The primary organ for drug elimination is the:
- A. Skin
- B. Lung(s)
- C. Kidney(s)
- D. Liver
Correct Answer: C
Rationale: The kidneys are the primary organ for drug elimination, excreting most drugs or their metabolites in urine.
A client is given an opiate drug for pain relief following general anesthesia. The client becomes extremely somnolent with respiratory depression. The physician is likely to order the administration of:
- A. naloxone (Narcan)
- B. labetalol (Normodyne)
- C. neostigmine (Prostigmin)
- D. thiothixene (Navane)
Correct Answer: A
Rationale: Naloxone reverses opioid-induced respiratory depression and somnolence by antagonizing opioid receptors. The other drugs do not address opioid overdose.
A client is given an opiate drug for pain relief following general anesthesia. The client becomes extremely somnolent with respiratory depression. The physician is likely to order the administration of:
- A. naloxone (Narcan).
- B. labetalol (Normodyne).
- C. neostigmine (Prostigmin).
- D. thiothixene (Navane).
Correct Answer: A
Rationale: Naloxone is an opiate antagonist. It attaches to opiate receptors and blocks or reverses the action of narcotic analgesics. Choice 2 is incorrect because Labetalol is a beta blocker. Choice 3 is incorrect because Neostigmine is an anticholinesterase agent. Choice 4 is incorrect because Thiothixene is an antipsychotic agent.
Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug might be absorbed. This process is known as:
- A. hepatic clearance.
- B. total clearance.
- C. enterohepatic cycling.
- D. first-pass effect.
Correct Answer: C
Rationale: Drugs and drug metabolites with molecular weights higher than 300 can be excreted via the bile, stored in the gallbladder, delivered to the intestines by the bile duct, and then reabsorbed into the circulation. This process reduces the elimination of drugs and prolongs their half-life and duration of action in the body. Hepatic clearance is the amount of drug eliminated by the liver. Total clearance is the sum of all types of clearance including renal, hepatic, and respiratory. First-pass effect is the amount of drug absorbed from the GI tract, then metabolized by the liver (reducing the amount of drug that makes it into circulation).
A diet high in fiber content can help an individual to:
- A. lose body weight fast.
- B. reduce diabetic ketoacidosis.
