Question 1701Question →

A nurse is preparing to administer a scheduled dose of intravenous pantoprazole to a client. The client is currently receiving a continuous infusion of total parenteral nutrition (TPN) through a single-lumen peripherally inserted central catheter (PICC). Which of the following is the most appropriate action by the nurse?

Show answer & explanation

Answer: Establish a new peripheral intravenous catheter to administer the medication.

Answer

Establish a new peripheral intravenous catheter to administer the medication.
Total Parenteral Nutrition (TPN) solutions have high glucose and amino acid concentrations, making them highly prone to bacterial growth and chemical incompatibilities. Evidence-based nursing practice dictates that TPN must be administered through a dedicated central line lumen. No other medications, intravenous fluids, or blood products should be administered through this specific lumen. Because the client currently has only a single-lumen PICC which is actively in use for the TPN, the nurse must establish a new peripheral intravenous site to administer the scheduled pantoprazole safely.

Step-by-Step Solution

1
Identify the client's current intravenous access and ongoing infusions.
The client has a single-lumen PICC that is actively being used for a continuous TPN infusion.
Evaluating current vascular access is required before safely administering any new intravenous medication.
2
Recall the safety administration principles for Total Parenteral Nutrition.
TPN solutions require a dedicated central venous line or lumen; no other fluids or medications can share this access.
TPN has a high osmolarity, high glucose content, and specific pH that increases the risk of infection, chemical incompatibility, and precipitate formation when mixed with other drugs.
3
Determine the safest method to administer the prescribed pantoprazole.
Since the sole central line lumen is dedicated to TPN, a new peripheral IV catheter must be inserted.
Providing alternative venous access ensures the client receives the scheduled medication without compromising the safety of the TPN infusion.

Question 1702Question →

While working on an acute mental health unit, the nurse observes a client clenching their fists, breathing rapidly, and swearing loudly at others in the dayroom. The client shouts, 'I'm going to hurt someone if I don't get out of here!' Arrange the following nursing actions in the proper sequence from the least restrictive to the most restrictive intervention.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: engage the client verbally, direct them to a quiet environment, offer voluntary oral medication, administer an involuntary IM medication, and finally apply mechanical restraints.
The doctrine of the least restrictive environment dictates that psychiatric clients have the right to be treated using the minimum level of restriction necessary to maintain the safety of the client and others. The hierarchy begins with verbal techniques (the least restrictive), followed by behavioral and environmental modifications such as moving to a quiet space. If these fail, voluntary pharmacological interventions (oral PRN medications) are offered. If the client refuses and continues to pose an imminent threat, involuntary chemical restraints (IM medications) are administered. Mechanical physical restraints are the absolute most restrictive measure and are strictly reserved as a last resort.

Step-by-Step Solution

1
Analyze the client's behavior and the immediate safety risks.
The client is highly agitated and making threats, requiring immediate intervention based on the least restrictive alternative doctrine.
Safety must be maintained while simultaneously respecting the client's legal and ethical rights to autonomy.
2
Identify the least restrictive, non-pharmacological interventions.
Verbal de-escalation and environmental modification (moving to an open, quiet area) are the least restrictive measures.
These interventions preserve the client's autonomy and do not involve physical or chemical coercion.
3
Sequence the pharmacological and physical interventions by restrictiveness.
Voluntary oral medications are preferred over involuntary intramuscular (IM) injections, which are in turn preferred over mechanical restraints.
The restrictiveness of an intervention increases commensurately with the loss of client autonomy and physical freedom.

Question 1703Question →

A pediatric oncology nurse is caring for a 10-year-old client with relapsed leukemia. The parents, who are divorced and share joint custody, are engaged in a hostile argument in the client's room. The mother demands the nurse restrict the father's visitation, while the father loudly questions the nurse's competence and demands to review all medications. The client is crying and covering their ears.

Arrange the following nursing actions in the correct priority sequence to de-escalate the crisis and establish therapeutic boundaries.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate psychological safety, followed by emotional de-escalation, assessment, boundary setting, and proactive planning.
In crisis intervention and family dynamics, the nurse must prioritize based on Maslow's hierarchy of needs and the nursing process. The immediate priority is the psychological safety of the client, who is actively distressed by the parents' argument. Therefore, moving the conflict out of the room is the first necessary action. Once in a private setting, the nurse must de-escalate the intense emotions through validation and active listening before any logical problem-solving can occur. After de-escalation, the nurse assesses the parents' understanding of the situation to identify knowledge gaps. With data gathered and emotions calmed, the nurse can effectively establish professional boundaries, refusing to be triangulated into their dispute. Finally, the nurse works with the interdisciplinary team to implement a structured plan that prevents future occurrences and ensures equitable communication.

Step-by-Step Solution

1
Remove the conflict from the client's environment.
The parents are moved to a private area away from the child.
The client is exhibiting signs of acute psychological trauma. Protecting the client from further emotional harm is the highest priority, aligning with safety and environmental management principles.
2
Use therapeutic communication to de-escalate the situation.
The nurse validates the parents' fear and anxiety.
De-escalation must occur before logical discussion can begin. Acknowledging their underlying fear regarding the relapse helps build rapport and reduces hostility.
3
Perform an assessment of the parents' knowledge and expectations.
The nurse gathers data on what the parents understand about the policies and treatment.
According to the nursing process, assessment follows the establishment of immediate safety and de-escalation. The nurse needs to identify the root cause of the current dispute regarding care and visitation.
4
Set clear limits and therapeutic boundaries.
The nurse clearly states the role of the healthcare team.
Firm boundaries are necessary to prevent the parents from triangulating the nurse into their marital conflict and to refocus their attention on the client's care.
5
Develop a collaborative, proactive plan.
A structured visitation and communication schedule is established.
Implementing a long-term strategy with the interdisciplinary team prevents future escalation and ensures consistent, equitable communication with both custodial parents.

Key Concept

Prioritization of care in family crises requires addressing immediate safety and environmental concerns first, followed by emotional de-escalation, assessment, boundary setting, and proactive planning.
Question 1704Question →

A hospitalized client is receiving an ongoing continuous intravenous (IV) drip of 0.9% sodium chloride. The healthcare provider orders a single dose of an IV analgesic to manage the client's acute pain. What is the most critical action for the nurse to perform immediately before injecting the analgesic into the existing IV line?

Show answer & explanation

Answer: Check a reliable drug reference to ensure the analgesic and the sodium chloride solution can be safely mixed.

Answer

Check a reliable drug reference to ensure the analgesic and the sodium chloride solution can be safely mixed.
Before administering any intravenous medication into an existing continuous infusion, the nurse must confirm that the two substances are physically and chemically compatible. This prevents the formation of precipitates, which can occlude the catheter or cause an embolism.

Step-by-Step Solution

1
Identify the primary clinical task.
The nurse needs to administer an IV push medication into an active continuous IV line.
Understanding the exact route and current IV setup is the first step in ensuring patient safety.
2
Determine the highest priority safety requirement for IV push administration.
The nurse must verify that the two fluids will not cause an adverse chemical reaction or precipitate when mixed in the IV tubing.
Incompatible IV fluids can form solid particles that act as emboli, posing a life-threatening risk to the client.
3
Select the correct nursing intervention.
Consulting a compatibility chart or drug reference is required before injecting the medication.
This action directly prevents the administration of incompatible substances into the same line.

Question 1705Question →

A home health nurse is visiting a family where an adult daughter is the primary caregiver for her mother with severe Alzheimer's disease. The daughter appears exhausted, begins to cry, and states, "I cannot do this anymore, but I promised I would never put her in a facility." Which of the following is the most appropriate initial response by the nurse?

Show answer & explanation

Answer: It sounds like you are feeling completely overwhelmed. Tell me more about what you are experiencing.

Answer

The most appropriate response is to acknowledge the caregiver's feelings and invite her to share more about her experience.
The correct answer utilizes therapeutic communication techniques by reflecting the caregiver's feelings ('feeling completely overwhelmed') and using an open-ended statement ('Tell me more'). This allows the nurse to establish a supportive relationship, validate the caregiver's distress, and thoroughly assess the extent of the caregiver strain before discussing potential interventions.

Step-by-Step Solution

1
Analyze the caregiver's statement and nonverbal behavior.
The caregiver is exhausted, crying, and expressing conflict between her limits and her prior promise.
Identifying the core issue (caregiver role strain and emotional distress) is necessary to formulate a response.
2
Evaluate the response options based on therapeutic communication principles.
Identify which option addresses the immediate emotional needs without offering premature solutions.
The priority in a psychosocial crisis is to establish trust and assess the situation fully before intervening.
3
Select the option that reflects feelings and uses open-ended exploration.
The correct response validates the caregiver's overwhelm and asks her to tell more.
This approach facilitates communication and helps the nurse assess the severity of the caregiver strain.

Question 1706Question →

A nurse discovers a client unresponsive with severe cyanosis, pinpoint pupils, and a respiratory rate of 4 breaths/minute. An empty bottle of prescription oxycodone is found on the bedside table. The nurse immediately activates the rapid response team. Arrange the following nursing actions in the correct prioritized sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first assess the pulse, then open the airway, initiate rescue breathing, administer the naloxone, and finally place the client in the recovery position.
The correct sequence strictly adheres to the American Heart Association (AHA) Basic Life Support (BLS) guidelines and the ABCs (Airway, Breathing, Circulation) of resuscitation. After establishing unresponsiveness and calling for the rapid response team, the nurse must first assess the pulse to rule out cardiac arrest. Finding a pulse but severely inadequate breathing (4 breaths/minute) indicates acute respiratory arrest. The nurse must immediately open the airway and provide rescue breathing with a BVM device. Establishing ventilation and oxygenation is the absolute highest priority to prevent anoxic brain injury. Only after the client is being actively ventilated should the nurse administer the prescribed naloxone. Finally, because naloxone causes abrupt reversal of opioid effects and can induce acute withdrawal symptoms like vomiting, placing the spontaneously breathing client in the recovery position is critical to prevent aspiration.

Step-by-Step Solution

1
Assess the carotid pulse for up to 10 seconds.
Determines the presence of circulation.
Basic Life Support (BLS) guidelines dictate assessing circulation immediately after calling for help to differentiate between respiratory arrest and cardiac arrest.
2
Open the airway using the head-tilt/chin-lift maneuver.
Clears anatomical obstruction (the tongue) from the airway.
If a pulse is present but the patient is in respiratory failure (4 breaths/min), the airway must be opened before ventilation can be successful.
3
Initiate rescue breathing using a bag-valve-mask (BVM) device connected to 100% oxygen.
Delivers essential oxygen to the lungs and brain.
Severe hypoxia is the most immediate threat to life in an opioid overdose. Mechanical ventilation takes priority over pharmacological interventions.
4
Administer the prescribed intravenous naloxone.
Reverses the effects of the opioid toxicity.
Once the client is being oxygenated, the opioid antagonist is given to reverse the underlying cause of the respiratory depression.
5
Turn the client into a side-lying (recovery) position.
Protects the airway from aspiration.
As naloxone reverses the overdose, it often precipitates acute withdrawal symptoms, including sudden vomiting. The recovery position uses gravity to keep the airway clear.

Question 1707Question →

A nurse is caring for a client who was just informed that they require a below-the-knee amputation due to severe vascular disease. The client is sitting rigidly in bed, staring blankly at the wall. Arrange the following therapeutic communication interventions in the most appropriate chronological order to establish rapport and address the client's emotional distress. (Place the initial action at the top and the final action at the bottom.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to establish presence, share an observation, utilize silence, validate expressed emotions, and finally explore specific concerns.
Effective therapeutic communication in a crisis follows a structured progression. The nurse must first establish a safe environment (presence) before inviting conversation (observation). Because the client is in shock, silence is critical to allow processing time. Once the client expresses their feelings, those emotions must be validated before the nurse can effectively explore specific concerns or move toward planning.

Step-by-Step Solution

1
Ensure privacy and sit at eye level.
Creates a safe, non-threatening environment.
Physical presence and privacy are prerequisites for vulnerable communication.
2
Make a gentle observation.
Opens the door for dialogue.
Sharing an observation is a broad opening that invites the client to share without forcing them.
3
Utilize therapeutic silence.
Provides cognitive and emotional space.
Silence prevents the nurse from dominating the conversation and allows a shocked client to process information.
4
Validate the client's feelings.
Builds trust and therapeutic rapport.
Validation demonstrates empathy and confirms that the client's emotional response is heard and accepted.
5
Use open-ended questions to explore concerns.
Identifies specific areas for nursing intervention.
Exploration is most effective after the emotional foundation is secured, allowing for focused supportive care.

Question 1708Question →

A triage nurse at a disaster relief center encounters a client who recently lost their home to a wildfire. The client is pacing erratically, hyperventilating, and shouting, 'I can't think! Everything is gone!' Arrange the following stress management and crisis interventions in the priority chronological sequence the nurse should implement them, from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: establish physical presence and safety, relocate to a low-stimulus area, use simple and firm communication, coach through physiological grounding, and finally encourage verbalization of feelings.
The correct sequence mirrors the hierarchy of needs in psychiatric crisis intervention: immediate physical/psychological safety, environmental modification, communication adjustment, physiological regulation, and lastly, emotional processing. A nurse must secure the client's fundamental physiological and safety needs before expecting higher-order cognitive functioning and emotional reflection.

Step-by-Step Solution

1
Establish immediate presence and assure safety.
The client recognizes they are not alone and are in a secure location.
A panicked client is at high risk for flight or injury; physical presence provides a fundamental anchor for psychological safety.
2
Modify the external environment.
The client is moved away from overwhelming sensory input.
External chaos directly exacerbates sensory overload and fuels the physiological stress response.
3
Adapt the communication style.
The nurse delivers clear, easily processed directives.
Acute panic drastically narrows the perceptual field, rendering the client incapable of processing complex sentences or reasoning.
4
Implement active physiological coping strategies.
The client engages in paced breathing, lowering their heart rate and respiratory rate.
Grounding techniques physically interrupt the sympathetic nervous system's fight-or-flight cascade.
5
Facilitate emotional processing.
The client begins to express grief and fear verbally.
Therapeutic processing of trauma can only be effective when the client is physiologically regulated and capable of insight.

Question 1709Question →

A home care nurse is conducting an initial visit with a 68-year-old client whose spouse was permanently transitioned to a dementia care center just hours ago. The client is pacing rapidly around the empty house, crying uncontrollably, and remarks, "I betrayed my vow to keep them at home. I am completely worthless now. There is simply no point in me waking up tomorrow without them here." Which of the following is the priority nursing action?

Show answer & explanation

Answer: Determine whether the client has formulated a specific plan to end their life.

Answer

The priority action is to determine whether the client has formulated a specific plan to end their life.
During a severe situational crisis, the client's emotional distress can precipitate self-harm. The client's statement, "There is simply no point in me waking up tomorrow," is a strong indicator of potential suicidal ideation. During any crisis intervention, ensuring client safety is always the absolute highest priority. Before implementing broad psychological support, rationalizing the event, or exploring past coping strategies, the nurse must explicitly assess the lethality and specificity of the client's thoughts of self-harm.

Step-by-Step Solution

1
Analyze the client's verbal statements for covert or overt safety risks.
The phrase "There is simply no point in me waking up tomorrow" is a significant cue indicating potential suicidal ideation.
Recognizing safety threats is the first step in clinical prioritization during a crisis.
2
Apply the principles of crisis intervention and clinical prioritization.
Client safety outranks all other interventions, including emotional validation, psychological stabilization, and assessment of coping skills.
According to Maslow's Hierarchy of Needs and standard safety protocols, preservation of life is the foundational priority.
3
Select the nursing action that directly addresses the highest priority need.
The action that directly assesses the lethality and presence of a suicide plan is the correct choice.
Direct assessment of self-harm intent allows the nurse to immediately implement life-saving precautions if necessary.

Question 1710Question →

A client undergoing inpatient rehabilitation for a substance use disorder tells the nurse, "I wouldn't need to use drugs if my boss didn't put so much pressure on me at work." Which of the following is the most appropriate therapeutic response by the nurse?

Show answer & explanation

Answer: It sounds like you are attributing your substance use to the stress you experience at work.

Answer

The most appropriate therapeutic response is to restate and reflect the client's statement, noting that they are attributing their substance use to work stress.
Restating or reflecting the client's message is a highly effective therapeutic communication technique. In substance use disorder treatment, clients frequently use defense mechanisms like projection or rationalization to avoid taking responsibility for their addiction. By neutrally reflecting the client's statement, the nurse acts as a mirror, encouraging the client to examine their own coping mechanisms and begin taking ownership of their choices without causing immediate defensiveness.

Step-by-Step Solution

1
Analyze the client's statement to identify underlying themes or defense mechanisms.
The client is using rationalization and projection, blaming an external factor (the boss) for their decision to use substances.
Recognizing defense mechanisms is a fundamental component of psychiatric nursing, especially in addiction treatment where denial is common.
2
Evaluate the response options based on established principles of therapeutic communication.
Identify the response that reflects the client's feelings without judging, giving advice, asking 'why', or providing false reassurance.
Therapeutic communication aims to facilitate the client's self-exploration and personal responsibility in a safe environment.

Question 1711Question →

A client with a history of severe major depressive disorder presents to an outpatient psychiatric clinic for a follow-up appointment. The client has been taking a prescribed selective serotonin reuptake inhibitor (SSRI) for four weeks. The nurse notes the client appears uncharacteristically calm, smiles softly, and hands the nurse a sealed envelope, stating, 'I will not be needing to come back here. I have finally found the permanent solution to my struggles.' Which of the following is the priority response by the nurse?

Show answer & explanation

Answer: You mentioned finding a permanent solution. Are you planning to commit suicide?

Answer

The nurse must directly ask the client about suicidal ideation or intent to self-harm.
The client's presentation—a sudden shift to a calm affect, handing over an envelope, and making statements about a 'permanent solution' after four weeks of SSRI therapy—strongly indicates a high risk for imminent suicide. Antidepressants can increase energy levels before fully alleviating depressive cognitive symptoms, providing the client with the motivation and energy to carry out a lethal plan. The priority action is to ensure safety by directly and clearly asking the client about suicidal ideation.

Step-by-Step Solution

1
Analyze the client's clinical presentation and timeline.
The client has been on an SSRI for four weeks, exhibits a sudden shift to a calm affect, is giving away a sealed envelope, and speaks of a 'permanent solution'.
Recognizing the timeline of antidepressant therapy is critical, as it often provides the energy to carry out a suicide plan before the severe depressed mood fully lifts.
2
Determine the priority nursing action based on the assessment.
The immediate priority is to assess for the presence of a suicide plan and intent.
Client safety is the highest priority (Maslow's hierarchy/safety and security). When covert or overt signs of suicide are present, the nurse must ask direct, unequivocal questions about self-harm.

Question 1712Question →

A client on the postpartum unit delivered a newborn yesterday. The infant was unexpectedly transferred to the neonatal intensive care unit (NICU) due to respiratory distress. The client is observed pacing the room and meticulously organizing the bedside table. The client asks the nurse, "What is the exact calibration frequency for the neonatal continuous positive airway pressure machine?" The client displays a flat affect and shows no visible emotional distress regarding the separation. Which of the following nursing interventions are most appropriate to support the client's coping? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Answer the client's inquiries about the medical equipment using clear and factual terminology.; Offer to accompany the client to the intensive care unit to visit the newborn.; Provide an open-ended opportunity for the client to discuss their feelings when ready.

Answer

The appropriate interventions are to answer inquiries with factual terminology, offer to accompany the client to the NICU, and provide an open-ended opportunity to discuss feelings.
The client is utilizing intellectualization to cope with the trauma of an unexpected NICU admission. In the acute phase of a crisis, defense mechanisms serve a protective function. The nurse should support the client by providing the factual information they seek, offering a non-judgmental presence, and gently facilitating reality orientation (such as visiting the NICU) at a pace the client can emotionally tolerate.

Step-by-Step Solution

1
Analyze the client's behavioral cues and clinical presentation.
The client is pacing, focusing on highly technical details regarding medical equipment, and displaying a flat affect despite an acute, stressful event (NICU transfer).
Identifying the underlying emotional state and behavioral patterns is necessary to determine the coping mechanism being utilized.
2
Identify the specific defense mechanism the client is employing.
The client is using intellectualization, separating emotions from a stressful event by focusing exclusively on facts, logic, and technical data.
Understanding the specific defense mechanism guides the selection of safe and therapeutic nursing interventions.
3
Evaluate each nursing intervention for therapeutic value and safety.
Supporting the defense mechanism initially, providing presence, and encouraging gradual reality confrontation are therapeutic. Direct confrontation, false reassurance, and probing 'why' questions are non-therapeutic.
Nursing care must support adaptive coping while strictly avoiding communication blocks that increase client anxiety.

Question 1713Question →

A nurse is preparing to draw a blood sample for laboratory testing from a client's central venous catheter (CVC). To reduce the risk of infection and ensure accurate laboratory results, arrange the following nursing actions in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: perform hand hygiene and don gloves, scrub the catheter hub, check patency by aspirating and flushing, discard the waste blood volume, and finally obtain the pure blood sample.
Following this exact procedural sequence prioritizes client safety by minimizing the risk of central line-associated bloodstream infections (CLABSI) and preventing the reporting of inaccurate laboratory values. Infection control (hand hygiene and scrubbing the hub) must always occur first. Next, verifying patency and flushing ensures the line is functional. Crucially, the nurse must then withdraw and discard the initial 'waste' blood to clear the line of any residual IV fluids or medications. Finally, a pristine, undiluted sample is drawn using a new syringe.

Step-by-Step Solution

1
Initiate baseline infection control measures.
Hand hygiene is performed and clean gloves are donned.
To establish a clean environment and protect the client from exogenous pathogens.
2
Disinfect the access port.
The central line hub is scrubbed vigorously with an antimicrobial swab.
To mechanically remove and eliminate surface bacteria, minimizing the direct risk of introducing a central line-associated bloodstream infection (CLABSI).
3
Verify line patency and clear the line.
The nurse aspirates for a blood return and flushes the line with normal saline.
To confirm the central line is functioning properly and is free of occlusions or incompatible fluids before drawing blood.
4
Clear the catheter dead space.
A specific volume of blood is withdrawn and safely discarded.
To remove any residual medications or saline in the catheter that could dilute the blood sample, ensuring the laboratory results accurately reflect the client's systemic condition.
5
Collect the diagnostic specimen.
A new syringe is attached to draw the necessary volume for the prescribed laboratory tests.

Question 1714Question →

A client is brought to the emergency department with a decreased level of consciousness, deep and rapid respirations, and a fruity breath odor. Laboratory results confirm a diagnosis of diabetic ketoacidosis (DKA) with a blood glucose level of 680 mg/dL. Arrange the following collaborative and nursing interventions in the chronological order they should be implemented.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Establish intravenous access and infuse 0.9% sodium chloride, 2) Evaluate the client's initial serum potassium level, 3) Initiate a continuous intravenous infusion of regular insulin, and 4) Add 5% dextrose to the intravenous maintenance fluids.
The priority in DKA is restoring intravascular volume to ensure adequate organ perfusion. After initiating fluids, the potassium level must be checked because insulin therapy will lower serum potassium. Once potassium is confirmed safe, regular insulin is infused to reverse the ketoacidosis. Finally, when blood glucose drops to approximately 250 mg/dL, dextrose is added to prevent hypoglycemia while insulin continues to clear blood ketones.

Step-by-Step Solution

1
Determine the most immediate life-threatening physiological need for a client with DKA.
Severe dehydration and intravascular volume depletion are identified as the primary threats.
Extreme hyperglycemia causes osmotic diuresis, leading to massive fluid loss that must be corrected immediately to prevent cardiovascular collapse.
2
Select the prerequisite assessment required before treating the hyperglycemia.
Evaluate the serum potassium level.
Insulin therapy drives both glucose and potassium into the intracellular space. If the client is already hypokalemic, giving insulin can precipitate life-threatening cardiac arrhythmias.
3
Identify the primary pharmacological intervention to reverse the ketoacidosis.
Initiate a continuous intravenous infusion of regular insulin.
With fluids running and potassium levels confirmed safe, intravenous regular insulin is administered to stop ketogenesis and safely lower the blood glucose level.
4
Anticipate necessary modifications to therapy as the client's condition improves.
Add 5% dextrose to the intravenous fluids when blood glucose reaches approximately 250 mg/dL.
This action prevents treatment-induced hypoglycemia and cerebral edema, allowing the insulin infusion to continue until the acidosis is fully resolved.

A nurse in the intensive care unit is caring for a critically ill adult client who does not have an advance directive. Two of the client's adult siblings begin arguing loudly in the hallway regarding who should make the medical decisions. Which nursing actions are appropriate to manage this family dynamic? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Invite the siblings into a quiet consultation room to discuss their concerns.; Acknowledge their distress and validate that having a critically ill family member is overwhelming.; Offer to collaborate with the hospital social worker to facilitate a structured family meeting.

Answer

The correct actions are to invite the siblings to a private room, acknowledge their distress, and offer the assistance of a social worker for a family meeting.
The correct nursing actions prioritize therapeutic communication, emotional support, and interdisciplinary collaboration. Moving the family to a private area respects their privacy while maintaining a quiet environment for the unit. Validating their emotions builds rapport, and consulting a social worker provides the specialized mediation needed to handle complex medical decisions when no advance directive exists.

Step-by-Step Solution

1
Analyze the family dynamic and immediate environment.
The siblings are experiencing high stress due to the critical illness and lack of an advance directive, resulting in a loud public conflict.
Understanding the root cause of the conflict (situational crisis) guides the nurse toward supportive rather than punitive interventions.
2
Determine the priority interventions for de-escalation.
The immediate goal is to relocate the conflict away from the clinical care area to a private setting while offering emotional validation.
Protecting the therapeutic environment for all clients while respecting the family's need to process their distress is essential.
3
Evaluate long-term strategies to support family decision-making.
Involving the interdisciplinary team (e.g., social work) is identified as the best approach to resolve the underlying decision-making dispute.
Nurses facilitate resources but do not make personal medical decisions for the family.

Question 1716Question →

A nurse is caring for a client in the emergency department who has just experienced a spontaneous abortion at 10 weeks of gestation. The client is crying and states, "If only I had not gone for that long run yesterday, my baby would still be alive." Which of the following is the most therapeutic response by the nurse?

Show answer & explanation

Answer: It sounds like you are feeling responsible for the loss of your baby.

Answer

The most therapeutic response reflects the client's feelings of responsibility and guilt, stating, "It sounds like you are feeling responsible for the loss of your baby."
The correct response uses the therapeutic technique of reflection. By restating the core emotion (feeling responsible), the nurse validates the client's feelings of guilt and grief. This opens the door for the client to explore their emotions further in a safe, non-judgmental environment. It addresses the emotional need before attempting to provide medical education.

Step-by-Step Solution

1
Analyze the client's statement and emotional state.
The client is experiencing acute grief and expressing profound guilt, erroneously blaming a recent physical activity for the spontaneous abortion.
Understanding the core emotion (guilt/grief) is essential for selecting a response that addresses the client's immediate psychological needs.
2
Evaluate the nursing responses based on therapeutic communication principles.
Responses providing medical facts, reassurance, or asking 'why' fail to validate the client's current emotional distress. The response that reflects the client's feelings acknowledges the emotion without agreeing with the incorrect premise.
Therapeutic communication prioritizes the validation of the client's feelings over providing immediate education, reassurance, or rationalization.

The client's cardiac monitor suddenly displays widening QRS complexes. The healthcare provider verbally prescribes an emergent IV bolus of 10%10\% calcium gluconate (1000 mg1000\text{ mg}) to stabilize the myocardium. The client currently has no peripheral IV access. Which of the following actions is the most appropriate for the nurse to take?

Show answer & explanation

Answer: Administer the calcium gluconate via the injection port of the medial lumen's IV tubing closest to the client, allowing the 0.9% sodium chloride to act as a carrier fluid.

Answer

The most appropriate action is to administer the calcium gluconate via the medial lumen, utilizing the continuous 0.9% sodium chloride as a compatible carrier fluid.
The correct action is to administer the calcium gluconate via the medial lumen. The medial lumen contains 0.9% sodium chloride, which is fully compatible with calcium gluconate. Crucially, because the separate lumens of a CVC act as independent catheters with staggered exit ports in the superior vena cava, the calcium exiting the medial port will instantly dilute in the rapid central venous blood flow, preventing it from precipitating with the sodium bicarbonate exiting the distal port. Using this lumen ensures immediate, safe administration without interrupting necessary ongoing therapies or risking an accidental bolus of insulin.

Step-by-Step Solution

1
Analyze the clinical emergency.
The client has hyperkalemia with widening QRS complexes, indicating impending ventricular fibrillation.
Immediate administration of calcium gluconate is required to stabilize the myocardial threshold. Delaying for peripheral IV access is contraindicated.
2
Evaluate the compatibility of the prescribed medication with the current infusions.
Calcium gluconate is highly incompatible with sodium bicarbonate (forms a chalky precipitate). It is compatible with 0.9% sodium chloride.
Identifying chemical incompatibilities prevents catastrophic line occlusion and embolization of precipitates.
3
Assess the multi-lumen CVC physiology and existing infusions.
The distal lumen has bicarbonate, the proximal has a high-alert insulin drip, and the medial has compatible normal saline. Separate CVC lumens act as completely independent IV lines.
Because CVC lumens exit at different points in the high-volume superior vena cava, incompatible drugs will instantly dilute in the blood without precipitating, eliminating the need for separate catheter insertion sites.
4
Select the safest lumen for IV push administration.
The medial lumen is selected.
It avoids mixing with bicarbonate (distal) and avoids flushing the dead space of the insulin line (proximal), which would cause a dangerous hypoglycemic bolus.

Key Concept

Multi-lumen central venous catheters (CVCs) function as completely independent intravenous lines, safely allowing the concurrent infusion of physically incompatible medications. Furthermore, medications should never be pushed through the tubing of a continuous high-alert medication due to the risk of delivering an unintended bolus from the tubing's dead space.

A nurse is caring for a critically ill client who has a multi-lumen central venous catheter (CVC) in place. The client is receiving a continuous intravenous (IV) vasopressor infusion. Which of the following actions by the nurse demonstrate safe parenteral therapy and catheter management? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: Scrub the needleless connector hub with an appropriate antiseptic for at least 15 seconds before accessing.; Use a syringe with a barrel size of 10 mL or larger when flushing the catheter lumens.; Clamp any unused catheter lumens securely when they are not actively being used.

Answer

The safe parenteral therapy practices are scrubbing the connector hub for at least 15 seconds, using a syringe with a 10 mL or larger barrel for flushing, and clamping unused lumens.
Safe central venous catheter management requires strict infection control (scrubbing the hub), preventing catheter damage (using at least a 10 mL syringe to avoid high pressure), and preventing air embolisms and blood reflux (clamping unused lumens).

Step-by-Step Solution

1
Evaluate the risk of infection.
Scrubbing the hub for 15 seconds is required to prevent CLABSI.
Central lines provide direct access to the central circulation, making infection prevention paramount.
2
Evaluate the physical maintenance of the catheter.
A 10 mL or larger syringe must be used for flushing, and unused lumens must be clamped.
Smaller syringes create high pressure that can rupture the line, and unclamped lumens risk air embolism or blood reflux.
3
Evaluate medication administration and delegation practices.
Incompatible medications cannot share a lumen, vasopressors must not be paused, UAPs cannot perform sterile dressing changes, and air embolisms require the left lateral Trendelenburg position.
These actions prevent hemodynamic instability, precipitation of medications, scope of practice violations, and catastrophic circulatory compromise.

Question 1719Question →

A nurse is performing a comprehensive physical assessment on a 72-year-old client admitted to the medical-surgical unit with suspected dehydration and generalized fatigue. Which action by the nurse demonstrates the correct execution of physical assessment principles?

Show answer & explanation

Answer: Assessing for fluid volume deficit by gently pinching the skin over the client's clavicle to observe for tenting.

Answer

The correct action is assessing for fluid volume deficit by gently pinching the skin over the client's clavicle to observe for tenting.
In older adults, the skin loses elasticity and subcutaneous fat, making the back of the hand an unreliable site for assessing hydration. The correct technique for assessing skin turgor in an older client is to pinch the skin over the clavicle or sternum to accurately observe for tenting, which is a clinical indicator of dehydration.

Step-by-Step Solution

1
Analyze the client's demographic profile (72 years old) and the clinical presentation (suspected dehydration).
The nurse must select physical assessment techniques that account for age-related physiological changes.
Standard assessment sites, such as the back of the hand, become unreliable in older adults due to the natural loss of skin elasticity and subcutaneous fat.
2
Evaluate the correct technique for assessing tissue turgor in the geriatric population.
The skin over the clavicle or sternum is the most reliable site for assessing turgor in older clients.
The skin over the chest remains relatively taut despite aging, making it an accurate indicator of true fluid volume deficit (tenting).
3
Rule out assessment approaches that violate procedural standards, delegation rules, or physiological principles.
Abdominal palpation must follow auscultation, initial assessments cannot be delegated, and sudden confusion must be treated as acute delirium rather than normal aging.
Adhering strictly to established nursing protocols ensures accurate data collection and protects the client from harm.

Question 1720Question →

An adult client is being treated for a pulmonary embolism and is currently receiving a continuous intravenous heparin infusion at 15 units/kg/hr15 \text{ units/kg/hr}. The client weighs 198 lbs198 \text{ lbs}. The infusion bag supplied by the pharmacy contains 25,000 units25,000 \text{ units} of heparin in 500 mL500 \text{ mL} of 5%5\% Dextrose in Water (D5W). The client's most recent activated partial thromboplastin time (aPTT) result is 41 seconds41 \text{ seconds}.

The facility's heparin adjustment protocol states:

aPTT ResultRequired Action
<35 seconds< 35 \text{ seconds}Bolus 80 units/kg80 \text{ units/kg}, increase infusion by 4 units/kg/hr4 \text{ units/kg/hr}

Based on the protocol, at what rate in mL/hr\text{mL/hr} should the nurse set the infusion pump for the continuous maintenance drip? (Record your answer to the nearest tenth.)

Show answer & explanation

Answer: 30.6

Answer

30.6
The correct pump rate is derived by first converting the client's weight to kilograms (198 lbs÷2.2=90 kg198 \text{ lbs} \div 2.2 = 90 \text{ kg}). Based on the aPTT result of 41 seconds41 \text{ seconds}, the protocol requires increasing the current infusion rate (15 units/kg/hr15 \text{ units/kg/hr}) by 2 units/kg/hr2 \text{ units/kg/hr}, making the new rate 17 units/kg/hr17 \text{ units/kg/hr}. Multiplying this by the client's weight yields a total hourly dose of 1530 units/hr1530 \text{ units/hr}. Dividing this hourly dose by the concentration of the IV solution (50 units/mL50 \text{ units/mL}) gives the required continuous pump rate of 30.6 mL/hr30.6 \text{ mL/hr}.

Step-by-Step Solution

1
Convert the client's weight from pounds to kilograms.
198 lbs÷2.2 lbs/kg=90 kg198 \text{ lbs} \div 2.2 \text{ lbs/kg} = 90 \text{ kg}
Heparin dosing is weight-based in kilograms, so an accurate conversion is the foundational step for safe medication administration.
2
Determine the required protocol action based on the aPTT result.
The aPTT is 41 seconds41 \text{ seconds}, which falls into the 36−44 seconds36 - 44 \text{ seconds} range. The protocol requires an increase of the continuous infusion by 2 units/kg/hr2 \text{ units/kg/hr}.
Protocols standardize medication titration based on objective laboratory data to achieve a therapeutic window.
3
Calculate the new total hourly heparin dose.
Current rate (15 units/kg/hr15 \text{ units/kg/hr}) + Increase (2 units/kg/hr2 \text{ units/kg/hr}) = New rate (17 units/kg/hr17 \text{ units/kg/hr}). Total hourly dose = 17 units/kg/hr×90 kg=1530 units/hr17 \text{ units/kg/hr} \times 90 \text{ kg} = 1530 \text{ units/hr}.
The adjustment must be added to the baseline rate before calculating the total weight-based hourly dose.
4
Calculate the concentration of the available heparin bag.
25,000 units÷500 mL=50 units/mL25,000 \text{ units} \div 500 \text{ mL} = 50 \text{ units/mL}
Establishing the exact concentration is necessary to convert the ordered dose (units) into a fluid volume (mL).
5
Calculate the new infusion pump rate in mL/hr.
1530 units/hr÷50 units/mL=30.6 mL/hr1530 \text{ units/hr} \div 50 \text{ units/mL} = 30.6 \text{ mL/hr}. (Already at the nearest tenth).
Dividing the desired hourly dose by the concentration yields the exact programming parameter for the intravenous pump.
