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 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.
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.
A 49-year-old patient with multiple sclerosis (MS) is to begin treatment with glatiramer acetate (Copaxone). Which information will the nurse include in patient teaching?
- A. Recommendation to drink at least 4 L of fluid daily
- B. Need to avoid driving or operating heavy machinery
- C. How to draw up and administer injections of the medication
- D. Use of contraceptive methods other than oral contraceptives
Correct Answer: C
Rationale: When initiating treatment with glatiramer acetate (Copaxone), patient education should focus on teaching the patient how to draw up and administer injections of the medication. Copaxone is administered via self-injection, hence understanding the correct technique is crucial for successful treatment. Recommendations regarding fluid intake or the need to avoid driving heavy machinery are not directly related to glatiramer acetate therapy. Additionally, while discussing contraceptive methods may be important, the use of oral contraceptives does not specifically contraindicate the use of glatiramer acetate.
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 who has a history of chronic obstructive pulmonary disease (COPD) was hospitalized for increasing shortness of breath and chronic hypoxemia (SaO2 levels of 89% to 90%). In planning for discharge, which action by the nurse will be most effective in improving compliance with discharge teaching?
- A. Start giving the patient discharge teaching on the day of discharge
- B. Have the patient repeat the instructions immediately after teaching
- C. Accomplish the patient teaching just before the scheduled discharge
- D. Arrange for the patient's caregiver to be present during the teaching
Correct Answer: D
Rationale: Hypoxemia interferes with the patient's ability to learn and retain information, so having the patient's caregiver present will increase the likelihood that discharge instructions will be followed. Having the patient repeat the instructions will indicate that the information is understood at the time, but it does not guarantee retention of the information. Giving discharge instructions just before discharge is not ideal as the patient is likely to be distracted and anxious at that time. Teaching the patient about discharge on the day of admission is not recommended because the patient may be more hypoxemic and anxious than usual, making it difficult for them to absorb and retain the information effectively. Therefore, arranging for the patient's caregiver to be present during the teaching session is the best option to ensure proper compliance and understanding of the discharge instructions.
