A patient diagnosed with peripheral arterial disease is being educated about the benefits of walking for exercise. What information should the nurse emphasize?
Elevate the feet for 30 minutes after walking.
Avoid exercise that increases the heart rate.
Continue walking to the point of pain.
Do not walk if a leg ulcer develops.
The Correct Answer is C
Choice A rationale
Elevating the feet for 30 minutes after walking is not specifically beneficial for a patient with peripheral arterial disease (PAD). While elevation can help with conditions like edema, it does not directly address the issues associated with PAD12.
Choice B rationale
Avoiding exercise that increases the heart rate is not the best advice for a patient with PAD. Exercise, including activities that increase heart rate, can actually be beneficial. It can help improve circulation, which is often compromised in PAD12.
Choice C rationale
Continuing to walk to the point of pain is beneficial for patients with PAD. Walking, especially at a high intensity, can help improve symptoms of PAD. It can increase blood flow and oxygen supply to the muscles, which can help manage PAD symptoms.
Choice D rationale
While it’s important to care for any ulcers that develop and seek medical attention, stopping walking altogether if a leg ulcer develops is not necessary. Walking is a low-impact activity that can help improve mobility over time.

Correct Answer is B
Explanation
Choice A rationale
Pseudomembranous colitis and crystalluria are not typically associated with gentamicin use.
Choice B rationale
Gentamicin can cause ototoxicity, which can manifest as tinnitus (ringing in the ears), vertigo (a sensation of spinning), and hearing loss. Headaches can also occur as a side effect of gentamicin.
Choice C rationale
While gentamicin can cause nephrotoxicity (kidney damage), which could potentially affect electrolyte levels, a potassium level of 3.5 mg/dL is within the normal range. Therefore, this would not typically be assessed as a toxic effect of gentamicin.
Choice D rationale
Hypoglycemia and cardiac dysrhythmias are not typically associated with gentamicin use.
Correct Answer is A
Explanation
Choice A rationale
People with Type 1 diabetes have little or no insulin that can be released. This is because their pancreatic β-cells, which produce insulin, are destroyed by an autoimmune process. Without insulin, glucose cannot be taken up into cells to be used for energy. Oral antihyperglycemic agents work by increasing the release of insulin or increasing the body’s sensitivity to insulin, so they are not effective in Type 1 diabetes where there is an absolute insulin deficiency.
Choice B rationale
The cost of oral antihyperglycemic agents is not the primary reason they are not used in Type 1 diabetes. The main issue is the lack of insulin production, which these medications cannot address.
Choice C rationale
People with Type 1 diabetes do not typically have resistance to their endogenous insulin. Insulin resistance is more commonly associated with Type 2 diabetes.
Choice D rationale
While hypoglycemia can occur with the use of some antihyperglycemic agents, this is not the primary reason these medications are not used in Type 1 diabetes. The main issue is the absolute deficiency of insulin.
