Question 1 of 5
What route is Amlodipine taken?
Correct Answer: A
Rationale: Amlodipine is a medication that is taken orally, usually in the form of tablets. The abbreviation "PO" stands for per os, which means by mouth or orally. Amlodipine is widely prescribed to treat high blood pressure and certain types of chest pain. It works by relaxing the blood vessels, making it easier for the heart to pump blood. Taking amlodipine orally allows it to be absorbed through the digestive system and enter the bloodstream to exert its therapeutic effects.
Question 2 of 5
Which of the following is NOT a site for drug metabolism:
Correct Answer: D
Rationale: The placenta is not a site for drug metabolism. Drug metabolism primarily occurs in the liver, gastrointestinal tract (GIT), skin, and kidney. The placenta serves as a barrier between the mother and fetus and is involved in nutrient and waste exchange but does not play a significant role in drug metabolism processes.
Question 3 of 5
The ulcerogenic properties of aspirin is caused by the following, except
Correct Answer: B
Rationale: The ulcerogenic properties of aspirin are primarily caused by the inhibition of prostaglandin synthesis, particularly through the inhibition of the enzyme cyclooxygenase-1 (Cox-1). Prostaglandins play a crucial role in maintaining the protective mucus barrier in the stomach lining. When prostaglandin synthesis is inhibited, this protective barrier is compromised, leading to increased susceptibility to damage from the acidic gastric environment. The drug's acidity itself (Choice A), by irritating the stomach lining, can contribute to ulcer formation. Thromboxane inhibition (Choice B) is not directly related to the ulcerogenic properties of aspirin but is more associated with the drug's antiplatelet effects. Cox-1 inhibition (Choice D) is a key factor in aspirin-induced gastrointestinal injury as it disrupts the normal mucosal defense mechanisms.
Question 4 of 5
A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?
Correct Answer: D
Rationale: St. John's wort is an herbal supplement that can interact with many medications, including venlafaxine (Effexor). When taken together, it can decrease the effectiveness of venlafaxine by increasing its metabolism, potentially leading to reduced therapeutic effects. This interaction can also increase the risk of side effects or adverse reactions. Therefore, the nurse should be concerned about the ingestion of St. John's wort when a patient is taking venlafaxine to ensure proper medication management and effectiveness. It is important for patients to inform healthcare providers about all supplements they are taking to prevent harmful interactions.
Question 5 of 5
Which activity has a higher priority for the nurse to advise the patient to avoid while taking ixazomib?
Correct Answer: C
Rationale: Ixazomib, a proteasome inhibitor, can cause myelosuppression, increasing the risk of infections. Patients should be advised to avoid crowds and individuals who are ill to reduce exposure to infectious agents. While alcohol and aspirin may interact with other medications, they are not specifically contraindicated with ixazomib. Taking the drug on an empty stomach is not required, as it can be taken with or without food. Preventing infections is the highest priority due to the drug's impact on the immune system.
