Q1 QUESTION 1 OF 244
During what trimester is a pregnant woman most at risk for adverse drug reactions with potential long term consequences?
CORRECT ANSWER
1st trimester (fetus most at risk d/t rapid growth)
Page 1
, RATIONALE
The first trimester is characterized by critical organogenesis, making the developing fetus particularly susceptible to teratogenic effects of drugs, which can lead to
significant long-term developmental consequences. As fetal tissues rapidly proliferate and differentiate during this period, exposure to harmful substances poses the highest
risk for adverse outcomes.
Q2 QUESTION 2 OF 244
Physiological changes during pregnancy that impact pharmacodynamics and pharmacokinetic properties of drugs?
CORRECT ANSWER
increase glomerular filtration rate leads to increase durg excretion
increase hepatic metabolism
decrease tone and motility of bowel
increase drug absorption
RATIONALE
Increased glomerular filtration rate enhances renal clearance, leading to faster drug excretion, while elevated hepatic metabolism can reduce drug half-life and effectiveness.
Additionally, decreased gastrointestinal motility can enhance drug absorption, altering pharmacokinetics during pregnancy.
Q3 QUESTION 3 OF 244
Examples of medications that can be teratogenic
CORRECT ANSWER
Antiepileptic drugs, antimicrobials such as tetracyclines and fluoroquinolones, vitamin A in large doses, some anticoagulants, and hormonal medications such as
diethylstilbestrol (DES).
RATIONALE
Teratogenic medications disrupt normal fetal development, leading to congenital malformations; for instance, antiepileptic drugs can cause neural tube defects, while
tetracyclines may affect bone and tooth formation. Understanding these risks informs safe prescribing practices during pregnancy to mitigate potential harm to the
developing fetus.
Q4 QUESTION 4 OF 244
How is absorption of intramuscular medications different in neonates?
CORRECT ANSWER
slow and erratic due to low blood flow in muscles first few days of life
RATIONALE
Absorption of intramuscular medications in neonates is slow and erratic because their muscle tissue has reduced perfusion, resulting in lower blood flow during the first few
days of life. This altered pharmacokinetics necessitates careful consideration of dosage and timing to ensure therapeutic efficacy.
Q5 QUESTION 5 OF 244
Why is absorption of medication in the stomach increased in infancy?
CORRECT ANSWER
delayed gastric emptying
Page 2
, RATIONALE
Delayed gastric emptying in infants prolongs the time medications remain in the stomach, enhancing drug absorption by increasing the contact time with the gastric mucosa.
This physiological characteristic of infancy impacts pharmacokinetics, necessitating careful consideration in dosing and administration.
Q6 QUESTION 6 OF 244
Some medications that should be avoided in the pediatric patient?
CORRECT ANSWER
glucocorticoids, discoloration of developing teeth with tetracyclines, and kernicterus with sulfonamides, levofloxacin (antibiotics)
aspirin (Severe intoxication from acute overdose)
RATIONALE
Glucocorticoids can impair growth and immune function in children, while tetracyclines can lead to permanent tooth discoloration due to their affinity for calcium.
Additionally, sulfonamides may cause kernicterus by displacing bilirubin, and aspirin poses a risk of Reye's syndrome in pediatric patients, making these medications
contraindicated.
Q7 QUESTION 7 OF 244
Why do nitrates need to be taken no later than 4 PM?
CORRECT ANSWER
Need nitrate free interval so tolerance doesn't develop
RATIONALE
Nitrates require a nitrate-free interval to prevent the development of tolerance, which diminishes their effectiveness in managing angina. Administering them by 4 PM ensures
that the patient has sufficient time without nitrates before the next dose, optimizing therapeutic outcomes.
Q8 QUESTION 8 OF 244
Nine factors that impact outcome of medication?
CORRECT ANSWER
Gender and race
Genetics and pharmacogenomics
Variability in absorption
placebo effect
Tolerance
patho
age
bodyweight
RATIONALE
Individual factors such as gender, race, genetics, and age significantly influence pharmacokinetics and pharmacodynamics, affecting drug absorption, metabolism, and
therapeutic response. Additionally, physiological variables like body weight, tolerance, and the placebo effect further contribute to variability in medication outcomes,
underscoring the need for personalized approaches in pharmacotherapy.
Q9 QUESTION 9 OF 244
examples of opioid agonist-antagonist
CORRECT ANSWER
Buprenorphine, Pentazocine, Butorphanol, Nalbuphine
Page 3
, RATIONALE
Opioid agonist-antagonists, such as buprenorphine, pentazocine, butorphanol, and nalbuphine, activate opioid receptors to provide analgesia while simultaneously blocking
other receptors to mitigate the risk of dependence and respiratory depression. This unique pharmacological profile allows for effective pain management with a lower
potential for abuse compared to pure agonists.
Q10 QUESTION 10 OF 244
What type of analgesic for moderate to severe pain?
CORRECT ANSWER
opioids
RATIONALE
Opioids bind to specific receptors in the central nervous system, providing effective analgesia by altering the perception of pain and emotional response. Their potency and
efficacy in managing moderate to severe pain make them the preferred choice in clinical settings.
Q11 QUESTION 11 OF 244
How are patients initially exposed to opioids?
CORRECT ANSWER
either recreationally (illicitly) or in context of pain management in medical setting
RATIONALE
Opioid exposure typically occurs through illicit recreational use or legitimate medical prescriptions for pain management, illustrating the dual pathways that contribute to
both therapeutic use and potential misuse. Understanding these exposure routes is critical for addressing the opioid crisis and implementing effective prevention strategies.
Q12 QUESTION 12 OF 244
Medications best for HTN for patient who is pregnant?
CORRECT ANSWER
labetalol, methyldopa, nifedipine
RATIONALE
Labetalol, methyldopa, and nifedipine are preferred antihypertensives during pregnancy due to their safety profiles, effectiveness in managing hypertension, and minimal
adverse effects on fetal development. These medications help maintain maternal blood pressure while ensuring fetal well-being, aligning with guidelines for treating
hypertension in pregnant patients.
Q13 QUESTION 13 OF 244
ACE inhibitors MOA
CORRECT ANSWER
Angiotensin Converting Enzyme Inhibitors (ACE-I) prevent the conversion of angiotensin I to angiotensin II, which disrupts the renin-angiotensin-aldosterone system
(RAAS).
1. reduce levels of angiotensin II (through inhibition of ACE)
2. increasing levels of bradykinin (through inhibition of kinase 11)
