Respiratory System NCLEX Questions

Extract:

Question 1 of 5

The charge nurse receives morning laboratory and respiratory data on the clients. Which data requires immediate intervention?

Correct Answer: B

Rationale: SpO2 89% post

Question 2 of 5

Which statement below is incorrect about a deep vein thrombosis (DVT)?

A. Veins that are most susceptible to a deep vein thrombosis are the peroneal, posterior tibial, popliteal and superficial femoral. B. DVTs tend to mostly occur in the lower extremities but can occur in the upper extremities too. C. A deep vein thrombosis in the lower extremity has a low probability of becoming a pulmonary embolism. D. A DVT is a type of venous thromboembolism (VTE), which is a blood clot that starts in the vein.

Correct Answer: C

Rationale: This option is INCORRECT. All the other statements are true about a DVT. Option C is wrong because it should say: 'A deep vein thrombosis in the lower extremity has a HIGH (not low) probability of becoming a pulmonary embolism.'

Question 3 of 5

The employee health nurse is administering tuberculin skin testing to employees who have possibly been exposed to a client with active tuberculosis (Tb). Which statement indicates the need for radiological evaluation instead of skin testing?

A. The client's first skin test indicates a purple flat area at the site of injection. B. The client's second skin test indicates a red area measuring four (4) mm. C. The client's previous skin test was read as positive. D. The client has never shown a reaction to the tuberculin medication.

Correct Answer: C

Rationale: A prior positive TB skin test (
C) indicates exposure, requiring CXR to assess active disease, not repeat skin testing. Purple area (
A) is normal, 4 mm (
B) is negative, and no reaction (
D) warrants testing.

Question 4 of 5

Which nursing assessment data support that the client has experienced a pulmonary embolism?

A. Calf pain with dorsiflexion of the foot. B. Sudden onset of chest pain and dyspnea. C. Left-sided chest pain and diaphoresis. D. Bilateral crackles and low-grade fever.

Correct Answer: B

Rationale: Sudden chest pain and dyspnea (
B) are classic PE symptoms from hypoxia. Calf pain (
A) suggests DVT, left-sided pain (
C) suggests MI, and crackles/fever (
D) suggest pneumonia.

Question 5 of 5

A 25 year-old female patient with pneumonia is prescribed Doxycycline. What question is important to ask the patient prior to administration of this medication?

A. Do you take birth control pills?' B. Are you allergic to Penicillin?' C. Are you allergic to eggs?' D. Do you have a history of diabetes?'

Correct Answer: A

Rationale: Doxycycline can reduce the effectiveness of oral contraceptives, so asking about birth control use is critical. Penicillin allergy is unrelated, egg allergy is relevant for vaccines, and diabetes is not a primary concern.
