A nurse is assessing an older adult client. Which of the following should the nurse identify as an expected physiological change associated with aging?
Increased sensitivity to touch.
Decreased peripheral circulation.
Decreased airway resistance.
Increased appetite.
The Correct Answer is B
Choice A rationale:
Increased sensitivity to touch is not an expected physiological change associated with aging. Older adults often experience decreased sensitivity to touch due to changes in nerve endings and decreased skin elasticity. This can lead to decreased sensation rather than increased sensitivity.
Choice B rationale:
Decreased peripheral circulation is an expected physiological change associated with aging. With age, blood vessels can become less elastic and more narrow, leading to reduced blood flow to the extremities. This can result in cold extremities, delayed wound healing, and increased vulnerability to skin breakdown. Nurses should assess for signs of impaired circulation in older adult clients and provide appropriate interventions to prevent complications.
Choice C rationale:
Decreased airway resistance is not an expected physiological change associated with aging. Older adults often experience increased airway resistance due to changes in lung elasticity and chest wall compliance. This can lead to decreased lung function and a higher risk of respiratory issues such as pneumonia and bronchitis.
Choice D rationale:
Increased appetite is not an expected physiological change associated with aging. In fact, many older adults experience a decrease in appetite due to factors such as changes in metabolism, decreased sense of taste and smell, and underlying health conditions. This reduced appetite can contribute to malnutrition and weight loss in the elderly population.

Correct Answer is D
Explanation
Choice A rationale:
Using a 5-mL syringe to flush the catheter is not the best choice. Central venous access devices typically require a larger syringe for flushing to prevent excessive pressure and potential damage to the catheter. A smaller syringe like the 5-mL syringe can create higher pressure, which could cause complications.
Choice B rationale:
Changing the site dressing and stabilization device every 24 hours is not the recommended practice. The dressing and stabilization device should be changed according to facility policy and as needed, but a rigid 24-hour schedule is not necessary and might increase the risk of infection due to unnecessary exposure.
Choice C rationale:
Expecting blood to appear in the catheter lumen after flushing is incorrect. Blood in the catheter lumen after flushing could indicate complications such as a dislodged catheter or other issues requiring immediate attention. The catheter should ideally remain patent without the presence of blood.
Choice D rationale:
This is the correct choice. Using chlorhexidine solution to clean the catheter is an evidence-based practice to prevent infection at the insertion site. Chlorhexidine has broad-spectrum antimicrobial properties and helps reduce the risk of catheter-related infections.
Correct Answer is C
Explanation
Choice A rationale:
Metabolic acidosis is not the correct acid-base imbalance for the given ABG results. Metabolic acidosis is characterized by a low pH (acidic), low bicarbonate (HCO3) levels, and a compensatory decrease in the PaCO2. In the provided ABG results, the pH is elevated, and both the PaCO2 and HCO3 levels are within normal ranges.
Choice B rationale:
Respiratory acidosis is also not the correct acid-base imbalance for the given ABG results. Respiratory acidosis occurs when there is an elevation in PaCO2 due to inadequate ventilation, leading to an acidic pH. In the provided ABG results, the pH is elevated, and the PaCO2 level is within normal range.
Choice C rationale:
Metabolic alkalosis is the correct acid-base imbalance for the given ABG results. Metabolic alkalosis is characterized by an elevated pH, elevated bicarbonate (HCO3) levels, and a compensatory increase in PaCO2. In this case, the pH is higher than the normal range, the HCO3 level is elevated, and the PaCO2 is also slightly increased as the body attempts to compensate.
Choice D rationale:
Respiratory alkalosis is not the correct answer based on the provided ABG results. Respiratory alkalosis is marked by an elevated pH and a decrease in PaCO2 due to excessive ventilation. In the given ABG results, the pH is elevated, but the PaCO2 is not decreased; it's within the normal range.
