An adult client is recovering on the medical-surgical unit 4 hours after an ultrasound-guided percutaneous liver biopsy. The client is currently positioned on their right side and reports new-onset right shoulder pain along with feeling 'anxious.' The practical nurse assesses the client and notes a heart rate of 112 bpm, blood pressure of 104/62 mm Hg, and a respiratory rate of 22 breaths per minute. Baseline vitals before the procedure were a heart rate of 76 bpm, blood pressure of 136/78 mm Hg, and a respiratory rate of 14 breaths per minute. Based on these findings, which action is the priority for the practical nurse?

Cevabı ve açıklamayı göster

Cevap: Immediately alert the registered nurse of the clinical changes to initiate emergency escalation

Cevap

Immediately alert the registered nurse of the clinical changes to initiate emergency escalation
The correct action involves notifying the registered nurse immediately because the client is exhibiting classic signs of internal hemorrhage and early hypovolemic shock. Following a liver biopsy, the organ is highly vascular and prone to bleeding. The new-onset right shoulder pain is referred pain resulting from blood pooling and irritating the phrenic nerve under the diaphragm. Combined with increasing restlessness, a rising heart rate, and a dropping blood pressure compared to the baseline, these findings require immediate emergency escalation rather than independent nursing interventions.

Adım Adım Çözüm

1
Analyze the client's recent procedure (liver biopsy) and identify the primary post-procedure risk.
The highest risk following a percutaneous liver biopsy is internal hemorrhage due to the high vascularity of the liver.
Anticipating complications allows the nurse to interpret assessment data accurately.
2
Evaluate the new-onset symptoms of right shoulder pain and anxiety.
Anxiety is an early sign of hypoxia or shock. Right shoulder pain is referred pain caused by blood accumulating under the diaphragm and irritating the phrenic nerve.
Recognizing referred pain helps differentiate a severe complication from benign musculoskeletal discomfort.
3
Compare the current vital signs to the client's pre-procedure baseline.
The heart rate increased by 36 bpm and the systolic blood pressure dropped by 32 mm Hg. Combined with the symptoms, this indicates early compensatory hypovolemic shock.
Absolute vital sign numbers can be misleading; recognizing significant shifts from baseline is critical for detecting shock early.
4
Determine the safest and most appropriate intervention within the practical nurse's scope of practice.
The priority is to maintain the pressure-holding right lateral position and immediately escalate the critical findings to the registered nurse for emergency intervention.
The client requires rapid medical evaluation, fluid resuscitation, and potentially surgical intervention, which necessitates immediate escalation.

Cevap

The correct actions are to stay with the client and notify the registered nurse, assess for recent tyramine consumption, and ask about the use of over-the-counter sympathomimetic medications.
The client is experiencing an MAOI-induced hypertensive crisis, a medical emergency characterized by extreme blood pressure elevation and a throbbing headache. The practical nurse must prioritize safety by staying with the client, positioning them safely, and notifying the provider. Furthermore, gathering data about tyramine intake and over-the-counter sympathomimetic drugs is essential, as these are the primary triggers for this drug interaction.

Adım Adım Çözüm

1
Analyze the client's clinical presentation and current medications.
The client is taking an MAOI and presenting with a severely elevated blood pressure, tachycardia, and a throbbing headache, which strongly indicates a hypertensive crisis.
Recognizing the pattern of a critical adverse drug reaction is the first step in prioritizing care.
2
Determine appropriate immediate interventions within the practical nurse scope.
The nurse must stay with the client, elevate the head of the bed to reduce intracranial pressure, and escalate the emergency to the registered nurse or healthcare provider.
A hypertensive crisis is a life-threatening event requiring advanced medical intervention beyond the practical nurse's independent scope.
3
Identify data collection priorities to find the cause of the crisis.
The nurse should ask the client about common triggers, specifically the consumption of tyramine-rich foods or sympathomimetic medications (like decongestants).
Identifying the trigger helps the healthcare team confirm the diagnosis and prevent future occurrences once the client is stabilized.
4
Recognize and avoid unsafe or out-of-scope practices.
The nurse must not bypass safety protocols (like patient identification) or attempt to administer intravenous push medications.
Maintaining fundamental safety standards and adhering to scope of practice prevents further harm to the client.

Cevap: The client reports a new sensation of pressure at the surgical site and is frequently clearing their throat.; The client reports numbness and a tingling sensation around the mouth and fingertips.; The client's apical heart rate is 118118 beats per minute and blood pressure is 102/60102/60 mmHg.

Cevap

The findings that require immediate escalation are the sensation of neck pressure with frequent throat clearing, the numbness and tingling around the mouth, and the heart rate of 118 beats per minute with a blood pressure of 102/60 mmHg.
Following a subtotal thyroidectomy, the most critical risks include airway obstruction from a hematoma, hypocalcemia from parathyroid gland damage, and internal hemorrhage. Frequent throat clearing and a sensation of neck pressure are early, subtle signs of an expanding hematoma that physically threatens the airway. Numbness and tingling around the mouth (circumoral paresthesia) are classic early manifestations of hypocalcemia, which can progress to life-threatening tetany and laryngospasm. Unexplained tachycardia (118118 bpm) paired with borderline hypotension indicates potential internal bleeding and early hypovolemic shock. All three of these findings represent potential emergencies that exceed the practical nurse's scope of independent management and require immediate escalation to the registered nurse.

Adım Adım Çözüm

1
Analyze the surgical context and timeframe.
The client is 6 hours post-subtotal thyroidectomy.
Identifying the specific procedure highlights the primary risks: airway compromise (hematoma/edema), hypocalcemia (parathyroid injury), and postoperative hemorrhage.
2
Evaluate the respiratory and airway findings.
Frequent throat clearing and neck pressure indicate a potential hematoma, while mild hoarseness is an expected finding.
A rapidly expanding hematoma can compress the trachea, requiring emergency airway management, whereas intubation routinely causes temporary hoarseness.
3
Evaluate the neurological and laboratory findings.
Circumoral tingling indicates hypocalcemia (a critical complication), whereas a calcium level of 9.4 mg/dL is within normal limits.
Parathyroid gland disruption causes rapid calcium depletion, risking life-threatening tetany or seizures if not treated immediately.
4
Evaluate the hemodynamic and comfort findings.
Tachycardia (118 bpm) with borderline hypotension indicates early shock, whereas a pain level of 4/10 is expected.
Unrecognized internal bleeding leads to hypovolemic shock, requiring immediate fluid resuscitation and surgical evaluation by the RN and provider.

Cevap: Review the client's most recent serum potassium level prior to administering the scheduled dose of oral digoxin.; Collaborate with the registered nurse to administer the intravenous bumetanide and subsequently monitor the client's fluid output.

Cevap

The correct actions are to review the client's serum potassium level prior to administering the digoxin, and to collaborate with the registered nurse to administer the intravenous bumetanide while monitoring the client's fluid output.
The practical nurse demonstrates safe pharmacological practice by recognizing that loop diuretics like bumetanide deplete potassium, which requires checking serum potassium levels before giving digoxin to prevent toxicity. Furthermore, the nurse correctly identifies that intravenous push medications are outside the LPN/LVN scope of practice and collaborates with the RN for administration while monitoring therapeutic outcomes.

Adım Adım Çözüm

1
Analyze the client's clinical presentation and prescribed medications.
The client has a high fever (102.4°F), requires an IV push loop diuretic (bumetanide), an oral cardiac glycoside (digoxin), a weight-based antibiotic, and an immunization.
Identifying the clinical context is essential for prioritizing care and recognizing safety contraindications.
2
Evaluate the scope of practice regarding intravenous medications.
The PN determines that administering IV push bumetanide is out of scope and must be delegated to or performed by the RN.
LPN/LVNs are generally prohibited from administering IV push medications due to the rapid systemic onset and required advanced assessment capabilities.
3
Assess pharmacological interactions between the prescribed medications.
Bumetanide is a loop diuretic that depletes potassium, which subsequently increases the risk of digoxin toxicity.
The PN must ensure the serum potassium is normal before giving digoxin to prevent fatal cardiac dysrhythmias.
4
Determine the appropriateness of the influenza immunization.
The PN recognizes that a severe acute febrile illness is a contraindication and the vaccine must be withheld.
Administering vaccines during acute febrile illness can exacerbate symptoms or mask adverse vaccine reactions.
5
Apply the rights of medication administration and basic dosage calculation rules.
The PN identifies that two active identifiers are always required, and that a weight already in kilograms should not be divided by 2.2.
Bypassing safety checks or misapplying conversion factors leads to critical medication administration errors.

1
Review the newly prescribed medication and the client's medical history.
The nurse identifies that the client is prescribed amoxicillin and has a severe allergy to penicillin.
Checking the client's chart for allergies is a critical first step in safe medication administration.
2
Correlate the prescribed medication class with the client's allergy.
The nurse recognizes that amoxicillin is a penicillin-class antibiotic.
Understanding drug classifications prevents the administration of cross-reactive allergens.
3
Determine the safest clinical action based on the findings.
The nurse decides the medication cannot be safely given.
Administering the drug could trigger life-threatening anaphylaxis.
4
Execute the appropriate nursing intervention.
The nurse withholds the dose and contacts the provider to obtain an alternative antibiotic.
The provider must be notified to ensure the client receives safe, timely, and appropriate treatment for their infection.

Cevabı ve açıklamayı göster

Cevap: An apical heart rate of 54 beats per minute; A serum potassium level of 3.0 mEq/L; The client reports a new onset of nausea and blurred vision

Cevap

The practical nurse should withhold the digoxin for an apical pulse less than 60 beats per minute (54 beats per minute), a low potassium level (3.0 mEq/L), and signs of toxicity (nausea and blurred vision).
Digoxin is a cardiac glycoside that slows the heart rate and strengthens cardiac contractility. Because of its narrow therapeutic index, the nurse must ensure the apical pulse is 60 beats per minute or greater, the potassium level is within the normal range (3.5 to 5.0 mEq/L), and the client is free from toxicity symptoms (like gastrointestinal upset or visual changes) before safely administering the dose.

Adım Adım Çözüm

1
Evaluate the client's apical heart rate against safe administration parameters.
The apical rate is 54 beats per minute, which is below the safe threshold of 60 beats per minute for an adult.
Digoxin slows down the heart rate; administering it to a bradycardic client can cause severe and life-threatening dysrhythmias.
2
Analyze the client's laboratory values, specifically focusing on the potassium level.
The potassium level is 3.0 mEq/L, indicating hypokalemia.
Low potassium levels increase the binding of digoxin to cardiac muscle cells, significantly heightening the risk for toxicity even when normal doses are given.
3
Assess the client for subjective symptoms indicating medication toxicity.
The client reports experiencing nausea and blurred vision.
These are classic early subjective indicators of digoxin toxicity and require immediate clinical intervention.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is: pull the skin laterally, insert the needle at a 90-degree angle, inject the medication slowly, wait 10 seconds, and finally withdraw the needle while simultaneously releasing the retracted skin.
The Z-track method is essential for medications that cause tissue irritation or staining. The procedure begins by pulling the skin laterally to displace the tissue planes. While holding the skin in this position, the needle is inserted at a 90-degree angle and the medication is injected slowly. The nurse then waits 10 seconds to allow the medication to disperse within the muscle. Finally, the needle is withdrawn and the skin is released simultaneously, creating a zig-zag path that effectively seals the medication within the muscle belly.

Adım Adım Çözüm

1
Pull the overlying skin and subcutaneous tissue laterally 1 to 1.5 inches.
The skin and subcutaneous tissue are displaced from the underlying muscle.
This creates an offset pathway that will seal the needle track after the injection is complete.
2
Insert the needle smoothly and swiftly at a 90-degree angle.
The needle reaches the deep muscle tissue.
A 90-degree angle ensures the medication is deposited directly into the muscle belly rather than the subcutaneous layer.
3
Inject the medication slowly and steadily into the muscle.
The medication is deposited into the muscle tissue.
A slow injection rate minimizes tissue trauma and pain while allowing the muscle fibers to accommodate the fluid volume.
4
Wait 10 seconds before removing the needle.
The medication begins to disperse deeply into the muscle.
This pause prevents the medication from tracking back up the needle pathway immediately following the injection.
5
Withdraw the needle and immediately release the retracted skin.
The tissue planes slide back into their original, unretracted positions.
Releasing the skin breaks the alignment of the needle track, permanently trapping the medication in the muscle layer and preventing superficial staining or irritation.

The normal white blood cell (WBC) count is typically between 5,0005,000 and 10,000/mm310,000/\text{mm}^3. A count of 1,200/mm31,200/\text{mm}^3 indicates severe leukopenia, which places the client at a critical risk for infection. Within the practical nurse scope of practice, any critical laboratory value must be immediately escalated to the registered nurse or healthcare provider so that protective measures can be initiated.

Adım Adım Çözüm

1
Analyze the client's laboratory result.
The WBC count is 1,200/mm31,200/\text{mm}^3, which is significantly below the normal range of 5,0005,000 to 10,000/mm310,000/\text{mm}^3.
Identifying abnormal values is the first step in recognizing potential complications.
2
Determine the appropriate action based on the practical nurse's scope of practice.
The practical nurse must communicate critical findings to the registered nurse.
The registered nurse must assess the client and collaborate with the provider to implement necessary medical interventions, such as neutropenic precautions.

A client is resting in bed on the telemetry unit 4 hours after a diagnostic cardiac catheterization performed via the right femoral artery. During routine data collection, the client complains of a new, persistent ache in the lower back. Current vital signs show a blood pressure of 102/64 mm Hg and a pulse of 112 beats per minute, compared to a pre-procedure baseline of 134/78 mm Hg and 76 beats per minute. Which action should the practical nurse (PN) take first?

Cevap: Notify the registered nurse (RN) immediately about the assessment findings.

Cevap

Notify the registered nurse (RN) immediately about the assessment findings.
Following a femoral cardiac catheterization, the onset of new lower back pain combined with tachycardia and a dropping blood pressure are hallmark indicators of retroperitoneal hemorrhage. This is a critical circulatory emergency. Within the practical nurse scope of practice, recognizing these signs of hypovolemic shock necessitates immediate escalation to the registered nurse (RN) or healthcare provider for rapid medical intervention.

Adım Adım Çözüm

1
Analyze the client's post-procedure symptoms and vital sign trends.
The client has new lower back pain, hypotension, and tachycardia compared to baseline.
Identifying deviations from baseline is critical for recognizing early postoperative complications.
2
Correlate the findings with potential complications of a femoral arterial puncture.
These combined findings strongly suggest retroperitoneal bleeding, a severe circulatory compromise.
Blood leaking backward into the retroperitoneal space causes back pain and subsequent hypovolemia.
3
Determine the priority nursing intervention within the PN scope of practice.
The PN must immediately escalate these critical, unstable findings to the RN.
Life-threatening emergencies require rapid RN or provider intervention for fluid resuscitation and medical management.

Cevap: Resting heart rate of 118 beats/min; Capillary refill time of 5 seconds; Sudden onset of mild confusion and restlessness

Cevap

The findings indicating hypovolemic shock are a resting heart rate of 118 beats/min, a capillary refill time of 5 seconds, and a sudden onset of mild confusion and restlessness.
The correct options identify key systemic responses to decreased circulating blood volume. As intravascular fluid shifts into the interstitial space (third-spacing), the body compensates for the lack of volume by increasing the heart rate to maintain cardiac output. Peripheral vasoconstriction occurs to shunt blood to vital organs, resulting in delayed capillary refill. Additionally, decreased cerebral perfusion leads to early neurological changes, such as sudden confusion and restlessness.

Adım Adım Çözüm

1
Analyze the client's condition and risk factors.
The client has acute pancreatitis with fluid third-spacing, which pulls fluid out of the vascular space, creating a high risk for hypovolemic shock.
Understanding the pathophysiology of fluid shifts directs the nurse to look for specific signs of decreased circulating blood volume.
2
Evaluate the options for signs of compromised circulation and perfusion.
Tachycardia, delayed capillary refill (greater than 3 seconds), and neurological changes (confusion/restlessness) are identified as direct circulatory failure signs.
These findings reflect the body's compensatory mechanisms (increased heart rate, peripheral vasoconstriction) and the consequences of poor organ perfusion (cerebral hypoxia).
3
Differentiate expected local disease symptoms from systemic life-threatening complications.
The abdominal pain is identified as an expected local symptom of pancreatitis, while the elevated blood pressure contradicts the hemodynamics of shock.
Separating expected baseline symptoms from acute physiological deterioration ensures correct ABC prioritization.

Cevap

The correct sequence for mixing insulins is to roll the NPH vial, inject air into the NPH vial, inject air into the regular vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
To safely prepare a mixed dose of insulin, the nurse must follow the 'clear before cloudy' sequence. First, the NPH (cloudy) insulin is rolled to resuspend the particles. Then, air is injected into the NPH vial followed by the regular (clear) vial. The regular insulin is drawn up first to prevent contaminating the rapid-acting clear insulin with the longer-acting cloudy insulin. Finally, the NPH insulin is withdrawn.

Adım Adım Çözüm

1
Resuspend the intermediate-acting insulin.
The cloudy suspension is mixed evenly without bubbles.
Rolling rather than shaking prevents bubble formation, which can cause dosing errors.
2
Pressurize both vials with air, starting with the intermediate-acting (cloudy) insulin.
Air is placed in both vials, leaving the needle in the regular insulin vial.
Pressurizing prevents a vacuum. Starting with NPH prevents contaminating the regular insulin needle.
3
Draw up the insulins, starting with the short-acting (clear) insulin.
Regular insulin is drawn up first, followed by NPH insulin.
Drawing clear before cloudy ensures the regular insulin vial is not contaminated by intermediate-acting insulin.

A practical nurse is caring for a client who is recovering from a diagnostic cardiac catheterization performed via the right femoral artery approach. The client reports mild lower back discomfort and requests a change in position. Which action should the nurse take to promote comfort while maintaining safety?

Cevabı ve açıklamayı göster

Cevap: Elevate the head of the bed to 15 degrees while ensuring the right leg remains completely straight.

Cevap

Elevate the head of the bed to 15 degrees while ensuring the right leg remains completely straight.
The correct action balances the client's need for comfort with strict safety parameters. After a femoral artery approach, the hip must remain un-flexed to prevent bleeding. Elevating the head of the bed up to 30 degrees (15 degrees in this case) is permissible and can help alleviate lower back pain without compromising the arterial puncture site.

Adım Adım Çözüm

1
Analyze the client's clinical situation and current procedure.
The client had a cardiac catheterization via the right femoral artery, which carries a high risk of arterial bleeding at the groin site.
Identifying the procedure guides the necessary post-operative restrictions and safety precautions.
2
Evaluate the standard positioning constraints for a femoral access site.
The standard protocol requires keeping the affected leg straight and maintaining the head of the bed at an elevation no greater than 30 degrees.
Any significant flexion at the hip or groin can dislodge the clot and cause severe bleeding or a hematoma.
3
Determine the safest way to address the client's lower back discomfort within the given constraints.
Elevating the head of the bed to 15 degrees is within the safe limit (less than 30 degrees) and helps relieve back strain without compromising the straight alignment of the right leg.
This balances the client's basic comfort needs with strict physiological safety requirements.
