Nokea
The nurse is assessing a woman who is pregnant at 27 weeks gestation. The patient is concerned about the recent emergence of varicose veins on the backs of her calves. What is the nurses best response?
- A. Facilitate a referral to a vascular surgeon.
- B. Assess the patients ankle-brachial index (ABI) and perform Doppler ultrasound testing.
- C. Encourage the patient to increase her activity level.
- D. Teach the patient that circulatory changes during pregnancy frequently cause varicose veins.
Correct Answer: D
Rationale: Pregnancy may cause varicosities because of hormonal effects related to decreased venous outflow, increased pressure by the gravid uterus, and increased blood volume. In most cases, no intervention or referral is necessary. This finding is not an indication for ABI assessment and increased activity will not likely resolve the problem.

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.
A nurse working in a long-term care facility is performing the admission assessment of a newly admitted, 85-year-old resident. During inspection of the residents feet, the nurse notes that she appears to have early evidence of gangrene on one of her great toes. The nurse knows that gangrene in the elderly is often the first sign of what?
- A. Chronic venous insufficiency
- B. Raynauds phenomenon
- C. VTE
- D. PAD
Correct Answer: D
Rationale: In elderly people, symptoms of PAD may be more pronounced than in younger people. In elderly patients who are inactive, gangrene may be the first sign of disease. Venous insufficiency does not normally manifest with gangrene. Similarly, VTE and Raynauds phenomenon do not cause the ischemia that underlies gangrene.
How should the nurse best position a patient who has leg ulcers that are venous in origin?
- A. Keep the patients legs flat and straight.
- B. Keep the patients knees bent to 45-degree angle and supported with pillows.
- C. Elevate the patients lower extremities.
- D. Dangle the patients legs over the side of the bed.
Correct Answer: C
Rationale: Positioning of the legs depends on whether the ulcer is of arterial or venous origin. With venous insufficiency, dependent edema can be avoided by elevating the lower extremities. Dangling the patients legs and applying pillows may further compromise venous return.
A nurse is creating an education plan for a patient with venous insufficiency. What measure should the nurse include in the plan?
- A. Avoiding tight-fitting socks.
- B. Limit activity whenever possible.
- C. Sleep with legs in a dependent position.
- D. Avoid the use of pressure stockings.
Correct Answer: A
Rationale: Measures taken to prevent complications include avoiding tight-fitting socks and panty girdles; maintaining activities, such as walking, sleeping with legs elevated, and using pressure stockings. Not included in the teaching plan for venous insufficiency would be reducing activity, sleeping with legs dependent, and avoiding pressure stockings. Each of these actions exacerbates venous insufficiency.
The triage nurse in the ED is assessing a patient who has presented with complaint of pain and swelling in her right lower leg. The patients pain became much worse last night and appeared along with fever, chills, and sweating. The patient states, I hit my leg on the car door 4 or 5 days ago and it has been sore ever since. The patient has a history of chronic venous insufficiency. What intervention should the nurse anticipate for this patient?
- A. Platelet transfusion to treat thrombocytopenia
- B. Warfarin to treat arterial insufficiency
- C. Antibiotics to treat cellulitis
- D. Heparin IV to treat VTE
Correct Answer: C
Rationale: Cellulitis is the most common infectious cause of limb swelling. The signs and symptoms include acute onset of swelling, localized redness, and pain; it is frequently associated with systemic signs of fever, chills, and sweating. The patient may be able to identify a trauma that accounts for the source of infection. Thrombocytopenia is a loss or decrease in platelets and increases a patients risk of bleeding; this problem would not cause these symptoms. Arterial insufficiency would present with ongoing pain related to activity. This patient does not have signs and symptoms of VTE.
