HESI NSG Mental Health Nursing (Exam 1)

Correct Answer:  Systematic desensitization

Explanation 

Systematic desensitization is a behavioral therapy used to treat phobias and anxiety disorders by gradually exposing the patient to the feared object or situation in a controlled and manageable way. The patient learns relaxation techniques and progresses through increasingly challenging situations (e.g., imagining driving, sitting in a parked car, driving in an empty lot, then driving on the road). This method helps reduce fear and avoidance behaviors over time.

Explanation of Incorrect Answers:

Assertiveness training

Assertiveness training is used for patients who struggle with setting boundaries or expressing their needs. It does not address the irrational fear and avoidance behaviors seen in phobias.

Biofeedback

Biofeedback helps patients gain awareness and control over physiological responses (e.g., heart rate, muscle tension) to stress. While it can be useful for general anxiety, it does not directly target phobias or avoidance behaviors.

Stress management assistance

Stress management techniques (e.g., deep breathing, mindfulness) help patients cope with daily stress but do not systematically reduce phobic fear. They may complement therapy but are not the primary treatment for a debilitating phobia.

Summary:

For intense phobias that disrupt daily life, systematic desensitization is the most effective treatment. It gradually exposes the patient to the feared activity while using relaxation techniques to reduce anxiety. Other methods, like biofeedback and stress management, may help but do not directly target phobic avoidance.

The correct answer is: a. most members are caucasian

Explanation:

Group norms are the explicit or implicit rules that guide behavior within a group. They help establish expectations and maintain order.

b. No cell phone use during the group → This is a behavioral expectation, making it a group norm.

c. Be respectful of different opinions → This is a social guideline that fosters a supportive environment, making it a norm.

d. Allow opportunities for all to speak → This promotes equal participation, a key norm in group settings.

However, "most members are Caucasian" is simply a demographic characteristic, not a behavioral rule or expectation. Group norms are about behaviors, not group composition.

Summary:

A group norm is a rule or expectation that guides behavior within the group. Demographics (such as race, gender, or age) do not define norms. Hence, option A is NOT an example of a group norm.

Correct Answer: a. Disturbed sensory perception related to narrowed perceptual field

Explanation:

Severe anxiety is characterized by a greatly narrowed perceptual field, meaning the patient may struggle to focus, process information, or be aware of their surroundings. This impairment can lead to distorted perceptions, making “Disturbed sensory perception related to narrowed perceptual field” the most accurate nursing diagnosis for directing care.

Why the Other Options Are Incorrect:

b. Risk for injury related to closed perception – Incorrect. While perception is affected, the term “closed perception” is not a recognized clinical term. Additionally, risk for injury would apply more to conditions like delirium or unsteady gait, not directly to anxiety.

c. Hopelessness related to total loss of control – Incorrect. Hopelessness is more associated with depression, not anxiety. Severe anxiety may cause a sense of loss of control, but it does not typically lead to hopelessness unless there is an underlying depressive disorder.

d. Risk for other-directed violence related to combative behavior – Incorrect. Patients with severe anxiety are more likely to experience internal distress rather than aggression toward others. This diagnosis would be more appropriate for psychotic disorders or impulse control disorders.

Summary:

Severe anxiety significantly narrows the perceptual field, leading to distorted sensory processing. Therefore, option A is the most appropriate nursing diagnosis for guiding patient care.

Correct Answer: c. The thoughts, images, and impulses tend to worsen with stress.

Explanation:

Obsessive-compulsive disorder (OCD) is an anxiety-related disorder where individuals experience intrusive, distressing thoughts (obsessions) and feel compelled to engage in repetitive behaviors (compulsions) to reduce anxiety. Stress is a major trigger that can intensify OCD symptoms, making obsessions more frequent and compulsions more difficult to resist. Educating the family about this connection can help them provide appropriate support during stressful times.

Why the Other Options Are Incorrect:

a. The thoughts, images, and impulses are voluntary. – Incorrect. OCD thoughts and compulsions are involuntary and uncontrollable; individuals do not choose to have them.

b. The family should pay immediate attention to symptoms. – Incorrect. While support is essential, excessive attention to symptoms can reinforce compulsions and make the disorder worse. Instead, families should encourage treatment adherence and provide a supportive, nonjudgmental environment.

d. OCD is a chronic disorder that does not respond to treatment. – Incorrect. While OCD can be chronic, it does respond to treatment, including cognitive-behavioral therapy (CBT), exposure and response prevention (ERP), and medications like SSRIs. Many individuals experience significant improvement with proper treatment.

Summary:

OCD worsens under stress, so educating the family about stress management and appropriate support is essential. Option C is correct because it addresses a key factor in managing OCD symptoms effectively.

Correct Answer:  Collaborate with the patient to reduce the amount of time they engage in ritualistic behavior.

Explanation

Obsessive-compulsive disorder (OCD) is characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions) performed to reduce anxiety. The best approach is to gradually help the patient reduce the frequency and duration of compulsions, rather than abruptly stopping them. Collaborative planning allows the patient to develop coping strategies and feel a sense of control over their progress. Example: The nurse might suggest delaying handwashing for a few minutes or reducing the duration slightly, building toward gradual exposure therapy.

Explanation of Incorrect Answers:

"Acknowledge the ritualistic behavior each time and point out that it is inappropriate."

Criticizing or labeling the behavior as inappropriate may increase the patient's anxiety and make the compulsions worse. Instead, the nurse should acknowledge the distress behind the behavior and encourage gradual change.

"Allow the patient to carry out the ritualistic behavior, since it is helping them."

While compulsions temporarily reduce anxiety, they reinforce the OCD cycle and do not provide a long-term solution. Allowing rituals without intervention does not teach alternative coping mechanisms.

"Ignore the ritualistic behaviors, and the behaviors will be eliminated due to lack of reinforcement."

OCD compulsions are not maintained by external reinforcement but by internal distress and anxiety. Simply ignoring the behavior does not address the root cause and may make the patient feel unheard.

Summary:

The most appropriate intervention for a patient with OCD is to collaborate with them to gradually reduce compulsive behaviors. This approach respects their anxiety, fosters trust, and encourages effective coping strategies for long-term management.

Correct Answer: C. Administer an IV reversal agent.

Rationale:

The client is exhibiting signs of respiratory depression and sedation following anesthesia. The key concerning findings are:

Respiratory rate of 10 breaths/minute (low) → Sign of respiratory depression

Oxygen saturation of 90% (low) → Indicates hypoxia

Drowsiness and hypotension (90/70 mmHg) → Possible anesthetic or opioid overdose

These symptoms suggest sedative or opioid-induced respiratory depression, which requires an IV reversal agent (naloxone for opioids, flumazenil for benzodiazepines). Administering a reversal agent is the priority intervention to restore adequate respiratory function.

Why the Other Options Are Incorrect:

A. Place in Trendelenburg position.

The Trendelenburg position (head lower than feet) is not appropriate because this does not address respiratory depression and could worsen oxygenation. This position is mainly used for hypotension or shock, but here, the primary concern is respiratory suppression.

B. Give a PRN antiemetic.

Nausea is a common postoperative symptom, but it is not the priority when the client is experiencing respiratory depression. Addressing oxygenation and breathing takes precedence over treating nausea.

D. Apply oxygen at 2 liters/min via nasal cannula.

Oxygen may help temporarily, but it does not correct the underlying cause of respiratory depression. The primary issue is depressed respiratory drive due to anesthesia or opioids, which requires a reversal agent to restore normal breathing.

Summary:

The most important intervention is to reverse the effects of anesthesia or opioids to restore normal respiratory function. Administering an IV reversal agent (Option C) is the priority action because it directly addresses the life-threatening respiratory depression. Oxygen and antiemetics can be used after stabilizing the client’s breathing.

Correct Answer:

d. Echolalia

Explanation:

Echolalia is a common feature of language development in autistic children. It refers to the repetition of words or phrases that the child hears, often without understanding their meaning. It can be:

• Immediate echolalia – The child repeats words or phrases right after hearing them.


• Delayed echolalia – The child repeats words or phrases later, sometimes out of context (e.g., repeating a TV commercial phrase when asked a question).

Echolalia can be a self-soothing mechanism or a way for autistic children to process language before they develop meaningful communication skills. Some children eventually outgrow it, while others continue to use it in specific contexts.

Why the Other Options Are Incorrect:

• a. Scanning speech
  
  
  
  
  • Incorrect because scanning speech refers to an irregular speech pattern where words are spoken slowly, with pauses (often seen in neurological disorders like multiple sclerosis). It is not characteristic of autism.
  
  
  
  


• b. Speech lag
  
  
  
  • Incorrect because while many autistic children do experience delayed speech development, echolalia is a more specific feature of their language pattern. "Speech lag" is a general term and does not accurately describe the repetitive nature of autistic speech.
  
  
  
  


• c. Stuttering
  
  
  
  • Incorrect because stuttering (shuttering is likely a typo) is a speech disorder involving repetitions, prolongations, or blocks in speech. It is not a hallmark feature of autism but rather a distinct speech disorder.
  
  
  
  

Summary:

Autistic children often exhibit echolalia (option d), a speech pattern characterized by the repetition of words or phrases. Other options describe different speech issues that are not specifically linked to autism.

Correct Answer: a. The injury isn't consistent with the history or the child's age

Explanation:

The strongest indicator of child abuse is when the injury does not match the given history or is not appropriate for the child’s age or developmental level. For example, a 2-month-old infant with a spiral fracture (which typically results from twisting force) would be highly suspicious because an infant at this age cannot generate such force independently. Similarly, severe bruises in non-mobile children raise concerns for non-accidental trauma. Healthcare providers must be vigilant in recognizing inconsistencies between the reported mechanism of injury and medical findings, as this is often a red flag for physical abuse.

Why the Other Choices Are Incorrect:

b. The mother and father tell different stories regarding what happened

While inconsistent stories can raise suspicion, they are not definitive proof of abuse. Parents may be confused, anxious, or recalling events differently, especially in a stressful situation.

c. The family is poor

Socioeconomic status is not a direct indicator of abuse. Child maltreatment occurs across all income levels. Assuming abuse based on poverty alone is biased and inaccurate.

d. The parents are argumentative and demanding with emergency department personnel

Aggression or frustration does not automatically indicate abuse. Some parents react strongly out of fear or stress when their child is injured. While hostility may raise concerns, it is not as strong of an indicator as an injury that does not match the history.

Summary:

The most reliable sign of child abuse is when the injury is inconsistent with the child’s age or the history provided (Option A). Healthcare providers must be alert to unexplained injuries, inconsistent explanations, and developmental mismatches, as these are key indicators of potential non-accidental trauma.

Correct Answer: Listen, redirect the patient to their feelings, and explore the issue with the staff.

Explanation 

The nurse’s role is to validate the patient’s feelings, encourage expression, and explore concerns in a therapeutic way. Listening helps the patient feel heard and understood. Redirecting the patient to their feelings allows them to explore the underlying emotions, such as shame, guilt, or fear of rejection. Exploring the issue with the staff ensures that the patient’s concerns are addressed appropriately, promoting a supportive and nonjudgmental environment.

Explanation of Incorrect Answers:

"Apologize for the staff's behavior."

While acknowledging the patient’s feelings is important, apologizing without understanding the situation may not be appropriate. It could imply wrongdoing without confirming whether staff behavior was actually avoidant.

"Explain that feelings of rejection are typical after self-mutilation."

This statement may invalidate the patient’s emotions by generalizing their experience. While feelings of rejection can be common, the focus should be on the patient’s unique experience rather than assuming all patients feel this way.

"Report the matter to the nurse manager."

Escalating the issue immediately without first assessing the situation may not be necessary. If an actual issue with staff behavior is identified, addressing it within the team first may be more effective.

Summary:

The best approach is to actively listen, explore the patient’s feelings, and address concerns with staff. This fosters trust, emotional processing, and a therapeutic environment. Avoid responses that invalidate emotions, assume wrongdoing, or escalate unnecessarily.
