A nurse is teaching a client who has peripheral arterial disease. Which of the following statements should the nurse include in the teaching to explain peripheral arterial disease?
A. "Blood flow is altered and causes blood to pool in the legs."
"Blood flow is altered and causes blood to pool in the legs." This statement inaccurately describes venous insufficiency rather than peripheral arterial disease (PAD). In PAD, blood flow is reduced or obstructed due to atherosclerosis, leading to inadequate oxygen supply to tissues rather than pooling of blood in the legs.
B. "Blood flow is altered due to atherosclerosis affecting the tissues' ability to receive oxygen-rich blood."
"Blood flow is altered due to atherosclerosis affecting the tissues' ability to receive oxygen-rich blood." This statement correctly explains the underlying pathology of peripheral arterial disease (PAD). Atherosclerosis, characterized by the buildup of plaque in the arteries, narrows or blocks blood flow, impairing the delivery of oxygen-rich blood to the tissues. This can result in symptoms such as pain, cramping, and tissue damage, especially during activity when oxygen demand increases.
C. "Blood flow is altered due to incompetent valves causing increased venous pressure."
"Blood flow is altered due to incompetent valves causing increased venous pressure." This statement describes venous insufficiency rather than PAD. In venous insufficiency, faulty valves in the veins result in increased venous pressure, leading to symptoms such as swelling, heaviness, and varicose veins, but it does not involve arterial obstruction as seen in PAD.
D. "Blood flow is altered due to excessive stretching of the ventricles impairing the heart to contract."
"Blood flow is altered due to excessive stretching of the ventricles impairing the heart to contract." This statement describes a condition related to the heart's function rather than peripheral arterial disease. Excessive stretching of the ventricles may occur in conditions such as heart failure, but it does not directly affect blood flow in the peripheral arteries as seen in PAD.

Similar Questions
A nurse is assessing a client who has peripheral venous disease. Which of the following findings should the nurse recognize as a manifestation of peripheral venous disease?
A. Diminished hair growth on the lower extremities
Diminished hair growth on the lower extremities: Diminished hair growth on the lower extremities is not typically a manifestation of peripheral venous disease. Instead, it may suggest poor circulation or arterial insufficiency.
B. Loss of pigmentation over the shin area
Loss of pigmentation over the shin area: Loss of pigmentation over the shin area can occur in conditions such as chronic venous insufficiency, which is a form of peripheral venous disease. However, it is not the most characteristic manifestation.
C. Shiny appearance to the lower extremities
Shiny appearance to the lower extremities: A shiny appearance to the lower extremities is often associated with arterial insufficiency rather than peripheral venous disease. It can indicate thinning of the skin due to poor circulation and oxygenation.
D. Swollen and enlarged veins
Swollen and enlarged veins: Swollen and enlarged veins, also known as varicose veins, are classic manifestations of peripheral venous disease. These veins result from venous insufficiency, which leads to blood pooling and increased pressure in the veins, causing them to dilate and become visibly enlarged.

A nurse is performing preoperative assessments on a client who has a suspected detached retina. Which of the following should the nurse expect to find?
A. Tonometer intraocular pressure reading 8 mm Hg
Tonometer intraocular pressure reading 8 mm Hg (Option A): A low intraocular pressure reading may indicate a detached retina. In a detached retina, the vitreous humor (gel-like substance in the eye) may leak into the space behind the retina, causing a decrease in intraocular pressure. However, it's important to note that intraocular pressure alone cannot definitively diagnose a detached retina, and further diagnostic tests, such as a dilated eye examination or retinal imaging, would be needed for confirmation.
B. Smooth retina edges identified on slit-lamp biomicroscope examination
Smooth retina edges identified on slit-lamp biomicroscope examination (Option B): In the case of a detached retina, the edges of the retina may appear irregular or undulating rather than smooth. This irregularity is often observed during a dilated eye examination rather than with a slit-lamp biomicroscope.
C. Visual acuity of 20/20 using the Snellen eye chart
Visual acuity of 20/20 using the Snellen eye chart (Option C): Visual acuity may be affected in a detached retina, depending on the extent and location of the detachment. However, visual acuity alone cannot confirm a detached retina, as other factors such as refractive errors or cataracts can also affect visual acuity.
D. Lens and cornea appear intact during ophthalmoscope exam
Lens and cornea appear intact during ophthalmoscope exam (Option D): While a detached retina may be visualized during an ophthalmoscope examination as a gray or whitish area behind the lens, the appearance of the lens and cornea being intact does not definitively diagnose a detached retina. A thorough dilated eye examination by an ophthalmologist is necessary for accurate diagnosis.

A nurse is collecting data from a client related to changes in vision. Which of the following statements indicates that the client might be developing a cataract?
A. "I can't see anything from the sides of my eyes."
"I can't see anything from the sides of my eyes." This statement suggests a visual field deficit, which may be indicative of conditions affecting peripheral vision, such as glaucoma, retinal detachment, or optic nerve disorders. It is not a typical symptom of cataracts.
B. "My vision is almost gone from the center part of my eye."
"My vision is almost gone from the center part of my eye." This statement indicates a central visual impairment, which is a common symptom of cataracts. Cataracts cause clouding of the lens, leading to blurred or dimmed vision, especially in the center of the visual field. This symptom often progresses gradually over time.
C. "My contact lenses just don't fit like they used to."
"My contact lenses just don't fit like they used to." This statement suggests discomfort or fit issues with contact lenses and is not specifically indicative of cataracts. It may be related to changes in the shape or health of the cornea, conjunctiva, or tear film.
D. "l keep seeing flashes of lights moving around in my eye."
"I keep seeing flashes of lights moving around in my eye." Flashes of light in the visual field are not typical symptoms of cataracts. They may indicate other ocular conditions such as vitreous detachment, migraines with aura, or retinal disorders.
