Adult Health II Respiratory NCLEX Questions Questions
Extract:
Question 1 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 2 of 5
When teaching a client to deep breathe effectively after a lobectomy, the nurse should instruct the client to do which of the following?
Correct Answer: C
Rationale: Effective deep breathing post-lobectomy involves relaxing abdominal muscles, taking a slow nasal breath, holding it 3–5 seconds, and exhaling to expand lungs. Contracting muscles or mouth breathing is less effective.
Question 3 of 5
A postoperative client is prescribed enoxaparin (Lovenox) 40 mg subcutaneous daily. Which laboratory value should the nurse monitor?
Correct Answer: A
Rationale: Enoxaparin can cause thrombocytopenia. Monitoring platelet count ensures early detection of this potential adverse effect.
Question 4 of 5
Which client position is contraindicated for a client with a spinal cord injury?
Correct Answer: A
Rationale: Supine with head flat is contraindicated as it may increase spinal pressure; other positions support alignment and safety.
Question 5 of 5
Which of the following clients is at greatest risk for Buerger's disease?
Correct Answer: A
Rationale: Buerger's disease (thromboangiitis obliterans) is strongly associated with heavy tobacco use, particularly in young males. A 29-year-old male with a 14-year smoking history is at greatest risk. Birth control pills, diabetes, and atherosclerosis are not primary risk factors for Buerger's disease.
