Which is not one of the rights of medication administration?

Correct Answer: C

Rationale: The rights of medication administration include the right patient, right medication, right dose, right route, right time, and right documentation. However, "right attitude" is not one of the recognized rights of medication administration. While having a positive and professional attitude is important for healthcare providers, it is not specifically listed as a distinct right in medication administration protocols.

Correct Answer: B

Rationale: Finasteride (Proscar), a 5-alpha reductase inhibitor, shrinks the prostate in BPH by reducing dihydrotestosterone, easing urinary obstruction. Smooth muscle relaxation is for ED drugs like sildenafil. It lowers DHT, not testosterone, and doesn't stimulate RNA synthesis. Prostate shrinkage is its core action, distinct from other mechanisms.

Correct Answer: C

Rationale: Neonates have an immature blood-brain barrier, increasing opioid penetration, not blocking it, so that's false. Spinal analgesia involves mu, delta, and kappa receptors, not just one type, making that false. Depressed CO2 response is the most reliable sign of opioid-induced respiratory depression, a true statement, reflecting medullary suppression. Tolerance to miosis develops minimally, unlike analgesia, so that's false. Addison's patients are hypersensitive to opioids due to cortisol lack. The CO2 response is a key monitoring parameter in opioid overdose.

Correct Answer: C

Rationale: Enterohepatic cycling refers to the process where drugs excreted into bile are delivered to the intestines and then reabsorbed into the bloodstream. This recycling can prolong the drug's presence in the body and its therapeutic effects. Hepatic clearance and total clearance refer to the liver's ability to remove drugs from the bloodstream, while the first-pass effect involves the metabolism of drugs before they reach systemic circulation. Enterohepatic cycling is a unique mechanism that impacts drug pharmacokinetics.
