A nurse is assessing a client who has dehydration. Which of the
following assessments is the priority?
a. Skin turgor
b. Urine output
c. Weight
d. Mental status
Mental status
The greatest risk to this client is injury from declining mental status or a
fall from worsened dehydration. Therefore, assessing the client's mental
status is the priority.
The nurse should assess skin turgor to monitor the client's hydration
status. Poor skin turgor is a manifestation of dehydration. However,
another assessment is the nurse's priority.
,The nurse should assess urine output to monitor the client's hydration
status. Decreased urine output is a manifestation of dehydration.
However, another assessment is the nurse's priority.
The nurse should weigh the client because weight loss is a
manifestation of dehydration. Decreased weight is the best indication of
the client's fluid status. However, another assessment is the nurse's
priority.
A nurse is assessing a client who is using PCA following a thoracotomy.
The client is short of breath, appears restless, and has a respiratory
rate of 28/min. The client's ABG results are pH 7.52, PoO2 89 mm hg,
and HCO3- 24 mEq/L. Which of the following actions should the nurse
take?
a. Instruct the client to cough forcefully.
b. Assist the client with ambulation.
c. Provide calming interventions.
d. Discontinue the PCA.
Provide calming interventions
The client's respiratory rate is above the expected range. Calming the
client should decrease the respiratory rate, which will cause the client's
carbon dioxide levels to increase. This will help correct the pH
imbalance.
Ambulation can exacerbate the client's respiratory distress and is not
appropriate at this time.
, Coughing forcefully and Discontinuing the PCA will not treat the
underlying cause of the ABG results.
A nurse is caring for a client who has a sodium level of 155 mEq/L.
Which of the following IV fluids should the nurse anticipate the
provider to prescribe?
a. Dextrose 5% in 0.9% sodium chloride
b. Dextrose 5% in lactated Ringer's
c. 3% sodium chloride
d. 0.45% sodium chloride
0.45% sodium chloride
A sodium level of 155 mEq/L is an indication of hypernatremia. The
nurse should anticipate a prescription for a hypotonic solution. The
0.45% sodium chloride is a hypotonic solution used to provide free
water and treat cellular dehydration, which promotes waste elimination
by the kidneys.Dextrose 5% in 0.9% sodium chloride is a hypertonic
solution. The 3% sodium chloride is a hypertonic solution. Lactated
Ringer's solution contains sodium and other electrolytes and is not
indicated for hypernatremia.
A nurse is evaluating a client who is receiving IV fluids to treat
(isotonic) dehydration. Which of the following laboratory findings
indicates that the fluid therapy has been effective?
a. BUN 26 mg/dL
b. Serum sodium 138 mEq/L
