A nurse is caring for a client who recently received an intravenous dose of morphine for severe postoperative pain. During the reassessment, the nurse notes that the client is difficult to arouse, has pinpoint pupils, and has a respiratory rate of 8 breaths per minute. Which of the following actions should the nurse take first?

Cevabı ve açıklamayı göster

Cevap: Prepare to administer the prescribed naloxone.

Cevap

The priority action is to prepare to administer the prescribed naloxone to reverse the opioid toxicity.
The client is exhibiting the classic triad of opioid toxicity: respiratory depression, pinpoint pupils, and altered level of consciousness. A respiratory rate of 8 breaths per minute is dangerously low and compromises the client's breathing. According to the ABCs (Airway, Breathing, Circulation) framework, addressing this respiratory failure is the immediate priority. Naloxone is the specific opioid antagonist that quickly reverses these life-threatening effects.

Adım Adım Çözüm

1
Assess the client's clinical presentation.
The client has a respiratory rate of 8 breaths per minute, pinpoint pupils, and altered mental status.
Identifying these findings confirms the classic triad of opioid toxicity.
2
Apply a prioritization framework.
Using the ABCs (Airway, Breathing, Circulation), the severe respiratory depression is identified as the most critical and immediate threat to the client's life.
Life-threatening physiological needs must be addressed before secondary assessments or interventions.
3
Determine the appropriate pharmacological intervention.
Naloxone is identified as the required antidote.
Naloxone displaces opioids from receptor sites, rapidly reversing respiratory depression.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: elevate the head of the bed, check the gastric residual volume, flush the tube, administer the feeding formula, and finally flush the tube again.
Safe administration of enteral feeding requires a logical progression prioritizing client safety. Positioning the client upright comes first to prevent aspiration. Next, measuring residual volume confirms gastrointestinal tolerance. An initial flush verifies tube patency, followed by the actual formula administration. Finally, a post-feeding flush clears the tube to maintain future patency.

Adım Adım Çözüm

1
Elevate the head of the bed to 30 to 45 degrees.
The client is placed in a semi-Fowler's position.
This is the most important initial safety step to prevent aspiration of stomach contents into the lungs.
2
Check the gastric residual volume.
The amount of undigested formula left in the stomach is measured.
This step determines if the client is tolerating the feedings and prevents overfilling the stomach.
3
Flush the tube with 30 mL of water.
The tube is cleared and confirmed to be patent.
Checking patency before administering the formula ensures the feeding will flow smoothly without blockages.
4
Administer the prescribed enteral feeding formula.
The client receives their prescribed nutrition.
Nutrition can be safely delivered once all safety and patency checks are complete.
5
Flush the tube again with 30 mL of water.
The tube is cleared of all formula residue.
Formula left in the tube can dry, cause occlusions, and serve as a medium for bacterial growth.

An older adult client is admitted to the medical-surgical floor with severe bilateral lower extremity edema associated with chronic venous insufficiency. What is the most appropriate action by the nurse to manage the client's swelling and promote comfort?

Cevabı ve açıklamayı göster

Cevap: Elevate the client's legs above the level of the heart while resting

Cevap

The most appropriate action is to elevate the client's legs above the level of the heart while resting.
Elevating the lower extremities above the level of the heart is a fundamental nursing intervention for chronic venous insufficiency. Gravity assists the compromised venous valves in returning blood and interstitial fluid back to the central circulation, thereby decreasing hydrostatic pressure in the legs, reducing edema, and improving client comfort.

Adım Adım Çözüm

1
Assess the pathophysiology of the client's discomfort
The client has bilateral lower extremity edema due to chronic venous insufficiency, which causes fluid to pool in the legs.
Understanding the cause of the edema directs the appropriate positioning intervention.
2
Determine the optimal positioning to counteract fluid pooling
Elevation of the extremities above the heart is selected as the primary intervention.
Gravity facilitates the return of venous blood and lymphatic fluid back to the central circulation, effectively reducing peripheral swelling.
3
Ensure the chosen intervention avoids safety hazards
Avoid placing pressure behind the knees (popliteal space) and avoid massaging the calves.
Popliteal pressure impedes blood flow, and calf massage can dislodge a deep vein thrombosis.

A registered nurse is caring for a client at 38 weeks gestation in active labor. Fifteen minutes ago, the client received a continuous lumbar epidural infusion for pain management. The nurse assesses the client and notes that her blood pressure has decreased from 124/78 mmHg to 92/54 mmHg. Simultaneously, the external fetal monitor displays recurrent, gradual decreases in the fetal heart rate (FHR) that begin after the peak of the uterine contractions and return to the baseline only after the contractions have ended.

Which of the following actions should the nurse perform first?

Cevabı ve açıklamayı göster

Cevap: Assist the client into a lateral recumbent position and increase the rate of the primary intravenous fluid infusion.

Cevap

Assist the client into a lateral recumbent position and increase the rate of the primary intravenous fluid infusion.
The correct response addresses the direct cause of the fetal distress. The client is experiencing epidural-induced hypotension, which reduces uteroplacental perfusion, leading to fetal hypoxia (manifested as late decelerations). The immediate nursing priority is to independently restore circulating maternal volume and blood flow to the uterus. Placing the client in a lateral recumbent position relieves aortocaval compression, and increasing the intravenous fluid rate expands intravascular volume. Both actions work synergistically to quickly improve maternal blood pressure and fetal oxygenation.

Adım Adım Çözüm

1
Analyze the maternal vital signs.
The maternal blood pressure has significantly decreased following the epidural administration, indicating epidural-induced sympathetic blockade and vasodilation.
Epidural analgesia commonly blocks sympathetic vasomotor nerves, leading to peripheral blood pooling and decreased venous return to the heart.
2
Interpret the fetal heart rate (FHR) tracing.
The FHR shows recurrent, gradual decreases where the nadir occurs after the contraction peak, which are clinically defined as late decelerations.
Late decelerations signify uteroplacental insufficiency. In this scenario, they are secondary to the maternal hypotension physically reducing oxygenated blood flow to the placenta.
3
Prioritize nursing interventions based on ABCs and independent nursing scope.
The nurse must immediately implement independent mechanical actions to restore maternal circulating volume before utilizing dependent pharmacological orders or delegating tasks.
Repositioning the client laterally relieves aortocaval compression from the gravid uterus, and increasing IV fluids expands intravascular volume. Together, these actions represent the fastest, most effective first-line treatment to correct maternal hemodynamics and restore fetal oxygenation.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first determine unresponsiveness and call for help, then check the pulse and breathing, initiate ventilations to correct hypoxia, administer naloxone to reverse the overdose, and finally monitor for recurrent respiratory depression.
According to basic life support and emergency guidelines for a suspected opioid overdose, the absolute first priority is to assess responsiveness and call for help to activate the emergency response system. Next, the nurse must simultaneously check for a pulse and breathing. Upon identifying severe respiratory depression (6 breaths per minute) with a likely pulse, the immediate physiological need is oxygenation; therefore, the nurse must open the airway and provide ventilations. Once breathing is mechanically supported, the nurse administers naloxone to reverse the opioid effects. Finally, continuous reassessment is critical because the half-life of naloxone is often shorter than the opioid ingested, putting the client at high risk for a recurrence of respiratory depression.

Adım Adım Çözüm

1
Determine unresponsiveness and call for immediate help.
Activates the emergency response team.
Ensures adequate personnel and equipment (such as a crash cart) are en route before beginning physical interventions.
2
Simultaneously check the carotid pulse and observe for breathing.
Identifies whether the client requires full CPR or solely respiratory support.
Guides the appropriate progression of the basic life support algorithm based on circulatory status.
3
Open the airway and initiate bag-valve-mask ventilations.
Provides immediate oxygenation to the client.
Reversing severe hypoxia is the primary physiological priority. Interventions for oxygenation must not be delayed.
4
Administer the prescribed dose of intravenous naloxone.
Reverses the opioid-induced central nervous system and respiratory depression.
Treats the underlying toxicological cause of the respiratory failure once the airway is supported.
5
Reassess the client continuously for recurrent respiratory depression.
Monitors the sustained effectiveness of the reversal agent.
Naloxone has a shorter half-life than many opioids, meaning the client could slip back into a comatose, apneic state.

A client with acute decompensated heart failure is receiving continuous intravenous (IV) infusions of milrinone at 0.5 mcg/kg/min0.5 \text{ mcg/kg/min} and heparin at 1,200 units/hr1,200 \text{ units/hr} through a double-lumen central venous catheter (CVC). The client's morning serum potassium level is 2.6 mEq/L2.6 \text{ mEq/L}. The healthcare provider prescribes a single dose of potassium chloride (KCl) 40 mEq40 \text{ mEq} in 100 mL100 \text{ mL} of 0.9%0.9\% sodium chloride to infuse intravenously over 4 hours4 \text{ hours}. The nurse consults a parenteral drug reference and notes that KCl is physically incompatible with both milrinone and heparin at the Y-site. Which action is the most appropriate for the nurse to take?

Cevabı ve açıklamayı göster

Cevap: Contact the healthcare provider to discuss alternative central venous access or an enteral route, as the prescribed KCl concentration is unsafe for peripheral administration.

Cevap

Contact the healthcare provider to discuss alternative central venous access or an enteral route, as the prescribed KCl concentration is unsafe for peripheral administration.
The prescribed KCl concentration (40 mEq40 \text{ mEq} in 100 mL100 \text{ mL}, or 0.4 mEq/mL0.4 \text{ mEq/mL}) significantly exceeds the maximum safe concentration for peripheral IV administration, which is typically 10 mEq10 \text{ mEq} per 100 mL100 \text{ mL} (0.1 mEq/mL0.1 \text{ mEq/mL}). Administering this concentration peripherally poses a severe risk of phlebitis and tissue necrosis. Because the existing central line is fully occupied by critical, continuous infusions (milrinone for cardiac output and heparin for anticoagulation) that are incompatible with KCl and cannot be safely paused, the nurse is unable to safely administer the medication as ordered. The only safe action is to contact the provider to establish new central access, dilute the medication further (if fluid status permits), or change to an enteral route.

Adım Adım Çözüm

1
Analyze the prescribed KCl concentration and determine safe administration routes.
The concentration is 40 mEq40 \text{ mEq} in 100 mL100 \text{ mL} (0.4 mEq/mL0.4 \text{ mEq/mL}). This exceeds the maximum peripheral limit (0.1 mEq/mL0.1 \text{ mEq/mL}) and absolutely requires central venous administration.
High concentrations of potassium chloride are hyperosmolar and highly irritating, causing severe chemical phlebitis if given via a peripheral vein.
2
Assess the availability of the current central venous access.
Both lumens of the CVC are occupied by milrinone (a critical inotrope for heart failure) and heparin (a critical anticoagulant).
Incompatible medications cannot share the same IV lumen due to the risk of precipitate formation and drug inactivation.
3
Evaluate if the continuous infusions can be safely interrupted.
Neither infusion can be paused. Milrinone is life-sustaining for cardiac output, and pausing heparin for 4 hours4 \text{ hours} (well past its 1-2 hour half-life) risks severe thrombosis.
Nursing prioritization requires maintaining hemodynamic and hematologic stability; critical continuous drips should never be paused for routine electrolyte replacement.
4
Determine the necessary nursing intervention.
The nurse must withhold the medication and contact the healthcare provider to request a safe alternative.
Safe administration requires either placing a new central line, ordering a larger volume dilution safe for a new peripheral IV (if fluid restriction allows), or utilizing the enteral route.

Cevap: Suspending the enteral infusion before lowering the head of the bed to provide perineal hygiene and relieve sacral pressure

Cevap

The nurse must suspend the enteral infusion before lowering the head of the bed to provide perineal hygiene and relieve sacral pressure.
Suspending the enteral feeding before lowering the head of the bed is the correct priority action. It is essential to prevent regurgitation and pulmonary aspiration during repositioning and hygiene care. Maintaining an elevated head of bed is a mandatory safety parameter for active enteral infusions.

Adım Adım Çözüm

1
Analyze the client's current clinical situation and risk factors.
The client is receiving continuous PEG feedings, has sacral erythema requiring offloading and frequent hygiene, and exhibits sudden cognitive changes.
Identifying overlapping needs (skin integrity vs. aspiration risk) is required to prioritize safe care delivery.
2
Evaluate the safety parameters for positioning a client receiving continuous enteral nutrition.
The head of the bed must be elevated at 30 to 45 degrees during active feeding to utilize gravity in preventing reflux.
A flat position during feeding severely increases the risk of gastric contents entering the respiratory tract.
3
Determine the appropriate intervention that addresses skin integrity without compromising airway safety.
The feeding pump must be paused prior to repositioning the client flat for hygiene and pressure relief.
This sequenced approach balances the need for essential incontinence care with critical airway protection.

The proper sequence is: don personal protective equipment, gently roll the soiled linens away from the body, place them in a leak-proof biohazard bag, remove the protective equipment, and finally wash hands with soap and water.
Handling infectious linens requires a strict sequential protocol to maintain environmental safety and prevent cross-contamination. The nurse must first protect themselves by donning appropriate personal protective equipment (PPE). Next, the linens must be handled gently and rolled away from the body to prevent aerosolizing spores. The contaminated linens are immediately secured in a leak-proof biohazard laundry bag to contain the infectious material. Finally, the nurse removes their contaminated PPE and performs hand hygiene specifically with soap and water, because alcohol-based sanitizers do not eradicate C. difficile spores.

Adım Adım Çözüm

1
Don a fluid-resistant isolation gown and clean gloves.
The nurse is protected from exposure to infectious bodily fluids.
Personal protective equipment must be donned prior to contact with the contaminated environment.
2
Roll the soiled linens carefully away from the body without shaking them.
The contaminated surface is folded inward, containing the infectious material.
This minimizes the aerosolization of spores and prevents the soiled linens from touching the nurse's uniform.
3
Place the rolled linens directly into a designated leak-proof biohazard laundry bag.
The infectious material is secured and contained.
Immediate containment in a designated bag prevents environmental contamination and protects laundry handling staff.
4
Remove and discard the gown and gloves into the appropriate infectious waste receptacle.
Contaminated protective gear is safely disposed of.
Doffing equipment inside the patient's room prevents the spread of pathogens outside the isolation area.
5
Perform hand hygiene by washing hands thoroughly with soap and water.
Hands are mechanically cleansed of pathogens.
Soap and water must be used because alcohol-based hand sanitizers cannot kill Clostridioides difficile spores.

Cevabı ve açıklamayı göster

Cevap: Position an abduction pillow between the client's lower extremities.; Maintain the affected right extremity in neutral alignment.; Ensure the use of an elevated toilet seat for elimination needs.

Cevap

The correct interventions are positioning an abduction pillow between the legs, maintaining the affected extremity in neutral alignment, and using an elevated toilet seat.
Following a posterolateral total hip arthroplasty, the primary risk reduction strategy involves preventing dislocation of the newly placed joint. This requires strict adherence to hip precautions: avoiding adduction, internal rotation, and hip flexion greater than 90 degrees. Using an abduction wedge actively prevents adduction, keeping the leg in neutral alignment prevents internal rotation, and utilizing a raised toilet seat effectively prevents excessive hip flexion when sitting.

Adım Adım Çözüm

1
Identify the surgical procedure and approach.
Right total hip arthroplasty using a posterolateral approach.
The surgical approach determines which specific postoperative movements are contraindicated to prevent joint dislocation.
2
Determine the contraindicated movements for a posterolateral approach.
Avoid hip adduction, internal rotation, and hip flexion greater than 90 degrees.
These specific positions and movements put excessive pressure on the posterior joint capsule, potentially forcing the new femoral head out of the socket.
3
Evaluate each nursing intervention against the contraindications.
Select the interventions that promote abduction, maintain neutral alignment, and prevent excessive hip flexion.
Choosing these actions directly reduces the risk of the severe physiological complication of joint dislocation.

Which of the following is the most appropriate response by the nurse?

Cevabı ve açıklamayı göster

Cevap: Pre-exposure prophylaxis significantly reduces your risk for HIV, but it offers no protection against other sexually transmitted infections.

Cevap

The most appropriate response is to inform the client that while PrEP significantly reduces the risk of HIV, it offers no protection against other sexually transmitted infections.
The correct answer directly addresses the client's knowledge deficit using a factual, non-judgmental approach. Pre-exposure prophylaxis (PrEP) is highly effective at preventing the transmission of HIV, but it does not provide a barrier against other sexually transmitted infections (STIs). Therefore, the nurse must provide accurate harm-reduction education by emphasizing that barrier methods are still necessary.

Adım Adım Çözüm

1
Analyze the client's statement.
The client mistakenly believes that taking PrEP eliminates the need for condom use during sexual encounters.
Identifying the specific knowledge deficit is the first step in providing targeted harm-reduction education.
2
Evaluate the clinical facts regarding PrEP.
PrEP is highly effective at preventing HIV infection but provides no physical barrier against bacterial or viral sexually transmitted infections (STIs) such as syphilis, gonorrhea, or chlamydia.
Understanding the pharmacological and physical limitations of the treatment forms the basis for the necessary nursing intervention.
3
Select the most therapeutic and accurate response.
The nurse must provide factual, non-judgmental education that directly corrects the client's misconception.

The nurse observes the client lying in the left lateral decubitus position with the head of the bed elevated 30 degrees. Assessment reveals absent breath sounds on the right side and a trachea that is deviated slightly to the right. Which intervention should the nurse implement FIRST to reduce the client's risk for sudden physiological decompensation?

Cevabı ve açıklamayı göster

Cevap: Reposition the client to a supine or right lateral position immediately.

Cevap

The nurse should immediately reposition the client to a supine or right lateral (operative side) position.
Following a pneumonectomy, the client must be positioned either supine or on the operative side (the right side, in this scenario). This position promotes maximum ventilation of the remaining healthy lung by preventing mediastinal shift and fluid compression. If the client lies on the unoperated side, gravity pulls the fluid accumulating in the empty surgical cavity downward, which compresses the remaining functional lung and can lead to sudden respiratory failure. It also increases the risk of fluid drowning the good lung if the bronchial stump sutures rupture.

Adım Adım Çözüm

1
Analyze the client's surgical procedure and current position.
The client had a right-sided pneumonectomy but is positioned on the left (unoperated) side.
Identifying the mismatch between the surgical site and the current position is the first step in recognizing physiological risk.
2
Evaluate the clinical assessment findings against expected postoperative norms.
Absent right-sided breath sounds, no chest tube, and a right-deviated trachea are all expected findings after a right pneumonectomy.
Differentiating expected anatomical changes from emergency complications (like tension pneumothorax) prevents unnecessary interventions.
3
Determine the physiological consequence of the client's current position.
Lying on the unoperated left side allows gravity to pull mediastinal fluid downward, compressing the only functioning lung and risking a bronchial stump leak.
Understanding the mechanism of injury dictates the priority intervention.
4
Select the immediate intervention that eliminates the mechanical threat.
Repositioning the client to the supine or operative (right) side immediately relieves the compression on the remaining lung.
According to the ABCs (Airway, Breathing, Circulation), resolving a mechanical obstruction to breathing takes priority over further assessment or notification.

Cevap

The most appropriate action is to place the client in a left-side-lying position with the head of the bed elevated.
For a client with unilateral pneumonia, the nurse should position the client with the unaffected lung dependent (down). Gravity directs greater blood flow to the dependent lung. By placing the healthy left lung down, blood flow is directed to the area with the best ventilation, which optimizes the ventilation-perfusion (V/Q) ratio and improves oxygenation.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client is an older adult with right-sided pneumonia, shallow breathing, and fatigue.
Understanding the location of the pulmonary pathology (right lung) is essential for determining safe and effective positioning.
2
Evaluate the physiological impact of positioning on oxygenation.
Positioning the client with the healthy lung dependent (left side down) maximizes blood flow to the well-ventilated lung due to gravity.
This 'good lung down' strategy optimizes the ventilation-perfusion (V/Q) match, thereby improving systemic oxygenation and reducing respiratory distress.
3
Identify and eliminate contraindicated actions.
Right-side-lying worsens hypoxia; assessing lung sounds cannot be delegated to a UAP; and acute agitation is a sign of hypoxia, not normal aging.
Ensuring safe delegation, recognizing signs of clinical deterioration, and avoiding harmful positions are core nursing responsibilities.

Cevap: Secure the perimeter of the spill and instruct a nearby staff member to obtain the hazardous drug spill kit.

Cevap

The correct action is to secure the perimeter of the spill and instruct a nearby staff member to obtain the hazardous drug spill kit.
When a hazardous medication, such as an antineoplastic agent, spills in a clinical area, the immediate priority is to prevent human exposure and cross-contamination. The nurse must stay with the spill to establish a safe perimeter and verbally instruct a colleague to retrieve the facility's hazardous drug spill kit. This ensures the spill is never left unattended while the proper protective and cleaning equipment is gathered.

Adım Adım Çözüm

1
Identify the primary hazard in the scenario.
A cytotoxic medication (doxorubicin) has spilled in a public/high-traffic area (hallway).
Antineoplastic agents are highly toxic, and exposure can cause significant harm to anyone who comes into contact with them.
2
Determine the immediate priority based on safety principles.
The nurse must protect others from exposure by isolating the area, rather than immediately cleaning it or abandoning it.
Leaving the spill unguarded allows for accidental exposure, while attempting to clean it without the spill kit exposes the nurse.
3
Select the option that fulfills the safety priority.
Securing the perimeter and calling for the specialized spill kit is the safest initial action.
This action simultaneously protects the public and initiates the proper cleanup protocol without endangering the nurse.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to place weight on the crutches, step up with the unaffected right leg, transfer weight to the right leg, bring the crutches and affected left leg up, and finally re-establish a stable tripod base.
When teaching a client to ascend stairs with a three-point gait, the nurse must emphasize the principle of 'up with the good.' The safe sequence begins by the client placing full weight on the crutches. Next, the unaffected (right) leg is advanced up to the stair. The client then transfers their body weight onto the strong right leg. Following this, the crutches and the affected (left) leg are brought up together to the same step. Finally, the client must ensure a stable tripod position is re-established before taking the next step. This sequence ensures safety, maintains balance, and prevents accidental weight-bearing on the affected limb.

Adım Adım Çözüm

1
Place body weight entirely onto the crutches.
The client's weight is fully supported by the upper body.
This removes weight from both legs, allowing the strong leg to move freely.
2
Advance the unaffected right leg up onto the step.
The right foot is securely placed on the higher surface.
The strong leg must go up first to provide the power needed to lift the body's center of gravity ('up with the good').
3
Transfer body weight from the crutches to the unaffected right leg.
The right leg now bears the body's weight.
Shifting weight to the planted strong leg allows the client to lift the crutches and the affected limb safely.
4
Bring the crutches and the affected left leg up to the same step.
Both feet and the crutches are now on the same stair.
The crutches and the affected leg move together as a single unit to ensure continuous support and protection of the injured limb.

Cevap: Heart rate of 118 beats per minute; Restlessness and anxiety

Cevap

The early signs of hypovolemic shock include a heart rate of 118 beats per minute and restlessness and anxiety.
In the early (compensatory) stage of hypovolemic shock, the body's sympathetic nervous system activates to maintain perfusion. This leads to an increased heart rate (tachycardia) to boost cardiac output. Additionally, early cerebral hypoxia and adrenaline release frequently manifest as restlessness, agitation, or anxiety.

Adım Adım Çözüm

1
Analyze the client's condition and risk factors.
The client is postoperative and at risk for hemorrhage, which can rapidly lead to hypovolemic shock.
Identifying the primary clinical risk helps anticipate the body's physiological compensatory mechanisms.
2
Identify the body's early physiological adaptation to fluid loss.
The sympathetic nervous system activates, causing tachycardia, peripheral vasoconstriction, and fluid retention.
Compensatory mechanisms attempt to maintain cardiac output and tissue perfusion.
3
Evaluate each option against early shock manifestations.
Tachycardia and restlessness are early signs. Warm skin and increased urine output are incorrect.
Blood is shunted from the skin (causing it to be cool) and kidneys (decreasing urine output) to protect vital internal organs.

Cevap

The correct sequence is: Position the client, lubricate the tubing, insert the tubing, elevate the container to administer fluid, and finally withdraw the tube while encouraging retention.
Administering a cleansing enema requires a systematic approach to ensure safety and effectiveness. The nurse must first place the client in the left lateral Sims position to align the sigmoid colon with gravity. Next, the equipment is prepared by lubricating the tip to prevent mucosal trauma. The tube is then inserted 3 to 4 inches into the rectum, aiming toward the umbilicus to follow the bowel's contour safely. Following correct placement, the fluid container is elevated 12 to 18 inches above the anus to initiate a steady, low-pressure flow. Finally, the tube is removed, and the client is instructed to retain the fluid to maximize the therapeutic outcome.

Adım Adım Çözüm

1
Position the client in a left lateral Sims position with the right knee flexed.
The client's gastrointestinal anatomy is optimally aligned for the procedure.
This position allows gravity to help the fluid flow smoothly into the descending colon and sigmoid colon.
2
Lubricate the distal 2 to 3 inches of the enema tubing tip.
The tubing is prepared for atraumatic insertion.
Lubrication reduces friction and prevents mucosal tearing or irritation.
3
Insert the enema tube gently 3 to 4 inches into the rectum, directing it toward the umbilicus.
The tube successfully and safely bypasses both the external and internal anal sphincters.
This depth and angle respect adult anatomy and prevent accidental bowel perforation.
4
Elevate the fluid container 12 to 18 inches above the client's anus and unclamp the tubing.
The enema fluid begins to flow into the rectum at a safe, controlled rate.
This specific height provides adequate pressure for infusion without causing painful bowel spasms.
5
Withdraw the tube smoothly and encourage the client to retain the enema fluid as prescribed.
The procedure concludes, allowing the fluid to take therapeutic effect.
Retaining the fluid provides necessary time for the stool to soften and for the bowels to be stimulated for evacuation.

A nurse is caring for a client receiving total parenteral nutrition (TPN) via a central venous catheter (CVC). During a tubing change, the CVC accidentally disconnects from the injection cap. The client suddenly gasps, reports sharp chest pain, and exhibits dyspnea with cyanosis. Arrange the following risk-reduction actions in the chronological order the nurse must perform them to manage this complication.

Cevap

The correct chronological sequence is: 1) Occlude the catheter, 2) Position in left lateral Trendelenburg, 3) Administer 100% oxygen, 4) Activate the rapid response team, and 5) Monitor vital signs continuously.
In the event of a suspected air embolism from a disconnected CVC, the nurse's priority sequence is designed to stop the embolus, trap it safely, treat the systemic effects, and get advanced help. Clamping the line directly stops the source of air entry. The left lateral Trendelenburg position mechanically traps the air in the right ventricle. Oxygen therapy then treats hypoxemia and helps dissolve the nitrogen in the air bubble. Finally, escalating care and monitoring are required for advanced management.

Adım Adım Çözüm

1
Identify the complication as a suspected air embolism.
The client's sudden dyspnea, chest pain, and cyanosis upon CVC disconnection strongly indicate an air embolism.
Recognizing the life-threatening complication dictates the immediate emergency response.
2
Prioritize interventions that mechanically stop further harm.
Clamping the catheter is identified as the first and most critical action.
According to strict prioritization principles, stopping the source of ongoing injury takes precedence over all other interventions.
3
Determine the next mechanical intervention to prevent the embolus from causing a blockage.
Positioning the client in the left lateral Trendelenburg position is selected.
This specific position utilizes gravity and cardiac anatomy to keep the air bubble trapped in the right ventricle, away from the pulmonary valve.
4
Address the client's severe oxygenation needs.
Administering 100% oxygen is the third action.
Once the physical threat of further air entry and movement is mitigated, treating the hypoxemia and promoting nitrogen resorption is critical.
5
Summon advanced help and provide ongoing assessment.
Activating the rapid response team, followed by continuous monitoring, completes the immediate sequence.
Advanced interventions require a healthcare provider, and continuous monitoring ensures further physiological decompensation is caught immediately.

Anahtar Kavram

Management of a suspected air embolism in a central venous catheter requires immediate mechanical occlusion, specific anatomical positioning to trap the air, high-flow oxygen administration, and rapid escalation of care.

Cevap

The correct sequence for IV piggyback setup is to first reconstitute the medication, inject it into the secondary dilution bag, prime the secondary tubing, asepticize the proximal Y-site port, and finally connect the tubing while lowering the primary fluid bag.
Establishing a secondary IV piggyback infusion requires a precise chronological workflow to ensure pharmacological safety and mechanical function. The medication must first be reconstituted from its powder form and then injected into the secondary bag for proper dilution. Before connecting anything to the patient's existing line, the secondary tubing must be spiked and primed to eliminate air. Aseptic technique dictates scrubbing the proximal Y-site port (above the pump, to ensure the pump regulates the rate) before attachment. Finally, the mechanical principles of gravity-fed infusion require lowering the primary fluid bag so the higher secondary bag exerts greater hydrostatic pressure, ensuring the pump draws the medication first.

Adım Adım Çözüm

1
Reconstitute the antibiotic powder.
The solid medication is transformed into a concentrated liquid solution.
Lyophilized powders must be dissolved in a sterile diluent before they can be added to larger fluid volumes.
2
Inject the reconstituted drug into the secondary IV bag.
The medication reaches the appropriate therapeutic concentration for infusion.
Direct administration of concentrated reconstituted medication can cause severe phlebitis or speed shock; it requires proper dilution.
3
Prime the secondary IV tubing.
Air is completely removed from the secondary line.
Purging air from the tubing is an essential safety requirement to prevent a potentially fatal air embolism.
4
Scrub the primary tubing Y-site port above the pump.
The connection site is sterilized.
Accessing any IV port without rigorous disinfection introduces a high risk of bloodstream infections.
5
Attach the secondary line, lower the primary bag, and open the clamp.
The secondary infusion is ready to be delivered by the pump.
Because the pump draws fluid from the highest source, the primary bag must be positioned lower than the secondary bag for the piggyback medication to infuse first.

Anahtar Kavram

Safe intravenous piggyback (IVPB) administration requires sequential reconstitution, dilution, line priming, aseptic connection at a proximal port, and gravity-assisted flow prioritization.
