A nurse is caring for a patient immediately following a cardiac catheterization with a femoral artery approach. Which action should the nurse take?

Remind the patient not to turn from side to side.

Keep the patient in a high-Fowler’s position for 6 hours.

Perform passive range-of-motion for the affected extremity.

Check pedal pulses every 15 minutes.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

It is not necessary to remind a patient to avoid turning from side to side after femoral artery catheterization. Restricting movement in this way could actually increase the risk of complications such as deep vein thrombosis (DVT).

Early ambulation is generally encouraged to promote circulation and prevent blood clots.

Patients are typically allowed to turn and reposition themselves as needed for comfort, unless there are specific contraindications.

Choice B rationale:

Keeping the patient in a high-Fowler's position for 6 hours is not a standard recommendation following femoral artery catheterization.

The patient's position should be based on their individual needs and comfort level.

In some cases, a slight elevation of the head of the bed may be helpful to promote venous return, but prolonged high-Fowler's positioning is not necessary.

Choice C rationale:

Passive range-of-motion exercises are not typically performed on the affected extremity immediately following femoral artery catheterization.

This is because there is a risk of dislodging the catheter or causing bleeding at the puncture site.

Once the catheter has been removed and the puncture site has healed, gentle range-of-motion exercises may be recommended to help maintain joint mobility.

Choice D rationale:

Checking pedal pulses every 15 minutes is essential to assess for adequate circulation to the lower extremities following femoral artery catheterization.

This is because there is a risk of complications such as thrombosis or embolism, which can compromise blood flow to the legs and feet.

If the pedal pulses are weak or absent, it could indicate a serious problem that requires immediate intervention.

Correct Answer is C

Explanation

Choice A rationale:

Pallor, or paleness, is not a typical sign of phlebitis. It can be associated with other conditions such as anemia, decreased blood flow, or shock. In the context of IV therapy, pallor at the insertion site might suggest a problem with blood flow, such as infiltration or a clot, but it's not a direct indication of inflammation.

Choice B rationale:

Coolness at the IV site is also not a characteristic sign of phlebitis. It could potentially suggest infiltration of the IV fluids into the surrounding tissues, but it's not a primary indicator of inflammation. Phlebitis typically involves warmth and redness due to the inflammatory response.

Choice C rationale:

Erythema, or redness, is the hallmark sign of phlebitis. It's caused by the dilation of blood vessels in the area as part of the inflammatory response. The redness is often accompanied by warmth, swelling, and tenderness along the vein.

Mechanism of erythema in phlebitis:

When the inner lining of the vein (endothelium) is irritated or damaged by the IV catheter, it releases inflammatory mediators. These mediators cause the blood vessels to dilate, leading to increased blood flow and redness in the area.

The redness is often more pronounced along the path of the vein, rather than just at the insertion site.

Choice D rationale:

Drainage from the IV site can be a sign of infection, but it's not a primary feature of phlebitis. If drainage is present, it's important to assess for other signs of infection, such as pus, fever, or increased pain.

A. Encourage increased fluid intake B. Keep the affected knee flexed C. Promote bed rest for 5 days D. Massage the patient’s calf on the affected side . E. None F. None

Correct Answer is A

Explanation

The correct answer is Choice A.

Choice A rationale: Encouraging increased fluid intake helps maintain blood volume and reduces viscosity, promoting circulation and lowering the risk of venous stasis and clot formation postoperatively.

Choice B rationale: Keeping the affected knee flexed impairs venous return and increases stasis, elevating the risk of thrombosis. Proper positioning with extension promotes circulation and reduces clot risk.

Choice C rationale: Prolonged bed rest contributes to immobility-induced venous stasis, a major risk factor for DVT. Early ambulation and leg exercises are essential to prevent thromboembolic events.

Choice D rationale: Massaging the calf of a postoperative patient is contraindicated due to the risk of dislodging a thrombus, potentially leading to a life-threatening pulmonary embolism.
