Show answer & explanation

Answer: Administer the stat IV furosemide through Lumen 2 after flushing the port with $0.9\%$ sodium chloride.; Verify the physical compatibility of the continuous heparin infusion with $0.9\%$ sodium chloride before connecting it to Lumen 2.; Evaluate the client's continuous electrocardiogram (ECG) rhythm and baseline serum creatinine prior to initiating the potassium chloride.

Answer

The nurse should administer the furosemide through Lumen 2 after flushing, verify the compatibility of heparin with the normal saline in Lumen 2, and evaluate the ECG rhythm and renal function before giving the potassium chloride.

Safe central line management and pharmacology principles require the nurse to protect dedicated lines for vasoactive infusions, thoroughly verify fluid compatibility before Y-site administration, flush lines adequately between intermittent medications, and apply rigorous monitoring and rate limits to high-alert electrolytes like potassium chloride.

Step-by-Step Solution

Analyze the critical nature of the existing infusions.

Identify that dobutamine (Lumen 1) is a life-sustaining vasoactive medication that cannot be paused or interrupted.

Maintaining hemodynamic stability is the highest priority in decompensated heart failure.

Evaluate compatibility constraints for the new prescriptions.

Determine that heparin and dobutamine are incompatible, so heparin cannot be infused via Lumen 1.

Mixing incompatible medications causes precipitation, risking embolism and altered drug efficacy.

Plan safe administration parameters for high-alert medications.

Recognize that IV potassium chloride requires strict rate limits (max

20\text{ mEq/hr}

centrally) and pre-assessment of renal and cardiac status.

Rapid or unmonitored potassium administration can cause fatal cardiac arrhythmias.

Key Concept

Safe administration of parenteral therapies requires continuous maintenance of critical inotropes, strict verification of IV compatibility, and adherence to high-alert medication administration parameters.

Show answer & explanation

Answer: Maintain the right leg in a straight position while log-rolling the client to the left side for back care.; Instruct the client in deep breathing and guided imagery to help manage the back discomfort.; Apply a protective moisture barrier ointment to the sacral area after cleansing the skin.

Answer

The appropriate interventions include keeping the right leg straight while log-rolling to the left side, teaching relaxation techniques for comfort, and applying barrier cream to the sacrum.

Appropriate basic care for a client post-femoral catheterization involves adapting hygiene and comfort measures to strict positioning limits. The client must be log-rolled to the unaffected side while keeping the affected limb straight to prevent bleeding. Providing non-pharmacologic comfort and applying skin barrier cream are essential, safe nursing actions that maintain physiological integrity during bed rest.

Step-by-Step Solution

Analyze the client's current clinical constraints

The client has a right femoral artery puncture site, requiring strict bed rest with the right leg kept completely straight and the head of the bed elevated no more than 30 degrees.

To prevent bleeding or hematoma formation at the high-pressure arterial access site.

Evaluate hygiene interventions

Hygiene can be safely provided by log-rolling the client to the left (unaffected) side while ensuring the right leg remains extended. Barrier cream should be applied to protect the sacral skin from breakdown.

Basic care must be adapted to align with post-procedure mobility restrictions.

Evaluate pain management and assessment interventions

Non-pharmacologic methods like deep breathing should be used for comfort. The RN must personally assess the back pain instead of delegating it, as it could indicate a complication.

Pain assessment requires clinical judgment, especially to rule out retroperitoneal hemorrhage.

Question 1123Question →

A nurse is caring for a 68-year-old client with symptomatic anemia (hemoglobin 6.8 g/dL) who is prescribed a packed red blood cell (PRBC) transfusion. To reduce the risk of adverse reactions and ensure safe administration, place the following steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is to first verify the prescription and consent, then assess IV patency and baseline vital signs, retrieve the blood from the blood bank, perform the two-nurse bedside verification, and finally initiate the transfusion while monitoring the client closely for the first 15 minutes.

Safe administration of blood products requires a strict chronological sequence to minimize the risk of complications such as transfusion reactions or product waste. The nurse must first ensure a valid prescription and consent exist. Second, assessing IV patency and vital signs ensures the client is physiologically ready to receive the blood, preventing product waste if the IV needs restarting. Third, the blood is retrieved from the blood bank, as it must be initiated within 30 minutes. Fourth, two-nurse bedside verification prevents fatal ABO incompatibility errors. Finally, the transfusion is started slowly, with the nurse remaining present for the first 15 minutes to monitor for any acute life-threatening reactions.

Step-by-Step Solution

Verify prescription and consent.

Ensures legal authorization to proceed.

Blood administration requires explicit provider orders and informed client consent due to the inherent physiological risks.

Assess IV patency and baseline vital signs.

Confirms physical readiness for the transfusion.

Prevents blood product waste if IV access is compromised or if baseline vital signs indicate a contraindication to starting the transfusion (e.g., a high fever).

Retrieve blood from the blood bank.

Obtains the necessary blood product.

Blood must be initiated within 30 minutes of leaving the temperature-controlled blood bank environment to prevent bacterial growth and RBC degradation.

Perform two-nurse bedside verification.

Confirms the correct product is given to the correct client.

Independent double-checking at the bedside is the primary method to prevent ABO incompatibility and acute hemolytic transfusion reactions.

Initiate slowly and monitor for 15 minutes.

Detects early signs of adverse physiological reactions.

Question 1124Question →

A nurse in the intensive care unit is caring for a client who weighs $187\text{ lbs}$ and is receiving a continuous intravenous infusion of norepinephrine for septic shock. The medication is supplied as $4\text{ mg}$ of norepinephrine in $250\text{ mL}$ of $5\%$ dextrose in water ( $D_5W$ ). The infusion is currently running at $17\text{ mL/hr}$ .

The client's current vital signs include a heart rate of $112\text{ bpm}$ and a blood pressure of $82/46\text{ mmHg}$ (mean arterial pressure [MAP] $58\text{ mmHg}$ ).

The provider's prescribed titration parameters state: "Titrate norepinephrine infusion by $0.02\text{ mcg/kg/min}$ every 5 minutes to maintain a MAP $\geq 65\text{ mmHg}$ ."

Based on the client's current MAP, the nurse performs one titration increase. What should the nurse set the new infusion pump rate to in $\text{mL/hr}$ ? (Record answer to the nearest tenth.)

Show answer & explanation

Answer: 23.4

Answer

The new infusion pump rate should be set to 23.4 mL/hr.

The client's mean arterial pressure (MAP) is

58\text{ mmHg}

(

[82 + 2(46)] \div 3

), indicating the need to titrate the norepinephrine upward per the provider's parameters (MAP less than

65\text{ mmHg}

). First, the weight is converted to

85\text{ kg}

(

187 \div 2.2

). The ordered increase is

0.02\text{ mcg/kg/min}

, which equals an additional

1.7\text{ mcg/min}

(

0.02 \times 85

) or

102\text{ mcg/hr}

(

1.7 \times 60

). The concentration of the IV bag is

16\text{ mcg/mL}

(

4,000\text{ mcg} \div 250\text{ mL}

). The required increase in fluid volume is

6.375\text{ mL/hr}

(

102 \div 16

). Adding this to the baseline rate of

17\text{ mL/hr}

yields

23.375\text{ mL/hr}

. Rounding to the nearest tenth provides the final correct rate of

23.4\text{ mL/hr}

Step-by-Step Solution

Assess the clinical situation to determine the necessary intervention.

The client's MAP is

58\text{ mmHg}

, which is below the target of

\geq 65\text{ mmHg}

. Therefore, a titration increase of

0.02\text{ mcg/kg/min}

is required.

Vasopressor infusions must be titrated according to prescribed parameters based on objective hemodynamic data.

Convert the client's weight from pounds to kilograms.

187\text{ lbs} \div 2.2\text{ lbs/kg} = 85\text{ kg}

Critical care medication dosing parameters are strictly weight-based in kilograms.

Calculate the concentration of the norepinephrine solution in

\text{mcg/mL}

4\text{ mg} = 4,000\text{ mcg}

. Then,

4,000\text{ mcg} \div 250\text{ mL} = 16\text{ mcg/mL}

You must know the concentration of the fluid in micrograms to calculate the volume needed.

Calculate the required titration dose increase per minute based on the client's weight.

0.02\text{ mcg/kg/min} \times 85\text{ kg} = 1.7\text{ mcg/min}

This establishes the exact additional amount of medication the client needs every minute.

Convert the per-minute dose increase to an hourly rate.

1.7\text{ mcg/min} \times 60\text{ min/hr} = 102\text{ mcg/hr}

IV pumps are programmed in

\text{mL/hr}

, so the medication dose must be converted to an hourly metric.

Determine the volume of fluid per hour required to deliver the dose increase.

102\text{ mcg/hr} \div 16\text{ mcg/mL} = 6.375\text{ mL/hr}

Dividing the hourly dose by the concentration yields the physical volume increase.

Calculate the new total infusion rate.

17\text{ mL/hr} + 6.375\text{ mL/hr} = 23.375\text{ mL/hr}

The calculated delta must be added to the baseline continuous rate to achieve the new prescribed dose.

Round the final calculated rate to the requested decimal place.

23.375

rounds to

23.4\text{ mL/hr}

Standard rounding rules apply; because the hundredths digit is 7, round the tenths digit up.

Question 1125Question →

A nurse is preparing to transfer a client who is 2 days postoperative following a right total hip arthroplasty (posterior approach) from the bed to a bedside chair. In what order should the nurse perform the following actions? (Arrange the steps in the correct sequential order)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Place the chair on the left side, help the client sit on the bed edge with the right leg extended, apply the transfer belt, stand bearing weight on the left leg while extending the right leg, and pivot on the left foot to sit in the chair.

The sequence follows the standard principles of safe patient handling combined with strict posterior total hip arthroplasty precautions. First, the environment is prepared by placing the chair on the client's unaffected (left) side. Second, the client is assisted to sit on the edge of the bed while the operative (right) leg is kept extended to prevent hip flexion greater than 90 degrees. Third, a transfer belt is applied for safety. Fourth, the client stands, bearing weight on the strong left leg while continuing to keep the right leg extended. Finally, the client pivots on the strong left leg, reaches back for the chair, and sits down while maintaining the operative leg in extension to prevent dislocation.

Step-by-Step Solution

Place the bedside chair at a 45-degree angle on the client's left side and lock the wheels.

The environment is prepared for a safe transfer toward the strong side.

Transfers should always move toward the client's unaffected (strong) side. Environmental safety must be secured before moving the client.

Help the client to a sitting position on the edge of the bed while maintaining the right leg in an extended position.

The client is positioned at the edge of the bed without violating hip precautions.

Keeping the operative (right) leg extended prevents the hip from flexing beyond 90 degrees, which could cause dislocation in a posterior approach arthroplasty.

Secure a transfer belt snugly around the client's waist over their clothing.

The nurse has a safe, ergonomic method to assist the client during the weight-bearing phase.

The transfer belt is applied once the client is sitting to ensure a snug fit and safe grasping point before the client attempts to stand.

Instruct the client to bear weight primarily on the left leg and stand while keeping the right leg extended.

The client achieves a standing position safely.

Bearing weight on the unaffected (left) leg protects the surgical site. Extending the right leg forward prevents excessive hip flexion during the transition from sitting to standing.

Assist the client to pivot on the left foot and reach back for the chair armrests.

The client safely completes the transfer and sits in the chair.

Pivoting on the strong leg avoids twisting the operative hip. Reaching back for the armrests allows for a controlled descent, maintaining the right leg in extension to avoid breaking the 90-degree flexion rule.

Question 1126Question →

A nurse is caring for a client with community-acquired pneumonia who has a continuous primary intravenous (IV) infusion of 0.9% sodium chloride running at 75 mL/hr. The healthcare provider prescribes an intermittent dose of IV ceftriaxone to infuse over 30 minutes. Arrange the following steps in the correct order for safely setting up and initiating the secondary infusion using a gravity drip system.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with verifying fluid compatibility, followed by priming the secondary tubing, scrubbing the primary line access port, connecting the tubing and lowering the primary bag, and finally regulating the drip rate.

Safe administration of a secondary IV piggyback medication via a gravity system requires a logical sequence that prevents patient harm. Verification of fluid compatibility is the absolute first step. Next, the secondary tubing is primed with the medication to prevent air embolism. Infection control follows, requiring the nurse to vigorously scrub the upper needleless access port before any connection is made. Connecting the tubing and utilizing an extension hook to lower the primary bag utilizes gravity to prioritize the secondary infusion over the primary fluid. Finally, regulating the drip rate ensures accurate and safe dosing over the prescribed time frame.

Step-by-Step Solution

Verify the compatibility of the IV ceftriaxone with the continuous primary infusion of 0.9% sodium chloride.

The nurse confirms that the two fluids will not precipitate or interact adversely.

Safety must be established first; incompatible fluids can cause crystallization in the IV line, leading to a blocked catheter or embolus.

Spike the ceftriaxone bag and prime the secondary intravenous tubing.

The secondary IV line is filled with medication and is completely free of air bubbles.

Air must be purged from the secondary tubing before attaching it to the primary system to prevent a life-threatening air embolism.

Scrub the needleless access port on the primary tubing located above the roller clamp.

The access port is properly disinfected.

Vigorous scrubbing with an antimicrobial swab maintains infection control and prevents the introduction of microorganisms into the patient's circulatory system.

Connect the secondary tubing to the primary line and hang the primary fluid bag lower than the ceftriaxone bag.

The secondary line is successfully integrated, and a proper gravity gradient is established.

In a gravity drip system, the secondary bag must be hung physically higher than the primary bag so hydrostatic pressure allows the secondary medication to infuse first.

Open the secondary roller clamp and adjust the flow rate to the prescribed drops per minute.

The secondary medication begins infusing at the correct therapeutic speed.

Proper flow rate regulation ensures the patient receives the antibiotic safely over the prescribed 30 minutes without causing speed shock or fluid overload.

Key Concept

The correct procedural sequence for administering a secondary IV piggyback (IVPB) infusion prioritizes chemical compatibility, stringent infection control, and the physical principles of hydrostatic pressure in a gravity system.

A nurse is developing a plan of care to maintain skin integrity and provide comfort for an older adult client who is immobile. Which of the following interventions is the most appropriate for the nurse to include?

Maintain the head of the bed elevated at 90 degrees for extended periods to promote comfort.

Delegate the initial assessment of the client's skin breakdown risk to the unlicensed assistive personnel.

Use a draw sheet or friction-reducing device to lift the client when changing their position in bed.

Assume the client's sudden onset of urinary incontinence is a normal age-related change and solely apply absorbent briefs.

Show answer & explanation

Answer: Use a draw sheet or friction-reducing device to lift the client when changing their position in bed.

Answer

The most appropriate intervention is to use a draw sheet or friction-reducing device to lift the client when changing their position in bed.

Using a draw sheet or a friction-reducing device allows the nurse to lift rather than drag the client across the bed linens. This intervention directly prevents friction and shearing forces, which are primary contributors to skin breakdown and pressure injuries in immobile older adults.

Step-by-Step Solution

Identify the client's primary needs based on the clinical scenario.

The client is an immobile older adult, which places them at high risk for friction, shear, and pressure injuries.

Understanding the physiological risks associated with immobility guides the selection of protective care measures.

Evaluate the safety and physiological impact of each proposed intervention.

Lifting with a draw sheet prevents shear. Conversely, prolonged 90-degree head elevation increases shear. Delegating an initial assessment violates scope of practice. Dismissing sudden incontinence ignores potential pathology.

Basic care interventions must align with evidence-based standards for safe positioning, proper delegation, and accurate clinical judgment.

Select the nursing action that safely promotes comfort and skin integrity.

Using a draw sheet or friction-reducing device is identified as the correct action.

It actively protects the client's skin from mechanical damage during necessary repositioning.

Question 1129Question →

Two hours following a diagnostic lumbar puncture, a client reports intense hunger and requests the lunch tray that was just delivered. The provider has prescribed strict flat bed rest for six hours. Which action is the most appropriate for the nurse to take?

Elevate the head of the bed to 30 degrees for 20 minutes while the client consumes the meal.

Assist the client with eating while they remain strictly in a flat, supine position.

Log-roll the client into a lateral position while maintaining a flat spinal alignment to assist with the meal.

Instruct the unlicensed assistive personnel (UAP) to feed the client and monitor for signs of aspiration.

Show answer & explanation

Answer: Log-roll the client into a lateral position while maintaining a flat spinal alignment to assist with the meal.

Answer

Log-roll the client into a lateral position while maintaining a flat spinal alignment to assist with the meal.

After a lumbar puncture, clients must remain flat (zero-degree elevation) for several hours to prevent cerebrospinal fluid (CSF) from leaking at the puncture site, which can cause a severe post-dural puncture headache. However, eating while flat and supine poses a critical aspiration risk. The safest nursing intervention is to log-roll the client into a lateral (side-lying) position. This maintains the required flat spinal alignment to protect the dural puncture site while utilizing gravity to clear the airway and facilitate safer swallowing, thus addressing both safety constraints simultaneously.

Step-by-Step Solution

Analyze the client's current procedural restrictions based on the recent intervention.

The client had a lumbar puncture and is prescribed strict flat bed rest to prevent a cerebrospinal fluid (CSF) leak.

Hydrostatic pressure on the dural puncture site increases when the head is elevated above the spine, which can cause a severe spinal headache.

Evaluate the competing physiological need and its associated risks.

The client is hungry and needs to eat, which introduces a severe aspiration risk if oral intake occurs while lying flat in a supine position.

Swallowing against gravity in a supine position impairs airway protection.

Synthesize a nursing intervention that safely addresses both the procedural constraint and the physiological need.

Positioning the client in a lateral (side-lying) position without head elevation maintains the required flat spinal alignment while facilitating safer swallowing.

The lateral position keeps the dural puncture site protected at zero degrees of elevation while using gravity to keep the airway clear of pooled food or liquids.

A nurse is providing care for an older adult client who has just returned to the unit following a diagnostic lumbar puncture. The client reports a headache, and family members express concern that the client is suddenly exhibiting mild confusion. Which of the following is the most appropriate nursing action?

Elevate the head of the bed to 45 degrees to help alleviate the client's headache.

Document the sudden confusion as an expected physiological change of the aging process.

Maintain the client in a flat, supine position for the prescribed duration.

Delegate the initial evaluation of the lumbar puncture dressing to the unlicensed assistive personnel.

Show answer & explanation

Answer: Maintain the client in a flat, supine position for the prescribed duration.

Answer

The most appropriate action is to maintain the client in a flat, supine position for the prescribed duration to prevent or manage a post-dural puncture headache.

Following a lumbar puncture, cerebrospinal fluid (CSF) can leak from the dural puncture site, leading to decreased intracranial pressure and a severe post-dural puncture (spinal) headache. Maintaining the client in a flat, supine (or prone) position for a prescribed period—typically 4 to 8 hours—minimizes this fluid leakage. This promotes comfort, stabilizes CSF pressure, and is a foundational basic care intervention following this specific procedure.

Step-by-Step Solution

Analyze the physiological risks associated with the recent procedure.

The client has undergone a lumbar puncture, which carries a primary risk of cerebrospinal fluid (CSF) leakage leading to a severe spinal headache.

Understanding the procedure dictates the necessary positioning interventions for patient comfort and safety.

Evaluate the significance of the new onset of confusion.

Sudden confusion is identified as an acute change in mental status, not a normal aspect of aging.

Acute neurological changes require prompt assessment by the registered nurse to rule out serious complications.

Determine the appropriate delegation of post-procedure care.

Assessing the puncture site for bleeding or hematoma formation must be done by the RN and cannot be delegated.

Initial evaluations require professional nursing judgment, which is outside the unlicensed assistive personnel's scope of practice.

Select the safest and most effective nursing intervention from the available choices.

Maintaining a flat, supine position is chosen as the correct intervention.

Lying flat minimizes CSF pressure at the puncture site, directly addressing the client's risk for a worsening post-procedure headache.

Encourage the client to ambulate around the room to promote circulation.

Show answer & explanation

Answer: Maintain the client in a flat, supine position for several hours.

Answer

The nurse should maintain the client in a flat, supine position for several hours.

Maintaining a flat, supine position for several hours minimizes the hydrostatic pressure of cerebrospinal fluid at the lumbar puncture site. This prevents CSF leakage, which is the underlying cause of a post-dural puncture headache.

Step-by-Step Solution

Identify the primary complication associated with a lumbar puncture.

The most common complication is a post-dural puncture headache, caused by the leakage of cerebrospinal fluid (CSF) from the puncture site.

Understanding the pathophysiology of the complication dictates the appropriate nursing intervention.

Determine the optimal intervention to prevent this complication.

Keeping the client flat and supine minimizes hydrostatic pressure on the dura mater.

Reduced pressure allows the puncture site to heal and prevents further CSF leakage.

Delegate the continuous monitoring of vital signs to the unlicensed assistive personnel.

Show answer & explanation

Answer: Notify the healthcare provider immediately and prepare to administer intravenous fluids.

Answer

Notify the healthcare provider immediately and prepare to administer intravenous fluids.

The correct answer identifies that the client is experiencing a retroperitoneal hemorrhage. Tachycardia, hypotension, and severe lower back pain after a femoral catheterization are hallmark signs of this concealed bleeding. Immediate notification of the provider and preparation for fluid resuscitation are critical risk reduction measures to prevent severe shock.

Step-by-Step Solution

Analyze the client's clinical presentation and vital sign trends.

The client has new-onset severe back pain, tachycardia, and hypotension four hours after a femoral arterial procedure.

Identifying acute changes from baseline is essential for early complication detection.

Correlate the clinical findings with potential procedural complications.

The combination of symptoms strongly indicates a retroperitoneal hemorrhage, despite a dry external dressing.

Blood from the femoral artery can leak backward into the retroperitoneal space, causing flank or back pain and concealed hypovolemia.

Determine the priority nursing intervention.

The nurse must immediately alert the healthcare provider and prepare to restore intravascular volume.

Rapid medical intervention and fluid resuscitation are required to mitigate the risk of severe hemorrhagic shock and potential cardiovascular collapse.

Key Concept

Question 1133Question →

Prior to an endoscopic procedure, a client requires the administration of a large-volume cleansing enema. The supplies are at the bedside, and the client's identity has been verified. In what sequence should the nurse perform the administration steps? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first position the client in the left lateral Sims position, then place a protective pad and don gloves, lubricate the tip of the enema tubing, safely insert the tube into the rectum, and finally release the clamp while elevating the container to the correct height.

Safe enema administration requires following a logical sequence that prioritizes anatomical alignment, infection control, and trauma prevention. Positioning the client properly on the left side ensures gravity assists the fluid. Once positioned, the nurse ensures hygiene and lubricates the tubing to protect the mucosa. After safely inserting the tube following the bowel's anatomical curve, the nurse initiates the fluid flow at a controlled height to prevent sudden cramping and maximize retention.

Step-by-Step Solution

Assist the client into the left lateral Sims position.

The client's descending and sigmoid colon are optimally oriented for gravity-assisted fluid flow.

This anatomical positioning prevents fluid from immediately returning to the rectum and being prematurely expelled.

Place a waterproof pad under the buttocks and put on clean examination gloves.

The immediate environment is protected, and standard infection control precautions are implemented.

Maintaining hygiene and protecting linens is essential before initiating the invasive portion of the procedure.

Lubricate the distal 5 to 7.5 cm (2 to 3 inches) of the enema tubing tip.

The insertion tip is prepared for smooth entry into the anal sphincter.

A lubricated tip prevents mucosal tearing, pain, and vagal nerve stimulation during insertion.

Gently insert the tube 7.5 to 10 cm (3 to 4 inches) into the anal canal, directing it toward the umbilicus.

The tube rests safely in the rectum without penetrating too deeply.

Directing toward the umbilicus aligns with the natural curvature of the rectum, preventing bowel wall injury.

Release the tubing clamp and elevate the solution container 30 to 45 cm (12 to 18 inches) above the client's anus.

The enema solution flows steadily into the lower gastrointestinal tract at a safe pressure.

Proper height management prevents rapid fluid instillation, which can cause severe cramping, fluid expulsion, or tissue damage.

What is the safest action for the nurse to take regarding the administration of this new medication?

Insert a separate peripheral intravenous catheter to administer the antibiotic.

Connect the antibiotic tubing to the lowest Y-port on the current central line.

Stop the nutritional infusion temporarily, flush the line, and infuse the antibiotic.

Inject the antibiotic dose directly into the nutritional formula bag.

Show answer & explanation

Answer: Insert a separate peripheral intravenous catheter to administer the antibiotic.

Answer

The nurse should insert a separate peripheral intravenous catheter to administer the antibiotic.

Total parenteral nutrition (TPN) has high osmolarity and complex nutrient concentrations, making it highly susceptible to chemical incompatibilities and bacterial growth. Standard nursing practice requires a strictly dedicated line or a dedicated lumen for TPN administration. Because the client currently has a single-lumen catheter, the nurse must establish a new peripheral access site to safely administer the antibiotic.

Step-by-Step Solution

Identify the current infusion and its requirements.

The client is receiving total parenteral nutrition (TPN) via a single-lumen central line.

TPN contains high concentrations of glucose, amino acids, and potentially lipids, requiring specific administration protocols.

Evaluate the compatibility of the new medication with the existing line.

TPN requires a strictly dedicated line.

Administering medications through a TPN line increases the risk of chemical incompatibility, precipitation, and serious systemic infection.

Determine the safest alternative route for the new IV medication.

A new, separate peripheral IV site must be established.

Because the central line is a single lumen currently dedicated to TPN, the antibiotic cannot share this access point.

Key Concept

Total parenteral nutrition (TPN) requires a strictly dedicated intravenous line.

A nurse is planning basic care and comfort measures for an older adult client receiving palliative care who has severe cachexia, intractable bone pain, and a stage 3 sacral pressure injury. Which interventions should the nurse include in the plan of care? Select all that apply.

Select all that apply

Utilize a 30-degree lateral tilted position when turning the client in bed.

Instruct the unlicensed assistive personnel (UAP) to evaluate the granulation tissue of the pressure injury during daily bathing.

Keep the backrest of the bed elevated between 60 and 90 degrees continuously to maximize lung expansion.

Implement guided imagery and provide a preferred music playlist to serve as an adjunct to prescribed analgesics.

Inform the family that the client's sudden onset of severe confusion and restlessness is a normal physiological expectation of advanced age.

Cleanse the perineal area with a pH-balanced cleanser and apply a moisture barrier ointment after each incontinence episode.

Show answer & explanation

Answer: Utilize a 30-degree lateral tilted position when turning the client in bed.; Implement guided imagery and provide a preferred music playlist to serve as an adjunct to prescribed analgesics.; Cleanse the perineal area with a pH-balanced cleanser and apply a moisture barrier ointment after each incontinence episode.

Answer

The correct interventions include utilizing a 30-degree lateral tilted position, implementing guided imagery and music therapy, and cleansing the perineal area while applying a moisture barrier after incontinence episodes.

The correct interventions prioritize skin preservation and holistic comfort. A 30-degree lateral tilt safely offloads the sacrum without shifting excessive pressure to the greater trochanter, which is crucial for a cachectic client. Guided imagery and music are evidence-based non-pharmacologic adjuncts for intractable pain. Prompt cleaning with pH-balanced cleansers and application of barrier ointments prevent moisture-associated skin damage, which is vital for preventing the deterioration of the existing pressure injury.

Step-by-Step Solution

Analyze the client's clinical profile and identified risks.

The client has severe cachexia, intractable pain, and an existing stage 3 sacral pressure injury, creating a high risk for further skin breakdown and discomfort.

To determine which basic care interventions are safe and effective for this specific presentation.

Evaluate the proposed positioning and hygiene strategies.

The 30-degree lateral tilt offloads the sacrum safely. Barrier creams protect compromised skin from moisture. Conversely, a continuous high Fowler's position is contraindicated due to sacral shearing forces.

To select interventions that promote skin integrity and reject those that cause harm.

Identify appropriate non-pharmacological comfort measures.

Guided imagery and familiar music are valid, evidence-based adjuncts for pain management in palliative care.

To provide holistic comfort alongside pharmacological treatments.

Assess the delegation and education interventions for safety and accuracy.

Wound assessment cannot be delegated to UAPs, and sudden confusion is acute delirium, not normal aging.

To eliminate unsafe delegation practices and incorrect clinical education.

Key Concept

Comprehensive basic care for clients with severe immobility and altered skin integrity involves specific offloading techniques (30-degree lateral tilt), non-pharmacologic pain adjuncts, and diligent moisture management, while avoiding contraindicated positioning and improper delegation.

An older adult client is prescribed strict supine bed rest following a diagnostic lumbar puncture. When assisting the client with basic comfort and daily needs, which actions should the nurse implement? Select all that apply.

Select all that apply

Offer oral fluids frequently, such as water and juices.

Elevate the head of the bed to 45 degrees when assisting the client with eating.

Use a fracture bedpan to assist the client with elimination.

Delegate the evaluation of the lumbar puncture site for fluid leakage to the unlicensed assistive personnel (UAP).

Maintain a quiet, dimly lit environment to promote comfort and rest.

Reassure visiting family members that the client's newly developed acute confusion is an expected part of the aging process.

Show answer & explanation

Answer: Offer oral fluids frequently, such as water and juices.; Use a fracture bedpan to assist the client with elimination.; Maintain a quiet, dimly lit environment to promote comfort and rest.

Answer

The correct actions include offering frequent oral fluids, using a fracture bedpan for elimination, and maintaining a quiet, dim environment.

Following a lumbar puncture, the client must remain flat to prevent a spinal headache. Providing oral fluids helps replenish cerebrospinal fluid. A fracture bedpan allows for safe elimination without significantly elevating the hips or head, maintaining the required supine position. A quiet, dim environment promotes comfort and rest.

Step-by-Step Solution

Analyze the client's specific positional and safety requirements following a lumbar puncture.

The client requires a flat, supine position to prevent cerebrospinal fluid leakage and a subsequent spinal headache.

Maintaining the correct position dictates how basic care and comfort measures must be delivered.

Evaluate each intervention for safety, correct positioning, and appropriate scope of practice.

Providing fluids, using a fracture bedpan, and keeping the environment quiet align with safe care principles for a client who must remain flat.

Basic care must adapt to the client's medical restrictions without causing harm or violating delegation rules.

Question 1137Question →

A nurse is caring for a client who is $24$ hours postoperative following an open reduction and internal fixation (ORIF) of a right femoral shaft fracture. The client suddenly becomes intensely restless and confused. Assessment reveals a respiratory rate of $32$ breaths/minute, a heart rate of $122$ bpm, and a pinpoint red rash over the anterior chest. Arterial blood gas (ABG) results on room air are as follows:

Parameter	Result	Reference Range
$\text{pH}$	$7.48$	$7.35 - 7.45$
$\text{PaCO}_2$	$29\text{ mm Hg}$	$35 - 45\text{ mm Hg}$
$\text{PaO}_2$	$54\text{ mm Hg}$	$80 - 100\text{ mm Hg}$
$\text{HCO}_3^-$	$22\text{ mEq/L}$	$22 - 26\text{ mEq/L}$

Which action should the nurse perform FIRST to reduce the risk of severe physiological deterioration?

Coach the client to breathe slowly into a paper bag to correct the primary respiratory alkalosis

Administer high-flow oxygen via a non-rebreather mask and activate the rapid response team

Reposition the right lower extremity by elevating it above the level of the heart on two pillows

Perform a comprehensive neurological assessment using the Glasgow Coma Scale

Show answer & explanation

Answer: Administer high-flow oxygen via a non-rebreather mask and activate the rapid response team

Answer

The correct action is to administer high-flow oxygen via a non-rebreather mask and activate the rapid response team.

The correct answer addresses the immediate life-threatening crisis. The client is exhibiting the classic triad of fat embolism syndrome (FES): severe hypoxemia, neurological changes, and a petechial rash following a long bone fracture. The arterial blood gas reveals profound hypoxemia (

\text{PaO}_2

54\text{ mm Hg}

). The immediate priority is to maximize oxygenation to prevent ischemic brain injury and cardiac arrest, which requires high-flow oxygen and emergency team assistance.

Step-by-Step Solution

Analyze the clinical presentation and surgical history.

The client had a long bone fracture

24

hours ago and now presents with confusion, dyspnea, and a petechial rash. This is the classic clinical triad of Fat Embolism Syndrome (FES).

Identifying the underlying pathophysiological crisis dictates the required emergency response and helps anticipate complications.

Interpret the arterial blood gas (ABG) results.

The ABG demonstrates uncompensated respiratory alkalosis (

\text{pH } 7.48

\text{PaCO}_2\text{ } 29

) secondary to severe hypoxemia (

\text{PaO}_2\text{ } 54

The profound lack of oxygen in the blood is the primary threat to life. The low carbon dioxide is merely a compensatory physiological response (hyperventilation) driven by the hypoxia.

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

Applying high-flow oxygen and calling for emergency assistance is the absolute first priority.

Without immediate correction of the severe hypoxemia, the client will rapidly progress to anoxic brain injury or cardiac arrest. Other assessments and standard orthopedic interventions must be deferred.

Question 1138Question →

A critical care nurse is evaluating a client who has been receiving a continuous intravenous infusion of sodium nitroprusside at $3\text{ mcg/kg/min}$ for the management of a hypertensive emergency. The client's renal function has deteriorated over the last $48$ hours, evidenced by a urine output of $15\text{ mL/hr}$ and a serum creatinine level of $3.1\text{ mg/dL}$ . The client now presents with profound confusion, muscle twitching, and a mixed venous oxygen saturation ( $SvO_2$ ) of $88\%$ (normal range: $60\% - 80\%$ ). Based on these assessment data, which of the following pharmacological interventions should the nurse anticipate immediately?

Decrease the sodium nitroprusside infusion rate to

1.5\text{ mcg/kg/min}

and assess the client for signs of early shock.

Administer intravenous sodium thiosulfate via a secondary Y-site connection while maintaining the sodium nitroprusside infusion.

Discontinue the sodium nitroprusside and administer intravenous sodium thiosulfate.

Maintain the sodium nitroprusside infusion and administer intravenous sodium bicarbonate to correct the metabolic state.

Show answer & explanation

Answer: Discontinue the sodium nitroprusside and administer intravenous sodium thiosulfate.

Answer

Discontinue the sodium nitroprusside and administer intravenous sodium thiosulfate.

The client's presentation of altered mental status, muscle twitching, and an elevated

SvO_2

in the setting of prolonged sodium nitroprusside use and renal failure indicates cyanide toxicity. The definitive treatment requires immediately discontinuing the nitroprusside and administering sodium thiosulfate, which converts the cyanide into thiocyanate to be safely excreted.

Step-by-Step Solution

Analyze the client's current clinical presentation and medication history.

The client is receiving sodium nitroprusside, has acute kidney injury (oliguria, elevated creatinine), and presents with neurotoxicity alongside an abnormally high

SvO_2

Identifying the correlation between the continuous infusion, compromised renal clearance, and specific toxic symptoms is the first critical step in clinical reasoning.

Differentiate the physiological cause of the abnormally high

SvO_2

and neurological symptoms.

Sodium nitroprusside metabolizes into cyanide and thiocyanate, which require renal excretion. The high

SvO_2

indicates cells are unable to extract oxygen from the blood.

Cyanide toxicity inhibits cytochrome c oxidase in the cellular electron transport chain, halting aerobic respiration and causing oxygen to bypass the tissues entirely.

Determine the highest priority pharmacological intervention based on the identified toxicity.

The offending medication must be stopped immediately, and the specific antidote (sodium thiosulfate) must be administered.

Sodium thiosulfate acts as a sulfur donor, accelerating the conversion of toxic cyanide into less toxic thiocyanate for eventual elimination.

Question 1139Question →

An adult client is recovering on the medical-surgical unit two hours after a percutaneous liver biopsy. The nurse observes that over the last hour, the client's heart rate has increased from 76 to 114 bpm, and the blood pressure has shifted from 128/80 mm Hg to 110/88 mm Hg. The client reports feeling "restless" and has mild right upper quadrant discomfort. Which action should the nurse take immediately to minimize the risk of a severe complication?

Assess the abdomen for distention or rigidity and immediately notify the healthcare provider.

Assist the client into a high-Fowler's position to promote optimal diaphragmatic excursion.

Document the vital signs as a manifestation of anxiety and continue routine monitoring.

Auscultate bilateral lung sounds and instruct the client to use an incentive spirometer.

Show answer & explanation

Answer: Assess the abdomen for distention or rigidity and immediately notify the healthcare provider.

Answer

Assess the abdomen for distention or rigidity and immediately notify the healthcare provider.

The correct answer addresses the highest physiological priority: identifying and managing internal hemorrhage. A narrowing pulse pressure (systolic minus diastolic) combined with tachycardia and restlessness are classic early signs of hypovolemic shock. Because the liver is a highly vascular organ, bleeding is a primary risk after a biopsy. The nurse must assess for abdominal rigidity, which indicates intraperitoneal blood accumulation, and alert the provider immediately to prevent cardiovascular collapse.

Step-by-Step Solution

Analyze the trending vital signs.

The pulse pressure has narrowed significantly (from 48 mm Hg to 22 mm Hg) and the heart rate has increased significantly.

Identifying subtle vital sign trends is crucial for detecting early physiological decompensation.

Relate the findings to the specific procedure and client symptoms.

The liver is highly vascular; the vital sign changes combined with restlessness indicate early hemorrhagic shock from internal bleeding.

Linking procedure-specific risks to clinical manifestations guides appropriate nursing interventions.

Select the intervention that addresses the highest priority risk.

The nurse must assess for signs of intra-abdominal hemorrhage (rigidity) and escalate the findings to the provider.

Circulatory collapse is an immediate life threat requiring rapid medical management.

A client is admitted to the medical-surgical unit directly after undergoing a percutaneous liver biopsy. Which of the following nursing interventions should be implemented to minimize the risk of post-procedure complications? Select all that apply.

Select all that apply

Place the client in a right lateral position with a small towel or pillow under the puncture site.

Instruct the client to maintain strict bed rest for the duration prescribed by the healthcare provider.

Assess vital signs every 15 minutes during the initial post-procedure hour.

Assist the client into a high Fowler's position immediately to promote optimal respiratory function.

Document new-onset mild tachycardia as an expected stress response without further assessment.

Show answer & explanation

Answer: Place the client in a right lateral position with a small towel or pillow under the puncture site.; Instruct the client to maintain strict bed rest for the duration prescribed by the healthcare provider.; Assess vital signs every 15 minutes during the initial post-procedure hour.

Answer

The correct interventions include placing the client in a right lateral position, instructing them to maintain strict bed rest, and assessing vital signs every 15 minutes initially.

The correct interventions for a client following a percutaneous liver biopsy focus heavily on preventing and detecting hemorrhage. Placing the client in a right lateral position applies direct, necessary pressure to the liver capsule at the puncture site. Maintaining strict bed rest minimizes movement that could easily dislodge a fragile clot. Additionally, frequent vital sign monitoring ensures that subtle changes, which could indicate internal bleeding, are detected immediately.

Step-by-Step Solution

Identify the primary physiological risks associated with the specific procedure.

A percutaneous liver biopsy involves puncturing a highly vascular organ, making hemorrhage the most significant and immediate complication.

Understanding the most dangerous potential complications directs the focus of the nursing care plan toward risk reduction.

Select interventions that mechanically and physically prevent bleeding.

Positioning the client on the right side applies direct pressure, and maintaining bed rest prevents clot disruption.

Direct pressure and immobility are standard, evidence-based measures to achieve hemostasis after a percutaneous puncture of an internal organ.

Select interventions that allow for the early detection of complications.

Frequent vital sign monitoring is prioritized to catch subtle physiological changes.

Early indicators of shock, such as mild tachycardia, must be recognized immediately rather than dismissed as benign anxiety.

Key Concept

Post-procedure care for a liver biopsy prioritizes the prevention and early detection of hemorrhage through targeted positioning (right side-lying), immobility, and frequent physiological monitoring.
