ATI LPN Mental Health Exam IV Questions
Extract:
Question 1 of 5
A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L. The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Correct Answer: B
Rationale: Hyperkalemia (6.8 mEq/L, normal 3.5–5.0 mEq/L) from spironolactone (a potassium-sparing diuretic) risks cardiac arrhythmias. A 12-lead ECG detects changes (e.g., peaked T waves). ESR is unrelated, more potassium worsens hyperkalemia, and fluid restriction doesn’t address potassium levels. ECG is urgent for cardiac monitoring.
Question 2 of 5
Which of the following is a common characteristic of an abuser?
Correct Answer: D
Rationale: Secure with self: Abusers are often insecure and may have low self-esteem. They may project a false sense of confidence but are not truly secure with themselves. Blames self for own problems: Abusers typically blame others for their problems and take little responsibility for their actions. Control of emotions: Abusers often have poor control of their emotions, leading to aggressive and violent behaviors. History of substance abuse: Substance abuse is commonly found in the history of abusers. It can exacerbate abusive behavior and reduce impulse control.
Question 3 of 5
Which of the following is an impulse control disorder?
Correct Answer: D
Rationale: Deceitfulness: Deceitfulness is more associated with antisocial personality disorder rather than impulse control disorders. Aggressive conduct: Aggressive conduct is associated with conduct disorder, not specifically with impulse control disorders. Serious rule violations: Serious rule violations are characteristic of conduct disorder. Pyromania: Pyromania is an impulse control disorder characterized by the recurrent urge to set fires.
Question 4 of 5
A teenager is noted to have a heightened awareness of reality, feelings of depersonalization, unpredictable and sometimes violent behavior, and flashbacks. The nurse suspects that the teenager is taking which of the following chemicals?
Correct Answer: D
Rationale: Cannabis: While cannabis can alter perception and cause depersonalization, it is less likely to cause violent behavior and flashbacks. Heroin: Heroin is a depressant that typically causes sedation and euphoria, not heightened awareness or violent behavior. Cocaine: Cocaine is a stimulant that can cause heightened awareness but is less associated with depersonalization and flashbacks. Phencyclidine (PCP): PCP is known to cause severe alterations in perception, depersonalization, unpredictable and violent behavior, and flashbacks.
Question 5 of 5
A nurse is reinforcing discharge teaching for a client who will be taking warfarin (Coumadin) at home. Which of the following statements indicates that the client understands the effects of this medication?
Correct Answer: B
Rationale: Warfarin, an anticoagulant, increases bleeding risk. Avoiding aspirin (also a blood thinner) prevents excessive anticoagulation, showing understanding. High vitamin K intake counteracts warfarin by aiding clotting factor synthesis. Alcohol increases bleeding risk, and while electric razors reduce cuts, this isn’t specific to warfarin’s effects but a safety measure.
