Question 1 of 5
What is the therapeutic use of Albuterol?
Correct Answer: A
Rationale: Albuterol is a medication commonly used to treat asthma and other respiratory conditions. It works by relaxing the muscles in the airways, allowing the air passages to widen and making it easier to breathe. This bronchodilation effect helps to relieve symptoms such as wheezing, shortness of breath, and chest tightness. Albuterol is classified as a short-acting beta-agonist, and its therapeutic use lies in its ability to provide quick relief during acute asthma attacks or to prevent exercise-induced bronchospasm.
Question 2 of 5
A 20-year-old female with a history of substance abuse has delivered a child whose weight is less than the 10th percentile. Other findings include small head and flat midface. The patient has an atrial septal defect. Which of the following substances may have caused these symptoms?
Correct Answer: A
Rationale: Fetal alcohol syndrome (FAS) from alcohol causes growth restriction, microcephaly, flat midface, and cardiac defects. Cocaine , Marijuana , Opioids , and Tobacco (E) don't fully match. Alcohol's teratogenicity explains the infant's features.
Question 3 of 5
A client tells a nurse, "I don't get the same relief as I used to with this pain medication." The nurse should recognize that the client is experiencing which of the following?
Correct Answer: C
Rationale: Drug tolerance occurs when a person needs more of a drug to achieve the same effect they initially experienced with a lower dose. In this scenario, the client mentioning that they do not get the same relief with the pain medication suggests that their body has built up a tolerance to the medication. This is different from drug addiction, which involves a psychological and physical reliance on a drug, and physical dependence, which is the body's adaptation to a drug leading to withdrawal symptoms when the drug is stopped. Psychological dependence involves a perceived need for a drug due to psychological reasons rather than physical necessity. In this case, the client's statement points to drug tolerance as the likely reason for experiencing decreased effectiveness of the pain medication.
Question 4 of 5
A 63-year-old man presents to the emergency department with altered mental status after ingesting an entire bottle of acetaminophen. The patient's heart rate is 120 beats/minute, blood pressure is 100/58 mm Hg, and respiration rate is 28/minute. His aspartate aminotransferase and alanine aminotransferase are 4,128 IU and 3,978 IU, respectively. What is the most appropriate treatment for this patient?
Correct Answer: C
Rationale: Acetaminophen overdose with liver failure (elevated AST/ALT) needs N-acetylcysteine , restoring glutathione to detoxify NAPQI. Ammonium chloride and flumazenil are irrelevant. Naloxone treats opioids. Sodium bicarbonate (E) doesn't apply. N-acetylcysteine is critical.
Question 5 of 5
Which of the following drugs can suppress seizure activity and decrease the frequency of migraine headache?
Correct Answer: D
Rationale: Valproate is a medication commonly used to treat seizures and prevent migraine headaches. It acts by suppressing seizure activity and stabilizing electrical activity in the brain. Valproate is a broad-spectrum anticonvulsant drug that can be an effective treatment for epilepsy and migraine prophylaxis. It works by increasing the levels of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, thus reducing the frequency and severity of seizures and migraine attacks. Glipizide is an oral antidiabetic drug used to treat type 2 diabetes, hydrochlorothiazide is a diuretic used to treat high blood pressure, and atropine is a medication with various uses, including dilating the pupils and reducing secretions during surgery.
