Isotonic
A client has the following arterial blood gas results: pH: 7.33 PaCO2: 42 mm Hg HCO3: 19 mEq/L (19 mmol/L) PaO2: 95 mm Hg Which imbalance would the nurse suspect?
Metabolic acidosis

Nutrition management Intravenous therapy Electrolyte management
An older adult has fluid volume deficit and needs to consume more fluids. Which approach by the nurse demonstrates gerontologic considerations?
Offer small amounts of preferred beverage frequently.
Which nursing actions would be performed when preparing an IV solution and tubing to initiate intravenous therapy? Select all that apply.
Remove cap at end of tubing, release clamp, and allow fluid to move through tubing. Maintain aseptic technique when opening sterile packages and IV solution. Clamp tubing, uncap spike, and insert into entry site on bag as manufacturer directs. Apply label to tubing reflecting the day/ date for next set change, per facility guidelines.
The nurse is describing the role of antidiuretic hormone in the regulation of body fluids. What phenomenon takes place when antidiuretic hormone is present?
The renal system retains more water.
The nurse is assessing a client's intravenous line and notes small air bubbles within the tubing. What is the priority nursing action?
Tighten the roller clamp to stop the infusion.
When the nurse is starting an intravenous infusion on a client who will be receiving multiple intravenous antibiotics, which guideline should the nurse follow?
Use distal veins before proximal veins.
Which client would be a candidate for total parenteral nutrition?
a client with colitis and bloody diarrhea
After surgery, a client is on IV therapy for the next 4 days. How often should the nurse change the IV tubing for this client?
every 72 hours
When an older adult client receiving a blood transfusion presents with an elevated blood pressure, distended neck veins, and shortness of breath, the client is most likely experiencing:
fluid overload.
A dialysis unit nurse caring for a client with renal failure will expect the client to exhibit which fluid and electrolyte imbalances?
fluid volume excess and acidosis
A nurse is assessing clients across the lifespan for fluid and electrolyte balance. Which age group would the nurse identify as having the greatest risk for these imbalances?
infants
Mr. Jones is admitted to the nurse's unit from the emergency department with a diagnosis of hypocalcemia. His laboratory results show a serum calcium level of 8.2 mg/dL (2.05 mmol/L). For what assessment findings will the nurse be looking?
muscle cramping and tetany

As part of the presentation, the nurse plans to discuss how the intake and output of fluids is typically balanced each day. When describing the normal daily output of fluids, which component would the nurse identify as accounting for the smallest amount of fluid output?
perspiration
A client has been receiving intravenous (IV) fluids that contain potassium. The IV site is red and there is a red streak along the vein that is painful to the client. What is the priority nursing action?
remove the IV.
The student nurse asks, "What is intravascular fluid?" What is the appropriate nursing response?
"Watery plasma, or serum, portion of blood."
