Cevap

The correct sequence prioritizes securing immediate help, reducing physical strain on the wound, protecting the exposed tissue, assessing hemodynamic stability, and preparing for definitive surgical repair.
Wound evisceration is a medical emergency requiring rapid, sequential actions to protect the exposed bowel and stabilize the client. The immediate priority is to get help without leaving the client. Next, mechanical tension on the abdomen must be reduced by flexing the client's knees and elevating the head slightly. After reducing tension, the exposed organs are covered with sterile, moist dressings to prevent necrosis. Once the tissue is protected, assessing vital signs for shock becomes the priority before ultimately preparing the client for emergency surgical repair.

Adım Adım Çözüm

1
Secure help and escalate.
Additional personnel are mobilized to notify the provider and gather supplies.
The primary nurse must not leave the bedside of a client experiencing an acute evisceration.
2
Modify the client's position to low-Fowler's with flexed knees.
Intra-abdominal pressure is significantly reduced.
This prevents further loops of bowel from protruding through the separated incision.
3
Cover the viscera with sterile, saline-moistened dressings.
The exposed bowel is kept moist and protected from environmental contaminants.
Preserves tissue viability and prevents necrosis prior to surgical intervention.
4
Assess a full set of vital signs.
Baseline data during the emergency is established.
Allows for the early identification of hypovolemic shock resulting from fluid shifts and stress.
5
Initiate preoperative preparation protocols.
The client is ready for rapid transport.
Evisceration is a surgical emergency requiring immediate closure in the operating room.

A client who underwent a total hip arthroplasty 24 hours ago is found pulling at their intravenous tubing. The client, who was fully oriented during the morning assessment, is now highly restless and disoriented to place. The current heart rate is 112 beats per minute and the respiratory rate is 26 breaths per minute. What is the priority action for the practical nurse in this situation?

Cevabı ve açıklamayı göster

Cevap: Obtain a pulse oximetry reading and immediately evaluate the client's respiratory status.

Cevap

The priority action is to evaluate the client's respiratory status by obtaining a pulse oximetry reading and assessing the airway and breathing.
Sudden onset of restlessness, agitation, and confusion, particularly when accompanied by tachypnea and tachycardia, are classic early indicators of hypoxia. Because this client is 24 hours post-hip arthroplasty, they are at high risk for a pulmonary embolism or fat embolism. The nurse must prioritize the 'Airway and Breathing' components of the ABC framework by immediately evaluating the client's oxygenation status before considering other interventions.

Adım Adım Çözüm

1
Analyze the clinical cues presented by the client.
The client exhibits sudden restlessness, disorientation, tachycardia, and tachypnea 24 hours post-surgery.
Identifying acute deviations from a client's baseline is the first step in clinical reasoning and recognizing complications.
2
Determine the most life-threatening potential cause for these new symptoms.
Sudden agitation and confusion, accompanied by increased heart and respiratory rates, are hallmark early signs of hypoxia (such as from a pulmonary embolism or fat embolism).
Prioritization requires addressing airway, breathing, and circulation (ABC) before considering secondary psychological or environmental concerns.
3
Select the intervention that directly addresses the highest priority need.
Assessing oxygenation status is the immediate priority to rule out or confirm a life-threatening respiratory compromise.
Nursing interventions must follow the ABC framework; assessing respiratory function takes precedence over administering sedatives or performing routine documentation.

A practical nurse (PN) is assisting a client with ambulation in the hallway using a gait belt. The client suddenly reports feeling dizzy, their knees buckle, and they begin to fall. Arrange the following actions the PN should take in the correct chronological order to safely assist the client to the floor.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to establish a base of support, bring the client close, extend a leg for the client to slide down, lower them by bending the knees while protecting the head, and then call for help to assess for injuries.
When a client begins to fall during ambulation, the nurse's priority is to perform a controlled 'assisted fall' to minimize injury. The sequence must begin with the nurse establishing their own stability by taking a wide stance. Next, bringing the client close to the nurse's center of gravity provides control over the descending weight. Extending a leg creates a safe slide path, preventing a rapid drop. Bending at the knees ensures the nurse uses strong leg muscles rather than straining the back, while the nurse actively protects the client's head from impact. Finally, once safely on the floor, the client must remain stationary until a thorough assessment is completed to prevent exacerbating any potential injuries.

Adım Adım Çözüm

1
Establish stability.
The nurse takes a wide stance with feet apart.
Creates a broad base of support to prevent the nurse from losing balance when taking on the client's weight.
2
Control the client's weight.
The client is pulled close to the nurse using the gait belt.
Aligns the client with the nurse's center of gravity, providing maximum control and reducing back strain.
3
Create a descent path.
The nurse extends one leg forward.
Provides a physical surface for the client to safely slide down rather than free-falling.
4
Lower the client to the floor.
The nurse bends at the knees and protects the client's head.
Uses strong leg muscles (proper body mechanics) and prevents traumatic head injury upon contact with the floor.
5
Manage post-fall care.
The client is instructed to stay still while the nurse calls for assistance.
Moving a client immediately after a fall can worsen undetected fractures or internal injuries.

A client with progressive dementia resides in a subacute rehabilitation facility and is scheduled for the surgical placement of a percutaneous endoscopic gastrostomy (PEG) tube. The healthcare provider discussed the procedure with the client's legally designated healthcare proxy the previous day. The proxy arrives at the facility to sign the consent form. As the practical nurse (PN) presents the document, the proxy asks, "I know the doctor explained it yesterday, but could you quickly remind me of the alternative options if we decline the feeding tube?" Which action should the PN take?

Cevabı ve açıklamayı göster

Cevap: Withhold the consent form and contact the healthcare provider to address the proxy's questions.

Cevap

Withhold the consent form and contact the healthcare provider to address the proxy's questions.
The practical nurse's legal role in informed consent is to witness the signature, confirm the client or proxy is competent, and verify that consent is voluntary. Explaining the procedure, its risks, benefits, and any alternative treatments is solely the responsibility of the healthcare provider. Because the proxy expressed a need for clarification regarding alternatives, the nurse must withhold the consent form and notify the provider to answer these questions before the signature is obtained.

Adım Adım Çözüm

1
Identify the practical nurse's legal role in the informed consent process.
The nurse's role is strictly to act as a witness to the signature, verify the person signing is competent, and ensure consent is given voluntarily.
This establishes the legal boundaries of the nursing scope of practice.
2
Evaluate the healthcare proxy's statement.
The proxy is asking for clarification regarding alternative medical options to the PEG tube.
Determining the nature of the proxy's question indicates whether valid informed consent has been achieved.
3
Determine the appropriate intervention based on scope of practice.
Because explaining risks, benefits, and alternatives is exclusively the healthcare provider's responsibility, the nurse must halt the consent process and notify the provider.
Answering medical questions about alternatives falls outside the nursing scope of practice, and valid consent cannot be obtained until the provider directly answers the proxy's questions.

Anahtar Kavram

The practical nurse's role in informed consent is limited to witnessing the signature and verifying voluntary agreement; any questions about the procedure, risks, or alternatives must be directed to the healthcare provider.

A practical nurse (PN) has finished providing morning care and changing the bed linens for a client diagnosed with both *Rubella* and *Norovirus*. As the PN prepares to leave the isolation room, which sequence of actions is correct?

Cevabı ve açıklamayı göster

Cevap: Remove the gloves and gown inside the client's room, exit the room, remove the surgical mask, and immediately wash hands with soap and water.

Cevap

The correct sequence is to remove the gloves and gown inside the client's room, exit the room, remove the surgical mask, and then immediately wash hands with soap and water.
The client requires Contact Precautions for *Norovirus* and Droplet Precautions for *Rubella*. To prevent cross-contamination, contact personal protective equipment (gown and gloves) must be removed inside the patient's room. Droplet protective equipment (the surgical mask) should be removed after exiting the room. Because *Norovirus* is an enteric pathogen that is resistant to alcohol-based hand rubs, hand hygiene must be performed using soap and water rather than sanitizer.

Adım Adım Çözüm

1
Identify the transmission-based precautions required for the specific pathogens.
*Norovirus* requires Contact Precautions with enhanced enteric hand hygiene. *Rubella* requires Droplet Precautions.
Pathogen-specific protocols dictate the type of personal protective equipment (PPE) worn and the exact method of hand hygiene required.
2
Determine the correct location for removing Contact Precaution PPE (gown and gloves).
Gowns and gloves must be removed inside the client's room before exiting.
Removing contaminated contact PPE outside the room spreads pathogens to the clean hallway environment.
3
Determine the correct location for removing Droplet Precaution PPE (surgical mask).
The surgical mask must be removed after exiting the client's room and closing the door.
Removing the mask inside the room exposes the nurse's respiratory tract to airborne droplets still suspended in the patient's immediate environment.
4
Select the appropriate hand hygiene method based on the pathogens present.
Hands must be washed with soap and water.
Alcohol-based hand rubs lack efficacy against non-enveloped enteric viruses like *Norovirus*. Mechanical friction with soap and water is required to physically remove the viral particles from the skin.

A medical-surgical unit is at maximum capacity, requiring some clients on transmission-based precautions to be cohorted in semi-private rooms. When reviewing the bed assignment board, which client pairing should the practical nurse (PN) recognize as a safe and appropriate cohorting strategy?

Cevabı ve açıklamayı göster

Cevap: A client with a vancomycin-resistant Enterococcus (VRE) infected surgical wound sharing a room with a client who has a VRE urinary tract infection.

Cevap

The safe and appropriate cohorting strategy is to pair the client with the VRE infected wound with the client who has a VRE urinary tract infection.
Cohorting is the practice of grouping clients with the same specific active infection. Because both clients in this pairing are infected with vancomycin-resistant Enterococcus (VRE), they can safely share a room without the risk of cross-infecting each other with a new, different pathogen. Both require contact precautions, and standard infection control measures must still be maintained between the clients.

Adım Adım Çözüm

1
Identify the core principles of cohorting clients with infectious diseases in a shared room.
Clients should ideally be placed in private rooms. If unavailable, they may share a room only if they are confirmed to be infected with the exact same microorganism.
This prevents cross-contamination and the introduction of new, harmful pathogens to already vulnerable clients.
2
Evaluate each pairing to determine if the pathogens match or if a vulnerable client is placed at risk.
Only the pairing with VRE involves the exact same pathogen. The C. diff/rotavirus pairing and the TB/measles pairing involve different pathogens. The neutropenia/pneumonia pairing places an immunocompromised client in danger.
Matching the isolation category or symptom profile is insufficient; the specific causative organism must be identical for safe cohorting.

Cevap: Withhold the scheduled theophylline dose and immediately notify the registered nurse (RN) of the clinical findings.

Cevap

The most appropriate action is to withhold the scheduled theophylline dose and immediately notify the registered nurse (RN) of the clinical findings.
The correct action demonstrates an understanding of theophylline's narrow therapeutic index (10−20 mcg/mL10-20\text{ mcg/mL}) and the interaction with ciprofloxacin, which inhibits its metabolism. The client's level of 23 mcg/mL23\text{ mcg/mL}, combined with symptoms of restlessness, nausea, and tachycardia, clearly indicates toxicity. To prevent life-threatening complications like seizures and ventricular arrhythmias, the PN must withhold the dose and promptly escalate the findings to the RN.

1
Analyze the client's reported symptoms and laboratory data.
The client reports tingling in the lips and fingers (paresthesia), and has a serum calcium level of 7.2 mg/dL, indicating acute and severe hypocalcemia.
Thyroidectomy carries a high risk of inadvertent parathyroid gland removal or damage, which abruptly disrupts calcium regulation.
2
Evaluate the current vital signs for additional signs of physiological instability.
The heart rate of 108 beats/min and blood pressure of 102/64 mm Hg are borderline vital signs indicating potential compensatory mechanisms.
Severe hypocalcemia severely impairs cardiac contractility, and postoperative bleeding into the neck is a concurrent risk requiring vigilant monitoring.
3
Determine the appropriate, safe nursing intervention within the practical nurse scope of practice.
The immediate and safest action is to escalate the findings to the supervising registered nurse.
The practical nurse must recognize impending life-threatening complications (such as tetany or laryngospasm) and coordinate care, as correcting severe hypocalcemia requires RN or provider-level interventions.

Cevabı ve açıklamayı göster

Cevap

First, stop the enteral feeding pump. Second, place the client in a high-Fowler's or side-lying position. Third, auscultate lung sounds and measure oxygen saturation. Fourth, report the condition to the registered nurse (RN). Finally, document the event.
When a client receiving an enteral feeding exhibits signs of respiratory distress such as a severe coughing spell and tachypnea, pulmonary aspiration is the primary concern. According to the Airway, Breathing, Circulation (ABC) priority framework, the absolute first step is to remove the immediate threat to the airway by pausing the feeding pump. Next, the airway must be mechanically protected by positioning the client upright or on their side. After the airway is physically safeguarded, the PN collects targeted data (lung sounds, oxygen saturation) to assess the severity of the breathing compromise. This critical data is then rapidly communicated to the RN or provider for advanced medical interventions. Documentation is strictly performed last, once the client is safe and the broader care team is engaged.

Adım Adım Çözüm

1
Stop the continuous enteral feeding pump.
The flow of enteral formula is halted immediately.
Continuing the feeding while the client is coughing and tachypneic heavily increases the risk of massive pulmonary aspiration.
2
Place the client in a high-Fowler's or side-lying position.
The client's airway is physically protected.
An upright or side-lying position utilizes gravity to keep residual gastric contents from traveling up the esophagus and allows for maximum lung expansion.
3
Auscultate lung sounds and measure the client's oxygen saturation.
Quantitative and qualitative respiratory data are obtained.
The PN must collect targeted data to evaluate the degree of physiological adaptation and respiratory compromise before calling for help.
4
Report the sudden change in condition to the registered nurse (RN).
The healthcare team is alerted to the adverse event.
The PN operates under the direction of an RN or provider and must communicate critical changes so advanced interventions can be prescribed.
5
Document the clinical event, vital signs, and nursing interventions.
A legal and clinical record of the emergency is created.
Documentation must reflect the exact sequence of events, but it is strictly performed after the client is safe and handoff is complete.

A client receiving a continuous intravenous infusion of 0.9% sodium chloride for dehydration suddenly develops a bounding pulse, jugular venous distention, and a new onset of dyspnea. Auscultation reveals crackles in the bilateral lung bases. Which immediate action should the practical nurse take?

Cevabı ve açıklamayı göster

Cevap: Halt the intravenous infusion and position the client upright.

Cevap

The practical nurse should immediately halt the intravenous infusion and position the client upright to address the acute fluid volume overload.
The client is exhibiting classic signs of fluid volume overload, likely due to the continuous intravenous infusion. The priority is to address Airway, Breathing, and Circulation (ABCs). Stopping the infusion prevents further fluid accumulation, and positioning the client upright (e.g., high Fowler's position) decreases venous return and maximizes lung expansion, thereby improving oxygenation. These are critical, immediate actions that fall within the practical nurse's scope of practice before escalating the situation to the registered nurse.

Adım Adım Çözüm

1
Analyze the clinical presentation.
The client has a bounding pulse, jugular venous distention, dyspnea, and lung crackles.
Identifying the pattern of symptoms is necessary to determine the underlying complication.
2
Identify the complication.
These symptoms indicate fluid volume overload (pulmonary edema) caused by the continuous intravenous infusion.
Connecting the intravenous therapy to the new symptoms establishes the cause of the acute respiratory distress.
3
Determine the priority nursing action within the PN scope of practice.
The immediate priorities are to stop the source of the excess fluid (the infusion) and improve respiratory mechanics (upright positioning).
These actions directly address the ABCs (Airway, Breathing, Circulation) and prevent further deterioration while awaiting RN or provider intervention.

Cevabı ve açıklamayı göster

Cevap: A client who had abdominal surgery 4 hours ago with a resting heart rate of 112 beats/min and a blood pressure of 96/60 mm Hg.; A client receiving daily furosemide whose morning serum potassium level is 3.1 mEq/L (3.1 mmol/L).; A client who had a thoracentesis 1 hour ago reporting sudden, sharp chest pain and new-onset tachypnea.; A client scheduled for a contrast-enhanced computed tomography (CT) scan whose morning serum creatinine level is 2.4 mg/dL (212 µmol/L).

Cevap

The findings requiring immediate escalation include the postoperative client with tachycardia and borderline hypotension, the client with a potassium level of 3.1 mEq/L, the post-thoracentesis client with sudden chest pain, and the client scheduled for a contrast CT scan with an elevated creatinine level.
The correct findings all represent acute safety risks that fall outside expected parameters. A heart rate of 112 beats/min with a blood pressure of 96/60 mm Hg in a postoperative client indicates early hypovolemic shock or hemorrhage. A potassium level of 3.1 mEq/L is critically low (normal 3.5-5.0 mEq/L) and risks life-threatening arrhythmias, especially with loop diuretic use. Sudden chest pain and tachypnea after a thoracentesis are classic signs of a pneumothorax. An elevated creatinine level (normal 0.6-1.2 mg/dL) indicates renal impairment, placing the client at high risk for acute kidney injury if intravenous contrast dye is administered.

Adım Adım Çözüm

1
Analyze each client finding to differentiate between expected baseline outcomes and signs of physiological instability.
Identified that post-surgical pain and stable vital signs on a beta-blocker are expected, benign findings.
Prioritization requires distinguishing normal therapeutic responses from acute threats.
2
Evaluate the laboratory values against normal reference ranges.
Identified that a potassium level of 3.1 mEq/L is critically low and a creatinine level of 2.4 mg/dL is abnormally high.
Recognizing critical laboratory values prevents adverse events such as dysrhythmias and nephrotoxicity.
3
Assess the post-procedure findings for signs of life-threatening complications.
Recognized that tachycardia/hypotension post-abdominal surgery indicates shock, and sudden chest pain post-thoracentesis indicates a pneumothorax.
Early recognition of shock and organ compromise allows for rapid medical intervention and prevents mortality.

Cevap

The correct sequence for changing an ostomy pouch is: 1) Remove the used pouch and skin barrier, 2) Cleanse the stoma and peristomal skin with warm water and pat dry, 3) Measure the stoma, 4) Cut the opening on the new skin barrier 1/8 inch larger than the stoma, and 5) Apply the new skin barrier and pouch.
The correct sequence ensures patient comfort, skin protection, and appliance adherence. First, the old pouch must be gently removed to avoid skin trauma. Next, the area is cleansed with warm water (avoiding soaps that leave residue) and dried completely to prepare the skin. Once clean, the stoma is measured accurately, as sizes can fluctuate. The new wafer is then cut 1/8 inch larger than the measurement to prevent stomal constriction while protecting the peristomal skin. Finally, the new appliance is applied and sealed with gentle pressure.

Adım Adım Çözüm

1
Remove the used pouch and skin barrier.
The old appliance is safely detached from the skin.
This allows access to the stoma and peristomal skin for assessment and cleaning. Gentle removal prevents skin tears.
2
Cleanse the stoma and peristomal skin with warm tap water and pat dry.
The skin is free of effluent and moisture.
Thorough cleaning prevents infection and skin breakdown. Avoiding soap prevents leaving a residue that impairs adhesion. Drying is critical for the new wafer to stick.
3
Measure the stoma using a measuring guide.
The exact current size of the stoma is determined.
Stomas can swell or shrink. An accurate measurement ensures the new barrier will fit correctly without exposing skin or strangulating the stoma.
4
Cut the opening on the new skin barrier 1/8 inch larger than the stoma.
A custom-sized opening is created in the barrier.
Leaving a 1/8-inch margin prevents the rigid edge of the wafer from rubbing against and cutting the stoma, while still protecting the peristomal skin from fecal contact.
5
Center the new barrier over the stoma and apply pressure.
The new pouching system is securely attached.
Proper alignment and pressure activate the adhesive and create a seal, preventing leaks.

Anahtar Kavram

Proper ostomy care requires a sequential approach focused on protecting peristomal skin integrity and ensuring a secure appliance seal.
