A client is receiving intravenous fluid therapy with 0.9% sodium chloride solution.
The nurse understands that this type of solution is classified as:
Hypotonic.
Isotonic.
Hypertonic.
Colloid.
Colloid.
The Correct Answer is B
An isotonic solution has the same concentration of solutes as the blood plasma. 0.9% sodium chloride solution is an example of an isotonic solution.
It is used to supply water and salt to the body and to prevent hypotension induced by spinal anaesthesia.
Choice A is wrong because a hypotonic solution has a lower concentration of solutes than the blood plasma.
It can cause water to move into the cells and cause them to swell.
Choice C is wrong because a hypertonic solution has a higher concentration of solutes than the blood plasma.
It can cause water to move out of the cells and cause them to shrink.
Choice D is wrong because a colloid solution contains large molecules that do not pass through the capillary walls.
It is used to increase the blood volume and pressure in cases of shock or severe blood loss.

Correct Answer is A
Explanation
This is because urinary catheters are a common source of catheter associated urinary tract infections (CAUTIs), which can lead to complications such as pyelonephritis, sepsis, and renal failure. Therefore, the nurse should remove the catheter as soon as possible to reduce the risk of infection and promote normal urinary function.
Choice B is wrong because ensuring that the catheter is properly secured to prevent accidental dislodgement is not a priority intervention for a patient with a urinary catheter.
While this is an important nursing action to prevent trauma and bleeding, it does not address the main complication of catheterization, which is infection.
Choice C is wrong because encouraging the patient to drink fluids to prevent dehydration is not a priority intervention for a patient with a urinary catheter.
While this is a good nursing practice to maintain hydration and renal perfusion, it does not affect the risk of infection associated with catheterization.
Choice D is wrong because administering antibiotics to prevent infection is not a priority intervention for a patient with a urinary catheter.
While this may be indicated for some patients who have signs and symptoms of UTI or who are at high risk of infection, it is not a routine measure for all patients with catheters and may contribute to antibiotic resistance.
Correct Answer is ["B"]
Explanation
The nurse should anticipate administering 0.9% sodium chloride solution and regular insulin infusion to a client with diabetic ketoacidosis (DKA).
Choice A is wrong because 0.45% sodium chloride solution is a hypotonic fluid that can cause cerebral edema in DKA patients.
Choice C is wrong because 5% dextrose in water solution can increase blood glucose levels and worsen hyperglycemia in DKA patients.
Choice D is wrong because lactated Ringer’s solution contains lactate, which can be converted to bicarbonate and cause metabolic alkalosis in DKA patients.
Normal ranges for blood glucose, pH, bicarbonate, and ketones are as follows3: Blood glucose: 70-130 mg/dL before meals, and less than 180 mg/dL after meals pH: 7.35-7.45
Bicarbonate: 22-26 mEq/L Ketones: negative or trace
