During morning medication rounds, a practical nurse (PN) assesses a client with heart failure prior to administering a scheduled dose of oral digoxin. The client's current apical pulse is $56 \text{ beats/min}$ , and the most recent laboratory report reveals a serum potassium level of $3.1 \text{ mEq/L}$ . Based on these findings, which action should the PN take?

Administer half of the prescribed medication dose to prevent further lowering of the client's heart rate.

Administer the medication as prescribed and ensure the client receives a potassium-rich snack with breakfast.

Reassess the client's apical pulse in one hour and administer the scheduled dose if the heart rate is greater than

60 \text{ beats/min}

Withhold the digoxin dose and promptly report the clinical findings to the supervising registered nurse.

Cevabı ve açıklamayı göster

Cevap: Withhold the digoxin dose and promptly report the clinical findings to the supervising registered nurse.

Cevap

The practical nurse should withhold the digoxin dose and promptly report the clinical findings to the supervising registered nurse.

The correct action is to withhold the medication and report to the registered nurse. Digoxin is a cardiac glycoside that slows the heart rate, and it must be withheld if an adult client's apical pulse is less than

60 \text{ beats/min}

. Additionally, a serum potassium level of

3.1 \text{ mEq/L}

indicates hypokalemia (normal range is

3.5

5.0 \text{ mEq/L}

). Hypokalemia significantly increases the client's risk for developing dangerous digoxin toxicity, making it a critical finding that warrants withholding the drug and immediately notifying the supervising nurse.

Adım Adım Çözüm

Evaluate the client's apical pulse against standard administration parameters for digoxin.

The apical pulse is

56 \text{ beats/min}

, which is below the standard threshold of

60 \text{ beats/min}

for adults.

Digoxin slows the heart rate. Administering it to a bradycardic client can cause severe dysrhythmias.

Analyze the client's laboratory values in relation to the prescribed medication.

The serum potassium is

3.1 \text{ mEq/L}

, indicating hypokalemia (normal is

3.5

5.0 \text{ mEq/L}

Hypokalemia increases the sensitivity of the cardiac muscle to digoxin, significantly raising the risk of digoxin toxicity even at normal blood levels of the drug.

Determine the safest clinical action within the PN scope of practice.

The medication must be withheld due to both the low heart rate and the critical lab value, and the findings must be reported.

The PN must ensure client safety by withholding contraindicated medications and communicating abnormal assessment data to the RN or provider for further orders.

A practical nurse (PN) and a registered nurse (RN) are co-assigned to care for a client with acute heart failure. The primary healthcare provider prescribes furosemide $40\text{ mg}$ intravenous (IV) push stat. The RN prepares the medication in a syringe, hands it to the PN, and says, "The client's potassium is $3.8\text{ mEq/L}$ . Can you push this while I admit a new client?" What is the most appropriate action by the PN?

Decline the delegated task, as a serum potassium level of

3.8\text{ mEq/L}

is critically low and requires withholding the furosemide.

Accept the delegated task, provided the PN can independently verify the medication vial and client identifiers prior to administration.

Decline the delegated task, as administering medications via the IV push route is outside the standard scope of practice for a PN.

Cevap: Decline the delegated task, as administering medications via the IV push route is outside the standard scope of practice for a PN.

Cevap

The correct action is to decline the delegated task because administering medications via the IV push route is outside the standard scope of practice for a practical nurse.

The standard scope of practice for a practical nurse (PN) does not include the administration of intravenous (IV) push medications. This specific task requires the advanced assessment skills, pharmacological knowledge, and clinical judgment of a registered nurse (RN) to evaluate for immediate therapeutic or adverse reactions during the rapid administration into the bloodstream. Additionally, fundamental medication safety principles dictate that a nurse must never administer a medication drawn up by another individual, as doing so bypasses essential independent verification steps.

Adım Adım Çözüm

Analyze the requested route of medication administration.

The prescription is for an intravenous (IV) push medication.

The route of administration determines whether the task falls within the practical nurse's legal scope of practice.

Evaluate the client's laboratory data.

The client's serum potassium level is

3.8\text{ mEq/L}

, which is within the normal reference range of

3.5

5.0\text{ mEq/L}

Loop diuretics like furosemide can cause hypokalemia, making it essential to verify baseline potassium before administration.

Apply the legal scope of practice and medication administration safety standards.

The PN must decline the task because IV push medications are outside the standard scope of practice, and it is unsafe to administer a medication drawn up by another nurse.

Nurses are accountable for working within their authorized scope and adhering to the rights of medication administration to ensure client safety.

Cevabı ve açıklamayı göster

Cevap: Position the client upright in a high-Fowler's position.; Obtain a current pulse oximetry reading and assess lung sounds.; Pause the intravenous fluid infusion and urgently alert the supervising registered nurse.

Cevap

The correct actions are positioning the client upright in a high-Fowler's position, obtaining a pulse oximetry reading with lung sounds, and pausing the intravenous fluid infusion while alerting the registered nurse.

The client is presenting with classic manifestations of fluid volume overload complicated by pulmonary edema, which impairs gas exchange and leads to hypoxia (evidenced by the new-onset confusion). The immediate nursing priorities are to support the client's breathing by sitting them upright, to gather objective respiratory data to pass on to the medical team, and to halt the IV fluid infusion that is actively worsening the fluid overload. Rapid escalation to the RN is required because the client is unstable and requires advanced care.

Adım Adım Çözüm

Analyze the clinical cues in the scenario.

The combination of a moist cough, increased work of breathing, and new-onset confusion during IV fluid therapy strongly points to fluid volume overload leading to pulmonary edema and hypoxia.

Recognizing patterns of physiological decline is the first step in prioritizing clinical judgment.

Prioritize actions based on the ABCs (Airway, Breathing, Circulation).

Positioning the client upright is the fastest independent intervention the PN can perform to optimize breathing and lung expansion.

Mechanical positioning immediately reduces the work of breathing without requiring an order.

Remove the suspected cause of the decompensation.

Pausing the continuous IV fluid infusion prevents additional fluid accumulation in the lungs.

Continuing fluids in the presence of pulmonary edema will worsen the client's respiratory failure.

Gather data and escalate.

Checking oxygen saturation and lung sounds provides specific data to report to the RN, who must be alerted immediately to initiate medical interventions (like diuretics or advanced oxygen therapy).

The client is unstable, requiring prompt RN and provider involvement.

Cevap

The correct measures include assigning a negative-pressure room, wearing a fit-tested N95 respirator, donning a gown and clean gloves before entering, and placing a surgical mask on the client during transport.

Disseminated herpes zoster is highly contagious and transmitted via both airborne and contact routes until the lesions are completely dry and crusted. The correct interventions include isolating the client in a negative-pressure room, wearing an N95 respirator to prevent inhalation of airborne particles, donning a gown and gloves to prevent contact transmission, and placing a surgical mask on the client during necessary transport to contain respiratory secretions.

Adım Adım Çözüm

Identify the mode of transmission for disseminated herpes zoster.

Disseminated herpes zoster requires both airborne and contact precautions.

The varicella-zoster virus can be transmitted through the air and by direct contact with the fluid from the blisters.

Determine the appropriate room assignment and PPE for airborne and contact precautions.

A negative-pressure room, an N95 respirator, a gown, and gloves are required.

Negative pressure prevents airborne spread to the hallway; the N95 filters infectious particles; the gown and gloves prevent contact transmission.

Identify the appropriate protocol for transporting the client and doffing PPE.

The client must wear a standard surgical mask during transport; the nurse must doff the N95 outside the room.

The client's mask contains their respiratory secretions. The nurse must exit the contaminated environment before removing respiratory protection.

Evaluate the UAP delegation task.

Assessing lesion characteristics cannot be delegated to a UAP.

Clinical assessments require nursing judgment and are outside the UAP's scope of practice.

Cevap: Obtain a full set of vital signs including an apical pulse and immediately notify the registered nurse.

Cevap

The practical nurse should obtain a full set of vital signs including an apical pulse and immediately notify the registered nurse.

Prolonged nasogastric suctioning places a client at high risk for hypokalemia and metabolic alkalosis due to the excessive loss of gastric fluids. The client's symptoms of muscle weakness, severe calf cramps, and a "skipping" heartbeat are classic manifestations of hypokalemia, which can lead to life-threatening cardiac dysrhythmias. The practical nurse must immediately obtain baseline cardiovascular data, specifically an apical pulse, and urgently notify the registered nurse so that a 12-lead ECG and potassium replacement can be prescribed.

Adım Adım Çözüm

Analyze the client's symptoms and history.

The client has a history of prolonged NG tube suctioning and is presenting with muscle weakness, leg cramps, and palpitations.

Prolonged gastric suctioning removes potassium-rich fluids from the stomach, placing the client at high risk for severe hypokalemia.

Prioritize the physiological cues.

The "skipping" heartbeat (palpitations) combined with muscle weakness indicates a potential cardiac dysrhythmia due to electrolyte imbalance.

According to the ABCs (Airway, Breathing, Circulation), a potential cardiac issue takes precedence over muscle discomfort.

Determine the appropriate action within the practical nursing scope of practice.

The nurse must collect focused immediate data (vital signs and apical pulse) and report the critical change to the RN.

The RN and healthcare provider need baseline hemodynamic data to initiate emergency electrolyte replacement protocols.

Cevap: Maintain an abduction wedge or pillow between the client's lower extremities while resting in bed.; Suspend the client's heels off the mattress surface using soft pillows.; Slide a low-profile fracture pan under the client for elimination needs.

Cevap

The correct interventions are maintaining an abduction wedge between the legs, suspending the heels off the mattress, and using a low-profile fracture pan.

Appropriate basic care for a client recovering from a posterior total hip arthroplasty includes measures that maintain proper alignment and prevent pressure injuries. An abduction wedge prevents dangerous leg crossing (adduction). Suspending heels protects vulnerable skin from pressure ulcers. Using a fracture pan minimizes lifting and prevents the hip from flexing dangerously to 90 degrees or beyond.

Adım Adım Çözüm

Identify the surgical procedure and its specific post-operative precautions.

The client had a right total hip arthroplasty using a posterior approach, which requires avoiding hip flexion of 90 degrees or greater, adduction (crossing the midline), and internal rotation.

Understanding joint precautions is essential to prevent dislocation of the prosthesis.

Evaluate each intervention against basic care principles and hip precautions.

Abduction wedges prevent adduction. Heel suspension prevents pressure ulcers. Fracture pans prevent excessive hip flexion. However, side-lying on the operative side and 90-degree bed elevation violate positioning precautions.

Applying knowledge of safe positioning ensures client safety and promotes comfort.

Determine if delegated tasks fall within the legal scope of practice.

Evaluating skin integrity is an assessment task that cannot be delegated to unlicensed assistive personnel.

Cevap

Notify the supervising registered nurse about the altered vital signs and physical symptoms

The client is exhibiting early signs of hypovolemic shock, evidenced by tachycardia and a significant drop in blood pressure from the baseline, along with abdominal tightness. These are potential indicators of internal bleeding following abdominal surgery. While right shoulder pain can be an expected finding due to retained carbon dioxide, the combination of these vital sign changes requires immediate escalation to the registered nurse for urgent evaluation and intervention.

Adım Adım Çözüm

Analyze the client's symptoms and vital signs.

The client has right shoulder pain, abdominal tightness, tachycardia (106/min), and relative hypotension (102/64 mm Hg) compared to a baseline blood pressure of 136/78 mm Hg.

Recognizing deviations from baseline is essential for the early identification of postoperative complications.

Differentiate expected postoperative findings from potential emergencies.

While shoulder pain can be a benign result of carbon dioxide used during laparoscopy, the accompanying abdominal tightness, significantly increased heart rate, and decreased blood pressure strongly point toward internal hemorrhage.

Hypovolemia from internal bleeding presents with compensatory tachycardia and dropping blood pressure, which takes priority over benign gas pain.

Determine the appropriate nursing action within the practical nurse scope of practice.

The practical nurse must immediately escalate these critical findings to the registered nurse for a comprehensive assessment and provider notification.

Cevap: Withhold the prescribed cefuroxime and notify the registered nurse (RN) or healthcare provider due to the client's allergy history.; Inform the RN that the intravenous (IV) furosemide prescription requires administration by a registered nurse.

Cevap

The correct actions indicate withholding the cefuroxime due to the severe penicillin allergy and notifying the RN that the IV push furosemide is outside the PN scope of practice.

Safe pharmacological practice requires synthesizing multiple data points before administration. The practical nurse must recognize that an anaphylactic allergy to penicillin strictly contraindicates the use of cephalosporins (like cefuroxime) due to cross-sensitivity. Furthermore, the PN must practice within legal boundaries; because IV push administration is an RN-level skill in most jurisdictions, the PN correctly communicates this limitation to the RN to ensure the client receives the furosemide safely.

Adım Adım Çözüm

Analyze the cefuroxime prescription against the client's allergy profile.

Cefuroxime is a cephalosporin. The client has an anaphylactic allergy to penicillin, posing a high risk for cross-sensitivity.

Administering a cephalosporin to a client with a severe penicillin allergy is a critical safety risk requiring the medication to be withheld.

Evaluate the furosemide prescription against the PN scope of practice.

The healthcare team is coordinating the transfer of a client diagnosed with *Haemophilus influenzae* type b (Hib) meningitis to a different unit. Which action by the practical nurse demonstrates the correct infection control procedure for this client's transport?

Ensure the transport personnel wear fit-tested N95 respirators.

Instruct the receiving unit to prepare a negative-pressure isolation room.

Place a standard surgical mask on the client before leaving the room.

Cover the client's transport stretcher completely with a clean, impermeable sheet.

Cevabı ve açıklamayı göster

Cevap: Place a standard surgical mask on the client before leaving the room.

Cevap

Place a standard surgical mask on the client before leaving the room.

*Haemophilus influenzae* type b (Hib) meningitis requires droplet precautions. When transporting a client on droplet precautions outside of their room, placing a standard surgical mask on the client acts as source control, containing the large respiratory droplets and preventing transmission to the environment and other individuals.

Adım Adım Çözüm

Identify the transmission route for the specified pathogen.

*Haemophilus influenzae* type b (Hib) meningitis is transmitted via large respiratory droplets.

Determining the specific mode of transmission dictates which category of isolation precautions must be applied.

Determine the required protocol for client transport under droplet precautions.

The standard protocol requires the client to wear a standard surgical mask during transport.

Source control by masking the client is the most effective way to prevent the spread of large infectious droplets to others in hallways and common areas.

Cevap: A platelet count that decreases from 230,000/mm³ to 90,000/mm³; The client reports a sudden onset of sharp chest pain and difficulty breathing; A heart rate of 118 beats per minute and a blood pressure of 88/54 mm Hg

Cevap

The correct findings to escalate are the significant drop in platelets, the sudden onset of chest pain and difficulty breathing, and the tachycardia combined with hypotension.

The correct findings to escalate involve recognizing signs of severe complications related to both the underlying disease and the treatment. A significant decrease in platelets strongly suggests heparin-induced thrombocytopenia (HIT). Sudden chest pain and difficulty breathing are classic indicators that the DVT may have dislodged and caused a pulmonary embolism. Furthermore, tachycardia and hypotension in a client on anticoagulants indicate potential internal hemorrhage or shock. All of these require emergency RN and provider intervention.

Adım Adım Çözüm

Evaluate the current laboratory values, specifically the platelet count.

The platelet count dropped significantly to 90,000/mm³.

A drop below 150,000/mm³ during heparin therapy indicates heparin-induced thrombocytopenia (HIT).

Assess the client's respiratory and cardiovascular status.

Sudden chest pain, dyspnea, tachycardia, and hypotension are present.

These are classic signs of life-threatening complications such as pulmonary embolism and hemorrhagic shock.

Review the activated partial thromboplastin time (aPTT) results.

The aPTT is 60 seconds (2 times the control of 30 seconds).

This is a therapeutic value for continuous heparin infusion, demonstrating the treatment is effective and safe.

Assess the localized signs of the deep vein thrombosis (DVT).

The right calf remains warm, red, and swollen.

These are expected baseline findings for a DVT and do not indicate a new emergency.

Reassure the family that postoperative confusion is a normal expectation for an older adult.

Cevabı ve açıklamayı göster

Cevap: Notify the registered nurse immediately to report the changes in condition.

Cevap

Notify the registered nurse immediately to report the changes in condition.

The correct action identifies the urgent need for clinical escalation. The client's new-onset disorientation, restlessness, tachycardia (114 beats/min), and mild hypotension (96/54 mm Hg) represent a cluster of subtle, early signs of acute decompensation, such as hypovolemic or septic shock. Within the practical nurse scope of practice, recognizing this physiological instability requires immediately notifying the registered nurse so that rapid, collaborative interventions can be initiated to restore adequate tissue perfusion.

Adım Adım Çözüm

Analyze the clinical data presented in the scenario.

A 78-year-old postoperative client has new-onset restlessness, disorientation, tachycardia (114 beats/min), and mild hypotension (96/54 mm Hg).

Identifying all abnormal findings is the first step in data collection.

Interpret the clinical significance of the findings.

While the family suspects pain, the cluster of altered mental status and borderline hemodynamics strongly suggests poor tissue perfusion and the early stages of shock.

Distinguishing between expected postoperative discomfort and life-threatening physiological adaptation is crucial for client safety.

Determine the priority nursing action based on scope of practice.

The practical nurse must immediately escalate the situation to the registered nurse.

Acute, unstable physiological changes require comprehensive assessment and rapid collaborative intervention beyond the practical nurse's independent scope.

Cevap: Assist the individual into a prone position for 20 to 30 minutes several times daily.

Cevap

Assist the individual into a prone position for 20 to 30 minutes several times daily.

Following a lower extremity amputation, clients are at high risk for developing flexion contractures of the hip and knee, which can severely interfere with future prosthetic fitting and ambulation. Placing the client in a prone position for 20 to 30 minutes, 3 to 4 times a day, extends the hip and knee joints, stretches the flexor muscles, and prevents contracture formation. This is a critical basic care intervention for these clients.

Adım Adım Çözüm

Identify the client's postoperative timeframe and surgical procedure (Below-the-knee amputation, 48 hours post-op).

The acute risk of severe edema has decreased (which is highest in the first 24 hours), and the primary risk is now flexion contractures of the hip and knee.

Postoperative priorities for amputations shift from edema control in the immediate postoperative period to contracture prevention thereafter.

Evaluate each positioning option for contracture risk.

Continuous elevation, placing items underneath the knee, and prolonged sitting all promote joint flexion.

Joints left in a flexed position for extended periods will adapt and shorten, developing contractures that impair future prosthesis use.

Select the intervention that actively extends the vulnerable joints.

The prone positioning strategy is selected.

Lying prone forces the hip and knee joints into extension, stretching the flexor muscles and directly counteracting contracture formation.

Cevap

The correct actions include alerting the charge nurse of the upward trending heart rate, communicating the critically low hemoglobin result without delay, and scanning the identification band while verbally verifying the date of birth before administering medication.

These actions correctly identify and escalate subtle signs of shock and critical laboratory values while strictly adhering to safety protocols for medication administration. Prompt escalation allows the registered nurse and healthcare provider to intervene early in the event of an active hemorrhage.

Adım Adım Çözüm

Analyze the clinical scenario

The client has a suspected gastrointestinal hemorrhage, placing them at high risk for hypovolemic shock, severe anemia, and sudden clinical deterioration.

Understanding the underlying pathology helps prioritize assessment findings and identify which data require immediate escalation.

Evaluate the assessment findings and laboratory data for critical thresholds

A heart rate increasing from 84 to 110 bpm and a hemoglobin of 6.8 g/dL both indicate worsening hemorrhage and require immediate escalation.

Early recognition of shock (tachycardia) and critical labs (severe anemia) reduces the risk of cardiovascular collapse.

Differentiate between actions within the PN scope of practice and those that exceed it

Reporting findings and utilizing medication safety systems are within the PN scope, whereas independently titrating IV fluids is outside the PN scope.

Maintaining client safety requires the practical nurse to act strictly within legal and professional boundaries.

A school-aged child who weighs $33\text{ lbs}$ requires antipyretic therapy. The healthcare provider prescribes oral ibuprofen at $10\text{ mg/kg/dose}$ every $6\text{ hours}$ . The pharmacy dispenses an ibuprofen oral suspension with a concentration of $100\text{ mg}$ per $5\text{ mL}$ . Calculate the volume, in milliliters ( $\text{mL}$ ), the practical nurse should administer for a single dose. Record the answer to the nearest tenth. Do not include units in your answer.

Cevabı ve açıklamayı göster

Cevap: 7.5

Cevap

7.5

To determine the correct volume, the nurse must first convert the child's weight to kilograms (

33\text{ lbs} \div 2.2 = 15\text{ kg}

). Next, the weight is multiplied by the prescribed dosage parameter (

15\text{ kg} \times 10\text{ mg/kg} = 150\text{ mg}

). Finally, using the desired-over-have method, the liquid volume is calculated:

(150\text{ mg} \div 100\text{ mg}) \times 5\text{ mL} = 7.5\text{ mL}

. The value is exactly

7.5

, so it meets the requirement of being recorded to the nearest tenth.

Adım Adım Çözüm

Convert the patient's weight from pounds to kilograms.

33\text{ lbs} \div 2.2\text{ lbs/kg} = 15\text{ kg}

Standard pediatric medication dosages are calculated based on weight in kilograms.

Calculate the total required dose in milligrams.

15\text{ kg} \times 10\text{ mg/kg} = 150\text{ mg}

The prescribed dose must be multiplied by the patient's body weight to find the individualized dose.

Calculate the final liquid volume to administer based on the pharmacy's concentration.

\frac{150\text{ mg}}{100\text{ mg}} \times 5\text{ mL} = 7.5\text{ mL}

The ordered milligram dose must be converted into the administrable liquid volume.

A practical nurse has completed providing care for a client placed on airborne and contact precautions due to disseminated herpes zoster. The nurse is currently wearing an N95 respirator, an isolation gown, and gloves. In what order should the nurse perform the following actions to safely remove the personal protective equipment (PPE)? Arrange the steps from first to last.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence for doffing PPE in this scenario is: remove gloves, remove gown, perform hand hygiene and exit the room, remove the N95 respirator outside the room, and perform a final hand hygiene.

The Centers for Disease Control and Prevention (CDC) guidelines for removing PPE require the most contaminated items to be removed first. Gloves are removed initially, followed by the gown. Because the client requires airborne precautions, the N95 respirator must remain on until the nurse has exited the room and closed the door. Hand hygiene is essential both before exiting the room (to avoid contaminating the door handle) and after removing the respirator.

Adım Adım Çözüm

Remove gloves

Gloves are safely discarded in the room.

Gloves are the most contaminated item and are removed first to prevent transfer of pathogens to the body or environment.

Remove the isolation gown

Gown is rolled inside out and discarded in the room.

The front and sleeves of the gown are contaminated. Removing it inside the room prevents spreading contact pathogens into the hallway.

Perform hand hygiene and exit the room

Hands are clean before touching the door.

This prevents contaminating the doorknob and the environment outside the isolation room.

Remove the N95 respirator outside the room

Respirator is safely removed and discarded.

Airborne pathogens can remain suspended in the air. The respirator must stay in place until the nurse is completely outside the contaminated airspace.

Perform final hand hygiene

Hands are completely sanitized.

Touching the straps of the respirator during removal may transfer small amounts of pathogens to the hands.
