which is not relevant in selecting the appropriate answer.
