Answer to Question 1
C
With age, elastin in vessel walls decreases, making them stiffer. Systolic blood pressure (SBP) is increased in older adults because of a loss of arterial distensibility resulting from arterial stiffen-ing. The other responses do not offer any useful information on the cause of the patient's condi-tion.
Answer to Question 2
D
Older patients have difficulty excreting potassium because of age-related kidney changes. This patient also takes aldactone, a potassium sparing diuretic. If the patient adds a salt substitute, normally high in potassium, the chances of developing hyperkalemia are high. The nurse needs to provide education on other ways to flavor foods. The other diet choices are fine.
