ATI Pharmacology Practice B 2023 Questions
Question 1 of 5
The patient tells the nurse that she is interested in the human brain and questions which parts of the brain control anxiety and insomnia. What is the best reply by the nurse?
Correct Answer: A
Rationale: The limbic system (e.g., amygdala) drives anxiety-emotional response-while the reticular activating system (RAS) regulates sleep-wake, impacting insomnia, per neuroanatomy. Frontal lobes plan, not directly control these. Thalamus relays, not initiates. Hypothalamus affects sleep but less anxiety. Limbic-RAS pairing fits, answering precisely.
Question 2 of 5
Louie, who is to receive a blood transfusion asks the nurse what is the most common type of infection he could receive from the transfusion. The nurse teaches him that approximately 1 in 250,000 patients contract:
Correct Answer: C
Rationale: Hepatitis B infection is the most common serious infection that patients can contract from a blood transfusion. It is estimated that approximately 1 in 250,000 patients receiving a blood transfusion may contract Hepatitis B. Hepatitis B is a viral infection that affects the liver and can lead to serious complications if left untreated. Blood banks and healthcare facilities have strict screening and testing procedures in place to minimize the risk of transmitting Hepatitis B through blood transfusions. It is important for patients to be aware of this risk and to follow up with their healthcare provider if they experience any symptoms of Hepatitis B after a blood transfusion.
Question 3 of 5
A patient has just received a prescription for an enteric-coated stool softener. When teaching the patient, the nurse should include which statement?
Correct Answer: D
Rationale: Enteric-coated medications are designed to resist dissolution in the stomach and release the active ingredient in the intestines. Chewing or crushing the tablet can compromise the coating, leading to premature drug release and potential irritation of the stomach lining. Therefore, the nurse should instruct the patient to swallow the tablet whole without chewing. Taking the tablet with orange juice or avoiding other medications is not necessary, and crushing the tablet is contraindicated. Proper administration ensures the medication's effectiveness and minimizes the risk of adverse effects.
Question 4 of 5
A 19-year-old man attempts suicide after failing all of his college courses. He goes home and takes more than 90 digoxin tablets (0.25 mg each), ingesting them about 3 h prior to presentation at the emergency department. He is brought to the hospital by his brother. Vital signs are as follows: pulse is 50 beats/minute, and the electrocardiogram indicates third-degree heart block. Serum electrolytes are normal. Which of the following is the most important therapy to initiate in this patient?
Correct Answer: B
Rationale: Digoxin overdose (bradycardia, heart block) requires digoxin immune Fab , binding free digoxin to reverse toxicity. Amiodarone and lidocaine treat arrhythmias but not the cause. Potassium and verapamil (E) worsen hyperkalemia or block. Fab is urgent here.
Question 5 of 5
Which of the following is least likely to have an adverse drug interaction with phenelzine (a monoamine oxidase (MAO) inhibitor)?
Correct Answer: D
Rationale: Phenelzine, an MAOI, risks hypertensive crisis or serotonin syndrome with drugs increasing monoamines. Levodopa raises catecholamines, risking hypertension with MAOIs. Ropinirole, a dopamine agonist, may enhance monoamine effects, potentially hazardous. Tolcapone, a COMT inhibitor, increases levodopa levels, amplifying MAOI risks. Pseudoephedrine, a sympathomimetic, causes severe hypertension. Propofol, an anesthetic, acts via GABA without monoamine interaction, making it least likely to cause adverse effects with phenelzine. Its safety profile here is key for procedural use in MAOI patients.
