HESI RN 31I Pharmacology Exam

The correct answer is A: Eliminate use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Explanation:

Lithium carbonate is a mood stabilizer commonly prescribed for bipolar disorder to help control the highs (mania) and lows (depression). However, it has a narrow therapeutic range, meaning that its levels in the blood need to be carefully monitored to avoid toxicity.

NSAIDs can interact with lithium and increase lithium levels, which can lead to lithium toxicity. This happens because NSAIDs reduce the renal clearance of lithium, leading to an accumulation of the drug in the body. Symptoms of lithium toxicity include nausea, vomiting, diarrhea, tremors, confusion, and even more severe effects such as seizures or kidney damage.

Therefore, clients taking lithium should be instructed to avoid NSAIDs unless specifically prescribed by a healthcare provider who is aware of the client’s lithium treatment.

Why the other options are incorrect:

B. Notify healthcare provider prior to dental procedures:

While it is generally important to inform healthcare providers about medications before any procedure, this instruction is more specific to medications that can affect bleeding (e.g., anticoagulants) or those that interact with anesthesia. Lithium does not typically require this kind of precaution before dental procedures unless other factors, such as sedation or drug interactions, are involved.

C. Avoid consuming all foods that contain iodine:

This is not necessary for clients taking lithium. While iodine and thyroid function are important to monitor in clients taking lithium (since lithium can affect thyroid function), avoiding iodine-rich foods is not a specific requirement. In fact, iodine is a necessary nutrient, and clients should not unnecessarily restrict it. Instead, monitoring thyroid function through regular blood tests is more important.

D. Monitor blood glucose levels daily:

Lithium does not typically affect blood glucose levels in a direct way. This instruction would be more relevant for clients on medications such as steroids or antipsychotics, which can affect glucose metabolism. Clients taking lithium do not need to monitor blood glucose levels unless they have other conditions (like diabetes) that warrant it.

The correct answer is A: Notify the healthcare provider of the threat.

Explanation of the correct answer:

A. Notify the healthcare provider of the threat

When a client expresses a threat of harm to another person, the nurse’s primary responsibility is to notify the healthcare provider immediately so that further evaluation can be done and appropriate interventions can be implemented. The healthcare provider can assess the client’s risk level, decide on necessary interventions, and determine whether the situation requires further action, such as a psychiatric hold or involvement of law enforcement. This is critical to prevent harm to the potential victim (the sister in this case).

Why the other options are incorrect:

B. Report the threat to the healthcare team

Reporting the threat to the healthcare team is necessary, but it is a broader action. Notifying the healthcare provider directly is a more specific, timely, and targeted intervention that ensures the client is properly evaluated and that necessary steps are taken to ensure the sister’s safety.

C. Document the threat in the medical record

While documenting all significant findings and threats is important, it should not take priority over notifying the healthcare provider. Immediate intervention is required to ensure the safety of the sister and to address the threat appropriately.

D. Inform the sister of the client's threat

While it is important to protect the potential victim, the nurse should not directly inform the sister about the threat without consulting with the healthcare provider. The healthcare provider needs to assess the situation and determine the most appropriate course of action, which may include informing the sister or taking protective actions.

Correct Answer C: Witness to an accident.

Explanation:

Witness to an Accident and Trauma-Related Nightmares:

Nightmares can be a hallmark symptom of post-traumatic stress disorder (PTSD). If the client has witnessed a traumatic event, especially a violent or life-threatening incident, it can trigger recurrent distressing dreams or nightmares related to the trauma. In this case, the client’s history of being a witness to an accident suggests the possibility of a trauma-related nightmare. The brain may repeatedly process the traumatic event during sleep, often leading to intense, vivid nightmares that reflect the stress and emotional impact of what was witnessed.

Why Other Options Are Incorrect:

A: Family history of dementia

While a family history of dementia may raise concerns about cognitive decline and possible sleep disturbances later in life, new-onset violent nightmares are more directly associated with trauma exposure rather than genetic predisposition to dementia. Therefore, trauma history is a more significant factor in this case.

B: Inadequate diversional activity

Lack of diversional activity or stimulation can lead to boredom or restlessness, but it would not directly explain the violent nightmares. Nightmares are typically linked to emotional distress, and diversional activities would have less of an impact on this.

D: Alcohol use

Although alcohol use can contribute to sleep disturbances and may exacerbate nightmares, witnessing an accident is more closely tied to the development of trauma-induced nightmares. If the client’s nightmares began after a traumatic event such as an accident, it is important to explore that event further as it might be the root cause of the current distress.

The correct answer is

A. Intrusive thought

B. Avoidance of places associated with the assault

C. Exaggerated startle response

F. Social withdrawal

Explanation of the correct answers:

A. Intrusive thoughts

Intrusive thoughts are a common symptom of rape-trauma syndrome and other trauma-related disorders. These can include disturbing memories or flashbacks of the assault that resurface unexpectedly, leading to emotional distress and difficulty functioning in daily life.

B. Avoidance of places associated with the assault

Avoidance behaviors are often seen in individuals who have experienced trauma. Survivors may intentionally avoid places, people, or activities that remind them of the assault. This is a way of coping with the emotional pain and anxiety associated with the trauma.

C. Exaggerated startle response

An exaggerated startle response is common in individuals with post-traumatic stress disorder (PTSD), which can be a component of rape-trauma syndrome. Survivors of assault often experience hypervigilance and are easily startled by sudden noises or events, as they remain on high alert for perceived threats.

F. Social withdrawal

Social withdrawal is another common symptom of long-term rape-trauma syndrome. Individuals may avoid social interactions due to feelings of shame, guilt, or fear of being judged. This withdrawal can lead to isolation and difficulty forming or maintaining relationships.

Why the other options are incorrect:

D. Hallucinations

Hallucinations are not typical symptoms of rape-trauma syndrome. While trauma can cause significant emotional distress, hallucinations are more commonly associated with severe mental health conditions, such as schizophrenia or substance abuse, rather than trauma alone.

E. Overeating

Overeating is not a core symptom of rape-trauma syndrome, though some individuals might cope with trauma by engaging in unhealthy eating habits. However, it is not considered a defining characteristic of long-term trauma responses like avoidance, intrusive thoughts, or hyperarousal.

Correct Answer C: Upper abdominal pain.

Explanation:

Potential for Medical Emergency:

Upper abdominal and chest pain following self-induced vomiting raises concern for esophageal rupture (Boerhaave syndrome), gastric or esophageal tears (e.g., Mallory-Weiss tear), or severe gastritis. These are potentially life-threatening complications that require immediate medical assessment and intervention. While the client’s symptoms reflect a broader eating disorder (likely bulimia nervosa), the first priority is always to address acute, potentially emergent medical problems before managing chronic issues or underlying psychiatric illness.

Why Other Options Are Incorrect:

A: Severe heartburn

Although the client reports recent heartburn, this symptom is less urgent than sharp post-vomiting abdominal pain, which could signify a serious internal injury. Heartburn is a common symptom and not as immediately concerning unless it accompanies red flags like hematemesis or dysphagia.

B: Erosion of tooth enamel

Tooth enamel erosion is a chronic complication of purging via vomiting. While this is clinically important and indicates ongoing bulimia, it is not an acute concern and doesn’t require immediate intervention compared to internal pain that may suggest organ injury.

D: Laxative use after binging

Laxative abuse is another sign of disordered eating behavior, but like enamel erosion, this is a longer-term problem. While it can cause serious consequences (e.g., electrolyte imbalances), it is not the most pressing issue compared to acute pain that may reflect gastrointestinal trauma.

Correct Answer A: Performs activities of daily living for 3 sequential days.

Explanation:

Realistic and Measurable for the Client's Condition:

Dementia is a progressive neurocognitive disorder characterized by memory loss, disorientation, impaired judgment, and difficulty performing daily tasks. Because cognitive abilities decline over time, the treatment plan should focus on preserving existing function rather than expecting major cognitive improvement. The goal of performing ADLs (Activities of Daily Living) over three consecutive days provides a measurable, achievable benchmark for short-term progress. It evaluates the client’s functional ability, consistency, and participation in self-care, which are essential for maintaining dignity and slowing functional decline.

Short-Term vs. Long-Term Goal Appropriateness:

Short-term outcomes should be observable within a few days or a week and should be tailored to match the client’s current stage of dementia. Performing ADLs is something that can be realistically monitored by nursing staff and documented as part of a daily routine. If the client is able to complete these tasks consistently, it shows stability in cognitive and physical functioning, which is often a primary goal in the early to moderate stages of dementia.

Why Other Options Are Incorrect:

B: Remembers family members’ names at their next visit

This outcome is too unpredictable and not a dependable measure of progress in dementia. Memory deficits are a core feature of dementia, and name recall is typically impaired as the condition progresses. Even if the client does recognize someone occasionally, it is often inconsistent. This makes it a poorly defined and unrealistic short-term goal, especially in moderate to severe cases.

C: Expresses no paranoid ideation for at least 1 week

Paranoia is a common neuropsychiatric symptom in dementia, but it's not easily resolved in a short time frame. While it can be managed with medication and reassurance, expecting complete absence of paranoid thoughts for a week sets up an unrealistic expectation. It also doesn’t address functionality, which is more critical in early care planning.

D: Verbalizes no hallucinations and delusions for 48 hours

Similar to paranoia, hallucinations and delusions may be intermittent or fluctuate depending on the environment, level of stimulation, and time of day (e.g., sundowning effect). Even with treatment, expecting complete cessation of symptoms within 48 hours is not a realistic short-term goal. Moreover, focusing on verbalization assumes the client has the ability to recognize and articulate those experiences, which may not be possible.

Correct Answer C: The client's serum lithium levels should be routinely evaluated.Explanation

Routine Evaluation of Serum Lithium Levels:

Lithium carbonate has a narrow therapeutic index, meaning the range between therapeutic and toxic levels is very small. Regular monitoring of serum lithium levels is critical to ensure the client remains within a safe and effective range. Toxicity can develop quickly and may present with serious symptoms such as tremors, confusion, gastrointestinal upset, and even seizures or renal failure. Educating the client and family on the importance of consistent lab monitoring helps ensure safety and treatment efficacy, especially when the client transitions to independent living where structure and routine might change.

Why Other Options Are Incorrect:

A: The client should plan to participate in group or individual therapy while at college.

While this is a beneficial recommendation, it is not the most critical piece of information. Therapy is part of comprehensive management, but lithium monitoring is directly linked to the client's physical safety and medication management.

B: The client should be aware of the signs and symptoms of the illness.

Awareness is essential for self-management, but again, this is not the most important aspect in the context of lithium therapy. Missing signs of toxicity is more dangerous than missing signs of mood changes because lithium toxicity can progress rapidly.

D: Despite the illness, the client should be able to live away from home.

This statement may offer emotional reassurance, but it is vague and doesn't provide any actionable or safety-related guidance. It does not address the critical need for lithium monitoring, which is the key focus for someone newly diagnosed and planning a life transition.

The correct answers are 

A. Explore the choices that are currently available to the client, 

B. Restate the client's statements to verify her feelings.

C Reassure the client that she is doing her best in a difficult situation.

Explanation:

A. Explore the choices that are currently available to the client.

This option is correct because exploring available choices empowers the client to make informed decisions about her situation. When experiencing intimate partner violence (IPV), it is important for the client to understand her options for action. This approach fosters autonomy and encourages the client to think through potential actions she could take to improve her safety and well-being.

B. Restate the client's statements to verify her feelings.

This is also correct because restating or paraphrasing the client’s statements ensures that the nurse has understood the client’s feelings. It shows the client that her thoughts and emotions are being heard and validated. This technique can help the client feel more comfortable sharing, and it encourages self-expression in a safe and supportive environment.

C. Reassure the client that she is doing her best in a difficult situation.

Reassurance in this context can be helpful as long as it is genuine and nonjudgmental. It can help the client feel validated and reduce feelings of guilt or inadequacy, which are common in those experiencing IPV. This statement shows empathy for the client’s struggle and can help her feel that she is not alone. However, it is important that the reassurance does not invalidate the seriousness of the situation or the need for action.

Why the other options are incorrect:

D. Confront irrational beliefs to help the client visualize solutions.

This option is less appropriate because directly confronting irrational beliefs may feel overwhelming to a client who is already experiencing emotional turmoil due to IPV. Confrontation may lead to defensiveness or avoidance. Instead, providing a supportive, nonjudgmental environment helps the client feel safe enough to open up.

E. Avoid direct eye contact when communicating with the client.

Avoiding eye contact could inadvertently signal a lack of interest or understanding. In most cases, gentle eye contact fosters connection and empathy, and helps the client feel heard and supported. However, cultural considerations should always be taken into account when deciding on appropriate communication styles.

The correct answer is B: Rapid weight gain.

Explanation of the correct answer:

B. Rapid weight gain.

Sertraline is a selective serotonin reuptake inhibitor (SSRI) used to treat depression. One of the potential side effects of SSRIs is weight gain, and rapid weight gain can sometimes signal serious side effects such as serotonin syndrome or a more severe adverse reaction to the medication. It could also be a sign of fluid retention, which may indicate heart failure or other underlying issues that need immediate medical attention. Therefore, rapid weight gain should be reported to the healthcare provider as it may signal an adverse or serious condition.

Why the other options are incorrect:

A. Gastric irritation.

Gastric irritation, including symptoms like nausea or mild stomach upset, is a common and mild side effect of SSRIs like sertraline, especially during the early stages of treatment. While it can be uncomfortable, it is generally not considered a serious adverse effect that requires immediate reporting unless it persists or worsens.

C. Dry mucosal membranes.

Dry mouth or dry mucosal membranes are also a common side effect of SSRIs and are typically mild and temporary. While uncomfortable, it is not usually a sign of a serious condition and does not need to be urgently reported unless it leads to severe discomfort or difficulty swallowing, which could indicate dehydration or other issues that need attention.

D. Photosensitivity.

Photosensitivity, or increased sensitivity to sunlight, is a possible side effect of some medications, including certain SSRIs. However, it is typically not a common or serious reaction to sertraline and does not usually require immediate reporting unless it leads to severe sunburns or other significant reactions.
