Question 201Question →

An adolescent client is brought to the emergency department exhibiting deep, rapid respirations, a fruity breath odor, and severe lethargy. The initial capillary blood glucose is 580 mg/dL580 \text{ mg/dL} (32.2 mmol/L32.2 \text{ mmol/L}). The healthcare provider diagnoses diabetic ketoacidosis (DKA). 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 prioritizes immediate life support followed by specific DKA management: first, assess airway patency and apply oxygen; second, establish large-bore IV access; third, administer a rapid IV infusion of 0.9%0.9\% sodium chloride; fourth, initiate a continuous IV infusion of regular insulin; and finally, monitor serum potassium levels and replace as prescribed.
The correct sequence follows the ABCs (Airway, Breathing, Circulation) of emergency resuscitation combined with the standard protocol for Diabetic Ketoacidosis (DKA). Airway protection and oxygenation are always the first priority for a lethargic client. Once the airway is secured, IV access must be established to provide a route for rapid emergency interventions. The immediate medical priority in DKA is aggressive fluid resuscitation with isotonic saline to reverse severe dehydration and prevent hypovolemic shock. Only after fluid resuscitation has begun should continuous IV regular insulin be initiated to correct the hyperglycemia and acidosis. Finally, because insulin drives potassium into the intracellular space, continuous monitoring and subsequent replacement of potassium are essential to prevent life-threatening dysrhythmias.

Step-by-Step Solution

1
Apply the ABCs (Airway, Breathing, Circulation) framework to prioritize immediate life-saving actions.
Assessing airway patency and applying oxygen is identified as the absolute first action.
Airway and oxygenation always take precedence in an emergency, especially in a patient with a compromised neurological status and altered respiratory patterns (Kussmaul respirations).
2
Identify the next most critical requirement for treating a client in severe metabolic distress.
Establishing large-bore IV access is prioritized next.
Without reliable intravenous access, life-saving fluids and medications cannot be administered to the client.
3
Determine the initial circulatory intervention for DKA.
Administering a rapid infusion of 0.9%0.9\% sodium chloride is the third action.
Severe dehydration and hypovolemia from osmotic diuresis must be corrected first to restore tissue perfusion and prevent vascular collapse.
4
Sequence the treatment for the underlying metabolic acidosis and hyperglycemia.
Initiating a continuous IV infusion of regular insulin is the fourth action.
Insulin halts ketone production and drives glucose into the cells, directly treating the pathophysiology of DKA, but it must only be given after fluid resuscitation has started.
5
Anticipate the complications of the medical interventions.
Monitoring and replacing potassium is the final action in this immediate sequence.
Intravenous insulin therapy drives potassium into the intracellular space, causing hypokalemia. This requires continuous monitoring and replacement once adequate urine output is confirmed.

Question 202Question →

A client with a history of aggressive behavior is pacing rapidly in the day room, clenching their fists, and muttering angrily to themselves. The nurse needs to intervene to prevent an escalation of violence. Arrange the following behavioral interventions in chronological order from the least restrictive to the most restrictive approach.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order from least to most restrictive is: Attempt verbal de-escalation, offer PRN oral medication, administer PRN intramuscular medication, and finally apply physical restraints.
The legal and ethical principle of the least restrictive alternative mandates that healthcare providers use the least invasive interventions necessary to safely manage a client's behavior. The proper progression always begins with verbal and environmental modifications, moves to voluntary pharmacological interventions (oral route), then involuntary or invasive pharmacological interventions (intramuscular route), and concludes with physical restraints or seclusion only as an absolute last resort.

Step-by-Step Solution

1
Assess the level of restriction of verbal de-escalation.
Identified as the least restrictive measure.
It relies on interpersonal communication and voluntary cooperation without limiting physical movement.
2
Compare oral versus intramuscular medications.
Oral medication is determined to be less restrictive than IM medication.
Oral administration is voluntary and non-invasive, while an intramuscular injection is invasive and often administered involuntarily during a psychiatric crisis.
3
Assess the level of restriction of physical restraints.
Identified as the most restrictive measure.
It physically limits the client's freedom of movement and requires strict legal, ethical, and institutional justification.

Question 203Question →

A nurse is removing a central venous access device (CVAD) from a client's right subclavian vein. During the procedure, the client suddenly gasps for air, becomes profoundly dyspneic, and exhibits perioral cyanosis. The client's blood pressure drops to 72/40 mm Hg, and a loud 'churning' murmur is auscultated over the precordium. Arrange the following emergency nursing interventions in the correct physiological sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first immediately seal the insertion site to prevent further air entry, then place the client in the left lateral Trendelenburg position to trap the embolus, followed by administering 100% oxygen to shrink the bubble, activating the rapid response team, and finally preparing for advanced interventions.
The correct sequence prioritizes immediate source control (sealing the site) to prevent further harm, followed immediately by anatomical positioning (left lateral Trendelenburg) to prevent the fatal migration of the air embolus into the pulmonary artery. Once the embolus is contained, high-flow oxygen is administered to treat hypoxemia and reduce the bubble's size. Finally, summoning advanced help and preparing for definitive diagnostic procedures completes the emergency response.

Step-by-Step Solution

1
Seal the insertion site with an occlusive dressing.
Prevents further air entrainment into the central venous circulation.
Halting the source of the embolus is the primary step in resolving the crisis and preventing a larger, fatal air volume.
2
Position the client in the left lateral Trendelenburg position.
Traps the air bubble in the non-dependent apex of the right ventricle.
Prevents fatal obstructive shock caused by the air embolus migrating into the pulmonary artery.
3
Administer 100% oxygen via a non-rebreather mask.
Reverses hypoxemia and facilitates nitrogen washout.
High-concentration oxygen creates a gradient that shrinks the nitrogen-rich air embolus.
4
Activate the rapid response team.
Mobilizes advanced critical care providers.
Advanced pharmacological and mechanical interventions will be required to stabilize the client's hemodynamic status.
5
Prepare for advanced diagnostic and therapeutic interventions.
Facilitates definitive medical treatment.
Echocardiography or direct needle aspiration of the air from the heart may be necessary if conservative measures fail.

A nurse is teaching a client who has a non-weight-bearing right leg fracture how to ascend stairs using axillary crutches. In what order should the nurse instruct the client to 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 for ascending stairs with axillary crutches is to establish a tripod position, transfer weight to the crutches, step up with the unaffected leg, shift weight to the unaffected leg, and finally bring the crutches and affected leg up.
When ascending stairs with crutches, the primary safety principle is 'up with the good'. The client must first establish balance in the tripod position. By transferring weight to the crutches, the client frees the strong, unaffected leg to step up. Once the strong leg is on the stair, the client shifts their weight onto it. This strong leg then powers the lifting of the body, allowing the client to safely bring the crutches and the affected, non-weight-bearing leg up to the same step without compromising balance or the injury.

Step-by-Step Solution

1
Establish the tripod base.
The client achieves balance and stability.
Safety requires a solid base of support before attempting vertical movement.
2
Unweight the strong leg.
The body is supported entirely by the upper body and crutches.
The unaffected leg must be free to step upward.
3
Step up with the unaffected leg.
The strong leg is positioned on the next stair tread.
The strong leg acts as the elevator, doing the physical work of lifting the body against gravity.
4
Transfer body weight upward.
The client's weight shifts onto the strong leg.
This unloads the crutches and prepares them for advancement.
5
Advance the crutches and the affected leg.
The client stands fully on the new step with all devices.
This completes the stepping cycle while maintaining non-weight-bearing status on the injured leg.

Question 205Question →

A nurse is preparing to administer a prescribed intravenous (IV) push analgesic to a client. The client has a single peripheral IV line currently infusing a continuous medication. The drug reference guide indicates that the continuous infusion is physically incompatible with the prescribed IV push analgesic. Arrange the following nursing actions in the correct sequence to safely administer the medication.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first pause the pump, clamp the primary tubing, administer a pre-flush, administer the medication, administer a slow post-flush, and finally unclamp and resume the pump.
When administering an IV push medication through a line with a physically incompatible continuous infusion, the primary goal is to prevent the two medications from mixing and precipitating. The nurse must first pause the continuous infusion, then clamp the primary tubing above the lowest injection port to prevent the subsequent flush and medication from traveling backward up the line. A pre-flush clears the incompatible medication from the space between the port and the client. The medication is then administered safely. The post-flush must be administered at the same slow rate as the medication because the flush pushes the remaining medication residing in the IV catheter into the vein; pushing it too quickly would result in rapid administration of the analgesic, risking speed shock. Finally, the tubing is unclamped and the continuous infusion is resumed.

Step-by-Step Solution

1
Pause the electronic infusion pump delivering the continuous medication.
Stops the flow of the incompatible continuous medication.
Prevents further introduction of the incompatible drug into the system during the push procedure, which is the foundational step for preventing precipitation.
2
Clamp the primary intravenous tubing immediately above the lowest injection port.
Isolates the lower portion of the IV line from the main fluid bag.
Fluid follows the path of least resistance. Clamping prevents the flush and IV push medication from flowing retrogradely up the primary tubing and mixing with the incompatible medication.
3
Scrub the injection port with an antiseptic swab and administer a 10 mL 0.9% sodium chloride flush.
Clears the IV line from the injection port to the vein.
Ensures no incompatible continuous medication remains in the physical path of the IV push medication.
4
Inject the prescribed intravenous push analgesic over the manufacturer-recommended time.
Delivers the active medication safely into the systemic circulation.
Administering over the recommended time prevents adverse reactions such as speed shock, severe hypotension, or respiratory depression.
5
Administer a second 10 mL 0.9% sodium chloride flush at the identical rate used for the analgesic.
Clears the analgesic completely from the IV catheter and extension set.
The fluid inside the catheter and extension tubing contains the active analgesic. Flushing rapidly would inadvertently 'slam' this remaining dose into the vein too fast.
6
Unclamp the primary intravenous tubing and resume the continuous electronic infusion.
Restores the continuous therapy.
Ensures the client continues to receive the baseline prescribed infusion without unnecessary interruption.

Key Concept

Management of physically incompatible intravenous medications via a single peripheral access line requires strict procedural isolation using clamping and precise flushing techniques.
Question 206Question →

A nurse is admitting a client with a history of alcohol use disorder who had their last alcoholic drink 6 hours ago. Arrange the following manifestations of alcohol withdrawal in the chronological order in which they typically appear, from earliest to latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: 1) Mild tremors, anxiety, and diaphoresis, 2) Visual, auditory, or tactile hallucinations with intact orientation, 3) Generalized tonic-clonic seizures, 4) Delirium tremens with severe agitation and autonomic hyperactivity.
Alcohol withdrawal progresses through a predictable clinical timeline based on the central nervous system's rebound hyperactivity. Mild withdrawal symptoms like tremors and diaphoresis are the earliest signs, emerging 6 to 12 hours after cessation. Alcoholic hallucinosis follows next (12 to 24 hours) where the client experiences visual or auditory disturbances but remains oriented. Generalized tonic-clonic seizures typically peak between 24 to 48 hours. Finally, delirium tremens, a medical emergency involving severe confusion, agitation, and autonomic hyperactivity, is a late manifestation that usually begins 48 to 72 hours after the last drink.

Step-by-Step Solution

1
Identify the earliest signs of alcohol withdrawal.
Mild tremors, anxiety, and diaphoresis are placed first in the sequence.
These minor withdrawal symptoms typically emerge within 6 to 12 hours after the last drink as the central nervous system begins to experience rebound hyperactivity.
2
Determine the next manifestation in the clinical timeline.
Hallucinations with intact orientation are placed second.
Alcoholic hallucinosis generally develops 12 to 24 hours after alcohol cessation. The client experiences hallucinations but remains oriented, differentiating this from delirium.
3
Identify the peak risk period for withdrawal seizures.
Generalized tonic-clonic seizures are placed third.
The risk for alcohol withdrawal seizures is highest between 24 and 48 hours post-cessation.
4
Identify the latest and most severe withdrawal complication.
Delirium tremens is placed last in the sequence.
Delirium tremens is a late-stage, life-threatening complication that usually begins 48 to 72 hours after the last drink, characterized by global confusion and autonomic instability.

Question 207Question →

A nurse is preparing to administer a prescribed intravenous (IV) push medication through a client's peripheral IV line. The client currently has a continuous primary IV infusion of a solution that is physically incompatible with the ordered IV push medication. In what order should the nurse perform the following actions to safely administer the medication? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence involves stopping the incompatible fluid, clamping the line to direct flow, flushing to clear the catheter, administering the medication, flushing again at the appropriate rate to clear residual drug, and finally restarting the primary fluid.
When administering an IV push medication through a line infusing an incompatible solution, the nurse must completely separate the two substances. The sequence starts with halting the pump and clamping the line to prevent retrograde flow. The first saline flush clears the line of the incompatible solution. The medication is then administered at the correct rate. Crucially, the second flush must be administered at the exact same rate as the medication to ensure the residual drug in the catheter is not pushed in too quickly. Finally, the line is unclamped and the pump is restarted.

Step-by-Step Solution

1
Stop the primary continuous IV infusion pump.
Incompatible fluid flow is halted.
Prevents the incompatible primary fluid from advancing into the lower tubing during preparation.
2
Clamp the primary IV tubing just above the injection port closest to the client.
Backward flow into the primary tubing is blocked.
Ensures that all injected fluids (flush and medication) are directed entirely into the client's vein rather than up the primary line.
3
Scrub the needleless connector and flush the port with 10 mL10\text{ mL} of sterile 0.9%0.9\% sodium chloride.
The IV catheter is cleared of incompatible fluid.
Prevents physical incompatibility (precipitation/crystallization) between the primary solution and the IV push medication.
4
Administer the prescribed IV push medication over the manufacturer's recommended time.
Therapeutic dose is delivered.
Ensures the medication is delivered safely according to pharmacological guidelines.
5
Flush the port again with 10 mL10\text{ mL} of 0.9%0.9\% sodium chloride at the same rate as the medication administration.
Residual medication in the catheter is cleared into the bloodstream.
Clears the medication from the catheter. Doing this at the same rate prevents the residual medication from being pushed into the circulation too rapidly (preventing speed shock).
6
Unclamp the primary IV tubing and restart the continuous IV infusion pump.
Primary continuous therapy is resumed.
Re-establishes the prescribed continuous maintenance or therapeutic IV fluids once the line is completely clear.

Key Concept

Safe administration of IV push medications through an incompatible infusing line requires strict isolation using a "flush-administer-flush" technique, with specific attention to clamping and flush administration rates.
Question 208Question →

While assessing a client receiving intravenous fluids via a central venous catheter (CVC), the nurse notes that the intravenous tubing has completely disconnected from the catheter hub. The client suddenly gasps, becomes severely dyspneic, and exhibits circumoral cyanosis. Arrange the following nursing actions in the correct order of prioritization.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct priority sequence is to first clamp the catheter, then position the client in the left lateral Trendelenburg position, administer high-flow oxygen, activate the rapid response team, and finally continuously monitor vital signs.
When a central venous catheter becomes disconnected, the negative intrathoracic pressure during inspiration can draw a lethal amount of air into the venous system, creating an air embolism. The nurse's absolute first priority is to stop the influx of air by clamping the catheter. Once the source is secured, the nurse must immediately position the client in the left lateral Trendelenburg position. This specific positioning traps the air in the apex of the right atrium, preventing it from entering the right ventricle and pulmonary artery. Next, administering 100% oxygen helps treat the resulting hypoxia and promotes the resorption of the nitrogen gas within the air bubble. After these immediate life-saving measures are rapidly executed, the nurse should activate the rapid response team to obtain advanced medical support. Finally, the nurse must provide continuous monitoring of the client's vital signs and oxygen saturation to carefully assess for ongoing hemodynamic instability while awaiting the team's arrival.

Step-by-Step Solution

1
Clamp the central venous catheter.
The source of air entry is immediately occluded.
Preventing any further air from entering the venous circulation is the most critical immediate action to minimize the size of the air embolism.
2
Place the client in the left lateral Trendelenburg position.
Air is trapped in the apex of the right atrium.
This specific position utilizes gravity to keep the air bubble away from the pulmonary valve, preventing it from migrating into the pulmonary artery and causing a massive pulmonary embolism.
3
Administer 100% oxygen via a non-rebreather mask.
Hypoxia is treated and nitrogen washout occurs.
High-concentration oxygen relieves the severe hypoxemia caused by the embolism and helps dissolve the air bubble faster by reducing the partial pressure of nitrogen in the blood.
4
Activate the rapid response team.
Advanced medical assistance is summoned.
An air embolism is a life-threatening emergency that requires immediate advanced interventions, which the rapid response team can provide.
5
Monitor vital signs and pulse oximetry continuously.
The client's hemodynamic and respiratory status is closely tracked.
Continuous monitoring allows the nurse to detect further clinical deterioration and evaluate the effectiveness of the initial emergency interventions.

Question 209Question →

A registered nurse enters a client's room and discovers the client lying supine on the floor next to the bed. 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 sequence is to first assess the client's ABCs, then examine for physical injuries, obtain vital signs, safely return the client to bed, and finally notify the provider and complete an occurrence report.
The nursing process and prioritization frameworks (such as ABCs and 'assess before implementing') guide post-fall management. The nurse must first ensure immediate survival (ABCs), then evaluate for specific injuries caused by the fall. Vital signs provide hemodynamic context. Only when the client is deemed safe to move should they be returned to bed to prevent exacerbating any unidentified injuries. Finally, administrative and medical reporting is completed once the client is safe.

Step-by-Step Solution

1
Determine the client's level of consciousness and assess airway, breathing, and circulation.
The nurse confirms the client's immediate life stability.
Basic life support principles dictate that airway, breathing, and circulation are the highest priority in any found-down scenario.
2
Examine the client for any obvious physical injuries, active bleeding, or musculoskeletal deformities.
The nurse identifies any traumatic injuries sustained during the fall.
Musculoskeletal or spinal injuries must be identified before moving the client to prevent exacerbation, paralysis, or severe pain.
3
Measure the client's vital signs and conduct a baseline neurological assessment.
The nurse establishes baseline physiological data post-fall.
Vital signs and neurological status (e.g., pupil reactivity, motor function) help rule out acute causes of the fall like orthostatic hypotension or stroke.
4
Safely assist the client back into the bed using a mechanical lift or additional staff members.
The client is securely repositioned in a safe environment.
Once cleared of severe injury precluding movement, the client should be moved safely utilizing appropriate ergonomics and assistance.
5
Notify the primary healthcare provider and complete a facility occurrence report.
The healthcare team is informed, and administrative documentation is completed.
The provider must be notified to evaluate the client or order diagnostics. An incident report is required for facility safety tracking but is not placed in the medical record.

Key Concept

Post-fall nursing management and injury prevention requires a systematic assessment to stabilize the client before moving them, followed by appropriate reporting.
Question 210Question →

A pediatric nurse is assessing the developmental milestones of various clients. Arrange the following play behaviors in the chronological order in which they typically emerge, from the earliest stage of childhood to the latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological order of play behaviors development is: Solitary play (infant playing alone), followed by Parallel play (toddler playing next to others), then Associative play (preschooler sharing without rules), and finally Cooperative play (school-age child playing a rule-based team sport).
Developmental play progresses sequentially as a child's cognitive and social skills mature. It begins with solitary play in infancy, moves to parallel play in toddlerhood, progresses to associative play during the preschool years, and matures into cooperative play with formal rules during the school-age years.

Step-by-Step Solution

1
Identify the developmental stage described by an infant playing alone.
This describes solitary play, which occurs in infancy (birth to 1 year).
Infants do not yet have the social development to interact with peers during play.
2
Identify the developmental stage described by a child playing next to another without interacting.
This describes parallel play, typical of toddlers (1 to 3 years).
Toddlers are egocentric but enjoy being near other children.
3
Identify the developmental stage described by children sharing toys without structured goals.
This describes associative play, typical of preschoolers (3 to 6 years).
Preschoolers develop the social skills to interact and share, though they lack formal organization.
4
Identify the developmental stage described by children playing a team sport with rules.
This describes cooperative play, typical of school-age children (6 to 12 years).
School-age children understand rules, teamwork, and shared objectives.
5
Sequence the identified stages chronologically.
Infancy (Solitary) -> Toddlerhood (Parallel) -> Preschool (Associative) -> School-age (Cooperative).
This order reflects the natural maturation of cognitive and psychosocial skills throughout childhood.

Question 211Question →

A nurse is preparing a client with severe, treatment-resistant major depressive disorder for electroconvulsive therapy (ECT). Arrange the following nursing actions in the chronological order they should be performed, from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological order is: providing education, ensuring NPO status, requesting the client to void and remove prosthetics, applying monitoring equipment in the treatment room, and finally positioning the client on their side during recovery.
The nursing care for a client undergoing electroconvulsive therapy (ECT) follows a strict chronological protocol to ensure clinical safety. It begins with comprehensive pre-procedure education and consent verification. On the day of the procedure, verifying NPO status is crucial to prevent aspiration. Immediately prior to transport, the client is asked to void and remove items that could cause injury, such as dentures and eyeglasses. In the treatment room, monitoring equipment is applied before anesthesia and the muscle relaxant are administered. Finally, during the post-procedure recovery phase, the client is positioned on their side to maintain an open airway and prevent aspiration as they regain consciousness.

Step-by-Step Solution

1
Identify the initial preparatory phase of the procedure.
Providing education about expected side effects (e.g., short-term memory loss) occurs first.
Education and informed consent must be completed before any physical preparations begin to respect client autonomy and ensure readiness.
2
Identify the early physical preparation on the day of the procedure.
Ensuring the client has been NPO for 6 to 8 hours.
Confirming NPO status is a morning priority to ensure it is safe to proceed with anesthesia and to minimize the risk of pulmonary aspiration.
3
Identify the immediate pre-procedure interventions on the unit.
Requesting the client to void and remove eyeglasses and dentures.
Emptying the bladder prevents incontinence during the induced seizure, and removing prosthetics prevents physical injury. This is done right before transport.
4
Identify the intra-procedure preparations.
Applying monitoring equipment, including a blood pressure cuff and pulse oximeter.
Once the client arrives in the treatment suite, baseline vital signs must be established and continuous monitoring initiated prior to the administration of the short-acting anesthetic.
5
Identify the post-procedure recovery interventions.
Positioning the client on their side.
Following the seizure, protecting the airway and preventing aspiration is the highest nursing priority while the client is unconscious and recovering from anesthesia.

Answer

The correct sequence is: assess the client, verify the UAP's competency, communicate directions, supervise the task, and evaluate the response.
The NCSBN outlines a structured delegation process that aligns with the nursing process. It begins with assessing the client and planning (determining clinical stability). Next, the RN must ensure the right person is assigned by verifying the UAP's competency. This is followed by communication, where the RN provides specific directions and reporting parameters. The RN then provides supervision while the task is performed. The process concludes with evaluation, where the RN assesses the client's response and ensures proper documentation.

Step-by-Step Solution

1
Identify the initial step of the delegation process.
Assess the client's clinical stability to determine if delegating the ambulation is appropriate.
The RN must first assess the client's needs to ensure the 'Right Circumstance' and 'Right Task' before initiating delegation.
2
Identify the second step.
Verify that the selected UAP possesses the required competency and training to perform the task.
The RN must verify the 'Right Person' by ensuring the delegatee has the proper knowledge and skills.
3
Identify the third step.
Communicate explicit directions regarding the ambulation distance and specific parameters for reporting.
The RN provides the 'Right Direction and Communication' by detailing exactly what needs to be done.
4
Identify the fourth step.
Provide appropriate supervision and remain available while the UAP assists the client.
The RN provides the 'Right Supervision' by monitoring the ongoing activity and being ready to intervene.

A public health nurse is facilitating a health education workshop for caregivers of pre-adolescent clients. The nurse outlines the predictable sequence of physiological changes marking female puberty. Arrange the following developmental milestones in the typical chronological order of their onset, from earliest to latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: Appearance of breast buds, followed by Growth of initial pubic hair, followed by Attainment of peak height velocity, and finally Onset of the first menstrual period.
The predictable sequence of female pubertal development begins with thelarche (breast budding), followed by pubarche (pubic hair development). As puberty progresses, the adolescent experiences a rapid growth spurt (peak height velocity), which is ultimately followed by menarche (the onset of menstruation) as a late stage of development.

Step-by-Step Solution

1
Identify the earliest sign of female puberty.
Appearance of breast buds (thelarche) is recognized as the first physiological change.
Thelarche marks the beginning of physical maturation and the onset of puberty.
2
Determine the subsequent developmental milestone.
Growth of initial pubic hair (pubarche) follows thelarche.
Pubarche typically occurs within months after breast budding begins.
3
Place the growth spurt in the sequence.
Attainment of peak height velocity is positioned third.
The rapid growth spurt happens during mid-puberty, after initial primary and secondary sex characteristics have started but before full reproductive maturity.
4
Identify the final developmental marker in this sequence.
Onset of the first menstrual period (menarche) is placed last.
Menarche is a late pubertal event, signaling the later stages of physical maturation, typically occurring about 2 years after thelarche.

Question 214Question →

A nurse is discontinuing a client's central venous catheter (CVC). Immediately after the catheter is removed, the client gasps, reports sudden severe chest pain, and becomes distinctly cyanotic. The nurse suspects a venous air embolism. Arrange the following nursing interventions in the correct order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a suspected air embolism is: 1) Apply a sterile, occlusive dressing, 2) Position the client in the left lateral Trendelenburg position, 3) Administer 100% oxygen, 4) Notify the healthcare provider, and 5) Obtain a complete set of vital signs.
A venous air embolism is a life-threatening emergency requiring immediate, sequential actions to prevent cardiac arrest. The first priority is always to stop the source of the problem by occluding the central line insertion site. Next, Durant's maneuver (left lateral Trendelenburg) is utilized to mechanically trap the air in the right ventricle apex, preventing pulmonary outflow obstruction. Only after securing the site and positioning the client should the nurse administer 100% oxygen to treat hypoxemia and reduce the nitrogen bubble size. Finally, the nurse calls for advanced help and continues to closely monitor the client's hemodynamic status.

Step-by-Step Solution

1
Halt the influx of air.
Apply a sterile, occlusive dressing over the central line site.
The priority is to eliminate the root cause of the crisis to prevent the air embolus from enlarging.
2
Prevent embolus migration.
Place the client in the left lateral Trendelenburg position.
This specific position (Durant's maneuver) utilizes gravity to trap the existing air in the right ventricle, preventing it from traveling into the pulmonary artery.
3
Treat hypoxia and shrink the embolus.
Administer 100% oxygen via a non-rebreather mask.
High-concentration oxygen relieves systemic hypoxemia and speeds up the reabsorption of nitrogen gas from the bubble.
4
Escalate care.
Notify the healthcare provider and rapid response team.
Advanced interventions and potential resuscitation will be required; help must be summoned.
5
Reassess and monitor.
Obtain vital signs and monitor oxygen saturation.
Continuous monitoring guides ongoing resuscitation efforts and evaluates the effectiveness of the initial interventions.

Key Concept

Management of a venous air embolism prioritizes stopping the air source, utilizing gravity to trap the air in the right ventricle (Durant's maneuver), and treating severe hypoxia.
Question 215Question →

A registered nurse (RN) observes an unlicensed assistive personnel (UAP) independently silencing an alarm on a client's patient-controlled analgesia (PCA) pump. Place the RN's actions in the correct order of priority, from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate safety intervention, followed by client assessment, equipment verification, staff supervision, and finally administrative reporting.
When managing a scope of practice violation, the RN must follow a strict prioritization framework: halt the unsafe action to prevent harm, assess the client using the nursing process, secure the equipment, provide supervisory education, and complete administrative documentation.

Step-by-Step Solution

1
Instruct the UAP to step away from the PCA pump immediately.
The unsafe action is halted.
Silencing alarms or manipulating a PCA pump is entirely outside a UAP's scope of practice. Stopping the action prevents potential medication errors.
2
Assess the client's respiratory rate, oxygen saturation, and level of sedation.
The client's clinical stability is determined.

Question 216Question →

A client with type 1 diabetes mellitus is admitted to the intensive care unit with diabetic ketoacidosis (DKA). The client is lethargic, exhibits Kussmaul respirations, and reports severe abdominal pain. Initial laboratory results indicate a blood glucose of 610 mg/dL (33.9 mmol/L) and a serum pH of 7.15. The healthcare provider prescribes a comprehensive DKA treatment protocol. Arrange the following nursing interventions in the correct chronological order of implementation.

Show answer & explanation

Answer

The correct sequence for managing Diabetic Ketoacidosis is to first initiate fluid resuscitation with 0.9% sodium chloride, verify the potassium level is above 3.3 mEq/L, begin the regular insulin infusion, add 5% dextrose once the glucose level reaches 250 mg/dL, and finally overlap subcutaneous insulin before discontinuing the intravenous insulin infusion.
The priority sequence for diabetic ketoacidosis (DKA) management addresses the most acute life threats first: hypovolemia, electrolyte disturbances, and acidosis. Fluid resuscitation (0.9% sodium chloride) is always the first intervention to restore perfusion. Next, potassium must be verified (> 3.3 mEq/L) before administering insulin to prevent fatal hypokalemia. Following this, regular IV insulin is started to stop ketogenesis and correct the acidosis. Once blood glucose drops to 250 mg/dL, dextrose must be added to IV fluids to prevent hypoglycemia and cerebral edema. Finally, subcutaneous insulin must overlap with the IV infusion to prevent rebound ketoacidosis.

Step-by-Step Solution

1
Prioritize fluid resuscitation
Intravenous 0.9% sodium chloride is administered rapidly.
Severe dehydration from osmotic diuresis requires immediate intravascular volume expansion to maintain tissue perfusion and hemodynamic stability.
2
Assess electrolyte safety
Serum potassium is verified to be > 3.3 mEq/L.
Insulin therapy drives potassium into the cells; starting insulin with profound hypokalemia can cause fatal cardiac dysrhythmias.
3
Initiate insulin therapy
A continuous intravenous infusion of regular insulin is started.
Insulin is required to correct the severe hyperglycemia, stop lipolysis, and reverse the metabolic acidosis.
4
Modify fluid composition based on glucose response
5% dextrose is added when blood glucose decreases to 250 mg/dL (13.9 mmol/L).
Adding dextrose prevents a rapid decline in blood glucose (hypoglycemia) and limits sudden osmotic shifts that cause cerebral edema.
5
Transition to maintenance therapy
Subcutaneous insulin is administered prior to stopping the IV infusion.
An overlap ensures continuous insulin coverage, preventing rebound ketoacidosis when the short-acting IV insulin is discontinued.

A nurse is caring for a client with a T4 spinal cord injury who suddenly reports a severe, pounding headache. Assessment reveals profuse diaphoresis above the level of the injury, a blood pressure of 210/115 mm Hg, and a heart rate of 54 bpm. Arrange the following nursing interventions 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 is: Place the client in a high Fowler's position, assess the urinary catheter for kinks, examine the rectum for impaction, and finally administer the prescribed antihypertensive medication.
The correct sequence prioritizes immediate physiological safety by inducing orthostatic hypotension through upright positioning, followed by a systematic assessment to eliminate the most common noxious stimuli (bladder then bowel), and finally utilizing pharmacological intervention if the stimulus cannot be resolved.

Step-by-Step Solution

1
Recognize the clinical presentation of autonomic dysreflexia.
The client has a T4 spinal cord injury, severe hypertension, bradycardia, headache, and diaphoresis.
Identifying the medical emergency is required to initiate the correct crisis management protocol.
2
Determine the priority first action to mitigate immediate risk.
Positioning the client upright in a high Fowler's position is the immediate first step.
Raising the head of the bed induces orthostatic hypotension, which rapidly decreases the blood pressure and minimizes the risk of a stroke.
3
Sequence the assessment for triggering noxious stimuli.
Checking the bladder and catheter comes before checking the bowel.
Bladder distention is the most frequent cause of autonomic dysreflexia, making it the highest priority assessment after positioning. Bowel impaction is the second most common.
4
Determine the role of pharmacological intervention.
Administering antihypertensive medication is the final step in this sequence.
Medications are indicated only if the blood pressure remains elevated after the noxious stimuli have been identified and removed, or if the stimulus cannot be immediately resolved.

Key Concept

Autonomic dysreflexia is a life-threatening emergency in clients with spinal cord injuries at or above T6, requiring immediate upright positioning followed by the identification and removal of noxious stimuli (usually bladder or bowel).
Question 218Question →

A client with viral encephalitis is experiencing severe delirium and extreme psychomotor agitation. The client abruptly lunges forward and begins forcefully pulling at their femoral arterial sheath. Recognizing an imminent risk for catastrophic hemorrhage, the nurse determines that emergency physical restraints are required. Arrange the following nursing actions in the correct chronological sequence from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes immediate physical safety (calling for help and applying restraints), followed by physiological assessment (circulation), legal notification (contacting the provider), and finally, administrative documentation.
In a life-threatening emergency where a client is actively pulling at a critical arterial line, the nurse must prioritize immediate physical safety. Calling for assistance ensures the intervention can be performed safely. Once help is present, applying the restraints prevents catastrophic hemorrhage. Immediately after application, circulation must be assessed to prevent limb ischemia. Finally, administrative duties are completed: the healthcare provider must be notified to evaluate the client and provide a formal prescription, followed by comprehensive documentation of the event.

Step-by-Step Solution

1
Summon additional personnel
Ensures adequate staff to safely manage a combative client
Attempting to restrain a violent client alone increases the risk of injury to both the nurse and the client.
2
Apply limb restraints
Secures the client's extremities to prevent removal of the arterial sheath
Immediate physical restraint is required to prevent life-threatening hemorrhage.
3
Assess distal circulation
Verifies that the restraints are not compromising blood flow
Restraints applied too tightly can cause rapid ischemic tissue damage.
4
Notify the healthcare provider
Initiates the formal evaluation and prescription process
Emergency restraints may be applied without a prior order, but the provider must evaluate the client and prescribe them immediately afterward.
5
Document the event
Provides a legal and clinical record of the emergency application
Documentation must include the behavior, failed alternatives, and exact time of application to meet regulatory standards.

A registered nurse on a neurology step-down unit is developing a care plan for an individual with acute encephalitis who is increasingly agitated and repeatedly attempting to dislodge a central venous catheter. Arrange the following interventions in the correct sequence, from the least restrictive action to the most restrictive measure.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from least to most restrictive is: 1) Evaluate for physiological causes, 2) Implement environmental calming strategies, 3) Cover the central venous catheter, 4) Enlist a hospital sitter, 5) Apply non-tethered soft mittens, and 6) Secure bilateral soft wrist restraints.
The standard of nursing care mandates exhausting all least restrictive alternatives before utilizing physical restraints. The proper sequence begins with the foundational nursing process (assessment of physiological causes) and logically progresses through environmental manipulation, camouflaging medical devices, utilizing direct human observation (sitter), and applying non-tethered physical devices (mittens), before culminating in the most restrictive measure possible (tethered limb restraints).

Step-by-Step Solution

1
Apply the nursing process to assess the root cause of agitation.
Physiological needs such as pain, hypoxia, or urinary retention are identified and addressed first.
Assessing for and treating the underlying cause is the least restrictive and most fundamental nursing intervention.
2
Implement non-physical, non-restrictive environmental modifications.
Sensory overload is minimized by dimming lights and reducing ambient noise.
Environmental manipulation is a primary non-pharmacological alternative to restraints that preserves full client autonomy.
3
Conceal the medical device without restricting the client.
The central venous catheter is covered with a protective elastic sleeve.
Removing the visual stimulus of the tubing prevents the individual from pulling it while maintaining complete freedom of movement.
4
Utilize human resources for continuous observation and redirection.
A trained hospital sitter is stationed in the room.
A sitter provides constant supervision and verbal de-escalation, which is more restrictive than environmental changes but less restrictive than physical devices.
5
Implement the least restrictive physical device.
Soft protective mittens are applied but not tied down to the bed.
Mittens prevent the grasping of lines while still allowing the individual full range of motion of their arms.
6
Apply physical limb restraints as a last resort.
Bilateral soft wrist restraints are secured to the movable portion of the bed frame following a provider order.
Limb restraints entirely restrict extremity movement and are the most restrictive intervention, legally requiring all other alternatives to have failed.

Question 220Question →

A nurse is preparing to perform Leopold maneuvers on a pregnant client at 3636 weeks of gestation to assess fetal position and presentation. In what order should the nurse perform the assessment steps? Arrange the actions in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for Leopold maneuvers is to first palpate the fundus, then palpate the lateral sides of the abdomen, followed by grasping the lower uterine segment, and finally facing the client's feet to palpate the pelvic inlet.
Leopold maneuvers must be performed in a specific, standardized sequence to systematically identify fetal position. The sequence logically begins at the top of the uterus (fundal grip) while facing the client's head, moves to the sides (lateral grip), progresses to grasping the lower uterus (Pawlik's grip), and concludes by the nurse turning to face the client's feet to assess the pelvic inlet (pelvic grip).

Step-by-Step Solution

1
Palpate the uterine fundus (First Maneuver).
Determines whether the fetal head or breech is in the upper uterine pole.
Establishes fetal presentation and lie.
2
Palpate the lateral sides of the maternal abdomen (Second Maneuver).
Locates the smooth fetal back and the irregular extremities.
Determines fetal position and identifies the optimal location to auscultate the fetal heart rate.
3
Grasp the lower uterine segment just above the symphysis pubis (Third Maneuver).
Identifies the presenting part in the lower pole of the uterus.
Confirms the findings of the first maneuver and assesses whether the presenting part is engaged in the maternal pelvis.
4
Face the client's feet and palpate toward the pelvic inlet (Fourth Maneuver).
Determines the cephalic prominence and fetal attitude.
Assesses the degree of fetal head flexion (attitude) and descent into the pelvis.

Key Concept

Leopold maneuvers are a systematic, four-step method of abdominal palpation used to determine fetal lie, presentation, position, and attitude during the antepartum period.
