Nursing Elites

1. The nurse is assessing a client with pneumonia who is receiving oxygen therapy. Which finding indicates that the therapy is effective?

• A. The client's respiratory rate is 20 breaths per minute.
• B. The client's arterial blood gases show a pH of 7.35.
• C. The client's oxygen saturation is 92%.
• D. The client's breath sounds are clear.

Correct answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

2. A client with a history of asthma is admitted with shortness of breath. Which assessment finding requires immediate intervention?

• A. Expiratory wheezes.
• B. Increased respiratory rate.
• C. Absence of breath sounds.
• D. Frequent coughing.

Correct answer: C

Rationale: The correct answer is C: Absence of breath sounds. This finding is concerning in a client with asthma as it may indicate a severe asthma exacerbation, airway obstruction, or pneumothorax, all of which require immediate intervention. Absence of breath sounds suggests a lack of airflow in the lungs, which is a critical sign that should prompt immediate action. Expiratory wheezes (choice A) are common in asthma and may not warrant immediate intervention unless severe. An increased respiratory rate (choice B) is expected in a client with asthma experiencing shortness of breath, but it does not indicate an immediate threat to the airway. Frequent coughing (choice D) is a common symptom in asthma exacerbations but does not signify an immediate need for intervention as it can be managed with appropriate asthma treatments.

3. Which bioterrorism agent is at high risk for use as a potential biological weapon that is readily transmitted by several portals of entry?

• A. anthrax
• B. smallpox
• C. botulism
• D. tularemia

Correct answer: A

Rationale: Anthrax is the correct answer. Anthrax spores can be transmitted through inhalation, ingestion, or skin contact, making it a high-risk agent for bioterrorism. Smallpox, botulism, and tularemia are also potential bioterrorism agents, but they do not have the same versatility in terms of multiple portals of entry, unlike anthrax.

4. A client who is receiving intravenous heparin therapy has an activated partial thromboplastin time (aPTT) of 90 seconds. Which action should the nurse take?

• A. Continue the heparin infusion as prescribed.
• B. Decrease the heparin infusion rate.
• C. Increase the heparin infusion rate.
• D. Stop the heparin infusion and notify the healthcare provider.

Correct answer: D

Rationale: An aPTT of 90 seconds is significantly elevated, indicating a high risk of bleeding due to excessive anticoagulation. In this case, the heparin infusion should be stopped immediately to prevent further anticoagulation and an increased bleeding risk. Notifying the healthcare provider is essential to discuss alternative anticoagulation strategies or interventions. Continuing heparin therapy without action could lead to severe bleeding complications. Decreasing or increasing the heparin infusion rate would exacerbate the risk of bleeding, making options A, B, and C incorrect.

5. A client with a history of asthma is admitted with shortness of breath. Which finding requires immediate intervention?

• A. Increased respiratory rate.
• B. Absence of breath sounds.
• C. Expiratory wheezes.
• D. Productive cough with green sputum.

Correct answer: B

Rationale: The correct answer is B: Absence of breath sounds. This finding can indicate a pneumothorax or severe asthma exacerbation, both of which require immediate intervention to ensure adequate ventilation and prevent further complications. Increased respiratory rate (choice A) is common in asthma exacerbations but may not always necessitate immediate intervention. Expiratory wheezes (choice C) are typical in asthma and may not always indicate a critical condition. A productive cough with green sputum (choice D) suggests a possible respiratory infection but does not warrant immediate intervention as much as the absence of breath sounds.
