Cevap

The correct sequence is: 1) Assess the mediastinal chest tubes for kinks, 2) Activate the rapid response team and notify the surgeon, 3) Administer a rapid intravenous crystalloid bolus, 4) Prepare for an immediate bedside echocardiogram, and 5) Gather the pericardiocentesis tray and prepare for sternotomy.
Cardiac tamponade post-CABG is a form of obstructive shock. The priority sequence reflects the nursing process and emergency prioritization: rapidly identify and reverse simple mechanical causes (kinked tubes), mobilize the emergency surgical team, support hemodynamics with increased preload (crystalloid fluids), assist with diagnostics (echocardiogram), and prepare for definitive surgical decompression.

Adım Adım Çözüm

1
Assess the mediastinal chest tubes for kinks or dependent loops.
Ensures there is no mechanical obstruction preventing pericardial drainage.
Resolving an obstruction is the quickest, least invasive way to reverse the accumulating fluid causing the tamponade. Independent nursing assessment of the equipment takes priority.
2
Activate the rapid response team and notify the cardiothoracic surgeon.
Mobilizes necessary medical personnel for an escalating emergency.
Cardiac tamponade is a lethal surgical complication requiring advanced interventions beyond the independent nursing scope of practice.
3
Administer a rapid intravenous crystalloid bolus as prescribed.
Increases right ventricular preload and systemic venous pressure.
Elevating filling pressures is hemodynamically essential to temporarily overcome the restrictive pericardial pressure and maintain cardiac output until the fluid can be drained.
4
Prepare the client for an immediate bedside echocardiogram.
Facilitates diagnostic confirmation of pericardial effusion.
The provider must visually confirm the presence and severity of the tamponade before proceeding with high-risk invasive procedures.
5
Gather the pericardiocentesis tray and prepare for a potential emergent sternotomy.
Readies the clinical environment for definitive treatment.
Evacuation of the pericardial fluid is the ultimate curative step, requiring sterile equipment and immediate surgical readiness.

Cevap

The priority intervention is to initiate a rapid bolus of the prescribed intravenous isotonic crystalloid solution.
The client is exhibiting signs of compensatory (early) hemorrhagic shock due to an upper gastrointestinal bleed. Although the systolic blood pressure remains >100>100 mm Hg, the narrowing pulse pressure (dropping from 5858 mm Hg to 2828 mm Hg), tachycardia, tachypnea, and restlessness are hallmark indicators of sympathetic nervous system activation in response to volume depletion. The immediate priority is to restore intravascular volume and cardiac output by administering isotonic crystalloid fluids.

Adım Adım Çözüm

1
Analyze the vital sign trends to identify physiological changes.
The pulse pressure has narrowed from 5858 mm Hg to 2828 mm Hg, accompanied by new-onset tachycardia (112112 bpm) and tachypnea (2424 breaths/min).
A narrowing pulse pressure is one of the earliest signs of compensatory shock, preceding a drop in systolic blood pressure.
2
Interpret the Arterial Blood Gas (ABG) values.
The ABG indicates uncompensated respiratory alkalosis (pH 7.497.49, PaCO 2_2 2929 mm Hg).
In early shock, sympathetic nervous system activation and tissue hypoxia trigger hyperventilation, blowing off carbon dioxide.
3
Evaluate the clinical symptoms in the context of the medical history.
The client with a suspected gastrointestinal bleed is exhibiting restlessness and lightheadedness.
These are early neurological indicators of decreased cerebral perfusion caused by hypovolemia.
4
Determine the highest priority nursing intervention.
Administering isotonic crystalloid fluids is selected as the first action.
Restoring intravascular volume is the critical first step in managing hemorrhagic shock and preventing cardiovascular collapse.

Cevap: Initiate a rapid intravenous infusion of 0.9% sodium chloride.

Cevap

Initiate a rapid intravenous infusion of 0.9% sodium chloride.
The correct intervention is to administer rapid isotonic fluids because the clinical picture indicates Cerebral Salt Wasting (CSW). CSW is a rare but life-threatening complication of subarachnoid hemorrhage characterized by primary renal sodium wasting, leading to severe hyponatremia and profound hypovolemia (evidenced by the low CVP, hypotension, and tachycardia). The immediate priority is restoring intravascular volume to prevent cerebral ischemia and multi-organ failure.

Adım Adım Çözüm

1
Analyze the vital signs and hemodynamic parameters.
The blood pressure of 82/46 mm Hg, heart rate of 126 beats/minute, and CVP of 1 mm Hg indicate profound hypovolemic shock.
Identifying the primary life-threat (circulatory collapse) dictates the immediate prioritization of care.
2
Evaluate the laboratory values and intake/output data.
The client has severe hyponatremia (119 mEq/L), low serum osmolality (256 mOsm/kg), inappropriate renal sodium wasting (urine sodium 120 mEq/L), and massive polyuria (1,600 mL/4 hours).
These specific values are required to differentiate between neuro-endocrine complications common after brain injury.
3
Synthesize the data to identify the underlying physiological adaptation failure.
The combination of severe hypovolemia, hyponatremia, and polyuria in a neurosurgical client confirms Cerebral Salt Wasting (CSW), eliminating SIADH (which is euvolemic/hypervolemic with oliguria) and Diabetes Insipidus (which causes hypernatremia).
Accurate pattern recognition prevents the administration of contraindicated therapies.
4
Determine the highest priority nursing intervention.
The nurse must immediately restore intravascular volume with an isotonic crystalloid solution like 0.9% sodium chloride.
Failure to rapidly correct the hypovolemia will lead to cerebral hypoperfusion, vasospasm, and irreversible brain damage.

Cevap: Assess the client's uterine fundus and current amount of lochia.

Cevap

The correct action is to immediately assess the client's uterine fundus and current amount of lochia.
The correct answer involves immediately assessing the client's uterine fundus and lochia. The client possesses multiple risk factors for postpartum hemorrhage, including multiparity, precipitous delivery, and uterine overdistention from a macrosomic newborn. The vital signs reveal a narrowed pulse pressure and tachycardia, accompanied by lightheadedness. These are classic early signs of hypovolemic shock secondary to blood loss. According to the nursing process, the priority is to directly assess the source of the suspected bleeding (uterine atony) to guide appropriate resuscitation and medical management.

Adım Adım Çözüm

1
Analyze the client's obstetric history for risk factors.
The client has a history of multiparity, precipitous delivery, and delivering a macrosomic newborn.
These three factors independently and synergistically increase the risk of uterine atony and subsequent postpartum hemorrhage.
2
Evaluate the current assessment findings and vital signs.
The client exhibits a narrowed pulse pressure (22 mmHg), tachycardia (114 beats/min), and lightheadedness.
These findings are early compensatory indicators of hypovolemic shock, suggesting significant concealed or overt blood loss.
3
Determine the priority intervention based on the nursing process.
The nurse must prioritize assessing the fundus and lochia.
Before initiating treatments for shock or delegating tasks, the registered nurse must assess the source of the suspected hemorrhage to guide targeted, life-saving interventions.

Cevabı ve açıklamayı göster

Cevap: Assign the client to a private room with negative pressure airflow.; Put on a fit-tested N95 respirator prior to entering the client's room.; Place a standard surgical mask on the client if transport to another department is required.

Cevap

The correct interventions are assigning the client to a private room with negative pressure airflow, putting on a fit-tested N95 respirator prior to entering, and placing a standard surgical mask on the client during transport.
Disseminated herpes zoster requires both Airborne and Contact precautions because the virus can be transmitted through respiratory aerosols and direct contact with blister fluid. An airborne infection isolation room (AIIR) with negative pressure airflow and a fit-tested N95 respirator are mandatory airborne precautions. Placing a standard surgical mask on the client during necessary transport provides essential source control to prevent transmission outside the isolation room.

Adım Adım Çözüm

1
Identify the pathogen and its mode of transmission.
Disseminated herpes zoster (shingles) is highly contagious and transmitted via airborne aerosols as well as direct contact with lesion fluid.
Understanding the specific transmission mechanisms dictates which tier of precautions must be implemented.
2
Determine the required transmission-based precautions.
Both Airborne and Contact precautions must be implemented concurrently until the lesions are dry and crusted.
Airborne precautions manage the respiratory/aerosol risk, while Contact precautions manage the risk of physical transmission from the vesicles.
3
Evaluate each provided intervention against Airborne and Contact precaution standards.
Negative pressure rooms, N95 respirators, and patient masking are correct Airborne measures. Delaying gown/glove use, opening the door, or allowing susceptible staff to enter violate the combined protocols.
Ensures all selected interventions strictly comply with evidence-based infection control guidelines.

Cevap: Assist the client to change position to a lateral recumbent or knee-chest posture.

Cevap

The priority nursing action is to assist the client to change position to a lateral recumbent or knee-chest posture.
The scenario describes variable decelerations, which are defined as visually apparent, abrupt decreases in the fetal heart rate that may or may not be associated with uterine contractions. This pattern is indicative of umbilical cord compression. The priority, first-line nursing intervention is to reposition the mother (e.g., side-lying, lateral recumbent, or knee-chest) to relieve the mechanical compression on the umbilical cord, thereby rapidly restoring uteroplacental blood flow and fetal oxygenation.

Adım Adım Çözüm

1
Analyze the fetal heart rate monitor tracing described in the scenario.
The pattern shows abrupt decreases in heart rate that are independent of uterine contractions.
Identifying the specific type of deceleration is required to determine the underlying physiological cause.
2
Correlate the fetal heart rate pattern with its physiological cause.
Abrupt, variable decreases (variable decelerations) indicate umbilical cord compression.
Using frameworks like the VEAL CHOP mnemonic helps link the pattern to the specific physiological problem.
3
Determine the highest priority nursing intervention to resolve the specific problem.
The immediate action is to reposition the client to relieve mechanical pressure on the umbilical cord.

A nurse is planning care for a client who is 48 hours post-operative following a right above-the-knee amputation (AKA) due to complications of peripheral arterial disease. Which of the following positioning interventions is most appropriate to include in the client's plan of care?

Cevabı ve açıklamayı göster

Cevap: Assist the client into a prone position for 30 minutes three to four times a day.

Cevap

Assist the client into a prone position for 30 minutes three to four times a day.
Following an above-the-knee amputation, the client is at high risk for developing a hip flexion contracture, which can permanently impair mobility and the ability to bear weight on a prosthesis. Assisting the client into a prone position for 20 to 30 minutes, 3 to 4 times a day, actively extends the hip joint and stretches the flexor muscles, effectively preventing contractures.

Adım Adım Çözüm

1
Analyze the client's surgical procedure and timeline.
The client had a right above-the-knee amputation (AKA) 48 hours ago.
The timeline is critical because therapeutic positioning rules change drastically after the first 24 hours post-operation.
2
Identify the primary positioning complication associated with an AKA.
Hip flexion contracture is a severe structural complication that can prevent the client from using a prosthesis.
Understanding the complication risk guides the selection of appropriate preventative positioning.
3
Evaluate the given options based on their effect on the hip joint.
Elevation and high Fowler's position promote hip flexion. Prone positioning actively promotes hip extension.
Nursing interventions must counter the physiological tendency of the hip flexor muscles to tighten and contract.

While attending an off-duty community event at a large indoor stadium, a structural collapse occurs, resulting in mass casualties. A nurse establishes a preliminary triage area for the victims. Based on the START (Simple Triage and Rapid Treatment) algorithm, which individual should the nurse classify as an immediate priority?

Cevabı ve açıklamayı göster

Cevap: An individual with a head contusion who has a respiratory rate of 26 breaths/min, a palpable radial pulse, but is unable to follow the command to open their eyes.

Cevap

The individual with a head contusion who has a respiratory rate of 26 breaths/min, a palpable radial pulse, but is unable to follow the command to open their eyes.
The correct answer identifies a client who fails the mental status component of the START (Simple Triage and Rapid Treatment) algorithm. After confirming the client is not ambulatory, the nurse assesses Respirations (RR < 30 is stable), Perfusion (palpable radial pulse is stable), and Mental Status. Because the client cannot follow simple commands, they require an immediate priority classification (red tag).

Adım Adım Çözüm

1
Assess ambulatory status.
The individual who is walking around the scene is categorized as 'Green' (minor/minimal priority).
Ambulatory clients are directed away from the immediate scene to clear space and are considered the walking wounded.
2
Assess the respiratory effort of the remaining non-ambulatory victims.
The apneic victim remains without respirations after airway positioning and is tagged 'Black' (expectant). The other two victims have respiratory rates under 30 breaths/min.
Victims who do not breathe after airway maneuvers are deceased or expectant; resources cannot be expended on them during a mass casualty event. Respiratory rates over 30 require a 'Red' tag.
3
Assess perfusion in the victims breathing less than 30 times per minute.
Both remaining victims have adequate perfusion (capillary refill < 2 seconds or a palpable radial pulse).
Inadequate perfusion (capillary refill > 2 seconds or absent radial pulse) would require immediate hemorrhage control and a 'Red' tag.
4
Assess mental status in victims with adequate respirations and perfusion.
The victim with the femur fracture is alert (screaming/vocalizing) and receives a 'Yellow' tag. The victim with the head contusion cannot follow simple commands and receives a 'Red' tag.
An inability to follow simple commands indicates a significant neurological compromise or inadequate cerebral perfusion, categorizing the client as an immediate life threat requiring a 'Red' tag.

A nurse is caring for a client who is receiving continuous enteral tube feedings and requires repositioning every 2 hours to prevent pressure injuries. Which of the following actions is the most appropriate for the nurse to take when turning the client?

Cevabı ve açıklamayı göster

Cevap: Pause the continuous enteral feeding before lowering the head of the bed.

Cevap

Pause the continuous enteral feeding before lowering the head of the bed.
Pausing the enteral feeding before lowering the head of the bed is essential to prevent pulmonary aspiration of gastric contents. Repositioning requires the bed to be lowered to minimize shearing forces on the client's skin and to maintain proper body mechanics for the staff. However, because enteral feeding must always be stopped when the head of the bed is lower than 30 degrees, pausing the pump is the necessary first step.

Adım Adım Çözüm

1
Identify the primary physiological risk for a client receiving continuous enteral feedings.
The highest risk is pulmonary aspiration of gastric contents if the head of the bed is lowered.
Enteral nutrition introduces liquid directly into the stomach, increasing the volume of gastric contents and the potential for reflux.
2
Determine the proper mechanics for safely turning a client in bed.
The head of the bed should be lowered to flat or nearly flat before turning.
Turning a client with the head of the bed elevated creates severe shearing forces on the sacrum, which causes pressure injuries and makes turning ergonomically difficult for the nurse.
3
Combine the safety requirements of both interventions (feeding and turning).
The feeding must be temporarily stopped so the head of the bed can be safely lowered for turning.
This dual approach prevents aspiration while also adhering to safe mobility and skin integrity practices.

While evaluating the labor progress of a gravida 2, para 1 client receiving oxytocin augmentation, the nurse identifies a gradual, symmetric decrease in the fetal heart rate that begins consistently after the peak of successive contractions. The heart rate returns to baseline only after the contraction has fully resolved. Which intervention is the most appropriate initial action?

Cevabı ve açıklamayı göster

Cevap: Stop the intravenous oxytocin administration.

Cevap

The correct action is to stop the intravenous oxytocin administration to improve uteroplacental perfusion.
The fetal heart rate pattern described indicates late decelerations, which are a sign of uteroplacental insufficiency. When a client is receiving an oxytocin infusion, the medication forces the uterus to contract, which further decreases blood flow to the placenta. Therefore, the absolute first priority is to stop the oxytocin infusion to decrease uterine activity, thereby improving blood flow and oxygenation to the compromised fetus.

Adım Adım Çözüm

1
Analyze the described fetal heart rate (FHR) pattern.
The gradual decrease starting after the contraction peak and recovering after the contraction ends defines a late deceleration.
Accurate interpretation of electronic fetal monitoring is essential to distinguish between benign and pathological patterns.
2
Determine the physiological cause of the identified pattern.
Late decelerations are caused by uteroplacental insufficiency, meaning the fetus is not receiving adequate oxygen during contractions.
Understanding the cause dictates the appropriate clinical intervention.
3
Prioritize the necessary nursing interventions for intrauterine resuscitation.
The immediate priority is to maximize fetal oxygenation by removing stressors (stopping oxytocin), repositioning the mother, and administering oxygen.
According to the ABCs and prioritization principles, direct actions that restore physiological stability take precedence over documentation or provider notification.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for donning PPE is: 1) Perform hand hygiene, 2) Don isolation gown, 3) Place N95 respirator, 4) Apply face shield or goggles, 5) Put on clean gloves.
According to CDC guidelines, the standard sequence for donning PPE begins with hand hygiene to prevent contaminating the clean PPE. Next, the isolation gown is applied to cover the body. The N95 respirator is placed next to ensure a proper seal against the face, followed by eye protection (goggles or face shield). Finally, gloves are donned last so they can securely cover the cuffs of the gown, completing the barrier.

Adım Adım Çözüm

1
Identify the appropriate transmission-based precautions for disseminated varicella-zoster virus.
Determine that Airborne and Contact precautions, plus standard precautions, are required.
Disseminated varicella spreads through both aerosolized airborne particles and direct contact with lesions.
2
Select the first action in the standard CDC PPE donning sequence.
Identify hand hygiene as the starting step.
Hands must be clean before touching clean PPE to prevent transmission of pathogens onto the equipment.
3
Select the first piece of physical PPE to don.
Identify the isolation gown.
The gown covers the torso and arms, providing the largest area of protection, and is secured at the neck and waist before applying facial gear.
4
Determine the correct order for facial protection.
Place the N95 respirator first, followed by the face shield or goggles.
The N95 respirator must be applied directly to the face to ensure an adequate seal; eye protection is then placed over the top.
5
Identify the final step in the sequence.
Put on clean gloves.
Gloves are placed last so they can be pulled up and over the cuffs of the isolation gown, closing any gaps at the wrists.

A specialized medical task force arrives at the site of a severe passenger train derailment. As part of the initial disaster response team utilizing the Simple Triage and Rapid Treatment (START) algorithm, which casualty should the nurse categorize as requiring immediate, life-saving intervention?

Cevabı ve açıklamayı göster

Cevap: A casualty with a large abdominal laceration who is breathing 22 times per minute, obeys commands, and has an absent radial pulse.

Cevap

The casualty with the abdominal laceration and an absent radial pulse should be categorized for immediate intervention.
The casualty with an absent radial pulse requires an Immediate (Red) tag. The START algorithm prioritizes casualties based on Respiration, Perfusion, and Mental Status (RPM). Although this casualty is breathing normally and obeys commands, the absent radial pulse indicates severe circulatory compromise and shock, meaning they require immediate life-saving intervention.

Adım Adım Çözüm

1
Assess for casualties who are able to walk away from the incident.
The casualty with the deformed wrist can walk and is categorized as Minimal (Green tag).
Separating the 'walking wounded' immediately reduces the number of casualties requiring complex triage in the hot zone.
2
Evaluate the respiratory status of the remaining non-ambulatory casualties.
The casualty trapped under debris remains apneic after airway repositioning and is categorized as Expectant (Black tag).
In a mass casualty incident, extensive resources like CPR are not initiated for apneic clients in order to ensure the most good is done for the greatest number of people.
3
Assess the circulation and perfusion of the casualties who are breathing effectively.
The casualty with the abdominal laceration has an absent radial pulse, meeting criteria for Immediate (Red tag).
An absent radial pulse indicates severe systemic shock and hemodynamic instability, taking precedence over their stable respiratory rate.
4
Evaluate the mental status of casualties with intact airway, breathing, and circulation.
The casualty with the suspected spinal cord injury has stable vitals and obeys commands, making them Delayed (Yellow tag).
Although the mechanism of injury is severe, the casualty is physiologically stable enough to wait for transport while life-threatening injuries in others are addressed.

A nurse is assisting with the delivery of a newborn. Immediately after birth, the newborn is apneic and limp. Arrange the following neonatal resuscitation interventions in the correct chronological sequence according to standard clinical guidelines.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first warm, dry, and stimulate the newborn; then evaluate the respiratory effort and heart rate; next, initiate positive-pressure ventilation if needed; followed by chest compressions if the heart rate remains critically low; and finally, administer epinephrine if all previous steps fail.
The Neonatal Resuscitation Program (NRP) algorithm dictates a step-wise approach based on the newborn's response. The foundational steps are to provide warmth, dry, and stimulate. This is immediately followed by an evaluation of heart rate and breathing. If the infant is apneic or the heart rate is less than 100 beats/min, positive-pressure ventilation (PPV) is the critical next intervention. If the heart rate falls below 60 beats/min despite effective PPV, chest compressions are initiated. Finally, if the heart rate remains below 60 beats/min despite PPV and compressions, epinephrine is administered.

Adım Adım Çözüm

1
Perform initial steps of resuscitation.
The newborn is placed on a radiant warmer, dried, and stimulated.
These actions prevent cold stress, clear the airway, and encourage spontaneous respirations.
2
Assess the newborn's physiological status.
Respiratory effort and heart rate are evaluated.
Assessment determines the need for advanced resuscitation measures based on the standard algorithm.
3
Provide ventilatory support.
Positive-pressure ventilation (PPV) is initiated.
PPV is required if the newborn remains apneic, is gasping, or has a heart rate less than 100 beats/min.
4
Perform circulatory support.
Chest compressions are started.
Compressions are indicated if the heart rate remains less than 60 beats/min despite effective PPV.
5
Administer emergency medications.
Epinephrine is administered.
Medication is used as a last resort when the heart rate remains less than 60 beats/min despite PPV and compressions.

A nurse is caring for a client who just underwent a percutaneous liver biopsy and is now prescribed a packed red blood cell (PRBC) transfusion for acute blood loss. Which interventions are essential for the nurse to implement to prevent accidents, errors, and injury? Select all that apply.

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Verify the client's identity, blood type, and the PRBC unit with a second registered nurse at the bedside.; Ensure the blood product is administered through a dedicated IV line primed only with 0.9% sodium chloride.; Position the client on their right side with a rolled towel placed under the biopsy site.

Cevap

The correct actions are to verify the client and blood product with a second registered nurse, ensure the use of a dedicated IV line with 0.9% sodium chloride, and position the client on their right side with a towel under the biopsy site.
Preventing injury after a liver biopsy requires positioning the client on their right side to apply direct pressure to the liver capsule, minimizing the risk of hemorrhage. Safe administration of blood products requires dual verification by two registered nurses at the bedside to prevent fatal ABO incompatibility errors. Additionally, blood products must only be infused with 0.9% sodium chloride to prevent hemolysis of the red blood cells in the IV tubing.

Adım Adım Çözüm

1
Evaluate the safety and infection control requirements for blood administration.
Identify the need for dual registered nurse verification and a dedicated line primed only with normal saline.
Strict protocol adherence prevents life-threatening ABO incompatibility and hemolysis of the transfused cells.
2
Determine the optimal post-procedural safety positioning for a liver biopsy.
Select right-side positioning with direct pressure applied to the area.
The liver is a highly vascular organ; applying direct pressure to the biopsy site is critical to prevent internal hemorrhage.
3
Assess the appropriateness of task delegation during the high-risk initiation of a transfusion.
Recognize that the registered nurse must personally conduct the continuous 15-minute monitoring.
Monitoring for subtle, early signs of an adverse transfusion reaction requires independent clinical judgment that cannot be delegated to a UAP.
