Question 1 of 5
Which is not one of the rights of medication administration?
Correct Answer: C
Rationale: The five rights of medication administration are: the right patient, the right drug, the right dose, the right route, and the right time. These are essential principles to ensure safe and effective medication administration. The attitude of the healthcare provider is important for delivering care, but it is not included as one of the fundamental rights of medication administration. It is important for healthcare providers to approach medication administration with professionalism, compassion, and attentiveness, but it is not considered one of the primary rights in the context of medication administration protocols.
Question 2 of 5
Drug X has a median lethal dose of 30 mg and a median effective dose of 10. Drug Y has a therapeutic index of 4, while drug Z has a therapeutic index of 3. Which statement is accurate based on this information?
Correct Answer: C
Rationale: Therapeutic index (TI) = lethal dose (LD50) / effective dose (ED50). Drug X: 30/10 = 3. Drug Y: TI = 4. Drug Z: TI = 3. Higher TI means safer-Drug Y (4) tops X and Z (3), balancing efficacy and toxicity best. X and Y aren't both safer-X matches Z. X's TI isn't 20. Z isn't safest. Y's TI makes it safest.
Question 3 of 5
The nurse is to administer enteral medications to a patient who cannot swallow and is receiving continuous enteral feedings. Which is correct concerning administration of the enteral medications?
Correct Answer: B
Rationale: Liquid medications should be diluted before administration through a feeding tube to prevent clogging and ensure proper absorption. Adding medications to the enteral solution (A) is not recommended, as it can alter the formula's composition and stability.
Question 4 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Intravenous nitroglycerin is commonly administered in infusions along with other medications, such as heparin and morphine, to manage acute myocardial infarction. By giving it in infusions, healthcare providers can control the dosage and titrate it to the patient's response while also minimizing the risk of sudden drops in blood pressure. Additionally, administering nitroglycerin in infusions allows for precise and continuous delivery of the medication to achieve the desired therapeutic effect.
Question 5 of 5
A nurse is caring for a client who is receiving cyclobenzaprine hydrochloride (Flexeril) for the treatment of muscle spasm. Which of the following medical conditions is contraindicated with the use of the medication?
Correct Answer: B
Rationale: Cyclobenzaprine, a muscle relaxant, has anticholinergic effects that can exacerbate angle-closure glaucoma by increasing intraocular pressure. It is contraindicated in patients with this condition. While it may cause dry mouth or urinary retention, it is not specifically contraindicated in diabetes, emphysema, or urinary tract infections. The anticholinergic properties of cyclobenzaprine make it unsuitable for patients with angle-closure glaucoma.
