The nurse is preparing to administer a 5 dextrose in water (D5W) infusion to a client. Which explanation as to why the infusion is ordered is the most accurate?
 
  1. This is a colloid, and will increase the client's blood pressure.
  2. This medication is isotonic in its container, but when infused, the solution becomes hypotonic.
  3. This medication is hypotonic and will cause fluid to shift from the intravascular space into the interstitial and intracellular spaces.
  4. This medication is hypertonic and will cause fluid to shift from the extravascular space into the vascular space.

Question 2

A client is scheduled receive a parenteral dose of magnesium sulfate. The nurse tests patellar reflexes and determines them to be absent. Which action by the nurse is the most appropriate?
 
  1. Administer the drug as ordered, as this is a normal finding.
  2. Hold the medication for 1 hour, then reassess.
  3. Hold the medication and notify the health care provider.
  4. Administer the drug after placing the client on a cardiac monitor.

Answer to Question 1

Correct Answer: 2
Rationale 1: D5W is not a colloid.
Rationale 2: D5W is isotonic in the container. When infused, the dextrose is quickly metabolized in the body, leaving only water, and the solution becomes hypotonic.
Rationale 3: D5W is not a hypotonic solution.
Rationale 4: D5W is not a hypertonic solution.
Global Rationale: D5W is isotonic in the container. When infused, the dextrose is quickly metabolized in the body, leaving only water, and the solution becomes hypotonic. D5W is not a colloid, hypotonic or hypertonic solution.

Answer to Question 2

Correct Answer: 3
Rationale 1: Absence of patellar reflexes is not a normal finding and is suggestive of magnesium toxicity.
Rationale 2: The health care provider should be notified about the absence of patellar reflexes, as the finding might indicate magnesium toxicity.
Rationale 3: Depression or absence of reflexes can indicate early magnesium intoxication.
Rationale 4: Absence of patellar reflexes is not a normal finding and is suggestive of magnesium toxicity.
Global Rationale: Depression or absence of reflexes can indicate early magnesium intoxication. Absence of patellar reflexes is not a normal finding and is suggestive of magnesium toxicity. The health care provider should be notified about the absence of patellar reflexes, as the finding might indicate magnesium toxicity. Absence of patellar reflexes is not a normal finding and is suggestive of magnesium toxicity.
