A teenager who has a history of alcohol abuse wants to host a holiday party at his home. In order to best implement family-based measures to prevent the use of alcohol or drugs the parents will:
- A. Refuse to allow the teenager to host the party.
- B. Insist upon being home and visible to the guests during the party.
- C. Allow the party only if it is held at a public space such as a church recreation room.
- D. Have all those attending sign a contract promising not to drink or use drugs during the party.
Correct Answer: B
Rationale: The correct answer is B because by insisting on being home and visible during the party, the parents can actively supervise and monitor the activities, deterring any alcohol or drug use. They can intervene promptly if any issues arise.
A: Refusing to allow the teenager to host the party may lead to rebellion and secretive behavior.
C: Allowing the party in a public space does not guarantee supervision or control over alcohol/drug use.
D: Having attendees sign a contract relies solely on their compliance without active supervision or monitoring.
Why are cardiovascular medications, such as beta blockers and alpha-2 receptor agonists, used in patients with anxiety?
- A. Block manifestations: Tremors
- B. Palpitations
- C. Tachycardia
- D. Sweating
Correct Answer: A
Rationale: The correct answer is A: Block manifestations: Tremors. Beta blockers and alpha-2 receptor agonists are used in patients with anxiety to block physical manifestations such as tremors. Beta blockers reduce the physical symptoms of anxiety by blocking the effects of adrenaline on the body, including tremors. Alpha-2 receptor agonists also help reduce physical symptoms by decreasing the release of norepinephrine. Palpitations (B), tachycardia (C), and sweating (D) are also physical symptoms of anxiety, but beta blockers and alpha-2 receptor agonists primarily target tremors in this context.

A nurse is called to the home of a neighbor and finds an unconscious person still holding a medication bottle labeled pentobarbital sodium. What is the nurse’s first action?
- A. Test reflexes
- B. Check pupils
- C. Initiate vomiting
- D. Establish a patent airway
Correct Answer: D
Rationale: The correct answer is D: Establish a patent airway. The first action in any emergency situation involving an unconscious person is to ensure their airway is open and clear to facilitate breathing. This is crucial for maintaining oxygenation and preventing potential complications like hypoxia. Testing reflexes (A) and checking pupils (B) are important assessments but not the immediate priority in this situation. Initiating vomiting (C) is contraindicated as it can lead to further complications, especially if the person has ingested a potentially harmful substance.
Select the most appropriate outcome for a patient completing the fourth alcohol detoxification program in 1 year. Before discharge, the patient will
- A. use rationalization in healthy ways.
- B. state, 'I see the need for ongoing treatment.'
- C. identify constructive outlets for expression of anger.
- D. develop a trusting relationship with one staff member.
Correct Answer: B
Rationale: The correct answer is B because stating 'I see the need for ongoing treatment' demonstrates insight and willingness to engage in further treatment, indicating a readiness for change. This is crucial for someone who has completed multiple detox programs in a short period. Choice A (using rationalization in healthy ways) may not address the underlying issues leading to repeated detox programs. Choice C (identifying constructive outlets for expression of anger) is important but not the most urgent concern after detox. Choice D (developing a trusting relationship with one staff member) is beneficial but does not address the need for ongoing treatment.
