Aging ordinarily leads to decreases in which of the following?

Correct Answer: D

Rationale: The correct answer is D: Serum triiodothyronine (T3) and gastric pepsin. Aging typically leads to a decrease in serum T3 levels due to reduced thyroid function. Gastric pepsin production also decreases with age, impacting digestion. A: Creatinine clearance and insulin secretion typically decrease with kidney and pancreatic function decline, not necessarily solely due to aging. B: Blood CO2 levels and saliva production are not directly affected by aging but can be influenced by various health conditions. C: Left ventricle-wall thickness may increase with age due to conditions like hypertension, and skin healing time can be affected by various factors other than just aging. In summary, the correct answer stands out as age-related declines in serum T3 and gastric pepsin levels are more directly linked to the aging process compared to the other choices.

Correct Answer: C

Rationale: The correct answer is C: sleep apnea. Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep, which does not directly cause pneumonia. Aspiration from a poor swallow (A), community acquired pneumonia (B), and compromised immune function (D) are all known risk factors for pneumonia in older adults. Aspiration can lead to the entry of bacteria into the lungs, community-acquired pneumonia is a common cause of infection in the elderly, and compromised immune function makes older adults more susceptible to infections. Thus, sleep apnea is the only option that does not directly contribute to the development of pneumonia in older clients.

Correct Answer: A, B

Rationale: Step-by-step rationale: 1. Cultural awareness is crucial for understanding one's own biases and recognizing cultural differences. 2. Cultural knowledge involves understanding diverse cultural practices, beliefs, and values. 3. Cultural skills refer to the ability to effectively communicate and adapt care to meet individual cultural needs. 4. Cultural connections, while important, do not directly relate to providing culturally competent care. In summary, A and B are correct as they form the foundation for providing culturally competent care, while C and D do not encompass all aspects necessary for culturally competent care.

Correct Answer: B

Rationale: The correct answer is B because straining to void can lead to increased vagal stimulation, resulting in decreased blood pressure upon standing (orthostatic hypotension). A: age and walker use don't directly increase risk. C: a leg cast may not directly affect blood pressure. D: Premarin use is not a common cause of orthostatic hypotension.

Correct Answer: A

Rationale: The correct answer is A: Decreased lean body mass and decreased glomerular filtration rate. 1. Decreased lean body mass: With aging, there is a natural decline in muscle mass which can affect the distribution and metabolism of digoxin, potentially increasing its concentration in the body. 2. Decreased glomerular filtration rate: As individuals age, there is a decrease in kidney function, particularly in the glomerular filtration rate, which can lead to decreased excretion of digoxin, resulting in its accumulation and potential toxicity. Therefore, these age-related changes can place the older client at risk for digoxin toxicity. Summary: B: Increased muscle mass and improved renal function - This choice is incorrect as aging is associated with decreased muscle mass and declining renal function. C: Higher levels of albumin and increased drug metabolism - This choice is incorrect as aging is typically associated with decreased albumin levels and slower drug metabolism. D: Decreased hepatic function and increased body fluid
