A client in the intensive care unit is receiving a continuous intravenous (IV) infusion of norepinephrine at 12 mcg/min12 \text{ mcg/min} via a single-lumen peripherally inserted central catheter (PICC) for septic shock. The client's current mean arterial pressure (MAP) is 64 mmHg64 \text{ mmHg}. The healthcare provider prescribes a stat dose of IV push hydrocortisone. Which action by the nurse is the most appropriate?

Show answer & explanation

Answer: Establish a separate peripheral intravenous catheter to administer the hydrocortisone.

Answer

The most appropriate action is to establish a separate peripheral intravenous catheter to administer the hydrocortisone.
Vasoactive medications like norepinephrine have a very short half-life and potent hemodynamic effects. They require a dedicated intravenous line to maintain a steady, precisely titrated state. Flushing the line or pushing medications through the same lumen displaces the highly concentrated vasopressor residing in the catheter's dead space, delivering a rapid, potentially lethal bolus to the client. Additionally, pausing the infusion causes immediate hypotension. Therefore, the safest action is to establish a new peripheral intravenous catheter for any additional medications.

Step-by-Step Solution

1
Analyze the client's current physiological status and intravenous access.
The client is in septic shock with a borderline MAP (64 mmHg64 \text{ mmHg}), entirely dependent on a continuous norepinephrine infusion running through a single-lumen central line.
Understanding the client's hemodynamic fragility is necessary to evaluate the safety of altering the vasoactive infusion.
2
Evaluate the fluid dynamics of administering an IV push medication into a continuous vasopressor line.
Pushing a medication or flushing the line will rapidly force the concentrated norepinephrine residing in the catheter lumen into the client's systemic circulation.
This unintended bolus can cause life-threatening hypertension and arrhythmias, while pausing the infusion removes life-sustaining vascular support.
3
Determine the safest route for administering the stat medication.
The nurse must leave the single-lumen PICC undisturbed to maintain continuous hemodynamic stability and start a new peripheral IV catheter for the hydrocortisone.
Vasoactive continuous infusions must have a dedicated line to ensure safe, uninterrupted delivery without bolus effects.

Key Concept

Safe administration of parenteral therapies requires a dedicated intravenous line for continuous vasoactive medications (like norepinephrine) to prevent unintended boluses and sudden hemodynamic collapse.
Question 2962Question →

A nurse is evaluating the arterial blood gas (ABG) results for a client who is experiencing shallow breathing and lethargy following abdominal surgery. The laboratory report displays a pH of 7.267.26, a PaCO2\text{PaCO}_2 of 58 mm Hg58\text{ mm Hg}, and an HCO3−\text{HCO}_3^- of 24 mEq/L24\text{ mEq/L}. Which of the following acid-base imbalances should the nurse identify to initiate appropriate risk-reduction interventions?

Show answer & explanation

Answer: Uncompensated respiratory acidosis

Answer

The correct acid-base imbalance is uncompensated respiratory acidosis.
The client's ABG results demonstrate uncompensated respiratory acidosis because the pH is low (indicating acidemia), the PaCO2\text{PaCO}_2 is elevated (confirming a respiratory cause), and the HCO3−\text{HCO}_3^- is within the normal range (indicating a lack of metabolic compensation).

Step-by-Step Solution

1
Analyze the pH value.
The pH is 7.267.26, which signifies an acidotic state.
A normal blood pH ranges from 7.357.35 to 7.457.45. A value below 7.357.35 clearly indicates acidosis.
2
Analyze the PaCO2\text{PaCO}_2 value.
The PaCO2\text{PaCO}_2 is elevated at 58 mm Hg58\text{ mm Hg}.
A normal PaCO2\text{PaCO}_2 is 3535 to 45 mm Hg45\text{ mm Hg}. An elevated level reflects hypoventilation and retention of carbon dioxide, confirming the respiratory origin of the acidosis.
3
Analyze the HCO3−\text{HCO}_3^- value.
The HCO3−\text{HCO}_3^- is normal at 24 mEq/L24\text{ mEq/L}.
A normal HCO3−\text{HCO}_3^- is 2222 to 26 mEq/L26\text{ mEq/L}. Because this value has not elevated to buffer the acidic pH, metabolic compensation has not yet occurred.

Question 2963Question →

A nurse is caring for a client who is receiving a packed red blood cell (PRBC) transfusion. Fifteen minutes after the transfusion begins, the client reports sudden lower back pain, chills, and shortness of breath. In which order should the nurse perform the following actions? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

Stop the transfusion, initiate normal saline with new tubing, assess the client, notify the provider and blood bank, and return the blood product to the blood bank.
The absolute priority when a transfusion reaction is suspected is to prevent further exposure to the blood product, maintain venous access, assess the client, and obtain medical intervention. Stopping the transfusion immediately is always the first step, followed by maintaining the intravenous line with 0.9% sodium chloride through entirely new tubing to prevent infusing residual blood. Next, assessing the client provides critical baseline data for the healthcare provider. Notifying the provider and blood bank allows for rapid emergency interventions. Finally, returning the blood bag and tubing allows the facility to analyze the cause of the reaction.

Step-by-Step Solution

1
Stop the blood transfusion immediately.
Further entry of incompatible blood into the client's circulation is halted.
This is the most critical first step to minimize the severity of the physiological reaction.
2
Disconnect the blood tubing and initiate an infusion of 0.9% sodium chloride using new tubing.
A patent intravenous line is maintained with a neutral fluid.
Intravenous access is critical for administering emergency medications. New tubing must be used so that the blood remaining in the old tubing is not flushed into the client.
3
Assess the client's vital signs and respiratory status.
Baseline data regarding the client's physiological decompensation is gathered.
The nurse needs current, accurate assessment data to communicate the severity of the reaction to the provider.
4
Notify the healthcare provider and the facility blood bank.
The medical team is alerted and emergency orders can be obtained.
The provider will need to prescribe interventions based on the assessment, and the blood bank must initiate their transfusion reaction protocol.
5
Return the blood bag and administration set to the blood bank.
The implicated blood product is secured for laboratory analysis.
The blood bank needs the bag, the remaining blood, and the tubing to test for crossmatching errors or bacterial contamination.

Question 2964Question →

A nurse is teaching a client with a left tibial fracture, who is prescribed non-weight-bearing status on the left leg, how to safely stand up from a seated position in a chair using axillary crutches. Arrange the following instructional steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: slide forward to the edge of the chair, place both crutches in the hand on the affected side, grasp the armrest with the unaffected hand, push up to a standing position, and finally establish a tripod stance.
When assisting a non-weight-bearing client to stand with crutches, safety and balance depend on proper leverage. The client must first move to the edge of the chair to align their center of gravity over their base of support. By placing both crutches in the hand on the affected side, the strong, unaffected arm is left free to grasp the solid chair armrest. The client then pushes up using the strong arm and strong leg, ensuring no weight is placed on the affected side. Only after achieving a stable standing position should the client move one crutch to the other hand to create the tripod stance for safe ambulation.

Step-by-Step Solution

1
Analyze the biomechanical requirements for standing from a seated position with one non-weight-bearing extremity.
The client needs to maximize leverage using their strong limbs while protecting the injured leg.
Understanding the core goal ensures each procedural step contributes to safety, stability, and adherence to weight-bearing restrictions.
2
Determine the initial positioning of the client in the chair.
The first essential step is sliding forward to the edge of the chair.
This brings the center of mass closer to the base of support, facilitating upward momentum without straining.
3
Identify the correct placement of the assistive devices and hands before attempting to stand.
Both crutches should be placed in the hand on the affected side, and the unaffected hand should grasp the armrest.
This configuration leaves the strong, unaffected arm free to push off the solid armrest, providing maximum upward leverage.
4
Sequence the remaining actions to achieve a safe, upright position.
The client pushes up using the armrest and strong leg, and only then transfers one crutch to the other side.
Establishing the tripod stance can only safely occur once the client is fully upright and balanced on the strong leg; attempting this while seated is unstable.

Question 2965Question →

While performing a clinical assessment on a client who underwent an open splenectomy four hours ago, the nurse reviews the electronic health record. The baseline vital signs recorded upon arrival to the surgical unit were: blood pressure 128/72 mm Hg, heart rate 76 beats/min, and respiratory rate 16 breaths/min. Which of the following current clinical findings should the nurse interpret as the earliest sign of impending physiological decompensation that necessitates immediate risk mitigation?

Show answer & explanation

Answer: A blood pressure of 110/86 mm Hg and a heart rate of 104 beats/min

Answer

The finding of a blood pressure of 110/86 mm Hg and a heart rate of 104 beats/min provides the earliest indication of impending physiological decompensation.
The correct answer identifies a narrowing pulse pressure and mild tachycardia. The pulse pressure has decreased from 56 mm Hg at baseline to 24 mm Hg, and the heart rate has correspondingly increased. Because the spleen is a highly vascular organ, an open splenectomy carries a significant risk of postoperative hemorrhage. These subtle vital sign changes reflect the body's compensatory mechanisms (sympathetic nervous system activation causing vasoconstriction and tachycardia) in early hypovolemic shock, which requires immediate fluid resuscitation and provider notification to mitigate severe risk.

Step-by-Step Solution

1
Analyze the baseline vital signs provided in the vignette.
Baseline BP is 128/72 mm Hg (pulse pressure = 56 mm Hg) and HR is 76 beats/min.
Establishing a baseline is essential for identifying physiological trends and deterioration.
2
Evaluate the current blood pressure and heart rate option against the baseline.
The current BP is 110/86 mm Hg, yielding a narrowed pulse pressure of 24 mm Hg, alongside a tachycardic HR of 104 beats/min.
Comparing current values to baseline helps detect the compensatory mechanisms of shock, specifically sympathetic nervous system activation causing peripheral vasoconstriction.
3
Evaluate the other assessment findings for clinical significance.
Urine output of 35 mL/hr is acceptable; low-grade fever is an expected inflammatory response; minor serosanguineous drainage is normal post-operatively.
Discriminating between expected post-operative variances and signs of acute decompensation ensures correct prioritization and risk mitigation.

Question 2966Question →

A nurse at a menopause specialty clinic is evaluating a 54-year-old client's understanding of lifestyle modifications aimed at osteoporosis risk reduction. Which statements by the client indicate effective learning? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Engaging in brisk walking for at least 30 minutes most days of the week will help preserve my bone strength.; I plan to increase my daily intake of low-fat dairy products, tofu, and calcium-fortified beverages.; I have enrolled in a behavioral support program to help me completely quit smoking cigarettes.

Answer

The correct statements are engaging in brisk walking, increasing intake of calcium-rich foods, and quitting smoking.
Effective lifestyle choices for minimizing osteoporosis risk involve actively modifying controllable factors. This includes engaging in regular weight-bearing exercise to stimulate bone formation, ensuring adequate dietary calcium intake, and eliminating toxic habits like smoking that accelerate bone demineralization.

Step-by-Step Solution

1
Analyze the clinical goal presented in the scenario.
The client needs to identify daily lifestyle modifications that actively reduce the risk of developing osteoporosis.
Understanding the goal helps differentiate true health promotion strategies from passive monitoring or harmful behaviors.
2
Evaluate the statements regarding physical activity, diet, and habits.
Brisk walking (which is weight-bearing), eating calcium-rich foods, and quitting smoking are all evidence-based, positive lifestyle choices that directly address modifiable risk factors for bone demineralization.
These actions actively build bone density or remove factors that accelerate bone loss.
3
Evaluate the statements regarding disease prevention and aging expectations.
Classifying a DEXA scan as primary prevention is incorrect (it is a secondary screening), and assuming severe back pain is just normal aging ignores a potential pathologic fracture.
Accurately distinguishing between primary prevention and screening, as well as between normal aging and acute pathology, is vital for safe self-care and disease management.

Key Concept

Effective lifestyle choices for osteoporosis risk reduction include weight-bearing exercises, adequate dietary calcium intake, and smoking cessation. Clients must also correctly differentiate between primary prevention (active risk reduction) and secondary prevention (screening).
Question 2967Question →

A nurse is caring for an older adult client who is 1 day post-operative following an abdominal surgery. The provider has prescribed knee-high antiembolism stockings to promote venous return. Which of the following actions should the nurse take?

Show answer & explanation

Answer: Measure the circumference of the client's calf at its widest point and the leg length from the heel to the popliteal fold to determine the correct size.

Answer

The nurse should measure the circumference of the client's calf at its widest point and the leg length from the heel to the popliteal fold to determine the correct stocking size.
To ensure antiembolism stockings provide the correct amount of graduated compression without impeding circulation, the nurse must accurately measure the client's legs. For knee-high stockings, this involves measuring the calf circumference at the widest point and the length from the bottom of the heel to the popliteal fold. Properly sized stockings promote venous return and prevent complications like deep vein thrombosis.

Step-by-Step Solution

1
Identify the client's risk factors and the provider's prescription.
The client is post-operative and requires knee-high antiembolism stockings to prevent deep vein thrombosis (DVT).
Ensures the correct intervention is being prepared based on the client's specific clinical needs.
2
Determine the necessary preparation steps for applying the stockings safely.
Accurate measurement of the client's legs is required before application.
Stockings that are too tight can restrict arterial blood flow, while those that are too loose will not provide adequate venous compression.
3
Evaluate the remaining options for safety and adherence to the nursing scope of practice.
Delegating initial assessments, ignoring acute confusion, and placing pressure on the popliteal space are all unsafe or incorrect actions.
Eliminating contraindicated interventions isolates the correct, evidence-based nursing action.

Question 2968Question →

A nurse is evaluating a client at 35 weeks gestation who arrived at the emergency department following a high-speed motor vehicle collision. The client reports mild, continuous abdominal discomfort but denies any visible vaginal bleeding. Which of the following assessment findings should the nurse identify as indicators of a concealed placental abruption and impending hemorrhagic shock? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Maternal resting heart rate of 118 beats per minute; A rigid, board-like abdomen upon palpation; Fetal heart rate baseline of 175 beats per minute

Answer

The correct findings are a maternal resting heart rate of 118 beats per minute, a rigid and board-like abdomen, and a fetal heart rate baseline of 175 beats per minute.
Concealed placental abruption occurs when the placenta separates from the uterine wall but the margins remain attached, trapping the bleeding. This concealed hemorrhage increases uterine resting tone, leading to a classic rigid, board-like abdomen. As blood is lost into the uterine cavity, the mother's body compensates for the hypovolemia by increasing her heart rate (tachycardia). Concurrently, the reduced maternal blood volume compromises uteroplacental perfusion, leading to early fetal hypoxia, which typically manifests as fetal tachycardia (a baseline greater than 160 beats per minute).

Step-by-Step Solution

1
Analyze the clinical scenario
The client has experienced blunt force abdominal trauma (motor vehicle collision) and is reporting continuous discomfort without visible bleeding, which is highly suspicious for a concealed placental abruption.
Trauma is a major risk factor for placental abruption, and the absence of external vaginal bleeding does not rule out internal (concealed) hemorrhage.
2
Identify direct signs of concealed hemorrhage
A rigid, board-like abdomen occurs because blood trapped behind the placenta infiltrates the myometrium, significantly increasing uterine resting tone.
This is the primary physical manifestation of concealed bleeding within the uterus.
3
Identify early systemic signs of hypovolemic shock in the mother
A maternal heart rate of 118 bpm (tachycardia) is an early compensatory sign. A widening pulse pressure is an incorrect finding (it should narrow), and a urine output of 45 mL/hr is completely normal.
The body compensates for acute blood loss by increasing the heart rate and inducing peripheral vasoconstriction before the systolic blood pressure drops significantly.
4
Identify early signs of fetal hypoxia
A fetal heart rate baseline of 175 bpm (tachycardia) indicates early hypoxia due to compromised uteroplacental perfusion. Early decelerations are benign and unrelated to hypoxia.
The fetus responds to initial hypoxemia with sympathetic nervous system stimulation, causing a sustained elevation in the baseline heart rate.

Question 2969Question →

Five minutes after a spontaneous vaginal delivery, while awaiting the expulsion of the placenta, the client suddenly grasps her chest and states, 'I can't breathe, and I feel like I'm going to die.' The client's skin rapidly becomes ashen and cyanotic. The bedside monitor reveals a sudden drop in oxygen saturation to 81% and a heart rate of 134 beats/min. Which sequence of immediate nursing actions is the highest priority?

Show answer & explanation

Answer: Administer oxygen at 10 L/min via a non-rebreather mask, establish secondary intravenous access, and prepare the crash cart for potential cardiopulmonary resuscitation.

Answer

The highest priority is to administer high-flow oxygen via a non-rebreather mask, establish additional intravenous access, and prepare for cardiopulmonary resuscitation.
The client is exhibiting the classic signs of Anaphylactoid Syndrome of Pregnancy (Amniotic Fluid Embolism), which is a rare but catastrophic obstetrical emergency characterized by sudden respiratory distress, cardiovascular collapse, and profound hypoxia. According to the ABCs (Airway, Breathing, Circulation) of prioritization, the nurse must immediately administer high-flow oxygen to treat the profound hypoxia, establish additional IV access for aggressive fluid resuscitation and medication administration, and prepare for imminent cardiopulmonary arrest.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
Sudden onset of severe dyspnea, cyanosis, hypoxia (SpO2 81%), tachycardia, and a feeling of impending doom immediately following delivery.
These are the classic hallmark signs of Anaphylactoid Syndrome of Pregnancy (Amniotic Fluid Embolism).
2
Apply the principles of prioritization (ABCs).
Airway and Breathing take immediate precedence over all other assessments and secondary interventions.
Without immediate oxygenation, the client will rapidly progress to cardiac arrest and anoxic brain injury.
3
Select the intervention sequence that directly addresses the physiological crisis.
Administering oxygen directly addresses hypoxia; establishing IV access and preparing the crash cart address the imminent risk of cardiovascular collapse.
This sequence targets the most lethal consequences of the embolism before addressing secondary complications like placental delivery or hemorrhage.

Question 2970Question →

An orthopedic unit nurse is updating the care plan for a geriatric client recovering from a right-sided posterior total hip arthroplasty. The client has developed unexpected episodes of nighttime restlessness and loss of bladder control. Which nursing actions are appropriate to ensure optimal hygiene, comfort, and safety? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Keep an abduction wedge secured between the client's lower extremities while they are lying flat in bed; Wash the perineal region promptly after voiding accidents and smooth on a protective zinc oxide paste

Answer

The appropriate actions are to keep an abduction wedge between the client's legs and to wash the perineal region promptly while applying a barrier paste.
The appropriate nursing actions address both the surgical restrictions and the basic care needs of the client. Maintaining an abduction wedge is a crucial standard of care following a posterior hip arthroplasty to prevent the leg from crossing the midline (adduction), which could dislocate the new joint. Additionally, for a client experiencing urinary incontinence, promptly washing the area and applying a zinc oxide paste is a fundamental intervention to protect the skin from moisture-associated damage and preserve tissue integrity.

Step-by-Step Solution

1
Analyze the client's surgical history (posterior total hip arthroplasty) to identify positioning restrictions.
Determine that the client must avoid hip flexion greater than 90 degrees, adduction, and internal rotation to prevent joint dislocation.
Post-operative anatomical safety dictates specific positional maintenance.
2
Evaluate the new-onset symptoms (urinary incontinence, nighttime restlessness) to determine basic care and safety needs.
Identify that incontinence requires prompt skin care to prevent breakdown, and acute restlessness requires assessment for underlying causes, not immediate restraints or dismissal as normal aging.
Maintaining physiological integrity and a safe care environment requires addressing acute changes appropriately.
3
Review the delegation principles regarding the unit technician (unlicensed assistive personnel).
Recognize that tasks requiring clinical assessment and evaluation cannot be delegated.
Ensuring safe and effective care requires appropriate scope of practice.

Key Concept

Basic care post-arthroplasty focuses on maintaining joint alignment to prevent dislocation, aggressively managing skin integrity during incontinence, and responding to acute cognitive changes clinically rather than punitively.

Question 2971Question →

A registered nurse is evaluating a nursing student's knowledge regarding the physiological adaptations of the respiratory system in older adults. The nurse asks the student to describe expected findings for an 83-year-old client who has no acute or chronic illness. Which statement by the student indicates an accurate understanding of normal senescence?

Show answer & explanation

Answer: The client has a diminished cough reflex and decreased ciliary function, which increases their vulnerability to respiratory infections.

Answer

The correct statement is that older adults experience a diminished cough reflex and decreased ciliary function, which increases their risk for respiratory infections.
As part of the normal aging process, the respiratory system undergoes progressive structural and functional declines. These expected physiological changes include a decreased number of functional cilia in the respiratory tract, a diminished and less effective cough reflex, and reduced respiratory muscle strength. Because these changes impair the airway's innate clearance mechanisms, older adults have a significantly higher susceptibility to respiratory infections, such as pneumonia.

Step-by-Step Solution

1
Analyze the question requirements
The question asks for the identification of expected, normal physiological changes in the respiratory system during the aging process (senescence).
Focusing on 'normal senescence' is crucial to avoid selecting pathological disease indicators.
2
Evaluate the option regarding tachypnea
Identify that a resting respiratory rate over 24 breaths per minute is abnormal.
Tachypnea at rest suggests an acute problem such as hypoxia, heart failure, or infection, rather than normal aging.
3
Evaluate the option regarding alveolar surface area
Identify that alveolar surface area decreases, not increases, with age.
Normal aging causes a loss of alveolar septa, leading to fewer but larger alveoli, which decreases the overall surface area for gas exchange.
4
Evaluate the option regarding chest diameter
Identify that a prominent barrel chest is a sign of pathology.
While a slight kyphosis can occur, a true barrel chest results from chronic hyperinflation associated with COPD.
5
Confirm the correct age-related respiratory change
Select the option stating that cough reflex and ciliary function diminish.
These are documented, normal physiological declines that compromise airway clearance in older adults.

Question 2972Question →

A nurse is preparing to administer a prescribed intravenous (IV) push medication through a client's peripheral saline lock. Place the following steps in the correct chronological order for safe administration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to assess the IV site, scrub the connector port, flush with saline to check patency, administer the medication, and flush with saline again to clear the line.
The correct sequence for administering an IV push medication through an intermittent device is known as the SAS method (Saline, Administer, Saline), preceded by critical safety and hygiene assessments. The nurse must first assess the site for complications. Next, the hub must be scrubbed for infection control. A pre-flush of normal saline follows to ensure the line is patent and ready. The medication is then administered at the correct rate. Finally, a post-flush of normal saline is administered at the same rate as the medication to clear the line and ensure the full dose is delivered.

Step-by-Step Solution

1
Assess the peripheral IV insertion site for any signs of complications.
The nurse confirms the IV site is free of redness, swelling, pain, or leakage.
Administering medication into a compromised or infiltrated IV site can cause severe tissue damage (extravasation) or fail to deliver the drug systemically.
2
Scrub the needleless connector port of the saline lock with an antimicrobial swab.
The entry point is disinfected.
Rigorous scrubbing of the hub prevents the introduction of microorganisms directly into the client's bloodstream.
3
Attach a syringe and flush the catheter with 0.9% sodium chloride to confirm patency.
The line flushes easily without resistance or patient discomfort.
This confirms the line is patent and clears any existing fluid that might be incompatible with the new medication.
4
Inject the prescribed medication at the recommended rate.
The medication is delivered safely into the bloodstream.
Therapeutic delivery of the drug requires adhering to safe push rates to avoid toxicity or speed shock.
5
Flush the catheter again with 0.9% sodium chloride at the same rate the medication was administered.
The medication is cleared from the tubing and the lock is maintained.
The final flush ensures the entire dose reaches the central circulation and prevents medication from lingering in the catheter, which could cause occlusion.

Question 2973Question →

A clinic nurse is utilizing the '5 R's' motivational intervention for a client who currently smokes but is not ready to quit. Arrange the nursing actions in the correct chronological sequence according to this evidence-based model.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence follows the '5 R's' model: determining Relevance, identifying Risks, recognizing Rewards, exploring Roadblocks, and utilizing Repetition.
The '5 R's' model is an evidence-based intervention designed to motivate clients who are unwilling to quit smoking at the current time. The correct sequence begins by establishing personal Relevance to build therapeutic rapport. Next, the nurse explores the Risks of continued smoking, followed immediately by the Rewards of quitting, which balances the negative and positive aspects of behavior change. The nurse then helps identify Roadblocks (barriers) to success. Finally, Repetition ensures the intervention is consistently applied during future interactions to capture any changes in the client's readiness.

Step-by-Step Solution

1
Determine Relevance
The nurse asks the client why quitting is personally relevant.
Establishing a personal connection and relevance is the foundation of motivational interviewing and must occur before discussing general risks.
2
Identify Risks
The nurse asks the client to list negative consequences of smoking.
Once personal relevance is established, the client is guided to articulate the negative impacts of their current lifestyle choice.
3
Recognize Rewards
The nurse asks the client to state the benefits of quitting.
Discussing rewards immediately after risks helps balance the conversation and emphasizes the positive aspects of behavior change.
4
Explore Roadblocks
The nurse helps the client identify barriers to quitting.
After establishing why the client should quit, the nurse must assess what practical or psychological barriers are standing in the way.
5
Utilize Repetition
The nurse repeats the motivational intervention.
Behavioral change takes time; repeating the intervention at each visit reinforces the message and continuously assesses for shifts in readiness.

Show answer & explanation

Answer

1. Stop the blood transfusion immediately. 2. Disconnect the blood tubing and initiate normal saline with new IV tubing. 3. Assess the client's vital signs and respiratory status. 4. Notify the healthcare provider and the blood bank.
The priority in any acute hemolytic transfusion reaction is to immediately stop the infusion of the incompatible blood product to minimize physiological harm. After stopping the transfusion, the nurse must maintain a patent intravenous line using normal saline and completely new tubing to ensure emergency medications can be given without pushing residual blood into the client. Once the source is removed and access is secured, the nurse performs a rapid assessment of vital signs and respiratory status to determine the severity of the reaction. Finally, the nurse notifies the healthcare provider to obtain treatment prescriptions and the blood bank to initiate a formal transfusion reaction investigation.

Step-by-Step Solution

1
Identify the clinical signs of an acute hemolytic transfusion reaction.
The client's lower back pain, chills, and shortness of breath indicate a life-threatening reaction.
Recognizing a severe reaction dictates immediate and prioritized nursing interventions.
2
Determine the most critical first action.
Stop the blood transfusion.
Preventing further exposure to the incompatible blood product is the highest priority to minimize harm.
3
Determine the next priority for maintaining vascular access.
Initiate normal saline with new tubing.
A patent IV line is required for emergency interventions, and new tubing prevents residual blood from entering the circulation.
4
Determine the next action for client safety.
Assess vital signs and respiratory status.
The nurse must gather current, objective hemodynamic and respiratory data to communicate to the provider.
5
Determine the final administrative and collaborative action.
Notify the healthcare provider and blood bank.
Medical orders are needed to treat the physiological response, and the blood bank must investigate the root cause of the reaction.

Question 2975Question →

A critical care nurse is removing a non-tunneled central venous catheter (CVC) from a client's right subclavian vein. Immediately after the catheter is withdrawn, the client gasps, reports sudden severe chest pain, and becomes pale and tachycardic. Suspecting a venous air embolism, arrange the following actions in the exact priority sequence the nurse must perform them to reduce the risk of fatal cardiopulmonary collapse.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first occlude the insertion site, position the client in the left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally prepare for cardiopulmonary resuscitation.
The physiological principle of managing a venous air embolism requires immediately stopping the source of the air leak, trapping the embolus to prevent pulmonary obstruction, treating the resulting hypoxemia, and then securing advanced medical help.

Step-by-Step Solution

1
Occlude the catheter insertion site immediately with a sterile, occlusive dressing.
Stops further air entry into the venous system.
Atmospheric pressure is higher than intrathoracic venous pressure during inspiration, drawing air in. Occlusion is the fastest way to stop the leak.
2
Reposition the client into the left lateral Trendelenburg position.
Traps the air embolus in the right side of the heart.
Durant's maneuver utilizes gravity to keep the buoyant air bubble in the right ventricular apex, preventing it from entering the pulmonary outflow tract.
3
Administer 100% high-flow oxygen via a non-rebreather face mask.
Treats hypoxemia and reduces the size of the air embolus.
High-concentration oxygen creates a diffusion gradient that accelerates the reabsorption of nitrogen (the primary component of room air) from the bubble.
4
Activate the hospital's emergency rapid response team.
Mobilizes advanced medical support.
The client requires immediate medical evaluation and potential advanced interventions such as right atrial aspiration or intubation.
5
Initiate continuous hemodynamic monitoring and prepare for cardiopulmonary resuscitation.
Ensures readiness for cardiac arrest.
Venous air embolism can rapidly evolve into obstructive shock and cardiopulmonary arrest, necessitating immediate advanced life support.

Question 2976Question →

A client in the trauma intensive care unit is receiving a massive transfusion protocol for severe hemorrhagic shock following a pelvic crush injury. After the rapid administration of 8 units of packed red blood cells and 6 units of fresh frozen plasma, the client's continuous electrocardiogram reveals a newly prolonged QT interval of 0.54 seconds. The nurse observes circumoral tingling and muscle fasciculations. Current vital signs include a heart rate of 112 beats per minute, blood pressure of 86/48 mm Hg, and a central venous pressure (CVP) of 9 mm Hg. Which of the following is the priority nursing action?

Show answer & explanation

Answer: Administer prescribed intravenous calcium gluconate

Answer

The correct action is to administer prescribed intravenous calcium gluconate.
The client is exhibiting clear signs of citrate toxicity, a known and dangerous complication of massive blood transfusions. Citrate, used as an anticoagulant in stored blood products, rapidly binds with the client's ionized calcium, precipitating severe hypocalcemia. This lack of ionized calcium manifests as neuromuscular irritability (circumoral tingling, fasciculations), a prolonged QT interval on the ECG, and decreased myocardial contractility (causing hypotension despite an adequate CVP of 9 mm Hg). The priority action is to immediately replace the ionized calcium by administering intravenous calcium gluconate or calcium chloride.

Step-by-Step Solution

1
Analyze the client's clinical presentation in the context of recent interventions.
The client received massive blood transfusions and is now exhibiting a prolonged QT interval, neuromuscular irritability, and hypotension.
To identify the underlying pathophysiological cause of the sudden deterioration.
2
Correlate the symptoms with potential complications of massive transfusion.
The symptoms are classic indicators of severe hypocalcemia caused by citrate toxicity.
Blood products contain citrate as an anticoagulant, which rapidly binds to the client's circulating ionized calcium.
3
Evaluate the hemodynamic parameters to determine the cause of hypotension.
The CVP is 9 mm Hg, indicating adequate right-sided filling pressures. The hypotension is therefore related to the negative inotropic effect of hypocalcemia, not hypovolemia.
To rule out unresolved hemorrhagic shock and prevent fluid overload.
4
Determine the most appropriate and immediate nursing intervention.
Administering intravenous calcium gluconate will directly correct the life-threatening ionized hypocalcemia.
Replacing ionized calcium restores myocardial contractility, resolves neuromuscular irritability, and shortens the dangerously prolonged QT interval.

A client with septic shock is receiving a continuous intravenous (IV) infusion of norepinephrine via a single-lumen peripherally inserted central catheter (PICC). The client's blood pressure is 88/54 mmHg88/54 \text{ mmHg} and the mean arterial pressure (MAP) is 65 mmHg65 \text{ mmHg}. The healthcare provider prescribes a stat dose of IV pantoprazole and a continuous IV infusion of regular insulin. The nurse is unable to establish additional peripheral IV access due to severe generalized edema. Which of the following actions should the nurse take? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Initiate the continuous regular insulin infusion by connecting it to the Y-site of the primary norepinephrine infusion tubing.; Contact the healthcare provider to urgently request the placement of a multi-lumen central venous catheter or intraosseous access.; Prioritize the continuous norepinephrine infusion and delay the IV pantoprazole administration until a secondary access line is obtained.

Answer

The correct actions are to initiate the insulin at the Y-site, request a multi-lumen catheter, and delay the pantoprazole until new access is obtained.
The correct actions prioritize the client's immediate survival (maintaining a MAP of 65 mmHg65 \text{ mmHg}) by never interrupting the norepinephrine infusion. Because regular insulin is compatible with norepinephrine, it can be safely connected to the Y-site. Because pantoprazole is highly incompatible with norepinephrine, it cannot be given through the same line. A new multi-lumen central line or intraosseous access must be requested, and the pantoprazole must be delayed until this safe access is established.

Step-by-Step Solution

1
Analyze the client's hemodynamic status.
The client is borderline stable with a MAP of 65 mmHg65 \text{ mmHg} solely dependent on a continuous norepinephrine infusion.
Determines the absolute priority of maintaining the vasopressor over all other interventions.
2
Determine medication compatibility for the prescribed drugs.
Regular insulin is compatible with norepinephrine, but pantoprazole is highly incompatible with norepinephrine.
Identifies which medications can be safely administered through the existing single-lumen PICC.
3
Formulate a safe administration plan.
The nurse can Y-site the insulin but must establish new access for the pantoprazole without interrupting the pressor.
Ensures timely medication administration while preventing life-threatening hypotension or IV line precipitation.

A multidisciplinary care team prescribes continuous total parenteral nutrition (TPN) alongside a separate 20%20\% intravenous lipid emulsion for a client recovering from an extensive bowel resection. The client currently has a single-lumen peripherally inserted central catheter (PICC). The primary TPN infusion set includes a standard 0.22-micron0.22\text{-micron} in-line filter. To safely administer both solutions concurrently, which action must the nurse implement?

Show answer & explanation

Answer: Attach the lipid emulsion infusion set to the primary TPN line at the port situated below the 0.22-micron0.22\text{-micron} filter.

Answer

The lipid emulsion must be connected to the primary TPN line at a port distal to (below) the 0.22-micron filter.
Total parenteral nutrition (TPN) solutions require a 0.22-micron filter to trap bacteria and particulate matter. However, intravenous lipid emulsions consist of large fat globules that cannot pass through this microscopic mesh. To administer both solutions concurrently through a single-lumen catheter, the lipid emulsion must be connected to the primary TPN line at a Y-port located below (distal to) the 0.22-micron filter. This technique successfully bypasses the filter for the lipids while ensuring the primary TPN solution remains properly filtered.

Step-by-Step Solution

1
Identify the physical and molecular properties of the prescribed intravenous solutions.
TPN contains dissolved small molecules (dextrose, amino acids) requiring a 0.22-micron filter to remove bacteria. Lipid emulsions contain large, emulsified fat globules.
Understanding molecular size dictates the specific filtration requirements for safe administration.
2
Determine the appropriate filtration mechanism for lipid emulsions.
Fat globules are significantly larger than 0.22 microns and cannot pass through this microscopic mesh without occluding it.
Forcing lipids through a standard micro-filter will halt the infusion, trigger pump occlusion alarms, and potentially rupture the filter membrane.
3
Select the correct anatomical point of connection on the primary IV tubing.
The lipid emulsion must bypass the 0.22-micron filter but still enter the client's single-lumen catheter concurrently with the continuous TPN.
Connecting the lipid tubing to the Y-port situated below (distal to) the 0.22-micron filter allows both solutions to mix safely just before entering the bloodstream, preserving the integrity of the filter.

Key Concept

When administering TPN and a lipid emulsion concurrently through a single-lumen central venous catheter, the lipid tubing must be connected below the 0.22-micron TPN filter to prevent complete occlusion of the filter membrane by large fat globules.

A community health nurse is preparing to conduct an initial health screening and risk assessment for a 45-year-old client who recently immigrated and has limited English proficiency. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence follows the nursing process: first, establish communication; second, collect subjective data; third, collect objective data; fourth, analyze the data to identify risks; and finally, implement targeted education.
The correct sequence for conducting a health screening strictly adheres to the nursing process (ADPIE) while prioritizing foundational communication. First, obtaining a medical interpreter ensures that the client is fully informed and can provide accurate information. Second, gathering subjective data allows the nurse to understand the client's background and specific concerns. Third, collecting objective data completes the comprehensive assessment phase. Fourth, analyzing the combined subjective and objective data enables the nurse to identify specific health risks (diagnosis). Finally, the nurse implements targeted interventions by providing culturally appropriate education based on those clearly identified risks.

Step-by-Step Solution

1
Obtain a professional medical interpreter to establish communication and explain the screening process.
Effective and legally appropriate communication is established.
A therapeutic relationship and informed consent are prerequisites for any assessment, requiring accurate communication as the immediate priority.
2
Elicit a comprehensive subjective health history, including past illnesses and immunization status.
Subjective baseline data is gathered.
The formal assessment phase begins with gathering subjective information directly from the client, which helps direct the focus of the physical examination.
3
Perform an objective physical assessment, including measuring vital signs and body mass index.
Objective baseline data is obtained.
Physical examination follows the health history to complete the comprehensive data collection phase.
4
Analyze the collected assessment data to identify specific risk factors for chronic and communicable diseases.
Client-specific health risks are diagnosed.
This step corresponds to the analysis phase of the nursing process, which must occur after all data is collected but before planning or implementing care.
5
Implement culturally appropriate client education regarding targeted primary and secondary disease prevention strategies.
Preventative strategies are initiated.
Implementation of client teaching must be tailored to the specific risks identified during the prior analysis phase.

A 78-year-old client residing in a skilled nursing facility suddenly develops acute confusion, agitation, and new-onset urinary incontinence. The nurse enters the client's room and observes the client attempting to climb over the bed rails. In what order should the nurse prioritize the following actions? (Arrange the actions from highest to lowest priority.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

1. Implement immediate safety measures
2. Obtain vital signs
3. Perform focused neurological assessment
4. Assess for potential localized triggers
5. Communicate findings to the provider
In older adults, acute changes such as confusion and incontinence often indicate an underlying pathology rather than normal aging. The nurse must prioritize care using the nursing process and safety frameworks. Immediate physical safety is the highest priority for an agitated client attempting to leave the bed. Following safety, assessing physiological stability (vital signs and oxygenation) is the next priority to rule out life-threatening causes of delirium like hypoxia. Once stable, a focused neurological assessment quantifies the acute change, followed by assessing for localized triggers (such as urinary issues). Finally, with all assessment data gathered, the nurse is fully prepared to notify the provider.

Step-by-Step Solution

1
Ensure immediate physical safety
The client is prevented from falling or sustaining injury.
When a client is acutely agitated and attempting an unsafe action, immediate physical safety intervention precedes all assessments.
2
Assess physiological stability via vital signs
Oxygenation and systemic hemodynamic status are evaluated.
Hypoxia or severe vital sign instability must be identified and corrected immediately, as they are primary physiological threats and common causes of delirium in older adults.
3
Conduct a focused neurological evaluation
The nurse determines the severity and nature of the cognitive change.
Understanding the specific neurological deficits helps confirm acute delirium versus an expected chronic cognitive baseline.
4
Investigate potential localized triggers
The nurse checks for common sources of infection or discomfort, such as the urinary tract.
Older adults frequently present atypically (e.g., sudden delirium and incontinence) when experiencing a UTI. Gathering this data is crucial before calling the provider.
5
Notify the healthcare provider
The provider is informed of the comprehensive assessment.
The nurse must have complete safety, vital sign, and assessment data ready before using SBAR to request diagnostic orders or medical treatments.
