Correct Answer: A

Rationale: A 12-lead ECG requires electrode placement on the chest and limbs to record heart activity, making this the key instruction. Remaining still (
B) and short duration (
D) are true but secondary. Slight pressure (
C) may occur, but it’s not the primary focus. Electrode placement is procedural core.

Correct Answer: A

Rationale: Planning to give his CD collection to his girlfriend: Giving away prized possessions is a common warning sign of suicidal intent, indicating that the person is preparing for their absence. Preferring to eat his meals while watching TV: This behavior is relatively normal and does not necessarily indicate suicidal intent. Stating that he wants to be with his peers more than with his parents: Wanting to spend time with peers is typical for adolescents and does not specifically indicate suicidal intent. Telling his parents that he doesn't want to talk about the attempt: Not wanting to discuss the attempt could be due to embarrassment, guilt, or other reasons, but it is not as direct an indicator of ongoing suicidal intent as giving away possessions.

Correct Answer: B

Rationale: Increased body temperature: Alcohol consumption typically causes vasodilation, which can lead to a decrease in body temperature, not an increase. Cardiac dysrhythmias: Large amounts of alcohol can affect the heart's electrical system, leading to cardiac dysrhythmias. Hypotension: Alcohol is a vasodilator, which can lead to a drop in blood pressure (hypotension). Bradycardia: Alcohol typically causes tachycardia (increased heart rate), not bradycardia (decreased heart rate).

Correct Answer: B

Rationale: Facilitate time alone for the client. Allowing time alone is not appropriate for a suicidal client as it increases the risk of self-harm. Make a no self-harm contract. A no self-harm contract can be part of a suicide prevention plan, where the client agrees to not harm themselves and to seek help if they feel the urge to do so. Administer antianxiety medication: While medication can help with anxiety, it is not a primary intervention for immediate suicide prevention. Prevent family/friend visitation for 48 hours: Preventing visitation can increase feelings of isolation and is not an appropriate intervention for suicide prevention.

Correct Answer: C

Rationale: Bradycardia (<60 BPM) reduces cardiac output, impairing cerebral perfusion and causing lightheadedness. Volume deficit may cause tachycardia, not bradycardia. Anxiety typically increases heart rate. Fever raises heart rate to meet metabolic demand, not lowers it. Lightheadedness reflects inadequate brain oxygenation.
