Which assessment finding should the nurse caring for a patient with thrombocytopenia communicate immediately to the healthcare provider?

Correct Answer: B

Rationale: The correct answer is B. Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. While a low platelet count (choice A) is concerning in thrombocytopenia, it does not require immediate communication unless accompanied by active bleeding or other critical symptoms. Purpura on the oral mucosa (choice C) and large bruises on the patient's back (choice D) are important findings in thrombocytopenia but do not indicate an immediate life-threatening situation like a possible cerebral hemorrhage.

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: A

Rationale: The correct answer is to check all stools for occult blood. With a platelet count of 18,000/µL, 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: D

Rationale: The patient's symptoms, back pain, and difficulty breathing after the transfusion indicate a possible acute hemolytic reaction, a severe transfusion reaction. The priority action in this situation is to discontinue the transfusion immediately to prevent further complications. Infusing normal saline helps maintain the patient's intravascular volume and prevent renal damage. Administering oxygen or obtaining a urine specimen is not the most urgent action and could delay essential treatment. Notifying the healthcare provider is important but should come after ensuring the patient's safety by stopping the blood transfusion.

Correct Answer: C

Rationale: The correct answer is C because administering subcutaneous medications falls within the education and scope of practice of an LPN/LVN. Assessing the patient for signs and symptoms of infection, teaching the patient, and developing a discharge plan are tasks that require an RN level of education and scope of practice. LPN/LVNs can assist in patient care, but tasks that involve assessment, teaching, and care planning are typically the responsibility of an RN.

Correct Answer: A

Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/µL is not significantly low to warrant a platelet transfusion without active bleeding. Consulting with the healthcare provider is essential before giving the transfusion to ensure the appropriateness of the treatment. Choices B, C, and D are not directly related to the need for consulting before a platelet transfusion. Petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and may not necessarily contraindicate a platelet transfusion at this platelet count.

Correct Answer: B

Rationale: The correct answer is B: Heparin. An activated partial thromboplastin time (aPTT) level of 28 seconds indicates a prolonged time, which is associated with heparin administration. Heparin is an anticoagulant medication that affects the intrinsic pathway of the coagulation cascade, leading to an increased aPTT. Aspirin (choice A) affects platelet aggregation and does not directly impact aPTT. Warfarin (choice C) affects the extrinsic pathway of the coagulation cascade and is monitored using the international normalized ratio (INR), not aPTT. Erythropoietin (choice D) is not related to coagulation parameters.

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: 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.
