1. Which of the following is the primary site of activity for the drug Warfarin?
- A. Kidney
- B. Liver
- C. Blood
- D. Heart
Correct answer: B
Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.
2. Which of the following is classified as a class IA Sodium Channel blocker?
- A. Quinidine
- B. Disopyramide
- C. Aminodarone
- D. Propafenone
Correct answer: A
Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
3. A healthcare professional is preparing to administer an IV antibiotic to a client who has a systemic infection. Which of the following actions should the professional take first?
- A. Administer an antihistamine prior to the antibiotic.
- B. Monitor the client's urine output.
- C. Check the client's allergy history.
- D. Assess the client's vital signs.
Correct answer: C
Rationale: The first action the healthcare professional should take is to check the client's allergy history before administering the antibiotic to prevent a potential allergic reaction. It is crucial to identify any known allergies to antibiotics to ensure the client's safety and well-being. Administering an antihistamine prior to the antibiotic (Choice A) is not recommended unless an allergic reaction occurs. Monitoring the client's urine output (Choice B) and assessing the client's vital signs (Choice D) are important but not the first step in this situation. Checking the client's allergy history takes precedence to prevent adverse reactions.
4. Which of the following conditions are not treated with Barbiturates?
- A. Seizures
- B. Hypotension
- C. Insomnia
- D. Anxiety
Correct answer: B
Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.
5. A client is taking oral Oxycodone and Ibuprofen. The nurse should identify that an interaction between these two medications will cause which of the following findings?
- A. A decrease in serum levels of ibuprofen, possibly leading to a need for increased doses of this medication.
- B. A decrease in serum levels of oxycodone, possibly leading to a need for increased doses of this medication.
- C. An increase in the expected therapeutic effect of both medications.
- D. An increase in expected adverse effects for both medications.
Correct answer: C
Rationale: The interaction between oxycodone and ibuprofen results in an increase in the expected therapeutic effect of both medications. Oxycodone is a narcotic analgesic, while ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). They work through different mechanisms but complement each other in pain management. When taken together, they can enhance the pain-relieving effects of each other, providing better pain relief for the client.
