Cevap

The correct sequence is: shake and attach the inhaler, instruct the client to exhale completely, seal the lips tightly around the spacer mouthpiece, depress the canister to release medication, have the client inhale slowly and hold their breath, and finally, rinse the mouth and spit.
Administering a corticosteroid via an MDI with a spacer requires a precise sequence to ensure maximum medication delivery to the lungs and to minimize local adverse effects. The sequence begins with device preparation (shaking and attaching). Next, the client must be prepared by exhaling completely to allow for a maximal inspiratory volume. Once the lungs are emptied, a tight seal is made around the mouthpiece to prevent leakage. Only then is the canister depressed to suspend the medication in the spacer. The client then inhales slowly and holds their breath for 10 seconds, allowing the particles to settle deeply in the bronchioles. Because fluticasone is a corticosteroid, the final and mandatory step is rinsing the mouth and spitting to prevent oral candidiasis.

Adım Adım Çözüm

1
Shake the metered-dose inhaler vigorously and insert it into the end of the spacer.
The medication is uniformly mixed and the device is assembled.
Inhaled suspensions can separate; shaking ensures the client receives an accurate, measured dose.
2
Instruct the client to exhale completely to empty the lungs.
The client's lungs are emptied of residual volume.
Starting with empty lungs maximizes the volume of the subsequent inhalation, drawing the medication deeper into the respiratory tract.
3
Place the spacer mouthpiece into the client's mouth and ensure the lips are sealed tightly around it.
A closed system is created between the spacer and the client's airway.
A tight seal prevents the aerosolized medication from escaping out of the mouth during release.
4
Depress the inhaler canister once to release the medication into the spacer chamber.
One dose of medication is suspended inside the spacer.
The spacer holds the medication in a fine cloud, removing the need for the client to perfectly coordinate pressing the canister with inhaling.
5
Instruct the client to inhale slowly and deeply, then hold their breath for 10 seconds.
The medication travels to the lower airways and settles.
Slow inhalation prevents turbulent airflow from depositing medication in the back of the throat. Holding the breath maximizes absorption in the lungs.
6
Assist the client to rinse their mouth with water and spit it out.
Residual medication is cleared from the oropharynx.
Fluticasone is an inhaled corticosteroid. Leaving residue in the mouth increases the risk of oral fungal infections (candidiasis) and systemic absorption.

A practical nurse (PN) is reviewing the medication administration record for a client who is prescribed oral cephalexin for a wound infection. The client's medical history indicates a severe anaphylactic allergy to penicillin. Which of the following actions should the PN take?

Cevabı ve açıklamayı göster

Cevap: Withhold the cephalexin and promptly notify the registered nurse (RN) or healthcare provider.

Cevap

The correct action is to withhold the medication and notify the RN or healthcare provider because cephalosporins, such as cephalexin, have a known risk of cross-sensitivity in clients with severe penicillin allergies.
The correct response prioritizes client safety by preventing a potential life-threatening allergic reaction. Cephalosporins (like cephalexin) and penicillins share a beta-lactam ring structure, meaning clients with a severe penicillin allergy have a significant risk of cross-anaphylaxis. The practical nurse must recognize this contraindication, withhold the scheduled dose, and communicate the finding to the supervising nurse or provider for a potential prescription change.

Adım Adım Çözüm

1
Review the prescribed medication and the client's medical history.
The client is prescribed cephalexin and has a known anaphylactic allergy to penicillin.
Comparing new prescriptions against documented allergies is an essential safety check before any medication administration.
2
Analyze the pharmacological relationship between the prescribed drug and the allergen.
Cephalexin is a cephalosporin antibiotic, which shares a similar beta-lactam ring structure with penicillins.
Clients with severe penicillin allergies are at a significant risk for cross-sensitivity and may experience anaphylaxis if given a cephalosporin.
3
Determine the appropriate and safe nursing intervention within the practical nurse scope of practice.
The medication must be withheld and the finding escalated to the registered nurse or prescribing provider.
Withholding a contraindicated medication prevents patient harm, and notifying the provider allows for an alternative, safe antibiotic to be prescribed.

During the morning medication pass at a long-term care facility, a practical nurse reviews the electronic health record of a resident diagnosed with heart failure. The resident is scheduled to receive oral doses of digoxin and furosemide. Morning laboratory results indicate a serum potassium of 3.1 mEq/L (3.1 mmol/L) and a serum digoxin level of 1.3 ng/mL (1.66 nmol/L). The resident's current vital signs are blood pressure 102/58 mm Hg, heart rate 94 beats per minute, and respiratory rate 18 breaths per minute. Which action should the nurse prioritize to minimize the risk of complications?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled doses of both medications and immediately report the clinical findings to the supervising registered nurse.

Cevap

The practical nurse should prioritize withholding both the digoxin and furosemide and immediately escalating the abnormal laboratory and vital sign findings to the supervising registered nurse.
The correct answer involves withholding both medications and notifying the registered nurse. A serum potassium level of 3.1 mEq/L indicates hypokalemia (normal is 3.5-5.0 mEq/L). Hypokalemia significantly increases the myocardium's sensitivity to digoxin, placing the client at high risk for fatal dysrhythmias and toxicity, even when the serum digoxin level (1.3 ng/mL) is strictly within the normal therapeutic range (0.5-2.0 ng/mL). Furthermore, administering furosemide, a loop diuretic, would exacerbate the hypokalemia. The borderline vital signs (blood pressure 102/58 mm Hg, heart rate 94 bpm) may indicate early volume depletion or decreased cardiac output. The safest action within the practical nurse's scope is to withhold the medications and escalate the critical findings.

Adım Adım Çözüm

1
Analyze the morning laboratory results against normal reference ranges.
The potassium level of 3.1 mEq/L is critically low (hypokalemia). The digoxin level of 1.3 ng/mL is within the normal therapeutic range.
Identifying abnormal values is the critical first step in risk reduction.
2
Evaluate the pharmacological interactions between the prescribed medications and current laboratory values.
Furosemide causes potassium wasting, which will worsen the hypokalemia. Hypokalemia increases the risk of digoxin toxicity even at normal serum levels.
Understanding drug-lab interactions prevents the administration of potentially lethal medications.
3
Analyze the client's vital signs for early signs of decompensation.
The blood pressure of 102/58 mm Hg and heart rate of 94 beats per minute are borderline and may indicate volume depletion or early dysrhythmia.
Recognizing subtle physiological changes helps identify emerging complications.
4
Determine the appropriate nursing intervention within the practical nurse's scope of practice.
The nurse must withhold both medications to prevent patient harm and immediately notify the registered nurse.
Escalating critical findings ensures the client receives appropriate medical intervention and maintains patient safety.

While observing an adolescent client on the surgical unit who had a tonsillectomy earlier in the day, the practical nurse notes that the client is restless and swallowing repeatedly. The continuous monitor shows a current heart rate of 118118 beats per minute, compared to a baseline of 8282 beats per minute. Which action should the practical nurse take FIRST?

Cevabı ve açıklamayı göster

Cevap: Examine the back of the client's throat using a penlight to check for active bleeding.

Cevap

The priority action is to directly assess the surgical site for active bleeding.
Frequent swallowing, clearing of the throat, restlessness, and unexplained tachycardia (a heart rate of 118118 beats per minute) in a post-tonsillectomy client are classic early signs of hemorrhage. Because blood dripping down the back of the throat triggers the swallowing reflex, the priority action for the practical nurse is to directly assess the surgical site using a penlight. This immediate data collection is essential for determining the next steps to protect the airway and circulation before notifying the registered nurse.

A practical nurse is caring for a client who is receiving continuous enteral nutrition via a nasogastric tube. The client suddenly begins coughing vigorously, becomes tachypneic, and appears cyanotic. Arrange the following nursing actions in the correct priority order to reduce the client's risk for further complications. (Place the first action at the top and the last action at the bottom.)

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct priority sequence is to first stop the continuous enteral feeding, then turn the client to a lateral side-lying position, next auscultate lung sounds and measure oxygen saturation, and finally notify the supervising Registered Nurse (RN).
When a client exhibits sudden respiratory distress during an enteral feeding, active aspiration is highly suspected. The sequence of actions follows the principle of neutralizing the immediate threat first. The nurse must stop the pump to prevent further aspiration. Next, repositioning the client laterally protects the airway and facilitates drainage. Only after these immediate physical safeguards are in place should the nurse obtain focused assessment data (vital signs, lung sounds) to accurately report the client's condition to the supervising RN for further medical orders.

Adım Adım Çözüm

1
Recognize the signs of active aspiration (coughing, cyanosis) and immediately turn off the enteral feeding pump.
Halts the introduction of additional formula into the client's lungs.
Eliminating the cause of the immediate threat is always the highest priority in emergency risk reduction.
2
Reposition the client into a lateral (side-lying) position.
Uses gravity to help clear the airway.
Prevents further downward movement of aspirated fluid and promotes outward drainage of secretions.
3
Perform a focused respiratory assessment, including oxygen saturation and lung auscultation.
Provides objective baseline data regarding the extent of respiratory compromise.
Assessment data is necessary to determine the client's current status only after the immediate airway threat is neutralized.
4
Escalate the findings to the Registered Nurse (RN).
Initiates further medical management.
The practical nurse must report critical changes so the RN can implement advanced interventions, such as ordering a chest radiograph or prescribing oxygen therapy.

Anahtar Kavram

In emergency situations such as active aspiration, the practical nurse must prioritize immediate independent interventions that remove the risk (stopping feeding) and protect the airway (positioning) before collecting assessment data or notifying the healthcare team.

Cevap

1. Stop the blood transfusion immediately. 2. Initiate an infusion of 0.9% sodium chloride using new intravenous tubing. 3. Obtain a full set of vital signs and assess the client's respiratory status. 4. Notify the charge nurse and the prescribing healthcare provider. 5. Prepare to return the blood bag, tags, and administration set to the blood bank.
In the event of a suspected blood transfusion reaction, the absolute first priority is to stop the transfusion to prevent further administration of incompatible blood. The second step is to maintain a patent IV line for emergency medications and fluid resuscitation; this must be done with 0.9% sodium chloride and completely new tubing to avoid pushing remaining blood from the old tubing into the client. Once the source of harm is stopped and access is secured, the nurse must assess the client's vital signs and respiratory status to gather data. This clinical data is then immediately reported to the charge nurse and healthcare provider. Finally, as a follow-up administrative and diagnostic measure, the remaining blood, tags, and tubing are sent to the blood bank for investigation.

Adım Adım Çözüm

1
Recognize the signs of a severe adverse therapy response.
The client is experiencing a potential acute hemolytic transfusion reaction, indicated by lower back pain, chills, and dyspnea.
Early recognition dictates the immediate cessation of the offending agent.
2
Prioritize direct interventions based on removing the source of harm and supporting circulation.
Stopping the transfusion prevents further exposure. Starting normal saline with completely new tubing maintains hemodynamic stability without pushing more blood into the client.
Client safety is the highest priority; flushing the old tubing would actively harm the client.
3
Gather specific clinical data before escalating communication.
Vital signs and respiratory assessment provide a precise baseline of the client's compromised state.
The healthcare provider requires current, objective data to prescribe appropriate emergency pharmacological interventions.
4
Escalate the situation and perform required administrative follow-up.
The charge nurse and provider are notified, and the blood materials are prepared for the blood bank.
Interprofessional communication ensures timely medical intervention, and the blood bank must investigate the cause of the transfusion reaction.

In what order should the practical nurse perform the following actions? (Arrange from first to last)

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: Inspect the tubing, clamp the infusion, palpate the bladder, and then notify the registered nurse.
When a client on continuous bladder irrigation experiences sudden pain and a lack of output, an obstruction is highly likely. The nurse must first perform the quickest non-invasive check by inspecting the drainage tubing for kinks. If the tubing is clear, the blockage is internal (often a blood clot). The immediate safety priority is to clamp the flow of irrigation to prevent bladder rupture from continuous fluid input. After securing the client's safety, the nurse assesses the physical impact by palpating the bladder to gauge distention. Finally, the nurse reports these comprehensive findings to the registered nurse, who can initiate advanced interventions like manual irrigation to clear the clot.

Adım Adım Çözüm

1
Check the external equipment for simple mechanical issues.
Rules out kinks, clamped tubes, or dependent loops as the cause of the obstruction.
This is the fastest, least invasive assessment and can immediately resolve the issue if a kink is found.
2
Halt the continuous bladder irrigation flow.
Prevents any additional fluid from entering the obstructed bladder.
If fluid continues to enter a blocked bladder, it will cause severe pain and risks bladder trauma or rupture. Stopping the harm is the immediate priority.
3
Assess the client physically by palpating the suprapubic area.
Provides objective clinical data regarding the extent of urinary retention.
Physical assessment determines the severity of the client's physiological response to the obstruction.
4
Report the findings to the supervising registered nurse.
Initiates collaborative care for resolving internal obstructions.
Interventions like manual bladder irrigation to remove blood clots typically require RN execution or specific provider orders.

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with positioning the client, followed by lubricating the tube, inserting it to the correct depth, initiating the flow at the proper height, and finally monitoring for and managing any discomfort such as cramping.
The procedure follows a logical and safe progression: preparation of the client (positioning), equipment preparation (lubrication), safe execution (insertion and controlled fluid flow), and continuous evaluation (monitoring for and responding to cramps).

Adım Adım Çözüm

1
Position the client in the left lateral Sims' position.
The client's anatomy is optimally aligned to receive the fluid.
Gravity and the natural anatomical curve of the descending colon help retain the fluid and allow it to flow deeply into the bowel.
2
Lubricate the enema tip.
The tube surface is smoothed.
Lubrication prevents friction and mucosal tearing during insertion through the anal sphincters.
3
Insert the tube 3 to 4 inches into the rectum.
The tube safely passes the internal and external sphincters.
Ensures the fluid is delivered directly into the rectum and not expelled immediately.
4
Elevate the bag 12 to 18 inches and unclamp.
The solution begins to flow steadily into the bowel.
Provides adequate, safe hydrostatic pressure for fluid instillation without causing excessive force.
5
Monitor for cramping and lower or clamp the bag if it occurs.
The flow is adjusted based on client tolerance.
Rapid bowel distention causes severe pain; clamping or lowering the bag slows the instillation rate and relieves cramping.

Cevap: Raise the head of the bed to a high Fowler's position.; Obtain the client's blood pressure reading immediately.; Check the urinary catheter and drainage tubing for any obstructions.

Cevap

The correct immediate actions are to raise the head of the bed, obtain a blood pressure reading, and check the urinary catheter for obstructions.
The client is exhibiting classic signs of autonomic dysreflexia, a severe hypertensive crisis triggered by a noxious stimulus below the level of the spinal cord injury (T4). Elevating the head of the bed immediately helps lower blood pressure through orthostasis. Obtaining a blood pressure reading confirms the hypertensive crisis and establishes a baseline, while checking the urinary system addresses the most common cause of the syndrome (bladder distention from a kinked or blocked catheter).

Adım Adım Çözüm

1
Identify the clinical presentation.
The client's symptoms (pounding headache, profuse diaphoresis above the injury level, nasal congestion) in the context of a T4 spinal cord injury indicate autonomic dysreflexia.
Recognizing the syndrome is the critical first step in clinical judgment for a sudden client status change.
2
Prioritize immediate circulation and safety interventions.
Raising the head of the bed utilizes orthostatic pressure to help lower the blood pressure quickly.
This is a rapid, non-pharmacological way to mitigate the extreme hypertensive crisis.
3
Collect objective data and attempt to identify the trigger.
The nurse checks the blood pressure to confirm the severity of hypertension and inspects the urinary catheter.
Bladder distention is the most frequent noxious stimulus causing this reflex; removing the trigger is essential to resolving autonomic dysreflexia.

Cevap

The nurse should elevate the head of the bed to 30 to 45 degrees, support the head and neck with pillows to maintain neutral alignment, and apply an ice collar as prescribed.
Following neck surgery such as a partial thyroidectomy, basic care prioritizes protecting the airway and the surgical site. A semi-Fowler's position (head elevated 30 to 45 degrees) uses gravity to promote venous return and decrease edema, which protects the airway. Using pillows to support the head and maintain neutral alignment prevents hyperextension, reducing tension on the sutures. Finally, applying an ice collar is an effective comfort measure that induces vasoconstriction, limiting both swelling and bleeding.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: Elevate the head of the bed, verify tube placement, flush with sterile water, administer the medication, and flush again.
Administering medications via a nasogastric tube requires a strict sequence to prevent life-threatening complications such as aspiration pneumonia and to maintain tube integrity. The client must first be positioned safely (head elevated). Next, tube placement is verified to confirm gastric location. A pre-flush ensures patency and clears the line. The medication is then administered by gravity, followed immediately by a post-flush to deliver the full dose and prevent clogs.

Adım Adım Çözüm

1
Elevate the head of the bed to at least 30 to 45 degrees.
The client is placed in a semi-Fowler's position.
This utilizes gravity to reduce the risk of gastroesophageal reflux and aspiration into the lungs.
2
Verify correct tube placement by aspirating gastric contents and assessing pH.
Gastric placement is confirmed.
It is critical to ensure the tube has not become dislodged into the respiratory tract before instilling any fluids.
3
Flush the nasogastric tube with 15 to 30 mL of sterile water.
The tube is cleared of contents and patency is established.
Flushing prevents physical incompatibilities between gastric contents and the medication, while ensuring the tube is not blocked.
4
Instill the diluted medication into the syringe barrel, allowing it to flow by gravity.
The medication is delivered into the stomach.
Gravity instillation reduces the risk of applying too much pressure, which could damage the tube or the gastrointestinal mucosa.
5
Flush the nasogastric tube again with 15 to 30 mL of sterile water.
The tube is cleared of all medication residue.
This final flush ensures the client receives the entire medication dose and prevents the tube from becoming occluded by dried medication.

A practical nurse is caring for an older adult client with a history of atrial fibrillation who is prescribed daily warfarin. During morning rounds, the client appears suddenly confused and restless. The client's most recent International Normalized Ratio (INR) is 5.5. Which of the following actions should the nurse take first?

Cevabı ve açıklamayı göster

Cevap: Withhold the scheduled warfarin and immediately notify the registered nurse of the client's status.

Cevap

The nurse should withhold the scheduled warfarin and immediately notify the registered nurse of the client's status.
An INR of 5.5 is well above the typical therapeutic range of 2.0 to 3.0, indicating a severe risk for bleeding. Furthermore, the client's sudden confusion could be a symptom of an intracranial hemorrhage. The correct action within the practical nurse's scope of practice is to withhold the dose and urgently notify the registered nurse or healthcare provider to ensure patient safety.

Adım Adım Çözüm

1
Analyze the client's laboratory data.
The INR of 5.5 is significantly above the therapeutic range of 2.0 to 3.0 for atrial fibrillation.
Identifying abnormal laboratory values is essential to determine if a scheduled medication is safe to administer.
2
Evaluate the client's clinical presentation.
The client is an older adult exhibiting sudden confusion and restlessness.
Acute mental status changes can be a sign of poor perfusion or intracranial bleeding, especially in a client with a high bleeding risk.
3
Determine the appropriate nursing intervention within the practical nurse scope of practice.
The safest and most appropriate action is to withhold the medication and escalate the critical findings to the registered nurse.
The practical nurse cannot safely administer the medication or prescribe antidotes, making prompt reporting the priority.

Cevap: Assist with a partial bed bath while ensuring the posterior chest dressing remains dry and intact.; Provide a warmed blanket and dim the overhead room lights to promote relaxation.; Perform oral hygiene using moistened sponge swabs to alleviate mucous membrane dryness.

Cevap

The correct actions are to assist with a partial bed bath while protecting the dressing, provide a warmed blanket with dimmed lights, and perform oral hygiene using moistened swabs.
Providing a partial bed bath while keeping the dressing intact maintains hygiene without risking infection at the puncture site. Dimming lights and providing a warmed blanket are effective nonpharmacological comfort measures that promote rest. Using moistened swabs for oral care safely relieves the mucous membrane dryness often caused by continuous oxygen therapy.

Adım Adım Çözüm

1
Analyze the client's clinical status and recent procedure.
The client is weak, post-thoracentesis, on bed rest, and requires continuous oxygen therapy.
Understanding the clinical context is essential to determine safe basic care interventions.
2
Evaluate each care intervention for safety and appropriateness.
Bathing with dressing protection, environmental comfort measures, and oral care are safe and indicated.
These actions promote hygiene and comfort without compromising respiratory status or violating safety protocols.
3
Identify contraindicated actions that compromise safety.
Flat positioning, removing the oxygen cannula, and raising all four side rails are identified as unsafe.
These actions increase the risk of respiratory distress, hypoxia, and constitute unauthorized restraint use.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for mixing insulins is: clean both vials, inject air into the NPH vial, inject air into the Regular vial, draw up the Regular insulin, and finally draw up the NPH insulin.
When mixing short-acting (Regular) and intermediate-acting (NPH) insulin, the correct sequence ensures that the fast-acting insulin is not contaminated with the longer-acting insulin. The standard mnemonic is 'clear before cloudy.' After cleaning the vials, air is injected into the NPH vial first, followed by air into the Regular vial. The Regular (clear) insulin is drawn up first while the needle is already in the vial. Finally, the NPH (cloudy) insulin is drawn up to complete the exact total dose.

Adım Adım Çözüm

1
Clean the rubber stoppers of both insulin vials with alcohol swabs.
The stoppers are disinfected.
Maintains aseptic technique before inserting needles into the vials.
2
Inject an amount of air equal to the prescribed dose into the NPH insulin vial.
Pressure is equalized in the NPH vial.
Prevents a vacuum, making it easier to withdraw medication later. This is done first because the needle has not touched any insulin yet.
3
Inject an amount of air equal to the prescribed dose into the Regular insulin vial.
Pressure is equalized in the Regular vial.
Prepares the vial for immediate withdrawal of insulin.
4
Invert the Regular insulin vial and withdraw the prescribed dose into the syringe.
The short-acting insulin is drawn into the syringe.
Clear (Regular) insulin is drawn up first so that the vial is not contaminated with cloudy (NPH) insulin, which could alter the rapid action of future doses drawn from the Regular vial.
5
Insert the needle into the NPH insulin vial and withdraw the prescribed dose.
The total mixed dose is gathered in the syringe.
Cloudy (NPH) insulin is drawn up last. Care must be taken not to inject any Regular insulin into the NPH vial.

An older adult client in a long-term care facility is receiving a continuous enteral feeding via a nasogastric tube. The practical nurse is preparing to perform a complete bed bath and change the client's bed linens, which requires lowering the head of the bed. Which action is essential for the nurse to take?

Cevabı ve açıklamayı göster

Cevap: Stop the enteral feeding pump before lowering the head of the bed to a flat position.

Cevap

The nurse must stop the enteral feeding pump before lowering the head of the bed to a flat position.
Clients receiving continuous enteral feedings are at a high risk for aspiration if they are laid flat, as the formula can easily reflux from the stomach into the esophagus and airway. To safely perform a bed bath or linen change that requires a flat bed position, the practical nurse must first stop the feeding pump. The feeding should only be resumed once the procedure is finished and the head of the bed is returned to an elevation of at least 30 to 45 degrees.

Adım Adım Çözüm

1
Identify the client's current treatment and the physical requirements of the planned basic care procedure.
The client is receiving a continuous enteral feeding, and a complete bed bath requires the bed to be temporarily lowered to a flat position.
Understanding the intersection of prescribed therapies and basic care activities is necessary to identify potential safety hazards.
2
Recognize the primary safety risk associated with enteral feedings and patient positioning.
Administering enteral feedings while the client is supine creates a high risk for regurgitation and pulmonary aspiration.
Gravity is required to help keep the nutritional formula in the stomach and prevent reflux into the esophagus and airway.
3
Determine the necessary nursing intervention to mitigate this risk during the procedure.
The continuous feeding must be temporarily paused before the head of the bed is lowered.
Stopping the introduction of new formula into the stomach before laying the client flat prioritizes airway protection and physiological safety.
