A nurse is caring for an older adult client.
The client has an increased risk for dehydration due to which of the following physiological changes that can occur with aging?
Decrease in systolic blood pressure
Increase in saliva production
Increase in percentage of body water
Decrease in kidney function
Decrease in kidney function
The Correct Answer is D
Choice A rationale
A decrease in systolic blood pressure is not a physiological change that increases the risk of dehydration in older adults.
Choice B rationale
An increase in saliva production does not occur with aging and does not increase the risk of dehydration.
Choice C rationale
An increase in the percentage of body water does not occur with aging. In fact, total body water decreases with age, which can contribute to an increased risk of dehydration.
Choice D rationale
A decrease in kidney function is a common physiological change that occurs with aging. This can lead to a decreased ability to concentrate urine and conserve water, increasing the risk of dehydration.

Step 1 is to verify the provider’s order to discontinue the tube. It is crucial to ensure that the removal of the NG tube is in accordance with the provider’s orders before proceeding with the removal process.
Correct Answer is B
Explanation
Choice A rationale
Respiratory alkalosis is typically associated with hyperventilation, which can occur in conditions such as anxiety, fever, or certain lung diseases. However, it is less likely in a patient who is nauseous and vomiting.
Choice B rationale
Metabolic alkalosis is a condition that can occur due to the loss of acid from the body, which can happen when a patient is vomiting. When a person vomits, they lose stomach acid (hydrochloric acid), and this can disrupt the acid-base balance in the body, leading to metabolic alkalosis.
Choice C rationale
Metabolic acidosis is typically associated with conditions that cause the accumulation of acid in the body or the loss of bicarbonate, such as kidney disease, lactic acidosis, or certain poisonings. It is less likely in a patient who is nauseous and vomiting.
Choice D rationale
Respiratory acidosis is typically associated with conditions that cause an inability to remove enough carbon dioxide from the body, such as chronic obstructive pulmonary disease (COPD) or airway obstruction. It is less likely in a patient who is nauseous and vomiting.
