A nurse is assessing a client who has chronic venous insufficiency. Which of the following findings should the nurse expect?

Thick, deformed toenails

Edema

Dependent rubor

Hair loss

Answer and Explanation

The Correct Answer is B

Edema is a common finding in clients who have chronic venous insufficiency, due to the impaired venous return and increased capillary pressure. The edema is usually worse at the end of the day and improves with elevation.

a. Thick, deformed toenails are more likely to be seen in clients who have fungal infections or peripheral arterial disease, not chronic venous insufficiency.

c. Dependent rubor is a sign of peripheral arterial disease, not chronic venous insufficiency. It is a reddish color of the lower extremities that occurs when they are lowered and disappears when they are elevated.

d. Hair loss is another sign of peripheral arterial disease, not chronic venous insufficiency. It is caused by the reduced blood supply to the hair follicles.

Correct Answer is D

Explanation

Choice A reason:

Administering an anticholinesterase medication is not the primary intervention during a myasthenic crisis. While these medications can improve muscle strength in myasthenia gravis, they are not sufficient in the event of a crisis.

Choice B reason:

Pursed lip breathing is a technique used to manage dyspnea but is not adequate for the acute management of a myasthenic crisis, which can involve respiratory muscle paralysis.

Choice C reason:

Vasoconstrictors are not used in the treatment of myasthenic crisis. This condition is not related to vascular issues but to neuromuscular transmission failure leading to respiratory failure.

Choice D reason:

Mechanical ventilation is the correct intervention as it provides the necessary respiratory support when the patient's respiratory muscles are too weak to maintain adequate ventilation.

A. Avoid taking the medication prior to exercising. B. Stop taking the medication and notify your provider if you develop a headache. C. Place the tablet under your tongue, and then take a small sip of water. D. The medication can take up to 15 minutes to take eﬀect.
