A nurse is assessing a patient who has been receiving lorazepam (Ativan) for alcohol withdrawal symptoms. Which assessment finding would be most concerning and require immediate intervention?
1Patient reports mild nausea and has not eaten breakfast
2Respiratory rate of 8 breaths per minute with shallow breathing✓ 정답
3Patient appears drowsy but arouses easily to verbal stimuli
4Blood pressure of 140/90 mmHg with mild tremors in hands
해설
Respiratory rate of 8 breaths/min with shallow breathing indicates benzodiazepine-induced respiratory depression, a life-threatening adverse effect requiring immediate intervention. Other findings (nausea, drowsiness, hypertension with tremors) are common in alcohol withdrawal but not immediately life-threatening.
Clinical Judgment
This question assesses clinical judgment for patient safety during the management of alcohol withdrawal symptoms. The core is the ability to identify the most dangerous side effect of benzodiazepine (lorazepam) treatment and prioritize the finding that constitutes an immediate life threat among various assessment findings. Lorazepam stabilizes withdrawal symptoms but can cause excessive central nervous system depression. A respiratory rate of 8 breaths/min and shallow breathing are clear signs of respiratory depression, which can lead to oxygen deprivation and respiratory arrest, requiring immediate reporting and intervention (Notify HCP!). Other findings require monitoring but are not the most urgent risk in this situation.
Memory Tip:
The Big Risk to remember for benzodiazepines is Respiratory Depression. Associate it as "Benzos bring Breathing Down." When monitoring a patient with alcohol withdrawal, always apply the basic principles of Airway, Breathing, Circulation (ABC) first.
KR vs US:
In Korea, the CIWA (Clinical Institute Withdrawal Assessment for Alcohol) protocol is widely used for managing alcohol withdrawal patients, but the US NGN exam emphasizes the importance of independent nursing judgment regarding medication side effects even under this protocol. That is, even when administering medication according to the protocol, the patient's respiratory status is a primary responsibility area that the nurse must continuously assess and respond to immediately.

Clinical Practice Guide
When monitoring a patient with alcohol withdrawal who is receiving benzodiazepines such as lorazepam (Ativan), do the following:
1. Respiratory Monitoring: Regularly assess respiratory rate, depth, and pattern. Immediately report a respiratory rate of less than 12 breaths/min or signs of respiratory difficulty.
2. Level of Arousal: Assess for excessive sedation. A state of deep sleep with no response to stimuli is a danger sign.
3. Vital Signs: Track blood pressure, heart rate, and temperature along with the CIWA score.
4. Fall Prevention: Watch for ataxia and drowsiness due to the sedative effect and implement safety measures.
Caution:
In SATA (Select All That Apply) questions that ask for the "most concerning" finding or one that "requires immediate intervention," you often need to select the single finding that is directly life-threatening. Not all abnormal findings require 'immediate' intervention. Here, respiratory depression has a much higher priority than elevated blood pressure or mild nausea.
핵심 개념
Lorazepam — A benzodiazepine-class anxiolytic and sedative. It is widely used to manage alcohol withdrawal symptoms and works by acting on GABA receptors to depress the central nervous system.
Alcohol Withdrawal — A group of physiological and mental symptoms that occur when a person dependent on alcohol suddenly stops or reduces drinking. Symptoms may include agitation, tremors, sweating, tachycardia, hypertension, hallucinations, and seizures.
Respiratory Depression — A condition where the depth and frequency of breathing decrease inappropriately, leading to increased carbon dioxide levels and decreased oxygen levels in the blood. It is a major and life-threatening side effect of benzodiazepines and opioid medications.
Benzodiazepine — A class of drugs that act on GABA-A receptors to reduce neuronal excitability. They have anti-anxiety, sedative, muscle relaxant, and anticonvulsant effects. There is a risk of developing tolerance and dependence.
CIWA Protocol — Abbreviation for Clinical Institute Withdrawal Assessment for Alcohol. It is a standardized tool used to objectively evaluate the severity of alcohol withdrawal symptoms and adjust the dosage of medications such as benzodiazepines accordingly.
