a, d, e
A client has been encouraged to increase fluid intake. Which measure would be most effective for the nurse to implement? a. explaining the mechanisms involved in transporting fluids to and from intracellular compartments b. keeping fluids readily available for patient c. emphasizing the long-term outcome of increasing fluids when the patient returns home d. planning to offer most daily fluids in the evening
b
Causes of Hypovalemia (FVD)
blood loss shock too much diuretic too much hypotonic sweating, vomiting, diarrhea burns (third spacing) advanced liver disease diabetes indipidus too much GI suction decrease access to fluid
A nurse is performing physical assessments for clients with fluid imbalance. Which finding indicates a fluid volume excess? a. a pinched and drawn facial expression b. deep, rapid respirations c. crackles heard upon auscultation d. tachycardia
c
A patient is admitted with exacerbation of CHF. What would you expect to find during your admission assessment? a. flat neck and hand veins b. furrowed dry tongue c. increased BP and crackles throughout the lungs d. bradycardia and pitting edema in lower extremities
c
In report from a transferring family you receive information that your patient's magnesium level is 1.2. When the patient arrives you are ordered by the doctor to administer Magnesium Sulfate via IV. Which of the following interventions takes priority? a. set up bedside suction b. set up IV antropine at bedside due to bradycardia effects of Magnesium Sulfate c. monitor the patient for reduced deep tendon reflexes and initiate seizure precautions d. none of the above
c
Insensible fluid losses include: a. gastric drainage b. urine c. perspiration d. bleeding
c
The nurse prepares for the possibility of magnesium sulfate toxicity by having at the bedside: a. suction equipment b. nalline c. calcium gluconate d. oxygen
c
Causes of Hypervolemia (FVE)
chf too much fluid renal failure third-spacing sodium retention inflammation severe stress excess corticosteroid
A nurse is assessing infants in the NICU for fluid balance status. Which nursing action would the nurse depend on as the most reliable indicator of a patient's fluid balance status? a. recording I/O b. testing skin turgor c. reviewing the complete blood count d. measuring weight daily
d
The physician has ordered IV replacement of potassium for a patient with severe hypokalemia. The nurse would administer this : a. diluted in 10cc over 10 min b. IV push c. rapid bolus d. diluted in 100cc over 1 hour with an infusion pump
d
You are taking a patient's BP manually. As you pump up the cuff above the systolic pressure, you notice that the patient develops a carpal spasm. Which of the following is true? a. the patient is having a normal nervous response to an inflating blood pressure cuff that is inflated above the systolic pressure b. this is known as trousseau's sign and is present in patients with hypercalcemia c. this is known as chvostek's sign d. this is known as trousseau's sign and is present in patients with hypocalcemia
