Prior to providing direct care for a newly admitted client with confirmed pulmonary tuberculosis and a secondary scabies infection, a practical nurse must apply multiple forms of personal protective equipment. The client requires airborne and contact precautions, along with eye protection due to a planned wound irrigation. In what order should the nurse don the necessary protective items?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for donning personal protective equipment is: Hand hygiene, followed by the isolation gown, the N95 respirator, eye protection, and finally, gloves.
According to the Centers for Disease Control and Prevention (CDC) guidelines, donning personal protective equipment must follow a specific sequence to optimize safety and barrier integrity. Hand hygiene is always the critical first step. The gown is applied next to cover the torso and arms. The N95 respirator follows, allowing it to seal directly against the face. Eye protection is then added without disrupting the respirator seal. Finally, gloves are donned and pulled completely over the gown cuffs to seal the wrists.

Step-by-Step Solution

1
Identify the first action required to prevent contamination of clean supplies.
Perform hand hygiene.
Hands must be clean before touching any unused personal protective equipment from the isolation cart.
2
Determine the first physical barrier to apply to the body.
Apply the isolation gown.
The gown provides core body coverage and is easiest to tie securely before applying other equipment to the face.
3
Identify the primary respiratory protection needed for airborne precautions.
Don the N95 respirator.
The respirator must be fitted directly against the skin for a secure seal before placing any eyewear.
4
Determine the next facial protection needed for the wound irrigation.
Place the face shield or goggles.
Eye protection is placed over or alongside the respirator without breaking the mask's protective seal.
5
Identify the final step for contact protection.
Put on clean gloves.
Gloves go on last so they can be pulled up over the gown cuffs, ensuring no skin on the wrists is exposed to pathogens.

Key Concept

The standardized Centers for Disease Control and Prevention (CDC) sequence for donning personal protective equipment ensures maximum infection control by preventing self-contamination and creating continuous physical barriers.
Question 162Question →

A practical nurse is preparing to provide oral hygiene to a client who remains unconscious following a prolonged surgical procedure. Arrange the following actions in the chronological order they must be performed to maintain client safety. (Assume hand hygiene and donning of gloves are complete.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes airway safety: position the client side-lying, place protective linens/basin, safely open the mouth with a tongue blade, perform the oral cleansing, and finally moisturize the lips.
When providing basic care to an unconscious client, the absolute priority is maintaining a patent airway and preventing aspiration. Placing the client in a side-lying position must occur before any other step. After safety is established, the nurse protects the bed and clothing, safely gains access to the mouth to avoid reflex injuries, performs the actual cleansing, and completes the procedure by applying moisturizer for comfort.

Step-by-Step Solution

1
Ensure an open and safe airway.
The client is positioned on their side.
A side-lying position uses gravity to help oral secretions and cleaning fluids drain out of the mouth, significantly reducing the risk of aspiration into the lungs.
2
Protect the client and bedding.
A towel and emesis basin are placed in position.
Gathering and placing supplies keeps the client clean, dry, and comfortable during the procedure.
3
Gain safe access to the oral cavity.
A padded tongue blade is used to separate the upper and lower teeth.
An unconscious client may have a strong involuntary bite reflex. A padded tongue blade safely keeps the mouth open without risking injury to the nurse's fingers or the client's teeth.
4
Perform the hygiene procedure.
The oral cavity is cleansed.
Thorough cleaning removes plaque and bacteria, which prevents hospital-acquired infections like pneumonia.
5
Provide final skin care.
Water-soluble moisturizer is applied to the lips.
Unconscious clients often breathe through their mouths, leading to dry and cracked lips. A water-soluble product provides safe moisture.

Question 163Question →

A practical nurse (PN) is preparing to implement a new prescription for mechanical wrist restraints for a client who is severely agitated and attempting to remove their central venous catheter. Place the following nursing actions in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first confirm the provider's prescription, then discuss the rationale with the client, apply protective padding to the wrists, fasten the straps to the movable section of the bed frame using a quick-release knot, and finally evaluate the client's neurovascular status distal to the device.
The correct sequence follows the standard of care for restrictive device application. Verification of the legal order ensures authorization; communication respects client rights; padding prevents skin breakdown during application; securing to an articulating frame with a slip knot ensures physical safety; and immediate neurovascular assessment confirms the device is not overly restrictive.

Step-by-Step Solution

1
Confirm the provider's written prescription and specific clinical indications.
Verification that a valid, current legal order exists for the restrictive device.
Restraints require a valid provider order outlining the specific type and duration; they cannot be applied on a PRN (as needed) basis.
2
Discuss the rationale for the safety device with the client.
The client is informed about why the intervention is necessary.
Providing education respects the client's rights, reduces fear, and may increase cooperation even if the client is agitated.
3
Place protective padding around the client's wrists.
The bony prominences of the wrists are cushioned.
Padding minimizes friction and pressure, which prevents skin breakdown and tissue injury during device use.
4
Fasten the device straps to the articulating section of the bed using a slip knot.
The device is securely anchored to a safe location with a quick-release mechanism.
Securing straps to an articulating (movable) section prevents injury when the bed position is adjusted, and a slip knot ensures rapid removal in an emergency. They must never be tied to side rails.
5
Evaluate distal perfusion, sensation, and motor function.
The neurovascular status of the extremity is documented immediately after application.
Immediate assessment ensures the device is not applied too tightly, which could severely compromise blood flow or cause nerve damage.

Key Concept

Safe application of physical restraints requires a systematic approach beginning with legal order verification, followed by client education, proper physical application techniques to prevent injury, and immediate post-application neurovascular assessment.

Arrange the steps for donning the required personal protective equipment (PPE) in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Perform hand hygiene, put on the gown, apply the surgical mask, position the face shield or goggles, and finally put on the gloves.
According to the Centers for Disease Control and Prevention (CDC) guidelines, the correct sequence for donning PPE is to perform hand hygiene first, followed by the gown. The mask or respirator is applied next, followed by eye protection (goggles or face shield). Gloves are always put on last so they can be extended to cover the wrist cuffs of the isolation gown, ensuring no skin is exposed.

Step-by-Step Solution

1
Identify the required precautions for RSV.
The nurse determines that contact and droplet precautions require a gown, surgical mask, eye protection, and gloves.
Knowing the correct PPE items is essential before beginning the donning process.
2
Apply the CDC recommended sequence for donning PPE.
The nurse sequences the steps starting with hand hygiene, followed by the gown, mask, eye protection, and finally gloves.
Following the standardized sequence prevents contamination of clean equipment and ensures all barriers (like the glove-over-gown seal) are properly established.

A client with a suspected lower respiratory tract infection requires a sputum specimen for culture and sensitivity testing. To minimize the risk of sample contamination with oral flora, which sequence of steps should the practical nurse follow? Arrange the actions in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with oral preparation (rinsing), followed by lung expansion (deep breathing), mobilization of secretions (coughing), collection (expectorating), and finally securing the specimen (sealing and labeling).
Following the chronological order of rinsing the mouth, performing deep breathing, coughing deeply, expectorating into the container, and immediately sealing it ensures the specimen is uncontaminated and accurately reflects the lower respiratory tract environment.

Step-by-Step Solution

1
Instruct the client to rinse the mouth with plain water without swallowing.
Reduces oral flora in the mouth.
Decreases the risk of contaminating the specimen with normal mouth bacteria.
2
Ask the client to take several slow, deep breaths to expand the lungs.
Maximizes lung expansion.
Helps loosen secretions in the lower respiratory tract.
3
Direct the client to perform a deep, forceful cough to mobilize lower airway secretions.
Moves sputum upward.
Ensures the sample is from the lungs, not just saliva from the upper airway.
4
Have the client expectorate the mobilized secretions directly into the sterile container.
Captures the sterile specimen.
Avoids outside contamination by collecting directly into the sterile environment.
5
Secure the lid on the container immediately and apply the client's identification label.
Seals and identifies the sample.
Maintains specimen integrity and ensures correct client identification for laboratory processing.

Key Concept

To ensure diagnostic accuracy and reduce the risk of misdiagnosis due to sample contamination, a sputum specimen must be collected from the lower respiratory tract using a sterile technique and proper client preparation.
Question 166Question →

A practical nurse (PN) is assisting a healthcare provider with a bedside thoracentesis for a client who has a large pleural effusion. To ensure client safety and reduce the risk of procedural complications, in what order should the PN perform the following actions? (Arrange the steps from first to last.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Obtain baseline vital signs and respiratory assessment, 2) Position the client upright and leaning forward, 3) Instruct the client to remain still and not cough, 4) Apply a sterile dressing to the puncture site, and 5) Auscultate bilateral breath sounds.
Safe assistance during a thoracentesis follows a strict logical flow to reduce risk: establishing a clinical baseline, physically preparing the client via positioning, preventing injury during the active procedure by teaching the client not to move, immediately securing the skin breach afterward to prevent air entry, and finally evaluating the client for procedural complications.

Step-by-Step Solution

1
Obtain baseline vital signs and perform a focused respiratory assessment.
Pre-procedure baseline clinical data is established.
Accurate pre-procedure vitals and breath sounds are necessary to recognize subtle physiological changes or respiratory distress later.
2
Position the client sitting upright on the edge of the bed while leaning forward over an overbed table.
The client is secured in the orthopneic position.
This specific position opens the intercostal spaces, giving the provider clear access to the pleural fluid and minimizing the risk of visceral organ injury.
3
Instruct the client to remain completely still and refrain from coughing or talking during needle insertion.
The client understands how to cooperate safely during the invasive portion of the procedure.
Any sudden movement, such as coughing or taking a deep breath, can shift the lung tissue into the path of the needle, risking a traumatic pneumothorax.
4
Apply a sterile dressing to the puncture site once the needle is withdrawn.
The puncture site is immediately sealed and protected.
Immediate application of a sterile dressing prevents environmental contamination and blocks atmospheric air from entering the negative-pressure pleural cavity.
5
Auscultate bilateral breath sounds and monitor for asymmetrical chest expansion.
The client's post-procedure respiratory status is evaluated.
Comparing these findings to the baseline assessment helps the nurse rapidly identify complications, such as a pneumothorax or hemothorax, if breath sounds are diminished on the affected side.

Question 167Question →

A practical nurse is observing clients in a pediatric clinic's waiting area. Arrange the following observed play behaviors in chronological order from the earliest developmental stage to the most advanced.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence of play development is solitary play, followed by parallel play, then associative play, and finally cooperative play.
The development of play progresses sequentially as a child's cognitive and social skills mature. It begins with solitary play in infancy, advances to parallel play in toddlerhood, moves to associative play in the preschool years, and culminates in cooperative play during the school-age years.

Step-by-Step Solution

1
Identify the developmental stage associated with independent play using a rattle.
This behavior represents solitary play, which occurs in infancy (birth to 1 year).
Infants lack the cognitive and social development to interact meaningfully with peers during play, making this the earliest stage.
2
Identify the stage associated with playing beside, but not with, another child.
This behavior represents parallel play, typical of the toddler stage (1 to 3 years).
Toddlers are egocentric and aware of others but do not yet have the skills to coordinate joint play activities.
3
Identify the stage where children share materials and interact loosely without a common goal.
This behavior represents associative play, which is characteristic of the preschool age (3 to 6 years).
Preschoolers develop increased social awareness and begin interacting, but their play remains relatively unorganized.
4
Identify the stage involving structured games with rules and teamwork.
This behavior represents cooperative play, typical of school-age children (6 to 12 years).
School-age children have the cognitive ability to understand rules, take turns, and work toward a shared objective.

Question 168Question →

It is time for a client's scheduled transdermal fentanyl patch replacement. To ensure safe medication administration, arrange the following steps in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with verifying client identity, followed by removing the old patch while wearing gloves, preparing a new site, labeling the new patch, and finally applying it to the skin.
Safe transdermal medication administration requires strict adherence to a specific procedural sequence. Verifying identity ensures the intervention reaches the correct client. Removing the old patch first (while wearing gloves) prevents toxicity and nurse exposure. Preparing the new site promotes proper absorption and prevents skin breakdown. Labeling the patch prior to application prevents client discomfort from writing pressure. Finally, applying firm pressure secures the patch for its duration of use.

Step-by-Step Solution

1
Verify client identity and perform hand hygiene.
The correct client is confirmed and infection transmission risk is minimized.
This adheres to the basic rights of medication administration and standard safety precautions.
2
Don clean gloves and remove the old fentanyl patch.
The previous medication source is safely discontinued.
Gloves prevent the nurse from absorbing fentanyl dermally, and removing the old patch prevents accidental overdose.
3
Cleanse a new, hairless application site and let it dry.
A fresh area of skin is prepared for the new patch.
Rotating sites prevents skin breakdown. A clean, dry surface ensures the new patch will adhere properly and medication will absorb consistently.
4
Label the new patch with the date, time, and initials.
The patch is clearly marked before it goes on the client's body.
Writing on the patch after application can cause discomfort and may unintentionally push a bolus of medication into the client's tissues.
5
Remove the protective liner, apply to the skin, and press firmly for 30 seconds.
The new fentanyl patch is securely attached and actively delivering medication.
Firm pressure, especially around the edges, ensures the adhesive matrix bonds tightly to the skin for the entire duration of the order.

The client is sitting in a wheelchair nearby. Arrange the following emergency response actions in the correct priority sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence follows the RACE protocol: Move the client to safety (Rescue), pull the fire alarm (Alarm), close the room door (Contain), and obtain a fire extinguisher (Extinguish).
In the event of a fire in a healthcare facility, all staff must follow the RACE protocol. The first priority is always to Rescue or remove clients in immediate danger. The second step is to sound the Alarm to alert others and emergency services. The third step is to Contain the fire by closing doors and windows. The final step is to Extinguish the fire using an appropriate extinguisher, provided it is small and safe to do so.

Step-by-Step Solution

1
Move the client in the wheelchair out of the room to a designated safe zone.
The client is removed from immediate danger.
The 'R' in the RACE acronym stands for Rescue or Remove. Life safety is always the highest priority.
2
Pull the nearest manual fire alarm station to alert the facility.
The facility's emergency response system is activated.
The 'A' stands for Alarm. Once immediate safety is secured, alerting others ensures a coordinated facility response and dispatch of emergency services.
3
Close the door to the client's room to prevent the fire from spreading.
The fire and smoke are confined to the room of origin.
The 'C' stands for Contain or Confine. Closing doors removes the oxygen supply to the fire and protects the evacuation routes.
4
Obtain a fire extinguisher and attempt to put out the fire if it remains small.
The fire is actively fought if safe to do so.
The 'E' stands for Extinguish. This is the final step, performed only after clients are safe, the alarm is sounding, and the fire is contained.

Key Concept

The RACE protocol is the standard procedure for responding to a fire emergency in a healthcare facility: Rescue, Alarm, Contain, Extinguish.
Question 170Question →

After assisting a client who is positive for *Clostridioides difficile*, a practical nurse prepares to wash their hands with soap and water. Arrange the following steps of the hand hygiene procedure in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for hand hygiene is: wet hands keeping them below the elbows, apply soap, scrub vigorously for at least 20 seconds, rinse from wrists to fingertips, and finally dry the hands and turn off the faucet with a clean paper towel.
The standard CDC procedure for handwashing ensures that hands are cleaned effectively without recontaminating them or the arms. Wetting hands first creates a base for lather, friction removes microbes, downward rinsing washes them away safely, and using a separate towel for the faucet prevents recontamination from environmental surfaces.

Step-by-Step Solution

1
Wet hands and wrists
Skin is moistened and ready for soap application.
Wetting hands first minimizes skin irritation and helps the soap lather effectively. Keeping hands below elbows prevents contaminated water from flowing back up the arms.
2
Apply liquid soap
Soap is distributed on the hands.
Adequate soap ensures sufficient coverage of all hand surfaces for effective cleaning.
3
Scrub for at least 20 seconds
Pathogens and debris are mechanically loosened.
Friction is the most important component of handwashing. A minimum of 20 seconds is required to physically remove transient flora and spores like C. difficile.
4
Rinse from wrists to fingertips
Soap and pathogens are washed away into the sink.
Water must flow from the least contaminated area (wrists) to the most contaminated area (fingertips) to prevent recontamination.
5
Dry hands and turn off the faucet
Hands are dry and remain uncontaminated.
Drying prevents microbial growth in residual moisture. Using a separate, dry paper towel to turn off the faucet ensures clean hands do not touch the contaminated faucet handle.

A practical nurse is preparing to administer an intramuscular (IM) injection using the Z-track method to an adult client. Arrange the following steps for this procedure in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first perform hand hygiene and don gloves, then displace the skin laterally, insert the needle at a 90-degree angle, inject the medication slowly, and finally withdraw the needle while releasing the displaced skin.
The Z-track method is designed to prevent medication from leaking into the subcutaneous tissue. To perform this correctly, infection control (hand hygiene and gloves) is always the first step. Next, the nurse displaces the skin to misalign the tissue layers. While holding the skin displaced, the needle is inserted at 90 degrees to reach the muscle, and the medication is injected. Finally, the needle is withdrawn and the skin is released simultaneously to create a zig-zag track that seals the medication in the muscle.

Step-by-Step Solution

1
Ensure infection control
Hand hygiene is performed and gloves are donned.
To maintain standard precautions and prevent the transmission of microorganisms before touching the client.
2
Prepare the tissue using the Z-track technique
Skin and subcutaneous tissue are displaced laterally.
This creates a zig-zag path that will prevent the medication from leaking back up the needle track.
3
Puncture the skin
Needle is inserted at a 90-degree angle.
This angle is required to bypass the subcutaneous layer and deposit the medication directly into the deep muscle.
4
Administer the medication
Medication is injected slowly and steadily.
Slow administration promotes comfort and allows the muscle fibers to absorb the fluid volume.
5
Seal the injection track
Needle is withdrawn and the displaced skin is released.
Releasing the tissue seals the track, trapping the medication in the muscle and preventing skin irritation.

A practical nurse is preparing to withdraw a prescribed medication from a glass ampule. In what order should the nurse perform the following steps? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for withdrawing medication from an ampule begins with moving fluid to the bottom chamber, protecting the hands, breaking the ampule safely, using a filter needle to withdraw, and finally changing to an administration needle.
When preparing medication from an ampule, the priority is to ensure accurate dosage and safety from glass shards. First, tapping the ampule ensures all fluid is available to draw. Next, wrapping the neck protects the nurse's fingers, and breaking it away from the body protects the face. A filter needle is then essential to prevent aspirating glass particles. Finally, the filter needle must be discarded and replaced with a proper injection needle to ensure safe administration to the client.

Step-by-Step Solution

1
Tap the top of the ampule lightly.
Medication moves to the bottom chamber.
Ensures all medication is available for withdrawal and prevents spillage.
2
Wrap the neck with a sterile gauze pad or unopened alcohol swab.
The glass neck is safely covered.
Protects the nurse's fingers from sharp glass shards during opening.
3
Snap the neck of the ampule quickly and firmly away from the body.
The ampule is opened safely.
Prevents shattered glass from flying toward the nurse's face or body.
4
Withdraw the medication using a filter needle attached to the syringe.
Medication is drawn into the syringe without glass particles.
The filter needle traps any microscopic glass fragments that may have fallen into the liquid.
5
Replace the filter needle with an appropriate administration needle.
The syringe is safely prepared for client injection.
Filter needles are strictly for withdrawal and can cause severe tissue damage or inject trapped glass if used for administration.

A practical nurse is preparing to collect a sterile urine specimen for a culture and sensitivity test from a client who has an indwelling urinary catheter. Arrange the following procedural steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: clamp the tubing, scrub the port, withdraw the urine, transfer to the container, and unclamp the tubing.
Obtaining a sterile urine specimen from an indwelling catheter requires maintaining the closed drainage system to prevent infection and ensuring a fresh sample. First, the tubing is clamped to collect fresh urine. Next, the port is disinfected to prevent introducing microorganisms. Then, the sterile syringe is used to withdraw the sample, which is subsequently transferred to a sterile cup. Finally, the tubing must be unclamped immediately to restore continuous urinary flow and prevent bladder distension.

Step-by-Step Solution

1
Clamp the catheter drainage tubing just below the specimen collection port.
Fresh urine accumulates in the tubing.
Urine collected from the drainage bag is not sterile and cannot be used for a culture. Clamping ensures a fresh sample is available.
2
Scrub the needleless specimen collection port briskly with an antimicrobial swab.
The surface of the port is disinfected.
This prevents bacteria on the surface from entering the closed catheter system or contaminating the urine sample.
3
Attach a sterile syringe to the needleless port and withdraw the required volume of urine.
Urine is safely extracted from the tubing.
Using a needleless sterile syringe maintains the sterility of the closed drainage system while retrieving the sample.
4
Carefully transfer the aspirated urine into a sterile specimen container.
The sample is secured in a sterile environment.
Transferring the sample without touching the inside of the container keeps the urine uncontaminated for accurate laboratory analysis.
5
Unclamp the catheter drainage tubing and verify the unobstructed flow of urine.
Normal, continuous urine flow is restored.
Forgetting to unclamp the tubing can lead to urinary stasis, severe bladder distension, and an increased risk of infection.

A client receiving continuous enteral nutrition via a nasogastric tube suddenly experiences a severe bout of coughing accompanied by tachypnea and audible airway gurgling. To effectively reduce the risk of aspiration pneumonia and stabilize the client, arrange the following nursing actions in the correct priority sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate risk mitigation by stopping the pump and protecting the airway with positioning, followed by gathering assessment data, escalating to the registered nurse, and finally documenting the event.
This sequence adheres to the Airway, Breathing, Circulation (ABC) priority framework and the nursing process. Turning off the pump immediately removes the aspiration hazard. Positioning the client utilizes gravity to further protect the airway. Assessing vital signs provides essential objective data for the subsequent escalation to the registered nurse. Documentation finalizes the process once the client is stabilized and safe.

Step-by-Step Solution

1
Identify the immediate threat and turn off the enteral feeding pump.
The flow of enteral formula is halted.
Risk mitigation requires immediate cessation of the offending agent to prevent further aspiration.
2
Position the client upright in a high Fowler's position or on their side.
The airway is protected using gravity.
This prevents pooling of fluids in the pharynx and maximizes lung expansion.
3
Assess vital signs, lung sounds, and oxygen saturation.
Objective data regarding the respiratory compromise is gathered.
Accurate assessment dictates the urgency and type of further medical interventions required.
4
Report the clinical findings to the supervising registered nurse.
The healthcare team is alerted to the acute change in condition.
The practical nurse must escalate critical findings that require advanced orders, such as suctioning or imaging.
5
Document the event and all nursing actions taken.
A permanent legal record of the emergency is created.
Documentation finalizes the nursing process only after the client has been safely stabilized.

Question 176Question →

A practical nurse (PN) is preparing a single syringe containing both NPH insulin and regular insulin for a client with diabetes mellitus. In what order should the PN perform the following steps to safely prepare the medication? (Arrange the actions from first to last).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
When mixing NPH (intermediate-acting, cloudy) and regular (short-acting, clear) insulins, the standard safety protocol is 'clear before cloudy'. The correct sequence ensures the regular insulin vial is not contaminated by NPH insulin. First, the NPH suspension must be rolled to mix. Then, air is injected into the NPH vial, followed by air into the regular vial. The regular insulin is then withdrawn, and finally, the NPH insulin is withdrawn.

Step-by-Step Solution

1
Roll the NPH insulin vial gently between the palms of the hands.
The suspension is evenly mixed without creating bubbles.
NPH insulin contains particles that settle at the bottom and must be resuspended evenly for accurate dosing.
2
Inject an amount of air equal to the prescribed dose into the NPH insulin vial.
Air pressure in the NPH vial is increased without withdrawing medication.
Injecting air prevents a vacuum from forming when withdrawing the dose later. This is done first to avoid cross-contamination once the needle has regular insulin on it.
3
Inject an amount of air equal to the prescribed dose into the regular insulin vial.
Air pressure in the regular insulin vial is increased.
This prepares the regular insulin vial for immediate withdrawal of the medication.
4
Invert the regular insulin vial and withdraw the prescribed dose.
The correct dose of regular insulin is now in the syringe.
Regular (clear) insulin is always drawn up before NPH (cloudy) insulin to prevent the NPH insulin from contaminating the regular insulin vial, which could alter the action of the rapid-acting insulin.
5
Insert the needle into the NPH insulin vial and withdraw the prescribed dose.
The total mixed dose is now in the syringe.
The cloudy insulin is drawn up last to complete the mixture safely.

Question 177Question →

A practical nurse (PN) is in the room with a client who has a continuous intravenous infusion via a central venous catheter. The client suddenly gasps for air, becomes profoundly cyanotic, and reports acute, severe chest pain. Suspecting a central line air embolism, arrange the following nursing actions in the precise priority order the PN should perform them to mitigate the immediate risk of a fatal complication.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first clamp the catheter, then place the client in a left lateral Trendelenburg position, followed by administering high-flow oxygen, notifying the RN and rapid response team, and finally obtaining a complete set of vital signs.
In a suspected central line air embolism, the sequence of actions must prioritize immediate source containment and physiological mitigation before escalating the situation. Clamping the line instantly stops the cause. The left lateral Trendelenburg position (Durant's maneuver) is the definitive mechanical intervention to trap the air in the right ventricle, preventing a fatal pulmonary embolism. High-flow oxygen helps wash out nitrogen to shrink the embolus. Only after these rapid, life-saving measures are executed should the practical nurse take the time to escalate the emergency to the RN and Rapid Response Team, followed by continuous vital sign monitoring to prepare for their arrival.

Step-by-Step Solution

1
Clamp the central venous catheter immediately.
The source of the air embolus is instantly secured.
This is the most critical first step; it stops the ongoing influx of air into the central circulation, preventing the complication from worsening.
2
Place the client in a left lateral Trendelenburg position.
The air bubble is mechanically trapped.
Known as Durant's maneuver, this position keeps the buoyant air in the apex of the right ventricle, preventing it from migrating into the pulmonary circulation where it could cause sudden cardiac arrest.
3
Administer high-flow oxygen via a non-rebreather mask.
Hypoxia is treated and the bubble size may decrease.
Delivering 100% oxygen washes out nitrogen from the air bubble, helping to reduce its volume while aggressively treating the client's profound tissue hypoxia.
4
Notify the supervising registered nurse (RN) and the rapid response team.
Advanced medical support is initiated.
The client requires critical care interventions beyond the practical nursing scope. Escalation must occur immediately after the initial, scope-appropriate physical life-saving measures are secured.
5
Obtain a complete set of vital signs while remaining with the client.
Hemodynamic status is quantified.
Provides essential baseline data for the arriving rapid response team and helps monitor the client for impending cardiogenic shock.

Question 178Question →

A client in a preoperative holding area is preparing for an elective cholecystectomy. As the practical nurse (PN) presents the informed consent document for a signature, the client puts the pen down and states, "I changed my mind. I am too scared and I do not want this surgery anymore." In which order should the PN take the following actions? (Arrange the actions from first to last.)

Show answer & explanation

Answer

The correct sequence is to first remove the document to protect the client's right to refuse, then explore their fears to gather data, notify the surgeon who is legally responsible for discussing risks/alternatives, and finally document the event.
The nursing process and prioritization principles dictate that the PN must first address immediate safety and client rights (stopping the consent process). Next, the PN collects data (exploring fears) to inform the next intervention. The intervention is to communicate outside the PN's scope (notifying the surgeon to explain risks/alternatives). Finally, the PN documents the entire sequence of events to maintain legal records.

Step-by-Step Solution

1
Halt the consent process by removing the form.
The client is protected from signing under duress or uncertainty.
The PN's primary role in consent is verifying it is voluntary; if the client hesitates, the process must stop immediately.
2
Use therapeutic communication to assess the client's fears.
The PN gathers relevant subjective data about why the client is refusing.
Data collection is within the PN scope and provides necessary context before contacting the provider.
3
Contact the surgeon performing the procedure.
The provider is informed that consent has not been obtained.
Answering medical questions, explaining the risks of refusal, and providing alternatives fall exclusively under the provider's scope of practice.
4
Document the incident in the electronic health record.
A legal record of the client's refusal and the nursing actions is created.
Documentation is the final step in the nursing process after immediate interventions and communications are complete.

Key Concept

The practical nurse's role in informed consent is limited to witnessing the signature and verifying it is voluntary. If a client revokes consent, the PN must stop the process, gather data, and notify the provider.
Question 179Question →

A client who experienced a recent cerebrovascular accident has unilateral weakness. The nurse is assisting the client out of bed into a wheelchair for the first time. In which order should the nurse execute the following steps to safely perform a stand-and-pivot transfer? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence ensures safety by preparing the environment, securing the client, and executing the pivot on the client's strong side.
Following this precise chronological sequence minimizes the risk of falls and injury. The nurse must first establish environmental safety (positioning the chair on the strong side and locking wheels) before physically moving the client. Once the environment is secure, the nurse assists the client to sit, applies a safety device (transfer belt), and provides physical support (bracing the weak knee) before finally initiating the pivot maneuver.

Step-by-Step Solution

1
Position the wheelchair at a 45-degree angle on the client's unaffected side.
The destination equipment is properly positioned.
Setting up the environment first ensures the client can pivot toward their strong side with the shortest possible transfer distance.
2
Engage the wheel locks on both the bed and the wheelchair.
The bed and wheelchair are completely immobilized.
Immobilizing the equipment is a mandatory safety check to prevent the chair or bed from sliding away during the weight transfer.
3
Assist the client to sit on the edge of the bed and secure a transfer belt around their waist.
The client is sitting upright and equipped with a safety device.
Dangling allows the nurse to assess the client for orthostatic hypotension and dizziness, while the belt provides a secure hold for lifting.
4
Stand facing the client, grasp the transfer belt, and brace the client's weakened knee with your own knee.
Physical support and leverage are established.
Bracing the affected knee prevents it from buckling under the client's weight during the standing phase of the transfer.
5
Instruct the client to bear weight on the strong leg while pivoting to reach back for the wheelchair armrests.
The client safely transitions from a standing position into the wheelchair.
Reaching back provides a physical target and helps the client control their descent into the chair without falling.

A client with a history of epilepsy suddenly begins to experience a generalized tonic-clonic seizure while sitting in a bedside chair. To prevent injury, in what order should the practical nurse perform the following actions? (Arrange the actions from first to last.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a client having a seizure in a chair is to first safely guide them to the floor, protect their head, turn them on their side to protect the airway, loosen restrictive clothing, and finally note the time and duration.
During a generalized tonic-clonic seizure, the nurse's primary goal is to prevent physical injury and maintain a patent airway. The nurse must first safely lower the client to the floor to prevent a traumatic fall from the chair. Next, the head must be protected from striking the floor. The client is then rolled onto their side to allow saliva or emesis to drain, preventing aspiration. Loosening tight clothing further supports respiratory function. Once the client is physically secure and breathing safely, the nurse notes the exact time to monitor the seizure's duration and document the clinical event.

Step-by-Step Solution

1
Guide the client safely to the floor.
The client is placed on a flat, secure surface.
The client is unsafe in a chair and at immediate risk of an uncontrolled, traumatic fall.
2
Protect the client's head with a soft pad.
The head is cushioned against the floor.
Active convulsions against a hard floor can cause severe head injury and contusions.
3
Turn the client onto a lateral (side-lying) position.
The airway is cleared of potential obstruction.
Lateral positioning allows saliva and emesis to drain freely, preventing aspiration pneumonia and maintaining respiratory function.
4
Loosen restrictive clothing around the neck and chest.
Breathing effort is facilitated.
Tight clothing can restrict airflow and compromise oxygenation during a neurologic emergency.
5
Note the onset time and observe the duration.
Accurate clinical data is gathered.
Documentation and timing are essential for medical follow-up but are secondary to immediate physical safety.
