Clinical Judgment
Question 1: A client diagnosed with major depressive disorder is prescribed
phenelzine. Which dietary instruction is most critical for the nurse to include
in the teaching plan?
A. Increase intake of high-fiber foods to prevent constipation.
B. Avoid foods containing tyramine, such as aged cheeses and cured meats.
C. Restrict fluid intake to prevent water intoxication.
D. Supplement the diet with potassium-rich foods.
CORRECT ANSWER: B. Avoid foods containing tyramine, such as aged cheeses
and cured meats.
Rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI). MAOIs block the
enzyme that breaks down tyramine, leading to a hypertensive crisis if tyramine-rich
foods are consumed. Options A, C, and D are not critical dietary instructions for this
medication.
Question 2: A client with schizophrenia is experiencing auditory
hallucinations. Which nursing intervention is most therapeutic?
A. Tell the client that the voices are not real and should be ignored.
B. Ask the client to describe the content of the hallucinations.
C. Encourage the client to listen to music to drown out the voices.
D. Reinforce reality and focus on the client's strengths.
CORRECT ANSWER: D. Reinforce reality and focus on the client's strengths.
Rationale: The most therapeutic approach is to reinforce reality without arguing with the
client's experience. Focusing on strengths helps the client feel supported. Asking to
describe the content may be appropriate for assessment but is not the primary
therapeutic intervention.
Question 3: A nurse is assessing a client with dementia. Which finding is a
manifestation of sundowning syndrome?
A. Increased confusion and agitation during the evening hours.
B. Excessive sleeping during the daytime.
C. Improved memory function after meals.
D. Consistent mood stability throughout the day.
,CORRECT ANSWER: A. Increased confusion and agitation during the evening
hours.
Rationale: Sundowning syndrome is characterized by a pattern of increased confusion,
agitation, and restlessness that typically begins in the late afternoon or evening. Options
B, C, and D are not indicative of this syndrome.
Question 4: A client is admitted with a diagnosis of antisocial personality
disorder. Which behavior is the nurse most likely to observe?
A. Extreme dependency and submissiveness.
B. Ritualistic behaviors and a need for order.
C. A lack of remorse and disregard for the rights of others.
D. Intense fear of abandonment and social rejection.
CORRECT ANSWER: C. A lack of remorse and disregard for the rights of
others.
Rationale: Antisocial personality disorder is characterized by a pervasive pattern of
disregard for and violation of the rights of others, often accompanied by a lack of
remorse. Options A, B, and D describe dependent, obsessive-compulsive, and borderline
personality disorders, respectively.
Question 5: A client is experiencing a severe panic attack. What is the priority
nursing action?
A. Teach the client deep breathing exercises.
B. Place the client in a quiet, non-stimulating environment.
C. Administer a prescribed PRN benzodiazepine.
D. Stay with the client and provide reassurance of safety.
CORRECT ANSWER: D. Stay with the client and provide reassurance of safety.
Rationale: The priority during a severe panic attack is to provide safety and support by
staying with the client. A quiet environment (B) and medication (C) are helpful but
secondary to providing immediate presence and reassurance.
Question 6: A client with bipolar disorder is in a manic phase. Which
intervention is most appropriate for managing nutrition?
A. Provide a low-calorie diet to manage weight gain.
B. Offer high-calorie, high-protein finger foods that can be eaten on the go.
C. Restrict snacks to scheduled meal times only.
D. Provide a high-fiber diet to prevent constipation.
CORRECT ANSWER: B. Offer high-calorie, high-protein finger foods that can be
eaten on the go.
Rationale: Clients in a manic phase are often hyperactive and may not sit for meals.
High-calorie, high-protein finger foods allow for adequate nutritional intake while
accommodating the client's need for movement.
,Question 7: A client is prescribed lithium carbonate. Which serum level
indicates toxicity?
A. 0.6 mEq/L
B. 0.8 mEq/L
C. 1.2 mEq/L
D. 1.8 mEq/L
CORRECT ANSWER: D. 1.8 mEq/L
Rationale: The therapeutic range for lithium is 0.6–1.2 mEq/L. A level of 1.8 mEq/L or
higher is considered toxic and requires immediate medical attention.
Question 8: A client with post-traumatic stress disorder (PTSD) is having a
flashback. What is the best nursing response?
A. "Tell me what you are seeing right now."
B. "You are safe here. Look around and tell me what you see."
C. "Let's discuss strategies to help you forget this event."
D. "Try to focus on the sounds you hear in the room."
CORRECT ANSWER: B. "You are safe here. Look around and tell me what you
see."
Rationale: During a flashback, the client is re-experiencing the traumatic event.
Grounding techniques that orient the client to the present environment are most
effective. Emphasizing safety and using sensory awareness helps the client regain
control.
Question 9: A nurse is caring for a client with bulimia nervosa. Which
electrolyte imbalance is of greatest concern?
A. Hypernatremia
B. Hyperkalemia
C. Hypokalemia
D. Hypermagnesemia
CORRECT ANSWER: C. Hypokalemia
Rationale: Clients with bulimia nervosa who self-induce vomiting lose potassium-rich
gastric contents, leading to hypokalemia. This can cause cardiac arrhythmias and is the
most life-threatening electrolyte imbalance in these clients.
Question 10: A client with obsessive-compulsive disorder (OCD) spends hours
checking locks. The nurse should recognize this behavior as a result of:
A. An attempt to gain control over anxiety.
B. A psychotic break with reality.
C. An intentional need to manipulate others.
D. A lack of impulse control.
, CORRECT ANSWER: A. An attempt to gain control over anxiety.
Rationale: Compulsive behaviors, such as repeated checking, are performed to
neutralize or reduce the anxiety caused by obsessive thoughts. The behavior is not
intentional manipulation or a psychotic symptom.
Question 11: A client has been taking paroxetine for 4 weeks and reports
feeling much better. What is the most important instruction for the nurse to
reinforce?
A. "You can stop the medication now that you feel better."
B. "Continue the medication as prescribed and do not stop abruptly."
C. "Take the medication only when you feel symptoms returning."
D. "Double the dose if you have a stressful day."
CORRECT ANSWER: B. "Continue the medication as prescribed and do not
stop abruptly."
Rationale: Paroxetine is a selective serotonin reuptake inhibitor (SSRI) that can cause
withdrawal symptoms if stopped abruptly. Clients must continue the medication even if
they feel better to maintain therapeutic levels and prevent relapse.
Question 12: A client with delirium is showing signs of agitation. Which
environmental intervention is most appropriate?
A. Provide a variety of activities to stimulate the client.
B. Use a low-stimulation environment with a well-lit room.
C. Encourage family members to stay around the clock.
D. Move the client to a room with multiple roommates for socialization.
CORRECT ANSWER: B. Use a low-stimulation environment with a well-lit
room.
Rationale: Delirium is exacerbated by sensory overload. A low-stimulation environment
that is well-lit (to reduce misperceptions) is most appropriate. Frequent family visits may
be overwhelming.
Question 13: A client with a history of alcoholism is admitted for
detoxification. The nurse should monitor for which symptom of alcohol
withdrawal?
A. Bradycardia and hypotension.
B. Seizures and tremors.
C. Hyperthermia and dry skin.
D. Hypotension and respiratory depression.
CORRECT ANSWER: B. Seizures and tremors.
Rationale: Alcohol withdrawal can cause autonomic hyperactivity, tremors, and seizures.
Symptoms typically begin 6–8 hours after the last drink. Bradycardia and hypotension
are not typical; tachycardia and hypertension are more common.
