A conscious patient with dyspnea is anxious and using accessory muscles. Which initial nursing response is most appropriate while arranging care?

  1. A

  2. B

    Place the patient flat and leave to collect supplies.

  3. C

    Ask the patient to hold their breath to slow their breathing.

A patient with asthma is struggling to speak and using accessory muscles. Wheezing heard earlier is now barely audible, and the patient appears drowsy. What is the priority response?

  1. A

    Encourage coughing and reassess in 30 minutes.

  2. B

    Treat the change as life-threatening deterioration, activate emergency support, and provide immediate care within protocol.

  3. C

    Offer oral fluids to loosen secretions.

  4. D

    Ask the patient to lie flat to conserve energy.

A patient with COPD has a prescribed oxygen target of 88–92%. Their SpO₂ is 86% on the current oxygen setting, and they are more breathless than earlier. What should the nurse do first?

  1. A

    Remove oxygen because supplemental oxygen is unsafe for anyone with COPD.

  2. B

    Assess breathing and equipment, promptly escalate the worsening hypoxemia, and adjust oxygen according to the prescription or protocol.

  3. C

    Turn oxygen off and wait for an arterial blood gas result.

  4. D

    Document the reading and wait until the next routine observation.

An older adult admitted with pneumonia becomes newly confused, breathes rapidly, and has a falling SpO₂. What is the best priority action?

  1. A

    Reorient the patient and wait to see whether the confusion resolves.

  2. B

    Promptly reassess respiratory status and vital signs, support oxygenation according to protocol, and escalate the acute change.

  3. C

    Encourage the patient to walk to improve lung expansion.

  4. D

    Offer food and fluids before reassessing.

A patient who recently had surgery suddenly develops shortness of breath, pleuritic chest pain, tachycardia, and light-headedness. What is the priority nursing action?

  1. A

    Assist the patient to walk to assess exercise tolerance.

  2. B

    Activate urgent medical evaluation, remain with the patient, and assess airway, breathing, circulation, and vital signs.

  3. C

    Give an oral fluid bolus and reassess in an hour.

  4. D

    Assume the symptoms are pneumonia because the patient is coughing.

A patient’s SpO₂ reading does not match their appearance or reported symptoms. Which actions are appropriate? Select all that apply.

  1. A

    Check probe position and signal; reduce motion and address a cold or poorly perfused hand if possible.

  2. B

    Consider skin pigmentation and nail polish when interpreting the reading.

  3. C

    Rely on the pulse-oximeter value alone if it is within the device’s displayed range.

  4. D

    Reassess the patient and consider further clinical evaluation if concern remains.

After an intervention for dyspnea, which findings together provide the most useful picture of the patient’s response? Select all that apply.

  1. A

    Respiratory rate and effort, ability to speak, mental status, breath sounds, and vital signs.

  2. B

    The SpO₂ trend and the patient’s response to treatment.

  3. C

    SpO₂ alone, without other assessment findings.

  4. D

    Skin color alone.
