Question 1 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 2 of 5
A patient who is taking clopidogrel (Plavix) and aspirin is preparing for orthopedic surgery. The nurse will consult with the surgeon and provide which instruction to the patient?
Correct Answer: A
Rationale: The correct instruction for the patient taking clopidogrel (Plavix) and aspirin prior to orthopedic surgery is to continue taking aspirin and stop taking clopidogrel 2 weeks before the surgery. This recommendation is based on the pharmacokinetics of clopidogrel, which has a longer duration of action and requires a longer timeframe for platelet function to return to baseline after discontinuation. Aspirin, on the other hand, has a shorter duration of action, and its antiplatelet effects diminish more rapidly once it is stopped. By continuing aspirin and stopping clopidogrel 2 weeks before surgery, the patient can minimize the risk of excessive bleeding during the surgical procedure while still maintaining some level of antiplatelet effect to prevent thrombotic events.

Question 4 of 5
A patient with elevated lipid levels has a new prescription for nicotinic acid (niacin). The nurse informs the patient that which adverse effects may occur with this medication?
Correct Answer: A
Rationale: Nicotinic acid, also known as niacin, is commonly associated with adverse effects of pruritus (itching) and cutaneous flushing (reddening of the skin). These effects are often dose-related and can be minimized if the medication is taken with food or slowly titrated up. Tinnitus and urine with a burnt odor are not typically associated with nicotinic acid. Myalgia (muscle pain) and fatigue are more commonly seen with statin medications rather than niacin. Blurred vision and headaches are not commonly reported side effects of nicotinic acid either.
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.
