Cevabı ve açıklamayı göster

Cevap: Assist the client into a prone position for 30 minutes three times a day.; Ensure the client's left knee remains fully extended while resting in bed.; Instruct the client to perform active range-of-motion exercises with the right leg.

Cevap

The nurse should assist the client into a prone position periodically, ensure the left knee remains extended, and instruct the client to perform active range-of-motion exercises on the unoperated leg.
The correct interventions focus on preventing flexion contractures and maintaining strength. Prone positioning stretches the hip flexors, keeping the knee extended prevents hamstring shortening, and exercising the unaffected limb preserves mobility for future rehabilitation.

Adım Adım Çözüm

1
Analyze the client's post-operative timeframe.
The client is 48 hours post-operation for a below-the-knee amputation.
Timing dictates appropriate positioning; elevation is only acceptable in the first 24 hours.
2
Identify the primary musculoskeletal risks for this specific procedure.
A below-the-knee amputation carries a high risk for both hip and knee flexion contractures.
Preventing contractures is essential for future prosthesis fitting and ambulation.
3
Evaluate each intervention against the goal of preventing hip and knee flexion.
Prone positioning and knee extension prevent contractures, while pillows, knee gatches, and prolonged sitting promote them.
Selecting the correct evidence-based basic care measures ensures safe recovery.

The client's vital signs are: blood pressure 102/64 mm Hg102/64\text{ mm Hg} (baseline 138/82 mm Hg138/82\text{ mm Hg}), heart rate 114 beats/min114\text{ beats/min}, and respiratory rate 28 breaths/min28\text{ breaths/min}. The nurse notes asymmetrical chest wall expansion and a subtle deviation of the trachea to the right. Which action should the practical nurse take first?

Cevabı ve açıklamayı göster

Cevap: Apply supplemental oxygen and urgently notify the supervising registered nurse or rapid response team.

Cevap

The practical nurse should immediately apply supplemental oxygen and escalate the situation by notifying the supervising registered nurse or rapid response team.
The client is exhibiting classic signs of a tension pneumothorax, a severe and life-threatening complication of a thoracentesis. The accumulation of air in the pleural space causes mediastinal shift (evidenced by tracheal deviation) and hemodynamic collapse (evidenced by dropping blood pressure and rising heart rate). As this is a medical emergency requiring advanced intervention (such as needle decompression), the practical nurse's most critical role is to support oxygenation and immediately escalate to the RN or rapid response team.

Adım Adım Çözüm

1
Analyze the assessment findings in the context of the recent procedure.
The client has restlessness, tachypnea, tachycardia, hypotension, asymmetrical chest expansion, and tracheal deviation following a thoracentesis.
Recognizing early and late signs of procedural complications is a critical component of risk reduction.
2
Identify the underlying complication indicated by the clinical data.
The specific combination of tracheal deviation, asymmetrical chest movement, and hemodynamic instability strongly indicates a developing tension pneumothorax.
A tension pneumothorax is a known, life-threatening complication of pleural space access that traps air in the chest, compressing the heart and contralateral lung.
3
Determine the priority, scope-appropriate nursing action.
The nurse must initiate basic supportive care (oxygen therapy) and immediately notify higher-level providers (RN/Rapid Response).
Treating a tension pneumothorax requires advanced interventions (needle decompression, chest tube) which fall outside the LPN scope, making immediate escalation the priority.

Cevap: A morning serum potassium level of 2.8 mEq/L

Cevap

A morning serum potassium level of 2.8 mEq/L
The correct answer is the serum potassium level of 2.8 mEq/L. Gastric secretions are rich in electrolytes, particularly potassium. The removal of 1,800 mL of gastric fluid significantly increases the risk for severe hypokalemia (normal range is 3.5 to 5.0 mEq/L). A level of 2.8 mEq/L is a critical value that can lead to fatal cardiac dysrhythmias, directly threatening circulation. This requires immediate escalation to the registered nurse for urgent intravenous replacement therapy.

Adım Adım Çözüm

1
Analyze the intervention and its physiological effects.
The client has an NG tube to suction that has removed a large volume (1,800 mL) of gastric fluid.
Gastric fluid contains high concentrations of electrolytes, primarily potassium, chloride, and hydrogen ions.
2
Evaluate the risk potential based on the fluid loss.
The massive removal of gastric contents places the client at severe risk for metabolic alkalosis and hypokalemia.
Depletion of these specific electrolytes must be anticipated when reviewing laboratory data and assessing the client.
3
Prioritize the assessment findings to identify the most life-threatening complication.
A potassium level of 2.8 mEq/L is critically low and poses an immediate threat of fatal cardiac dysrhythmias.
While elevated BUN and borderline vital signs indicate dehydration, they are expected secondary issues. The critical electrolyte imbalance directly threatens circulation and requires urgent RN escalation.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to identify the client, cleanse the finger, let it air dry, puncture the skin and wipe the first drop, then test the second drop.
Performing the steps in this specific order guarantees both client safety and the exact accuracy of the diagnostic lab value. Identifying the client is always the priority. Cleansing the site removes surface bacteria and residual sugars. Allowing the alcohol to naturally air dry ensures it does not alter the glucose result or cause a burning sensation upon puncture. Wiping away the first drop of blood is crucial because it contains serous tissue fluid that dilutes the sample. The second drop provides an accurate capillary specimen, which is vital for safe medication administration.

Adım Adım Çözüm

1
Verify identity and explain the procedure.
The correct client is confirmed and prepared.
Prevents medication and diagnostic errors by ensuring the right patient is being tested.
2
Cleanse the lateral aspect of the finger.
The puncture site is sanitized.
Reduces the risk of infection and removes any external glucose (e.g., from food) on the skin.
3
Allow the alcohol to air dry.
The site is dry and ready for puncture.
Wet alcohol can cause stinging during puncture and can hemolyze the red blood cells, leading to an inaccurate reading.
4
Puncture the skin and wipe away the first drop of blood.
Tissue fluid is removed from the sample site.
The initial drop of blood is heavily mixed with interstitial serous fluid, which can artificially dilute the blood glucose concentration.
5
Apply the second drop of blood to the test strip.
An accurate glucose reading is obtained.
The second drop consists of pure capillary blood, providing the most reliable value for potential insulin administration.

A client is recovering on the surgical unit following an abdominal procedure and receives a prescribed dose of intravenous morphine for severe pain. Shortly after, the practical nurse (PN) finds the client minimally responsive with a respiratory rate of 7 breaths/min. The PN immediately summons the registered nurse (RN), who administers intravenous naloxone. Fifteen minutes later, the client is fully awake and breathing at 16 breaths/min. Which action should the PN prioritize next?

Cevabı ve açıklamayı göster

Cevap: Monitor the client's respiratory rate and level of consciousness closely over the next several hours.

Cevap

Monitor the client's respiratory rate and level of consciousness closely over the next several hours.
Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression. However, its duration of action is significantly shorter (approximately 30 to 81 minutes) than that of morphine. As the naloxone is metabolized and cleared from the body, the residual morphine can cause a re-emergence of respiratory depression. Therefore, the most critical action is to closely monitor the client's respiratory rate, oxygenation, and level of consciousness for several hours to quickly identify and manage any recurring depression.

Adım Adım Çözüm

1
Analyze the pharmacological properties of the administered medications.
Naloxone is an opioid antagonist that reverses the effects of morphine, but it has a significantly shorter half-life (30 to 81 minutes) compared to most opioids.
Understanding drug pharmacokinetics is essential to anticipate the client's physiological response over time.
2
Identify the primary clinical risk for the client.
The client is at high risk for recurring respiratory depression as the naloxone wears off before the morphine is fully metabolized.
Patient safety requires anticipating and preventing life-threatening complications.
3
Determine the priority action within the PN's legal scope of practice.
Continuous and close monitoring of the client's respiratory status and level of consciousness is the most critical and appropriate intervention.
This ensures immediate detection of recurring respiratory depression while remaining within the boundaries of practical nursing practice.

A practical nurse (PN) is caring for a client with a history of heart failure who is receiving a continuous intravenous (IV) infusion of 0.9% sodium chloride at 150 mL/hr for mild dehydration. During data collection, the PN notes the client's heart rate has increased from 80 to 118 bpm, and blood pressure has risen from 110/70 to 160/90 mmHg. The client becomes newly restless and states, "My chest feels tight and I cannot catch my breath." Which action should the PN take first?

Cevabı ve açıklamayı göster

Cevap: Elevate the head of the bed and decrease the IV infusion rate.

Cevap

The correct action is to elevate the head of the bed and decrease the IV infusion rate.
The correct answer directly addresses the client's symptoms of fluid volume overload and impending pulmonary edema. Elevating the head of the bed uses gravity to facilitate lung expansion and improve oxygenation (Breathing priority), while decreasing the IV fluid rate prevents further fluid accumulation in the vascular space (Circulation priority). This is the safest and most immediate prioritization of care before notifying the RN.

Adım Adım Çözüm

1
Analyze the clinical cues provided in the scenario.
The client has a rapid heart rate, elevated blood pressure, new-onset restlessness, and shortness of breath while receiving a high-volume IV fluid infusion.
Identifying these cues is necessary to recognize the development of fluid volume overload and impending pulmonary edema, especially in a client with a history of heart failure.
2
Prioritize interventions based on the ABCs (Airway, Breathing, Circulation).
The immediate need is to support the client's breathing and halt the circulatory fluid overload.
Respiratory distress is a life-threatening complication that takes absolute priority over routine monitoring, symptom documentation, or psychosocial reassurance.
3
Determine the appropriate action within the PN scope of practice.
The PN must immediately position the client upright to ease breathing, slow the IV to a keep-vein-open rate to prevent further fluid accumulation, and then escalate the situation to the RN.
These physical interventions quickly and safely stabilize the client's airway and circulation while awaiting further medical orders.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for administering a Z-track IM injection is: pull the skin laterally, insert the needle at 90 degrees, inject the medication slowly, wait 10 seconds, and finally withdraw the needle before releasing the skin.
The Z-track method is designed to prevent irritating or staining medications (such as iron dextran) from leaking into the subcutaneous tissue. The correct sequence ensures the skin is displaced prior to needle insertion and remains displaced until after the needle is fully withdrawn. This creates a zig-zag path that permanently seals the medication within the muscle.

Adım Adım Çözüm

1
Pull the overlying skin and subcutaneous tissue laterally 1 to 1.5 inches.
The tissue is displaced from its normal alignment.
Displacing the tissue creates a staggered pathway that prevents medication leakage into the subcutaneous tissue.
2
Insert the needle at a 90-degree angle using a smooth, dart-like motion.
The needle enters the deep muscle.
A 90-degree angle ensures the medication reaches the vascular muscle layer rather than the subcutaneous fat.
3
Inject the medication slowly and steadily over several seconds.
The medication is delivered into the muscle.
Slow injection allows the medication to disperse evenly and minimizes tissue irritation.
4
Wait for 10 seconds while leaving the needle in place.
The medication begins to absorb.
Pausing prevents the medication from tracking back up the needle pathway immediately upon withdrawal.
5
Withdraw the needle smoothly and immediately release the retracted skin.
The needle track is sealed.
Releasing the skin after withdrawal restores the tissue alignment, sealing the track and locking the medication safely in the muscle.

Cevap

The correct sequence is to first position and lock the wheelchair on the strong side, sit the client on the edge of the bed with proper footwear, apply a transfer belt, brace the weak leg, and finally instruct the client to stand, pivot, and reach for the armrests.
Safe transfer of a client with one-sided weakness (hemiparesis) requires prioritizing the use of the unaffected side and maintaining strict fall precautions. The environment must first be prepared by placing the locked wheelchair on the strong side. The client is then safely positioned at the edge of the bed with non-skid footwear. A transfer belt is applied for grip, and the nurse must brace the weak leg to prevent buckling before initiating the stand-and-pivot motion.

Adım Adım Çözüm

1
Place the wheelchair parallel to the bed on the client's strong side and lock the wheels.
The environment is secured for a safe transfer.
Transferring toward the strong side allows the client to use their unaffected limbs to support their body weight.
2
Assist the client to sit on the edge of the bed and ensure they are wearing non-skid footwear.
The client is positioned upright and feet are protected from slipping.
Sitting allows time to assess for dizziness (orthostatic hypotension), and proper footwear prevents falls on smooth floors.
3
Secure a transfer belt around the client's waist over their clothing.
The transfer belt is securely fastened.
The belt provides the nurse with a firm, safe grip to assist with weight-bearing without pulling on the client's arms.
4
Face the client, maintain a wide base of support, and brace the client's left knee and foot.
The client's weak side is physically supported by the nurse.
Hemiparesis causes muscle weakness; bracing prevents the affected leg from buckling under the client's weight.
5
Instruct the client to stand, pivot on the right leg, and reach back for the wheelchair armrests.
The client is safely seated in the wheelchair.
Pivoting on the strong leg maximizes client independence and safety while completing the transfer.

An 82-year-old client is admitted to the medical-surgical unit with a severe systemic infection and is prescribed scheduled doses of intravenous (IV) piggyback gentamicin and oral levofloxacin. During the morning assessment, the practical nurse (PN) observes that the client, who was alert and oriented the previous evening, is now highly agitated and disoriented to time and place. The client's morning laboratory results reveal a serum creatinine of 2.8 mg/dL (baseline was 0.9 mg/dL on admission). Which action should the PN take first regarding the client's care and scheduled medications?

Cevabı ve açıklamayı göster

Cevap: Withhold both the gentamicin and levofloxacin, and immediately notify the supervising registered nurse (RN) of the acute neurological changes and elevated creatinine level.

Cevap

The correct action is to withhold both the gentamicin and levofloxacin, and immediately alert the RN to the client's acute confusion and critical laboratory values.
The correct action demonstrates an understanding of pharmacology, gerontology, and safe scope of practice. The client is exhibiting signs of acute kidney injury, evidenced by a significantly elevated serum creatinine level. Gentamicin is highly nephrotoxic, and levofloxacin requires adequate renal clearance. Administering these medications during an acute kidney injury can lead to severe systemic toxicity. Furthermore, the sudden onset of confusion and agitation in an older adult indicates acute delirium, likely secondary to the infection or impending toxicity, which is a medical emergency. The practical nurse must advocate for client safety by withholding the potentially harmful medications and urgently escalating these critical findings to the registered nurse for provider intervention.

Adım Adım Çözüm

1
Analyze the client's morning laboratory results in the context of their prescribed medications.
The serum creatinine has increased from a baseline of 0.9 mg/dL to 2.8 mg/dL, indicating acute kidney injury (AKI). Gentamicin is a highly nephrotoxic aminoglycoside, and levofloxacin is renally cleared.
Administering nephrotoxic or renally cleared medications during an acute kidney injury can lead to severe, irreversible systemic toxicity.
2
Evaluate the client's sudden change in neurological status.
The client exhibits new-onset agitation and disorientation to time and place.
Acute, sudden confusion in an older adult is a hallmark sign of delirium, which is a medical emergency often triggered by infection, medication toxicity, or acute metabolic disturbances (such as AKI).

During a morning assessment, a client receiving continuous total parenteral nutrition (TPN) appears diaphoretic and exhibits sudden confusion. The client's capillary blood glucose level is 4242 mg/dL. The client's medication administration record includes a PRN prescription for 5050 mL of 50%50\% dextrose in water (D50W) intravenous (IV) push for severe hypoglycemia. Based on the practical nurse scope of practice, which action is most appropriate?

Cevabı ve açıklamayı göster

Cevap: Promptly notify the registered nurse to administer the prescribed intravenous push medication

Cevap

The practical nurse should promptly notify the registered nurse to administer the prescribed intravenous push medication.
The client is experiencing a hypoglycemic emergency requiring immediate pharmacological intervention. Because the client has an altered mental status, oral intake is unsafe due to aspiration risks. The prescribed medication is an intravenous push, which is outside the scope of practice for a practical nurse. Therefore, the correct and safest action is to immediately notify the registered nurse, who can legally administer the IV push medication.

Adım Adım Çözüm

1
Analyze the client's clinical presentation and blood glucose results.
The client has symptomatic hypoglycemia, indicated by diaphoresis and confusion, with a critical blood glucose of 4242 mg/dL.
Identifying the clinical emergency is the first step in prioritizing care.
2
Evaluate the safety of oral versus parenteral interventions.
Oral carbohydrates are contraindicated because the client's sudden confusion creates a high risk for aspiration.
Airway protection must be prioritized in clients with altered mental status.
3
Determine the appropriate administration of the prescribed pharmacological therapy within the practical nurse scope of practice.
The prescribed treatment is IV push D50W, which requires a registered nurse's scope of practice to administer safely.
Practical nurses must not accept tasks or administer medications that exceed their legal scope of practice, such as IV push medications.
4
Select the action that ensures safe, immediate client care.
Escalating the situation to the registered nurse immediately ensures the client receives the necessary emergency medication.
Immediate collaboration with the registered nurse is required for critical interventions that fall outside the practical nurse's scope.

Cevap

To properly execute a 24-hour urine collection, the nurse must first instruct the client to empty the bladder and discard that urine, document the start time immediately, collect all subsequent urine in a chilled container, obtain one final void exactly 24 hours later, and then promptly label and send the completed specimen to the laboratory.
A 24-hour urine collection requires precise timing and sequencing to accurately measure kidney function. The protocol must always begin with an empty bladder (by discarding the first void) so only newly produced urine is measured. The start time must be documented immediately. All subsequent urine is kept cold to preserve its chemical composition. Exactly 24 hours later, the client voids one last time to finalize the collection, after which the complete specimen is labeled and sent for analysis.

Adım Adım Çözüm

1
Have the client void and discard the urine.
The bladder is emptied of preexisting urine.
Ensures the 24-hour period starts with no older urine in the bladder, which would skew the volume and analyte calculations.
2
Record the time of the discarded void.
The exact start time is established.
Provides a definitive, documented timestamp to calculate the 24-hour completion mark accurately.
3
Collect all subsequent urine and store it on ice or in a refrigerator.
All urine produced during the testing window is safely stored.
Cold storage preserves the specimen's integrity and prevents the breakdown of substances being measured.
4
Instruct the client to void exactly 24 hours after the start time and add this to the collection.
The final amount of urine produced in the period is captured.
Completes the physiological 24-hour cycle of urine production.
5
Label and transport the container.
The specimen reaches the lab safely and promptly.
Maintains specimen viability and ensures accurate patient identification for diagnostics.

Cevap

The correct sequence is to first instruct the client to exhale and bear down, cover the site with petroleum gauze, secure the tape on three sides, assess the respiratory status, and finally notify the healthcare team.
In any respiratory emergency where the pleural space is exposed to the atmosphere, the absolute first priority is to stop air entry (Airway/Breathing principle). Asking the client to exhale and bear down provides an immediate internal pressure block, allowing the nurse a few seconds to apply the physical petroleum gauze seal. Taping it on three sides is the standard of care to create a one-way flutter valve. Only after securing the airway and breathing mechanics should the nurse assess the physiological response and notify the team.

Adım Adım Çözüm

1
Instruct the client to forcefully exhale and bear down.
Intrathoracic pressure immediately increases.
This prevents atmospheric air from entering the pleural cavity through the newly opened wound, which would collapse the lung.
2
Cover the insertion site with a sterile petroleum gauze.
An airtight seal is created over the wound.
The petroleum gauze acts as an immediate physical barrier to stop further air exchange between the atmosphere and the pleural space.
3
Secure the occlusive dressing with tape on three sides.
A flutter valve (one-way valve) is established.
Taping only three sides allows any trapped air to escape during exhalation but prevents outside air from being drawn in during inhalation, drastically reducing the risk of a tension pneumothorax.
4
Assess the client's respiratory rate and oxygen saturation.
Baseline respiratory data is obtained.
The nurse must evaluate if the client is experiencing respiratory distress, hypoxia, or signs of a developing pneumothorax after the acute intervention is applied.
5
Notify the registered nurse and healthcare provider.
The medical team is alerted to the critical event.
The client will likely require emergency medical intervention, such as a chest X-ray and the insertion of a new chest tube.

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with proper positioning, followed by tube preparation, safe insertion, fluid instillation, and finally, managing potential complications like cramping.
Administering an enema requires sequential steps that prioritize safety, anatomical alignment, and client comfort. Proper left-sided positioning must occur first so gravity can assist fluid travel into the descending colon. Lubrication must happen before insertion to prevent mucosal damage. The tube is then inserted following the natural curve of the bowel (toward the umbilicus). Only after proper insertion should the clamp be opened to begin instillation. Finally, if the client experiences cramping during the procedure, the nurse must intervene by lowering the bag to reduce flow pressure.

Adım Adım Çözüm

1
Assist the client into the left lateral Sims' position.
The client's descending colon is positioned optimally.
Gravity aids the flow of solution into the sigmoid and descending colon when the client is on their left side.
2
Lubricate the distal end of the enema tubing.
The tube tip becomes slick and smooth.
Lubrication prevents friction, discomfort, and trauma to the rectal mucosa.
3
Insert the tubing gently into the rectum angled toward the umbilicus.
The tube safely enters the lower bowel.
Angling toward the umbilicus aligns the tube with the anatomical contour of the rectum, minimizing the risk of bowel perforation.
4
Unclamp the tubing and allow the fluid to instill slowly.
The enema solution begins to flow into the client.
Slow instillation minimizes sudden bowel distention, which can cause intense cramping.
5
Lower the enema container if the client reports abdominal cramping.
The flow rate of the solution decreases.
Lowering the bag reduces hydrostatic pressure, alleviating cramps without having to remove the tube entirely.

A practical nurse is preparing to administer prescribed oral acetaminophen to a pediatric client experiencing a fever. The healthcare provider has prescribed 240240 mg to be given every 66 hours as needed. The medication is available in a liquid concentration of 160160 mg/55 mL. Which action describes the safest and most appropriate procedure for the practical nurse to follow?

Cevabı ve açıklamayı göster

Cevap: Calculate the required dose as 7.57.5 mL, verify the client's identity using two distinct identifiers, and administer the medication.

Cevap

Calculate the required dose as 7.57.5 mL, verify the client's identity using two distinct identifiers, and administer the medication.
The practical nurse correctly calculates the dose using the standard formula: 240 mg160 mg×5 mL=7.5 mL\frac{240 \text{ mg}}{160 \text{ mg}} \times 5 \text{ mL} = 7.5 \text{ mL}. Furthermore, the nurse safely adheres to strict medication administration protocols by using two distinct client identifiers prior to administering the drug.

Adım Adım Çözüm

1
Calculate the correct medication dosage using the formula: DesiredHave×Volume\frac{\text{Desired}}{\text{Have}} \times \text{Volume}.
240 mg160 mg×5 mL=1.5×5 mL=7.5 mL\frac{240 \text{ mg}}{160 \text{ mg}} \times 5 \text{ mL} = 1.5 \times 5 \text{ mL} = 7.5 \text{ mL}.
Accurate calculation is the first step in ensuring the client receives the safe and therapeutic dose prescribed.
2
Identify the safety requirements for medication administration.
The nurse must use at least two distinct client identifiers (e.g., name and date of birth confirmed with an identification band) and must administer the medication personally.
Adhering to the 'rights of medication administration' prevents medication errors, and medication administration cannot be delegated to a UAP.
3
Select the option that combines the correct calculation with safe, within-scope nursing practice.
The option calculating 7.57.5 mL and verifying using two identifiers is the only comprehensively safe and correct choice.
It fulfills all pharmacological and patient safety standards within the practical nurse's scope.
