Cevap: A right side-lying position with a small rolled towel placed directly under the puncture site

Cevap

The correct position is a right side-lying position with a small rolled towel placed directly under the puncture site.
Following a percutaneous liver biopsy, the primary risk is hemorrhage because the liver is a highly vascular organ. Placing the client in a right side-lying position with a small towel or pillow under the puncture site applies direct external pressure to the liver capsule and the biopsy tract. This pressure promotes hemostasis and significantly reduces the risk of internal bleeding.

Adım Adım Çözüm

1
Analyze the procedure performed and identify the primary post-procedural complication risk.
The client had a percutaneous right liver biopsy. The liver is a highly vascular organ, making internal hemorrhage the most significant immediate post-procedural risk.
Identifying the highest risk dictates the necessary preventative nursing interventions for basic care and comfort.
2
Determine the physiological effect of positioning on the right-sided biopsy site.
Placing the client on their right side with a towel underneath applies direct, sustained external pressure to the liver capsule and the biopsy puncture tract.
Direct pressure promotes hemostasis and minimizes the risk of bleeding.
3
Evaluate the alternative positions for their impact on hemostasis.
Left side-lying, supine, and semi-Fowler's positions fail to apply pressure to the right-sided puncture site.
While these positions may address other generalized needs, they do not prevent the specific and critical complication of hemorrhage following this procedure.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence is to halt the feeding pump, turn the client to a lateral position, suction the airway, assess vital signs, and report the event to the charge nurse.
According to the ABC (Airway, Breathing, Circulation) priority framework, the immediate focus during an active aspiration event is to remove the source of the problem and protect the airway. Halting the feeding pump stops additional formula from entering the lungs. Turning the client to a lateral decubitus position uses gravity to drain emesis and prevent further aspiration of stomach contents. Clearing the upper airway with oropharyngeal suctioning removes any residual fluid that could be inhaled. Once the airway is stabilized and the immediate life threat is resolved, assessing vital signs and pulse oximetry provides critical data about the client's physiological adaptation. Finally, the practical nurse must report the acute event and the gathered assessment data to the supervising charge nurse or registered nurse for further medical evaluation.

Cevap

The correct priority order is to first stop the continuous enteral feeding pump, then turn the client to a side-lying position, next suction the oropharynx, apply supplemental oxygen, and finally notify the registered nurse (RN).
In any acute aspiration event associated with a continuous infusion, the nurse must first stop the source of the problem (the feeding pump). Next, the nurse must immediately protect the airway by utilizing gravity (side-lying position) to allow emesis to drain. Once positioned, the nurse suctions the oropharynx to actively clear residual fluid. Only after the airway is patent and clear should supplemental oxygen be applied to treat the hypoxia. Finally, after these rapid, life-saving bedside interventions are implemented, the nurse must notify the RN and healthcare provider for further assessment and orders.

Based on these findings, which of the following is the priority action for the practical nurse?

Cevabı ve açıklamayı göster

Cevap: Notify the registered nurse (RN) immediately regarding the vital signs and pain.

Cevap

The priority action is to immediately notify the registered nurse (RN) regarding the assessment findings, as they strongly indicate a developing retroperitoneal hemorrhage.
The client is exhibiting classic signs of a retroperitoneal hemorrhage, a severe complication of femoral artery access. When the posterior wall of the femoral artery leaks, blood tracks backward into the retroperitoneal space. Because the blood pools internally, the anterior groin dressing will often remain dry and intact. The expanding hematoma puts pressure on the surrounding nerves, causing persistent lower back or flank pain. This localized pain, combined with the systemic signs of developing hypovolemic shock (hypotension and tachycardia), constitutes a life-threatening emergency. The practical nurse must immediately escalate these findings to the RN or healthcare provider for advanced medical intervention.

Adım Adım Çözüm

1
Analyze the vital sign trends over the postoperative period.
The blood pressure has dropped significantly from 142/86 to 104/62 mm Hg, and the heart rate has increased from 78 to 116/min.
Identifying tachycardia and hypotension is the first step in recognizing developing hypovolemic shock.
2
Correlate the physical symptoms with the physiological data and the procedure type.
New-onset lower back pain following a femoral cardiac catheterization, combined with shock-like vital signs, strongly indicates a retroperitoneal hemorrhage.
Blood from the femoral artery can leak backward into the retroperitoneal space, causing severe back pain even while the anterior groin dressing remains dry.
3
Determine the most appropriate action within the practical nursing scope.
Escalate the findings immediately to the registered nurse (RN).
A retroperitoneal hemorrhage is a life-threatening emergency requiring advanced RN assessment, rapid fluid resuscitation, and immediate provider intervention.

Upon receiving a lethargic client from the post-anesthesia care unit following a tonsillectomy, the practical nurse must establish a safe resting position. Which positioning strategy should the nurse use to facilitate the drainage of oral secretions and prevent aspiration?

Cevabı ve açıklamayı göster

Cevap: Side-lying position with the head slightly elevated

Cevap

The side-lying position with the head slightly elevated is the correct choice to protect the airway.
The correct positioning strategy utilizes a side-lying posture. This is a fundamental basic care measure because it uses gravity to facilitate the natural drainage of saliva and potential bleeding out of the mouth. This is especially critical while the client remains lethargic from anesthesia and lacks intact airway clearance reflexes.

Adım Adım Çözüm

1
Identify the client's current physiological status and primary risks.
The client is lethargic from anesthesia and has just undergone oral surgery (tonsillectomy).
Recognizing the altered level of consciousness and surgical site highlights a severe risk for aspiration of blood and saliva.
2
Determine the physical principles necessary for airway clearance.
Gravity must be used to move fluids outward rather than allowing them to pool in the back of the throat.
A lethargic client cannot reliably swallow or clear their own airway through coughing.
3
Select the position that best utilizes gravity for drainage.
A side-lying (lateral) or partially prone position naturally directs fluids out of the mouth.
This positioning strategy prevents the accumulation of secretions over the trachea, ensuring safe basic care and comfort.

Cevap: Auscultate the client's lung fields for adventitious breath sounds

Cevap

The practical nurse should prioritize auscultating the client's lung fields for adventitious breath sounds to assess for pulmonary edema.
The client is exhibiting early signs of fluid volume overload and impending pulmonary edema, characterized by a new cough, restlessness (an early indicator of hypoxia), tachycardia, and elevated blood pressure. Given the client's history of congestive heart failure and the continuous IV fluid administration, the practical nurse must prioritize airway and breathing. Auscultating the lungs for crackles provides critical focused data that must be immediately reported to the registered nurse or provider for prompt medical intervention.

Adım Adım Çözüm

1
Analyze the client's clinical presentation and medical history.
The client has a history of congestive heart failure, is receiving continuous IV fluids, and now presents with a new dry cough, restlessness, tachycardia, and hypertension.
Identifying risk factors and early clinical signs is essential for recognizing complications such as fluid volume overload.
2
Apply prioritization frameworks, specifically Airway, Breathing, and Circulation (ABC).
The sudden onset of a cough and restlessness (which is a classic early sign of hypoxia) indicates a potential breathing and airway compromise.
ABC prioritization dictates that respiratory distress must be assessed and addressed before implementing comfort measures or routine monitoring.
3
Determine the most appropriate immediate action within the practical nursing scope of practice.
Auscultating lung sounds allows the nurse to collect critical focused data (e.g., crackles) to report immediately to the registered nurse or healthcare provider.

Cevap

The correct priority sequence is to clamp the catheter, position the client in the left lateral Trendelenburg position, administer oxygen, activate the emergency response team, and finally obtain vital signs.
In the event of a disconnected central venous catheter accompanied by sudden respiratory distress, the nurse must suspect an air embolism. The immediate priority is risk reduction by stopping the source of harm. Clamping the catheter prevents more air from entering the heart. Positioning the client on their left side with the head down (Durant's maneuver) traps the air in the right ventricle, preventing it from blocking the pulmonary artery. Oxygen is then applied to treat severe ischemia. Only after these immediate physical stabilization steps are complete should the nurse call for emergency assistance and gather vital signs.

Adım Adım Çözüm

1
Clamp the central venous catheter.
Stops further entrainment of room air into the vascular system.
Air embolism is a mechanical obstruction; stopping the source is always the immediate first step.
2
Place in left lateral Trendelenburg.
Displaces the air away from the right ventricular outflow tract.
Gravity causes the lighter air to rise to the apex of the right ventricle, keeping the pulmonary artery clear for blood flow.
3
Administer oxygen.
Reverses hypoxemia and promotes nitrogen washout.
The client is showing signs of severe respiratory distress due to impaired perfusion.
4
Activate emergency response.
Brings advanced providers and equipment to the bedside.
The client requires critical care, but the nurse must secure the airway and circulation with basic measures first.

This is an essential basic care measure for preventing hip flexion contractures following an above-the-knee amputation, which ensures the client will be able to properly use a prosthesis during rehabilitation.

Adım Adım Çözüm

1
Identify the client's post-operative timeline and surgical procedure.
The client is 48 hours post-above-the-knee amputation.
Nursing care protocols for amputations change significantly after the first 24 hours, specifically regarding limb elevation.
2
Determine the primary complication associated with immobility for this specific surgery.
The highest musculoskeletal risk is the development of a hip flexion contracture.
Contractures limit range of motion and can severely impede or prevent successful prosthetic fitting and rehabilitation.
3
Select the nursing intervention that directly counteracts this risk.
Positioning the client prone.
The prone position fully extends the hip joint, actively preventing the muscles and ligaments from contracting into a flexed position.

During morning rounds, a practical nurse reviews the electronic health record of a client diagnosed with bipolar disorder and hypertension. The client was admitted overnight for severe viral gastroenteritis with persistent vomiting and diarrhea. The morning laboratory results reveal a serum sodium level of 128 mEq/L128\text{ mEq/L} (128 mmol/L128\text{ mmol/L}). The client is scheduled to receive their routine oral lithium carbonate and oral hydrochlorothiazide in 30 minutes. Current vital signs indicate a heart rate of 115 beats/min115\text{ beats/min} and a blood pressure of 94/58 mm Hg94/58\text{ mm Hg}. Based on the client's clinical presentation, which action is the priority for the practical nurse?

Cevap: Withhold both medications and immediately notify the registered nurse of the client's laboratory results and vital signs.

Cevap

Withhold both medications and immediately notify the registered nurse of the client's laboratory results and vital signs.
The correct action demonstrates a synthesis of pharmacological knowledge, interpretation of clinical data, and safe practice boundaries. The client's vital signs (tachycardia, hypotension) and history of severe gastrointestinal losses indicate significant fluid volume deficit. Furthermore, the serum sodium level is critically low (128 mEq/L128\text{ mEq/L}). Lithium clearance is directly tied to sodium balance; hyponatremia causes the kidneys to aggressively retain lithium, leading to acute, life-threatening toxicity. Hydrochlorothiazide is a potassium- and sodium-wasting diuretic that would further exacerbate both the hyponatremia and the hypovolemia, compounding the risk of lithium toxicity. The safest and most appropriate action within the practical nurse scope of practice is to withhold both dangerous medications and immediately escalate the critical findings to the registered nurse.

Adım Adım Çözüm

1
Analyze the client's vital signs and clinical presentation.
The client has a history of severe vomiting and diarrhea, a heart rate of 115 beats/min, and a blood pressure of 94/58 mm Hg, indicating significant dehydration and potential hypovolemia.
Recognizing fluid volume deficit is essential before administering any medications that affect fluid balance or renal clearance.
2
Interpret the morning laboratory values.
The serum sodium level is critically low at 128 mEq/L (normal is 135-145 mEq/L).
Electrolyte imbalances directly impact the pharmacokinetics of certain medications, particularly lithium.
3
Evaluate the scheduled medications against the current clinical data.
Hydrochlorothiazide is a diuretic that will worsen the dehydration and hyponatremia. Lithium excretion is heavily dependent on sodium levels; hyponatremia causes the kidneys to reabsorb lithium, leading to rapid toxicity.
Administering either medication under these conditions is strictly contraindicated.
4
Determine the priority nursing action within the practical nurse scope of practice.
The nurse must withhold both medications and immediately escalate the critical findings to the registered nurse or healthcare provider.
The practical nurse has a duty to advocate for client safety by withholding unsafe medications and reporting critical changes in condition to the supervising RN.

A client is admitted to the medical unit with active gastrointestinal bleeding. Upon admission, the client's blood pressure was 122/80 mm Hg and heart rate was 78 beats per minute. One hour later, the practical nurse observes that the client's blood pressure has decreased to 98/62 mm Hg and the heart rate has increased to 112 beats per minute. Which action should the practical nurse take first?

Cevabı ve açıklamayı göster

Cevap: Notify the registered nurse immediately.

Cevap

Notify the registered nurse immediately.
The correct action is to notify the registered nurse immediately. The client's decreasing blood pressure and increasing heart rate, in the context of active bleeding, are classic early indicators of hypovolemic shock. This requires urgent escalation and intervention to restore circulatory volume.

Adım Adım Çözüm

1
Analyze the client's current vital signs compared to their baseline.
The blood pressure has dropped and the heart rate has increased significantly.
Comparing current data to baseline helps identify trends in the client's physiological status.
2
Correlate the vital sign changes with the client's diagnosis.
The client has active gastrointestinal bleeding; the dropping blood pressure and rising heart rate suggest hypovolemic shock.
Recognizing the signs of circulatory compromise is a critical component of physiological adaptation.
3
Determine the highest priority action based on the PN scope of practice.
The most urgent action is to notify the RN or provider to initiate emergent treatment.
In acute emergencies, escalating care is necessary to protect the client's circulation (ABC prioritization).

Cevap

The correct sequence is: cleanse the perineum, begin voiding into the toilet, collect the midstream urine, and finally secure and label the container.
To obtain an uncontaminated midstream clean-catch urine specimen, the urethral meatus must first be cleansed from front to back to remove external bacteria. The client then initiates the urine stream into the toilet to flush the distal urethra of any remaining flora. The sterile container is then introduced into the midstream flow to capture the most representative bladder sample. Finally, the container is sealed to prevent leaks and properly labeled for accurate processing.

Adım Adım Çözüm

1
Identify the first action required to prevent contamination.
Cleanse the perineal area from front to back.
Reduces the number of bacteria surrounding the urethral meatus.
2
Determine the next step to further clear bacteria.
Begin voiding a small amount of urine into the toilet.
Flushes the distal urethra of remaining resident bacteria.
3
Identify when to collect the actual specimen.
Pass the sterile container into the urine stream.
The midstream portion contains the most accurate sample of bladder urine.
4
Determine the final steps for specimen handling.
Secure the lid and apply the client label.
