Virtual ATI Pharmacology Pre Assessment Questions
Question 1 of 4
Which of the following is NOT an eicosanoid?
Correct Answer: D
Rationale: Kallidin is a peptide, specifically a kinin, and is not classified as an eicosanoid. Eicosanoids are a group of lipid mediators derived from arachidonic acid or other fatty acids, including prostaglandins, prostacyclin, thromboxane, and leukotrienes. Although kallidin also plays a role in inflammation and vasodilation like some eicosanoids, it is not part of the eicosanoid family.
Question 2 of 4
An older adult patient with a hip fracture became unresponsive 20 minutes after receiving morphine 3 mg intravenously. Which actions would the nurse take?
Correct Answer: C
Rationale: The patient's unresponsiveness after receiving morphine is likely due to opioid-induced respiratory depression, a potentially life-threatening side effect. The nurse should first assess the patient's airway, breathing, and circulation (ABCs) and call for additional assistance. Supporting breathing with a bag-valve-mask device is critical to ensure adequate oxygenation. Naloxone, an opioid antagonist, should be prepared to reverse the effects of morphine. Flumazenil (A) is used for benzodiazepine overdose, not opioids. Reporting a stroke (B) is incorrect because the symptoms are consistent with opioid toxicity, not a stroke. Explaining unresponsiveness as a desired outcome (D) is inappropriate and dangerous.
Question 3 of 4
A patient is taking aspirin for arthritis. Which adverse reaction should the nurse teach the patient to report to the health care provider?
Correct Answer: A
Rationale: Tinnitus, or ringing in the ears, is a classic sign of aspirin toxicity, also known as salicylism. Aspirin can cause ototoxicity at high doses, leading to hearing disturbances. Patients taking aspirin for arthritis are often on long-term therapy, which increases the risk of toxicity. Seizures, sinusitis, and palpitations are not typically associated with aspirin use. Therefore, nurses should educate patients to report tinnitus immediately, as it may indicate the need for dose adjustment or discontinuation of the medication to prevent further complications.
Question 4 of 4
Walter, a teenage patient is admitted to the hospital because of acetaminophen (Tylenol) overdose. Overdoses of acetaminophen can precipitate life-threatening abnormalities in which of the following organs?
Correct Answer: B
Rationale: Acetaminophen overdose is hepatotoxic and can cause severe liver damage, leading to liver failure if not treated promptly. The liver metabolizes acetaminophen into a toxic metabolite, N-acetyl-p-benzoquinone imine (NAPQI), which depletes glutathione stores and causes cellular damage. Early administration of N-acetylcysteine (NAC) is critical to prevent irreversible liver damage. While kidney injury can occur, it is less common than liver damage.
