Question 3: The nurse is assessing residents at a summer picnic at the nursing
(see full question) facility. The nurse expresses concern due to the high heat and
humidity of the day. Although the facility is offering the residents

,plenty of
fluids for
fluid
maintenan
ce, the
nurse is
most
concerned
about
which?

, You selected: Insensible fluid loss

Correct

Explanation: Due to the high heat and humidity, geriatric clients are at a high risk
for insensible fluid loss through perspiration and vapor in the
exhaled air. These losses are noted as unnoticeable and
unmeasurable. Those with respiratory deficits and allergies may be
only able to be outside for a limited period. Those with
cardiovascular compromise may need to alternate outdoor activities
with indoor rest. (less)

(see full question) consistent with metabolic alkalosis?

pH and high plasma bicarbonate concentration. The HCO value is
below normal. The PaCO value and the oxygen saturation level are
within a normal range. (less)
