2. A patient is ordered furosemide 20 mg IV daily. The ampule provides 40mg/4ml. How many ml are needed for the correct dose? Answer:
want x drug form = 20 mg x 4ml = 80 ml = 2ml
have 40 mg 40
- The drug monograph suggests the medication can be given minibag or IV direct. Provide rationale for your decision about how you will deliver the medication.
Answer: either route is safe. Considering that the rationale for furosemide is to cause diuresis, IV direct might be the preferable option considering it is a smaller volume. Always consider patient factors in the decision to administer medications direct or via a mini bag (ie. IV site, preexisting health challenges)
- You are giving morphine 5 mg IV direct. The parenteral practices manual advises to administer maximum 2mg / minute. How many minutes should it take to administer the dose? Answer:
5 mg x minute = 2.5 minutes
5. You are administering a medication IV direct. As you start injecting the medication, you notice white crystals developing in the IV tubing. What is your next action?
|a.||Consider that this is an incompatibility issue||This is true but action is necessary|
|b.||Stop and flush the line with saline||Incorrect. Flushing the line with saline will cause some of the white crystals to go into the patients vascular circulation and potentially cause harm|
|c.||Stop and get a new IV administration set||Correct. It is important that the crystals not enter the patient’s vascular system|
|d.||Notify the prescriber||Incorrect. While this is a good strategy the first thing you need to do is protect the patient|
