A nurse on an inpatient psychiatric unit is caring for a client with bipolar I disorder who is experiencing an acute manic episode. The client is speaking rapidly, pacing the common area, and intruding on the personal boundaries of other clients. Which action should the nurse take first?

Cevabı ve açıklamayı göster

Cevap: Offer the client a high-calorie finger food and guide them to a quieter, less stimulating area.

Cevap

The nurse should first offer the client a high-calorie finger food and guide them to a quieter, less stimulating area.
Clients experiencing an acute manic episode suffer from an excess of energy, extreme distractibility, and poor impulse control. The most appropriate first action is to reduce environmental stimuli by guiding the client to a quieter area, which helps prevent escalation and protects the milieu. Additionally, clients in a manic state often pace endlessly and fail to sit down to eat, putting them at severe risk for exhaustion and extreme weight loss. Providing high-calorie, high-protein finger foods allows the client to eat while moving, safely meeting their nutritional and metabolic needs.

Adım Adım Çözüm

1
Analyze the client's current clinical presentation.
The client is exhibiting signs of acute mania, including hyperactivity, poor impulse control, and boundary intrusions in a highly stimulating environment.
Identifying the phase of bipolar disorder determines the physiological and psychological priorities of care.
2
Evaluate the safety of the current milieu.
The client's behavior in the common area risks escalating conflict with other clients due to boundary violations and high sensory input.
A highly stimulating environment exacerbates manic behavior and increases the risk of a crisis.
3
Select the most appropriate initial intervention based on safety and prioritization principles.
The nurse selects an intervention that reduces environmental stimulation (moving to a quiet area) and addresses the high metabolic demands of pacing (providing finger foods), adhering to the principle of least restrictive care.
Less restrictive interventions and physiological safety must take priority over chemical restraints or inappropriate communication.

A client with symptomatic anemia is scheduled to receive a transfusion of packed red blood cells (PRBCs). The nurse is gathering supplies to prime the Y-type blood administration set. Which intravenous fluid must the nurse select to hang with the blood product?

Cevabı ve açıklamayı göster

Cevap: 0.9% sodium chloride

Cevap

The only safe and compatible fluid to use with a blood transfusion is 0.9% sodium chloride (normal saline).
Only 0.9% sodium chloride (normal saline) is isotonic and entirely compatible with blood products. It maintains the integrity of the red blood cells, preventing hemolysis (rupture) and ensuring no clots form within the administration set.

Adım Adım Çözüm

1
Identify the prescribed therapy and required equipment.
The client is receiving PRBCs, which require a Y-type administration set primed with a compatible fluid.
Safe administration of blood products requires specific protocols to prevent potentially fatal complications.
2
Evaluate the compatibility of standard intravenous fluids with blood products.
Fluids containing calcium cause clotting, while hypotonic or dextrose-containing fluids cause red blood cell hemolysis.
Mixing incompatible fluids with blood destroys the red blood cells before they enter the client's circulation.
3
Select the correct fluid.
0.9% sodium chloride is identified as the correct fluid.
It is isotonic and does not interact with the cellular components or preservatives in the blood product.

The healthcare provider prescribes knee-length anti-embolic stockings for a newly admitted client who is on bed rest. To promote proper venous return and prevent tissue injury, in what order should the nurse perform the steps to apply the stockings? Arrange the actions in the correct chronological sequence.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence for applying anti-embolic stockings is to position the client supine, invert the stocking to the heel, slide it over the toes and heel, pull it up the calf, and finally smooth out any wrinkles.
Correct application of anti-embolic stockings requires preparation of both the client and the garment. The client must be supine to minimize edema. Preparing the stocking by inverting it to the heel pocket ensures a smooth application over the foot. Anchoring the foot first allows the nurse to pull the rest of the stocking up without twisting. Finally, ensuring the stocking is smooth prevents localized pressure points that could impede circulation.

Adım Adım Çözüm

1
Position the client supine in bed for 15 to 30 minutes.
Dependent fluid drains from the legs.
This prevents trapping venous blood and edema inside the stocking before compression is applied.
2
Invert the stocking by grasping the heel pocket.
The stocking is prepared for smooth application.
This technique allows the stocking to slide over the foot easily without bunching.
3
Slide the foot portion over the toes and heel.
The foot of the stocking is anchored correctly.
Proper alignment over the heel is crucial for the stocking's graduated compression design.
4
Pull the main body of the stocking over the calf.
The stocking covers the lower leg.
This provides the intended therapeutic compression to the superficial and deep veins.
5
Smooth out any wrinkles and check the top edge.
The stocking lies perfectly flat against the skin.
Wrinkles or rolled edges create areas of excessive pressure that can restrict blood flow like a tourniquet.

Cevap

The correct sequence is to first decline the family member's offer, then obtain a certified medical interpreter, brief the interpreter before the session, arrange the room for face-to-face interaction, and finally conduct the interview by speaking directly to the client.
Providing culturally competent care when a language barrier exists requires a systematic approach. The nurse must first ensure safety and confidentiality by declining the use of family members (such as the adult son) as interpreters, especially for legally binding processes like informed consent. Next, the nurse secures a facility-approved certified medical interpreter. Before the interview begins, the nurse must brief the interpreter on the clinical goals to ensure accurate translation of complex medical concepts. The nurse then arranges the room to face the client directly, which establishes a therapeutic connection. Finally, during the interview, the nurse speaks directly to the client, not the interpreter, using short sentences to facilitate accurate translation and demonstrate respect for the client.

Adım Adım Çözüm

1
Address the immediate risk of using an unqualified interpreter.
The nurse informs the son that policy requires a certified medical interpreter.
Using family members, especially for informed consent, compromises confidentiality, risks inaccurate medical translation, and may alter family dynamics.
2
Secure appropriate language services.
The nurse obtains a certified medical interpreter.
Professional medical interpreters are trained in medical terminology, ethics, and cultural brokering, ensuring safe and accurate communication.
3
Prepare the interpreter for the encounter.
The nurse conducts a brief pre-interview conference with the interpreter.
Briefing the interpreter on the clinical context and goals ensures they are prepared for the specific medical procedures and any sensitive topics that will be discussed.
4
Establish a therapeutic physical setup.
The nurse arranges the environment so they are face-to-face with the client.
Positioning the nurse and client face-to-face maintains the nurse-client relationship and allows the nurse to observe the client's nonverbal communication.
5
Conduct the culturally competent interview.
The nurse speaks directly to the client using short sentences and frequent pauses.
Directing conversation to the client, rather than the interpreter, demonstrates respect and acknowledges the client's autonomy.

Cevabı ve açıklamayı göster

Cevap

The correct sequence prioritizes safety and trauma-informed care: maintain distance/avoid touch, clear the milieu, verbally reorient, utilize grounding techniques, and remain with the client.
The sequence for managing an acute dissociative flashback follows the principles of trauma-informed care and milieu safety. First, the nurse must ensure personal safety by maintaining distance and avoiding touch, as touch can trigger a combative response. Second, the nurse secures the milieu by clearing bystanders, which also reduces environmental stimuli. Third, verbal reorientation is initiated using a calm voice and the client's name. Fourth, once the client can hear the nurse, active grounding techniques are used to solidify reality testing. Finally, the nurse remains with the client to provide ongoing support until the episode concludes.

Adım Adım Çözüm

1
Maintain a safe physical distance and strictly refrain from touching the client.
Prevents the nurse from being injured and prevents the client from misinterpreting touch as an assault.
During a PTSD flashback, the client is reliving a traumatic event. Sudden touch triggers defensive, fight-or-flight responses.
2
Instruct other individuals to clear the immediate area to reduce noise and stimuli.
Secures the environment, protects bystanders, and reduces sensory overload.
A quiet environment is necessary before verbal reorientation can be effective, and bystander safety is a priority in the psychiatric milieu.
3
Address the client by name and provide verbal reassurance that they are safe in the hospital.
Initiates reality testing by providing clear, factual information about the present moment.
The client's mind is currently in the past; objective verbal orientation helps pull their consciousness back to the present without overwhelming them.
4
Encourage the client to focus on their current surroundings by describing what they see.
Actively anchors the client in the 'here and now'.
Sensory grounding techniques (like the 5-4-3-2-1 method) force the brain to process current sensory input, which interrupts the dissociative trauma loop.
5
Stay continuously with the client until the dissociative episode completely subsides.
Provides psychological safety and ensures clinical stability before the nurse leaves.
Clients often feel severe anxiety, confusion, or shame following a flashback; continuous presence facilitates full recovery to baseline.

While conducting morning assessments, it is noted that a client's central venous catheter tubing has accidentally disconnected from the injection cap. The client abruptly gasps, exhibits severe dyspnea, and reports a sensation of impending doom. Suspecting an air embolism, arrange the following nursing interventions in the correct sequence to minimize physiological complications.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first clamp the catheter, then place the client in a left lateral Trendelenburg position, administer 100% oxygen, notify the rapid response team, and finally obtain a complete set of vital signs.
When an air embolism is suspected due to a disconnected central venous line, the absolute priority is to stop more air from entering by clamping the line. The next critical action is client positioning (left lateral Trendelenburg) to trap the air in the right ventricle, preventing it from reaching the lungs. Once the mechanical threat is stabilized, addressing hypoxia with 100% oxygen is necessary. Only after these immediate life-saving steps are taken should the nurse summon the rapid response team, followed by assessing vital signs to provide continuous data to the arriving team.

Adım Adım Çözüm

1
Clamp the open central venous catheter.
Halts the entry of ambient air into the bloodstream.
Source control is always the initial step in mitigating an active procedural complication to prevent worsening of the condition.
2
Turn the client onto their left side with the head lower than the feet (Trendelenburg).
Traps the air bubble in the right side of the heart.
This specific position prevents the embolus from migrating into the pulmonary circulation, where it would cause a massive and potentially fatal pulmonary embolism.
3
Apply high-flow oxygen.
Increases alveolar oxygen tension.
Addresses the severe hypoxia and promotes the diffusion and resorption of the nitrogen-rich air bubble.
4
Call the rapid response team.
Mobilizes advanced medical support to the bedside.
The client requires urgent medical evaluation and potential advanced interventions after initial physical safeguards are placed.
5
Measure vital signs.
Establishes a baseline post-event hemodynamic profile.
Provides critical assessment data to the response team immediately upon their arrival without delaying life-saving actions.

A nurse on a medical-surgical unit is assessing a client who has a history of heavy alcohol consumption. The client's last drink was approximately 48 hours ago. Which of the following clinical findings should the nurse recognize as manifestations of alcohol withdrawal? Select all that apply.

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Restlessness and agitation; Diaphoresis; Elevated blood pressure

Cevap

The correct manifestations of alcohol withdrawal are restlessness and agitation, diaphoresis, and elevated blood pressure.
Because alcohol is a central nervous system depressant, abrupt cessation leads to a rebound effect known as autonomic hyperactivity. This overactivity results in expected withdrawal symptoms such as restlessness, agitation, diaphoresis (excessive sweating), and elevated blood pressure.

Adım Adım Çözüm

1
Analyze the client's clinical history and timeline.
The client has a history of heavy alcohol use and stopped drinking 48 hours ago.
Establishing the timeline helps identify that the client is within the peak window for acute alcohol withdrawal syndrome.
2
Recall the physiological effects of alcohol withdrawal.
Alcohol withdrawal leads to a rebound effect characterized by autonomic hyperactivity and central nervous system excitability.
Understanding that withdrawal causes hyperactive responses provides the basis for anticipating specific symptoms.
3
Evaluate each option against the expected signs of autonomic hyperactivity.
Restlessness, diaphoresis, and elevated blood pressure align with this hyperactive profile. Bradycardia and increased appetite do not.
Systematically verifying each option ensures that only the true manifestations of withdrawal are selected.

A nurse is caring for a client admitted with a severe acute asthma exacerbation. The client has been receiving continuous albuterol nebulization and intravenous corticosteroids. During reassessment, the nurse observes that the client is becoming increasingly lethargic and the respiratory rate has decreased from 34 to 12 breaths per minute. Auscultation reveals a 'silent chest' with no audible wheezing. The latest arterial blood gas (ABG) results on room air are: pH 7.28, PaCO2 62 mm Hg, PaO2 55 mm Hg, and HCO3 26 mEq/L. Which action is the priority for the nurse to reduce the risk of a fatal outcome?

Cevabı ve açıklamayı göster

Cevap: Activate the rapid response team and prepare the client for immediate endotracheal intubation.

Cevap

The priority action is to activate the rapid response team and prepare the client for immediate endotracheal intubation.
The correct answer addresses the immediate need for airway management. The client is exhibiting classic signs of impending respiratory failure: decreasing level of consciousness (lethargy), a paradoxical drop in respiratory rate due to muscle fatigue, and a 'silent chest'. A silent chest indicates severe airflow obstruction where there is not enough air movement to produce a wheeze. The ABG results confirm acute uncompensated respiratory acidosis with severe hypoxemia. The absolute priority is securing the airway and initiating mechanical ventilation to prevent cardiac and respiratory arrest.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client is lethargic, has a decreasing respiratory rate, and a 'silent chest'.
These are critical signs of muscle fatigue, impending respiratory arrest, and severe airflow obstruction, not signs of clinical improvement.
2
Interpret the arterial blood gas (ABG) results.
The ABG shows uncompensated respiratory acidosis (pH 7.28, PaCO2 62) and significant hypoxemia (PaO2 55).
This confirms acute respiratory failure and the client's inability to maintain adequate spontaneous ventilation.
3
Determine the highest priority intervention to reduce physiological risk.
The client requires immediate mechanical ventilatory support.
Airway and breathing are the immediate life-saving priorities according to the ABC (Airway, Breathing, Circulation) framework.

Cevabı ve açıklamayı göster

Cevap: Maintain the head of the bed at an elevation of 30∘30^\circ to 45∘45^\circ continuously while the enteral nutrition is infusing.; Assist the client into an orthopneic position, sitting up and leaning forward over an overbed table, during episodes of severe dyspnea.

Cevap

The correct interventions are maintaining the head of the bed elevated between 30∘30^\circ and 45∘45^\circ during continuous enteral feedings, and assisting the client into an orthopneic position during acute dyspneic episodes.
Maintaining the head of the bed elevated between 30∘30^\circ and 45∘45^\circ uses gravity to prevent esophageal reflux and subsequent pulmonary aspiration of the continuous enteral feeding. Assisting the client into an orthopneic position (sitting up and leaning forward over an overbed table) optimizes diaphragmatic excursion, recruits accessory respiratory muscles, and significantly decreases the work of breathing during severe dyspneic episodes.

Adım Adım Çözüm

1
Analyze the client's primary diagnoses and compounding physiological risks.
The client presents with a severe COPD exacerbation (high risk for hypoxia and respiratory failure) and is receiving nutrition via a newly placed PEG tube (high risk for pulmonary aspiration).
Identifying overlapping physiological risks is essential for prioritizing safe and effective basic care interventions.
2
Evaluate the safety and therapeutic appropriateness of the proposed positioning interventions.
Elevating the head of the bed to 30∘30^\circ-45∘45^\circ safely mitigates aspiration risk. The orthopneic position safely maximizes lung expansion. A flat supine position is strictly contraindicated as it worsens both COPD respiratory distress and PEG aspiration risk.
Correct client positioning is a fundamental basic care intervention that directly impacts both respiratory efficiency and gastrointestinal safety.
3
Assess the administrative, delegation, and educational interventions for clinical and regulatory compliance.
Delegating initial PEG feedings and obtaining PRN restraint prescriptions are fundamentally unsafe and violate legal practice standards. Furthermore, dismissing acute sudden-onset confusion as normal aging ignores a critical warning sign of systemic hypoxia.
Safe nursing care plans must strictly adhere to legal delegation boundaries, rigorous restraint protocols, and accurate pathological assessment.

During a routine follow-up appointment at an outpatient clinic, a client with early-stage dementia is accompanied by a family caregiver. While the nurse is preparing to obtain vital signs, the caregiver suddenly grasps the client's forearm tightly and speaks in a harsh, threatening tone. The nurse observes several distinct, fading bruise marks resembling fingertips on the client's bilateral upper arms. What is the priority nursing action?

Cevabı ve açıklamayı göster

Cevap: Intervene calmly to separate the client and caregiver by stating that a private physical examination is a standard clinic requirement.

Cevap

The priority action is to separate the client from the caregiver using a non-confrontational rationale, such as stating that a private examination is a standard clinic policy.
The correct answer addresses the most critical and immediate need: client safety. By using a standard clinic policy as the reason for separation, the nurse de-escalates the situation, avoids putting the caregiver on the defensive, and creates a safe environment to interview the vulnerable client privately. Once the client is safe, the nurse can proceed with a thorough assessment, precise documentation using direct quotes, and mandatory reporting.

Adım Adım Çözüm

1
Assess the immediate environment for safety and identify the primary risk.
The client is in immediate proximity to an aggressive caregiver, and there are physical signs (fingerprint bruises) suggesting ongoing abuse.
According to Maslow's Hierarchy of Needs, physiological safety is the highest priority in an acute situation.
2
Determine the most therapeutic and safe intervention to protect the client.
A non-confrontational separation strategy prevents escalation while allowing the nurse to interview the client privately.
Direct confrontation can trigger increased violence and cause the caregiver to remove the client from the healthcare setting, blocking further assistance.
3
Plan subsequent mandatory actions after immediate safety is secured.
Once separated, the nurse will conduct a full assessment, document findings objectively (using direct quotes), and fulfill the legal obligation of mandated reporting.
Mandatory reporting is triggered by reasonable suspicion, but securing the client's physical safety must occur first.

Which of the following is the most therapeutic nursing response?

Cevabı ve açıklamayı göster

Cevap: Art seems to be a major part of your life. How are you feeling about everything that has happened today?

Cevap

The most therapeutic response is to acknowledge the importance of art to the client and use open-ended communication to explore their current feelings, allowing them to process the trauma at their own pace.
The client is using denial, an initial coping mechanism that acts as a psychological shock absorber against the overwhelming reality of the traumatic amputation. The correct response acknowledges what is important to the client and uses an open-ended question to gently focus on their emotions. This therapeutic approach does not validate the unrealistic plan, nor does it harshly confront the denial, allowing the client a safe space to process the profound loss at a tolerable pace.

Adım Adım Çözüm

1
Identify the client's current behavioral cues and coping mechanism.
The client is exhibiting denial regarding the traumatic loss of their hand, acting as if the life-altering surgery did not occur.
Denial is a common, initial protective defense mechanism against sudden, overwhelming emotional trauma and loss.
2
Evaluate the nursing communication options against psychiatric nursing principles for handling denial.
Confronting the denial, asking 'why', and giving false reassurance are identified as non-therapeutic communication techniques.
These approaches block communication, provoke defensiveness, or strip the client of a necessary psychological defense before they are ready to cope with reality.
3
Select the response that fosters a therapeutic alliance.
Acknowledging the client's interest in art and asking an open-ended question about their feelings is the priority action.
This gently focuses on the client's emotional state without validating the unrealistic plan or harshly shattering the protective denial.

Cevap

The correct sequence is: establishing a safe physical presence, acknowledging the distress, setting behavioral limits, offering concrete choices, and finally using therapeutic silence.
In a crisis scenario, therapeutic communication must follow a structured sequence to de-escalate the situation safely. The nurse must first ensure safety by maintaining distance and using non-threatening body language (non-verbal communication). Next, the nurse establishes verbal contact by acknowledging the client's distress, which validates their feelings and begins to build trust. Once contact is made, the nurse sets clear, simple limits on the disruptive behavior, as agitated clients require concrete boundaries. Immediately after setting limits, the nurse should offer acceptable choices to restore the client's sense of control and avoid a power struggle. Finally, the nurse must employ therapeutic silence, giving the client adequate time to process the options, as high anxiety significantly delays cognitive processing.

Adım Adım Çözüm

Cevabı ve açıklamayı göster

Cevap: 24.9

Cevap

24.9
To safely perform an upward titration of a continuous weight-based vasoactive infusion, the nurse must accurately calculate the incremental volume increase and add it to the current baseline rate. First, find the concentration: \(500\text{ mg} = 500,000\text{ mcg}\); \(500,000\text{ mcg} \div 250\text{ mL} = 2,000\text{ mcg/mL}\). Next, calculate the increase needed: \(2.5\text{ mcg/kg/min} \times 92\text{ kg} = 230\text{ mcg/min}\). Convert this to an hourly dose: \(230\text{ mcg/min} \times 60\text{ min/hr} = 13,800\text{ mcg/hr}\). Determine the pump volume for this increase: \(13,800\text{ mcg/hr} \div 2,000\text{ mcg/mL} = 6.9\text{ mL/hr}\). Finally, add this volume to the current rate: \(18\text{ mL/hr} + 6.9\text{ mL/hr} = 24.9\text{ mL/hr}\).

Adım Adım Çözüm

1
Calculate the concentration of the dobutamine infusion in mcg/mL.
\(2,000\text{ mcg/mL}\)
Converting to mcg/mL establishes the baseline concentration needed to calculate volume for the weight-based dose, since dobutamine is dosed in mcg/kg/min.
2
Determine the required dose increase per minute based on the client's weight.
\(230\text{ mcg/min}\)
The protocol requires an increase of 2.5 mcg/kg/min. Multiplying by the client's weight (92 kg) gives the total mcg per minute to add.
3
Convert the dose increase from a per-minute rate to a per-hour rate.
\(13,800\text{ mcg/hr}\)
IV pumps are programmed in mL/hr, so the medication dose must be converted to an hourly rate before calculating the corresponding fluid volume.
4
Calculate the additional volume rate (mL/hr) required to deliver the dose increase.
\(6.9\text{ mL/hr}\)
Dividing the hourly dose (13,800 mcg/hr) by the concentration (2,000 mcg/mL) determines how much additional fluid volume is needed per hour.
5
Add the calculated additional volume rate to the current infusion pump rate.
\(24.9\text{ mL/hr}\)
The question asks for the NEW rate on the IV pump, which is the sum of the current continuous rate (18 mL/hr) and the calculated titration increase (6.9 mL/hr).

A client is brought to a mental health triage center by a family member after experiencing a sudden, catastrophic financial loss. The client is pacing the waiting room rapidly, hyperventilating, wringing their hands, and shouting, "I can't even think! Everything is ruined! My life is completely over!" Which of the following is the priority nursing intervention?

Cevabı ve açıklamayı göster

Cevap: Use a calm, firm voice and direct the client to sit and take slow, deep breaths.

Cevap

The priority intervention is to use a calm, firm voice and direct the client to sit and take slow, deep breaths.
The correct intervention prioritizes the client's immediate physiological and safety needs. Hyperventilation and disorganized behavior indicate severe anxiety or panic. At this level of anxiety, the client's perceptual field is severely narrowed, and they cannot process complex information. The nurse must first lower the anxiety level through direct, simple instructions and physiological stabilization (guided breathing) before any other assessment or therapeutic work can occur.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client is hyperventilating, pacing rapidly, and stating they "can't even think," which are definitive signs of the severe to panic level of anxiety.
Identifying the current anxiety level determines the client's cognitive capacity and immediate needs.
2
Apply prioritization frameworks (Maslow's Hierarchy and ABCs).
Physiological stabilization (addressing hyperventilation and restoring normal breathing) takes precedence over psychological assessment (suicide risk) or problem-solving.
According to Maslow, physiological needs must be met before safety needs. A client cannot accurately respond to a safety assessment while actively hyperventilating and unable to think clearly.
3
Select the appropriate communication strategy for severe anxiety.
Providing direct, simple, and authoritative instructions (e.g., "sit down," "breathe slowly") is the most effective approach.
In severe anxiety, the perceptual field is drastically narrowed. The client cannot process open-ended questions or complex reasoning.

An individual arrives at the community health clinic seeking help for alcohol dependence. To establish a safe monitoring timeline and anticipate physiological risks, which assessment question is the highest priority for the clinic nurse to ask first?

Cevabı ve açıklamayı göster

Cevap: "When did you take your last drink of alcohol?"

Cevap

The most important question is asking when the client took their last drink of alcohol.
The correct response directly targets the timeline of alcohol withdrawal. Because life-threatening withdrawal symptoms (such as seizures and delirium tremens) occur at predictable intervals after the cessation of drinking, establishing the exact time of the last drink is the most critical piece of data for anticipating and managing the client's physiological safety.

Adım Adım Çözüm

1
Analyze the client's presentation and the goal of the assessment.
The client has alcohol dependence, and the nurse must anticipate physiological risks (withdrawal).
Identifying the primary clinical goal dictates the prioritization of assessment questions.
2
Apply the principles of alcohol withdrawal pathophysiology.
Alcohol withdrawal symptoms predictably begin within a specific timeframe (usually 6-8 hours) after the last drink.
Understanding the timeline of withdrawal is required to keep the client physiologically safe.
3
Evaluate each option based on physiological safety (Maslow's Hierarchy).
Determining the exact time of the last drink is the only question that provides data to predict and manage acute physiological deterioration.
Physiological safety and airway/breathing/circulation (ABCs) always take priority over psychosocial assessments or readiness to change.

A nurse is caring for a client with enterococcal endocarditis who is receiving a continuous intravenous (IV) infusion of ampicillin. The healthcare provider prescribes a scheduled dose of IV gentamicin to be infused over 60 minutes. The client has a single-lumen peripherally inserted central catheter (PICC). Knowing that ampicillin and gentamicin are chemically incompatible, which action should the nurse take to safely administer the scheduled dose?

Cevabı ve açıklamayı göster

Cevap: Stop the ampicillin infusion, flush the PICC lumen with 10 mL of 0.9% sodium chloride, infuse the gentamicin, and flush the line again before restarting the ampicillin.

Cevap

The correct action is to stop the continuous ampicillin infusion, flush the line thoroughly with normal saline, administer the gentamicin over the prescribed 60 minutes, and flush the line again before restarting the ampicillin.
When administering an intermittent IV medication that is physically or chemically incompatible with a continuous infusion through a single-lumen catheter, the nurse must utilize sequential administration. This involves stopping the continuous infusion, flushing the line with a compatible fluid (such as 0.9% sodium chloride) to clear the catheter, administering the intermittent medication, and thoroughly flushing the line again before restarting the continuous infusion. This protocol ensures the two medications never physically interact.

Adım Adım Çözüm

1
Identify the chemical incompatibility between the continuous ampicillin (a penicillin) and the scheduled gentamicin (an aminoglycoside).
Recognition that these medications cannot be administered concurrently or allowed to mix in the same intravenous line.
Penicillins chemically inactivate aminoglycosides and can form precipitates if they come into contact.
2
Determine the safest administration method given the constraint of a single-lumen PICC line.
Selection of sequential administration utilizing a rigorous flushing protocol.
Flushing with a compatible fluid (0.9% sodium chloride) clears the catheter space of the first medication, allowing safe transit of the second medication without physical contact.

Anahtar Kavram

Safe sequential administration of incompatible intravenous medications requires thoroughly flushing the vascular access device with a compatible solution before and after the intermittent dose.

A nurse at an outpatient clinic is interacting with a client who is awaiting the results of a biopsy for a suspicious breast mass. The client is pacing the room and states, "If this is cancer, I do not know how I will tell my children. They are still in school, and they need their mother." Which of the following is the most therapeutic response by the nurse?

Cevabı ve açıklamayı göster

Cevap: You are terrified about receiving a cancer diagnosis and how it might impact your children.

Cevap

The statement that reflects the client's fear about the diagnosis and its impact on the children is the most therapeutic response.
The correct response utilizes the therapeutic communication technique of reflection. By identifying and mirroring the client's underlying feelings of fear regarding their children, the nurse validates the client's emotional state and encourages further open expression of feelings without judgment.

Adım Adım Çözüm

1
Analyze the client's statement to identify the core emotion and concern.
The client is expressing severe anxiety and anticipatory fear regarding a potential cancer diagnosis and the effect it would have on their young children.
Identifying the underlying emotion is the first step in formulating a therapeutic response.
2
Evaluate each option against therapeutic communication principles.
The correct response must validate the client's feelings without judging, minimizing, or interrogating.
Therapeutic communication aims to build trust, validate feelings, and encourage the client to express themselves freely.
3
Select the option that uses reflection or empathy to address the client's stated fears.
The statement reflecting the terror of the diagnosis and its impact on the children directly validates the client's emotional state.
Reflection demonstrates active listening and allows the client to feel heard and understood.

A nurse is caring for an intubated client with acute respiratory distress syndrome (ARDS) who has just been placed in the prone position. The client is receiving continuous enteral nutrition via a nasogastric tube. Which basic care and comfort intervention is the priority for the nurse to implement?

Cevabı ve açıklamayı göster

Cevap: Adjust the entire bed frame into a reverse Trendelenburg tilt to maintain head elevation.

Cevap

Adjust the entire bed frame into a reverse Trendelenburg tilt to maintain head elevation.
When a client is positioned prone, standard elevation of the head of the bed is not physically possible without compromising spinal alignment and respiratory mechanics. Because the client is receiving continuous enteral nutrition, maintaining head elevation relative to the stomach is critical to utilize gravity, prevent gastric reflux, and eliminate the risk of pulmonary aspiration. The reverse Trendelenburg position tilts the entire bed frame, safely achieving this necessary elevation.

Adım Adım Çözüm

1
Identify the client's current clinical state and positioning constraints.
The client is intubated, receiving continuous enteral nutrition, and positioned prone (on their abdomen).
Establishing the specific physiological parameters is essential to identifying safety risks related to basic care.
2
Analyze the risks associated with the concurrent therapies.
Enteral feeding carries a high risk of aspiration if the head is not elevated, but the prone position prevents standard articulation of the head of the mattress.
Aspiration of gastric contents can be rapidly fatal, especially in a client already suffering from ARDS.
3
Determine the appropriate biomechanical intervention that satisfies all requirements.
Tilting the entire bed frame (reverse Trendelenburg) elevates the head and thorax relative to the stomach without bending the client's spine.
This utilizes gravity to promote gastric emptying and prevent reflux while allowing the life-saving prone therapy to continue.
4
Evaluate the remaining options for safety and scope of practice.
Stopping nutrition causes harm, assessing posterior pressure points is irrelevant for a prone client, and delegating airway management to a UAP is unsafe practice.
Ensuring all aspects of basic care adhere to safety standards and legal delegation rules.
