Hyperactive deep tendon reflexes (DTRs)

During an assessment of an elderly client, the nurse notes an increase in pulse and respiration rates, and notes that the client has warm skin. The nurse also notes a decrease in the client's blood pressure. The nurse recognizes that what medical diagnosis may be responsible?

Hypovolemia

The nurse is caring for Mrs. Roberts, an 86-year-old patient, who fell at home and was not found for two days. Mrs. Roberts is severely dehydrated. The nurse is aware that elderly people are at increased risk for fluid imbalance for which of the following reasons?

Increasing ventilation through the lungs

Based on knowledge of total body fluids, a nurse is especially watchful for a fluid volume deficit in an infant. Why would the nurse do this?

Infants have more total body fluid and ECF than adults.

The nurse, along with a nursing student, is caring for Mrs. Roper, who was admitted with dehydration. The student asks the nurse where most of the body fluid is located. The nurse should answer with which of the following fluid compartments?
