ATI Hematologic System Test Questions
Question 1 of 5
The nurse is staying with a patient who has been started on a blood transfusion. Which assessment should the nurse perform during a blood product infusion to detect a reaction?
Correct Answer: A
Rationale: The correct answer is A: Vital signs. During a blood transfusion, the nurse should monitor the patient's vital signs regularly to detect any signs of a transfusion reaction, such as fever, chills, rash, or hypotension. Vital signs provide crucial information about the patient's overall condition and can help the nurse identify and respond promptly to any adverse reactions. Skin turgor (B), bowel sounds (C), and pupil reactivity (D) are not directly related to monitoring for transfusion reactions and are not sensitive indicators of an adverse reaction during a blood transfusion. Monitoring vital signs is essential for patient safety and early detection of any complications during the transfusion process.
Question 2 of 5
The nurse is reviewing the activated partial thromboplastin time for a patient receiving heparin. Which value indicates that the medication is within the therapeutic range?
Correct Answer: C
Rationale: The correct answer is C (1.5 to 2.0 times normal) because the therapeutic range for heparin is typically considered to be 1.5 to 2.5 times the normal value of activated partial thromboplastin time (aPTT). This range ensures adequate anticoagulation without increasing the risk of bleeding. Options A, B, and D are incorrect because they do not accurately reflect the therapeutic range for heparin. Option A provides a range in minutes, which is not a standard unit for aPTT measurement. Option B provides a range in seconds, which is too narrow for the therapeutic range of heparin. Option D provides a range in multiples of normal, but the upper limit of 3.0 times normal is higher than the typical upper limit of the therapeutic range for heparin.
Question 3 of 5
The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
Correct Answer: A
Rationale: Correct Answer: A: Do you take salicylates? Rationale: 1. Petechiae are tiny red or purple spots caused by bleeding under the skin. 2. Salicylates (like aspirin) can cause bleeding issues leading to petechiae. 3. Asking about salicylate use helps identify a potential cause for the petechiae. Summary of Incorrect Choices: B: Oral contraceptives are not typically associated with petechiae. C: Antiseizure drugs do not commonly cause petechiae. D: Antihypertensive drugs are not known to be a common cause of petechiae.
Question 4 of 5
When assessing a newly admitted patient, the nurse notes pallor of the skin and nail beds. The nurse should ensure that which laboratory test has been ordered?
Correct Answer: D
Rationale: The correct answer is D: Hemoglobin (Hgb) level. Pallor of the skin and nail beds indicates possible anemia, which is a decrease in red blood cells or hemoglobin. Checking the hemoglobin level will confirm if the patient is anemic. Platelet count (A) assesses for clotting ability, not anemia. Neutrophil count (B) and White blood cell count (C) are indicators of infection or inflammation, not anemia. Therefore, ensuring the hemoglobin level has been ordered is crucial for assessing the patient's pallor.
Question 5 of 5
A hospitalized client has a platelet count of 58,000/mm³. What action by the nurse is best?
Correct Answer: D
Rationale: The correct answer is D: Place the client on safety precautions. A platelet count of 58,000/mm³ indicates thrombocytopenia, increasing the risk of bleeding. Placing the client on safety precautions will minimize the risk of injury and bleeding. Encouraging high-protein foods (choice A) is not directly related to managing thrombocytopenia. Neutropenic precautions (choice B) are for clients with low neutrophil counts, not low platelet counts. Limiting visitors to healthy adults (choice C) is important for infection control, not addressing the risk of bleeding.
