Upon arriving for a shift on a medical-surgical unit, a practical nurse reviews the shift roster and discovers they have been assigned a client who is hemodynamically unstable and requires continuous titration of intravenous vasoactive medications. Arrange the actions the practical nurse should take in the correct chronological order to safely manage this assignment conflict.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions is: 1) Identify that the assignment exceeds the scope of practice, 2) Verbalize the concern to the charge nurse, 3) Collaborate to reassign the unstable client, and 4) Accept a modified, safe assignment.
A practical nurse is legally responsible for accepting only those assignments that align with their educational preparation, experience, and the state's Nurse Practice Act. When presented with an unsafe or out-of-scope assignment, the nurse must first recognize the limitation, then follow the chain of command by notifying the charge nurse immediately. Resolving the issue collaboratively ensures the unstable client receives appropriate care from a registered nurse, allowing the practical nurse to accept a modified, safe assignment and provide competent care.

Step-by-Step Solution

1
Analyze the assignment against the legal scope of practice.
The nurse determines that an unstable client needing continuous IV vasoactive medications requires registered nurse (RN) level assessment and intervention.
Nurses are legally obligated to refuse tasks or assignments that fall outside their licensure or competency.
2
Initiate the chain of command.
The nurse informs the charge nurse about the specific limitation and safety risk.
Communication with the assigner must happen immediately so alternative arrangements can be made before care is delayed.
3
Engage in collaborative problem-solving.
The unstable client is reallocated to an RN's assignment.
Client safety is the priority, requiring appropriate distribution of unit resources based on acuity.
4
Assume responsibility for a safe assignment.
The practical nurse takes on an assignment of stable clients.
Once the assignment aligns with the practical nurse's scope and abilities, care can safely commence.

A practical nurse is preparing to provide nasotracheal suctioning for an infant infected with respiratory syncytial virus (RSV). Based on the precautions required for this pathogen and procedure, arrange the personal protective equipment (PPE) donning 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 for donning the required PPE is: Hand hygiene, Gown, Mask, Eyewear, and finally Gloves.
According to standard infection control guidelines, the proper chronological sequence for donning personal protective equipment begins with hand hygiene to prevent contamination. Next, the isolation gown is applied as it covers the torso and clothing. Then, the respiratory protection (such as a surgical mask) is secured, followed by eye protection (goggles or a face shield) which rests over the mask. Finally, gloves are put on last so their cuffs can securely stretch over and cover the sleeves of the isolation gown.

Step-by-Step Solution

1
Identify the required transmission-based precautions for the scenario.
RSV requires Contact and Droplet precautions; the procedure (nasotracheal suctioning) adds a high risk of body fluid splashing.
Determines the full set of protective equipment needed (gown, mask, eyewear, and gloves).
2
Apply the standardized sequence for donning PPE.
The established sequence is: Hand hygiene -> Gown -> Mask -> Eyewear -> Gloves.
Following the correct chronological order prevents self-contamination and ensures proper barrier overlapping, such as gloves securing the gown cuffs.

A practical nurse is preparing to provide oral hygiene to a client who is comatose following a traumatic brain injury. Arrange the following actions in the order the nurse should perform them to ensure client safety and comfort. All options must be used.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the client laterally, then place the towel and basin, insert the padded tongue blade, cleanse the mouth while suctioning, and finally apply lip lubricant.
When providing oral hygiene to an unconscious or comatose client, the greatest risk is aspiration of fluids or secretions into the lungs because the client lacks an intact swallowing and gag reflex. Therefore, the nurse must first turn the client to a lateral (side-lying) position so that fluids naturally drain out of the mouth. Once the airway is protected, the nurse prepares the area with a towel and basin. A padded tongue blade is then used to safely keep the mouth open without risking injury. The nurse cleans the mouth while immediately suctioning any fluids to further prevent aspiration. Finally, water-soluble lubricant is applied to protect the lips from drying and cracking.

Step-by-Step Solution

1
Determine the highest priority action based on the client's neurological status.
Positioning the client in a lateral (side-lying) position is identified as the first and most critical step.
A comatose client lacks an intact gag reflex. Airway protection is the absolute priority; the lateral position allows fluids to drain out of the mouth by gravity, preventing aspiration.
2
Identify the preparatory steps for the procedure.
Placing a towel and emesis basin is identified as the second step.
After the client is in a safe position, the nurse protects the client's gown and bed linens from secretions and cleaning solutions.
3
Determine the safest method to access the oral cavity.
Inserting a padded tongue blade is selected as the third step.
Unconscious clients may reflexively bite down. The nurse must never insert fingers into the client's mouth. A padded tongue blade safely keeps the mouth open for cleaning.
4
Sequence the core intervention of oral care.
Cleansing the oral cavity while actively suctioning is identified as the fourth step.
Once the mouth is safely open, the nurse cleans the teeth and gums. Continuous or frequent suctioning is required to remove introduced fluids and loosened secretions.
5
Identify the final comfort measure.
Applying a water-soluble lubricant to the lips is the final step.
After the oral cavity is cleaned and secretions are removed, applying lubricant prevents drying, cracking, and potential tissue breakdown of the lips.

A practical nurse (PN) has finished providing wound care for a client on Contact and Airborne precautions for a methicillin-resistant Staphylococcus aureus (MRSA) infection and active tuberculosis. The PN is wearing an N95 respirator, a face shield, an isolation gown, and gloves. In what order should the PN safely remove the personal protective equipment (PPE)? Arrange the actions in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for doffing PPE is to first remove the gloves, then the face shield, followed by the isolation gown. After these items are removed, the nurse must exit the room and close the door before finally removing the N95 respirator.
According to standardized CDC guidelines for doffing personal protective equipment (PPE), the most contaminated items must be removed first to prevent cross-contamination. Gloves are removed first, followed by the face shield or goggles (handled by the clean ear pieces or headbands). Next, the isolation gown is removed by unfastening the ties and rolling it inside out. When Airborne Precautions are in place, the nurse must then exit the isolation room and close the door before safely removing the N95 respirator in the hallway or anteroom.

Step-by-Step Solution

1
Identify and remove the most contaminated piece of equipment first.
The gloves are removed and discarded in the appropriate receptacle.
This prevents the transfer of pathogens from the hands to the face or hair during the removal of other PPE.
2
Remove face and eye protection.
The face shield is removed by handling only the clean headbands or ear pieces.
The front of the face shield is considered contaminated; handling only the back straps prevents hand contamination.
3
Remove the remaining body coverage.
The isolation gown is unfastened and rolled inside out into a bundle.
Rolling the gown inside out contains the MRSA pathogens present on the front and sleeves.
4
Maintain airborne protection while in the infectious environment.
The nurse exits the room and ensures the door is closed.
The N95 respirator must remain on while inside the airborne infection isolation room to filter aerosolized tuberculosis bacteria.
5
Remove respiratory protection in a safe area.
The N95 respirator is removed strictly outside the room and discarded.
This ensures the nurse is in a clean environment before exposing their respiratory tract to ambient air.

A practical nurse is preparing to transfer a client who has left-sided hemiparesis following a cerebrovascular accident from the bed to a wheelchair. In what order should the nurse perform the following actions? (Move the steps into the correct chronological order.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Position the wheelchair on the right side and lock wheels, assist to a sitting position on the edge of the bed, secure the transfer belt, brace the left knee, and finally assist to stand and pivot on the right leg.
Safe transfer of a client with hemiparesis requires strict adherence to biomechanical principles. The environment must be prepared first by placing the wheelchair on the strong (right) side to ensure the client pivots toward their strength. The client is then brought to a sitting position to stabilize blood pressure. A transfer belt is applied next for a secure hold. Before standing, the nurse must brace the weak (left) knee to prevent it from collapsing. Finally, the client uses their strong side to pivot and stabilize themselves in the wheelchair.

Step-by-Step Solution

1
Determine the client's strong and weak sides based on the diagnosis of left-sided hemiparesis.
The left side is weak, and the right side is strong.
Transfers must always be initiated toward the client's strong side for safety and stability.
2
Place the equipment (wheelchair) in the optimal position.
The wheelchair is placed on the right side at a 45-degree angle and locked.
Equipment must be ready and secure before moving the client.
3
Prepare the client physically for the transfer.
The client is assisted to a dangling position with feet flat, and the transfer belt is applied.
Dangling prevents orthostatic hypotension, and flat feet provide a solid base. The belt ensures a safe grip for the nurse.
4
Position yourself to protect the client's weak extremities.
The nurse faces the client and braces the left knee.
Hemiparetic extremities can buckle easily under weight; bracing provides external support.
5
Execute the pivot transfer.
The client pivots on the strong right leg and reaches with the strong right hand.
Pivoting on the strong side allows the client to bear their own weight safely and control their descent into the chair.

A practical nurse (PN) is providing morning care to a client who is 3 days postoperative following an exploratory laparotomy. The client coughs forcefully and reports a "popping" sensation. The PN observes that the abdominal incision has completely separated, with a loop of bowel protruding. Arrange the following nursing 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 priority sequence is to first call for assistance while staying with the client, then position the client to reduce abdominal tension, cover the exposed organs with moist sterile dressings, obtain vital signs to assess for shock, and finally prepare the client for emergency surgery.
Wound evisceration is an acute medical emergency requiring immediate, stepwise intervention. First, the nurse must call for help while remaining at the bedside to ensure safety and escalate care. Second, placing the client in a low Fowler's position with knees flexed minimizes intra-abdominal pressure and halts further organ protrusion. Third, applying sterile, saline-soaked dressings protects the exposed bowel from ischemia and necrosis. Fourth, monitoring vital signs assesses the client for hemodynamic instability and shock. Finally, ensuring NPO status and preparing the client for surgery addresses the definitive medical treatment.

Step-by-Step Solution

1
Call for immediate assistance while remaining with the client.
Help is summoned without abandoning the unstable client.
Evisceration is a life-threatening surgical emergency requiring a provider and an operating room. The PN must stay with the client to prevent further injury while help is dispatched.
2
Position the client in a low Fowler's position with the knees flexed.
Abdominal muscle tension is minimized.
This specific position relieves pressure on the abdominal cavity, physically preventing further protrusion of the intestines.
3
Cover the protruding bowel with sterile dressings moistened with sterile normal saline.
The exposed bowel is protected from drying and infection.
Exposed internal organs can quickly become ischemic or necrotic if allowed to dry out. A moist, sterile environment preserves tissue viability.
4
Obtain a complete set of vital signs to monitor for signs of shock.
Baseline hemodynamic status is established during the emergency.
The client is at high risk for hypovolemic shock due to fluid shifts and trauma. Vital signs dictate further circulatory interventions.
5
Ensure the client is on strict nothing by mouth (NPO) status and prepare for emergency surgery.
The client is readied for surgical repair.
The definitive treatment for an evisceration is surgical closure. Ensuring NPO status prevents aspiration during the impending administration of anesthesia.

Key Concept

The priority management of an abdominal wound evisceration focuses on immediately securing help, minimizing intra-abdominal pressure, and preserving the viability of the exposed organs without leaving the bedside.
Question 47Question →

A practical nurse (PN) is preparing to administer morning medications, including digoxin and furosemide. When checking the client's chart, the PN discovers a new serum potassium result of 2.62.6 mEq/L. Arrange the following actions in the correct priority sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first withhold the medications, then assess the client's apical pulse, report the findings to the registered nurse, and finally document the actions taken.
When a practical nurse identifies a critical laboratory value such as a potassium level of 2.62.6 mEq/L, the immediate priority is client safety. The PN must first withhold any medications that could exacerbate the condition, such as furosemide (which wastes potassium) and digoxin (which becomes highly toxic in hypokalemia). Next, the PN must assess the client for active complications, specifically checking the apical pulse for arrhythmias. Once the assessment data is collected, the PN reports a complete clinical picture to the RN to facilitate prompt medical intervention. Finally, all findings and actions are thoroughly documented in the electronic health record.

Step-by-Step Solution

1
Withhold the administration of the scheduled digoxin and furosemide.
Further depletion of potassium and potential digoxin toxicity are prevented.
Safety is the initial priority. Furosemide actively depletes potassium, and hypokalemia severely increases the risk of life-threatening digoxin toxicity.
2
Assess the client's apical pulse and observe for signs of profound muscle weakness.
Current clinical data regarding the client's physiological response to hypokalemia is obtained.
The PN must determine if the critical lab value is actively causing adverse effects, such as cardiac arrhythmias, before notifying the healthcare team.
3
Report the critical potassium level and the client's vital signs to the supervising registered nurse.
The registered nurse and healthcare provider are alerted to the emergency.
Escalation is required so the provider can prescribe corrective treatments, such as potassium replacement therapy.
4
Document the withheld medications, assessment findings, and the RN notification in the health record.
A clear, legal record of the clinical event and nursing interventions is created.
Documentation should occur after the client is stabilized and the healthcare team has been notified of the critical findings.

The nurse anticipates contact with copious respiratory secretions. Arrange the following steps for donning the required personal protective equipment (PPE) in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for donning PPE is: 1. Perform hand hygiene, 2. Put on the isolation gown, 3. Apply a surgical mask, 4. Place goggles or a face shield, 5. Don clean gloves.
The Centers for Disease Control and Prevention (CDC) guidelines mandate a specific sequence for donning PPE to maximize protection and prevent contamination. Hand hygiene is always the required first step. The gown is applied first as it is the largest barrier and requires reaching behind the neck and waist. The mask is applied second to secure respiratory protection. Eye protection is added third, resting over the upper edge of the mask. Gloves are applied last so they can be extended over the gown cuffs to seal the wrist area.

Step-by-Step Solution

1
Perform hand hygiene.
Hands are clean before touching PPE.
Prevents the transfer of pathogens to the clean protective equipment.
2
Don the isolation gown.
The torso and arms are protected.
The gown is the bulkiest item and requires tying at the back, which should be done before hand dexterity is reduced by gloves.
3
Apply the surgical mask.
The nose and mouth are protected from droplet splashes.
The mask must be fitted properly to the face before eye protection is added.
4
Place goggles or a face shield.
The eyes are protected from potential secretion splashes.
Eye protection rests over the mask to ensure complete coverage without compromising the mask's fit.
5
Don clean gloves.
The hands and wrists are fully protected.
Pulling gloves over the gown cuffs ensures there is no exposed skin at the wrists.

Question 49Question →

An unresponsive client requires oral hygiene to maintain mucosal integrity. In which order should the practical nurse perform the following actions to complete this procedure safely? Arrange the steps in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the client side-lying, place protective linens and a basin, safely open the mouth with a padded tongue blade, perform the cleaning with simultaneous suctioning, and finally moisturize the lips.
When providing oral hygiene to an unresponsive client, safety—specifically airway protection—is the absolute highest priority. Therefore, the client must first be turned to a side-lying position to utilize gravity for drainage. Once positioned safely, the nurse prepares the area with a towel and basin to maintain cleanliness. Next, safe access to the oral cavity is secured using a padded tongue blade, preventing injury from reflex biting. The actual cleaning is then performed simultaneously with suctioning to ensure no fluid accumulates in the airway. Finally, the procedure concludes with a comfort measure, applying water-soluble lubricant to prevent the lips from drying and cracking.

Step-by-Step Solution

1
Assist the client into a side-lying position.
The client is in a safe posture for oral care.
The side-lying position allows fluids to pool in the side of the mouth and drain out, significantly reducing the risk of aspiration.
2
Place a towel under the client's chin and an emesis basin against the cheek.
The physical environment is prepared.
This step protects the client's gown and linens from becoming soiled and provides a receptacle for the oral drainage.
3
Insert a padded tongue blade gently between the back molars to open the mouth.
The oral cavity is safely accessed.
An unresponsive client may bite down reflexively. Using a padded tongue blade protects both the client's teeth and the nurse's fingers.
4
Clean the teeth and oral mucosa using a moistened swab while applying suction.
The mouth is cleaned and secretions are removed.
Cleaning removes plaque and bacteria. Continuous or intermittent suctioning ensures that the fluid used for cleaning and any loosened secretions are not aspirated into the lungs.
5
Apply a water-soluble lubricant to the client's lips.
The client's lips are protected from cracking.
Unresponsive clients often breathe through their mouths, leading to dry lips. A water-soluble lubricant maintains tissue integrity without the flammability risk associated with petroleum-based products.

A practical nurse enters the room of a client who has a central venous catheter. The nurse discovers that the intravenous tubing has disconnected from the catheter hub. The client suddenly reports sharp chest pain, is gasping for air, and appears cyanotic. In what order should the nurse perform the following actions to reduce the client's risk of further harm? Arrange the steps in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for managing a suspected central line air embolism is to first clamp the catheter to stop air entry, then position the client in a left lateral Trendelenburg position to trap the air, followed by administering high-flow oxygen, activating the Rapid Response Team, and finally obtaining vital signs.
The sequence reflects the fundamental principles of risk reduction during an acute central line complication: stop the source of the injury (clamp), mitigate the immediate pathophysiological risk (position to trap air), treat the physiological symptoms (oxygen), escalate care (call for help), and evaluate the client's status (vital signs).

Step-by-Step Solution

1
Clamp the disconnected central venous catheter.
Stops further air from entering the circulatory system.
The most critical initial action in any mechanical hazard is to eliminate the source of the harm before addressing the consequences.
2
Place the client in a left lateral Trendelenburg position.
Traps the air embolus in the right ventricle.
This specific gravitational positioning prevents the air bubble from moving forward into the pulmonary circulation, which would cause an acute right ventricular outflow obstruction.
3
Administer high-flow oxygen.
Treats systemic hypoxia and reduces the size of the embolus.
Administering 100% oxygen addresses the respiratory distress and creates a diffusion gradient that helps the body resorb the nitrogen-rich air bubble.
4
Activate the Rapid Response Team.
Summons advanced medical and critical care support.
An air embolism is a profound systemic emergency requiring interventions and continuous monitoring beyond the practical nurse's scope of practice.
5
Obtain vital signs.
Establishes a baseline of the client's current physiological status.
Vital signs provide essential, objective data regarding cardiac output and respiratory effort for the Rapid Response Team upon their arrival.

Key Concept

Prioritization of interventions for a central venous catheter air embolism requires stopping the source of air first, followed by mechanical positioning to trap the air, and then supportive oxygen therapy.

A practical nurse is preparing to collect a sterile urine specimen for culture and sensitivity from a client's indwelling urinary catheter. To reduce the risk of sample contamination and client infection, in what order should the nurse perform the following actions? (Arrange the steps in the correct sequence from first to last.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first clamp the tubing to collect urine, clean the port, withdraw the sample with a syringe, transfer it to a sterile cup, and finally unclamp the tubing.
The collection of a sterile urine specimen from a closed urinary drainage system requires strict aseptic technique to prevent introducing bacteria into the client's bladder and to ensure the laboratory results are accurate. First, the tubing is clamped to collect freshly produced urine. Next, the port must be disinfected before access. A sterile syringe is then used to withdraw the sample from the clean port. The sample is transferred to a sterile cup, and finally, the tubing must be unclamped to prevent urinary retention and potential kidney damage from backflow.

Step-by-Step Solution

1
Clamp the drainage tubing.
Fresh urine collects above the clamp.
Urine from the drainage bag is not sterile; fresh urine must be collected to ensure an accurate culture.
2
Scrub the aspiration port.
The surface of the port is disinfected.
Prevents the introduction of surface pathogens into the urinary tract when the syringe is attached.
3
Aspirate the urine.
A sterile sample is obtained.
Safely extracts the accumulated urine using a closed-system approach.
4
Transfer the sample.
The urine is secured in a sterile container.
Prepares the specimen for transport to the laboratory without environmental contamination.
5
Remove the clamp.
Continuous bladder drainage is restored.
Prevents urinary retention, bladder spasms, and potential kidney damage from urine backflow.

A practical nurse (PN) is preparing to administer prescribed timolol eye drops to a client diagnosed with glaucoma. Assuming hand hygiene has been performed and clean gloves are applied, in what order should the PN perform the following steps?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first cleanse the eye, position the client looking upward, expose the conjunctival sac, instill the medication into the sac, and finally apply pressure to the nasolacrimal duct.
The proper sequence for ophthalmic administration prioritizes infection control, client safety, and the prevention of systemic absorption. Cleansing the eye first prevents the introduction of debris. Proper positioning and exposing the conjunctival sac protect the highly sensitive cornea from injury. Instilling the medication into the sac ensures even distribution. Finally, applying pressure to the nasolacrimal duct is a critical safety step to prevent systemic effects of the medication.

Step-by-Step Solution

1
Cleanse the client's eyelid and eyelashes, wiping from the inner to the outer canthus.
Debris is removed from the eye area.
Prevents the introduction of external contaminants into the eye during administration.
2
Instruct the client to tilt their head back slightly and look up at the ceiling.
The cornea is rotated upward and away.
Reduces the risk of stimulating the blink reflex and protects the cornea from injury.
3
Gently pull down the client's lower eyelid using a thumb or index finger to expose the conjunctival sac.
The conjunctival sac is exposed.
Creates a pouch to safely receive the medication without dropping it directly onto the sensitive cornea.
4
Instill the prescribed number of drops into the center of the lower conjunctival sac.
Medication is delivered evenly without touching the eye.
Prevents injury to the cornea and maintains the sterility of the medication dropper.
5
Apply gentle pressure to the client's nasolacrimal duct for 30 to 60 seconds.
The nasolacrimal duct is occluded.
Prevents systemic absorption of the medication, which is critical when administering beta-blockers like timolol.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

First, place the client in a supine position. Second, turn the stocking inside out to the heel. Third, apply the stocking over the toes and heel. Fourth, slide it up the calf. Finally, smooth out any wrinkles.
The correct sequence for applying anti-embolism stockings prioritizes promoting venous return and protecting skin integrity. The client must first be supine to allow blood to drain from the lower extremities. Preparing the stocking by turning it to the heel allows for smooth application over the foot, followed by pulling it up the calf. Finally, smoothing wrinkles prevents pressure injuries.

Step-by-Step Solution

1
Evaluate the client's position and timing before application.
The client is placed in a supine position for 15 to 30 minutes.
This prevents trapping dependent venous blood in the lower legs.
2
Prepare the stocking for application.
The stocking is inverted inside out down to the heel pocket.
This technique allows for controlled, precise placement over the foot without excessive pulling or friction.
3
Apply the stocking to the foot.
The stocking covers the toes and the heel pocket is correctly aligned.
Proper alignment of the heel pocket is crucial for comfort and correct compression distribution.
4
Apply the stocking to the lower leg.
The remainder of the stocking is slid up the calf.
This applies the graduated compression needed to promote venous return.
5
Inspect the applied stocking.
All wrinkles and creases are smoothed out.
Wrinkles act as a tourniquet, impeding venous return and potentially causing skin breakdown.

A practical nurse (PN) is preparing to administer an intramuscular injection of prescribed iron dextran to an adult client using the Z-track method. In what order should the PN perform the following steps to ensure safe administration? Arrange the actions in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first change the drawing-up needle, then retract the skin and subcutaneous tissue, insert the needle at a 90-degree angle, inject the medication while pausing for 10 seconds, and finally withdraw the needle while simultaneously releasing the skin.
The Z-track method requires strict adherence to a specific sequence to prevent tissue damage. First, a new needle must be attached to ensure the outside is free of irritating medication. Next, the skin is retracted to displace the tissue layers. The needle is then inserted at 90 degrees. After injecting slowly, a 10-second pause is necessary for medication dispersion. Finally, withdrawing the needle and releasing the skin simultaneously seals the track, trapping the medication in the muscle.

Step-by-Step Solution

1
Change the drawing-up needle to a new, sterile administration needle.
Ensures the exterior of the needle shaft is free of medication.
Iron dextran can cause permanent tissue staining and severe irritation if deposited in the subcutaneous layers during insertion.
2
Retract the skin and subcutaneous tissue 1 to 1.5 inches laterally.
Moves the superficial tissues out of alignment with the underlying muscle.
This is the core principle of the Z-track method, preparing the 'zigzag' path that will lock the medication in the muscle.
3
Insert the needle at a 90-degree angle.
Penetrates through the displaced tissue directly into the muscle belly.
A 90-degree angle is required for intramuscular injections to ensure the medication reaches deep muscle tissue.
4
Inject the medication slowly and maintain the needle's position for 10 seconds.
Deposits the medication and allows it to begin diffusing into the surrounding muscle fibers.
Slow injection minimizes discomfort, and the 10-second pause prevents the medication from immediately welling up the injection track.
5
Withdraw the needle and release the retracted skin simultaneously.
The tissue layers slide back into their original positions, breaking the needle track alignment.
This seals the track, effectively trapping the irritating medication deep within the muscle and preventing seepage to the surface.

Key Concept

The Z-track method for intramuscular injections is used to prevent highly irritating or staining medications from leaking back into the subcutaneous tissue by displacing tissue layers before injection.

A nurse has finished providing routine morning care for a client placed on droplet and contact precautions. The nurse is wearing a disposable isolation gown, clean gloves, a surgical mask, and a face shield. Arrange the steps for safely removing (doffing) the personal protective equipment (PPE) in the correct sequential order to minimize the risk of self-contamination.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for removing PPE is: 1) Gloves, 2) Face shield, 3) Gown, 4) Surgical mask, and 5) Hand hygiene.
According to the Centers for Disease Control and Prevention (CDC) guidelines, the safest standard sequence for removing PPE individually is to remove gloves first, followed by the face shield or goggles, then the gown, and finally the mask or respirator, concluding with thorough hand hygiene. This specific order ensures that the most heavily contaminated items (gloves and gown front) are removed in a way that minimizes the risk of transferring pathogens to the nurse's face, mucous membranes, or clean uniform.

Step-by-Step Solution

1
Determine the most contaminated item of PPE to remove first.
Gloves are identified as the most heavily contaminated item from direct patient and environmental contact and are removed first.
Removing the most contaminated item initially minimizes the immediate risk of cross-contamination to the nurse's face, hair, and uniform during subsequent steps.
2
Identify the next item to remove that protects the face but can be handled by clean straps.
The face shield is removed next by handling only the clean earpieces or headband at the back of the head.
This protects the mucous membranes of the eyes and is safely removed before the gown to prevent contaminated gown particles from reaching the face.
3
Remove the core body protection.
The gown is unfastened, pulled away from the neck and shoulders, and rolled inside out.
Rolling the gown inside out traps the surface contaminants within the bundle, preventing them from brushing against the nurse's clean uniform.
4
Remove the respiratory protection.
The surgical mask is removed by untying the bottom strings, followed by the top strings, touching only the ties.
The mask is kept on until the end to protect the respiratory tract from any aerosolized particles that might be generated while taking off the gown and other PPE.
5
Perform the final essential infection control measure.
Hand hygiene is performed immediately after all PPE is discarded.
This step ensures that any pathogens accidentally transferred to the hands during the doffing procedure are eliminated before the nurse exits the area or touches anything else.

Key Concept

The correct sequential removal (doffing) of Personal Protective Equipment (PPE) is designed to prevent self-contamination and the spread of pathogens. The standard individual removal order is Gloves, Goggles/Face Shield, Gown, Mask, and finally Hand Hygiene.

Safe application of a transdermal patch requires a systematic approach to protect both the nurse and the client. First, the nurse must don gloves to avoid self-absorption of the vasoactive medication. Second, the old patch must be removed to prevent an accidental overdose. Third, the new site is cleaned with water to promote adherence. Fourth, the patch is labeled before application to prevent pressing too hard on the client's skin. Finally, it is applied to a new, hairless area to prevent contact dermatitis and ensure consistent medication absorption.

Step-by-Step Solution

1
Perform hand hygiene and put on clean gloves.
Prevents nurse exposure.
Nitroglycerin can be easily absorbed through the nurse's skin, potentially causing a severe headache or hypotension.
2
Remove the previous patch and fold it in half with the adhesive sides together.
Discards old medication safely.
Leaving the old patch on while applying a new one can cause a dangerous medication overdose.
3
Cleanse the new application site with water and allow it to dry completely.
Prepares a clean surface.
Ensures the new patch adheres properly and absorbs at a predictable, steady rate.
4
Write the date, time, and initials on the outside of the new patch.
Documents the administration.
Facilitates tracking for the next nurse and avoids pressing a writing instrument into the client's tissue.
5
Apply the new patch to a rotated, hairless area of intact skin.
Administers the medication.
Site rotation minimizes local skin irritation and maintains optimal skin integrity for future applications.

Key Concept

Safe administration of transdermal medications involves protecting the nurse with gloves, preventing overdose by removing old patches first, and ensuring proper site preparation for consistent systemic absorption.

A practical nurse has completed providing care for a client placed on airborne and contact precautions due to disseminated herpes zoster. The nurse is currently wearing an N95 respirator, an isolation gown, and gloves. In what order should the nurse perform the following actions to safely remove the personal protective equipment (PPE)? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for doffing PPE in this scenario is: remove gloves, remove gown, perform hand hygiene and exit the room, remove the N95 respirator outside the room, and perform a final hand hygiene.
The Centers for Disease Control and Prevention (CDC) guidelines for removing PPE require the most contaminated items to be removed first. Gloves are removed initially, followed by the gown. Because the client requires airborne precautions, the N95 respirator must remain on until the nurse has exited the room and closed the door. Hand hygiene is essential both before exiting the room (to avoid contaminating the door handle) and after removing the respirator.

Step-by-Step Solution

1
Remove gloves
Gloves are safely discarded in the room.
Gloves are the most contaminated item and are removed first to prevent transfer of pathogens to the body or environment.
2
Remove the isolation gown
Gown is rolled inside out and discarded in the room.
The front and sleeves of the gown are contaminated. Removing it inside the room prevents spreading contact pathogens into the hallway.
3
Perform hand hygiene and exit the room
Hands are clean before touching the door.
This prevents contaminating the doorknob and the environment outside the isolation room.
4
Remove the N95 respirator outside the room
Respirator is safely removed and discarded.
Airborne pathogens can remain suspended in the air. The respirator must stay in place until the nurse is completely outside the contaminated airspace.
5
Perform final hand hygiene
Hands are completely sanitized.
Touching the straps of the respirator during removal may transfer small amounts of pathogens to the hands.

A practical nurse (PN) is inserting a nasogastric (NG) tube for a client with a bowel obstruction. To reduce the risk of respiratory trauma and aspiration, 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 for safe nasogastric tube insertion is to first measure the required tube length, then hyperextend the client's neck for initial nasal insertion, flex the chin to the chest once the tube reaches the throat, advance the tube while the client swallows, and finally verify placement by aspirating and testing the pH.
The correct sequence ensures client safety by aligning the airway anatomy appropriately at each stage of the procedure. Measurement must occur first to identify the target depth. The head is tilted back initially only to facilitate nasal entry. Crucially, the head must be tilted forward (chin-to-chest) when the tube reaches the back of the throat to close the trachea. Swallowing assists esophageal passage, and verifying placement via pH is the final bedside safety check before utilizing the tube.

Step-by-Step Solution

1
Determine the proper insertion depth.
The PN measures from the nose to the earlobe down to the xiphoid process.
This establishes a reliable landmark to ensure the tube reaches the stomach without coiling in the esophagus.
2
Navigate the nasal cavity.
The client hyperextends their neck while the PN advances the tube.
Tilting the head back straightens the nasal passage, minimizing mucosal trauma during initial entry.
3
Protect the airway at the oropharynx.
The client flexes their chin toward their chest.
This anatomical shift forces the epiglottis to cover the glottis, which is vital for preventing the tube from entering the trachea.
4
Pass the tube down the esophagus.
The client swallows water as the PN advances the tube.
Swallowing initiates peristalsis and keeps the airway closed, facilitating a smooth and safe passage into the stomach.
5
Verify initial placement.
The PN aspirates contents and checks the pH.
Testing the pH of the aspirate confirms acidic gastric placement, immediately reducing the risk of inadvertently administering fluids into the lungs.

Key Concept

Correct anatomical positioning—specifically transitioning from neck hyperextension to chin-to-chest flexion—during nasogastric tube insertion is a critical maneuver to close the airway and prevent accidental tracheal intubation.

A practical nurse is preparing to transfer a client who has left-sided weakness from the bed to a wheelchair. In what order should the nurse perform the following actions? Arrange the steps in the correct sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: position the wheelchair on the strong side, lock the brakes, assist the client to a sitting position, apply the transfer belt, and finally assist the client to stand and pivot.
The correct sequence prioritizes environmental preparation, equipment safety, client physiological readiness, the application of safety devices, and finally, the execution of the transfer using proper body mechanics.

Step-by-Step Solution

1
Position the wheelchair on the client's strong side (right side) at a 45-degree angle.
The wheelchair is optimally aligned for the safest possible transfer.
Transferring toward the strong side allows the client to bear weight and use their unaffected limbs for support during the pivot.
2
Lock the brakes on the bed and wheelchair.
Both surfaces are completely immobilized.
This prevents the equipment from sliding away during the weight shift, significantly reducing the risk of a fall.
3
Assist the client to sit on the edge of the bed with their feet flat on the floor.
The client is upright and stabilized with a solid base of support.
Dangling allows the body to adjust to the position change, preventing dizziness from orthostatic hypotension before standing.
4
Apply a transfer belt snugly around the client's waist.
The nurse has a secure, mechanical grip point.
A gait belt decreases the risk of dropping the client and prevents injury to the nurse's back or the client's limbs by avoiding lifting under the arms.
5
Brace the weak leg, assist the client to stand, and pivot.
The client is safely moved from the bed into the wheelchair.
Bracing the hemiparetic left leg prevents the knee from collapsing under the client's body weight, ensuring a controlled descent into the chair.

A practical nurse (PN) is preparing to administer a combined dose of regular insulin and NPH insulin in a single syringe to a client with type 2 diabetes mellitus. Arrange the following steps for preparing this medication in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to 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.
The correct sequence for mixing insulins ensures precise dosing and prevents contamination of the vials. The PN must first gently roll the NPH (cloudy) insulin to resuspend the particles. To prevent negative pressure, air is injected into the NPH vial first, followed by injecting air into the regular (clear) insulin vial. The regular insulin is drawn up immediately after injecting air into its vial (clear before cloudy). Finally, the NPH insulin is drawn up. This sequence prevents the intermediate-acting NPH insulin from accidentally entering and altering the pharmacokinetics of the rapid/short-acting regular insulin vial.

Step-by-Step Solution

1
Roll the NPH insulin vial gently between the palms.
The NPH insulin suspension is evenly mixed without creating air bubbles.
NPH insulin is a suspension that settles on standing and requires gentle mixing prior to use to ensure accurate dosing.
2
Inject air equal to the prescribed dose into the NPH insulin vial.
The NPH vial is pressurized.
Prevents negative pressure in the vial. Doing this first keeps the needle free of regular insulin, preventing contamination of the NPH vial.
3
Inject air equal to the prescribed dose into the regular insulin vial.
The regular insulin vial is pressurized and ready for withdrawal.
Prevents negative pressure. Because the needle is now in the regular insulin vial, withdrawal can begin immediately without removing the needle.
4
Withdraw the prescribed dose of regular insulin into the syringe.
Clear insulin is drawn into the syringe.
Regular (clear) insulin is always drawn up first. This prevents contamination of the rapid-acting insulin vial with the longer-acting NPH insulin.
5
Withdraw the prescribed dose of NPH insulin into the syringe.
The mixed dose is completed accurately.
NPH (cloudy) insulin is drawn last because introducing regular insulin into the NPH vial does not negatively alter the intermediate-acting insulin's properties.
