Question 1 of 5
A 37-year-old woman is brought to the emergency department by a friend after consuming an entire month's supply of amitriptyline. She is tachycardic, drowsy, nauseous, and has a headache. Which of the following could the physician administer to help this patient?
Correct Answer: A
Rationale: Amitriptyline overdose (TCA) causes anticholinergic and cardiac toxicity. Bicarbonate corrects acidosis and stabilizes sodium channels, reducing arrhythmias. Dimercaprol , Methylene blue , and Vitamin K (E) are irrelevant. Naloxone treats opioids. Bicarbonate's role in TCA overdose is critical for this presentation.
Question 2 of 5
When giving digoxin (Lanoxin) to a patient, the health care provider notices various
Correct Answer: D
Rationale: Digoxin toxicity can lead to serious complications, such as arrhythmias and heart failure. Digibind, also known as digoxin immune fab, is a specific antidote used to treat severe cases of digoxin toxicity. It works by binding to digoxin in the body and forming a complex that is then excreted through the kidneys, effectively reversing the toxic effects of digoxin. Naloxone is used to reverse opioid overdose, Vitamin K is used to reverse warfarin overdose, and Fluemanzil is not a medication used for reversing digoxin toxicity.
Question 3 of 5
Trimethoprim:
Correct Answer: B
Rationale: Trimethoprim inhibits dihydrofolate reductase, not activates it, blocking folate synthesis in bacteria, so that's false. It's a weak base, a true statement, aiding its concentration in acidic environments like urine. It has good prostate penetration, effective in prostatitis, making that false. It distributes into CSF, useful in meningitis, so that's incorrect. It's teratogenic, not harmless in pregnancy. Its basic nature enhances its antibacterial efficacy, a key pharmacokinetic advantage in urinary tract infections.

Question 5 of 5
A patient has been diagnosed with angina and will be given a prescription for sublingual nitroglycerin tablets. When teaching the patient how to use sublingual nitroglycerin, the nurse will include which instruction?
Correct Answer: C
Rationale: When teaching a patient how to use sublingual nitroglycerin tablets, the nurse should include the instruction that if the chest pain is not relieved after one tablet, the patient should call 911 immediately. This is because persistent chest pain could indicate a more serious cardiac event, such as a myocardial infarction, that requires prompt medical attention. It is important for the patient to seek emergency help if the chest pain is not relieved after taking one sublingual nitroglycerin tablet. Taking multiple doses without relief of symptoms can be dangerous and delay appropriate medical intervention.
