Cevabı ve açıklamayı göster

Cevap

The correct priority sequence is to clamp the catheter, position the client in the left lateral Trendelenburg position, administer oxygen, activate the emergency response team, and finally obtain vital signs.
In the event of a disconnected central venous catheter accompanied by sudden respiratory distress, the nurse must suspect an air embolism. The immediate priority is risk reduction by stopping the source of harm. Clamping the catheter prevents more air from entering the heart. Positioning the client on their left side with the head down (Durant's maneuver) traps the air in the right ventricle, preventing it from blocking the pulmonary artery. Oxygen is then applied to treat severe ischemia. Only after these immediate physical stabilization steps are complete should the nurse call for emergency assistance and gather vital signs.

Adım Adım Çözüm

1
Clamp the central venous catheter.
Stops further entrainment of room air into the vascular system.
Air embolism is a mechanical obstruction; stopping the source is always the immediate first step.
2
Place in left lateral Trendelenburg.
Displaces the air away from the right ventricular outflow tract.
Gravity causes the lighter air to rise to the apex of the right ventricle, keeping the pulmonary artery clear for blood flow.
3
Administer oxygen.
Reverses hypoxemia and promotes nitrogen washout.
The client is showing signs of severe respiratory distress due to impaired perfusion.
4
Activate emergency response.
Brings advanced providers and equipment to the bedside.
The client requires critical care, but the nurse must secure the airway and circulation with basic measures first.
5
Assess vital signs.
Provides quantitative data on the client's hemodynamic status.
This establishes a baseline for the arriving code team but is the lowest priority among these emergency actions.

Cevap: Group required assessments and medication administrations together to minimize interruptions.; Dim the overhead lights and close the door partially to decrease external stimuli.; Reorient the client to their surroundings using a calm, unhurried voice.

Cevap

The correct interventions are grouping care tasks, reducing environmental stimuli by dimming lights and closing the door, and providing calm reorientation.
The correct actions directly address sensory overload by reducing environmental stimuli (dimming lights, partially closing the door), minimizing interruptions to promote rest (clustering care), and safely managing the client's altered perception through therapeutic communication (calm reorientation).

Adım Adım Çözüm

1
Analyze the client's presentation and environmental factors.
The client is exhibiting signs of sensory overload and acute delirium due to continuous noise and activity from the nearby nursing station.
Identifying the root cause (excessive environmental stimuli) dictates the appropriate nursing interventions.
2
Evaluate each intervention for safety, scope of practice, and therapeutic value.
Interventions that reduce stimuli (clustering care, dimming lights) and provide safe psychological support (calm reorientation) are selected.
These actions directly mitigate the sensory overload without causing further harm or utilizing restrictive measures.
3
Reject inappropriate or unsafe interventions.
Dismissing the client's fears, normalizing acute confusion, and applying restraints are eliminated.
These actions represent non-therapeutic communication, failure to recognize acute delirium, and premature use of restraints, all of which compromise client safety.

A practical nurse is caring for a client who is 48 hours post-operative following a right above-the-knee amputation. To promote comfort and prevent hip flexion contractures, which position should the nurse encourage the client to assume for 20 to 30 minutes several times a day?

Cevabı ve açıklamayı göster

Cevap: The prone position with the head turned to the side

Cevap

The prone position with the head turned to the side
Placing the client in the prone position for short periods (20 to 30 minutes, 3 to 4 times daily) physically extends the hip joint. This is an essential basic care measure for preventing hip flexion contractures following an above-the-knee amputation, which ensures the client will be able to properly use a prosthesis during rehabilitation.

Adım Adım Çözüm

1
Identify the client's post-operative timeline and surgical procedure.
The client is 48 hours post-above-the-knee amputation.
Nursing care protocols for amputations change significantly after the first 24 hours, specifically regarding limb elevation.
2
Determine the primary complication associated with immobility for this specific surgery.
The highest musculoskeletal risk is the development of a hip flexion contracture.
Contractures limit range of motion and can severely impede or prevent successful prosthetic fitting and rehabilitation.
3
Select the nursing intervention that directly counteracts this risk.
Positioning the client prone.
The prone position fully extends the hip joint, actively preventing the muscles and ligaments from contracting into a flexed position.

The morning laboratory results reveal a serum sodium level of 128 mEq/L128\text{ mEq/L} (128 mmol/L128\text{ mmol/L}). The client is scheduled to receive their routine oral lithium carbonate and oral hydrochlorothiazide in 30 minutes. Current vital signs indicate a heart rate of 115 beats/min115\text{ beats/min} and a blood pressure of 94/58 mm Hg94/58\text{ mm Hg}. Based on the client's clinical presentation, which action is the priority for the practical nurse?

Cevabı ve açıklamayı göster

Cevap: Withhold both medications and immediately notify the registered nurse of the client's laboratory results and vital signs.

Cevap

Withhold both medications and immediately notify the registered nurse of the client's laboratory results and vital signs.
The correct action demonstrates a synthesis of pharmacological knowledge, interpretation of clinical data, and safe practice boundaries. The client's vital signs (tachycardia, hypotension) and history of severe gastrointestinal losses indicate significant fluid volume deficit. Furthermore, the serum sodium level is critically low (128 mEq/L128\text{ mEq/L}). Lithium clearance is directly tied to sodium balance; hyponatremia causes the kidneys to aggressively retain lithium, leading to acute, life-threatening toxicity. Hydrochlorothiazide is a potassium- and sodium-wasting diuretic that would further exacerbate both the hyponatremia and the hypovolemia, compounding the risk of lithium toxicity. The safest and most appropriate action within the practical nurse scope of practice is to withhold both dangerous medications and immediately escalate the critical findings to the registered nurse.

Adım Adım Çözüm

1
Analyze the client's vital signs and clinical presentation.
The client has a history of severe vomiting and diarrhea, a heart rate of 115 beats/min, and a blood pressure of 94/58 mm Hg, indicating significant dehydration and potential hypovolemia.
Recognizing fluid volume deficit is essential before administering any medications that affect fluid balance or renal clearance.
2
Interpret the morning laboratory values.
The serum sodium level is critically low at 128 mEq/L (normal is 135-145 mEq/L).
Electrolyte imbalances directly impact the pharmacokinetics of certain medications, particularly lithium.
3
Evaluate the scheduled medications against the current clinical data.
Hydrochlorothiazide is a diuretic that will worsen the dehydration and hyponatremia. Lithium excretion is heavily dependent on sodium levels; hyponatremia causes the kidneys to reabsorb lithium, leading to rapid toxicity.
Administering either medication under these conditions is strictly contraindicated.
4
Determine the priority nursing action within the practical nurse scope of practice.
The nurse must withhold both medications and immediately escalate the critical findings to the registered nurse or healthcare provider.
The practical nurse has a duty to advocate for client safety by withholding unsafe medications and reporting critical changes in condition to the supervising RN.

Cevap

The correct order requires the PN to first stabilize the client physiologically, obtain the disputed legal documents from the family, escalate the emergency to the provider and charge nurse, place the documents in the medical record for formal review, and finally document the event in the nursing notes.
In acute emergencies complicated by conflicting legal claims, nursing prioritization dictates that physiological stability (Airway/Breathing) is always the first action. Nurses cannot independently interpret disputed legal documents to withhold care. After initiating basic stabilizing measures, the nurse gathers the necessary data (the documents), escalates the issue to the provider who holds the authority to resolve the conflict, ensures the documents are available for review, and completes the nursing documentation last.

Adım Adım Çözüm

1
Maintain the client's airway and apply supplemental oxygen.
Basic physiological safety is maintained during a critical event.
Life preservation supersedes unverified or disputed legal directives. Emergency care cannot be withheld based on verbal claims or unreviewed documents.
2
Request that the family members provide their respective legal documents.
Crucial legal data is gathered directly from the involved parties.
The PN must have the physical documents in hand to accurately report the situation to the healthcare provider.
3
Notify the primary healthcare provider and the charge nurse.
The chain of command and medical decision-makers are activated.
Resolving proxy disputes and officially altering a client's code status requires a provider's assessment and legal/ethics team involvement.
4
Place the documents into the client's medical record.
The advance directives become accessible to the entire interdisciplinary team.
Formal evaluation of the documents by the provider and hospital administration requires them to be part of the official chart.
5
Document the clinical interventions and family statements in the nursing notes.
A complete, factual legal record of the dispute and clinical changes is created.
Thorough documentation protects the nurse and the facility, but is an administrative task that must follow direct client care and escalation.

Which action should the practical nurse take first?

Cevabı ve açıklamayı göster

Cevap: Notify the registered nurse immediately.

Cevap

Notify the registered nurse immediately.
The correct action is to notify the registered nurse immediately. The client's decreasing blood pressure and increasing heart rate, in the context of active bleeding, are classic early indicators of hypovolemic shock. This requires urgent escalation and intervention to restore circulatory volume.

Adım Adım Çözüm

1
Analyze the client's current vital signs compared to their baseline.
The blood pressure has dropped and the heart rate has increased significantly.
Comparing current data to baseline helps identify trends in the client's physiological status.
2
Correlate the vital sign changes with the client's diagnosis.
The client has active gastrointestinal bleeding; the dropping blood pressure and rising heart rate suggest hypovolemic shock.
Recognizing the signs of circulatory compromise is a critical component of physiological adaptation.
3
Determine the highest priority action based on the PN scope of practice.
The most urgent action is to notify the RN or provider to initiate emergent treatment.
In acute emergencies, escalating care is necessary to protect the client's circulation (ABC prioritization).

Cevap

The correct sequence is: cleanse the perineum, begin voiding into the toilet, collect the midstream urine, and finally secure and label the container.
To obtain an uncontaminated midstream clean-catch urine specimen, the urethral meatus must first be cleansed from front to back to remove external bacteria. The client then initiates the urine stream into the toilet to flush the distal urethra of any remaining flora. The sterile container is then introduced into the midstream flow to capture the most representative bladder sample. Finally, the container is sealed to prevent leaks and properly labeled for accurate processing.

A practical nurse is caring for a client who is 36 hours postoperative following a right above-the-knee amputation. The client has a history of dysphagia and is receiving continuous enteral nutrition via a nasogastric tube. The nursing care plan includes interventions to prevent hip flexion contractures. Which action is most appropriate for the practical nurse to implement?

Cevabı ve açıklamayı göster

Cevap: Pause the continuous enteral feeding, wait 30 to 45 minutes, and then assist the client into a flat prone position for 20 to 30 minutes.

Cevap

The most appropriate action is to pause the continuous enteral feeding, wait 30 to 45 minutes, and then assist the client into a flat prone position for 20 to 30 minutes.
The correct action demonstrates safe synthesis of two critical basic care protocols. To prevent hip flexion contractures following an above-the-knee amputation, the client should lie prone for 20 to 30 minutes multiple times a day. However, because the client is receiving continuous enteral feedings, laying them flat immediately poses a severe aspiration risk. The nurse must first pause the feeding and wait 30 to 45 minutes to allow for gastric emptying before safely lowering the head of the bed and turning the client prone.

Adım Adım Çözüm

1
Identify the primary positioning requirement for a client post-above-the-knee amputation.
The client should be placed in a prone position for 20 to 30 minutes several times a day to prevent hip flexion contractures. Elevating the limb on pillows after 24 hours is contraindicated.
Prolonged hip flexion leads to contractures, which can severely impede future prosthesis fitting and mobility.
2
Identify the safety requirements for a client receiving continuous enteral nutrition.
The head of the bed must remain elevated at least 30 to 45 degrees during the feeding and for 30 to 45 minutes after pausing the feeding.
Maintaining elevation prevents regurgitation and aspiration of gastric contents into the lungs.
3
Synthesize the conflicting requirements to determine the safest sequence of actions.
The feeding must be paused and sufficient time allowed for gastric emptying before the client can be safely laid flat for the required prone positioning.
Airway protection (preventing aspiration) takes immediate priority, but contracture prevention must still be implemented safely.

A practical nurse is providing basic care for a client who returned to the medical unit 2 hours ago following an esophagogastroduodenoscopy (EGD) performed with a topical anesthetic throat spray. The client reports feeling hungry, and their family has brought a culturally specific, home-cooked meal. Which of the following actions should the nurse take first?

Cevabı ve açıklamayı göster

Cevap: Verify the return of the client's gag reflex before permitting the consumption of any food or liquids.

Cevap

The nurse must verify the return of the client's gag reflex before allowing any oral intake to prevent aspiration.
Following an EGD with topical throat anesthesia, the client's gag and swallow reflexes are temporarily suppressed. The absolute priority action in basic care is to ensure airway safety by verifying that the gag reflex has fully returned before allowing the client to consume any food or liquids, thereby preventing aspiration.

Adım Adım Çözüm

1
Analyze the client's recent procedure and its physiological effects.
The client received a topical anesthetic throat spray for an EGD.
Local anesthesia to the throat impairs the gag and swallow reflexes, creating a temporary but high risk for aspiration.
2
Evaluate the requested intervention (eating a meal).
The client wants to eat a solid meal brought by the family.
Introducing oral intake before protective airway reflexes have returned can lead to choking or aspiration pneumonia.
3
Determine the priority nursing action based on ABCs (Airway, Breathing, Circulation).
Airway protection is the absolute highest priority.
The nurse must formally assess the return of the gag reflex before permitting any food or liquids, regardless of cultural preferences or the client's current hunger.

While reviewing morning laboratory reports, a practical nurse (PN) notes that a client receiving a daily subcutaneous dose of enoxaparin has a platelet count of 65,000/mm365,000/\text{mm}^3 (65×109/L65 \times 10^9/\text{L}). Which action should the PN take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the enoxaparin and notify the registered nurse of the laboratory results.

Cevap

The practical nurse should withhold the scheduled enoxaparin and notify the registered nurse of the critically low platelet count.
The correct action is to withhold the scheduled medication and immediately notify the registered nurse. Enoxaparin is an anticoagulant that increases the risk of bleeding. A normal platelet count ranges from 150,000150,000 to 400,000/mm3400,000/\text{mm}^3. A count of 65,000/mm365,000/\text{mm}^3 is critically low (thrombocytopenia). Administering an anticoagulant to a client who already has a compromised ability to clot severely increases the risk of spontaneous hemorrhage. The practical nurse must recognize this critical value and intervene to prevent harm.

Adım Adım Çözüm

1
Identify the purpose and physiological risks of the prescribed medication.
Enoxaparin is a low-molecular-weight heparin (anticoagulant) that prevents clot formation and inherently increases the risk of bleeding.
Understanding the medication's mechanism is required to evaluate safety parameters prior to administration.
2
Evaluate the client's laboratory results against normal reference ranges.
The client's platelet count is 65,000/mm365,000/\text{mm}^3, which is significantly below the normal range of 150,000150,000 to 400,000/mm3400,000/\text{mm}^3.
Platelets are essential for normal blood clotting, and low levels (thrombocytopenia) indicate an existing high bleeding risk.
3
Synthesize the findings to determine the appropriate nursing intervention.
Combining an anticoagulant with a critically low platelet count is unsafe. The medication must be withheld and the clinical finding escalated to the registered nurse.
The practical nurse must take immediate, proactive action to reduce the client's risk of severe hemorrhage.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first position the wheelchair on the strong side, lock all brakes, assist the client to a dangling position, apply the transfer belt, and finally have the client pivot using their strong arm.
Safe transfer of a client with hemiplegia requires systematic preparation and execution. First, the environment must be prepared by placing the wheelchair on the client's strong side and locking all wheels. Next, the client's physiological readiness is ensured by allowing them to dangle and stabilize their blood pressure. Then, safety equipment (a transfer belt) is applied before any weight-bearing begins. Finally, the client uses their strong side to pivot and safely lower themselves into the chair.

Adım Adım Çözüm

1
Position the wheelchair on the client's right side.
The equipment is properly aligned on the client's unaffected side.
Transferring toward the strong side allows the client to bear weight and pull themselves safely into the chair.
2
Engage the locking mechanisms on the bed and wheelchair.
Both the bed and the wheelchair are completely immobilized.
This prevents accidental movement of equipment that could lead to unexpected falls.
3
Assist the client to sit on the edge of the bed.
The client is upright with their legs dangling over the side of the mattress.
Promotes equilibrium and prevents a sudden drop in blood pressure (orthostatic hypotension) prior to standing.
4
Apply a transfer belt around the client's waist.
The nurse has a secure and safe point of contact.
Provides a designated handhold to control the client's center of gravity and protect both the client and nurse from injury.

Cevap: Apply a continuous pulse oximeter and verify the patency of the intravenous line.; Position the client flat in bed with the lower extremities elevated.; Immediately report the data collection findings to the supervising registered nurse.

Cevap

The correct actions are to apply continuous pulse oximetry while verifying intravenous access, position the client flat with elevated legs, and immediately report the findings to the registered nurse.
The client is demonstrating classic signs of early compensatory hypovolemic shock, likely secondary to internal hemorrhage following major abdominal surgery. The dangerously narrow pulse pressure (102 - 82 = 20 mm Hg), tachycardia, tachypnea, intense thirst, and restlessness (cerebral hypoperfusion) demand immediate action. The practical nurse must prioritize oxygenation and circulatory support by applying pulse oximetry, ensuring a patent IV line for imminent fluid resuscitation, positioning the client to maximize venous return to vital organs (flat with legs elevated), and immediately escalating the situation to the registered nurse.

Adım Adım Çözüm

1
Analyze the vital signs and physical cues.
The blood pressure of 102/82 mm Hg reveals a narrow pulse pressure of 20 mm Hg. This, combined with tachycardia (118 beats/min), tachypnea, severe thirst, and restlessness, indicates early compensatory hypovolemic shock.
Recognizing subtle signs of shock is required before appropriate interventions can be selected.
2
Evaluate the clinical context of the symptoms.
The client recently underwent major abdominal surgery (partial gastrectomy), making internal hemorrhage the most likely cause of the hypovolemia.
Connecting the surgical history to the vital signs prevents misinterpreting the restlessness as simply postoperative pain or anxiety.
3
Select interventions within the practical nursing scope of practice.
Appropriate actions include promoting venous return (supine with legs elevated), preparing for fluid resuscitation (verifying IV patency), monitoring oxygenation, and rapid escalation to the RN.
The PN must protect airway/breathing/circulation (ABC) and collaborate with the RN for advanced interventions.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to administer a simple carbohydrate, wait 15 minutes, reassess the blood glucose, and finally provide a complex carbohydrate and protein snack.
The standard protocol for treating a conscious client with hypoglycemia is the 'Rule of 15'. The sequence begins with administering 15 grams of a fast-acting simple carbohydrate to rapidly raise the blood glucose. The nurse then waits 15 minutes for the sugar to absorb before reassessing the capillary blood glucose. Once the blood glucose is stabilized above 70 mg/dL, a snack containing a complex carbohydrate and protein is provided to sustain the blood glucose level and prevent a rebound hypoglycemic event.

Adım Adım Çözüm

1
Administer 15 grams of a fast-acting simple carbohydrate.
Provides an immediate source of glucose to treat the hypoglycemia.
The client is symptomatic with a blood glucose of 58 mg/dL; immediate intervention is required to prevent neurological deterioration.
2
Wait 15 minutes to allow the body to absorb the sugar.
Allows time for the simple carbohydrate to enter the bloodstream.
Checking the blood glucose too soon will not accurately reflect the effect of the intervention.
3
Reassess the client's capillary blood glucose level.
Evaluates the effectiveness of the simple carbohydrate administration.
The nurse must verify that the blood glucose has risen to a safe level (typically above 70 mg/dL) or determine if another 15 grams of carbohydrate is needed.
4
Provide a complex carbohydrate and protein snack.
Maintains the blood glucose level.
Simple carbohydrates are metabolized quickly. Providing a complex carbohydrate and protein prevents a subsequent drop in blood sugar.

Cevap: A client 4 hours post-thyroidectomy who is observed frequently swallowing and clearing their throat.; A client receiving a continuous enteral tube feeding who suddenly begins coughing forcefully and expelling frothy sputum.; A client receiving intravenous (IV) furosemide whose morning serum potassium level is 2.8 mEq/L2.8\text{ mEq/L} (2.8 mmol/L2.8\text{ mmol/L}).; A client 2 hours post-cardiac catheterization whose heart rate increases from 78 to 114 beats/minute and blood pressure drops from 122/76 to 96/60 mm Hg.

Cevap

The findings requiring immediate escalation are: the client frequently swallowing post-thyroidectomy, the client forcefully coughing during enteral feeding, the critically low potassium level of 2.8 mEq/L2.8\text{ mEq/L}, and the client developing tachycardia with hypotension post-cardiac catheterization.
Complications that compromise Airway, Breathing, and Circulation (ABCs) or pose an immediate risk to life require immediate escalation. Frequent swallowing post-thyroidectomy is a classic sign of hemorrhage causing hematoma formation and airway compression. Forceful coughing with frothy sputum in a client with an enteral feeding tube strongly suggests displacement into the airway and aspiration. A serum potassium level of 2.8 mEq/L2.8\text{ mEq/L} is critically low (normal 3.5−5.0 mEq/L3.5-5.0\text{ mEq/L}) and can cause fatal cardiac arrhythmias, especially when exacerbated by loop diuretics like furosemide. Finally, a sudden shift toward tachycardia and hypotension following an invasive arterial procedure like a cardiac catheterization is a primary indicator of hemorrhagic shock.

Adım Adım Çözüm

1
Analyze airway and breathing risks in the provided scenarios.
Frequent swallowing post-thyroidectomy indicates internal bleeding pooling in the neck. Coughing with frothy sputum during enteral feeding indicates aspiration. Both require immediate escalation.
Airway compromise is an acute, life-threatening emergency (prioritization of ABCs).
2
Evaluate laboratory values against normal reference ranges.
A potassium level of 2.8 mEq/L2.8\text{ mEq/L} is critically low and requires escalation. A platelet count of 185,000/mm3185,000/\text{mm}^3 is completely normal.
Failure to report critical lab values increases risk potential, while escalating normal values wastes clinical resources.
3
Assess vital signs to distinguish expected postoperative trajectories from hemodynamic instability.
Tachycardia and a dropping blood pressure post-catheterization suggest hemorrhagic shock (escalate). A temperature of 99.4∘F99.4^\circ\text{F} on postoperative day 2 is a normal inflammatory response (do not escalate).
Accurate interpretation of vital sign trends is essential for early recognition of complications.
4
Select all findings that represent acute, life-threatening complications outside the expected recovery trajectory.
The correct selections relate to the thyroidectomy, enteral feeding, potassium level, and cardiac catheterization.
These four scenarios demand immediate RN or provider intervention to mitigate severe risk.

In the presence of a boggy (soft) uterus and heavy vaginal bleeding, the priority nursing action is to firmly but gently massage the fundus. This mechanical stimulation promotes immediate uterine contraction, which compresses the blood vessels at the placental site and controls postpartum hemorrhage caused by uterine atony. This is a primary, life-saving intervention that falls well within the practical nurse's scope of practice.

Adım Adım Çözüm

1
Analyze the client's clinical findings.
The combination of a pad completely saturated in under an hour and a boggy (soft), elevated fundus indicates excessive bleeding caused by uterine atony.
Identifying the physiological source of the bleeding is necessary to select the correct targeted intervention.
2
Determine the priority nursing intervention for uterine atony.
Fundal massage is identified as the immediate first-line action.
Manual stimulation forces the uterine muscles to contract, which mechanically compresses the bleeding blood vessels at the placental detachment site.
3
Evaluate the planned action against the practical nurse (PN) scope of practice.
Fundal massage is an essential, independent nursing action that is safely within the PN scope of practice.
The PN must act immediately to stop the bleeding using within-scope interventions before or while calling for additional registered nurse (RN) or provider assistance.

An older adult client is admitted to a long-term care facility after undergoing a total right hip replacement (posterior approach). When turning and repositioning the client in bed, which action should the practical nurse take?

Cevabı ve açıklamayı göster

Cevap: Keep an abductor wedge or pillow between the client's legs.

Cevap

Keep an abductor wedge or pillow between the client's legs.
Following a posterior total hip replacement, the client's legs must remain abducted to prevent the hip prosthesis from dislocating. Using an abductor wedge or pillow between the legs maintains proper alignment, prevents adduction (crossing the midline), and limits internal rotation while the client is resting or being turned in bed.

Adım Adım Çözüm

1
Identify the surgical procedure and its specific postoperative risks.
The client had a total hip replacement (posterior approach), meaning the primary risk is prosthesis dislocation from adduction, internal rotation, or severe flexion.
Understanding prescribed surgical precautions is necessary to determine safe basic care and positioning.
2
Select the positioning strategy that prevents dislocation.
An abductor pillow keeps the legs separated (abducted) and prevents the operative leg from crossing the midline of the body.
Maintaining proper anatomical alignment ensures joint stability during the healing process.

Cevap

The correct sequence is: 1) Remain with the client and call for immediate assistance, 2) Place the client in a low Fowler's position with the knees flexed, 3) Cover the protruding bowel with sterile, saline-moistened dressings, 4) Measure the client's vital signs, and 5) Document the evisceration event.
In an acute wound evisceration, the primary goal is to prevent further injury and stabilize the client. The practical nurse must first call for help while staying with the client to ensure continuous monitoring. Next, placing the client in a low Fowler's position with flexed knees immediately reduces intra-abdominal pressure. Once supplies arrive, the nurse covers the wound with sterile, moist dressings to preserve tissue viability. Only after the organs are protected from necrosis should the nurse assess vital signs to monitor for shock. Documentation is always the final administrative step, completed once the client is safe.

Adım Adım Çözüm

1
Remain with the client and call for immediate assistance.
Assistance is secured without compromising client safety.
The client must never be left alone during an acute surgical emergency. Calling for help allows others to bring required sterile supplies and notify the provider.
2
Place the client in a low Fowler's position with the knees flexed.
Intra-abdominal pressure is reduced.
This specific positioning relaxes the abdominal muscles, reducing tension on the incision and preventing further protrusion of the internal organs.
3
Cover the protruding bowel with sterile, saline-moistened dressings.
The exposed intestinal tissue is protected.
Exposed bowel can quickly dry out, leading to tissue necrosis. Sterile, moist dressings preserve the tissue and reduce the risk of severe infection.
4
Measure the client's vital signs to assess for shock.
The client's hemodynamic status is evaluated.
Evisceration can precipitate hypovolemic shock. Once the physical site is protected, assessing vital signs guides further emergency medical interventions.
5
Document the evisceration event and the nursing interventions provided.
An accurate medical record is maintained.
Administrative tasks and documentation must always occur after the client is physically stabilized and the immediate life threat is managed.

Anahtar Kavram

Prioritization of nursing care during wound evisceration requires immediate protection of the client, reduction of abdominal tension, and preservation of the exposed organs, followed by physiological monitoring.

Cevap: Roll the client toward the unaffected side with an abduction wedge securely in place between the legs to wash the back.; Place a fracture pan under the buttocks while the client uses an overhead trapeze bar to assist with lifting.; Wash the client's eyes from the inner canthus to the outer canthus, using a different section of the washcloth for each wipe.

Cevap

The appropriate actions are to roll the client toward the unaffected side with an abduction wedge, use a fracture pan combined with an overhead trapeze bar, and wash the eyes from the inner to the outer canthus.
The appropriate actions prioritize joint safety, airway management, and infection control. Using an abduction wedge when turning to the unaffected side prevents dangerous hip adduction. Utilizing a fracture pan with a trapeze bar minimizes hip flexion during elimination. Finally, washing the eyes from the inner to outer canthus adheres to standard hygiene principles to prevent eye infections.

Adım Adım Çözüm

1
Identify the client's specific physical limitations and safety requirements.
The client is 2 days postoperative for a right total hip arthroplasty (posterior approach) and requires strict adherence to precautions: no hip flexion greater than 90 degrees, no adduction, and no internal rotation.
Understanding surgical precautions is essential before initiating any physical movement or basic care.
2
Evaluate positioning techniques for hygiene tasks.
Rolling the client toward the unaffected side while utilizing an abduction wedge prevents adduction and internal rotation, making it a safe method to wash the back.
Maintaining neutral alignment of the operative leg prevents dislocation of the new hip joint.
3
Determine the safest method for assisting with elimination.
Utilizing a fracture pan requires less lifting, and having the client use an overhead trapeze bar allows them to raise their torso without excessive hip flexion.
A standard bedpan usually requires significant hip flexion and rolling, which violates posterior hip precautions.
4
Recall standard infection control principles for facial hygiene.
Washing the eyes from the inner canthus to the outer canthus using clean sections of the cloth is identified as the correct protocol.
This specific technique prevents the introduction of bacteria or debris into the lacrimal ducts.
5
Identify and exclude contraindicated or unsafe actions.
Flexing the hip to 110 degrees, feeding the client while completely flat, and immediately applying restraints are all rejected.
Hip flexion past 90 degrees violates orthopedic precautions, feeding while flat prioritizes joint precautions over immediate airway safety (aspiration risk), and applying restraints without alternatives violates safety protocols.

Cevap

The correct sequence is to first position the client in the left lateral Sims position, then lubricate the tip of the tubing, gently insert the tubing into the rectum, and finally open the clamp to allow the solution to flow.
The correct sequential order for administering an enema ensures client safety, promotes comfort, and maximizes the procedure's efficacy. Positioning the client properly in the left lateral Sims position must always come first to physically prepare the client and utilize gravity for the bowel's anatomical curve. Next, lubricating the tube is an essential safety measure that must be completed immediately before any contact is made with the body to prevent mucosal damage. After lubrication, the tube is safely and gently inserted 3 to 4 inches into the rectum. Finally, only once the tube is correctly placed and secured by the nurse's hand, the clamp is opened to begin the instillation of the fluid.

Adım Adım Çözüm

1
Assist the client into the left lateral Sims position.
The client is positioned appropriately for the procedure.
This position follows the natural curve of the descending colon and sigmoid colon, utilizing gravity to help the fluid flow inward.
2
Apply a water-soluble lubricant to the tip of the enema tubing.
The tubing tip is slick and ready for insertion.
Lubrication is essential to reduce friction and prevent trauma or tearing of the delicate rectal mucosa during insertion.
3
Gently insert the tubing 3 to 4 inches (7.5 to 10 cm) into the client's rectum.
The tube is placed at the correct depth within the rectum.
Proper insertion depth ensures the fluid is delivered past the internal and external sphincters without causing injury or perforation.
4
Open the clamp on the tubing and allow the solution to flow slowly.
The enema solution begins to instill into the colon.
Opening the clamp initiates the actual treatment. Flowing the fluid slowly prevents sudden bowel distension, which can cause severe cramping.
