Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Position the client prone for 20 to 30 minutes, three to four times a day.; Keep the left knee fully extended using an amputation board when the client sits in a chair.; Cleanse the residual limb gently with warm water and mild soap, ensuring complete drying.

Cevap

The correct interventions are positioning the client prone periodically, keeping the knee fully extended while sitting, and properly cleansing the residual limb with mild soap and water.
Appropriate basic care for a below-the-knee amputation after the first 24 hours focuses on contracture prevention and skin integrity. Assisting the client into a prone position multiple times a day helps stretch the hip flexors. Supporting the knee in full extension while sitting prevents knee flexion contractures. Washing the residual limb daily with mild soap and water maintains skin integrity and prevents infection without causing chemical irritation.

Adım Adım Çözüm

1
Analyze the client's postoperative timeline and surgical site.
The client is 48 hours postoperative following a left below-the-knee amputation.
The postoperative timeline dictates whether certain positioning strategies (like elevation) are therapeutic or contraindicated.
2
Evaluate the risk of complications associated with this specific amputation.
The primary physical risks are hip and knee flexion contractures, skin breakdown, and infection. The primary psychological risk involves grief over limb loss.
Basic care and comfort must proactively address these specific risks to promote successful rehabilitation.
3
Determine the correct positioning and hygiene interventions.
Prone positioning and knee extension prevent contractures, while daily washing with mild soap prevents skin breakdown. Pillows for elevation and false reassurance must be avoided.
These actions perfectly align with the evidence-based physical and emotional needs of the healing stump.

Anahtar Kavram

Postoperative amputation positioning and basic stump care focus on preventing hip and knee flexion contractures while maintaining skin integrity.

A practical nurse (PN) is reviewing the morning laboratory results and medication administration record for a client being treated for a deep vein thrombosis (DVT). The client has been receiving a continuous intravenous heparin infusion and was recently started on oral warfarin. The morning laboratory results reveal an International Normalized Ratio (INR) of 4.24.2 and a platelet count of 145,000/mm3145,000/\text{mm}^3. The provider has prescribed a scheduled dose of oral warfarin 55 mg and a new, one-time prescription for oral phytonadione 2.52.5 mg. The pharmacy has dispensed the phytonadione as a 55 mg/mL oral liquid.

Based on these findings, what is the priority sequence of actions for the practical nurse to take?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled oral warfarin, notify the registered nurse of the critical INR result, and prepare to administer 0.50.5 mL of the oral phytonadione after checking two distinct client identifiers.

Cevap

The most appropriate sequence is to withhold the scheduled oral warfarin, notify the registered nurse of the critical INR result, and prepare to administer 0.50.5 mL of the oral phytonadione after checking two distinct client identifiers.
An INR of 4.24.2 is supratherapeutic (the normal therapeutic range for DVT is typically 2.02.0 to 3.03.0), placing the client at a high risk for hemorrhage. The PN must prioritize client safety by withholding the scheduled warfarin (an oral anticoagulant) and promptly notifying the RN or provider of the critical laboratory result. Phytonadione (vitamin K) is the standard antidote utilized for warfarin toxicity. The prescribed dose is 2.52.5 mg, and the available concentration is 55 mg/mL. The correct volume to administer is calculated as: (2.52.5 mg / 55 mg/mL) * 11 mL = 0.50.5 mL. Finally, the PN must rigidly adhere to medication safety protocols by verifying two distinct client identifiers prior to administration, even in urgent clinical scenarios.

Adım Adım Çözüm

1
Evaluate the laboratory results against standard therapeutic ranges for the client's condition.
The INR of 4.24.2 is identified as supratherapeutic (above the target of 2.02.0 to 3.03.0 for DVT), indicating a high risk of hemorrhage.
Recognizing critical laboratory values is a fundamental nursing responsibility prior to administering any anticoagulant therapy.
2
Determine the appropriate intervention regarding the scheduled medications.
The scheduled dose of warfarin must be withheld immediately.
Administering additional warfarin to a client with a supratherapeutic INR would dangerously prolong clotting time and precipitate bleeding.
3
Calculate the correct dosage of the prescribed antidote (phytonadione).
The required volume to administer is calculated to be 0.50.5 mL.
Using the standard formula (Desired / Have) * Volume: (2.52.5 mg / 55 mg) * 11 mL = 0.50.5 mL of the phytonadione oral liquid.
4
Identify the proper procedure for safe medication administration and interprofessional communication.
The PN must notify the RN of the critical lab value and verify two distinct client identifiers before administration.
Delegation guidelines require escalating critical findings to the RN, and safety standards universally mandate dual identifier verification, regardless of clinical urgency.

A client diagnosed with schizophrenia is scheduled to receive a morning dose of oral clozapine. Upon reviewing the electronic health record, the practical nurse notes that the client's most recent absolute neutrophil count (ANC) is 800/mm3800/\text{mm}^3. Which action should the nurse take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the dose of clozapine and immediately notify the registered nurse.

Cevap

Withhold the dose of clozapine and immediately notify the registered nurse.
Clozapine carries a black box warning for severe neutropenia and agranulocytosis. An absolute neutrophil count (ANC) of 800/mm3800/\text{mm}^3 is dangerously low. The practical nurse is legally and ethically responsible for reviewing relevant laboratory data prior to administration, withholding the medication if a critical abnormality is found, and promptly notifying the supervising registered nurse or provider.

Adım Adım Çözüm

1
Identify the medication and its associated physiological risks.
Clozapine is an atypical antipsychotic known to cause agranulocytosis, which severely lowers the white blood cell and neutrophil counts.
Understanding the specific adverse effects of a medication is crucial for determining which client assessments and laboratory values require monitoring before administration.
2
Evaluate the client's current laboratory data against normal reference ranges.
The client's absolute neutrophil count (ANC) is 800/mm3800/\text{mm}^3, which is significantly below the normal range (typically 1,5001,500 to 8,000/mm38,000/\text{mm}^3).
Safe medication administration requires ensuring that the client's physiological status can safely tolerate the drug without life-threatening complications.
3
Determine the appropriate nursing intervention within the practical nurse (PN) scope of practice.
The PN must withhold the scheduled dose and immediately escalate the critical laboratory finding to the registered nurse or healthcare provider.
Administering the medication could lead to fatal infection due to severe immunosuppression, and independently altering orders exceeds the PN's legal scope of practice.

A practical nurse (PN) is monitoring a client who had an uncomplicated vaginal delivery 3 hours ago. The client is resting in bed and states, "I feel suddenly very weak and a bit dizzy when I lift my head." The PN notes that the client has saturated one perineal pad over the last 45 minutes. The client's skin is cool and slightly clammy. Vital signs reveal a heart rate of 112 beats/min and a blood pressure of 98/60 mm Hg. Which of the following is the priority action for the PN?

Cevabı ve açıklamayı göster

Cevap: Palpate the uterine fundus and immediately begin fundal massage if it feels soft or boggy.

Cevap

The priority action is to palpate the uterine fundus and immediately begin fundal massage if it feels soft or boggy.
The client's presentation of saturating a perineal pad in under an hour, combined with tachycardia, hypotension, dizziness, and clammy skin, points directly to postpartum hemorrhage and early hypovolemic shock. The most common cause of early postpartum hemorrhage is uterine atony (failure of the uterus to contract). The priority and most effective initial action for the practical nurse is to assess the uterine fundus. If it is soft or boggy, immediate fundal massage must be initiated to stimulate contraction and compress the bleeding vessels before further assistance is summoned.

Adım Adım Çözüm

1
Analyze the clinical findings.
The client has saturated a pad in 45 minutes, has tachycardia (112 bpm), hypotension (98/60 mm Hg), clammy skin, and dizziness.
Recognizing the combination of excessive bleeding and abnormal vital signs identifies the complication as postpartum hemorrhage leading to hypovolemic shock.
2
Determine the priority nursing intervention.
The most common cause of early postpartum hemorrhage is uterine atony. The first action must address the immediate source of bleeding.
By prioritizing airway, breathing, and circulation (ABC), stopping the bleeding is the immediate necessity.
3
Select the correct PN action.
Palpating the fundus and massaging it if boggy is the appropriate direct intervention within the PN's scope of practice.
Fundal massage stimulates uterine contraction, which compresses bleeding vessels and reduces hemorrhage.

Shake the inhaler vigorously for 3 to 5 seconds.
The medication and propellant are thoroughly mixed.
Ensures the correct dose of medication is delivered when actuated.
2
Exhale deeply to empty the lungs completely.
The lungs are emptied of air.
Prepares the lungs to take in a deep breath and draw the medication as deeply as possible into the lower airways.
3
Place the mouthpiece into the mouth and form a tight seal with the lips.
A secure airway connection is established.
Prevents the medication from escaping from the corners of the mouth during administration.
4
Press down firmly on the canister while inhaling slowly and deeply.
The medication is released and drawn into the respiratory tract.
Simultaneous actuation and inhalation carry the aerosolized particles down into the bronchioles.
5
Hold the breath for at least 10 seconds before exhaling slowly.
The medication settles in the lower airways.
Allows time for the medication to deposit onto the walls of the airways rather than being immediately exhaled.

Cevap: Elevate the client's right arm on a pillow to facilitate lymphatic drainage.; Place the client in a semi-Fowler's position to promote comfortable breathing.; Instruct the client to squeeze a soft washcloth or ball with the right hand.

Cevap

The correct actions include elevating the right arm on a pillow, placing the client in a semi-Fowler's position, and instructing the client to perform hand-squeezing exercises.
Appropriate basic care following a mastectomy focuses on preventing lymphedema and respiratory complications. Elevating the affected arm uses gravity to encourage lymphatic fluid return. A semi-Fowler's position reduces tension on the surgical site and promotes full lung expansion. Early, gentle hand exercises enhance circulation and prevent muscle contractures without straining the surgical area.

Adım Adım Çözüm

1
Analyze the client's surgical procedure and anatomical risks.
The client had a right-sided mastectomy, meaning the right chest wall, axilla, and right arm are at high risk for swelling (lymphedema), impaired circulation, and compromised healing.
Understanding the anatomical risks determines safe positioning and activity limits.
2
Evaluate the positioning and comfort options based on the surgical risks.
Elevating the affected arm and using a semi-Fowler's position are identified as safe and effective to promote drainage and breathing. Early hand exercises promote circulation. Conversely, lying on the operative side is contraindicated because it compresses the area.
Proper body alignment and early gentle movement prevent lymphedema and respiratory complications.

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to first position the client appropriately, lubricate the tube, insert the tube into the rectum, elevate the container to begin the flow, and finally, monitor the client and adjust the flow if cramping occurs.
Administering a large-volume enema requires a systematic approach to ensure safety, effectiveness, and comfort. The nurse must first place the client in the left lateral Sims' position to align with the anatomy of the descending colon. Once positioned, the nurse lubricates the tube to prevent mucosal trauma. The tube is then gently inserted 3 to 4 inches, following the direction of the umbilicus. After safe placement, the nurse elevates the container 12 to 18 inches above the anus and unclamps it to initiate the flow. Throughout the procedure, the nurse monitors the client's tolerance, lowering the container or clamping the tube if cramping occurs to allow the colon to relax.

Adım Adım Çözüm

1
Position the client in the left lateral Sims' position.
The client is anatomically aligned for the procedure.
The left lateral position allows the enema solution to flow downward by gravity into the sigmoid colon.
2
Lubricate the distal end of the rectal tube.
The tube is prepared for safe insertion.
Water-soluble lubricant prevents tissue damage and eases the tube's passage through the anal sphincters.
3
Insert the tube 3 to 4 inches toward the umbilicus.
The tube is securely positioned in the rectum.
This depth and angle follow the natural course of the bowel and prevent perforation.
4
Elevate the container and unclamp the tubing.
The solution begins to instill into the colon.
A height of 12 to 18 inches ensures adequate pressure without causing rapid distention of the bowel.
5
Lower the container if the client experiences cramping.
The instillation rate is reduced or paused.
Stopping the flow temporarily relieves colon spasms and promotes fluid retention.

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.

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.

Adım Adım Çözüm

1
Identify the normal therapeutic range for theophylline.
The therapeutic range is 10−20 mcg/mL10-20\text{ mcg/mL}.
Knowledge of narrow therapeutic index drugs is required to interpret the morning laboratory results.
2
Analyze the client's current laboratory value and clinical symptoms.
The level of 23 mcg/mL23\text{ mcg/mL} is toxic. The restlessness, nausea, and tachycardia are early clinical manifestations of this toxicity.
Connecting the objective data (lab value) with subjective/objective clinical signs (nausea, high heart rate, restlessness) confirms a systemic toxic reaction rather than simple anxiety or disease progression.
3
Identify the pharmacological cause of the toxicity.
Ciprofloxacin inhibits the CYP450 enzymatic pathway, decreasing theophylline clearance and causing serum levels to rise.
Recognizing drug-drug interactions is critical for preventing adverse events when new medications are added to a client's regimen.
4
Determine the safest action within the PN scope of practice.
The PN must safely withhold the offending agent and immediately report the life-threatening risk to the RN.
The PN is responsible for basic data collection, holding unsafe medications, and reporting abnormal/critical findings to the supervising RN for advanced intervention.

While conducting evening rounds on a medical-surgical unit, a practical nurse evaluates a client who is 12 hours post-thyroidectomy. The client states, 'My lips and fingers feel like they are vibrating.' The nurse observes a respiratory rate of 22 breaths/min, a heart rate of 108 beats/min, and a blood pressure of 102/64 mm Hg. The most recent serum calcium level is reported as 7.2 mg/dL (1.80 mmol/L). Which action should the practical nurse take immediately?

Cevap: Report the clinical symptoms, vital signs, and laboratory results to the supervising registered nurse.

Cevap

Report the clinical symptoms, vital signs, and laboratory results to the supervising registered nurse.
The client is exhibiting characteristic signs of acute hypocalcemia (circumoral and extremity paresthesia) following a thyroidectomy. This condition can rapidly progress to life-threatening laryngospasm, seizures, or cardiac arrhythmias. The practical nurse must immediately escalate these critical assessment findings, borderline vital signs, and abnormal laboratory values to the registered nurse for prompt collaborative intervention.

Adım Adım Çözüm

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.

A pediatric client weighing 44 lb44\text{ lb} (20 kg20\text{ kg}) has a new prescription for phenytoin oral suspension at 5 mg/kg/day5\text{ mg/kg/day} divided into two equal doses. The unit's medication supply contains phenytoin at a concentration of 125 mg/5 mL125\text{ mg}/5\text{ mL}. When retrieving and delivering this medication, which action by the practical nurse (PN) represents safe pharmacological practice?

Cevabı ve açıklamayı göster

Cevap: Draw up 2.0 mL2.0\text{ mL} into an oral syringe and confirm the client's identity using their name and date of birth.

Cevap

The correct action is to draw up 2.0 mL of the medication and verify the client using their name and date of birth.
Administering 2.0 mL2.0\text{ mL} of phenytoin correctly delivers the required 50 mg50\text{ mg} individual dose. Furthermore, verifying the client using two acceptable identifiers (such as name and date of birth) complies with fundamental medication safety rights and scope of practice.

Adım Adım Çözüm

1
Calculate the total daily dose of phenytoin based on the client's weight.
20 kg×5 mg/kg/day=100 mg/day20\text{ kg} \times 5\text{ mg/kg/day} = 100\text{ mg/day}
The prescription is weight-based, so the total daily requirement must be established first.
2
Determine the amount required for a single dose.
100 mg÷2 doses=50 mg/dose100\text{ mg} \div 2\text{ doses} = 50\text{ mg/dose}
The prescription specifies that the daily dose is to be given in two equally divided doses.
3
Calculate the liquid volume needed to deliver the single dose using the supplied concentration (125 mg/5 mL125\text{ mg}/5\text{ mL}).
50 mg×(5 mL/125 mg)=2.0 mL50\text{ mg} \times (5\text{ mL} / 125\text{ mg}) = 2.0\text{ mL}
This converts the ordered milligram amount into a measurable milliliter volume.
4
Identify the standard safety requirements for medication administration.
Use two unique identifiers (e.g., name and date of birth).
Safe pharmacological practice prohibits using environmental markers like room or bed numbers to identify clients.

A practical nurse is caring for a client who is 24 hours postoperative following a right total knee arthroplasty. The client reports leg swelling and asks the nurse to place a pillow directly under the right knee for comfort. Which action should the nurse take?

Cevabı ve açıklamayı göster

Cevap: Elevate the right leg by placing a pillow under the lower calf and ankle, ensuring the knee remains fully extended.

Cevap

Elevate the right leg by placing a pillow under the lower calf and ankle, ensuring the knee remains fully extended.
Following a total knee arthroplasty, the primary basic care goals are to reduce edema and prevent flexion contractures. Elevating the leg by placing pillows under the lower calf and ankle allows for venous return while keeping the new knee joint straight and fully extended.

Adım Adım Çözüm

1
Analyze the client's request for comfort measures.
The client requested a pillow directly under the right knee for swelling and comfort.
Understanding the client's specific request helps the nurse determine if the intervention is safe and aligns with postoperative protocols.
2
Evaluate the safety of the requested position.
Placing a pillow directly under the knee is contraindicated post-total knee arthroplasty.
Knee flexion during the postoperative period can lead to flexion contractures, which severely limit future mobility and joint function.
3
Determine the appropriate alternative basic care intervention.
The nurse must elevate the leg to address the swelling while keeping the knee completely straight.
Supporting the lower calf and ankle elevates the extremity to promote venous return, safely managing the edema while maintaining the required knee extension.

Anahtar Kavram

Proper postoperative positioning for total knee arthroplasty emphasizes maintaining knee extension to prevent flexion contractures while appropriately managing edema.

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.
