The blood pressure (BP) of a 71-year-old patient admitted with pneumonia is 160/70 mm Hg. Which age-related change contributes to this finding?

Stenosis of the heart valves.

Decreased adrenergic sensitivity.

Increased parasympathetic activity.

Loss of elasticity in arterial vessels.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Stenosis of the heart valves typically leads to murmurs and changes in heart sounds but does not directly impact blood pressure regulation.

Choice B rationale:

Decreased adrenergic sensitivity might lead to lower heart rate and blood pressure, not an increase in systolic blood pressure as seen in this case.

Choice C rationale:

Increased parasympathetic activity would lead to decreased heart rate, not an increase in systolic blood pressure as observed in the patient.

Choice D rationale:

Loss of elasticity in arterial vessels is the correct answer. With aging, arterial walls become less flexible and more rigid due to the accumulation of calcium and collagen. This loss of elasticity results in increased systolic blood pressure, which is the top number in a blood pressure reading. The diastolic pressure, represented by the bottom number, does not usually increase significantly with age. This change is a result of arteriosclerosis, which commonly occurs in elderly individuals.

Correct Answer is C

Explanation

Choice A rationale:

While leukemia treatment does have severe side effects, not all of them are permanent. It is essential for the patient to be aware of potential complications but also to understand that some side effects might be temporary and can be managed with appropriate care.

Choice B rationale:

Using the call light to ask for help when getting out of bed is essential for patients receiving chemotherapy, as their immune system might be compromised, making them prone to infections and injuries. However, this information is not specific to leukemia treatment but is a general safety measure for these patients.

Choice C rationale:

Patients undergoing chemotherapy for leukemia are at an increased risk of infections due to the suppression of the immune system. Preventive measures, such as good hygiene practices and early detection of signs of infection, are crucial in managing these patients. Educating the patient about infection prevention is essential for their safety during treatment.

Choice D rationale:

Feeling isolated can be a common emotional response to any chronic illness, including leukemia. However, it is not an unavoidable consequence, and providing emotional support and involving the patient in support groups can help mitigate these feelings. This statement does not provide essential information about managing leukemia treatment.

A. Methotrexate. B. Deferoxamine. C. Ferrous gluconate. D. Iron dextran complex.

Correct Answer is B

Explanation

Choice A rationale:

Methotrexate is a medication used for cancer and autoimmune diseases. It does not chelate iron and is not used to treat iron overload conditions like hemochromatosis.

Choice B rationale:

Deferoxamine is an iron chelating agent used to treat iron overload conditions like hemochromatosis. It binds to excess iron and promotes its excretion from the body, preventing complications such as organ damage.

Choice C rationale:

Ferrous gluconate is an iron supplement used to treat iron deficiency anemia. It would not be appropriate for a patient with hemochromatosis, a condition characterized by iron overload.

Choice D rationale:

Iron dextran complex is another form of intravenous iron used to treat iron deficiency anemia. It is not indicated for treating iron overload conditions like hemochromatosis.
