Cevap

The correct sequence of actions is to first verify airway and oxygenation, then elevate the head of the bed to 30 degrees, subsequently notify the registered nurse and provider, implement seizure precautions, and finally document the event.
In any acute neurological decline involving suspected increased intracranial pressure, the ABCs (Airway, Breathing, Circulation) take strict precedence. The nurse must first ensure the brain is receiving oxygen to prevent massive vessel dilation. Next, the nurse uses physical positioning to drain fluid from the head. Only after these immediate stabilization steps are complete should the nurse escalate the emergency to higher-level providers, secure the environment against secondary complications, and chart the event.

Adım Adım Çözüm

1
Verify airway patency and ensure oxygen delivery.
Prevents cerebral hypoxia and hypercapnia.
Hypoxia and retained carbon dioxide cause cerebral blood vessels to dilate, which severely and rapidly increases intracranial pressure.
2
Elevate the head of the bed and align the neck.
Facilitates venous return from the brain.
A 30-degree elevation with a neutral neck alignment uses gravity to drain blood through the jugular veins, decreasing cranial volume and pressure.
3
Notify the RN and healthcare provider.
Escalates the clinical emergency to advanced providers.
The client is exhibiting Cushing's triad (bradycardia, hypertension, altered mental status), which signals impending brainstem herniation requiring urgent medical intervention.
4
Implement seizure precautions and lower stimuli.
Protects the client from secondary injury and reduces cerebral metabolic demand.
A damaged, pressurized brain is highly susceptible to seizure activity, and environmental stress can further elevate intracranial pressure.
5
Document the event and vital signs.
Creates an accurate chronological record of the clinical decline.
Documentation provides critical data for the healthcare team but is an administrative task that should never delay life-saving bedside interventions.

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

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence ensures maximum safety by first establishing the environment (positioning and locking the wheelchair on the strong side), stabilizing the client (sitting and dangling), applying safety equipment (gait belt), and finally executing the transfer.
Safe client mobility requires a rigid sequential approach: environmental preparation (chair placement and locking) must occur before client preparation (positioning and safety devices), which must occur before the physical movement (standing and pivoting).

Adım Adım Çözüm

1
Place the wheelchair on the client's left side at a 45-degree angle to the bed.
The wheelchair is properly positioned on the client's unaffected side.
Because the client has right-sided weakness, placing the chair on the left allows them to use their stronger arm and leg to support their weight and guide the transfer.
2
Lock the brakes on both the bed and the wheelchair.
The environment is completely immobilized.
Locking the brakes prevents sudden, unexpected movement of the bed or chair, which is a primary cause of transfer-related injuries.
3
Lower the bed and assist the client to sit on the edge with feet flat on the floor.
The client is in a dangling position with a solid base of support.
Dangling allows the cardiovascular system to adjust to the upright position, minimizing dizziness, while flat feet provide necessary stability.
4
Securely fasten a transfer (gait) belt around the client's waist.
Safety equipment is in place.
Applying the gait belt while the client is safely seated ensures a snug fit, providing the nurse with a secure hold to safely guide the client's movements.
5
Assist the client to stand and pivot on the strong leg toward the wheelchair.
The client safely completes the transfer to the wheelchair.
Pivoting on the unaffected left leg ensures the client can support their own weight securely during the transition into the chair.

Cevap: Notify the registered nurse (RN) immediately regarding the vital sign trends.

Cevap

Notify the registered nurse (RN) immediately regarding the vital sign trends.
The client's increasing heart rate and decreasing blood pressure in the immediate postoperative period are critical indicators of potential hemorrhage or hypovolemic shock. The priority action to reduce the client's risk is to recognize this physiological decline and immediately notify the RN or healthcare provider for urgent collaborative intervention.

Adım Adım Çözüm

1
Analyze the client's postoperative vital signs.
The client is exhibiting a rising heart rate (tachycardia) and a falling blood pressure (hypotension).
Tracking vital sign trends helps identify early physiological decline.
2
Correlate the findings with potential surgical complications.
Tachycardia combined with hypotension shortly after major abdominal surgery is a classic early indicator of hypovolemic shock or internal hemorrhage.
Recognizing the mechanism behind the vital sign changes is necessary for risk reduction.
3
Determine the appropriate scope of practice for the PN.
The PN must immediately report these critical findings to the supervising RN or healthcare provider.
Rapid escalation ensures the client receives timely medical assessment and intervention, preventing further harm.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first flatten the bed, then position the client's limbs with a pillow between the knees, position the staff on the destination side, grasp the draw sheet on the far side, and finally roll the client as a single unit on a count of three.
Logrolling is a mobility technique used to turn a client whose spine must be kept in straight alignment, particularly after spinal fusion surgery. The procedure requires careful sequential preparation: flattening the bed to align the spine, positioning the limbs to prevent dragging and maintain hip alignment, organizing the staff around the bed, establishing a firm grip on the draw sheet, and executing a coordinated turn as a single unit to prevent spinal torque.

Adım Adım Çözüm

1
Lower the head of the bed to ensure the mattress is completely flat.
The client is in a flat, supine position.
A flat surface is required to prevent spinal flexion and maintain straight alignment during the maneuver.
2
Cross the client's arms over their chest and place a pillow between their knees.
The client's extremities are secured and aligned.
Crossing the arms prevents dragging, and the pillow keeps the hips and lumbar spine aligned without twisting.
3
Position two staff members on the side of the bed toward which the client will be turned.
Staff are optimally positioned for the transfer.
Positioning on the destination side allows the staff to safely pull the client's weight toward their own center of gravity.
4
Reach across the client and firmly grasp the draw sheet on the opposite side.
Staff have a secure hold on the friction-reducing device.
The draw sheet distributes the pulling force evenly across the client's body length.
5
Roll the client smoothly as a single unit on a coordinated count of three.
The client is successfully turned onto their side.
Moving the body as one continuous unit (logrolling) prevents any dangerous torque or twisting on the postoperative spine.

A client with a seizure disorder is receiving continuous enteral nutrition via a percutaneous endoscopic gastrostomy (PEG) tube. The practical nurse must administer a scheduled dose of phenytoin oral suspension through the tube. Arrange the following actions in the correct sequence to ensure safe administration and maximize drug absorption.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence requires stopping the feeding 1-2 hours before, verifying tube placement/residual, flushing with water, administering the phenytoin, flushing again with water, and leaving the feeding off for another 1-2 hours.
Phenytoin has a well-documented and severe interaction with enteral nutritional formulas. The formula significantly decreases the gastrointestinal absorption of the drug, which can lead to subtherapeutic serum levels and seizures. Therefore, the feeding must be stopped 1 to 2 hours before administration. Standard tube medication safety follows: verify placement and residual, flush with water, administer the medication, and flush again. Finally, the feeding must remain off for an additional 1 to 2 hours to allow the drug to absorb fully without interference.

Adım Adım Çözüm

1
Stop the continuous enteral feeding 1 to 2 hours prior to the scheduled medication time.
The stomach empties of formula before the medication arrives.
Enteral formula contains proteins and calcium that heavily bind to phenytoin, leading to subtherapeutic drug levels and potential breakthrough seizures.
2
Verify gastrostomy tube placement and measure the gastric residual volume.
Safe route for administration is confirmed.
Checking placement and residual prevents pulmonary aspiration and ensures the gastrointestinal tract is tolerating fluids.
3
Flush the gastrostomy tube with 30 mL of water.
The internal lumen of the tube is cleared of formula.
This prevents direct physical incompatibility and crystallization between the enteral formula and the phenytoin suspension inside the tube.
4
Administer the prescribed dose of liquid phenytoin suspension.
The therapeutic agent is delivered.
Phenytoin must be given as an isolated suspension to ensure proper absorption.
5
Flush the gastrostomy tube with an additional 30 mL of water.
The medication is completely cleared from the tubing.
Ensures the client receives the full prescribed dose and prevents tube occlusion from the medication.
6
Keep the enteral feeding paused for 1 to 2 hours before restarting the continuous infusion.
The drug absorbs fully across the gastrointestinal mucosa without interference.
Immediate resumption of feeding would cause the formula to bind to the phenytoin in the stomach, rendering the medication ineffective.

Anahtar Kavram

Enteral administration of phenytoin requires strictly holding continuous nutritional feedings 1 to 2 hours before and after administration to prevent decreased drug bioavailability due to protein binding.

A practical nurse (PN) is caring for an 82-year-old client who is receiving oxygen therapy for a severe respiratory infection. The client suddenly becomes highly restless, confused, and attempts to pull off the oxygen cannula. Which action should the PN take first?

Cevabı ve açıklamayı göster

Cevap: Check the client's oxygen saturation level using a pulse oximeter.

Cevap

Check the client's oxygen saturation level using a pulse oximeter.
The correct action directly evaluates the client's respiratory status. In older adults, sudden restlessness, agitation, and confusion are frequently the earliest signs of systemic hypoxia. Using the ABC (Airway, Breathing, Circulation) framework, the practical nurse must first gather data regarding oxygenation to determine if a life-threatening complication is occurring.

Adım Adım Çözüm

1
Identify the sudden change in the client's condition (restlessness and confusion).
Recognize that these are neurological manifestations of a potential physiological compromise.
Early identification of subtle changes helps prevent severe complications.
2
Correlate the client's symptoms with their primary diagnosis (respiratory infection).
Determine that impaired gas exchange and resulting hypoxia are highly probable.
Restlessness is often the first clinical sign of hypoxia, especially in older adults.
3
Apply the ABC (Airway, Breathing, Circulation) priority framework.
Select the action that directly assesses the client's breathing and oxygenation status.
Physiological needs related to oxygenation always take precedence over comfort measures or physical restraints.

An unlicensed assistive personnel (UAP) reports that a 76-year-old client who underwent a percutaneous liver biopsy three hours ago is now highly restless and disoriented. The client also complains of a new, dull ache in the right shoulder. Baseline vital signs were blood pressure 138/82 mm Hg and pulse 76 bpm. Current vital signs are blood pressure 108/74 mm Hg, pulse 112 bpm, and respirations 22/min. Which action should the practical nurse implement first?

Cevabı ve açıklamayı göster

Cevap: Position the client flat on the right side and immediately notify the registered nurse.

Cevap

The priority action is to position the client flat on the right side and immediately notify the registered nurse.
The client is demonstrating classic, critical signs of internal hemorrhage and hypovolemic shock. Restlessness and confusion are early manifestations of cerebral hypoperfusion. The new right shoulder ache (Kehr's sign) indicates diaphragmatic irritation from accumulating intra-abdominal blood. Furthermore, the vital signs reveal a significantly narrowed pulse pressure (from 56 mm Hg to 34 mm Hg) and tachycardia, which represent the body's compensatory mechanisms for acute volume loss. Positioning the client flat on the right side uses the rib cage to apply external pressure to the liver capsule, helping to tamponade the bleeding site. Because the client is actively deteriorating, the registered nurse must be notified immediately to initiate medical resuscitation.

Adım Adım Çözüm

1
Analyze the clinical cues presented by the client.
The client exhibits restlessness, disorientation, right shoulder pain, tachycardia (112 bpm), and a narrowing pulse pressure (from 56 mm Hg baseline down to 34 mm Hg).
Identifying these grouped cues is essential to recognize the systemic signs of internal bleeding and hypoperfusion.
2
Correlate the clinical cues with the recent procedure.
The client had a highly vascular liver biopsy. The right shoulder pain is recognized as Kehr's sign, which is referred pain from blood irritating the phrenic nerve and diaphragm.
Understanding the anatomical risks of a liver biopsy connects the localized referred pain and systemic shock signs to active hemorrhage.
3
Determine the priority intervention within the practical nursing scope of practice.
The nurse must apply direct pressure to the internal biopsy site by positioning the client flat on the right side and escalate the critical findings to the RN.
Airway, Breathing, and Circulation (ABC) prioritization dictates that active hemorrhage and impending shock must be addressed immediately with mechanical tamponade and emergency escalation.

Cevabı ve açıklamayı göster

Cevap

To ascend a step, the client starts in a tripod stance, shifts weight onto the crutches, steps up with the unaffected leg, shifts weight onto the unaffected leg, and finally brings the crutches and affected leg up together.
The fundamental principle for ascending stairs with an assistive device is 'up with the good.' The client must first establish stability in a tripod position. By bearing weight on the hands, the client can safely lift the strong, unaffected leg onto the step. Once the strong leg is anchored on the higher level, the client shifts their weight onto it. This strong leg now acts as the elevator for the rest of the body, allowing the client to safely bring up the crutches and the non-weight-bearing injured leg simultaneously without compromising balance or the surgical/injury site.

Adım Adım Çözüm

1
Assume the tripod stance close to the base of the stairs.
A wide, stable base of support is established.
Proper alignment prevents backward falls when initiating the upward movement.
2
Bear the full body weight evenly on the handgrips of both crutches.
The legs are completely unweighted.
This allows the client to freely lift the unaffected leg without losing balance.
3
Advance the unaffected left leg onto the step above.
The strong leg is planted on the higher elevation.
The unaffected leg must lead to provide the necessary power to lift the body.
4
Shift the body weight from the crutches onto the unaffected left leg.
The upper body and crutches are now unweighted.
Weight must be on the strong leg so the crutches can be safely lifted off the lower level.
5
Lift the affected right leg and both crutches simultaneously to the step.
The client is now standing with both feet and crutches on the new step.
This completes the movement while ensuring zero weight is placed on the injured extremity.

At the start of the shift, a practical nurse observes a 77-year-old client who is hospitalized for conservative management of a pelvic fracture. The client, who was previously lucid and conversant, is now restless, pulling at their intravenous tubing, and speaking incoherently. Current vital signs reveal a heart rate of 115 beats/minute, respirations of 26 breaths/minute, and a blood pressure of 94/58 mm Hg. Based on these findings, which of the following is the priority action for the practical nurse?

Cevabı ve açıklamayı göster

Cevap: Obtain an oxygen saturation reading, elevate the head of the bed, and immediately alert the supervising registered nurse.

Cevap

The correct action is to prioritize respiratory assessment (oxygen saturation), position the client to facilitate optimal breathing, and urgently escalate the physiological changes to the registered nurse.
Acute confusion, tachycardia, tachypnea, and borderline hypotension in a client with a major bone fracture are classic early signs of a severe physiological complication, such as a fat embolism or hemorrhagic shock. According to the ABC (Airway, Breathing, Circulation) framework, the practical nurse must first assess oxygenation, support breathing by elevating the head of the bed, and immediately notify the registered nurse for advanced collaborative interventions.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client exhibits acute mental status changes, tachycardia (115 beats/minute), tachypnea (26 breaths/minute), and borderline hypotension.
Identifying sudden changes from a previously stable baseline is essential for early recognition of life-threatening complications.
2
Correlate the assessment findings with the admitting diagnosis.
A pelvic fracture places the client at high risk for severe complications such as fat embolism syndrome or internal hemorrhagic shock.
Understanding diagnostic risk factors helps differentiate between expected aging-related hospital delirium and a physiological medical emergency.
3
Apply the Airway-Breathing-Circulation (ABC) priority framework.
The elevated respiratory rate and heart rate suggest a cardiopulmonary crisis (hypoxia or shock), making oxygenation assessment and immediate registered nurse notification the absolute highest priorities.
Acute physiological instability always takes precedence over psychosocial interventions, basic safety measures, or routine monitoring.

Cevap: Cross-check the name and date of birth on the identification band against the medication record.; Inquire if the client has any history of hypersensitivity or adverse reactions to medications.; Ensure the medication name, dose, and route on the package match the provider's prescription.

Cevap

The correct actions are cross-checking the name and date of birth against the medication record, inquiring about medication hypersensitivity, and ensuring the medication details match the prescription.
Safe medication administration requires strict adherence to the fundamental rights of medication administration. This includes verifying the correct client using two distinct personal identifiers (such as name and date of birth on an identification band), confirming the correct drug, dose, and route against the active prescription, and assessing for any potential allergies prior to giving the drug to prevent adverse reactions.

Adım Adım Çözüm

1
Identify the standard rights of medication administration relevant to the scenario.
The nurse must verify the right client, right drug, right dose, right route, and right time, as well as assess for allergies.
Adhering to these fundamental standards prevents medication errors and protects client safety.
2
Evaluate each option against safe administration protocols.
Using two client-specific identifiers, checking for allergies, and verifying the prescription are safe actions. Using room numbers or leaving medications unattended are unsafe actions.
Room numbers are not client-specific identifiers, and leaving medications unattended risks administration to the wrong client or missed doses.

The correct sequence is: Stop the transfusion immediately, maintain IV access with new tubing and 0.9% sodium chloride, assess vital signs and cardiopulmonary status, report findings to the supervising RN, and finally collect required blood and urine specimens.
In any emergency where a therapeutic intervention causes severe harm (such as a hemolytic transfusion reaction), the absolute first priority is to stop the intervention. Following immediate cessation, the nurse must secure the IV line with normal saline using new tubing to prevent further infusion of the blood while keeping the vein open for emergency drugs. Next, the nurse assesses the client to gather critical physiological data, reports these findings to the RN for medical escalation, and finally executes post-reaction protocol steps such as collecting diagnostic specimens.

Adım Adım Çözüm

1
Stop the administration of the blood product immediately.
The infusion of the potentially incompatible blood is halted.
This is the most critical first step to reduce the risk of life-threatening complications by preventing further antigen exposure.
2
Maintain intravenous access with a new tubing set primed with 0.9% sodium chloride.
The IV line remains patent without infusing more of the reacted blood.
Vascular access is required for emergency medications. Flushing with the old tubing would incorrectly push the remaining blood in the line into the client, worsening the reaction.
3
Obtain the client's vital signs and complete a focused cardiopulmonary assessment.
Objective baseline data regarding the severity of the reaction is gathered.
The nurse needs precise assessment data (e.g., blood pressure, oxygen saturation, lung sounds) to accurately report the client's physiological status.
4
Report the assessment findings and suspected reaction to the supervising registered nurse (RN).
The RN is alerted to escalate the situation to the healthcare provider.
Effective escalation requires providing the RN with current, accurate assessment data so they can collaborate on immediate medical management.
5
Collect required blood and urine specimens to evaluate for potential hemolysis.
Samples are prepared for laboratory and blood bank analysis.
Diagnostic evaluation for hemolytic or other adverse reactions occurs safely only after the client's acute airway and circulatory needs are secured.

Cevap: Administering a scheduled subcutaneous injection of epoetin alfa to a client with chronic kidney disease whose hemoglobin is 9.8 g/dL.

Cevap

The correct action is to administer the scheduled subcutaneous injection of epoetin alfa to the client with chronic kidney disease whose hemoglobin is 9.8 g/dL.
The administration of a subcutaneous injection is firmly within the practical nurse (PN) scope of practice. Furthermore, the clinical data supports the action: epoetin alfa is used to treat anemia associated with chronic kidney disease. The goal of therapy is to maintain hemoglobin levels between 10 and 11 g/dL. Because the client's hemoglobin is 9.8 g/dL, the medication is indicated and safe to administer. It would only be withheld if the level exceeded 11.0 g/dL due to the increased risk of thrombotic events.

Adım Adım Çözüm

1
Evaluate each task against the practical nurse (PN) scope of practice constraints.
Intravenous (IV) push medications are generally outside the PN scope of practice, especially for acute conditions.
The NCLEX assumes standard PN scope, which excludes IV push and tasks requiring advanced clinical judgment.
2
Analyze the laboratory data provided for the remaining pharmacological interventions.
The client receiving spironolactone has hyperkalemia (5.8 mEq/L), which is a strict contraindication for a potassium-sparing diuretic.
Administering spironolactone would further increase potassium, risking fatal cardiac dysrhythmias.
3
Assess the immunization order against current health status contraindications.
The MMR vaccine is a live virus and is contraindicated for the client who is 12 weeks pregnant.
Live vaccines pose a severe teratogenic risk to the developing fetus.
4
Verify the safety and appropriateness of the epoetin alfa administration.
Subcutaneous administration is within PN scope, and a hemoglobin of 9.8 g/dL is an appropriate level to receive the medication.
Epoetin alfa is given to stimulate red blood cell production; it is only withheld when hemoglobin exceeds 11.0 g/dL due to cardiovascular risks.

The correct sequence is to first administer a fast-acting carbohydrate (apple juice), wait 15 minutes, recheck the capillary blood glucose, and finally provide a complex carbohydrate and protein snack.
For a conscious client experiencing acute hypoglycemia (blood glucose less than 70 mg/dL), the standard evidence-based protocol is the 'Rule of 15'. The nurse must first administer 15 grams of a fast-acting, easily digestible carbohydrate (such as 4 ounces of juice) to quickly raise the blood sugar. The nurse then waits exactly 15 minutes to allow for absorption before rechecking the blood glucose level to see if it has risen above 70 mg/dL. Once the acute hypoglycemia is resolved, a complex carbohydrate and protein snack (like peanut butter and crackers) is provided to maintain the blood glucose level and prevent a subsequent drop.

A practical nurse receives shift report for a client who underwent a right above-the-knee amputation 48 hours ago. To promote optimal physical mobility and prevent a major musculoskeletal complication associated with this surgery, which positioning intervention should the nurse implement?

Cevabı ve açıklamayı göster

Cevap: Assist the client into a prone position for 20 to 30 minutes several times a day.

Cevap

The correct intervention is to assist the client into a prone position for 20 to 30 minutes several times a day to prevent hip flexion contractures.
After an above-the-knee amputation, preventing hip flexion contractures is a primary basic care goal. Placing the client in a prone position for 20 to 30 minutes three to four times a day actively stretches the hip flexor muscles and prevents contracture formation. This extension is absolutely essential for the client's future ability to use a prosthesis and ambulate effectively.

Adım Adım Çözüm

1
Analyze the client's postoperative timeline.
The client is 48 hours post-amputation.
Care protocols for amputations change significantly after the first 24 hours, particularly regarding limb elevation.
2
Identify the major musculoskeletal complication associated with above-the-knee amputations.
Hip flexion contracture is a severe complication that impedes future ambulation and prosthetic fitting.
Anticipating this complication allows the nurse to prioritize preventive positioning measures.

Evaluate the physiological impact of each positioning option.
Elevation, high-Fowler's, and prolonged sitting all promote hip flexion. Prone positioning promotes hip extension.
To prevent a flexion contracture, the joint must be periodically extended.
4
Select the intervention that actively prevents the complication.
Assisting the client to lie prone for 20-30 minutes stretches the hip flexors.
This is the evidence-based standard of care for contracture prevention in amputation clients.

A practical nurse is reviewing morning laboratory results before administering a scheduled dose of oral furosemide to a client. The client's serum potassium level is reported as 2.8 mEq/L. Which action should the nurse take?

Cevabı ve açıklamayı göster

Cevap: Withhold the furosemide and report the potassium level to the registered nurse immediately.

Cevap

The correct action is to withhold the furosemide and report the potassium level to the registered nurse immediately.
Furosemide is a potassium-wasting loop diuretic. A serum potassium level of 2.8 mEq/L represents significant hypokalemia, as the normal range is typically 3.5 to 5.0 mEq/L. Administering furosemide would further deplete the client's potassium levels, placing the client at high risk for lethal cardiac dysrhythmias. The practical nurse is acting safely and within their scope of practice by recognizing the dangerous interaction, withholding the medication, and immediately escalating the critical finding to the registered nurse.

Adım Adım Çözüm

1
Analyze the client's laboratory result.
The serum potassium level is 2.8 mEq/L, which indicates significant hypokalemia (normal range is typically 3.5 to 5.0 mEq/L).
Identifying abnormal laboratory values is required before safely administering medications that can affect fluid and electrolyte balance.
2
Evaluate the scheduled medication against the lab finding.
Furosemide is a loop diuretic that causes the kidneys to excrete potassium, which would worsen the client's already low potassium level.
Understanding the pharmacological mechanism of the drug highlights the critical risk of administering it to this specific client.
3
Determine the appropriate nursing intervention within the practical nurse scope of practice.
The practical nurse must withhold the contraindicated medication and escalate the critical finding to the registered nurse.
The practical nurse is responsible for protecting the client from harm and reporting critical data that requires a change in the medical plan of care.

During morning rounds, the practical nurse evaluates an older adult client recovering from a complex pelvic fracture sustained three days ago. The client's family member expresses concern, stating, 'My spouse is acting completely different today and seems very confused.' The nurse notes the client is picking at the bedsheets and appears highly restless. Current vital signs are: temperature 98.8°F (37.1°C), heart rate 112 bpm, respiratory rate 24 breaths/min, blood pressure 106/70 mm Hg, and oxygen saturation 91% on room air. Which actions should the practical nurse implement? (Select all that apply)

Cevap: Auscultate bilateral lung fields and apply supplemental oxygen as prescribed.; Escalate the clinical findings immediately to the supervising registered nurse or healthcare provider.; Review the client's electronic health record for recent hemoglobin, hematocrit, and arterial blood gas results.

Cevap

The correct actions include auscultating the lungs and applying oxygen, notifying the RN or provider immediately, and reviewing recent laboratory results.
The client's sudden onset of confusion, restlessness, tachycardia, tachypnea, and low oxygen saturation in the context of a recent pelvic fracture strongly suggests a life-threatening complication such as fat embolism syndrome or hemorrhage. The practical nurse must prioritize oxygenation (ABCs), immediately escalate the situation to the RN or provider, and gather relevant laboratory data to assist with the ongoing medical evaluation.

Adım Adım Çözüm

1
Analyze the client's presentation and vital signs.
The client exhibits acute confusion, restlessness, tachycardia, tachypnea, and borderline hypoxia.
Identifying abnormal clinical cues is the first step in clinical judgment.
2
Determine the potential underlying physiological complication.
Given the history of a pelvic fracture, the client is at high risk for fat embolism syndrome, hemorrhagic shock, or pulmonary embolism.
Connecting the mechanism of injury to the current symptoms highlights the acuity of the situation.
3
Prioritize interventions based on the ABCs and PN scope of practice.
The immediate needs are oxygenation, escalation of care, and gathering relevant diagnostic data.
Airway and breathing take precedence over all other issues, and acute physiological deterioration requires immediate escalation.

Cevap: Verifying the client's identity using two distinct identifiers before administering prescribed oral analgesics.; Assisting the client to perform turning, coughing, and deep breathing exercises every 2 hours.; Applying prescribed sequential compression devices (SCDs) to the client's lower extremities while resting in bed.

Cevap

The correct actions to reduce risk are verifying the client's identity with two identifiers, assisting with turning and deep breathing, and applying sequential compression devices.
Verifying identity with two identifiers prevents medication errors. Turning, coughing, and deep breathing prevent respiratory complications like atelectasis. Applying sequential compression devices prevents venous thromboembolism. All three are essential interventions to reduce the risk of complications in a postoperative client.

Adım Adım Çözüm

1
Evaluate the interventions aimed at preventing postoperative complications.
Turning, deep breathing, and applying sequential compression devices are recognized strategies to prevent pneumonia and deep vein thrombosis.
Postoperative clients are at high risk for respiratory and circulatory complications due to anesthesia and immobility.
2
Identify safe medication administration practices.
Checking two distinct identifiers is required before administering any medication to prevent errors.
Strict adherence to the rights of medication administration reduces the risk of adverse pharmacological events.
3
Assess the remaining options for unsafe practices or errors in clinical judgment.
Ignoring critical lab values (hemoglobin 7.4 g/dL), dismissing borderline shock signs (tachycardia and hypotension), and accepting IV push delegations are unsafe.
These actions fail to mitigate risks, violate the practical nurse's scope of practice, and could lead to severe client harm.

Anahtar Kavram

The practical nurse reduces risk potential by implementing preventative care measures, adhering to safe medication administration protocols, and promptly escalating abnormal clinical findings.

An older adult client in a rehabilitation center is 48 hours postoperative following a right above-the-knee amputation. When planning basic care to prevent musculoskeletal complications, which positioning strategy should the practical nurse implement?

Cevabı ve açıklamayı göster

Cevap: Assist the client into a prone position for 20 to 30 minutes several times a day.

Cevap

Assist the client into a prone position for 20 to 30 minutes several times a day.
Following an above-the-knee amputation, the client is highly susceptible to developing hip flexion contractures, which can permanently impair their ability to use a prosthesis. Placing the client in a prone position for 20 to 30 minutes three to four times a day fully extends the hip joint, effectively stretching the flexor muscles and preventing contracture formation.

Adım Adım Çözüm

1
Identify the time elapsed since the client's surgery.
The client is 48 hours postoperative.
Positioning protocols for amputation clients change significantly after the first 24 hours to transition from edema control to contracture prevention.
2
Determine the primary musculoskeletal risk for an above-the-knee amputation.
The client is at high risk for developing hip flexion contractures.
Contractures can severely limit mobility and prevent the proper fitting and use of a prosthetic limb.
3
Select the nursing intervention that directly prevents this complication.
Prone positioning stretches the hip flexor muscles.
Lying on the abdomen fully extends the hip joint, counteracting the prolonged flexion that occurs when the client is sitting in a chair or resting in bed.
