A 42-year-old man is brought to the emergency department with symptoms of acute alcohol withdrawal. He has a history of chronic alcohol abuse and reports his last drink was 32 hours ago. On examination, he appears agitated, diaphoretic, and tremulous. His vital signs show tachycardia and hypertension. The physician decides to initiate treatment with Lorazepam.
Which of the following best describes why Benzodiazepines are used to treat alcohol withdrawal?
They inhibit the metabolism of alcohol in the liver
They block the reuptake of dopamine in the central nervous system
They have no potential for abuse or dependence
They enhance the effects of GABA in the central nervous system
The Correct Answer is D
A. They inhibit the metabolism of alcohol in the liver: Benzodiazepines do not affect alcohol metabolism. Enzymes like alcohol dehydrogenase and aldehyde dehydrogenase are responsible for metabolizing alcohol, and benzodiazepines have no role in this process.
B. They block the reuptake of dopamine in the central nervous system: This mechanism is more characteristic of stimulant drugs like cocaine or certain antidepressants. Benzodiazepines act primarily on GABAergic pathways and do not target dopamine reuptake.
C. They have no potential for abuse or dependence: Benzodiazepines carry a well-documented risk of dependence and abuse, especially with long-term use or in individuals with a history of substance use disorders. Their use in alcohol withdrawal is carefully managed due to this risk.
D. They enhance the effects of GABA in the central nervous system: Benzodiazepines potentiate GABA, the brain’s primary inhibitory neurotransmitter, which helps to stabilize the CNS, reduce seizures, and manage agitation during alcohol withdrawal. This GABAergic action compensates for the decreased inhibitory tone seen in alcohol-dependent individuals during withdrawal.

Correct Answer is ["B","C","D"]
Explanation
A. Stop taking the medication if you experience any side effects: Patients should never discontinue antihypertensive medications without medical guidance. Some side effects may be temporary or manageable with adjustments, so it's important to consult the provider rather than stopping the drug abruptly.
B. Make lifestyle changes such as maintaining a healthy diet and exercising regularly: Lifestyle modifications are a key part of managing hypertension and improving cardiovascular health. Diet, weight management, and regular activity can enhance medication effectiveness and reduce long-term complications.
C. Monitor your blood pressure and heart rate regularly and keep a log of the readings: Routine self-monitoring allows early detection of abnormal trends and helps evaluate how well the medication is working. A log also assists healthcare providers in making informed treatment decisions and adjustments.
D. Change positions slowly to reduce the risk of dizziness and falls: Many antihypertensive drugs can cause orthostatic hypotension, especially when therapy begins. Standing up slowly from sitting or lying positions can prevent dizziness, fainting, and injury from accidental falls.
E. It's okay to skip doses occasionally if you feel your blood pressure is under control: Skipping doses undermines blood pressure stability and increases the risk of stroke, heart attack, or kidney damage. Medications must be taken regularly, even if symptoms are not noticeable.
Correct Answer is C
Explanation
A. Montelukast: This leukotriene receptor antagonist is used for long-term asthma control and prevention of exercise-induced bronchospasm. It is not effective for treating acute asthma attacks due to its delayed onset of action.
B. Salmeterol: This is a long-acting beta-2 agonist (LABA) used for maintenance therapy in asthma. It has a slower onset and should never be used for rapid symptom relief during an acute attack, as doing so can delay appropriate treatment.
C. Albuterol: Albuterol is a short-acting beta-2 agonist (SABA) that provides rapid bronchodilation and is the first-line rescue medication for aborting an acute asthma attack. It works within minutes to relieve bronchospasm and improve airflow.
D. Beclomethasone: This inhaled corticosteroid is used for long-term asthma management by reducing airway inflammation. It is not effective in acute situations because it does not provide immediate bronchodilation.
