Cevap

The correct sequence is to first stop the feeding, then position the client laterally, suction the airway, administer oxygen, and finally notify the registered nurse.
When a client receiving continuous enteral feeding exhibits signs of acute aspiration (such as coughing, dyspnea, and cyanosis), the practical nurse must follow a strict prioritization sequence. The absolute first priority is to stop the source of the aspiration by turning off the feeding pump; failing to do so allows further fluid to compromise the lungs. Second, the airway must be protected physically by turning the client to a lateral position, which uses gravity to drain secretions and prevent further inhalation. Third, the nurse suctions the oropharynx to actively clear the airway of aspirated formula. Fourth, with a clear airway established, supplemental oxygen is administered to treat the resulting hypoxia. Finally, after resolving the immediate life-threatening crisis at the bedside, the nurse reports the event to the registered nurse (RN) to coordinate ongoing evaluation, such as diagnostic imaging and provider notification.

Adım Adım Çözüm

1
Stop the continuous enteral feeding pump.
The source of the aspiration is halted.
Prior to addressing the airway directly, the nurse must eliminate the active cause of the aspiration to prevent further respiratory compromise.
2
Turn the client to a lateral, side-lying position.
Secretions and formula are drained away from the trachea.
Positioning utilizes gravity to protect the airway and prevent further inhalation of gastric contents.
3
Suction the client's oropharynx.
The airway is cleared of visible formula and respiratory secretions.
Direct removal of aspirated material is necessary to restore airway patency once the client is positioned securely.
4
Administer supplemental oxygen as prescribed.
Oxygenation levels are improved, resolving cyanosis.
After securing a patent airway, treating the hypoxia caused by the aspiration event is the next physiological priority.
5
Report the acute event to the registered nurse (RN).
Further medical evaluation and interventions are initiated.
Once the client is stabilized from the immediate threat, the RN must be notified to coordinate a chest radiograph and healthcare provider notification.

A practical nurse (PN) is caring for an older adult client who is being treated for pneumonia. The client suddenly becomes restless, reports feeling short of breath, and has an oxygen saturation of 87% on room air. What is the priority action for the PN?

Cevabı ve açıklamayı göster

Cevap: Elevate the head of the bed and administer prescribed supplemental oxygen.

Cevap

Elevate the head of the bed and administer prescribed supplemental oxygen.
The correct action directly addresses the client's acute hypoxia. Restlessness and a low oxygen saturation (87%) are classic signs of inadequate oxygenation. Elevating the head of the bed facilitates maximum lung expansion, and providing supplemental oxygen directly treats the physiological deficit, perfectly aligning with the Airway, Breathing, Circulation (ABC) prioritization framework.

Adım Adım Çözüm

1
Identify the client's primary clinical problem based on the provided data.
The client is experiencing sudden restlessness, shortness of breath, and an oxygen saturation of 87%, which indicates acute hypoxia.
Recognizing signs of physiological deterioration is the first step in making safe clinical judgments.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
The client has a severe breathing and gas exchange issue that requires immediate, life-saving intervention.
Airway and breathing issues take precedence over routine assessments or secondary symptoms like anxiety.
3
Determine the most appropriate initial nursing action.
Positioning the client upright and applying oxygen directly addresses the breathing compromise.
These actions immediately improve oxygenation and ventilation, stabilizing the client before further assessments are performed.

A practical nurse (PN) is assigned to care for a 74-year-old client who receives a daily scheduled dose of oral lithium carbonate. During morning rounds, the client is acutely disoriented, exhibits a coarse bilateral hand tremor, and reports severe nausea. The laboratory report from earlier this morning indicates a serum lithium level of 1.9 mEq/L. Which of the following actions should the PN take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled dose of lithium carbonate and immediately report the findings to the registered nurse.

Cevap

The correct action is to withhold the scheduled dose of lithium carbonate and immediately notify the registered nurse.
A serum lithium level of 1.9 mEq/L is well above the therapeutic range (0.6 to 1.2 mEq/L) and indicates severe toxicity. The client's symptoms of acute disorientation, coarse tremors, and severe nausea strongly correlate with this dangerous drug level. The priority and safest action within the practical nurse's scope is to hold the next dose to prevent worsening toxicity and to immediately escalate the finding to the registered nurse for further medical orders.

Adım Adım Çözüm

1
Analyze the client's serum lithium level.
The level is 1.9 mEq/L, which exceeds the normal therapeutic range of 0.6 to 1.2 mEq/L.
Identifying that the laboratory value represents severe toxicity is the necessary first step in clinical decision-making.
2
Correlate the laboratory data with the client's clinical manifestations.
The acute disorientation, coarse hand tremor, and severe nausea are classic neurological and gastrointestinal signs of advanced lithium toxicity.
Clinical signs confirm the urgency of the elevated laboratory value and rule out a false laboratory reading.
3
Determine the appropriate intervention within the practical nurse scope of practice.
The medication must be withheld to prevent further harm, and the registered nurse must be notified immediately to escalate care.
The PN is responsible for safe medication administration, which includes withholding unsafe doses and reporting critical changes in client status to the supervising RN.

Cevap: Alert the registered nurse (RN) immediately about the changes in the client's condition.

Cevap

The priority action is to immediately alert the registered nurse (RN) regarding the changes in the client's condition.
The client's presentation of severe diarrhea followed by sudden disorientation, tachycardia (116 beats/min), and hypotension (88/54 mm Hg) strongly indicates hypovolemic shock. Because the client is experiencing a life-threatening circulatory emergency that requires interventions outside the practical nurse's independent scope (such as administering intravenous fluids), the immediate priority is to notify the registered nurse so collaborative emergency care can begin.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client has a weak, rapid pulse (116 beats/min), low blood pressure (88/54 mm Hg), and new-onset disorientation.
Identifying abnormal data is the first step in clinical decision-making.
2
Correlate the findings with the client's history.
Severe diarrhea leads to significant fluid loss, which explains the tachycardia, hypotension, and poor cerebral perfusion (disorientation).

A client is receiving care 72 hours after a right above-the-knee amputation. The client reports a dull ache in the residual limb and asks the practical nurse to place a pillow underneath it for support. Which action should the nurse take?

Cevabı ve açıklamayı göster

Cevap: Explain that elevating the limb on a pillow at this stage increases the risk of developing a hip flexion contracture.

Cevap

The correct action is to explain that elevating the limb on a pillow at this stage increases the risk of developing a hip flexion contracture.
After the first 24 hours following a lower extremity amputation, the residual limb should not be elevated on a pillow. Elevating the limb or maintaining prolonged flexion at this stage significantly increases the risk of developing a hip flexion contracture, which can severely impair future mobility and prosthetic fitting. The nurse must provide education regarding this risk and utilize alternative comfort measures.

Adım Adım Çözüm

1
Identify the type of surgery and the time elapsed.
The client had a right above-the-knee amputation 72 hours (3 days) ago.
Postoperative protocols for amputation change significantly after the first 24 hours.
2
Determine the physiological risks associated with positioning at this stage.
The primary risk after 24 hours is the development of a hip flexion contracture due to prolonged flexion of the joint.
Contractures can severely limit mobility and complicate or prevent the successful fitting of a prosthesis.
3
Evaluate the client's request against safety guidelines.
Placing a pillow under the limb promotes hip flexion and is strictly contraindicated at 72 hours.
The nurse must prioritize long-term mobility and prevent complications over the requested short-term comfort measure.
4
Select the appropriate nursing intervention.
The nurse should deny the pillow request while providing education on the risk of contractures.

The correct sequence is: Assume the tripod position, transfer weight to the crutches, step up with the unaffected leg, shift weight to the unaffected leg, and finally bring the crutches and affected leg up.
When ascending stairs with crutches, the client must follow the safety principle of 'up with the good'. The client begins in a stable tripod position and transfers weight to the crutch handles. The unaffected (strong) leg is then placed on the step above. Once the strong leg is firmly planted, the client shifts their weight onto it. Finally, the client uses the strong leg to elevate the body, bringing the crutches and the affected (weak) leg up to the same step. This sequence ensures that the strong leg does the work of lifting the body against gravity.

An older adult client is recovering on the orthopedic unit on the first postoperative day following a right total hip arthroplasty via a posterior approach. When assisting the client with morning hygiene and bed repositioning, which action by the practical nurse is most appropriate?

Cevabı ve açıklamayı göster

Cevap: Maintaining an abduction wedge between the client's legs while turning them onto their left side

Cevap

Maintaining an abduction wedge between the client's legs while turning them onto their left side is the most appropriate action.
Following a total hip arthroplasty via a posterior approach, the client is at high risk for hip dislocation if the hip is adducted, internally rotated, or flexed beyond 90 degrees. Using an abduction wedge between the legs prevents adduction and internal rotation, especially when turning the client onto their non-operative (left) side, thereby maintaining proper joint alignment and safety during basic care.

Adım Adım Çözüm

1
Identify the surgical procedure and the specific approach used.
The client had a right total hip arthroplasty using a posterior approach.
Different surgical approaches have distinct postoperative positioning restrictions that dictate basic care.
2
Recall the positioning precautions specific to a posterior approach total hip arthroplasty.
To prevent prosthesis dislocation, the client must avoid hip flexion greater than 90 degrees, avoid adduction (crossing the legs over the midline), and avoid internal rotation.
Basic care and comfort measures must be adapted to adhere strictly to these physical safety limits.
3
Evaluate each nursing action against the identified precautions.
Elevating the bed to 90 degrees and flexing the hip past 90 degrees to wash the foot both violate the flexion precaution. Placing a pillow under the knee poses a circulatory risk (deep vein thrombosis). Using an abduction wedge while turning maintains proper alignment and prevents adduction.
This confirms that using the abduction wedge is the only safe and appropriate action among the choices.

Cevabı ve açıklamayı göster

Cevap

The correct chronological sequence prioritizes environmental safety first, followed by physiological adaptation (dangling), equipment application (gait belt), biomechanical stabilization (bracing the weak leg), standing utilizing the strong side, and finally pivoting to safely complete the transfer.
Executing a safe transfer for a client with hemiplegia requires a highly systematic approach based on biomechanical principles. The sequence must begin with securing the environment by placing the chair on the client's strong (right) side. Next, physiological safety is ensured by having the client dangle to prevent orthostatic hypotension. Once seated safely, the gait belt is applied to provide the nurse with a safe handling point. Before standing, the nurse must physically brace the weak (left) leg to prevent it from buckling under the client's weight. The client then actively participates by pushing up with their strong (right) arm. Finally, a controlled pivot leads the client to the chair, where they reach for the armrest to guide a safe descent.

Adım Adım Çözüm

1
Prepare the wheelchair on the client's right side and lock brakes.
The environment is secure and oriented for a strong-side transfer.
Clients with hemiplegia must always transfer toward their unaffected side to utilize their intact muscle strength and coordination.
2
Assist the client to dangle and assess for dizziness.
The client adapts to the upright posture safely.
Moving a client from supine to standing too quickly risks orthostatic hypotension, which could cause a sudden fall during the transfer.
3
Apply a gait belt securely around the waist.
A safe handling interface is established.
A gait belt provides a center-of-gravity hold, preventing the nurse from lifting the client by their flaccid or weak arms.
4
Brace the client's left knee.
The hemiplegic leg is externally stabilized.
The affected leg lacks the motor control to support body weight independently and will collapse unless physically blocked by the nurse's knee.
5
Have the client push off the bed with their right hand to stand.
The client reaches a standing position.
Pushing off a solid surface (the mattress) with the unaffected arm maximizes the client's functional ability and reduces the physical load on the nurse.
6
Pivot toward the chair and have the client reach for the armrest.
The transfer is completed safely.
Pivoting as a single unit maintains alignment, and grasping the armrest provides necessary support to control the sitting motion.

Anahtar Kavram

Safe mobility and transfer techniques for clients with hemiplegia require utilizing the unaffected side for weight-bearing and spatial orientation, while physically supporting the affected side.

Cevap: Elevate the head of the bed to a semi-Fowler's position.; Provide a firm pillow for the client to splint the chest incision when coughing.; Encourage early, gentle range-of-motion exercises for the left arm and shoulder.

Cevap

The correct interventions are elevating the head of the bed to a semi-Fowler's position, providing a firm pillow for splinting the incision, and encouraging early range-of-motion exercises for the operative arm and shoulder.
The correct interventions focus on maximizing respiratory function and managing localized pain. Elevating the head of the bed allows gravity to pull the diaphragm downward, maximizing lung expansion. Providing a pillow for splinting minimizes incision pain during necessary coughing, making the client more willing to clear secretions. Finally, encouraging gentle range-of-motion exercises for the arm and shoulder on the operative side prevents joint stiffness and contractures, which are common sources of delayed post-operative pain after chest surgery.

Adım Adım Çözüm

1
Identify the surgical procedure and its physiological impact.
The client had a left pneumonectomy, meaning the entire left lung was removed. The client relies entirely on the remaining right lung for oxygenation and gas exchange.
Understanding the anatomical changes is required to determine safe positioning and care.
2
Determine appropriate positioning to optimize ventilation.
A semi-Fowler's position is indicated. Positioning on the unoperated side must be avoided.
Gravity helps pull the diaphragm downward in semi-Fowler's, maximizing the expansion of the remaining lung. Laying on the good lung would compress it and limit ventilation.
3
Select basic comfort measures that prevent post-operative complications specific to thoracic surgery.
Splinting the incision and performing range-of-motion exercises are selected.
Splinting controls pain to allow for vital airway clearance. Arm movement prevents 'frozen shoulder' contractures on the operative side.
4
Evaluate the remaining options for potential risks.
Lowering the head of the bed flat and suppressing coughs are identified as unsafe actions.
Both actions prioritize secondary concerns (shearing forces, incision tension) over primary airway and breathing needs (ABC prioritization).

Cevap: Pause the continuous enteral feeding for 11 to 2 hours2\text{ hours} prior to and following the administration of the medication.

Cevap

The correct action is to pause the continuous enteral feeding for 11 to 2 hours2\text{ hours} before and after administering the liquid phenytoin.
Enteral feeding formulas contain high amounts of proteins that strongly bind to phenytoin, significantly decreasing its absorption in the gastrointestinal tract. To prevent subtherapeutic serum drug levels and subsequent breakthrough seizures, the practical nurse must pause the continuous feeding for 11 to 2 hours2\text{ hours} before and after administering the scheduled medication dose. The tube must also be flushed adequately with water before and after the dose.

Adım Adım Çözüm

1
Identify the prescribed medication and the client's current method of nutritional support.
The client is receiving liquid phenytoin and continuous enteral nutrition formula via a gastrostomy tube.
Understanding the concurrent therapies is the essential first step in identifying potential drug-nutrient interactions.
2
Evaluate potential interactions between oral phenytoin and enteral feeding formulas.
Enteral nutrition formulas significantly decrease the gastrointestinal absorption of phenytoin.
Phenytoin binds strongly to the proteins present in the enteral formula, which can lead to subtherapeutic serum drug levels and poor seizure control.
3
Determine the appropriate nursing intervention to prevent the drug-nutrient interaction.
The continuous enteral feeding must be stopped for a specific window of time (11 to 2 hours2\text{ hours}) before and after the medication is given.
This time window allows the stomach to empty, preventing the formula from binding to the medication and ensuring adequate drug absorption.

While reviewing morning laboratory data for a client prescribed furosemide, a practical nurse observes a serum potassium level of 2.8 mEq/L (2.8 mmol/L). What is the most appropriate initial action by the nurse?

Cevabı ve açıklamayı göster

Cevap: Report the laboratory finding to the registered nurse immediately.

Cevap

The practical nurse must report the laboratory finding to the registered nurse immediately.
A serum potassium level of 2.8 mEq/L is considered hypokalemia (normal range: 3.5 to 5.0 mEq/L). Furosemide is a potassium-wasting diuretic that can further lower these levels. Within the legal scope of practice, the practical nurse must immediately report this critical laboratory value to the registered nurse or healthcare provider so the diuretic can be held and appropriate potassium replacement prescribed.

Adım Adım Çözüm

1
Identify the normal range for serum potassium.
The expected normal range for serum potassium is 3.5 to 5.0 mEq/L.
Establishing the baseline is necessary to determine if the client's current value is abnormal.
2
Analyze the client's laboratory value.
The client's level of 2.8 mEq/L indicates severe hypokalemia.
Hypokalemia poses a high risk for life-threatening cardiac dysrhythmias and requires prompt intervention.
3
Determine the appropriate nursing action within the practical nurse scope of practice.
The finding must be immediately escalated to the registered nurse or healthcare provider.
A critical lab value requires medical evaluation and possible medication adjustments that fall under RN or provider responsibility.

An older adult client who recently had a percutaneous endoscopic gastrostomy (PEG) tube placed is receiving continuous enteral nutrition. The client has been incontinent of bowel, and the unlicensed assistive personnel (UAP) requests assistance from the practical nurse to clean the client. The UAP states, "I need to lay the bed completely flat so we can roll him safely without injuring our backs." Which instruction should the practical nurse provide to the UAP?

Cevabı ve açıklamayı göster

Cevap: We must pause the feeding pump before lowering the head of the bed, and wait to restart it until we raise the bed back up.

Cevap

The practical nurse must instruct the UAP to pause the continuous enteral feeding pump before lowering the head of the bed, and to resume the feeding only after the client is repositioned with the head of the bed elevated.
Lowering the head of the bed below 30 degrees while enteral nutrition is infusing significantly increases the risk of regurgitation and pulmonary aspiration. Even with a percutaneous endoscopic gastrostomy (PEG) tube, gravity is necessary to keep stomach contents from refluxing into the esophagus. The standard of nursing care dictates that the feeding must be paused any time the client needs to be laid flat for turning, bed-making, or hygiene, and resumed immediately upon returning the client to a semi-Fowler's position.

Adım Adım Çözüm

1
Identify the primary clinical risk factors presented in the scenario.
The client is receiving continuous enteral feeding via a PEG tube and requires a flat bed position for safe turning and hygiene care.
Recognizing competing priorities (the need for hygiene vs. the risk of aspiration) is essential for safe basic care.
2
Analyze the physiological relationship between patient positioning and enteral feedings.
Gravity is required to keep stomach contents from refluxing into the esophagus; laying the client flat eliminates this protection.
Understanding why the head of the bed must remain elevated at least 30 degrees guides the clinical decision-making process.
3
Determine the safest intervention that accommodates both the hygiene need and the physiological safety requirement.
The feeding must be paused while the bed is flat and immediately resumed once the head of the bed is returned to a safe elevation.
This intervention prevents aspiration while allowing the UAP and nurse to practice safe ergonomics during the linen change.

Cevap: Verify the client's identity by comparing the medication administration record (MAR) to the client's wristband while asking them to state their name and date of birth.; Reinforce previous teaching with the client regarding the importance of consuming potassium-rich foods while taking furosemide.; Withhold the furosemide and promptly report a critically low serum potassium laboratory result to the RN or provider.

Cevap

The correct actions include verifying the client's identity using the MAR and two acceptable identifiers, reinforcing teaching about potassium-rich foods for the prescribed furosemide, and withholding the diuretic while escalating a critically low potassium level to the RN.
Safe medication administration by a practical nurse involves adhering strictly to the medication rights, practicing within the defined legal scope, and applying clinical knowledge to prevent patient harm. Verifying the client using two acceptable identifiers (name and date of birth) ensures the medication is given to the correct person. Reinforcing teaching about dietary potassium is well within the PN scope and essential for clients taking a potassium-wasting loop diuretic like furosemide. Furthermore, recognizing a critically low potassium level as a direct contraindication for furosemide and escalating this finding to the RN demonstrates safe and required clinical judgment.

Adım Adım Çözüm

1
Evaluate each action against the practical nurse (PN) scope of practice and medication safety principles.
Identify actions that are safe, legal, and appropriate for a PN to perform independently.
The NCLEX-PN requires an understanding of proper delegation, scope of practice boundaries, and adherence to the rights of medication administration.
2
Analyze the action of verifying identity using two identifiers (name and date of birth).
This is a correct action.
It fulfills the 'right client' medication right, which is a critical, non-negotiable safety standard.
3
Analyze the action of administering IV push morphine.
This is an incorrect action.
Administering IV push medications generally exceeds the PN scope of practice and must be performed by an RN.
4
Analyze the action of accepting verbal math calculations without independent verification.
This is an incorrect action.
Nurses must independently calculate and verify all medication dosages prior to administration to intercept potential math errors.
5
Analyze the action of reinforcing teaching about potassium-rich foods.
This is a correct action.
Reinforcing initial teaching provided by an RN is within the PN scope of practice, and furosemide is a potassium-wasting diuretic.
6
Analyze the action of using a room number for identification.
This is an incorrect action.
A room number is strictly prohibited as a patient identifier due to the high risk of error if a client is moved.
7
Analyze the action of withholding furosemide for a critically low potassium level and reporting to the RN.
This is a correct action.
Furosemide depletes potassium; giving it to a client with hypokalemia is highly dangerous. PNs must recognize critical labs, withhold contraindicated medications, and notify the RN immediately.
