Question 1 of 5
Which of the following are complications of Warfarin? (select all that apply)
Correct Answer: A
Rationale: Warfarin is an anticoagulant medication that works by inhibiting the body's ability to clot blood. While it is an effective medication for preventing blood clots and strokes, one of its major complications is the increased risk of bleeding. This can manifest as easy bruising, nosebleeds, bleeding gums, or more serious internal bleeding in organs such as the stomach or brain. Cramps, fever, and nausea are not common complications of Warfarin use.
Question 2 of 5
Propofol in comparison to thiopental sodium:
Correct Answer: C
Rationale: Propofol produces a faster and clearer recovery than thiopental sodium and is less irritant.
Question 3 of 5
A patient has been ordered the powdered form of the bile acid sequestrant colestipol. Which of the following does the nurse identify as true?
Correct Answer: D
Rationale: The correct statement is that the colestipol should be administered 1 hour before or 4 to 6 hours after any other oral medication. Bile acid sequestrants like colestipol can bind to other medications, reducing their absorption and effectiveness. Therefore, they should be taken separately from other medications to prevent any interactions. Additionally, colestipol should ideally be administered with meals to improve tolerability and adherence, although this was not one of the options given in the question.
Question 4 of 5
When taking Digoxin, low levels of what can cause
Correct Answer: A
Rationale: When taking digoxin, low levels of potassium can cause an increased risk of digoxin toxicity. This is because digoxin and potassium compete for binding sites on the sodium-potassium pump in cardiac cells. Low potassium levels can lead to enhanced binding of digoxin to these pumps, resulting in increased concentrations of digoxin within the cells and potential toxicity. Therefore, it is important to monitor potassium levels regularly while taking digoxin to prevent complications.
Question 5 of 5
The nurse teaches the client about the difference between oral and nasal decongestants. The nurse evaluates that learning has been effective when the client makes which statement?
Correct Answer: A
Rationale: Oral decongestants (e.g., pseudoephedrine) act systemically, raising blood pressure via vasoconstriction, a key difference from nasal decongestants (e.g., oxymetazoline), which act locally but risk rebound congestion. The statement 'Oral decongestants can cause hypertension' shows the client grasps this systemic effect, indicating effective teaching. Nasal decongestants aren't safe for a month ; they cause rebound after 3-5 days. Only nasal decongestants typically cause rebound , not oral. Oral efficacy varies, not inherently superior. Choice A reflects accurate understanding of oral decongestants' broader impact, critical for safe use, making it the best learning indicator.
