Cevabı ve açıklamayı göster

Cevap

The correct sequence prioritizes source control first by masking the client, followed by protecting the immediate bystander (roommate), protecting the nurse (donning the N95), ensuring definitive environmental isolation (AIIR transfer), and finally documenting the event.
Infection control prioritization dictates that when a healthcare worker is already at the bedside and discovers an airborne risk, source control (masking the client) is the fastest and most effective first step. This is followed by removing bystanders, protecting oneself with appropriate PPE, establishing long-term environmental controls (AIIR), and concluding with documentation.

Adım Adım Çözüm

1
Place a standard surgical mask over the client's nose and mouth.
The client's infectious respiratory secretions are contained.
Immediate source control is the highest priority to stop the spread of droplet nuclei into the shared environment.
2
Instruct the client's roommate to leave the room and wait in a safe area.
The secondary contact is removed from the contaminated environment.
Protecting the most immediately vulnerable bystander from further exposure is the next crucial step in infection control.
3
Exit the room temporarily to perform hand hygiene and don a fit-tested N95 respirator.
The nurse is properly protected against airborne pathogens.
Proper personal protective equipment must be obtained and donned before any further prolonged direct contact or assessment occurs.
4
Coordinate with the nursing supervisor to transfer the client to an airborne infection isolation room (AIIR).
Definitive environmental isolation is arranged.
Airborne precautions require negative-pressure ventilation, which cannot be achieved in a standard semi-private room.
5
Document the client's respiratory findings and the initiation of isolation measures in the health record.
An accurate medical and legal record is created.
Documentation must reflect the findings and interventions but is always performed after physical safety is secured.

A home health licensed practical nurse (LPN) is visiting a client who is recovering from a recent stroke. The client's spouse of 40 years died unexpectedly two weeks ago. When the nurse arrives, the client yells, "Get out! I do not need your help or anyone else's!" Which response by the nurse is the most appropriate?

Cevabı ve açıklamayı göster

Cevap: You have experienced a tremendous loss. I will just sit here quietly with you.

Cevap

The most appropriate response is to acknowledge the magnitude of the client's loss and offer a supportive, silent presence.
The correct response utilizes the therapeutic communication techniques of acknowledging the client's feelings and 'offering self.' Anger and displacement are normal manifestations of acute grief. By validating the magnitude of the loss and offering a quiet, non-judgmental presence, the nurse provides a safe environment for the client to process their emotions without feeling pressured, abandoned, or confronted.

Adım Adım Çözüm

1
Analyze the underlying cause of the client's behavior.
The client's hostility is identified as a normal manifestation of acute grief related to the sudden death of their spouse, rather than true refusal of care or a personal attack.
Anger is a common emotion during the grieving process and is frequently displaced onto healthcare providers or surviving family members.
2
Select the nursing response that utilizes therapeutic communication techniques.
The nurse chooses to acknowledge the client's loss and offer a quiet, non-judgmental presence.
Therapeutic communication prioritizes the client's emotional safety. 'Offering self' provides support and validates the client's current emotional state without escalating the conflict.

Cevap: Blood pressure decreases from an admission baseline of 138/82 mm Hg to 104/66 mm Hg.; The client becomes suddenly disoriented to time and place during the assessment.; The resting apical heart rate is 114 beats per minute with a thready quality.

Cevap

The correct findings are the decrease in blood pressure, the sudden disorientation, and the tachycardic, thready pulse.
The correct findings represent hallmark early signs of hypovolemic shock due to severe fluid volume deficit. A significant downward trend in blood pressure, compensatory tachycardia with a weak pulse, and sudden altered mental status (indicating decreased cerebral perfusion) are acute, life-threatening changes that require immediate rapid intervention.

Adım Adım Çözüm

1
Analyze the client's admitting diagnosis (severe diarrhea and vomiting) to identify the primary physiological risk.
The client is at extremely high risk for fluid volume deficit progressing to hypovolemic shock.
Prolonged gastrointestinal fluid loss significantly decreases circulating blood volume.
2
Evaluate each assessment finding to differentiate between expected baseline symptoms and acute, life-threatening complications.
Abdominal cramping and diarrhea are expected. Normal capillary refill is reassuring. The dropping blood pressure, tachycardia, and confusion are unexpected acute changes.
Safe prioritization requires identifying new, unstable, or systemic changes over localized, expected symptoms.
3
Identify the specific findings that indicate compromised Airway, Breathing, or Circulation (ABCs).
The dropping blood pressure, compensatory tachycardia (114 beats/min), and sudden disorientation indicate poor systemic and cerebral perfusion.
These are early hallmark signs of impending hypovolemic shock requiring immediate escalation to the registered nurse.

An unresponsive client requires morning oral hygiene. How should the nurse sequence the following interventions? (Arrange the steps from first to last.)

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first turn the client onto their side, then arrange the towel and basin, proceed to swab the oral cavity, and finally apply moisturizer to the lips.
The absolute priority when providing oral care to an unresponsive client is airway management. Positioning the client on their side must always occur first to allow fluids to drain out of the mouth, thereby preventing aspiration. After the airway is secure, preparation of the physical environment with a towel and basin ensures cleanliness. The actual mechanical cleaning of the oral cavity follows. Finally, applying a water-soluble moisturizer provides comfort and preserves skin integrity.

Adım Adım Çözüm

1
Protect the airway
The client is placed in a side-lying position.
An unresponsive client lacks an intact gag reflex. Turning them on their side ensures fluids drain out of the mouth rather than pooling in the back of the throat, which prevents aspiration.
2
Prepare the immediate area
A towel and emesis basin are placed near the client's face.
This setup catches oral secretions and cleaning solutions, keeping the client's skin and bed linens dry and clean.
3
Perform oral hygiene
The teeth, gums, and tongue are gently cleansed.
Using a moistened sponge removes plaque, bacteria, and crusts to maintain oral health.
4
Provide skin protection
Water-soluble moisturizer is applied to the lips.
Moisturizer prevents the lips from drying, cracking, and bleeding, completing the comfort care procedure.

Cevabı ve açıklamayı göster

Cevap: Direct other clients and visitors to leave the immediate area.; Maintain a personal distance of at least two arm lengths from the client.; Communicate using a calm, low-pitched voice and concise sentences.

Cevap

The correct actions are to direct other clients and visitors to leave the immediate area, maintain a personal distance of at least two arm lengths, and communicate using a calm, low-pitched voice and concise sentences.
When a client exhibits signs of escalating behavior, the immediate priority is milieu safety and de-escalation. Directing other clients and visitors away removes them from potential harm and decreases the audience, which can help calm the escalated client. Maintaining at least two arm lengths of distance protects the nurse from sudden physical strikes. Finally, communicating with a calm, low-pitched voice and using concise sentences provides clear, non-threatening direction without increasing the client's sensory overload.

Adım Adım Çözüm

1
Identify the clinical situation from the data collected.
The client is demonstrating signs of acute behavioral escalation and potential aggression, evidenced by rapid pacing, loud speech, and clenched fists.
Recognizing early signs of a behavioral crisis dictates the priority of nursing interventions.
2
Determine the priority nursing goals.
The primary goals are to ensure the safety of the milieu (client, staff, and bystanders) and to attempt non-pharmacological verbal de-escalation.
Safety is always the immediate priority in any psychiatric or behavioral emergency.
3
Evaluate each intervention against safety standards and the PN scope of practice.
Removing bystanders, maintaining distance, and using calm communication promote safety and de-escalation. Asking 'why', using immediate restraints, and administering IV push medications violate therapeutic communication, least restrictive alternative mandates, and the PN scope of practice, respectively.
Nursing interventions must be safe, therapeutic, legally sound, and follow a stepwise approach from least to most restrictive.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for a midstream clean-catch urine collection is: cleanse the perineal area, begin voiding into the toilet, place the container in the active stream, remove the container before stopping urination, and securely apply the lid.
The correct chronological sequence ensures the urine sample is as sterile as possible. Cleansing the area removes surface bacteria. Voiding a small amount flushes the urethra. Collecting the midstream sample captures urine directly from the bladder. Removing the cup before stopping prevents terminal contamination, and securing the lid safely finalizes the aseptic technique.

Adım Adım Çözüm

1
Identify the first necessary action to prevent specimen contamination.
Cleanse the perineal area from front to back with the provided antiseptic wipes.
Removing external bacteria from the meatus is the essential first step before any urination begins.
2
Determine the next action to further clear potential contaminants.
Begin voiding a small amount of urine directly into the toilet.
The initial stream flushes resident bacteria out of the distal urethra.
3
Identify when to actually collect the urine sample.
Place the sterile specimen container into the active stream to collect the sample.
The midstream portion of the urine represents the most uncontaminated sample from the bladder.
4
Determine the action needed to conclude the collection safely.
Remove the specimen container from the urine stream before stopping urination.
Pulling the cup away while the stream is still strong prevents contamination from the skin as the flow dwindles.
5
Identify the final step to secure the specimen.
Securely apply the lid to the container without touching its inner surface.
Properly sealing the container maintains its internal sterility until it reaches the laboratory.

During morning rounds, a client receiving daily oral levothyroxine 150 mcg150\text{ mcg} for primary hypothyroidism reports feeling restless and unusually warm. The practical nurse notes a heart rate of 112 bpm112\text{ bpm} and a blood pressure of 142/88 mmHg142/88\text{ mmHg}. A review of the morning laboratory results reveals a thyroid-stimulating hormone (TSH) level of 0.1 mU/L0.1\text{ mU/L} (normal: 0.4 to 4.0 mU/L0.4\text{ to }4.0\text{ mU/L}). Which action should the practical nurse take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled dose of levothyroxine and report the assessment findings to the registered nurse.

Cevap

The practical nurse should withhold the scheduled dose of levothyroxine and notify the registered nurse.
The client is exhibiting clinical signs of hyperthyroidism (tachycardia, heat intolerance, restlessness, elevated blood pressure) alongside a suppressed TSH level. These findings indicate levothyroxine toxicity. The safest and most appropriate action within the practical nurse's scope of practice is to withhold the scheduled dose to prevent further physiological harm and immediately escalate the critical findings to the registered nurse or healthcare provider for medical re-evaluation.

Adım Adım Çözüm

1
Analyze the client's physical symptoms and vital signs.
Restlessness, feeling warm, and tachycardia (112 bpm112\text{ bpm}) are identified as classic signs of a hypermetabolic state.
Identifying abnormal assessment findings is the critical first step in evaluating medication safety prior to administration.
2
Interpret the laboratory results in the context of the medication.
A TSH level of 0.1 mU/L0.1\text{ mU/L} is significantly below the normal range, indicating excessive circulating thyroid hormone.
TSH has an inverse relationship with thyroid hormone levels; a suppressed TSH confirms hyperthyroidism or levothyroxine toxicity.
3
Determine the appropriate nursing action within the practical nurse scope of practice.
The medication must be withheld and the clinical findings immediately escalated to the registered nurse or provider.
Administering the medication would exacerbate the toxicity, and altering the prescribed dose independently is strictly outside the practical nurse's scope.

The correct sequence is to first clean the site with alcohol, allow it to dry completely, puncture the side of the finger, wipe away the initial drop of blood, and then apply the second drop to the test strip.
To obtain an accurate capillary blood glucose reading and reduce the risk of potential complications, the practical nurse must follow a strict procedural sequence. First, the site is cleaned to prevent infection. Second, the alcohol must dry completely to prevent it from altering the glucose reading. Third, the puncture is made on the less sensitive side of the finger. Fourth, the first drop of blood is wiped away because it contains tissue fluid that dilutes the sample. Finally, the second drop of pure capillary blood is applied to the test strip for an accurate measurement.

Adım Adım Çözüm

1
Clean the selected puncture site with an alcohol swab.
The skin surface is sanitized.
Reduces the risk of infection by removing surface pathogens before breaking the skin.
2
Allow the alcohol on the skin to dry completely.
The alcohol evaporates from the puncture site.

Cevap: Assist the client into a prone position with the hips completely flat for 20 to 30 minutes several times daily.; Wrap the residual limb with an elastic compression bandage using a figure-eight technique, proceeding from distal to proximal.; Encourage the client to actively push the residual limb downward against the bed mattress while resting in a supine position.

Cevap

The correct interventions are assisting the client into a prone position, wrapping the residual limb with a figure-eight technique, and encouraging the client to actively push the limb against the mattress.
Appropriate basic care for a client with a recent lower extremity amputation involves interventions that prepare the limb for a prosthesis and prevent complications. Assisting the client to a prone position for 20 to 30 minutes multiple times a day stretches the flexor muscles and prevents hip flexion contractures. Wrapping the residual limb with a figure-eight technique from distal to proximal reduces edema and properly shapes the limb for a future prosthesis, while avoiding the restricted blood flow associated with circular wrapping. Encouraging the client to push the limb down against the mattress strengthens the necessary muscles and further prevents contracture formation.

Adım Adım Çözüm

1
Evaluate the positioning, mobility, and healing needs for a client recovering from a lower extremity amputation.
Identified that preventing hip flexion contractures and correctly shaping the residual limb are primary priorities for basic care and comfort during the rehabilitative phase.
Contractures can permanently prevent the successful fitting and use of a prosthetic limb, undermining the entire rehabilitation process.
2
Analyze each proposed intervention against evidence-based basic care standards and the practical nursing scope of practice.
Selected prone positioning, figure-eight wrapping, and active muscle pushing as correct actions. Rejected continuous pillow elevation, intravenous push administration, and bypassing cultural dietary assessments as unsafe or inappropriate.
Safe nursing practice requires strict adherence to physiological principles (avoiding contractures), legal boundaries (refusing out-of-scope tasks), and psychosocial integrity (respecting cultural diets).

Cevabı ve açıklamayı göster

Cevap

The correct sequence prioritizes airway safety by first positioning the client laterally, followed by preparing the equipment, safely accessing the oral cavity, performing the cleaning, and finally removing the fluids with suction.
The sequencing of oral care for an unconscious client is strictly dictated by airway safety. Positioning the client laterally is always the first priority to prevent aspiration. Only after the airway is protected from gravity-induced pooling should the nurse prepare the linens, open the mouth safely with an instrument, perform the hygiene, and finally suction out the debris.

Adım Adım Çözüm

1
Establish a safe position for the unconscious client.
The client is placed in a lateral (side-lying) position with the head turned to the side.
Because the client cannot swallow or expectorate, this position allows fluids to drain out of the mouth, preventing pulmonary aspiration.
2
Prepare the immediate area.
A towel and emesis basin are placed under the client's chin and cheek.
This protects the bed linens and provides a direct path for fluids to drain into the basin.
3
Open the oral cavity safely.
A padded tongue blade is inserted between the upper and lower back teeth.
This ensures safe access to the oral cavity without risking injury to the nurse's fingers if the client experiences an involuntary bite reflex.
4
Perform oral hygiene.
The oral cavity is thoroughly cleaned with a moistened sponge swab or soft-bristled toothbrush.
Cleaning removes plaque, bacteria, and crusts, preventing infection and maintaining the integrity of the mucous membranes.
5
Remove excess fluids.
The mouth is suctioned using a Yankauer or standard suction catheter.
Suctioning eliminates pooling fluids and loosened secretions, completing the cleaning process while continuing to protect the airway.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: draw the medication and replace the needle, displace the skin laterally, insert the needle at 90 degrees, inject slowly, wait 10 seconds, and finally withdraw the needle while releasing the skin.
The Z-track method is meticulously designed to seal highly irritating or staining medications (such as iron dextran) deep within the muscle tissue. The process begins with drawing up the medication and strictly changing the needle to ensure no residue is on the needle shaft. Next, the skin is pulled laterally to displace the tissue layers. The needle is then inserted at a 90-degree angle, and the medication is injected slowly. The nurse must wait 10 seconds before withdrawing the needle to allow the fluid to disperse and prevent backflow. Finally, withdrawing the needle and immediately releasing the skin creates a staggered track, effectively trapping the medication in the muscle layer and preventing superficial damage.

Adım Adım Çözüm

1
Draw up the medication and change the needle.
A sterile needle without irritating medication residue on the outside is attached to the syringe.
Prevents tracking of the highly irritating or staining medication through superficial tissues during insertion.
2
Displace the skin and subcutaneous tissue laterally.
The superficial tissue layers are misaligned with the deeper muscle layers.
Creates the mechanical foundation required for the Z-track seal.
3
Insert the needle at 90 degrees and inject slowly.
Medication is deposited deep into the ventrogluteal muscle.
Ensures proper depth, prevents subcutaneous pooling, and minimizes tissue trauma.
4
Wait 10 seconds before needle withdrawal.
The medication begins to disperse into the surrounding muscle.
Prevents immediate backflow of the fluid into the needle track.
5
Withdraw the needle and simultaneously release the skin.
The tissue layers slide back into their natural alignment.
The staggered needle track is closed, physically sealing the medication deep within the muscle layer.

Cevap: Hemoglobin level of 7.8 g/dL7.8 \text{ g/dL} (78 g/L78 \text{ g/L}) and hematocrit of 24%24\%; Heart rate of 112 beats/minute112 \text{ beats/minute} with a blood pressure of 96/60 mm Hg96/60 \text{ mm Hg}; New-onset petechiae scattered across the anterior chest and axillae

Cevap

The findings that require immediate escalation are the critically low hemoglobin/hematocrit, the tachycardia with borderline hypotension, and the petechial rash on the chest.
Clients with long bone fractures are at high risk for hemorrhage and fat embolism syndrome. A critical drop in hemoglobin, tachycardia combined with borderline hypotension, and a new-onset petechial rash on the chest are hallmark signs of these life-threatening complications. These physiological changes indicate a deteriorating state that falls outside the practical nurse's independent scope and mandates immediate escalation to the registered nurse.

Adım Adım Çözüm

1
Evaluate the surgical context and inherent risks
The client had an ORIF of the femur
Long bone fractures and orthopedic surgeries carry high physiological risks for severe hemorrhage and fat embolism syndrome (FES).
2
Analyze laboratory and vital signs for indications of shock
Identified that a hemoglobin of 7.8 g/dL7.8 \text{ g/dL} and vitals of 112 bpm112 \text{ bpm} with 96/60 mm Hg96/60 \text{ mm Hg} are abnormal
These specific values represent acute blood loss and early hypovolemic shock, requiring immediate RN intervention.
3
Assess physical findings for FES
Identified petechiae on the anterior chest and axillae
This is a classic, life-threatening clinical indicator of FES that occurs when fat droplets enter the circulation, requiring emergency escalation.
4
Differentiate expected postoperative findings from emergencies
Excluded the WBC of 9,500/mm39,500/\text{mm}^3, the 25 mL25 \text{ mL} of drainage, and the pain level of 6/106/10
These findings are within normal postoperative limits or fall within the independent scope of the practical nurse to manage, preventing unnecessary escalation.

An adult client in an inpatient psychiatric unit receives scheduled clozapine for treatment-resistant schizophrenia. During the morning medication pass, the practical nurse observes that the client has a new-onset temperature of 101.4∘F101.4^\circ\text{F} (38.6∘C38.6^\circ\text{C}), severe pharyngitis, and marked lethargy. The morning laboratory report indicates a white blood cell (WBC) count of 1,800/mm31,800/\text{mm}^3 (1.8×109/L1.8 \times 10^9/\text{L}). Based on these findings, which action should the practical nurse take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled dose of the medication and immediately report the clinical findings and laboratory results to the registered nurse.

Cevap

The correct action is to withhold the scheduled dose of the medication and immediately escalate the clinical findings to the supervising registered nurse.
Clozapine is an atypical antipsychotic associated with a significant risk of agranulocytosis, a potentially fatal drop in white blood cells. A WBC count of 1,800/mm31,800/\text{mm}^3 (1.8×109/L1.8 \times 10^9/\text{L}), combined with signs of infection such as fever and pharyngitis, strongly indicates this adverse effect. The safest and most appropriate action within the practical nurse scope of practice is to withhold the offending agent and immediately escalate the critical findings to the registered nurse for urgent medical intervention.

Adım Adım Çözüm

1
Analyze the client's presenting symptoms and laboratory results.
The client has a fever, pharyngitis, and a critically low WBC count of 1,800/mm31,800/\text{mm}^3 (normal is typically 4,5004,500 to 11,000/mm311,000/\text{mm}^3).
Identifying abnormal clinical and laboratory findings is the foundational step in safe medication administration.
2
Correlate the assessment findings with the prescribed pharmacological therapy.
Clozapine carries a severe risk for agranulocytosis, a dangerous depletion of white blood cells that compromises the immune system.
Connecting the drug to its potential life-threatening adverse effect determines the required clinical intervention.
3
Determine the priority action within the practical nurse's scope of practice.
The nurse must withhold the drug to prevent further harm and immediately report the findings to the registered nurse.
Administering the medication would worsen the life-threatening condition, and independent medical or complex assessment decisions fall outside the practical nursing scope.

Cevap: Withholding a scheduled dose of oral furosemide for a client whose morning serum potassium level is 2.8 mEq/L and alerting the registered nurse.; Declining a delegated task to administer an intravenous push (IVP) dose of morphine to a client experiencing severe postoperative pain.

Cevap

The correct actions are withholding the furosemide due to critical hypokalemia and declining to administer the intravenous push (IVP) morphine.
The correct actions demonstrate a clear understanding of risk reduction. Hypokalemia increases the risk of severe dysrhythmias, so withholding a loop diuretic and notifying the registered nurse is essential. Furthermore, refusing to perform tasks outside the practical nurse scope of practice, such as administering IV push medications, protects the client from potential harm and medication errors.

Adım Adım Çözüm

1
Evaluate each action for adherence to safety protocols, critical value escalation, and practical nursing scope of practice.
Identified that handling medications appropriately and recognizing scope limitations are key components of risk reduction.
Risk reduction requires proactive identification of potential harm.
2
Analyze the action regarding furosemide administration.
A potassium level of 2.8 mEq/L is critically low. Withholding a potassium-depleting diuretic prevents further life-threatening hypokalemia.
Nurses must verify that current laboratory values support the safe administration of scheduled medications.
3
Analyze the action regarding the intravenous push (IVP) medication.
Declining the IVP administration is appropriate because it falls outside the legal and educational scope of the practical nurse.
Practicing within legal boundaries prevents client injury and professional liability.
4
Identify why the remaining actions fail to reduce risk.
The other actions involve ignoring early signs of shock, skipping vital medication identity checks, delaying the report of critical lab values, and accepting assignments beyond the PN scope.
Each of these distractors represents a direct violation of clinical safety and risk potential reduction.

Anahtar Kavram

Risk reduction requires the practical nurse to operate strictly within their defined scope of practice, properly verify client identity, and promptly escalate abnormal physiological findings and critical laboratory values.
