ATI Perfusion Quizlet

Correct Answer: C

Rationale: The correct answer is C: 'Avoid exposure to crowds when possible.' This instruction is crucial in discharge teaching for a patient admitted with a sickle cell crisis because exposure to crowds increases the risk of infection, which is the most common cause of sickle cell crisis. Choices A, B, and D are incorrect. Taking a daily multivitamin with iron (Choice A) may be beneficial for some individuals but is not specifically related to managing sickle cell crisis. Limiting fluids to 2 to 3 quarts per day (Choice B) is not typically recommended for patients with sickle cell crisis, as adequate hydration is important. Drinking only two caffeinated beverages daily (Choice D) is not a priority instruction in managing sickle cell crisis.

Correct Answer: B

Rationale: In severe hemolytic anemia, the priority nursing intervention is to alternate periods of rest and activity. This approach helps to balance activity levels to prevent excessive fatigue while promoting mobility and preventing complications such as muscle weakness or deconditioning. Providing a diet high in vitamin K (choice A) is not directly related to managing hemolytic anemia. Teaching the patient how to avoid injury (choice C) is important but may not be the immediate priority. Placing the patient on protective isolation (choice D) is not indicated for hemolytic anemia, as it is not a contagious condition.

Correct Answer: A

Rationale: The correct action to include in the plan of care for a thrombocytopenic patient is to avoid intramuscular injections. Thrombocytopenia is a condition characterized by a decreased number of platelets, which are essential for blood clotting. Intramuscular injections can pose a risk of bleeding in patients with low platelet counts. Encouraging increased oral fluids (choice B) is beneficial for hydration but does not directly address the risk of bleeding associated with thrombocytopenia. Checking temperature every 4 hours (choice C) is important for monitoring infection but does not specifically address the risk of bleeding. Increasing intake of iron-rich foods (choice D) is more related to addressing anemia, not the primary concern of bleeding in thrombocytopenia.

Correct Answer: B

Rationale: The correct answer is B: 'Check temperature every 4 hours.' Neutropenic patients have a weakened immune system due to low levels of neutrophils, which are a type of white blood cell that helps fight infections. Monitoring the patient's temperature every 4 hours is crucial because the earliest sign of infection in a neutropenic patient is often a fever. This allows for early detection of any potential infections. Choices A, C, and D are incorrect because avoiding intramuscular injections, omitting fruits or vegetables from the diet, and placing a 'No Visitors' sign on the door are not specific actions directly related to managing neutropenia or monitoring for signs of infection.

Correct Answer: A

Rationale: In the case of a patient with pancytopenia of unknown origin, a bone marrow biopsy is usually indicated to determine the cause. A bone marrow biopsy is a minor surgical procedure that requires the patient or guardian to sign a surgical consent form. Abdominal ultrasound (Choice B) is not typically used to diagnose pancytopenia. A Complete Blood Count (CBC) (Choice C) is a routine blood test and does not require a specific consent form. Activated Partial Thromboplastin Time (aPTT) (Choice D) is a coagulation test and not typically performed to diagnose pancytopenia.
