Buspirone is:

Correct Answer: D

Rationale: Buspirone is classified as an anxiolytic drug, making option D the correct answer. Anxiolytic drugs are used to treat anxiety disorders by helping to reduce feelings of fear, tension, and nervousness without causing significant sedation or potential for abuse. Option A, sedative drug, is incorrect because buspirone does not exert sedative effects like traditional sedatives such as benzodiazepines. Option B, useful in insomnia, is incorrect as buspirone is not primarily indicated for the treatment of insomnia. Option C, rapid onset of action, is also incorrect as buspirone has a delayed onset of action compared to some other medications used for anxiety. Buspirone typically takes a few weeks to reach its full therapeutic effect, unlike medications with rapid onset like benzodiazepines. In an educational context, understanding the classification and specific effects of drugs like buspirone is crucial for nursing practice. Nurses need to be able to differentiate between various drug classes to provide safe and effective care to patients with anxiety disorders. Understanding the pharmacological properties of buspirone helps nurses in assessing its appropriate use and potential side effects, ultimately improving patient outcomes.

Correct Answer: B

Rationale: The correct answer is B) Pain of head injury. Morphine is not typically used for head injuries due to the concern of masking neurological changes that need to be monitored closely. A) Pain of myocardial infarction: Morphine is commonly used for relieving pain associated with myocardial infarction as it helps to reduce the workload on the heart by decreasing preload and afterload. C) Post operative abdominal pain: Morphine is frequently used for postoperative pain management, especially in cases of abdominal surgeries where pain can be severe. D) Acute pulmonary edema: Morphine can be used in cases of acute pulmonary edema to reduce anxiety and preload on the heart, which can help improve breathing and decrease the work of the heart. Educational context: Understanding the appropriate use of morphine is crucial for healthcare professionals to ensure safe and effective pain management for patients. Knowing the specific indications and contraindications of morphine can help prevent potential complications and ensure optimal patient care.

Correct Answer: D

Rationale: In this question, the correct answer is D) Oxazepam---- is a tricyclic antidepressant. Oxazepam is actually a benzodiazepine, not a tricyclic antidepressant. This is important to know because benzodiazepines like oxazepam are commonly used as anxiolytics, sedatives, and muscle relaxants, not as antidepressants. A) Buspirone is correctly paired as an antianxiety agent with negligible addictive liability. Buspirone is a non-benzodiazepine anxiolytic, and its unique mechanism of action makes it less likely to be associated with the risk of dependence and abuse compared to benzodiazepines. B) Alprazolam is correctly paired as a benzodiazepine with anxiolytic properties. It is not an antidepressant but rather primarily used to treat anxiety disorders. C) Baclofen is correctly paired with less sedation than diazepam. Baclofen is a muscle relaxant and antispasmodic agent commonly used to treat spasticity. It is known for causing less sedation compared to benzodiazepines like diazepam. Understanding these drug classifications and their respective properties is crucial for healthcare professionals, particularly nurses, who may administer these medications or educate patients about their uses and potential side effects. It is important to differentiate between drug classes to ensure safe and effective patient care.

Correct Answer: A

Rationale: Rationale: The correct answer is A) Aspirin. Aspirin has been associated with Reye's syndrome in children, a rare but serious condition characterized by swelling of the liver and brain. The use of aspirin in children with viral infections, such as influenza or chickenpox, has been linked to the development of Reye's syndrome. Acetaminophen (option B), ibuprofen (option C), and naproxen (option D) are not associated with Reye's syndrome. Acetaminophen is commonly used as a pain reliever and fever reducer, while ibuprofen and naproxen are nonsteroidal anti-inflammatory drugs (NSAIDs) used for pain relief and inflammation. Educationally, it is crucial for healthcare professionals to be aware of the association between aspirin and Reye's syndrome in children. This knowledge is essential for making informed decisions about the appropriate use of medications in pediatric patients. Understanding the risks and benefits of different drugs helps ensure safe and effective patient care. Nurses, pharmacists, and other healthcare providers must be able to identify drugs that may pose risks to specific patient populations, such as children vulnerable to Reye's syndrome.

Correct Answer: C

Rationale: In this question, the correct answer is C) Mu receptor-----respiratory depression. Explanation of why the correct answer is right: Mu receptors are primarily responsible for the analgesic effects of opioids. When opioids bind to Mu receptors in the central nervous system, they can cause respiratory depression by decreasing the drive to breathe, leading to slower and shallower breathing. This is a significant side effect of opioid use and is a critical consideration in clinical practice. Explanation of why the other options are wrong: A) Mu receptor-----dysphoria: Dysphoria is more commonly associated with Kappa receptor activation, not Mu receptors. B) Kappa receptor-----euphoria: Euphoria is often linked to Mu receptor activation, not Kappa receptors. D) Delta receptor-----dysphoria: Dysphoria is indeed associated with Kappa receptors rather than Delta receptors. Educational context: Understanding the specific actions of different opioid receptors is crucial for healthcare professionals, especially when prescribing or administering opioids. Knowing which receptors are responsible for certain effects helps in predicting and managing potential side effects and adverse reactions. This knowledge is vital in providing safe and effective care to patients, particularly in pain management and addiction treatment settings.
