Question 1221Question →

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?

Show answer & explanation

Answer: Prepare to administer the prescribed naloxone.

Answer

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.

Step-by-Step Solution

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.

Question 1222Question →

A nurse is preparing to administer an intermittent enteral tube feeding to a client via a percutaneous endoscopic gastrostomy (PEG) tube. Place the following nursing actions in the correct sequence to ensure safe administration.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

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.

Step-by-Step Solution

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.

Question 1223Question →

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?

Show answer & explanation

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

Answer

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.

Step-by-Step Solution

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.

Question 1224Question →

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?

Show answer & explanation

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

Answer

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.

Step-by-Step Solution

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.

An 82-year-old resident in a long-term care facility receives continuous enteral nutrition via a percutaneous endoscopic gastrostomy (PEG) tube. The nursing staff observes that the resident has recently developed sudden-onset confusion, frequent bowel incontinence, and worsening sacral erythema. Which action by the registered nurse demonstrates safe practice regarding the client's basic care and comfort?

Show answer & explanation

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

Answer

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.

Step-by-Step Solution

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.

An orthopedic nurse is reviewing postoperative orders for a client who underwent a right total hip arthroplasty using a posterolateral approach. To minimize the risk of prosthesis dislocation, which interventions should the nurse include in the daily care plan? Select all that apply.

Select all that apply

Show answer & explanation

Answer: 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.

Answer

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.

Step-by-Step Solution

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.

Question 1227Question →

A nurse assumes care for a client who is 4 hours postoperative following a right-sided pneumonectomy for bronchogenic carcinoma. The client has no chest tube in place. Current vital signs are: heart rate 112/min, respiratory rate 24/min, blood pressure 118/76 mm Hg, and SpO2 93% on 3 L/min of oxygen via nasal cannula. 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?

Show answer & explanation

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

Answer

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.

Step-by-Step Solution

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.

Key Concept

Post-pneumonectomy positioning requires placing the client on the operative side or supine to facilitate expansion of the remaining lung and prevent mediastinal compression.
Question 1228Question →

A 72-year-old individual is receiving treatment on the medical-surgical floor for right-sided bacterial pneumonia. The client exhibits shallow breathing, generalized weakness, and expresses feeling exhausted from continuous coughing. What is the most appropriate action for the registered nurse to take?

Show answer & explanation

Answer: Place the individual in a left-side-lying position with the head of the bed elevated.

Answer

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.

Step-by-Step Solution

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.

Key Concept

Therapeutic positioning to optimize ventilation-perfusion matching in unilateral lung disease.

A nurse is caring for a client receiving intravenous (IV) fluids. The client suddenly develops shortness of breath, a cough, and crackles in the lung bases. Arrange the following nursing actions in the priority order they should be performed.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to elevate the head of the bed, decrease the IV fluid rate, administer oxygen, and then notify the healthcare provider.
In acute decompensation from fluid volume overload, the nurse must follow the airway, breathing, and circulation (ABC) prioritization framework. Elevating the head of the bed immediately improves breathing mechanics. Stopping or slowing the IV fluid prevents further circulatory overload. Administering oxygen supports gas exchange. Finally, notifying the provider is essential to obtain further medical orders once initial stabilization is complete.

Step-by-Step Solution

1
Elevate the head of the bed to a high-Fowler's position.
Improves lung expansion and decreases venous return.
Airway and breathing are the highest priority. Sitting the client up provides the fastest relief for dyspnea.
2
Decrease the intravenous fluid infusion rate.
Stops the infusion of excess volume.
Circulation is the next priority. Slowing the IV fluids prevents the fluid overload from becoming more severe.
3
Administer supplemental oxygen.
Increases oxygen saturation in the blood.
Hypoxia must be treated to ensure adequate tissue perfusion.
4
Notify the healthcare provider.
Facilitates further medical intervention.
Once the client is temporarily stabilized, the provider must be informed to obtain prescriptions for medications like loop diuretics.

Question 1230Question →

A nurse is instructing a client who is non-weight-bearing on the left leg due to a fractured tibia on how to safely ascend a flight of stairs using crutches. Arrange the following steps of a three-point gait in the correct sequential order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

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.

Step-by-Step Solution

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.
5
Establish a stable tripod base of support before initiating the next step.
The client achieves stable equilibrium.
A proper tripod stance prevents falls and prepares the client's alignment for the subsequent step.

Key Concept

Ascending stairs with crutches requires the 'up with the good' sequence, utilizing the unaffected leg to lift the body's weight.
Question 1231Question →

A nurse is assessing a client who is postoperative and at risk for hemorrhage. Which of the following clinical findings indicate the client is developing early hypovolemic shock? Select all that apply.

Select all that apply

Show answer & explanation

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

Answer

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.

Step-by-Step Solution

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.

Question 1232Question →

A nurse is preparing to administer a large-volume cleansing enema to an adult client to relieve constipation. Arrange the following procedural steps in the correct chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

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.

Step-by-Step Solution

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.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

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.

Step-by-Step Solution

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.

Key Concept

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.
Question 1234Question →

A nurse is preparing to administer a prescribed intravenous (IV) piggyback dose of a reconstituted antibiotic. The client has a continuous primary IV infusion of 0.9%0.9\% sodium chloride running via an electronic infusion pump. Arrange the following steps in the correct chronological order to safely prepare and initiate the secondary IV piggyback infusion. All steps must be used.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

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.

Step-by-Step Solution

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.

Key Concept

Safe intravenous piggyback (IVPB) administration requires sequential reconstitution, dilution, line priming, aseptic connection at a proximal port, and gravity-assisted flow prioritization.
Question 1235Question →

A nurse is preparing to administer an intravenous (IV) push medication through a client's peripheral IV saline lock. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to perform hand hygiene and don gloves, scrub the injection port, flush the line with normal saline to check patency, inject the medication over the prescribed time, and finally flush the line again with normal saline.
The standard and safest sequence for administering an IV push medication through a saline lock follows strict infection control protocols and the established SAS (Saline-Administer-Saline) method. The nurse must first perform hand hygiene and don gloves to protect both the patient and themselves. Next, the injection port is scrubbed to prevent introducing pathogens. The initial flush with normal saline is critical to confirm the line is patent and not infiltrated. After patency is established, the medication is safely injected at the prescribed rate. Finally, a subsequent saline flush is necessary to clear the medication from the line, ensuring the patient receives the complete dose and preventing catheter occlusion.

Step-by-Step Solution

1
Ensure infection control.
Hand hygiene is performed and clean gloves are donned.
This is the fundamental first step in any invasive procedure to maintain standard precautions.
2
Disinfect the access point.
The IV injection port is scrubbed with an antiseptic swab.
Prevents the introduction of microorganisms into the patient's bloodstream.
3
Assess IV patency.
The IV catheter is flushed with 0.9% sodium chloride.
Ensures the vein is viable, the line is not occluded, and prevents administering medication into infiltrated tissue.
4
Administer the therapeutic agent.
The medication is injected over the recommended duration.
Delivers the required dose safely and minimizes the risk of speed shock or localized irritation.
5
Clear the line and ensure full dosing.
A final flush of 0.9% sodium chloride is administered.
Pushes the remaining medication in the extension tubing into the systemic circulation and locks the line to maintain future patency.

Safe administration of IV push medications via a saline lock using the SAS (Saline-Administer-Saline) method.
Question 1236Question →

A nurse is receiving a client who just underwent a bedside thoracentesis for a large right-sided pleural effusion. Which of the following nursing actions are essential to monitor and reduce the risk of post-procedure complications? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Evaluate the client for tracheal deviation toward the unaffected side and sudden onset of dyspnea.; Auscultate bilateral breath sounds to detect diminished or absent aeration on the right side.; Instruct the client to immediately report any new onset of severe coughing or blood-tinged sputum.

Answer

The essential actions are evaluating for tracheal deviation and dyspnea, auscultating bilateral breath sounds, and instructing the client to report severe coughing or blood-tinged sputum.
Following a thoracentesis, the nurse must prioritize assessments that detect potentially fatal complications such as a tension pneumothorax or hemothorax. Tracheal deviation, sudden dyspnea, absent breath sounds, severe coughing, and hemoptysis are critical indicators of lung puncture or pulmonary hemorrhage. Recognizing these findings immediately reduces the risk of severe physiological injury.

Step-by-Step Solution

1
Identify the primary risks associated with a thoracentesis.
The most significant post-procedure risks include pneumothorax, bleeding (hemothorax), infection, and re-expansion pulmonary edema.
Understanding the anatomical risks (puncture of lung tissue or vessels) directs the nurse's focused assessment.
2
Select interventions that actively monitor for or prevent these specific risks.
Assessing for tracheal deviation, absent breath sounds, and hemoptysis directly monitors for a pneumothorax or internal bleeding.
Prompt recognition of these adverse events allows for life-saving interventions.
3
Eliminate inappropriate or dangerous actions.
Dismissing early signs of shock, placing the patient flat, and delegating the initial critical assessment are eliminated.
These actions increase the client's risk of severe physiological decompensation and violate core safety standards.

A nurse is monitoring a client with severe hepatic cirrhosis who is undergoing a large-volume therapeutic paracentesis. After 3.5 liters of ascitic fluid have been drained, the client reports sudden dizziness and nausea. The client's heart rate increases from 82 to 124 beats per minute, and the blood pressure drops from 130/84 mm Hg to 92/58 mm Hg. Which action should the nurse take first to reduce the risk of further physiological deterioration?

Show answer & explanation

Answer: Clamp the drainage tubing immediately to stop further fluid removal.

Answer

Clamp the drainage tubing immediately to stop further fluid removal.
The correct action directly addresses the root cause of the client's hemodynamic instability. Rapid removal of large volumes of ascitic fluid can lead to a sudden shift of fluid from the intravascular space into the peritoneal cavity, causing hypovolemia and shock. Clamping the tube immediately stops this process, preventing further cardiovascular collapse.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client has tachycardia, hypotension, dizziness, and nausea after the removal of a large volume of ascitic fluid.
Identifying these signs indicates paracentesis-induced circulatory dysfunction, a form of hypovolemic shock caused by rapid fluid shifts from the intravascular space.
2
Determine the priority intervention.
The immediate priority is to halt the process causing the fluid shift.
Clamping the drainage tubing prevents further volume loss and allows the cardiovascular system to stabilize.

Show answer & explanation

Answer

The correct sequence is to first clean and dry the site, puncture the lateral fingertip, wipe away the first drop of blood, apply the second drop to the test strip, and finally apply pressure to the site.
Obtaining a capillary blood glucose measurement requires strict adherence to technique to ensure both client safety (infection prevention) and clinical accuracy (preventing altered readings). The site must first be cleaned and completely dried. Puncturing the lateral side of the finger minimizes pain. Wiping away the first drop of blood is a critical step because it may be diluted with serous fluid or remaining alcohol. The second drop is then applied to the test strip for a highly accurate reading, followed immediately by applying pressure to the site to stop bleeding and prevent bruising.

Step-by-Step Solution

1
Clean the selected puncture site with an alcohol swab and allow it to air dry.
The skin is sanitized and free of wet alcohol.
Reduces infection risk and prevents alcohol from chemically altering the glucose reading.
2
Puncture the lateral aspect of the fingertip with a sterile lancet.
A small capillary puncture is created.
The lateral side of the finger is less painful for the client due to fewer nerve endings.
3
Wipe away the first drop of blood using a clean, dry gauze pad.
The initial, potentially diluted blood drop is removed.
The first drop may contain interstitial fluid or alcohol residue, causing inaccurate glucose results.
4
Apply the second drop of blood to the reagent test strip.
An accurate blood sample is collected for testing.
The second drop provides a pure capillary sample for the most accurate measurement.
5
Apply direct pressure to the puncture site with a cotton ball or gauze pad.
Bleeding is stopped.
Maintains skin integrity and prevents continued bleeding or localized bruising.

A nurse is preparing to administer an intermittent secondary intravenous (IV) piggyback medication using a new sterile administration set. The client is currently receiving a continuous primary IV fluid infusion via an electronic pump. Arrange the following actions in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to verify medication compatibility, close the secondary tubing's roller clamp, spike the bag and prime the tubing, cleanse the primary tubing's upper Y-port, and finally connect the secondary tubing while lowering the primary IV fluid bag.
Administering a secondary intravenous (IV) piggyback medication requires a systematic approach to ensure patient safety and medication efficacy. First, the nurse must verify the compatibility of the secondary medication with the continuous primary IV fluid to prevent dangerous precipitates from forming. Next, the nurse closes the roller clamp on the new secondary tubing to prevent fluid from freely flowing out when the bag is spiked. The bag is then spiked, and the tubing is primed to expel all air, which prevents an air embolism. Following preparation of the tubing, the nurse maintains strict asepsis by cleansing the upper Y-port (the port above the infusion pump) on the primary line with an antimicrobial swab. Finally, the secondary tubing is connected to the cleansed port, and the primary fluid bag is lowered using an extension hanger. Because the secondary bag is hung higher, gravity allows it to exert greater hydrostatic pressure, ensuring the secondary medication infuses first while temporarily halting the primary infusion until the secondary bag is empty.

Step-by-Step Solution

1
Verify compatibility.
Ensures the secondary medication will not form a precipitate when it mixes with the primary IV fluid.
Patient safety is the highest priority; incompatible medications can cause life-threatening complications.
2
Close the roller clamp.
The secondary tubing is closed off to fluid flow.
Prevents the medication from immediately spilling out when the fluid bag is spiked.
3
Spike the bag and prime the tubing.
Air is completely removed from the secondary tubing.
Expelling air from the intravenous line prevents an air embolism from reaching the client's vascular system.
4
Cleanse the upper Y-port.
The connection site above the infusion pump is disinfected.
Vigorously scrubbing the needleless port maintains asepsis and prevents the introduction of pathogens into the bloodstream.
5
Connect the tubing and lower the primary bag.
The secondary medication is ready to infuse first.
Gravity causes the fluid in the higher bag (secondary) to exert greater hydrostatic pressure, allowing it to infuse while temporarily halting the flow of the lowered primary bag.

Question 1240Question →

A nurse is receiving a client who has just returned to the clinical unit after undergoing a diagnostic lumbar puncture. The client reports the onset of a mild headache. Which of the following positioning interventions should the nurse implement?

Show answer & explanation

Answer: Keep the client in a supine position with the head of the bed flat.

Answer

Keep the client in a supine position with the head of the bed flat.
After a lumbar puncture, the client is at risk for developing a post-dural puncture headache (spinal headache) due to the leakage of cerebrospinal fluid (CSF) from the puncture site. Keeping the client in a flat, supine position minimizes hydrostatic pressure and CSF leakage, which helps prevent or alleviate the headache.

Step-by-Step Solution

1
Analyze the client's procedure and current symptom.
The client had a lumbar puncture and is now experiencing a mild headache.
Identifying the procedure and symptoms is essential to determine the appropriate post-procedure care.
2
Recall the pathophysiology of a post-lumbar puncture headache.
A headache following this procedure is typically caused by the continuous leakage of cerebrospinal fluid (CSF) through the dural puncture site.
Understanding the cause of the complication guides the nursing intervention.
3
Determine the optimal positioning to manage this complication.
A flat, supine position minimizes hydrostatic pressure on the dural tear and reduces CSF leakage.
Keeping the spine horizontal prevents gravity from exacerbating the fluid loss, thereby helping to relieve or prevent the headache.
