when a physician orders medication for a geriatric patient, why must adaptations be made for the age of the person?
Age-related changes in metabolism, excretory function, nutritional function, and nutrient distribution necessitate adaptations.
If the dosage is not changed, the medicine may become useless or even accumulate and become dangerous to the body.The specialty of geriatrics is the care of the elderly. As a result of aging, older people usually become weaker. Therefore, they should be distinguished from young people. The medical field of geriatrics is solely focused on providing high-quality, patient-centered care to the elderly. Clinicians specializing in geriatrics are trained to focus on issues and concerns specific to older people.Many adaptations are required for a geriatric patient.

the nurse plans to assess a patient’s respiratory rate; however, the patient has just returned from ambulating to the bathroom. what should the nurse do to minimize the effect of exercise on the patient’s respiratory rate?
Encourage the patient to rest for 10 minutes before assessing respiration.
Respiration rate is another name for respiratory rate. This represents how many times you are breathing in one minute. You can find out your breathing rate by counting how many times you breathe in one minute while you are at rest. To get an accurate measurement: Sit comfortably. The ideal position for measuring respiration is a chair or bed with a backrest. Count the number of thoracic or abdominal undulations per minute to determine the respiratory rate. Make a note of this number. Worse, this vital sign is often misjudged or ignored. An important vital indicator and a fundamental component of patient assessment is respiratory rate (RR). Physiological demand often causes RR fluctuations automatically, but RR can also be intentionally increased or decreased over short periods of time.Therefore, the patient must be resting before the assessment.

A stroke occurs when an artery that directly feeds into the heart muscle has become completely blocked. True or false?.
The statement "A stroke occurs when an artery that directly feeds into the heart muscle has become completely blocked." is false.
This is false since it isn't such a thing as a heart attack. A stroke occurs when a cerebral artery becomes clogged. When blood cannot flow to the brain, a stroke happens.
The obstruction or rupture of a blood artery in the brain, which both restrict oxygen from reaching the brain tissue, is what usually causes this disturbance of blood flow. When blood supply to the heart is restricted, the heart muscle suffers significant damage, which results in a heart attack.
Coronary artery disease, a disorder that develops as plaque builds up in the arteries, is what leads to the majority of heart attacks. Over time, the plaque limits blood flow, making the heart work harder and increasing the risk of heart muscle failure or injury.
