The RN is caring for a client who is severely dehydrated. Which nursing action can be delegated to the
unlicensed assistive personnel (UAP)?
A. Consulting with a health care provider about a client's laboratory results
B. Infusing 500 mL of normal saline over 60 minutes
C. Monitoring IV fluid to maintain the drip rate at 75 mL/hr
D. Providing oral care every 1 to 2 hours
D. Providing oral care every 1 to 2 hours
RATIONALE:
Appropriate intervention by an UAP to a client who is severely dehydrated is to provide oral care every 1
to 2 hours. Frequent oral care is important for a client with fluid volume deficit.Consulting with a
primary care provider about a client's laboratory results, infusing 500 mL of normal saline, and
monitoring IV fluids are complex actions and would be performed by licensed personnel.
The charge nurse on a medical-surgical unit is completing assignments for the day shift. Which client is
most appropriate to assign to the LPN/LVN?
A. A 44-year-old with congestive heart failure (CHF) who has gained 3 pounds (1.4 kg) since the
previous day
B. A 58-year-old with chronic renal failure (CRF) who has a serum potassium level of 6 mEq/L (6.0
, mmol/L)
C. A 76-year-old with poor skin turgor who has a serum osmolarity of 300 mOsm/kg (300 mmol/kg)
D. An 80-year-old with 3+ peripheral edema and crackles throughout the posterior chest
C. A 76-year-old with poor skin turgor who has a serum osmolarity of 300 mOsm/kg (300 mmol/kg)
RATIONALE:
The most appropriate client for the nurse to assign to the LPV/LVN is the 76-year-old adult with poor
skin turgor and a serum osmolarity of 300 mOsm/kg (300 mmol/kg). Although the 76-year-old client has
poor skin turgor, the serum osmolarity indicates normal fluid balance. This client is the most stable of
the four clients described.The 44-year-old with CHF who has gained 3 pounds (1.4 kg) since the previous
day requires additional assessments and interventions which should be performed by an RN. The data
about the 58-year-old client with CRF and a serum potassium level of 6 mEq/L (6.0 mmol/L) has a risk for
dysrhythmia and instability. Assessments and interventions performed by an RN are also needed on this
client. The data about the 80-year-old client with edema and congested lungs indicate that the client is
not stable, requiring ongoing assessments and interventions by an RN.
The nurse is caring for a client receiving lactated Ringer's solution IV for rehydration. Which
assessments will the nurse monitor during intravenous therapy?
SELECT ALL THAT APPLY
A. Blood serum glucose
B. Blood pressure
C. Pulse rate and quality
D. Urinary output
E. Urine specific gravity
B, C, D, E
RATIONALE:
The two most important areas to monitor during rehydration are pulse rate and quality and urine
output. In addition, decreasing specific gravity of urine is also an indication of rehydration. Blood
pressure is another important vital sign to monitor during rehydration.Blood glucose changes do not
have a direct relation to a client's hydration status; lactated ringers are free from glucose.
The rapid response team (RRT) is called to the bedside of a client with heart rate of 38 beats per
minute and a potassium level of 7.0 mEq/L (7.0 mmol/L). For which medication will the nurse
anticipate a prescription?
A. Insulin
B. atropine
C. Sodium polystyrene sulfonate (Kayexalate)
D. potassium phosphate
A. Insulin
