Question 1 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 2 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 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
A patient will be receiving a thrombolytic drug as part of the treatment for acute myocardial infarction. The nurse explains to the patient that this drug is used for which purpose?
Correct Answer: C
Rationale: Thrombolytic drugs are used to dissolve blood clots (thrombi) that are causing blockages in blood vessels, such as the coronary arteries in the case of acute myocardial infarction (heart attack). By breaking down the clot, these drugs help to restore blood flow to the affected area, reducing damage to the heart muscle and improving the patient's prognosis. Thrombolytic therapy is time-sensitive and is most effective when administered soon after the onset of a heart attack to minimize the extent of heart muscle damage.
Question 5 of 5
A male client has erectile dysfunction. Which systems should be assessed that could contribute to the erectile dysfunction?
Correct Answer: A
Rationale: Erectile dysfunction (ED) often stems from cardiovascular issues, like atherosclerosis or hypertension, which impair blood flow to the penis, a vascular process essential for erection. The integumentary system, while relevant to skin health, doesn't directly influence ED unless severe conditions affect genital tissue, which is rare. Endocrine disorders, such as diabetes or low testosterone, disrupt hormonal balance critical for libido and erectile function, making it a key area. The nervous system, including spinal cord injuries or neuropathy, affects nerve signals for arousal, another vital component. Cardiovascular assessment is prioritized because ED can signal underlying heart disease, with shared risk factors like smoking or high cholesterol, and its vascular basis often precedes overt cardiac symptoms, necessitating a thorough check of circulation and heart health to pinpoint or rule out this common cause.
