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 nurse is caring for a patient with peripheral vascular disease (PVD). The patient
complains of burning and tingling of the hands and feet and cannot tolerate touch of any
kind. Which of the following is the most likely explanation for these symptoms?
- A. Inadequate tissue perfusion leading to nerve damage.
- B. Fluid overload leading to compression of nerve tissue.
- C. Sensation distortion due to psychiatric disturbance.
- D. Inflammation of the skin on the hands and feet.
Correct Answer: A
Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of
inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the
extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest
pain often is exacerbated by poor cardiac output. The condition is often partially or fully
relieved by placing the extremity in a dependent position, so that perfusion is enhanced by
the effects of gravity.
A client is found unresponsive in his room by a nurse. The client is not breathing and does not have a pulse. After calling for help, what is the next action the nurse should take?
- A. Administer 2 ventilations
- B. Perform a head-tilt, chin lift to open the airway
- C. Begin chest compressions
- D. Perform a jaw thrust to open the airway
Correct Answer: C
Rationale: After finding an unresponsive client who is not breathing and has no pulse, the nurse's immediate action should be to call for help and start chest compressions. Chest compressions should be initiated at a rate of at least 100 per minute and a depth of at least 2 inches. Choice A, administering ventilations, is not the initial step as compressions take priority. Choice B, performing a head-tilt, chin lift, is also not the first step; chest compressions are crucial before airway management. Choice D, performing a jaw thrust, is typically used in cases of suspected cervical spine injury and is not the immediate action in this scenario.
A patient with a possible pulmonary embolism complains of chest pain and difficulty breathing. The nurse finds a heart rate of 142 beats/minute, blood pressure of 100/60 mmHg, and respirations of 42 breaths/minute. Which action should the nurse take first?
- A. Administer anticoagulant drug therapy.
- B. Notify the patient's healthcare provider.
- C. Prepare the patient for a spiral computed tomography (CT).
- D. Elevate the head of the bed to a semi-Fowler's position.
Correct Answer: D
Rationale: The patient presents with symptoms indicative of a pulmonary embolism (PE), such as chest pain, difficulty breathing, tachycardia, hypotension, and tachypnea. Elevating the head of the bed to a semi-Fowler's position is the priority to improve ventilation and gas exchange. This intervention should be initiated promptly to optimize oxygenation. Subsequent actions, such as notifying the healthcare provider, preparing for a spiral CT scan, and administering anticoagulant therapy, can follow after the patient's position is adjusted. The spiral CT scan is typically used to confirm the diagnosis of PE, and anticoagulant therapy is initiated upon confirmation of the diagnosis by the healthcare provider. Therefore, the immediate focus is on improving the patient's respiratory status by elevating the head of the bed.
The nurse prepares a patient with a left-sided pleural effusion for a thoracentesis. How should the nurse position the patient?
- A. Supine with the head of the bed elevated 30 degrees
- B. In a high-Fowler's position with the left arm extended
- C. On the right side with the left arm extended above the head
- D. Sitting upright with the arms supported on an overbed table
Correct Answer: D
Rationale: The correct position for a patient with a left-sided pleural effusion undergoing thoracentesis is sitting upright with the arms supported on an overbed table. This position helps increase lung expansion, allows fluid to collect at the lung bases, and expands the intercostal space making access to the pleural space easier. Placing the patient supine, in a high-Fowler's position, or on the right side with the left arm extended above the head could increase the work of breathing for the patient and complicate the thoracentesis procedure for the healthcare provider.
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.
