Question 1 of 5
What is one therapeutic use for Nitroglycerine?
Correct Answer: A
Rationale: Nitroglycerine is commonly used as a therapeutic agent for the relief or prevention of anginal attacks in patients with stable angina or chronic angina pectoris. Angina is a condition characterized by chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. Nitroglycerine works by dilating blood vessels, which helps to increase blood flow to the heart and reduce the workload of the heart, thereby relieving chest pain associated with angina.
Question 2 of 5
A 44-year-old man with acute lymphocytic leukemia is undergoing a multiagent chemotherapy protocol. Agents used include methotrexate. The cycle of medication will last 6 weeks. Which of the following tissues is most likely to experience toxic effects as a result of this therapy?
Correct Answer: A
Rationale: Methotrexate targets rapidly dividing cells. Buccal mucosa , with high turnover, is most vulnerable, causing mucositis. Bones (B, D) and skin are less affected. Teeth (E) aren't primary. This toxicity reflects methotrexate's antimetabolite action in ALL.
Question 3 of 5
The client is receiving a very expensive medication. The client asks the nurse why the medicine is so expensive. What is the best response by the nurse?
Correct Answer: C
Rationale: High drug costs stem from research, development, and production expenses-years of trials and manufacturing-requiring companies to recover investments, a factual explanation. Insurance coverage sidesteps the question. Advertising adds cost but isn't primary. Accountability is opinion, not answer. Development costs provide a clear, neutral reason, educating the client on pharmaceutical economics.
Question 4 of 5
The pregnant patient plans to breastfeed her baby. She asks the nurse about the use of herbal products during breastfeeding. What is the best response by the nurse?
Correct Answer: B
Rationale: Herbals (e.g., St. John's wort) transfer to breast milk, risking infant effects (e.g., sedation), so avoiding them is safest, per pharmacokinetics. Labels lack consistent breastfeeding data. ‘Natural' doesn't mean safe-some are toxic. Timing doesn't eliminate transfer. Transfer risk advises caution, protecting the baby.
Question 5 of 5
A patient is about to receive a morning dose of digoxin and has an apical pulse of 53 beats/minute. Which of the following actions should the nurse do first?
Correct Answer: A
Rationale: Digoxin should be withheld if the apical pulse is below 60 beats/minute in adults, as it can exacerbate bradycardia and lead to serious cardiac complications. The nurse should hold the dose and notify the healthcare provider for further instructions. Administering the dose (B) or contacting the charge nurse (C) without holding the dose is inappropriate.
