Q

What are the risks due to adequate respiration of the aging adult?

A

o The trachea stiffens due to calcification of its cartilage. This reduces the ability to cough because it blunts the laryngeal and coughing reflexes.
o Reduced number of nerve endings may lead to a weaker gag reflex.
o The lungs become smaller in size and weight. Connective tissues needed for effective respiration and ventilation in the lungs weaken. This leads to decreased elastic recoil. Respiration then requires the use of accessory muscles. This leads to lungs being stiffed.
o Alveoli are less elastic, develop fibrous tissue, contain fewer functional capillaries and have less surface area. This reduces gas exchange.
o Loss of skeletal muscle strength in the thorax and diaphragm. This combined with the loss resilient force (tissues) that holds the thorax in slightly contracted leads to Kyphosis or a look of having a “barrel chest”.
o These changes add up to a reduction in vital capacity. = Less air exchange and more secretions remaining in the lungs.

*respirations are easier to count for the older adult

Q

Pneumonia IS A LEADING CAUSE OF DEATH IN OLDER ADULTS what are the contributing factors:

A

o Poor chest expansion and more shallow breathing

Q

What are the risks of adequate circulation related to aging adults:

A

o Heart valves increase in thickness and rigidity R/T sclerosis and fibrosis
o Aorta becomes dilated
o Slight ventricular hypertrophy
o Myocardial muscle loses some of its contractile strength causes a reduction in cardiac output, meaning it is less efficient with increased activity or demands on the heart. Because it is stiffening and losing its strength. Not allowing chambers to empty as they should.
o Example: more people tend to die at night or early morning. They got up and went to the bathroom = heart attack because of increased activity in the heart
o Diastolic filling and systolic emptying require more time to complete the cycle.
o Calcification and reduced elasticity of vessels. Becomes less sensitive to baroreceptors Reduces regulation of blood pressure. Reduced arterial BP leads to decreased tissue profession.
o Changes are usually gradual and become more apparent when the older adult is placed under increased activity. Consider early morning walks to restroom – increased death

Q

What are gastrointestinal issues related to aging?

A

o Tongue atrophies decreases taste sensation
o Difficulty swallow can choke more easily, and can’t swallow their meds that easily. Now issue is can they take their pills now?? Taste can result in eating more or less or more salt since they can’t taste anymore which can lead to GI issues (malnutrition, obesity, high levels of salt)
o Saliva production decreases may cause swallowing to be more difficult
o Degenerative changes in the smooth muscle lining of the lower esophagus (presbyesophagus).
o Can lead to GERD, sit patient up to eat and after eating don’t let them lay down right away. They need to eat small and more frequent meals during the day and snacks.. overeating = aspiration=pneumonia.
o Weaker esophageal contractions
o Weakness of sphincter
o Decreased esophageal motility
o Decreased stomach motility
o Decreased elasticity of the stomach reduces the amount of food the stomach can accommodate.
o The stomach has a higher pH r/t a decline in hydrochloric acid and pepsin causing increased incidence of gastric irritation in older adults.
o Reduced pepsin interferes with absorption of protein.
o Reduced hydrochloric acid interferes with absorption of calcium, iron, folic acid, and vitamin B12.

o	Decreased sensory perception may lead to i	ncreased incidence of constipation, as can 	inactivity, reduced food and fluid intake, and low 	fiver diet.
o	Pancreas fibrosis, atrophy, and reduced 	pancreatic secretions may affect the digestion of 	fats.

Q

What are urinary elimination changes related to aging:

A

o Hypertrophy of the bladder muscle and thickening decreases the ability of the bladder to expand and reduces capacity, leading to urinary frequency and nocturia. Kidney circulation improves when a person is in a recumbent position and increase the need to void. This is not a normal part of aging and is related to other aging issues.
o Retention of urine due to neurological inefficiencies and a weaker bladder that does not empty properly.
o Woman: fecal impaction like constipation
o Men: prostatic hypertrophy
o Reduced filtration efficiency of the kidneys affects the body’s ability to eliminate drugs and causing higher blood urea nitrogen levels.
o Incontinence Also not a normal part of aging, but usually caused by age-related physical or mental disorders. It is common but not normal
o If a man is having a UTI is is a very serious issue, try to find underlying problem.
