Question 1 of 5
A patient taking a benzodiazepine says to the nurse, “I really like this pill because if I just take an extra one when I get really anxious, I always feel a lot better.” What is the nurse’s best response?
Correct Answer: B
Rationale: The correct answer is B because it acknowledges the patient's behavior, educates them on proper medication usage, and reinforces the importance of coping measures. By reviewing the medication usage and suggesting coping strategies, the nurse promotes patient education and empowerment. Choice A is incorrect as it immediately suggests changing medication without addressing the patient's misuse behavior. Choice C uses accusatory language and may lead to patient defensiveness. Choice D is not as effective as B in educating the patient on proper medication use and coping strategies.
Question 2 of 5
The nurse is reviewing medications used for depression. Which of these statements is a reason that selective serotonin reuptake inhibitors (SSRIs) are more widely prescribed today than tricyclic antidepressants?
Correct Answer: C
Rationale: The correct answer is C: Tricyclic antidepressants cause serious cardiac dysrhythmias if an overdose occurs. Tricyclic antidepressants have a narrow therapeutic index, meaning that even a small overdose can lead to severe toxicity, including cardiac dysrhythmias that can be life-threatening. This risk of overdose toxicity is a significant concern with tricyclic antidepressants and contributes to their decreased use compared to SSRIs. A: SSRIs having fewer sexual side effects is not the primary reason for their wider use compared to tricyclic antidepressants. While this may be a consideration for some patients, it is not the main factor influencing prescribing patterns. B: Drug-food interactions are indeed a concern with tricyclic antidepressants, but it is not the primary reason why SSRIs are more widely prescribed today. While SSRIs may have a lower risk of drug-food interactions, it is not the main driving factor behind their increased use. D: While SSRIs may have
Question 3 of 5
The nurse is preparing to administer adenosine (Adenocard) to a patient who is experiencing an acute episode of paroxysmal supraventricular tachycardia. When giving this medication, which is important to remember?
Correct Answer: C
Rationale: The correct answer is C. After administering adenosine, asystole may occur for a few seconds due to its rapid action on the heart's conduction system. Here's the rationale: 1. Adenosine works by slowing down conduction through the AV node, interrupting reentry pathways causing tachycardia. 2. This brief pause in electrical activity can cause a temporary stop in the heart's pumping action, resulting in asystole. 3. Asystole is expected and normal after adenosine administration, as it helps reset the heart's electrical activity and may terminate the tachycardia. In contrast, options A and D are incorrect because adenosine has a rapid onset of action within seconds and a very short half-life of less than 10 seconds, leading to a quick duration of action. Option B is incorrect as adenosine should be given as a rapid IV push to ensure its effectiveness.
Question 4 of 5
A patient asks the nurse about the uses of echinacea. Which use will the nurse include in the response?
Correct Answer: B
Rationale: The correct answer is B: Boosting the immune system. Echinacea is commonly used for its immune-boosting properties due to its ability to stimulate the immune system. It can help the body fight off infections and illnesses. Rationale: 1. Echinacea has been traditionally used for its immune-enhancing effects. 2. Research studies have shown that echinacea can increase the production of white blood cells, which are crucial for fighting infections. 3. Echinacea is often recommended to shorten the duration of colds and flu by supporting the immune response. 4. Memory enhancement (A), improving mood (C), and promoting relaxation (D) are not commonly associated with echinacea use based on scientific evidence.
Question 5 of 5
Intravenous injections are more suitable for oily solutions:
Correct Answer: B
Rationale: The correct answer is B: FALSE. Intravenous injections are not suitable for oily solutions due to the risk of causing pulmonary embolism or other serious complications. Oily solutions can lead to blockages in the blood vessels, posing significant health risks. Other choices are incorrect because intravenous injections should not be used for all oily solutions (Choice C) or none of them (Choice D) due to the potential harm they can cause.
