Cevap: Administering a scheduled continuous enteral tube feeding to a client with a history of dysphagia; Performing a routine sterile dressing change for a client with a healing midline abdominal incision; Inserting a prescribed indwelling urinary catheter for a client experiencing postoperative urinary retention

Cevap

The practical nurse (PN) can safely administer continuous enteral tube feedings, perform sterile dressing changes, and insert indwelling urinary catheters.
The correct selections represent tasks that are firmly within the legal scope of practice for a practical nurse (PN). PNs are qualified to care for stable clients with predictable outcomes. This includes administering scheduled enteral tube feedings, performing sterile procedures such as routine dressing changes on healing incisions, and inserting indwelling urinary catheters. These tasks rely on established protocols and do not require the comprehensive assessment, initial teaching, or independent clinical judgment that are exclusive to the registered nurse (RN).

Adım Adım Çözüm

1
Identify the client care tasks that fall within the legal scope of practice for a practical nurse (PN).
Enteral feedings, sterile dressings, and catheterizations are recognized as standard PN skills.
PNs are educated and licensed to perform these stable, predictable procedures for clients whose conditions are not critical or highly complex.
2
Identify tasks that require the advanced knowledge, assessment skills, or teaching capabilities of a registered nurse (RN) or healthcare provider.
Initial teaching, evaluation of IV push medications, and explaining surgical risks are outside the PN scope.
These tasks require comprehensive assessment, advanced clinical judgment, or fall strictly under the provider's legal duty for informed consent.

An LPN/LVN is caring for a 76-year-old client who is two days postoperative following a total hip arthroplasty. The client, who was previously alert and oriented, suddenly becomes agitated, disoriented, and attempts to climb out of bed. Which of the following is the priority action for the LPN/LVN to take?

Cevabı ve açıklamayı göster

Cevap: Obtain a complete set of vital signs, including oxygen saturation, and report the findings to the registered nurse.

Cevap

Obtain a complete set of vital signs, including oxygen saturation, and report the findings to the registered nurse.
Sudden onset of confusion, agitation, or delirium in an older adult, especially postoperatively, is often an early sign of a physiological problem such as hypoxia, infection, or hemorrhage. Obtaining a full set of vital signs, including oxygen saturation, prioritizes the Airway, Breathing, and Circulation (ABC) framework. It provides essential objective data to identify or rule out life-threatening conditions, which must then be immediately reported to the registered nurse for further clinical judgment.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
An older adult client is exhibiting sudden onset agitation and confusion two days after major joint surgery.
Recognizing an acute change in baseline mental status is the critical first step in the clinical judgment process.
2
Apply prioritization frameworks (ABCs and the Nursing Process).
Assessment (gathering vital signs) must precede intervention (medication or restraints), and physiological needs (oxygenation/perfusion) take priority over assumed discomfort.
Sudden confusion is a classic early sign of hypoxia or shock in postoperative clients, which are life-threatening if missed.
3
Select the action that addresses the highest priority physiological need within the LPN/LVN scope.
Obtaining vital signs provides objective data to rule out hypoxia and other acute physiological changes, which can then be escalated.
This action directly aligns with reducing risk potential by identifying clinical deterioration early and safely.

A practical nurse (PN) is assisting a client with collecting a sputum specimen for culture and sensitivity. To ensure an accurate diagnostic sample and reduce the risk of sample contamination, in what order should the PN instruct the client to perform these steps?

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence for collecting a sputum specimen is: rinse the mouth, take deep breaths and cough, expectorate into the sterile cup, secure the lid, and place in a biohazard transport bag.
To obtain an accurate sputum culture and prevent contamination, the client must first rinse with plain water to clear resident oral flora. Next, taking deep breaths and coughing helps bring up lower respiratory secretions. The sputum is then expectorated directly into a sterile cup, which is sealed carefully to maintain sterility. Finally, it is placed in a biohazard bag to prevent transmission of infectious agents during transport.

A practical nurse (PN) is collecting data on a client who underwent a percutaneous liver biopsy 4 hours ago. The client's baseline vital signs were blood pressure 130/82 mm Hg and heart rate 72 beats/minute. Which current assessment finding presents the highest risk for a severe complication and requires immediate escalation to the registered nurse (RN)?

Cevabı ve açıklamayı göster

Cevap: A gradual increase in heart rate to 108 beats/minute and a blood pressure of 102/66 mm Hg

Cevap

A gradual increase in heart rate to 108 beats/minute and a blood pressure of 102/66 mm Hg
The liver is highly vascular, placing the client at significant risk for internal hemorrhage following a percutaneous biopsy. A narrowing pulse pressure, a drop in systolic blood pressure, and a compensatory increase in heart rate are classic early signs of hypovolemic shock. This finding requires immediate escalation to the RN for intervention.

Adım Adım Çözüm

1
Identify the client's procedure and associated risks.
The client had a percutaneous liver biopsy, which carries a high risk for internal hemorrhage due to the liver's vascularity.
Recognizing high-risk procedures guides targeted post-procedure assessments.
2
Compare current vital signs to the established baseline.
The heart rate increased significantly from 72 to 108 beats/minute, and blood pressure dropped from 130/82 to 102/66 mm Hg.
Trend analysis is crucial for detecting subtle, early signs of physiological decline such as shock.
3
Evaluate the remaining findings for severity.
Right shoulder pain is an expected referred pain (phrenic nerve irritation), the hemoglobin is normal, and asking about risks is a non-emergent teaching need.
Prioritization requires differentiating between expected findings, stable data, and life-threatening crises.
4
Select the finding that indicates a life-threatening complication.
The changes in vital signs indicate early hypovolemic shock from internal bleeding.
Internal hemorrhage is an airway, breathing, or circulation (ABC) priority that requires immediate RN and provider intervention.

Cevap: Verifying that the client is signing the consent document voluntarily and without coercion.; Witnessing the signature to confirm the identity of the person signing the document.; Notifying the registered nurse (RN) or surgeon if the client expresses confusion about the planned procedure.

Cevap

The practical nurse's actions should include verifying voluntary consent, witnessing the client's signature, and notifying the RN or provider if the client exhibits any lack of understanding.
In the informed consent process, the practical nurse's role is strictly limited to advocating for the client and witnessing the signature. This involves verifying that the client is the actual person signing, ensuring the signature is given voluntarily without coercion, and confirming that the client has no further questions. If the client expresses confusion or asks new questions about the procedure's risks, the PN must pause the process and notify the registered nurse or provider.

Adım Adım Çözüm

1
Analyze the requested role of the practical nurse (PN) regarding the informed consent document.
The PN acts as a client advocate and a legal witness, but is not the primary provider of procedural or medical information.
Understanding professional scope of practice ensures legal and safe client care.
2
Evaluate each option against the PN's legal scope of practice.
Verifying voluntariness, witnessing the signature, and escalating client confusion are within the PN's scope. Explaining surgical risks and assessing legal competency are out of scope.
The provider must explain the procedure details, and evaluating cognitive competency requires RN or provider-level assessment.

A practical nurse (PN) has finished providing care for a client diagnosed with varicella. The client is placed in a negative-pressure isolation room, and the PN is currently wearing an N95 respirator, an isolation gown, and gloves. Which of the following describes the correct procedure for removing the personal protective equipment (PPE)?

Cevabı ve açıklamayı göster

Cevap: Remove the isolation gown and gloves inside the client's room, and remove the N95 respirator after exiting the room and closing the door.

Cevap

The correct procedure is to remove the isolation gown and gloves inside the client's room, and remove the N95 respirator after exiting the room and closing the door.
Varicella requires both airborne and contact precautions. To prevent environmental cross-contamination, the PPE used for contact precautions (the gown and gloves) must be removed inside the client's room prior to leaving. To protect the healthcare worker from airborne particles, the N95 respirator must remain securely in place until the nurse has exited the negative-pressure room and the door is completely closed.

Adım Adım Çözüm

1
Identify the required isolation precautions for a client diagnosed with varicella (chickenpox).
Varicella requires a combination of both airborne and contact precautions.
The virus is transmitted through airborne infectious droplet nuclei as well as direct contact with skin lesions.
2
Determine the proper location for removing contact precaution PPE (the isolation gown and gloves).
Gowns and gloves must be removed inside the client's room before exiting.
Removing contact PPE inside the room prevents the spread of pathogens from the contaminated garments to the external hospital environment.
3
Determine the proper location for removing airborne precaution PPE (the N95 respirator).
The N95 respirator must remain on until the nurse has exited the room and the door is completely closed.
Airborne droplet nuclei can remain suspended in the air of the negative-pressure room. Removing the respirator inside would expose the nurse to these particles.

An older adult client with a history of chronic obstructive pulmonary disease (COPD) and heart failure is receiving a continuous intravenous infusion of 0.9% sodium chloride. The practical nurse is preparing to administer scheduled morning medications, which include oral levofloxacin, oral furosemide, and subcutaneous enoxaparin. During the pre-administration assessment, the client appears restless. Vital signs are: heart rate 112 beats/min, blood pressure 90/58 mm Hg, and oxygen saturation 88% on 2 L/min via nasal cannula. The morning laboratory report shows a platelet count of 95,000/mm³ (95×10995 \times 10^9/L). Based on these findings, which action should the practical nurse take first?

Cevabı ve açıklamayı göster

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

Cevap

The correct action is to withhold all scheduled medications and immediately notify the registered nurse of the assessment findings and laboratory results.
The client is experiencing acute clinical deterioration evidenced by restlessness, tachycardia, hypotension, and hypoxia, alongside a critical laboratory finding (thrombocytopenia). Administering furosemide will exacerbate the hypotension, and enoxaparin poses a severe bleeding risk due to the low platelets. The practical nurse must recognize this complex, unstable presentation, withhold the potentially dangerous pharmacological therapies, and immediately report the findings to the registered nurse for urgent collaborative intervention.

Adım Adım Çözüm

1
Analyze the client's vital signs and clinical presentation.
The client is restless with tachycardia (112 beats/min), borderline hypotension (90/58 mm Hg), and hypoxia (88%), indicating acute hemodynamic and respiratory deterioration.
Recognizing signs of acute decline is the first step in determining if scheduled medications are safe to administer.
2
Evaluate the laboratory results against the prescribed medications.
The platelet count of 95,000/mm³ indicates thrombocytopenia. Enoxaparin is an anticoagulant and is contraindicated when platelet counts are critically low due to severe bleeding risk.
Medications must be correlated with current diagnostic data to prevent adverse drug events.
3
Synthesize data to determine the safety of the remaining medications.
Furosemide is a loop diuretic that decreases fluid volume. Administering it to a client with a blood pressure of 90/58 mm Hg will worsen the hypotension and decrease perfusion further.
Pharmacological principles dictate holding medications that will exacerbate abnormal physiological parameters.
4
Select the appropriate nursing intervention within the practical nursing scope of practice.
The nurse must withhold all medications and escalate the situation immediately to the registered nurse or primary healthcare provider for urgent medical intervention.
The practical nurse must recognize when a client's condition exceeds the stability required for routine medication administration and requires higher-level clinical judgment.

While performing a postoperative assessment, a licensed practical nurse (LPN) evaluates a client who underwent a percutaneous coronary intervention via the right femoral artery 4 hours ago. The client reports a new, continuous dull ache in the lower back. Inspection of the right groin reveals a dry surgical dressing with no localized swelling. Bilateral pedal pulses are palpable and symmetric. The client's baseline vital signs were blood pressure 144/82 mm Hg and heart rate 70 bpm. Current vital signs are blood pressure 104/62 mm Hg, heart rate 116 bpm, and respirations 20/min. Based on these findings, which action should the LPN take first?

Cevabı ve açıklamayı göster

Cevap: Immediately notify the registered nurse of the vital sign trends and the client's back pain.

Cevap

The LPN should immediately notify the registered nurse of the vital sign trends and the client's back pain.
The correct action is to immediately notify the registered nurse. After a femoral artery procedure, blood can leak internally into the retroperitoneal space. Because the bleeding is internal, the external groin dressing often remains dry and intact. The classic presentation of a retroperitoneal hemorrhage includes new-onset lower back or flank pain, accompanied by hemodynamic instability (tachycardia and hypotension). The LPN must recognize these subtle shock signs and escalate care immediately to prevent severe hypovolemia.

Adım Adım Çözüm

1
Analyze the client's procedure and current symptoms.
The client had a right femoral artery puncture and is now experiencing new-onset lower back pain.
Back or flank pain after a femoral catheterization is a primary indicator of retroperitoneal bleeding, where blood pools in the retroperitoneal cavity rather than at the visible groin site.
2
Evaluate the vital sign trends against the baseline.
Blood pressure has dropped significantly (144/82 to 104/62) and heart rate has increased (70 to 116).
Tachycardia and hypotension are compensatory mechanisms indicating early hypovolemic shock due to internal blood loss.
3
Determine the priority nursing intervention within the LPN scope of practice.
The LPN must escalate these findings to the RN immediately.
A retroperitoneal hemorrhage is a life-threatening complication that requires rapid fluid resuscitation, potential blood transfusions, and possible surgical intervention, all of which require RN and provider collaboration.

A practical nurse (PN) is caring for a postpartum client. During the admission assessment, the client explicitly requests that no information regarding her hospitalization or the newborn be shared with anyone. Later in the shift, an individual calls the nursing station, identifies themselves as the client's parent, provides the client's full name and room number, and asks for a brief medical update. Which of the following is the most appropriate response by the PN?

Cevabı ve açıklamayı göster

Cevap: I have no information available regarding an individual by that name.

Cevap

The most appropriate response is to state that there is no information available regarding an individual by that name.
When a client requests that no information be shared regarding their admission, they are essentially opting out of the facility directory. Under these privacy regulations, nurses must maintain strict confidentiality and cannot acknowledge or confirm the individual's presence at the facility to anyone, including family members. The most appropriate response is to state that no information is available.

Adım Adım Çözüm

1
Analyze the client's specific privacy request.
The client opted for complete privacy, meaning her presence in the facility cannot be confirmed to outside callers.
Healthcare privacy laws mandate that providers respect a competent client's right to control who knows about their hospitalization.
2
Evaluate the caller's request and provided information.
Despite the caller having accurate identifying information (name and room number), the PN cannot confirm the client is there.
Possessing a room number or knowing a client's full name does not override the client's explicit request for non-disclosure.
3
Select the response that best protects the client's privacy.
The PN must use standard phrasing to deny the request without confirming the client's admission status.
Stating that no information is available protects confidentiality without providing false information to the caller.

The correct sequence is to first clamp the tubing to collect fresh urine, then scrub the port with an antiseptic, aspirate the urine with a sterile syringe, transfer it to a sterile container, and finally unclamp the tubing to prevent bladder distension.
To safely collect a sterile urine specimen from an indwelling catheter, the LPN must first clamp the tubing to allow fresh urine to collect. Once collected, the port must be disinfected to prevent infection. The urine is then aspirated with a sterile syringe and safely transferred to a sterile cup. Finally, unclamping the tubing is critical to prevent bladder distension and associated complications.

Adım Adım Çözüm

1
Clamp the drainage tubing just below the collection port for 15 to 30 minutes.
Fresh urine accumulates in the tubing above the clamp.
Urine collected from the drainage bag is not sterile and cannot be used for a culture. Clamping ensures a fresh sample is available at the port.
2
Scrub the catheter aspiration port with an approved antiseptic wipe.
The port surface is disinfected.
Cleaning the port eliminates surface pathogens, reducing the risk of introducing bacteria into the closed urinary system (CAUTI).
3
Attach a sterile syringe to the aspiration port and withdraw the required volume of urine.
A sterile specimen is safely extracted from the tubing.
Using a sterile syringe maintains the sterility of both the specimen and the closed drainage system.
4
Transfer the aspirated urine into a sterile specimen container without contaminating the rim.
The specimen is secured in the transport container.
Preventing contact between the syringe and the rim of the cup ensures the culture will only grow organisms present in the client's urine.
5
Unclamp the drainage tubing to restore the free flow of urine.
Continuous urinary drainage resumes.
Failing to unclamp the tubing is a significant risk factor that can lead to urinary retention, severe bladder distension, and retrograde flow to the kidneys.

Understanding the medication's expected side effects guides the nurse on which specific laboratory values to monitor most closely.
2
Evaluate each laboratory option against expected normal adult reference ranges.
The potassium level of 2.8 mEq/L is well below the normal range (3.5-5.0 mEq/L). The BUN, sodium, and magnesium levels are all within their respective normal limits.
The practical nurse must be able to rapidly differentiate between normal expected findings and abnormal critical values to ensure client safety.
3
Determine the required nursing action for the abnormal finding.
The abnormally low potassium level (hypokalemia) must be reported to the registered nurse immediately.
Severe hypokalemia can trigger lethal cardiac dysrhythmias, making it the highest priority finding that requires urgent medical intervention.

Cevap: Administering scheduled oral antihypertensive medications to a clinically stable client who is two days post-myocardial infarction.

Cevap

Administering scheduled oral antihypertensive medications to a clinically stable client who is two days post-myocardial infarction.
The correct answer involves providing routine care to a clinically stable client. Administering scheduled oral medications to a client who is two days post-myocardial infarction and stable is entirely within the recognized legal scope of practice for a practical nurse.

Adım Adım Çözüm

1
Analyze each proposed action to determine if it falls within the legal and safe scope of practice for a practical nurse.
Three actions are identified as unsafe or outside the PN scope, while one is a standard PN task.
Safe delegation and assignment require adherence to legal practice boundaries and prompt recognition of critical client changes.
2
Evaluate the educational and consent-related tasks.
Formulating an initial teaching plan is an RN responsibility, and explaining procedural risks is a provider responsibility.
The PN scope allows for reinforcement of teaching and witnessing consent signatures, but not initial complex education or obtaining informed consent.
3
Evaluate the clinical data task.
A potassium level of 2.8 mEq/L2.8 \text{ mEq/L} is identified as a critical laboratory value.
Normal potassium is 3.53.5 to 5.0 mEq/L5.0 \text{ mEq/L}. Hypokalemia can cause severe arrhythmias, necessitating immediate escalation rather than delaying for shift handoff.
4
Verify the remaining action.
Administering routine oral medications to a stable client is confirmed as the correct action.
This task does not require complex initial assessment or intervention, making it perfectly suited for the PN scope of practice.

Prior to an elective hernia repair, a client who has already signed the surgical consent form suddenly states to the practical nurse (PN), "I have changed my mind. I do not want to go through with this operation today." Which action should the PN take first?

Cevap: Notify the operating surgeon and the charge nurse immediately regarding the client's decision.

Cevap

Notify the operating surgeon and the charge nurse immediately regarding the client's decision.
Clients retain the legal and ethical right to withdraw informed consent at any time prior to the initiation of a procedure, regardless of having previously signed a consent form. When a client revokes consent, the immediate priority for the practical nurse is to communicate this critical information to the healthcare provider and the charge nurse so that surgical preparations are halted and the provider can appropriately discuss the decision with the client.

Adım Adım Çözüm

1
Recognize that a client has the absolute right to revoke informed consent at any point before a procedure begins.
The PN identifies that the client's statement constitutes a legal withdrawal of consent.
Informed consent is an ongoing, voluntary process, not simply the act of signing a physical document.
2
Determine the boundaries of the PN scope of practice in this specific scenario.
The PN acknowledges that discussing the medical risks of refusal or altering procedure orders is the provider's responsibility.
The PN's legal role is to advocate for the client and communicate critical changes in status to the healthcare team.
3
Prioritize the immediate next step to ensure client safety and honor their legal rights.
The PN selects the action to immediately escalate the client's decision to the operating surgeon and charge nurse.
The surgical team must be alerted immediately to halt preoperative preparations and allow the provider to speak directly with the client.

Anahtar Kavram

A client has the right to revoke informed consent at any time, and the practical nurse's priority is to immediately notify the healthcare provider of this change without attempting to educate on medical risks.

Öğeler

A representative from the local health department requests medical records for a client newly diagnosed with active pulmonary tuberculosis.
A neighbor visiting the hospital stops the PN in the hallway to ask how the client is recovering from a recent stroke.
The physical therapist assigned to the client asks to review the electronic health record to check the timing of the client's last pain medication dose.
An unlicensed assistive personnel (UAP) assigned to transport the client to radiology asks if the client has a specific bloodborne infectious disease.

Cevap

Health department request maps to permissible for public health; neighbor inquiry maps to impermissible without consent; physical therapist request maps to permissible for care coordination; UAP inquiry maps to impermissible because standard precautions apply universally.
Each scenario is evaluated against HIPAA guidelines and the practical nursing scope of practice. Disclosures to direct care team members and public health authorities are legally permissible. Conversely, disclosures to unauthorized visitors or staff without a direct need-to-know violate client confidentiality.

Adım Adım Çözüm

1
Analyze the request from the health department for the client with tuberculosis.
Matches with permissible disclosure required for public health reporting.
Tuberculosis is a reportable disease, and public health laws mandate disclosure to appropriate agencies, overriding general HIPAA restrictions.
2
Evaluate the neighbor's request for information about the client's stroke recovery.
Matches with impermissible disclosure requiring explicit client consent.
Nurses cannot disclose any health information to visitors, friends, or neighbors without explicit permission from the client or their designated proxy.
3
Assess the physical therapist's need to check the pain medication schedule.
Matches with permissible disclosure under the need-to-know basis for care coordination.
Healthcare team members directly involved in the client's care are permitted access to the medical record to coordinate and safely provide treatment.
4
Determine the validity of the UAP's request regarding the client's bloodborne disease status for transport.
Matches with impermissible disclosure because standard precautions apply regardless of the diagnosis.
The transporter does not require the specific diagnosis to perform their duty. Standard precautions are required for all clients to prevent transmission of bloodborne pathogens.

Anahtar Kavram

Under HIPAA, client information may only be disclosed on a 'need-to-know' basis for treatment, payment, or healthcare operations, or when legally mandated (e.g., public health reporting).
