ATI Perfusion Quizlet

Correct Answer: A

Rationale: The correct answer is to check all stools for occult blood. With a platelet count of 18,000/�L, the patient is at a high risk of spontaneous bleeding. Checking stools for occult blood can help detect any internal bleeding early. Encouraging fluids and providing oral hygiene are important interventions in general, but in this case, monitoring for bleeding takes precedence. Checking the temperature every 4 hours is not directly related to the patient's current condition and platelet count.

Correct Answer: B

Rationale: The correct answer is B: "Do you have any history of lung disease?" The elevated hemoglobin and hematocrit levels suggest polycythemia, which can be seen in conditions like chronic obstructive pulmonary disease (COPD). Option A is less relevant as weight loss is not typically associated with these blood count findings. Option C is more indicative of gastrointestinal bleeding rather than a respiratory issue. Option D focuses on dietary factors, which are less likely to cause such significant elevations in hemoglobin and hematocrit levels as seen in this case.

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: C

Rationale: The correct answer is C: Elevated temperature. When a CBC shows a 'shift to the left,' it indicates elevated levels of immature polymorphonuclear neutrophils (bands), which is a sign of infection. In response to the infection, the body increases its temperature as part of the immune response. Choices A, B, and D are incorrect because cool extremities, pallor and weakness, and low oxygen saturation are not typically associated with a 'shift to the left' in a CBC; they are more indicative of other conditions or issues.

Correct Answer: D

Rationale: Because infection is the most common cause of a sickle cell crisis, influenza, Haemophilus influenzae, pneumococcal pneumonia, and hepatitis immunizations should be administered.
