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 patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?
- A. Ask the patient to lie down to complete a full physical assessment.
- B. Briefly ask specific questions about this episode of respiratory distress.
- C. Complete the admission database to check for allergies before treatment.
- D. Delay the physical assessment to first complete pulmonary function tests.
Correct Answer: B
Rationale: When a patient presents with acute shortness of breath, the initial assessment should focus on gathering specific information relevant to the current episode of respiratory distress. A comprehensive health history or full physical examination can be deferred until the acute distress has been addressed. Asking specific questions helps determine the cause of the distress and guides appropriate treatment. While checking for allergies is important, completing the entire admission database is not a priority during the initial assessment. Likewise, delaying the physical assessment for pulmonary function tests is not recommended as the immediate focus should be on addressing the acute respiratory distress before ordering further diagnostic tests or interventions.
A patient who has a right-sided chest tube following a thoracotomy has continuous bubbling in the suction-control chamber of the collection device. Which action by the nurse is most appropriate?
- A. Document the presence of continuous bubbling.
- B. Notify the surgeon of a possible pneumothorax.
- C. Take no further action with the collection device.
- D. Adjust the dial on the wall regulator to decrease suction.
Correct Answer: C
Rationale: Continuous bubbling in the suction-control chamber of the chest tube collection device is an expected finding and indicates that the suction control chamber is connected to suction. It does not necessarily indicate a large air leak, which would be detected in the water-seal chamber. There is no evidence to suggest a pneumothorax based solely on continuous bubbling in the suction-control chamber. Adjusting the suction level by changing the wall regulator setting is not indicated in this situation, as the amount of suction applied is primarily regulated by the water level in the water-seal chamber and not by the vacuum source. Therefore, the most appropriate action in this scenario is for the nurse to take no further action with the collection device.
A patient experiences a chest wall contusion as a result of being struck in the chest with a baseball bat. The emergency department nurse would be most concerned if which finding is observed during the initial assessment?
- A. Paradoxic chest movement
- B. Complaint of chest wall pain
- C. Heart rate of 110 beats/minute
- D. Large bruised area on the chest
Correct Answer: A
Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.
An alcoholic and homeless patient is diagnosed with active tuberculosis (TB). Which intervention by the nurse will be most effective in ensuring adherence with the treatment regimen?
- A. Arrange for a friend to administer the medication on schedule.
- B. Give the patient written instructions about how to take the medications.
- C. Teach the patient about the high risk for infecting others unless treatment is followed.
- D. Arrange for a daily noon meal at a community center where the drug will be administered
Correct Answer: D
Rationale: Directly observed therapy is the most effective means for ensuring compliance with the treatment regimen for a homeless patient with active tuberculosis. By arranging a daily noon meal at a community center where the drug will be administered, the nurse ensures that the patient is available to receive the medication and can directly observe the patient taking it. This method helps address the challenges faced by homeless individuals, such as lack of a stable living situation. The other options, such as having a friend administer the medication, giving written instructions, or educating about infecting others, may not be as effective in ensuring adherence, especially in the case of a homeless individual with alcoholism.
A patient who was admitted the previous day with pneumonia complains of a sharp pain of 7 (based on a 0 to 10 scale) whenever taking a deep breath. Which action will the nurse take next?
- A. Auscultate breath sounds.
- B. Administer PRN morphine.
- C. Have the patient cough forcefully.
- D. Notify the patient's healthcare provider.
Correct Answer: A
Rationale: The patient's complaint of sharp pain when taking a deep breath is concerning for pleurisy or pleural effusion. The nurse should auscultate breath sounds to assess for a pleural friction rub or decreased breath sounds, which could indicate these conditions. It is crucial to gather assessment data before initiating any pain medications. Asking the patient to cough forcefully may exacerbate the pain and should be avoided until further assessment. Contacting the healthcare provider should be based on the assessment findings; therefore, it is premature to notify the provider without conducting a thorough assessment first.
