A nurse in the rehabilitation unit is caring for an older adult patient who is in cardiac rehabilitation following an MI. The nurses plan of care calls for the patient to walk for 10 minutes 3 times a day. The patient questions the relationship between walking and heart function. How should the nurse best reply?
- A. The arteries in your legs constrict when you walk and allow the blood to move faster and with more pressure on the tissue.
- B. Walking increases your heart rate and blood pressure. Therefore your heart is under less stress.
- C. Walking helps your heart adjust to your new arteries and helps build your self-esteem.
- D. When you walk, the muscles in your legs contract and pump the blood in your veins back toward your heart, which allows more blood to return to your heart.
Correct Answer: D
Rationale: Veins, unlike arteries, are equipped with valves that allow blood to move against the force of gravity. The legs have one-way bicuspid valves that prevent blood from seeping backward as it moves forward by the muscles in our legs pressing on the veins as we walk and increasing venous return. Leg arteries do constrict when walking, which allows the blood to move faster and with more pressure on the tissue, but the greater concern is increasing the flow of venous blood to the heart. Walking increases, not decreases, the heart pumping ability, which increases heart rate and blood pressure and the hearts ability to manage stress. Walking does help the heart adjust to new arteries and may enhance self-esteem, but the patient had an MIthere are no new arteries.

The nurse is admitting a 32-year-old woman to the presurgical unit. The nurse learns during the admission assessment that the patient takes oral contraceptives. Consequently, the nurses postoperative plan of care should include what intervention?
- A. Early ambulation and leg exercises
- B. Cessation of the oral contraceptives until 3 weeks postoperative
- C. Doppler ultrasound of peripheral circulation twice daily
- D. Dependent positioning of the patients extremities when at rest
Correct Answer: A
Rationale: Oral contraceptive use increases blood coagulability; with bed rest, the patient may be at increased risk of developing deep vein thrombosis. Leg exercises and early ambulation are among the interventions that address this risk. Assessment of peripheral circulation is important, but Doppler ultrasound may not be necessary to obtain these data. Dependent positioning increases the risk of venous thromboembolism (VTE). Contraceptives are not normally discontinued to address the risk of VTE in the short term.
The nurse is taking a health history of a new patient. The patient reports experiencing pain in his left lower leg and foot when walking. This pain is relieved with rest. The nurse notes that the left lower leg is slightly edematous and is hairless. When planning this patients subsequent care, the nurse should most likely address what health problem?
- A. Coronary artery disease (CAD)
- B. Intermittent claudication
- C. Arterial embolus
- D. Raynauds disease
Correct Answer: B
Rationale: A muscular, cramp-type pain in the extremities consistently reproduced with the same degree of exercise or activity and relieved by rest is experienced by patients with peripheral arterial insufficiency. Referred to as intermittent claudication, this pain is caused by the inability of the arterial system to provide adequate blood flow to the tissues in the face of increased demands for nutrients and oxygen during exercise. The nurse would not suspect the patient has CAD, arterial embolus, or Raynauds disease; none of these health problems produce this cluster of signs and symptoms.
The clinic nurse is caring for a 57-year-old client who reports experiencing leg pain whenever she walks several blocks. The patient has type 1 diabetes and has smoked a pack of cigarettes every day for the past 40 years. The physician diagnoses intermittent claudication. The nurse should provide what instruction about long-term care to the client?
- A. Be sure to practice meticulous foot care.
- B. Consider cutting down on your smoking.
- C. Reduce your activity level to accommodate your limitations.
- D. Try to make sure you eat enough protein.
Correct Answer: A
Rationale: The patient with peripheral vascular disease or diabetes should receive education or reinforcement about skin and foot care. Intermittent claudication and other chronic peripheral vascular diseases reduce oxygenation to the feet, making them susceptible to injury and poor healing; therefore, meticulous foot care is essential. The patient should stop smokingnot just cut downbecause nicotine is a vasoconstrictor. Daily walking benefits the patient with intermittent claudication. Increased protein intake will not alleviate the patients symptoms.
The nurse is providing care for a patient who has just been diagnosed with peripheral arterial occlusive disease (PAD). What assessment finding is most consistent with this diagnosis?
- A. Numbness and tingling in the distal extremities
- B. Unequal peripheral pulses between extremities
- C. Visible clubbing of the fingers and toes
- D. Reddened extremities with muscle atrophy
Correct Answer: B
Rationale: PAD assessment may manifest as unequal pulses between extremities, with the affected leg cooler and paler than the unaffected leg. Intermittent claudication is far more common than sensations of numbness and tingling. Clubbing and muscle atrophy are not associated with PAD.
The nurse has performed a thorough nursing assessment of the care of a patient with chronic leg ulcers. The nurses assessment should include which of the following components?
- A. Location and type of pain
- B. Apical heart rate
- C. Bilateral comparison of peripheral pulses
- D. Comparison of temperature in the patients legs
- E. Identification of mobility limitations
Correct Answer: A,C,D,E
Rationale: A careful nursing history and assessment are important. The extent and type of pain are carefully assessed, as are the appearance and temperature of the skin of both legs. The quality of all peripheral pulses is assessed, and the pulses in both legs are compared. Any limitation of mobility and activity that results from vascular insufficiency is identified. Not likely is there any direct indication for assessment of apical heart rate, although peripheral pulses must be assessed.
