NCLEX Questions Respiratory

Extract:

Question 1 of 5

A patient is taking Streptomycin. Which finding below requires the nurse to notify the physician?

Correct Answer: C

Rationale: Streptomycin can cause ototoxicity, leading to symptoms like ringing in the ears (tinnitus). This requires immediate physician notification to prevent further hearing damage.

Question 2 of 5

Which statement made by the client indicates the nurse's discharge teaching is effective for the client diagnosed with COPD?

A. I need to get an influenza vaccine each year, even when there is a shortage. B. I need to get a vaccine for pneumonia each year with my influenza shot. C. If I reduce my cigarettes to six (6) a day, I won't have difficulty breathing. D. I need to restrict my drinking liquids to keep from having so much phlegm.

Correct Answer: A

Rationale: Annual flu vaccines (
A) reduce COPD exacerbation risk, even in shortages. Pneumonia vaccines (
B) are not yearly, smoking reduction (
C) is insufficient, and fluid restriction (
D) is incorrect.

Question 3 of 5

The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client diagnosed with a pulmonary embolus. Which data would cause the nurse to question administering the medication?

A. The client's partial thromboplastin time (PTT) is 38. B. The client's international normalized ratio (INR) is 5. C. The client's prothrombin time (PT) is 22. D. The client's erythrocyte sedimentation rate (ESR) is 10.

Correct Answer: B

Rationale: An INR of 5 (
B) is above the therapeutic range (2–3 for pulmonary embolus), indicating excessive anticoagulation and bleeding risk, so warfarin should be questioned. PTT (
A) is for heparin, not warfarin. PT (
C) alone is not standardized. ESR (
D) is irrelevant to anticoagulation.

Question 4 of 5

The nurse performs postural drainage on the client. Which nursing intervention is most beneficial to loosen secretions?

A. Telling the client to take deep breaths B. Striking the back with a cupped hand C. Applying pressure below the diaphragm D. Placing the client in a sitting position

Correct Answer: B

Rationale: Striking the back with a cupped hand (percussion) helps loosen secretions during postural drainage.

Question 5 of 5

Which diagnostic test should the nurse anticipate the health-care provider ordering to rule out the diagnosis of asthma in clients diagnosed with chronic obstructive pulmonary disease (COPD)?

A. A bronchoscopy. B. An immunoglobulin E. C. An arterial blood gas. D. A bronchodilator reversibility test.

Correct Answer: D

Rationale: A bronchodilator reversibility test differentiates asthma from COPD by assessing whether airway obstruction is reversible. In asthma, lung function (e.g., FEV1) improves significantly post-bronchodilator, while COPD shows minimal improvement. Bronchoscopy (
A) is invasive and not specific for this differentiation. Immunoglobulin E (
B) is relevant for allergies, not distinguishing asthma from COPD. Arterial blood gases (
C) assess oxygenation but do not differentiate these conditions.
