While caring for a patient with respiratory disease, the nurse observes that the patient's SpO2 drops from 93% to 88% while the patient is ambulating in the hallway. What is the priority action of the nurse?
- A. Notify the healthcare provider
- B. Document the response to exercise
- C. Administer the PRN supplemental O2
- D. Encourage the patient to pace activity
Correct Answer: C
Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.

Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:
- A. It results when oxygen demand is greater than oxygen supply.
- B. It is characterized by pain that often occurs during rest.
- C. It is a result of tissue hypoxia.
- D. It is characterized by cramping and weakness.
Correct Answer: D
Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.
A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?
- A. Intercostal retractions
- B. Kussmaul respirations
- C. Low oxygen saturation (SpO2)
- D. Decreased venous O2 pressure
Correct Answer: B
Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.
A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?
- A. Blood pressure (BP) is less than 140/90 mm Hg.
- B. Patient reports decreased exertional dyspnea
- C. Heart rate is between 60 and 100 beats/minute
- D. Patient's chest x-ray indicates clear lung fields
Correct Answer: B
Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.
A patient who has just been admitted with community-acquired pneumococcal pneumonia has a temperature of 101.6°F with a frequent cough and is complaining of severe pleuritic chest pain. Which prescribed medication should the nurse give first?
- A. Codeine
- B. Guaifenesin (Robitussin)
- C. Acetaminophen (Tylenol)
- D. Piperacillin/tazobactam (Zosyn)
Correct Answer: D
Rationale: The correct answer is Piperacillin/tazobactam (Zosyn). Early initiation of antibiotic therapy is crucial in cases of community-acquired pneumococcal pneumonia to reduce mortality. While providing symptomatic relief with medications like Codeine for cough, Guaifenesin for mucus clearance, and Acetaminophen for fever and pain is important, the priority should be to start antibiotic therapy to target the underlying infection. Piperacillin/tazobactam is an appropriate choice for treating severe community-acquired pneumonia caused by pneumococcal organisms.
A 64-year-old patient with amyotrophic lateral sclerosis (ALS) is hospitalized with pneumonia. Which nursing action will be included in the plan of care?
- A. Assist with active range of motion (ROM).
- B. Observe for agitation and paranoia.
- C. Give muscle relaxants as needed to reduce spasms.
- D. Use simple words and phrases to explain procedures.
Correct Answer: A
Rationale: In a patient with ALS, progressive muscle weakness is a significant issue. Assisting with active range of motion (ROM) exercises will help maintain muscle strength for as long as possible. Agitation and paranoia are not typically associated with ALS, making choice B incorrect. Giving muscle relaxants can further weaken muscles and depress respirations, worsening the condition, so choice C is inappropriate. Choice D is not directly related to the patient's physical condition and needs.
