Assigning a patient to a float nurse from PACU. Which patient is best?

Correct Answer: C

Rationale: The correct answer is C because the patient post-colonoscopy with chronic GI bleeding requires close monitoring and immediate intervention if any complications arise. The float nurse from PACU is experienced in handling post-operative patients and can provide appropriate care for this patient's needs. Choice A is incorrect because a patient with thalassemia major receiving deferoxamine does not require immediate post-operative care. Choice B is incorrect as the patient with multiple myeloma needing discharge teaching can be managed by a regular floor nurse. Choice D is incorrect as the patient with pernicious anemia does not have urgent post-operative care needs.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin 7.1 g/dL. In ITP, low platelet count is common but does not typically require immediate reporting unless there are signs of significant bleeding. Hemoglobin of 7.1 g/dL indicates severe anemia, which requires prompt evaluation to assess the need for transfusion and determine the underlying cause. Increased eosinophils (A) are not typically concerning in ITP. Platelet count of 40,000/mm³ (C) is expected in ITP. Elevated reticulocyte count (D) may indicate compensatory response to anemia but does not warrant immediate reporting.

Correct Answer: C

Rationale: The correct answer is C because bleeding time evaluates platelet function in vivo by measuring the time it takes for a small, standardized skin incision to stop bleeding. This test directly assesses the primary hemostasis process mediated by platelets. Choice A is incorrect because bleeding time can be influenced by various factors, making it less reliable and reproducible. Choice B is incorrect because bleeding time is typically evaluated using a stopwatch, not an optical densitometer. Choice D is incorrect because bleeding time is not a commonly ordered test due to its limitations and variability in results.

Correct Answer: A

Rationale: The correct answer is A: Thrombosis. Thrombotic thrombocytopenic purpura (TTP) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and neurological deficits. Thrombosis is not a typical feature of TTP. In TTP, platelet aggregation leads to microthrombi formation, causing microangiopathic hemolytic anemia, thrombocytopenia, and neurological symptoms. Thrombosis, on the other hand, is more commonly associated with conditions such as deep vein thrombosis or pulmonary embolism. Therefore, choice A is not associated with TTP, making it the correct answer. Choices B, C, and D are incorrect as they are all features commonly seen in TTP.

Correct Answer: A

Rationale: Neutrophilia is the correct answer for chronic bacterial infection. Neutrophils are the first responders to bacterial infections, leading to an increase in their count. Basophils are involved in allergic reactions, not bacterial infections. Lymphocytosis is seen in viral infections. Eosinophilia is associated with parasitic infections and allergic responses.
