HESI Mental Health Practice Exam
1. An adolescent who attempted suicide with a drug overdose arrives in the emergency department with an empty 30-tablet bottle of acetaminophen (Tylenol). Which action should the nurse implement?
- A. Administer acetylcysteine (Mucomyst).
- B. Monitor cardiac rhythm for flat T waves.
- C. Check both serum AST and ALT levels.
- D. Prepare to administer Syrup of Ipecac.
Correct answer: A
Rationale: The correct action for the nurse to implement is to administer acetylcysteine (Mucomyst). Acetylcysteine is the antidote for acetaminophen overdose and should be administered promptly to prevent liver damage. Monitoring cardiac rhythm for flat T waves (Choice B) is not specific to acetaminophen overdose and is more related to cardiac conditions. Checking serum AST and ALT levels (Choice C) may be done later but is not the initial priority in this situation. Similarly, preparing to administer Syrup of Ipecac (Choice D) is not recommended anymore in cases of overdose as it can cause more harm.
2. Which action should the nurse implement first for a client experiencing alcohol withdrawal?
- A. Apply vest or extremity restraints.
- B. Give an alpha-adrenergic blocker.
- C. Provide a diet high in protein and calories.
- D. Prepare the environment to prevent self-injury.
Correct answer: D
Rationale: The correct action for the nurse to implement first for a client experiencing alcohol withdrawal is to prepare the environment to prevent self-injury. Clients undergoing alcohol withdrawal are at risk of seizures and other symptoms that may lead to self-harm. By ensuring a safe environment, the nurse can mitigate the risk of injury. Applying restraints (Choice A) should only be considered if less restrictive measures fail, as restraints can agitate the client further. Giving an alpha-adrenergic blocker (Choice B) may be part of the treatment plan for alcohol withdrawal but is not the first action to take. Providing a diet high in protein and calories (Choice C) is important for overall health but is not the priority when addressing immediate safety concerns.
3. A client with depression is prescribed an SSRI. The client asks, 'Why do I need to take this medication every day?' What is the best response by the nurse?
- A. This medication will help balance the chemicals in your brain.
- B. This medication needs to be taken regularly to be effective.
- C. This medication will start working immediately to improve your mood.
- D. You should take this medication only when you feel sad or depressed.
Correct answer: D
Rationale: Explaining that the medication may take several weeks to take full effect helps manage the client's expectations and encourages adherence to the prescribed treatment.
4. The RN is providing education about strategies for a safety plan for a female client who is a victim of intimate partner violence. Which strategies should be included in the safety plan? (select one that does not apply)
- A. Purchase a gun to use for protection.
- B. Keep quiet and calm.
- C. Take a self-defense course that retaliates against the abuser with injury.
- D. Have a bag ready that has extra clothes for self and children.
Correct answer: C
Rationale: Taking a self-defense course that retaliates against the abuser with injury can escalate the level of violence and is not recommended in a safety plan for a victim of intimate partner violence. The correct strategies include establishing a code, having a bag ready, and planning an escape route, which enhance safety without increasing the risk of harm.
5. A teenaged client, a heroin addict, is admitted to the unit for detoxification. What intervention is most important for the nurse to initiate during the first 24 hours after admission?
- A. Assign the client to a teen support group.
- B. Assess intake and output.
- C. Monitor for wheezing and apnea.
- D. Limit visitors to family members only.
Correct answer: B
Rationale: Assessing intake and output is crucial during the first 24 hours after admission for detoxification. This helps the nurse monitor the client's hydration status and kidney function as the body goes through withdrawal from heroin. Option A is incorrect because joining a support group is beneficial but may not be the priority in the initial phase of detoxification. Option C, monitoring for wheezing and apnea, is important but not the most critical intervention during the first 24 hours. Option D, limiting visitors to family members only, is not directly related to the immediate needs of assessing intake and output.
