Cevap: Position the client in a lateral recumbent position with the knees drawn up to the abdomen during the procedure.; Verify the client's coagulation profile, including platelet count and prothrombin time, prior to the procedure.; Ensure that the client remains in a flat, supine position for the prescribed duration after the needle is withdrawn.

Cevap

The correct interventions are positioning the client laterally with knees drawn up during the procedure, verifying the coagulation profile beforehand, and maintaining a flat, supine position afterward.
Risk reduction for a lumbar puncture requires verifying coagulation studies to prevent hemorrhage, utilizing the lateral recumbent position to safely open intervertebral spaces during insertion, and maintaining a flat, supine position post-procedure to prevent cerebrospinal fluid leakage and subsequent spinal headaches.

Adım Adım Çözüm

1
Evaluate pre-procedure requirements for a lumbar puncture.
Coagulation studies must be verified to prevent bleeding complications like a spinal hematoma.
Invasive procedures carry a bleeding risk that must be mitigated prior to needle insertion.
2
Determine the optimal positioning during the procedure.
The lateral recumbent position with knees drawn up is necessary.
This position separates the vertebrae, providing safe and easier access to the subarachnoid space.
3
Identify correct post-procedure care to prevent complications.
The client must remain flat and supine for a prescribed duration.
Remaining flat minimizes cerebrospinal fluid leakage from the puncture site, preventing severe spinal headaches.
4
Rule out inappropriate or unsafe actions.
High-Fowler's position, delegating assessments to the UAP, and misinterpreting shock signs are rejected.
These actions directly compromise client safety and violate standards of nursing practice.

A client admitted with severe dehydration and hypokalemia has a prescription for an intravenous (IV) infusion of 40 mEq of potassium chloride (KCl) mixed in 1000 mL of 0.9% sodium chloride. Which action is essential for the nurse to perform when administering this parenteral therapy?

Cevabı ve açıklamayı göster

Cevap: Ensure the infusion rate is controlled by an electronic pump and does not exceed 10 mEq per hour.

Cevap

The nurse must use an electronic infusion pump to administer intravenous potassium chloride at a maximum safe rate of 10 mEq per hour.
Intravenous potassium chloride is a high-alert medication that must be administered meticulously. To prevent fatal cardiac dysrhythmias and severe vein irritation, it must always be delivered via an electronic infusion pump to ensure precise rate control. The standard maximum recommended safe rate through a peripheral intravenous line is 10 mEq per hour.

Adım Adım Çözüm

1
Analyze the prescribed medication and its safety parameters.
Potassium chloride is a high-alert medication that can cause fatal cardiac arrhythmias if administered too rapidly.
Recognizing high-alert parenteral medications is the critical first step in ensuring patient safety.
2
Evaluate the safe administration rate for the client's IV access.
The standard maximum safe infusion rate for IV potassium chloride through a peripheral line is 10 mEq per hour.
Exceeding this rate increases the risk of severe phlebitis and life-threatening hyperkalemia.
3
Determine the necessary equipment for safe delivery.
An electronic infusion pump must always be utilized for administration.
Gravity drips cannot guarantee the precise rate control strictly required for potassium infusions.

A nurse is caring for a client who sustained deep partial-thickness and full-thickness burns over 45% of their total body surface area (TBSA) 8 hours ago. Based on the physiological adaptations occurring during this emergent (resuscitative) phase, which of the following assessment findings should the nurse expect? Select all that apply.

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Hematocrit of 56%; Serum potassium of 6.2 mEq/L; Heart rate of 118 beats per minute

Cevap

The expected findings during the emergent phase of a severe burn are an elevated hematocrit, hyperkalemia, and tachycardia.
In the emergent phase of a severe burn, increased capillary permeability causes fluid to leak into the interstitial space. This leads to intravascular volume depletion, manifesting as hemoconcentration (elevated hematocrit) and compensatory tachycardia. Additionally, the destruction of cells releases large amounts of intracellular potassium into the bloodstream, causing hyperkalemia.

Adım Adım Çözüm

1
Analyze the pathophysiology of the emergent (resuscitative) phase of a major burn injury, which occurs in the first 24 to 72 hours.
Identify that this phase is characterized by a massive shift of fluids out of the intravascular space into the interstitial space, along with extensive cellular destruction.
Understanding the underlying fluid and electrolyte shifts is necessary to predict the expected clinical findings.
2
Evaluate each option against the expected physiological adaptations of burn shock.
Determine that intravascular fluid loss leads to hemoconcentration (elevated hematocrit), compensatory tachycardia, and a narrowing pulse pressure, while cell damage releases potassium (hyperkalemia). Tissue hypoxia leads to metabolic acidosis, not alkalosis.
This process systematically eliminates incorrect expectations and confirms the expected compensatory mechanisms and lab values.

Anahtar Kavram

During the emergent phase of severe burn injuries, physiological adaptations include massive third-spacing of fluid causing hemoconcentration and hypovolemic shock, cellular destruction causing hyperkalemia, and tissue hypoxia causing metabolic acidosis.

A nurse is reviewing diagnostic data for a 72-year-old client admitted with a severe exacerbation of chronic obstructive pulmonary disease (COPD). The client is currently receiving continuous oxygen therapy. Which of the following arterial blood gas (ABG) results represents an acute physiological decompensation that requires the most immediate intervention by the nurse?

Cevabı ve açıklamayı göster

Cevap: pH 7.26, PaCO2 72 mm Hg, HCO3 32 mEq/L, PaO2 50 mm Hg

Cevap

The ABG result showing a pH of 7.26, PaCO2 of 72 mm Hg, HCO3 of 32 mEq/L, and PaO2 of 50 mm Hg.
The values showing a pH of 7.26, PaCO2 of 72 mm Hg, HCO3 of 32 mEq/L, and PaO2 of 50 mm Hg indicate an acute-on-chronic respiratory acidosis with severe hypoxemia. Despite the elevated bicarbonate (indicating long-term renal compensation), the low pH demonstrates that the client's respiratory system is currently failing to maintain acid-base balance. This represents a life-threatening emergency requiring immediate respiratory support, such as noninvasive positive pressure ventilation (BiPAP) or intubation.

Adım Adım Çözüm

1
Determine the client's expected baseline based on their diagnosis.
Clients with severe COPD typically retain carbon dioxide, leading to chronic respiratory acidosis with metabolic compensation (normal pH, elevated PaCO2, elevated HCO3).
Establishing the baseline helps differentiate between a chronic stable state and an acute exacerbation.
2
Analyze each ABG result for uncompensated or acute changes.
Identify which set of values demonstrates a failure to maintain acid-base balance (abnormal pH) and profound oxygenation failure.
Acute physiological decompensation is marked by sudden shifts outside the body's compensatory mechanisms.
3
Prioritize the most life-threatening finding.
A significantly acidic pH combined with severe hypoxemia indicates impending respiratory arrest, requiring the highest priority intervention.
Airway and breathing emergencies take absolute precedence in risk reduction.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with donning a mask and directing the client's face away, followed by removing the old dressing. The nurse then transitions to sterile gloves, cleanses the site with chlorhexidine (allowing it to dry), and finally applies a new transparent occlusive dressing.
Changing a central line dressing requires strict adherence to sterile technique to prevent CLABSI. Masking protects the site from respiratory droplets. The old dressing is removed carefully toward the site to prevent dislodging the catheter. A sterile field is then established by donning sterile gloves. Chlorhexidine is applied with friction to destroy microorganisms and must dry completely to achieve its chemical antisepsis effect. Finally, a sterile occlusive dressing seals the site.

Adım Adım Çözüm

1
Don a face mask and instruct the client to turn their head away.
Respiratory droplets are directed away from the vulnerable area.
Applying airborne precautions reduces the immediate risk of bacterial contamination from the respiratory tract before the protective dressing is even removed.
2
Remove the old dressing by pulling the edges toward the insertion site.
The insertion site is safely exposed.
Pulling away from the insertion site could snag the catheter and accidentally pull it out. This step utilizes clean technique.
3
Discard the old dressing and clean gloves, perform hand hygiene, and don sterile gloves.
The nurse successfully transitions to strict sterile technique.
Once the site is exposed, maximum sterile barrier precautions are required to touch the site and apply the new antiseptic and dressing.
4
Scrub the insertion site with chlorhexidine using friction and allow it to air dry.
Skin flora and potential pathogens are eradicated.
Friction helps the antiseptic penetrate the epidermis, and chlorhexidine must air dry completely to achieve its maximum antimicrobial efficacy.
5
Apply a new sterile transparent occlusive dressing over the insertion site.
The catheter site is securely sealed.
An occlusive transparent dressing prevents environmental contamination while allowing continuous visualization of the site for early signs of infection.

The client abruptly gasps for breath, begins coughing violently, and reports acute, sharp chest pain. The client's lips appear cyanotic and oxygen saturation drops to 81%. What is the priority nursing action?

Cevabı ve açıklamayı göster

Cevap: Clamp the catheter immediately and place the client in a left lateral Trendelenburg position.

Cevap

The correct action is to immediately clamp the catheter and position the client in a left lateral Trendelenburg position.
Clamping the catheter immediately stops further air entry. Placing the client in a left lateral Trendelenburg position is the standard emergency medical intervention for an air embolism, as it traps the air in the right ventricle and prevents it from occluding the pulmonary circulation.

Adım Adım Çözüm

1
Identify the complication.
Recognize that an open central venous catheter hub accompanied by sudden, severe respiratory distress indicates a life-threatening air embolism.
Air rapidly enters the venous system due to negative intrathoracic pressure during inspiration.
2
Stop the source.
Clamp the central venous catheter.
Clamping the line instantly prevents any additional air from being drawn into the client's central circulation.
3
Position the client appropriately.
Place the client in the left lateral Trendelenburg position.
This specific position utilizes gravity to trap the air bubble in the apex of the right ventricle, preventing it from migrating forward into the pulmonary artery and causing a right ventricular outflow tract obstruction.

Cevap: Examine the surgical incision site and the drainage collection device for signs of active bleeding

Cevap

The highest priority action is to examine the surgical incision site and drainage collection device for signs of active bleeding.
The client is exhibiting classic signs of the compensatory stage of hypovolemic shock, which include a narrowing pulse pressure (20 mm Hg), tachycardia, tachypnea, unexplained restlessness, and cool skin due to peripheral vasoconstriction. Because this client is only two days postoperative, internal hemorrhage is a high-risk complication. The priority is to assess for the source of bleeding (such as the incision and drains) so that the healthcare provider can be alerted and fluid resuscitation can begin.

Adım Adım Çözüm

1
Analyze the client's vital signs and physical assessment findings.
The client presents with tachycardia (114 bpm), a narrow pulse pressure (104 - 84 = 20 mm Hg), tachypnea (22 breaths/min), restlessness, and cool skin.
Identifying abnormal physiological trends is the first step in recognizing clinical deterioration.
2
Correlate the findings with potential postoperative complications.
The combination of these specific signs strongly indicates the compensatory stage of hypovolemic shock, likely due to internal hemorrhage.
The sympathetic nervous system activates to maintain cardiac output through vasoconstriction (narrow pulse pressure, cool skin) and tachycardia.
3
Determine the highest priority nursing intervention.
The nurse must immediately assess for the source of the suspected bleeding to initiate appropriate medical management.
According to the ABCs (Airway, Breathing, Circulation), addressing a severe circulation deficit takes precedence over routine symptom management or delegation.

Cevap

The correct priority sequence is to first place the client in a high Fowler's position, followed by administering high-flow oxygen, obtaining vital signs, administering intravenous furosemide, and finally inserting an indwelling urinary catheter.
In acute pulmonary edema, the absolute priority is airway and breathing. Placing the client in a high Fowler's position immediately reduces venous return and eases breathing. Oxygen is applied next to treat hypoxia. Once ABCs are stabilized, baseline vital signs must be taken to safely administer medications. Intravenous furosemide is then given to pull fluid from the lungs, followed by the insertion of a urinary catheter to closely monitor the diuresis.

A nurse is caring for a client who is receiving continuous total parenteral nutrition (TPN) through a dedicated lumen of a multi-lumen central venous catheter (CVC). The healthcare provider prescribes a scheduled dose of an intravenous (IV) antibiotic. Which of the following actions is the most appropriate for the nurse to take when administering the medication?

Cevabı ve açıklamayı göster

Cevap: Administer the antibiotic through an alternate, available lumen of the central venous catheter.

Cevap

The nurse should administer the antibiotic through an alternate, available lumen of the central venous catheter.
Total parenteral nutrition (TPN) solutions have a very high glucose and nutrient concentration, making them highly susceptible to both chemical incompatibility and bacterial contamination. Consequently, standard nursing practice mandates that TPN must be infused through a strictly dedicated line or a dedicated lumen of a multi-lumen catheter. Because the client has a multi-lumen central venous catheter, the nurse can safely administer the antibiotic through a separate, available lumen. The separate lumens allow incompatible fluids to enter the central bloodstream independently, where high blood flow instantly dilutes them.

Adım Adım Çözüm

1
Assess the current intravenous access and the prescribed therapies.
The client has a multi-lumen central venous catheter with one lumen dedicated to TPN, and requires IV antibiotic administration.
Understanding the available access determines the safest route for new intravenous medications without compromising existing infusions.
2
Identify the safety principles regarding TPN administration.
TPN must always run through a strictly dedicated line or lumen to prevent precipitation, chemical incompatibility, and infection.
The hypertonic, complex nature of TPN makes it highly reactive with other medications.
3
Select the intervention that preserves the dedicated TPN line while safely delivering the antibiotic.
Utilizing a separate, available lumen on the existing multi-lumen catheter achieves both goals.
Multi-lumen catheters are designed to infuse incompatible solutions simultaneously, as the lumens exit at different points in the high-flow central venous system.

Cevap

The correct sequence is to preoxygenate, insert without suction, withdraw slightly, apply suction while rotating outward, and finally reassess.
To reduce the risk of life-threatening complications such as hypoxemia, cardiac dysrhythmias, and mucosal trauma, the nurse must adhere to a strict procedural sequence. Preoxygenation provides a critical oxygen reserve. Inserting the catheter without suction protects the airway lining. Withdrawing the catheter slightly before applying suction prevents adherence to the carina, avoiding vagal stimulation. Applying suction only during withdrawal with a rotating motion safely removes secretions. Reassessing the client verifies the procedure's success and the client's stability.

Adım Adım Çözüm

1
Preoxygenate the client.
Increases the client's arterial oxygenation levels.
Prevents hypoxemia during the procedure.
2
Insert the catheter without applying suction.
The catheter reaches the level of the carina or mainstem bronchi.
Applying suction during insertion causes severe tissue trauma and oxygen depletion.
3
Withdraw the catheter 1 to 2 centimeters.
The catheter tip is moved away from the sensitive carina.
Prevents direct vagal stimulation and localized tissue damage when suction is applied.
4
Apply intermittent suction while rotating and withdrawing.
Secretions are safely cleared from the airway.
Rotation prevents the catheter tip from continuously adhering to one area of the tracheal mucosa.
5

Cevabı ve açıklamayı göster

Cevap: Initiate rapid infusion of intravenous isotonic crystalloid fluids.

Cevap

The priority action is to initiate a rapid infusion of intravenous isotonic crystalloid fluids.
The client is exhibiting classic signs of the compensatory stage of hypovolemic shock, likely due to internal hemorrhage from the abdominal trauma. As blood volume drops, the sympathetic nervous system triggers an increased heart rate to maintain cardiac output and peripheral vasoconstriction, which raises the diastolic blood pressure and narrows the pulse pressure. The most critical intervention is to aggressively restore intravascular volume with isotonic crystalloids.

Adım Adım Çözüm

1
Analyze the vital sign trends.
The heart rate increased significantly (86 to 116 bpm) while the pulse pressure narrowed dramatically (from 48 mm Hg to 22 mm Hg).
Identifying changes in vital signs over time is critical for detecting physiological deterioration before profound hypotension occurs.
2
Correlate the findings with the mechanism of injury.
Blunt abdominal trauma combined with tachycardia and a narrowing pulse pressure indicates compensatory hypovolemic shock (internal bleeding).
The body compensates for lost circulating volume by increasing the heart rate and vasoconstricting, which raises the diastolic blood pressure and narrows the pulse pressure.
3
Determine the priority nursing intervention.
Fluid resuscitation with isotonic crystalloids is required immediately.
In hypovolemic shock, restoring intravascular volume is the primary intervention to maintain cardiac output and tissue perfusion.

Cevap: The client reports a new onset of dull, aching pain in the lower back and right flank.

Cevap

The client reports a new onset of dull, aching pain in the lower back and right flank.
Following a cardiac catheterization via the femoral artery, bleeding can occur internally into the retroperitoneal space. Because this space can hold a large volume of blood without obvious external swelling, the earliest clinical indicator is often a new onset of dull, aching pain in the lower back or flank on the operative side. This finding requires immediate intervention, such as applying manual pressure and notifying the healthcare provider, to reduce the risk of profound hypovolemic shock.

Adım Adım Çözüm

1
Analyze the procedure and its associated risks.
Cardiac catheterization via the femoral artery carries a high risk of bleeding, specifically retroperitoneal hemorrhage, which can be life-threatening.
Identifying the highest risk complication guides the post-procedure assessment priorities.
2
Evaluate each assessment finding against expected versus abnormal post-procedure outcomes.
Positioning, minor ecchymosis, and slight blood pressure changes are expected. Flank or lower back pain is an abnormal, critical finding.
Differentiating expected physiological findings from abnormal findings is required to identify clinical deterioration.

Cevap: Position the head of the bed at a 60- to 90-degree angle; Apply supplemental oxygen using a high-flow delivery device; Notify the facility's rapid response or emergency medical team

Cevap

The correct actions involve elevating the head of the bed, applying supplemental oxygen immediately, and activating the rapid response team.
The client is exhibiting classic signs of an acute pulmonary embolism, a life-threatening medical emergency commonly associated with immobility following major orthopedic surgery. Immediate nursing priorities must focus on optimizing oxygenation and ventilation. Elevating the head of the bed maximizes diaphragmatic excursion and lung expansion. Applying high-flow oxygen directly addresses the severe hypoxia. Because the client is rapidly decompensating and unstable, activating the rapid response team is a critical simultaneous action to secure advanced airway management and initiate hemodynamic support or anticoagulation.

Upon evaluating a client recovering from an extensive small bowel resection, the assigned nurse notes a scheduled order for intravenous pantoprazole. The client's only vascular access is a single-lumen peripherally inserted central catheter (PICC) that is currently delivering total parenteral nutrition (TPN) at 90 mL/hr. How should the nurse proceed with administering the prescribed gastrointestinal protectant?

Cevabı ve açıklamayı göster

Cevap: Establish a new peripheral intravenous access site specifically for the medication administration.

Cevap

The nurse must establish a new peripheral intravenous access site specifically for the medication administration.
Total parenteral nutrition (TPN) is a complex, hypertonic solution that carries an exceptionally high risk for microbial growth and chemical incompatibility when mixed with other pharmacological substances. Evidence-based nursing practice dictates that TPN must be administered through a strictly dedicated intravenous line. Because the client only has a single-lumen PICC currently infusing TPN, the nurse must establish a new, separate peripheral IV line to safely administer the prescribed medication without interrupting the continuous nutritional support or risking precipitation within the central line.

Adım Adım Çözüm

1
Analyze the client's current vascular access and active infusions.
The client possesses a single-lumen PICC that is entirely dedicated to a continuous TPN infusion.
Identifying existing access determines whether a new medication can be administered safely through the current line or if alternative access is necessary.
2
Evaluate the safety principles and protocols regarding total parenteral nutrition (TPN).
TPN requires a strictly dedicated line; it cannot be paused for other medications, nor can medications be piggybacked into its tubing.
TPN solutions are complex, highly concentrated mixtures that are prone to chemical incompatibilities. Furthermore, frequently accessing the line significantly increases the risk of dangerous bloodstream infections.
3
Determine the most appropriate and safe nursing intervention for the scheduled medication.
A new peripheral IV catheter must be inserted by a qualified healthcare professional (the RN) to administer the pantoprazole.
This action ensures the scheduled medication is delivered on time while simultaneously preserving the integrity, safety, and continuous flow of the TPN line.

Cevap: The client's heart rate has trended upward from 7676 to 114114 beats per minute over the last 3030 minutes.; The client reports a new onset of sharp pain radiating to the right shoulder.; The client exhibits asymmetrical chest expansion and diminished breath sounds on the right side.

Cevap

The findings that require immediate intervention are the upward trend in heart rate, the new sharp pain radiating to the right shoulder, and the asymmetrical chest expansion.
Following a percutaneous liver biopsy, the client is at significant risk for severe complications such as hemorrhage, bile peritonitis, and pneumothorax. An increasing heart rate is a subtle but critical early indicator of hypovolemic shock caused by internal bleeding. New onset of sharp pain radiating to the right shoulder is referred pain that strongly suggests diaphragmatic irritation from accumulating blood or bile. Furthermore, asymmetrical chest expansion with diminished breath sounds on the right side indicates a pneumothorax, which can occur if the pleural cavity was inadvertently punctured during the biopsy. All three of these findings indicate acute physiological decompensation and require immediate life-saving nursing and medical interventions.

The client is 11 hour post-percutaneous liver biopsy, a highly vascular organ located near the pleural cavity.
Identifying the specific procedure helps anticipate the most severe physiological risks, namely hemorrhage, bile leak, and pneumothorax.
2
Evaluate each option for signs of physiological decompensation.
Tachycardia indicates potential shock, right shoulder pain indicates diaphragmatic irritation (bleeding/bile leak), and asymmetrical chest expansion indicates pneumothorax.
Early recognition of shock, peritonitis, or respiratory compromise allows for rapid medical intervention to reduce morbidity.
3
Differentiate between life-threatening abnormalities and expected post-procedure outcomes.
Right-side positioning, normal arterial blood gases, and mild localized soreness are either expected outcomes or therapeutic interventions.
Distinguishing normal from abnormal prevents unnecessary interventions and correctly prioritizes life-saving care.

Cevap

1. Stop the blood transfusion.
2. Disconnect the blood tubing and initiate an infusion of normal saline using new tubing.
3. Assess the client's vital signs and respiratory status.
4. Notify the healthcare provider and the blood bank.
5. Send the remaining blood product and tubing to the blood bank for analysis.
In the event of a suspected acute hemolytic blood transfusion reaction, the absolute first priority is to stop the infusion to prevent further exposure to the incompatible antigen. Once the infusion is stopped, the nurse must maintain a patent IV line for emergency medications by infusing 0.9% sodium chloride using completely new tubing (to avoid pushing residual blood into the client). Next, the nurse performs a rapid physical assessment, including vital signs and respiratory status, to evaluate the severity of the physiological compromise. The nurse then notifies the healthcare provider to obtain emergency prescriptions and alerts the blood bank. Finally, the remaining blood, tubing, and labels are sent back to the blood bank for crossmatching and post-reaction analysis.

Adım Adım Çözüm

1
Identify the complication occurring in the clinical scenario.
The client is experiencing a severe acute hemolytic transfusion reaction.
Lower back pain, chills, hypotension, and tachycardia shortly after starting a transfusion are hallmark physiological signs of an acute hemolytic reaction.
2
Determine the absolute first priority action.
Stop the blood transfusion.
The immediate priority in any adverse medication or blood reaction is to remove the causative agent to limit further physiological damage.
3
Determine the next action required to safely maintain venous access.
Disconnect the existing tubing and initiate normal saline using new tubing.
Venous access must be maintained for emergency interventions, but flushing the existing blood tubing would push more incompatible blood into the client.
4
Determine the next action to evaluate the client's condition.
Assess vital signs and respiratory status.
A rapid physiological assessment is necessary to determine the severity of the reaction and to prepare a complete, accurate report for the healthcare provider.
5
Determine the appropriate notification and follow-up protocol steps.
Notify the provider and blood bank, then send the remaining product to the laboratory.
The provider must prescribe emergency pharmacological interventions, and the blood bank must analyze the remaining product and tubing to confirm the reaction etiology.

Cevap: Verifying a client's baseline activated partial thromboplastin time (aPTT) and platelet count before initiating a continuous intravenous (IV) heparin infusion.; Hanging an infusion of 10% dextrose in water (D10W) at the same rate when a client's next scheduled bag of total parenteral nutrition (TPN) is temporarily delayed.

Cevap

The correct actions are verifying the aPTT and platelet count prior to initiating heparin, and hanging 10% dextrose in water (D10W) when a TPN bag is delayed.
Verifying baseline coagulation values before starting heparin is essential to monitor for therapeutic effect and adverse reactions like heparin-induced thrombocytopenia. Additionally, hanging D10W when TPN is delayed is a standard safety protocol to prevent rebound hypoglycemia caused by the sudden withdrawal of a high-glucose continuous infusion.

Adım Adım Çözüm

1
Evaluate the heparin administration action.
Safe practice identified.
Baseline coagulation studies (aPTT, platelets) must be documented before starting systemic anticoagulation to establish a reference point and ensure there are no pre-existing bleeding risks.
2
Calculate the correct insulin pump rate.
Unsafe practice identified.
A concentration of 100 units in 100 mL equates to 1 unit/mL. To deliver 5 units/hr, the pump must be set to 5 mL/hr, not 50 mL/hr. The described action causes a severe overdose.
3
Assess the phenytoin administration.
Unsafe practice identified.
Phenytoin is chemically incompatible with dextrose solutions and will precipitate. It must only be mixed or flushed with normal saline.
4
Evaluate the TPN substitution action.
Safe practice identified.
If TPN is abruptly stopped, substituting with D10W at the same rate prevents profound rebound hypoglycemia.
5
Determine the priority of care.
Unsafe prioritization identified.
An alarming pump for a critical vasoactive medication (nitroglycerin) takes precedence over mild peripheral site pruritus.

Anahtar Kavram

Safe parenteral therapy requires accurate dosage calculations, verification of IV fluid compatibility, proactive complication management (such as preventing hypoglycemia with TPN), and appropriate prioritization of critical medication infusions.

A client with a mechanical small bowel obstruction has been on low continuous nasogastric (NG) wall suction for the past 4848 hours. The client begins to report numbness and tingling around the mouth and muscle cramping in the calves. Morning arterial blood gas (ABG) results are: pH 7.517.51, PaCO 2_2 4343 mm Hg, HCO 3−_3^- 3232 mEq/L. To reduce the risk of a severe complication associated with these findings, which focused assessment should the nurse perform next?

Cevap: Analyze the client's electrocardiogram (ECG) rhythm strip for prominent U waves or ST depression.

Cevap

Analyze the client's electrocardiogram (ECG) rhythm strip for prominent U waves or ST depression.
The correct answer addresses the most severe physiological threat stemming from the client's current status. The ABG indicates metabolic alkalosis, a direct result of gastric acid loss from NG suction. In metabolic alkalosis, potassium shifts into the cells, leading to hypokalemia. Simultaneously, calcium binds more readily to albumin, resulting in decreased ionized calcium, which causes the tetany (numbness, tingling, cramping) the client reports. The most life-threatening complication of hypokalemia is the development of cardiac dysrhythmias. The nurse must prioritize analyzing the ECG for classic signs of hypokalemia, such as prominent U waves and ST depression, to mitigate this severe risk.

Adım Adım Çözüm

1
Interpret the provided arterial blood gas (ABG) values.
The pH of 7.517.51 indicates alkalosis, and the HCO 3−_3^- of 3232 mEq/L indicates a metabolic primary cause. The PaCO 2_2 is normal, indicating an uncompensated state.
Identifying the exact acid-base imbalance is the first step in anticipating the client's physiological complications.
2
Correlate the acid-base imbalance with the clinical scenario.
Prolonged nasogastric suction removes hydrochloric acid from the stomach, which is the direct cause of the metabolic alkalosis.
Understanding the etiology helps anticipate the associated secondary electrolyte shifts.
3
Identify the electrolyte derangements associated with metabolic alkalosis.
Metabolic alkalosis triggers an intracellular shift of potassium, causing hypokalemia. It also increases calcium binding to albumin, decreasing ionized calcium and causing tetany (manifested as numbness and cramping).
Electrolyte imbalances drive the most immediate and life-threatening complications.
4
Determine the highest-priority nursing assessment to reduce the risk of a severe complication.
Hypokalemia severely destabilizes cardiac conduction, risking lethal dysrhythmias. Assessing the ECG for hypokalemic indicators (U waves, ST depression) is the most critical intervention.
Cardiac dysrhythmias pose the most immediate threat to the client's life and require rapid identification.
