Cevabı ve açıklamayı göster

Cevap

The client should first assume a tripod position, shift weight onto the crutches, step up with the unaffected left leg, transfer weight to that left leg, and finally bring the crutches and affected right leg up.
When ascending stairs with axillary crutches, the core principle is to lead with the strong leg (often remembered as 'up with the good'). The client must first establish balance in a tripod stance and support their weight entirely on the crutches. This enables the strong, unaffected leg to step up first and provide the necessary power to lift the body's mass. Once the weight is safely transferred to the strong leg on the higher step, the crutches and the affected leg can follow together without bearing weight.

Adım Adım Çözüm

1
Assume the tripod position facing the bottom of the stairs.
A stable base of support is established.
Safety requires a solid foundation before initiating a complex transfer.
2
Shift body weight securely onto the handgrips of both crutches.
Weight is offloaded from the lower extremities.
This allows the client to freely lift the unaffected leg without losing balance.
3
Advance the unaffected left leg up onto the next stair tread.
The strong leg is positioned on the higher step.
The unaffected leg must lead the upward movement to provide lifting power.
4
Transfer body weight from the crutches to the unaffected left leg.
The center of gravity is moved to the higher step.
This stabilizes the body on the new step and frees the crutches to be moved.
5
Bring both crutches and the non-weight-bearing right leg up to the stair.
The sequence for one step is completed.
The crutches always move with the affected leg to maintain non-weight-bearing status and provide continuous support.

A practical nurse is preparing to administer a combination of regular insulin and neutral protamine Hagedorn (NPH) insulin to a client with diabetes mellitus. Arrange the following steps for preparing the mixed insulin injection in the correct chronological order.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct chronological sequence is to roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
The 'clear before cloudy' procedure is a standard pharmacological safety protocol. It ensures that the short-acting (clear) regular insulin is not contaminated by the intermediate-acting (cloudy) NPH insulin. Contamination would unpredictably change the pharmacokinetics of the regular insulin remaining in the vial.

Adım Adım Çözüm

1
Roll the NPH insulin vial.
The intermediate-acting insulin suspension is thoroughly mixed.
NPH is a suspension that settles when standing; rolling mixes it without creating bubbles that could lead to inaccurate dosing.
2
Inject air into the NPH insulin vial and remove the needle.
The NPH vial is pressurized.
Injecting air equal to the prescribed dose prevents a vacuum from forming when the medication is withdrawn later.
3
Inject air into the regular insulin vial and keep the needle inserted.
The regular insulin vial is pressurized and ready for withdrawal.
Pressurizing the vial allows the medication to flow easily into the syringe.
4
Invert the regular insulin vial and withdraw the prescribed dose.
The clear insulin is loaded into the syringe.
Drawing the clear insulin first ensures that no cloudy NPH insulin can accidentally enter and contaminate the regular insulin vial.
5
Insert the needle into the NPH vial and withdraw the prescribed dose.
The exact total volume of mixed insulin is achieved.
The cloudy insulin is added last to complete the mixture, ensuring the 'clear before cloudy' safety principle is maintained.

A practical nurse (PN) is reviewing the morning data for a 72-year-old client who is 24 hours post-operative following a right total hip arthroplasty. The client is scheduled to receive a morning dose of subcutaneous enoxaparin.

Assessment ParameterPreoperative BaselineCurrent Morning Data
Blood Pressure138/82 mm Hg104/62 mm Hg
Heart Rate76 beats/min98 beats/min
Hemoglobin13.5 g/dL10.1 g/dL

The client reports feeling dizzy when sitting on the edge of the bed and rates incisional pain as a 4 on a 0 to 10 scale. Based on these findings, which action represents the most appropriate risk reduction strategy for the PN to take?

Cevabı ve açıklamayı göster

Cevap: Withhold the subcutaneous enoxaparin and immediately notify the registered nurse of the client's clinical trends.

Cevap

The most appropriate action is to withhold the subcutaneous enoxaparin and immediately notify the registered nurse of the client's clinical trends.
The client is demonstrating subtle signs of early hypovolemic shock and active bleeding, evidenced by a 3.4 g/dL drop in hemoglobin, a significant decrease in blood pressure from baseline, compensatory tachycardia, and orthostatic dizziness. Administering an anticoagulant like enoxaparin in the presence of active bleeding poses a severe, life-threatening risk. The priority for the practical nurse is to reduce risk by withholding the contraindicated medication and immediately escalating the findings to the registered nurse for intervention.

Adım Adım Çözüm

1
Analyze the vital sign trends from baseline to current.
Blood pressure has dropped significantly (narrowing pulse pressure) and heart rate has increased by 22 beats per minute.
Absolute vital signs may appear normal, but a significant deviation from baseline indicates physiological stress or compensation.
2
Evaluate the laboratory data changes.
Hemoglobin dropped by 3.4 g/dL in 24 hours.
A rapid drop in hemoglobin, even if the current value is not critically low, signifies substantial acute blood loss.
3
Interpret the clinical symptoms in context.
Dizziness upon sitting up indicates orthostatic hypotension.
Orthostatic changes strongly support a fluid volume deficit, correlating with the suspected blood loss.
4
Synthesize findings to identify the primary risk.
The client is exhibiting early compensatory signs of hypovolemic shock due to internal postoperative bleeding.
Recognizing early shock is critical to preventing progression to irreversible organ damage.
5
Determine the safest nursing action within the PN scope of practice.
The PN decides to withhold the scheduled anticoagulant and escalate the findings.
Administering enoxaparin would exacerbate the active bleeding. The PN must mitigate this risk by holding the medication and reporting the unstable condition to the RN.

A client returns to the medical-surgical unit immediately after a percutaneous liver biopsy. To minimize the risk of bleeding from the puncture site, which of the following positions should the practical nurse place the client in?

Cevabı ve açıklamayı göster

Cevap: Right side-lying position with a folded towel under the puncture site

Cevap

Right side-lying position with a folded towel under the puncture site
Following a percutaneous liver biopsy, the standard of care is to place the client in a right side-lying position, often with a small pillow or folded towel directly under the puncture site. The liver is a highly vascular organ located on the right side of the body. This specific position strategically uses the client's own body weight to apply direct, continuous pressure to the biopsy site, significantly reducing the risk of postoperative hemorrhage.

Adım Adım Çözüm

1
Identify the anatomical location of the liver and the primary complication associated with a liver biopsy.
The liver is a highly vascular organ located in the right upper quadrant of the abdomen, making hemorrhage the most significant post-procedure risk.
Understanding the anatomy and potential risks dictates the specific nursing interventions required immediately after the procedure.
2
Determine the optimal client position that minimizes the identified risk.
The client must be placed on their right side to create a tamponade effect.
Placing the client on their right side allows their own body weight to compress the liver against the abdominal wall and mattress, providing direct hemostasis.

Cevap: A morning platelet count that has decreased from 210,000/mm3210,000/\text{mm}^3 to 95,000/mm395,000/\text{mm}^3.

Cevap

The morning platelet count that has decreased from 210,000/mm3210,000/\text{mm}^3 to 95,000/mm395,000/\text{mm}^3.
The correct answer identifies the significant decrease in the platelet count. A drop in platelets by more than 50% or a decline below 150,000/mm3150,000/\text{mm}^3 in a client receiving heparin is a primary indicator of heparin-induced thrombocytopenia (HIT). This paradoxical immune reaction causes widespread microthrombi and severe vascular complications. It requires immediate escalation to the registered nurse so the heparin infusion can be stopped promptly.

Adım Adım Çözüm

1
Identify the primary pharmacological risks associated with continuous intravenous heparin therapy.
The major risks include systemic hemorrhage and a paradoxical immune response known as heparin-induced thrombocytopenia (HIT).
Understanding potential complications dictates which assessment data must be prioritized.
2
Evaluate the provided assessment and laboratory data against expected therapeutic ranges.
The aPTT of 68 seconds68\text{ seconds} is therapeutic. The vital signs are stable. Small ecchymoses are expected side effects. However, the platelet count has dropped by over 50%.
Differentiating between expected therapeutic effects and critical adverse reactions is required to identify the true risk.
3
Determine which finding necessitates immediate escalation to the registered nurse.
The severe drop in platelets indicates suspected HIT, meaning the heparin must be stopped immediately to prevent life-threatening thrombotic events.
Practical nurses must promptly recognize and report critical laboratory shifts that threaten client safety.

A practical nurse is caring for a client in a rehabilitation facility who is 48 hours postoperative following a right below-the-knee amputation. To prevent flexion contractures, which of the following positioning strategies should the nurse implement?

Cevabı ve açıklamayı göster

Cevap: Place the client in a prone position for 20 to 30 minutes several times a day.

Cevap

Place the client in a prone position for 20 to 30 minutes several times a day.
Following a lower extremity amputation, placing the client in a prone position for 20 to 30 minutes several times a day is the correct standard of basic care. This specific position extends and stretches the flexor muscles of the hip and knee, preventing the development of flexion contractures. Preventing these contractures is essential because they are a major complication that can permanently inhibit the proper fitting and use of a prosthetic device.

Adım Adım Çözüm

1
Identify the time elapsed since the surgery (48 hours) and the specific complication to prevent (flexion contractures).
After the first 24 postoperative hours, the primary clinical focus shifts from edema prevention to contracture prevention.
Understanding the timeline is critical because basic care and positioning rules for amputations change significantly after the first 24 hours.
2
Evaluate the anatomical impact of each positioning strategy on the client's hip and knee joints.
Prone positioning physically stretches the hip flexor muscles, preventing them from tightening and shortening.
Flexion contractures can severely impair the client's future ability to be fitted for and successfully use a prosthetic limb.

Cevap: Support the client's head and neck with a pillow when assisting with position changes; Apply a prescribed ice collar to the anterior neck area; Offer small sips of cool water and gentle oral hygiene once the gag reflex is confirmed

Cevap

The correct interventions are supporting the head and neck during movement, applying an ice collar, and providing cool fluids with oral hygiene after verifying the gag reflex.
Following a thyroidectomy, basic care focuses on minimizing tension on the surgical incision and reducing swelling. Supporting the head and neck prevents strain on the sutures during movement. Applying an ice collar provides localized analgesia and decreases edema that could otherwise threaten the airway. Providing oral care and cool liquids promotes mucosal hydration and comfort without causing the thermal vasodilation that warm liquids might provoke.

A practical nurse is assisting a client with a meal who is recovering from a recent cerebrovascular accident (CVA). The client has right-sided hemiplegia and has been diagnosed with oropharyngeal dysphagia. The dietary prescription is a pureed diet with honey-thick liquids. Which action should the practical nurse implement to ensure client safety and comfort during the feeding?

Cevabı ve açıklamayı göster

Cevap: Instruct the client to flex the neck and tuck the chin downward toward the chest when swallowing.

Cevap

The practical nurse should instruct the client to use a chin-tuck maneuver (flexing the neck downward) while swallowing to protect the airway and prevent aspiration.
The chin-tuck maneuver is an evidence-based compensatory strategy for clients with oropharyngeal dysphagia. Flexing the neck and tucking the chin downward before swallowing narrows the laryngeal opening, widens the vallecular space, and pushes the epiglottis backward to protect the airway, significantly reducing the risk of aspiration. This is a primary basic care and comfort priority for stroke recovery.

Adım Adım Çözüm

1
Analyze the client's physiological deficits and risks based on the clinical presentation.
The client has right-sided paralysis and dysphagia, meaning they have impaired swallowing mechanics and a high risk of airway compromise (aspiration).
Identifying the specific impairments dictates which compensatory feeding strategies are required to maintain ABCs (Airway, Breathing, Circulation).
2
Select the appropriate evidence-based intervention for airway protection during oral intake.
The chin-tuck maneuver is identified as the safest technique, as it anatomically protects the trachea.
Flexing the neck widens the vallecular space and forces the epiglottis backward, mechanically blocking the airway during the swallow.

Cevap

The correct actions include maintaining the head of the bed elevated at 30 to 45 degrees during feeding, applying a moisture barrier cream after liquid stools, and pausing the feeding pump before lowering the head of the bed for repositioning.
Appropriate basic care for a client receiving continuous enteral nutrition includes keeping the head of the bed elevated between 30 and 45 degrees to prevent aspiration, and strictly pausing the feeding pump whenever the bed must be lowered to reposition the client. Additionally, applying a moisture barrier cream is a fundamental comfort and skin protection measure for clients experiencing frequent liquid stools.

Adım Adım Çözüm

1
Analyze the client's airway and aspiration risks associated with continuous enteral feeding.
Identified that the client requires a 30 to 45-degree head of bed elevation, and that feedings must be paused whenever the bed is lowered.
Enteral formula can easily reflux into the airway if gravity is not utilized, causing aspiration pneumonia.
2
Evaluate the client's skin integrity risk due to frequent liquid stools.
Determined that perineal skin care with a moisture barrier cream is required.
Liquid stool is highly acidic and caustic to the skin, necessitating immediate and ongoing protective basic care.
3
Review the incorrect interventions for safety and scope of practice violations.
Eliminated options that violate ABC prioritization (giving opioids before respiratory assessment), bypass restraint alternatives, or position the client dangerously flat during feeding.
Nursing care must prioritize ABCs (Airway, Breathing, Circulation) and adhere strictly to least-restrictive restraint guidelines.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence for obtaining a wound culture is to first remove the soiled dressing, then cleanse the wound with normal saline, next swab the viable tissue, followed by placing the swab in the culture tube, and finally labeling the specimen at the bedside.
Following the correct sequence ensures that the wound culture identifies the actual pathogen causing the infection rather than surface flora, and prevents cross-contamination or misidentification of the specimen.

Adım Adım Çözüm

1
Remove the soiled wound dressing and dispose of it in the appropriate receptacle.
The wound bed is exposed for assessment and collection.
The old dressing contains surface bacteria and exudate that are not representative of the true infection and must be removed first.
2
Cleanse the wound bed with prescribed sterile normal saline to remove surface exudate.
Surface exudate and colonizing flora are washed away.
Culturing uncleaned exudate often yields colonizing bacteria rather than the pathogen responsible for the tissue infection, which can lead to inappropriate antibiotic therapy.
3
Rotate the sterile culture swab over an area of clean, viable granulation tissue.
The specimen is collected from actively infected, living tissue.
Pathogens grow best in viable tissue; swabbing slough or necrotic tissue may yield inaccurate diagnostic results.
4
Insert the swab into the sterile culture tube without touching the outside of the container.
The specimen is secured in the transport medium.
This maintains the sterility of the container's exterior, protecting healthcare workers and laboratory personnel from exposure to the pathogen.
5
Label the specimen container in the presence of the client before sending it to the laboratory.
The specimen is accurately identified with the correct client information.
Labeling at the bedside immediately after collection eliminates the risk of mixing up specimens and ensures accurate diagnostic reporting.

Cevap: The client's heart rate has increased from a preoperative baseline of 78 beats/min to 116 beats/min, with a current blood pressure of 104/68 mm Hg.; The client exhibits new-onset restlessness, repeatedly pulling at the bedsheets and asking to get out of bed.; The client's most recent laboratory results show a hemoglobin level of 9.4 g/dL (94 g/L), down from a preoperative level of 13.8 g/dL (138 g/L).

Cevap

The findings requiring immediate escalation are the increasing heart rate with borderline blood pressure, the new-onset restlessness, and the significant drop in hemoglobin.
The correct selections all point to a developing postoperative hemorrhage and subsequent hypovolemic shock. A dropping hemoglobin level confirms blood loss, while the compensatory tachycardia and new-onset restlessness (indicating cerebral hypoxia) are classic early signs of shock that demand immediate RN and provider intervention.

Adım Adım Çözüm

1
Analyze the client's postoperative timeframe and surgical risk factors.
The client is 12 hours post-abdominal surgery, placing them at high risk for hemorrhage, hypovolemic shock, and respiratory complications.
Identifying the highest risk timeframes directs the focus of the clinical assessment.
2
Evaluate the vital signs, laboratory data, and neurological status for signs of hypoperfusion.
The client demonstrates tachycardia, a significant hemoglobin drop, and new-onset restlessness.
These combined findings are classic indicators of active internal bleeding and early compensatory shock.
3
Differentiate critical complications from expected postoperative findings.
Incisional pain, a beefy red stoma, and a urine output of 35 mL/hr are expected or adequate findings that do not require emergency escalation.
Safe prioritization requires recognizing what constitutes an immediate threat to life versus routine postoperative recovery.

Cevap: Withhold the scheduled dose and immediately report the laboratory findings to the registered nurse.

Cevap

The practical nurse should withhold the scheduled dose of warfarin and immediately report the critically high INR finding to the registered nurse.
For a client taking warfarin for atrial fibrillation, the standard therapeutic International Normalized Ratio (INR) is between 2.0 and 3.0. An INR of 5.8 is critically high and indicates excessive anticoagulation. The practical nurse must prioritize client safety by withholding the medication to prevent hemorrhage and immediately reporting the finding to the registered nurse or healthcare provider.

Adım Adım Çözüm

1
Evaluate the client's morning laboratory results prior to medication administration.
The client has an INR of 5.8.
Warfarin dosage is directly guided by the INR level, which must be checked to ensure administration is safe.
2
Compare the client's INR to the expected therapeutic range.
The result of 5.8 is critically high, as the standard therapeutic range is typically 2.0 to 3.0 for a client with atrial fibrillation.
Recognizing critical lab values is essential to prevent severe medication toxicity.
3
Determine the appropriate nursing intervention based on the practical nurse scope of practice.
The medication must be withheld and the registered nurse or provider must be notified.
Administering the medication would cause harm, and abnormal findings must be escalated to the supervising nurse.

Cevap: Notify the registered nurse immediately about the client's vital signs and symptoms.

Cevap

Notify the registered nurse immediately about the client's vital signs and symptoms.
The correct action is to immediately notify the registered nurse. The client's tachycardia, hypotension, and dizziness 44 hours after major abdominal surgery are early signs of hypovolemic shock or internal bleeding. Prompt escalation is necessary to initiate life-saving interventions such as fluid resuscitation or returning to the operating room.

Adım Adım Çözüm

1
Analyze the client's vital signs and reported symptoms.
Tachycardia, hypotension, and dizziness are identified.
These are early clinical indicators of hypovolemia or hemorrhage following major abdominal surgery.
2
Prioritize the nursing response based on the LPN scope of practice.
The practical nurse determines that immediate escalation is required.
Suspected shock is a life-threatening complication that requires RN assessment and provider intervention.

Cevap: Assist the client into a prone position for 20 to 30 minutes multiple times a day.; Wash the intact skin around the residual limb gently with mild soap and warm water.; Guide the client through active range-of-motion exercises for the unaffected extremities.

Cevap

The correct interventions are assisting the client into a prone position periodically, washing the intact skin of the residual limb with mild soap, and guiding the client through active range-of-motion exercises for the unaffected extremities.
The correct basic care measures focus on preventing complications and promoting comfort. Assisting the client into a prone position several times a day prevents hip flexion contractures, which are a major risk following an amputation. Gentle hygiene of the intact skin around the residual limb maintains skin integrity and promotes comfort. Additionally, guiding the client through active range-of-motion exercises for unaffected extremities preserves the mobility and strength required for future rehabilitation.

Adım Adım Çözüm

1
Analyze the client's postoperative timeframe (48 hours) and surgical procedure (below-the-knee amputation) to determine safe positioning and mobility requirements.
After 24 hours, interventions must strictly avoid promoting hip or knee flexion to prevent permanent contractures.
Contractures can severely delay or prevent the successful fitting and use of a prosthetic limb.
2
Identify non-pharmacological comfort measures and basic hygiene routines appropriate for the healing residual limb.
Gentle washing of intact skin and acknowledging phantom limb pain are prioritized.
Maintaining cleanliness prevents skin breakdown, while validating the client's pain experience supports both physiological comfort and psychosocial integrity.
3
Select all options that align with safe positioning, mobility maintenance, and therapeutic communication within the practical nurse's scope of basic care.
Prone positioning, gentle hygiene, and active range-of-motion for unaffected limbs are selected as correct.
These actions directly fulfill the learning objective of providing basic care and comfort while preventing common postoperative complications.

Cevap: Verifying two distinct client identifiers by checking the identification band prior to administering a prescribed oral analgesic.; Notifying the registered nurse (RN) immediately regarding a morning serum potassium result of 2.8 mEq/L2.8\text{ mEq/L} (2.8 mmol/L2.8\text{ mmol/L}).; Escalating care to the RN when the client's resting heart rate increases to 118 beats/min118\text{ beats/min} with a blood pressure of 92/56 mm Hg92/56\text{ mm Hg}.

Cevap

The correct actions include verifying two client identifiers before medication administration, immediately notifying the RN of a critical potassium level, and escalating care for borderline vital signs indicating potential shock.
Safe practical nursing care requires strict adherence to risk reduction principles. This includes mandatory safety checks like verifying two distinct client identifiers. Furthermore, the practical nurse plays a critical role in early complication detection by identifying and immediately escalating critical laboratory values (such as a severely low potassium level of 2.8 mEq/L2.8\text{ mEq/L}, which risks cardiac dysrhythmias) and subtle signs of impending complications (such as unexpected tachycardia and hypotension, which are early indicators of hypovolemic shock or hemorrhage).

Adım Adım Çözüm

1
Analyze the client's post-operative status and identify the practical nurse's scope of practice.
The client is at risk for post-operative complications, requiring vigilant monitoring and interventions within the PN scope.
Reduces risk potential by recognizing boundaries and critical physiological changes.
2
Evaluate each potential action for safety, physiological rationale, and appropriate delegation.
Identifying patients correctly, reporting critical labs (hypokalemia), and recognizing early shock signs are safe, necessary actions.
These actions directly reduce the risk of adverse outcomes and fall within the PN scope of practice.
3
Identify and exclude contraindicated actions.
IV push medications are out of scope, knee pillows risk DVT, and ignoring hypoxia violates ABC prioritization.
These actions increase risk potential and represent unsafe clinical practice.

An interdisciplinary care team has established a treatment plan for a client admitted with acute decompensated heart failure and atrial fibrillation. The pharmacological prescriptions include a continuous intravenous heparin infusion, intravenous push furosemide, oral spironolactone, and topical nitroglycerin ointment. Which medication administration action should the practical nurse identify as being within their scope of practice?

Cevabı ve açıklamayı göster

Cevap: Apply the topical nitroglycerin ointment to a hairless area of the chest using a dose-measuring applicator while wearing clean gloves.

Cevap

The practical nurse should safely apply the topical nitroglycerin ointment to the client using a dose-measuring applicator while wearing clean gloves.
Applying topical medications, such as nitroglycerin ointment, is a foundational skill within the practical nurse scope of practice. Using a dose-measuring applicator ensures correct dosing, and wearing clean gloves is a critical safety measure to prevent the nurse from absorbing the medication and experiencing adverse effects like hypotension and a severe headache.

Adım Adım Çözüm

1
Evaluate the order for the continuous intravenous heparin infusion.
Determine that titrating this infusion is outside the practical nurse scope.
Titrating high-alert continuous infusions based on laboratory results requires the advanced clinical judgment of a registered nurse.
2
Evaluate the order for intravenous push furosemide.
Determine that administering intravenous push medications is not permitted for the practical nurse.
Intravenous push medications carry high risks, act rapidly, and require immediate registered nurse assessment.
3
Evaluate the medication verification scenario regarding the oral spironolactone.
Determine that bypassing barcode scanning violates safe medication administration principles.
Two client identifiers must be verified before every single medication administration to prevent errors.
4
Evaluate the order for the topical nitroglycerin ointment.
Determine that applying topical medications is a safe, standard procedure for the practical nurse.
Wearing gloves is a critical safety step to prevent unintended self-administration and systemic vasodilation in the nurse.
