Adult Health II Respiratory NCLEX Questions Questions
Extract:
Question 1 of 5
When a client is diagnosed with aplastic anemia, the nurse should assess the client for changes in which of the following physiologic functions?
Correct Answer: A
Rationale: Aplastic anemia causes pancytopenia, including thrombocytopenia, which increases the risk of bleeding. The nurse should assess for bleeding tendencies, such as petechiae, bruising, or mucosal bleeding. Intake/output, sensation, and bowel function are not primarily affected.
Question 2 of 5
The nurse has just admitted a 35-year-old female client who has a serum vitamin B12 concentration of 800 pg/mL. Which of the following laboratory findings should cue the nurse to focus the client history assessment on specific drug or alcohol use?
Correct Answer: D
Rationale: A serum vitamin B12 level of 800 pg/mL is within the normal range (200–900 pg/mL), but a folate level of 1.5 ng/mL is low (normal: 2.7–17 ng/mL). Low folate levels can be associated with chronic alcohol use, as alcohol impairs folate absorption and metabolism. The nurse should assess the client's history for alcohol use, as this may contribute to the folate deficiency. The other lab values (bilirubin, creatinine, hemoglobin) are normal and do not suggest drug or alcohol use.
Question 3 of 5
The nurse is assessing a client's activity tolerance by having the client walk on a treadmill for 5 minutes. Which of the following indicates an abnormal response?
Correct Answer: B
Rationale: A decrease in respiratory rate after exercise is abnormal, as physical activity typically increases respiratory demand to meet oxygen needs. A pulse increase of 20 bpm, a slight rise in diastolic blood pressure, and a near-return to resting pulse after 3 minutes are normal responses to moderate exercise.
Question 4 of 5
Nursing responsibilities for the client with a patient-controlled analgesia (PCA) system should include:
Correct Answer: B
Rationale: Documenting the client's response to PCA is a key nursing responsibility to monitor efficacy and safety. Reassuring complete relief, instructing to press repeatedly, or titrating to pain-free status may be unrealistic or unsafe.
Question 5 of 5
College freshman are participating in a study abroad program. When teaching them about hepatitis B, the nurse should instruct the students on:
Correct Answer: D
Rationale: Hepatitis B is transmitted through blood and body fluids, so safe sexual practices (
D) are critical for prevention. Water sanitation (
A) is relevant for hepatitis A, single rooms (
B) are unnecessary, and while vaccination (
C) is important, the question focuses on behavioral instruction.
