A nurse is providing education to a group of older adults about the signs and symptoms of a myocardial infarction. Which of the following is not a sign of a myocardial infarction?

Cool, clammy skin

Chest pain radiating into the back and jaw

Nausea and vomiting

Peripheral edema

Answer and Explanation

The Correct Answer is D

A.   Cool, clammy skin can be a sign of a myocardial infarction. It occurs due to the body's stress response during an MI, leading to decreased perfusion and sweating. This symptom is consistent with the autonomic response to a heart attack.
B.   Chest pain radiating into the back, jaw, or arms is a classic symptom of myocardial infarction. This radiation of pain is due to the way pain signals are transmitted and referred from the heart to other parts of the body. It is a common and significant symptom of MI.

C.   Nausea and vomiting can occur during a myocardial infarction, particularly in older adults. These symptoms are related to the autonomic nervous system's response to the stress of an MI and can sometimes be the presenting symptoms, especially in women and older adults.
D.   Peripheral edema is generally not a direct symptom of myocardial infarction. It is more commonly associated with chronic heart failure or other conditions leading to fluid overload. While MI can lead to heart failure over time, peripheral edema itself is not a typical acute symptom of an MI.

Correct Answer is A

Explanation

A. AMD affects the macula, which is responsible for central vision and fine detail. As the condition progresses, patients often experience a gradual loss of central vision, which can make it difficult to read, recognize faces, and perform tasks that require sharp vision. Distortion of straight lines (metamorphopsia) is also common, where straight lines may appear wavy or bent.
B. Floaters and flashes of light are more commonly associated with conditions affecting the vitreous body of the eye or retinal detachment, rather than AMD. These symptoms can occur due to changes in the vitreous gel or as a result of other retinal issues, but they are not the primary symptoms of AMD.
C. Cloudy vision and glare are typically associated with cataracts, not AMD. Cataracts cause the lens of the eye to become cloudy, leading to blurred vision and increased sensitivity to glare. AMD does not cause the lens to cloud, so these symptoms are not characteristic of AMD.
D. Loss of peripheral vision is more characteristic of glaucoma rather than AMD. AMD primarily affects central vision, leaving peripheral vision relatively intact until the disease progresses to an advanced stage. Glaucoma, on the other hand, often leads to a gradual loss of peripheral vision.

A. Allows for long-term administration of chemotherapy B. Can be used to implant radioactive material for internal radiation treatments C. Eliminates the risk of infection associated with accessing a blood vessel D. Reduces the risk of nausea and vomiting caused by chemotherapy medication

Correct Answer is A

Explanation

A. Chemotherapy often requires multiple infusions over a long period, and a CVAD provides a reliable and convenient access point for these treatments. It allows for the continuous or intermittent administration of chemotherapy drugs, which are often irritating to veins and require precise dosing.
B. While CVADs are used for administering chemotherapy and other treatments, they are not typically used to implant radioactive material for internal radiation (brachytherapy).
C. While CVADs reduce the need for repeated venipunctures and can help manage the complications of frequent injections, they do not eliminate the risk of infection. CVADs can themselves become a source of infection if not properly maintained, as they are open to the external environment.
D. The placement of a CVAD does not directly affect the side effects of chemotherapy, such as nausea and vomiting. The CVAD’s role is primarily related to the administration of medications and access to blood vessels.
