Question 1 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 2 of 5
A drug for which research has shown an adverse effect in animals but not in pregnant women would be categorized as Category
Correct Answer: C
Rationale: Category C drugs show animal adverse effects (e.g., fetal harm) but lack human data, fitting this scenario-risk can't be ruled out. Category A is safe in humans. B has no animal or human risk. D has human risk evidence. C balances uncertainty, per FDA.
Question 3 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.
Question 4 of 5
The nurse is aware that the following solutions are routinely used to flush an IV device before and after the administration of blood to a patient is:
Correct Answer: A
Rationale: 0.9 percent sodium chloride (normal saline) is the standard solution used to flush IV devices before and after blood transfusions. It is isotonic and compatible with blood products, preventing hemolysis or clotting. Dextrose solutions and sterile water are not used because they can cause hemolysis of red blood cells. Heparin sodium is used for maintaining patency in certain IV lines but is not suitable for blood transfusions. Therefore, normal saline is the correct choice for flushing IV devices in this context.
Question 5 of 5
A 19-year-old female is brought to the emergency department by a friend concerned with a change in her behavior during a party. The patient is agitated, anxious, and exhibits paranoid reactions to the physical exam. Her pulse is 120 beats/minute and her blood pressure is 150/100 mm Hg. She also complains of 'bugs' crawling all over her skin, although there is nothing there. Which of the following drugs has she most likely taken?
Correct Answer: A
Rationale: Agitation, paranoia, tachycardia, hypertension, and formication (bugs on skin) suggest cocaine . Heroin causes sedation. LSD induces hallucinations but less autonomic stimulation. Methanol and Propofol (E) don't fit. Cocaine's stimulant effects match this acute presentation.
