A practical nurse (PN) at a rehabilitation center is caring for a client scheduled for a peripherally inserted central catheter (PICC) placement. The client has already signed the informed consent document but suddenly tells the PN, 'I have decided not to get the line placed.' In what order should the PN perform the following actions? Arrange the steps from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first cease preparations, then inquire about the client's reasons, contact the healthcare provider, and finally record the event in the chart.

When a client revokes consent, the nurse's first legal and ethical duty is to respect their autonomy by immediately stopping the procedure or preparations. Next, the nurse should gather data by exploring the client's concerns. This information is then relayed to the healthcare provider, who is responsible for discussing the implications of refusal. Finally, the nurse must document the entire sequence of events to maintain an accurate and legal medical record.

Step-by-Step Solution

Identify the immediate priority to protect client rights.

Cease any ongoing preparations for the catheter insertion.

The client has the right to revoke consent at any time. The PN's first action must be to honor this by stopping the procedure process.

Gather data regarding the client's change of mind.

Inquire about the client's reasons for deciding against the procedure.

Data collection helps determine if the refusal is due to anxiety, a misunderstanding, or a genuine desire to decline treatment.

Communicate the findings to the appropriate authority.

Contact the healthcare provider to report the client's change in decision.

The healthcare provider must be informed so they can evaluate the client, discuss the risks of refusal, and explore alternative therapies.

Ensure legal and accurate communication of the event.

Record the client's verbal refusal and the provider notification in the chart.

Documentation provides a legal record that the client revoked consent, the reasons why, and that the provider was informed.

Key Concept

Clients have the right to revoke informed consent at any time; the PN must immediately stop the procedure, assess concerns, notify the provider, and document.

Question 2802Question →

A practical nurse is providing care for a client who had a right total hip arthroplasty using a posterior approach the previous day. The nurse is preparing to assist the client with repositioning and comfort measures in bed. Which of the following actions is the most appropriate to maintain proper alignment and prevent joint dislocation?

Place an abduction wedge or pillow between the client's legs while turning them.

Elevate the head of the bed to a 90-degree angle while the client eats their meals.

Support the right leg with a trochanter roll to encourage internal rotation of the hip.

Allow the client to cross their legs at the ankles while resting in a supine position.

Show answer & explanation

Answer: Place an abduction wedge or pillow between the client's legs while turning them.

Answer

Place an abduction wedge or pillow between the client's legs while turning them.

Following a total hip arthroplasty with a posterior approach, maintaining abduction is a critical priority. Using an abduction wedge or pillow between the legs during turning prevents the affected leg from crossing the body's midline (adduction). This maintains the proper alignment of the femur in the acetabulum and prevents posterior dislocation of the prosthesis.

Step-by-Step Solution

Identify the type of surgery and the associated movement precautions.

The client had a right total hip arthroplasty via a posterior approach. Precautions include avoiding hip flexion greater than 90 degrees, avoiding internal rotation, and avoiding adduction (crossing the midline).

Understanding surgical precautions is essential for planning safe basic care and positioning.

Evaluate each nursing action against the established hip precautions.

Using an abduction pillow prevents adduction and is the correct action. Sitting at 90 degrees causes excessive flexion. Encouraging internal rotation or crossing legs (adduction) directly violates precautions and risks dislocation.

Applying the precautions to routine comfort measures ensures the prosthesis remains stable during recovery.

Show answer & explanation

Answer: Administering a scheduled dose of subcutaneous heparin to a client with deep vein thrombosis.; Reinforcing previous education about dietary potassium intake for a client who is newly prescribed oral spironolactone.; Auscultating the client's apical pulse for 60 seconds before administering a scheduled dose of oral digoxin.

Answer

The appropriate actions are administering subcutaneous heparin, reinforcing dietary education for spironolactone, and auscultating the apical pulse prior to digoxin administration.

The correct actions align with the practical nurse's scope of practice, which includes administering non-intravenous medications (such as subcutaneous heparin), collecting focused data (such as an apical pulse before digoxin), and reinforcing teaching initially provided by the registered nurse (such as dietary restrictions for spironolactone).

Step-by-Step Solution

Evaluate each action against the practical nurse (PN) scope of practice.

Subcutaneous injections, reinforcing established teaching, and pre-administration data collection (vital signs) are within the PN scope.

The PN safely cares for stable clients with predictable outcomes and supports RN interventions.

Identify actions that require registered nurse (RN) level assessment or are out of scope.

Intravenous (IV) push medications require RN licensure.

IV push medications have immediate effects and require continuous advanced clinical judgment.

Review the remaining actions for strict adherence to pharmacological safety guidelines.

Administer a prescribed intravenous push dose of potassium chloride to correct the deficit.

Withhold the furosemide and immediately notify the supervising registered nurse (RN).

Verify the client's identity using the barcode scanner and proceed with administration.

Show answer & explanation

Answer: Withhold the furosemide and immediately notify the supervising registered nurse (RN).

Answer

The correct action is to withhold the furosemide and notify the registered nurse (RN).

The correct action is to withhold the medication and notify the RN. Furosemide is a loop diuretic that causes potassium depletion. A serum potassium level of

2.9\text{ mEq/L}

indicates severe hypokalemia (normal range is typically

3.5

5.0\text{ mEq/L}

). Administering the medication could lower the potassium level further, leading to life-threatening cardiac dysrhythmias. The PN must withhold the dose and escalate this critical finding.

Step-by-Step Solution

Evaluate the client's serum potassium laboratory result.

Identify that a potassium level of

2.9\text{ mEq/L}

is significantly below the normal range (typically

3.5

5.0\text{ mEq/L}

To determine if the client's current physiological status is safe for the prescribed therapy.

Determine the pharmacological effect of furosemide.

Recognize that furosemide is a loop diuretic that causes the kidneys to excrete potassium.

Question 2805Question →

A resident in a rehabilitation facility requires assistance with elimination. The resident underwent a right-sided total hip arthroplasty using a posterior surgical approach two days ago. When positioning this resident to use a fracture bedpan, which action by the practical nurse is most appropriate?

Instruct the resident to use an overhead trapeze bar to lift the buttocks straight up while keeping the right leg slightly abducted.

Elevate the head of the bed to a high-Fowler's position of 80 to 90 degrees to facilitate gravity for easier bowel elimination.

Turn the resident onto their left side while allowing the right leg to naturally cross over the midline to slide the pan underneath.

Slide a standard, deep-rimmed bedpan under the resident to provide maximum sacral support and prevent spillage.

Show answer & explanation

Answer: Instruct the resident to use an overhead trapeze bar to lift the buttocks straight up while keeping the right leg slightly abducted.

Answer

The most appropriate action is to instruct the resident to use an overhead trapeze bar to lift the buttocks straight up while keeping the right leg slightly abducted.

For a posterior approach total hip arthroplasty, the hip must not be flexed beyond 90 degrees, and adduction or internal rotation must be completely avoided to prevent prosthesis dislocation. Using an overhead trapeze bar allows the client to lift their pelvis straight up without flexing the hip or rolling, while slight abduction maintains safe joint alignment for the placement of a fracture pan.

Step-by-Step Solution

Identify the specific surgical procedure and its associated precautions.

The client had a posterior total hip arthroplasty. Precautions include avoiding hip flexion greater than 90 degrees, avoiding adduction (crossing midline), and avoiding internal rotation.

Understanding the anatomical limitations post-surgery is essential to prevent prosthetic dislocation during routine basic care.

Evaluate the demands of placing a bedpan against the required post-operative precautions.

Using a bedpan normally requires lifting the pelvis or rolling the client, both of which can compromise hip alignment if performed incorrectly.

Basic care tasks must be adapted to fit within the safety parameters of the client's current physiological state.

Select the intervention that achieves the care goal without violating joint precautions.

Using an overhead trapeze bar with the leg abducted allows vertical lifting without dangerous flexion or adduction.

This action promotes client independence and comfort while strictly adhering to posterior hip precautions.

Key Concept

Maintenance of post-operative positioning precautions during basic care and comfort procedures.

Show answer & explanation

Answer: Notify the surgeon to return to the room and clarify the potential complications with the client

Answer

Notify the surgeon to return to the room and clarify the potential complications with the client

Informed consent requires that the client fully understands the procedure, including its risks, benefits, and alternatives. It is the legal responsibility of the healthcare provider performing the procedure to explain these elements. Because the client has expressed a lack of understanding about a specific surgical risk, the practical nurse must advocate for the client by asking the surgeon to return and provide further clarification before any signatures are collected.

Step-by-Step Solution

Analyze the client's statement

The client lacks understanding of the specific surgical risks.

Identifying a knowledge deficit is the first step in addressing informed consent issues.

Identify the practical nurse's scope of practice

The practical nurse cannot provide primary education regarding surgical risks, benefits, or alternatives.

The nurse's role in informed consent is limited to witnessing the signature and verifying voluntary agreement.

Determine the correct action

The nurse must contact the surgeon to provide the necessary education.

The healthcare provider who performs the procedure is legally responsible for explaining the risks and obtaining informed consent.

Question 2807Question →

A practical nurse is preparing to care for a client who has a severe Clostridioides difficile (C. diff) infection. The client also requires high-pressure wound irrigation of a large sacral pressure injury. Facility policy requires the use of an isolation gown, gloves, a surgical mask, and eye protection due to the high risk of fluid splashing. To comply with transmission-based precautions, which sequence must the nurse follow when donning the required personal protective equipment?

Put on the isolation gown, apply the surgical mask, place the eye protection, and then don the gloves.

Put on the isolation gown, don the gloves, apply the surgical mask, and then place the eye protection.

Don the gloves, put on the isolation gown, apply the surgical mask, and then place the eye protection.

Apply the surgical mask, place the eye protection, don the gloves, and then put on the isolation gown.

Show answer & explanation

Answer: Put on the isolation gown, apply the surgical mask, place the eye protection, and then don the gloves.

Answer

The correct sequence for donning personal protective equipment is to apply the isolation gown first, followed by the surgical mask, then the eye protection, and finally the gloves.

According to CDC guidelines, the correct order for donning personal protective equipment begins with the gown to cover the torso and arms. Next, the mask or respirator is applied to protect the respiratory tract, followed by goggles or a face shield for eye protection. The gloves are always donned last so they can be pulled over the cuffs of the isolation gown, creating a continuous barrier against pathogens.

Step-by-Step Solution

Identify the necessary personal protective equipment (PPE) based on the clinical scenario.

The nurse needs a gown and gloves for Contact Precautions (C. diff), plus a mask and eye protection for Standard Precautions due to splash risk (wound irrigation).

Understanding the required equipment is the prerequisite to applying it correctly.

Recall the standardized Centers for Disease Control and Prevention (CDC) guidelines for donning PPE.

The established sequence is: Gown, Mask or Respirator, Goggles or Face Shield, Gloves.

This sequence is specifically designed to minimize the risk of cross-contamination before entering the patient environment.

Evaluate each option against the standardized sequence to ensure gloves are donned last.

The option beginning with the gown, followed by the mask and eye protection, and ending with gloves is the only correct sequence.

Gloves must go on last so they can be extended over the wrists of the isolation gown to create a seamless protective barrier.

Question 2808Question →

A practical nurse is preparing discharge documents for a client. A hospital volunteer, who states they are the client's next-door neighbor, approaches the nurse and asks for a copy of the discharge medication list so they can pick up the prescriptions on the way home. The client is currently in the restroom and has not previously authorized this individual to receive health information. Which action should the practical nurse take?

Withhold the medication list until the client returns and can explicitly authorize the disclosure.

Provide the medication list because the volunteer is an official member of the hospital staff.

Give the volunteer the prescriptions but place them in a sealed envelope to protect privacy in the hallways.

Verbally read the medication names to the volunteer without handing over the printed document.

Show answer & explanation

Answer: Withhold the medication list until the client returns and can explicitly authorize the disclosure.

Answer

Withhold the medication list until the client returns and can explicitly authorize the disclosure.

The practical nurse has a legal and ethical duty to maintain client confidentiality. Information regarding a client's health, including discharge medications, cannot be shared with family, friends, or neighbors unless the client has explicitly granted permission. The nurse must wait for the client to return to obtain this authorization.

Step-by-Step Solution

Determine the individual's authorization status to receive protected health information.

The individual is not directly involved in the client's care and the client has not provided authorization for this disclosure.

The Health Insurance Portability and Accountability Act (HIPAA) and general privacy standards mandate that information is only shared on a 'need to know' basis or with explicit client consent.

Select the nursing action that prevents a confidentiality breach.

The nurse must refuse the request and wait for the client to return.

Only the client or their legally designated representative can authorize the release of medical information to a neighbor or friend.

Question 2809Question →

Prior to entering the room of a client placed on strict airborne and contact precautions, a practical nurse must apply multiple layers of protective gear. Arrange the following actions in the correct sequence for safely donning the required personal protective equipment (PPE) from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for donning PPE is to perform hand hygiene, put on the isolation gown, apply the N95 respirator, place the face shield or goggles, and finally don the clean gloves.

Following the standard CDC guidelines for donning PPE ensures that a continuous protective barrier is created systematically. Hand hygiene prevents initial contamination. The gown covers the largest surface area and goes on first. The respirator and eyewear protect the face and airway and are applied next. Finally, the gloves are applied last so they can successfully bridge the gap over the gown cuffs, completing the protective seal.

Step-by-Step Solution

Identify the need for hand hygiene as the foundational step.

Hand hygiene is placed first in the sequence.

Touching clean PPE with unwashed hands contaminates the equipment before it is even applied to the body.

Select the gown as the first physical piece of PPE to be applied.

The isolation gown is placed second.

The gown is the bulkiest item and protects the nurse's uniform, forming the base layer of the physical barrier.

Apply the respiratory protection next.

The N95 respirator is placed third.

Establishing a secure airway barrier is critical for airborne precautions. The mask must be applied before eyewear so the seal is flush against the face.

Add the eye protection.

The face shield or goggles are placed fourth.

Eyewear sits over the bridge of the nose and respirator to protect the mucous membranes of the eyes without breaking the respirator's seal.

Finish the barrier by applying gloves.

Donning clean gloves is placed last.

Gloves must go on last so the cuffs can be stretched over the sleeves of the gown, ensuring no skin on the wrists is exposed to the hazardous environment.

Show answer & explanation

Answer: Apply a pulse oximeter to measure the client's oxygen saturation level.; Elevate the head of the client's bed to maximize chest expansion.; Promptly notify the registered nurse (RN) about the acute changes in the client's condition.

Answer

The correct actions include elevating the head of the bed, applying a pulse oximeter, and immediately notifying the registered nurse (RN).

The client's sudden onset of agitation, confusion, and tachypnea are early, critical signs of hypoxia or a potential fat embolism syndrome, a known complication of long bone fractures. The appropriate nursing response is to prioritize Airway and Breathing by elevating the head of the bed to facilitate lung expansion, applying a pulse oximeter to gather objective oxygenation data, and immediately notifying the RN to escalate care. These actions directly address the potential life-threatening physiological adaptation failure.

Step-by-Step Solution

Analyze the client's clinical presentation.

The client has sudden confusion, agitation, and a respiratory rate of 28 breaths/minute following a femur fracture repair.

Identifying the onset and nature of symptoms is necessary to determine the level of urgency.

Apply the Airway, Breathing, and Circulation (ABC) prioritization framework.

Tachypnea and sudden confusion indicate a high probability of compromised breathing and oxygenation (e.g., hypoxia or fat embolism).

The ABC framework dictates that respiratory compromise must be addressed before pain management or routine care.

Select the immediate nursing interventions that support the ABCs and client safety.

Elevating the head of the bed improves breathing mechanics, applying a pulse oximeter provides objective oxygenation data, and notifying the RN ensures rapid escalation of care.

These actions are within the PN scope of practice and directly address the life-threatening potential of the client's symptoms.

Answer: Requesting the charge registered nurse (RN) to assume care of a client whose condition has rapidly deteriorated and now requires intravenous push medications.

Answer

Requesting the charge registered nurse (RN) to assume care of a client whose condition has rapidly deteriorated and now requires intravenous push medications.

The correct action demonstrates safe practice because the scope of practice for a practical nurse does not include administering intravenous push medications or managing clients who have become hemodynamically unstable. By collaborating with the charge RN to reassign this client, the PN ensures the client receives appropriate care while remaining within legal practice boundaries.

Step-by-Step Solution

Evaluate each nursing action against the established legal scope of practice for a Practical Nurse.

Identify tasks that require RN-level assessment, complex clinical judgment, or provider responsibilities.

Safe assignment and delegation require strict adherence to legal and facility role boundaries.

Analyze the action of transferring an unstable client to the RN.

Recognize that caring for hemodynamically unstable clients and administering intravenous push medications exceed the PN scope.

Escalating care to the RN ensures the client receives the appropriate level of life-saving intervention and maintains care within legal limits.

Question 2812Question →

A practical nurse is preparing to administer a combined dose of regular insulin and NPH insulin in a single syringe to a client with diabetes mellitus. Arrange the following steps for preparing this medication in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Roll the NPH vial, inject air into the NPH vial, inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.

When mixing regular (clear) and NPH (cloudy) insulin, the standard safety protocol is 'clear before cloudy'. This prevents the intermediate-acting NPH insulin from contaminating the short-acting regular insulin vial. The sequence of injecting air into the NPH first, then air into the regular, ensures that the needle does not carry regular insulin into the NPH vial during air injection, and prepares the vials for safe withdrawal.

Step-by-Step Solution

Roll the NPH insulin vial between the palms.

The cloudy suspension is mixed without creating air bubbles.

Ensures the insulin is evenly distributed before drawing the dose.

Inject air into the NPH insulin vial.

Pressure is equalized in the NPH vial.

Prevents a vacuum from forming when fluid is later withdrawn.

Inject air into the regular insulin vial.

Pressure is equalized in the regular insulin vial.

Prepares the vial for immediate withdrawal of the clear insulin.

Withdraw the regular insulin.

The clear insulin is drawn into the syringe first.

Prevents accidental contamination of the rapid/short-acting insulin with longer-acting insulin.

Withdraw the NPH insulin.

The combined dose is now completely drawn into the syringe.

The cloudy insulin is drawn last to complete the mixture safely without pushing regular insulin into the NPH vial.

The client's care plan requires a full-body mechanical sling lift. During the pre-use equipment check, the nurse discovers a small tear near one of the sling's upper attachment loops. Which action should the nurse take?

Tag the sling as defective, remove it from the room, and obtain an intact replacement before proceeding.

Complete the transfer as delegated after asking the registered nurse to verify that the tear is superficial.

Place the client in a semi-Fowler's position to shift their weight toward the undamaged lower loops during the lift.

Apply a vest restraint to the client and use it to manually assist the client into the wheelchair instead of using the lift.

Show answer & explanation

Answer: Tag the sling as defective, remove it from the room, and obtain an intact replacement before proceeding.

Answer

The nurse must tag the sling as defective, remove it from the client care area, and obtain an intact replacement before proceeding.

Any damage to a mechanical lift sling, regardless of size, compromises its structural integrity and poses an immediate fall hazard. Proper ergonomics and safe equipment use mandate that the nurse must immediately take defective items out of service, label them appropriately, and procure functioning replacements to protect the client from injury.

Step-by-Step Solution

Inspect the mechanical lift and sling prior to initiating the transfer.

A structural defect (a tear near an attachment loop) is identified.

Pre-use checks are a mandatory standard for the safe use of biomechanical equipment.

Determine the safety implications of the discovered defect.

The sling is deemed unsafe, as any fabric tear compromises weight-bearing integrity.

Using damaged equipment creates an imminent risk of a client fall and serious injury.

Take immediate corrective action to secure the environment.

The defective sling is tagged, removed from the room, and replaced.

Removing the hazard ensures neither this client nor others will be injured by the faulty device.

Reassure the client that a fast heart rate is an expected physiological response to gastrointestinal discomfort.

Notify the registered nurse immediately regarding the client's assessment findings and laboratory results.

Instruct the assistive personnel (AP) to assess the client's telemetry strip to determine the rhythm.

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the client's assessment findings and laboratory results.

Answer

The correct action is to notify the registered nurse immediately regarding the client's assessment findings and laboratory results.

Continuous nasogastric suctioning places the client at significant risk for electrolyte depletion, particularly hypokalemia. A serum potassium level of

2.8

mEq/L is critically low (normal range is

3.5

5.0

mEq/L). The presence of severe leg cramps, palpitations, and an irregular heart rate indicates symptomatic hypokalemia, which can rapidly progress to life-threatening cardiac dysrhythmias. Recognizing these risk factors and immediately escalating the critical findings to the registered nurse is the priority action for the practical nurse to ensure prompt medical intervention.

Step-by-Step Solution

Analyze the client's clinical presentation and laboratory data.

The client has a critically low serum potassium level (

2.8

mEq/L) and is exhibiting signs of symptomatic hypokalemia, including muscle cramps, palpitations, and an irregular heart rate.

Continuous nasogastric suction removes potassium-rich gastric secretions, placing the client at high risk for electrolyte imbalances.

Determine the priority nursing action based on the practical nurse scope of practice.

The practical nurse must immediately escalate these critical findings to the registered nurse.

Symptomatic hypokalemia can lead to life-threatening cardiac dysrhythmias and requires prompt medical intervention (such as intravenous potassium replacement) which is outside the independent scope of the practical nurse.

Question 2816Question →

A practical nurse is providing morning hygiene for an adult uncircumcised male client who has an indwelling urinary catheter. In what order should the nurse perform the following steps of perineal care? Arrange the actions in the correct sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with preparation and exposure, followed by cleansing from the cleanest area (meatus) to dirtier areas (catheter tubing, then scrotum), and concludes with replacing the foreskin to prevent injury.

Performing perineal care with an indwelling catheter relies on strict adherence to the principles of medical asepsis. The nurse must clean from the least contaminated area (the urethral meatus) to the most contaminated areas (the surrounding skin). Proper sequence requires initial preparation, exposure of the meatus, cleansing of the meatus, cleansing down the catheter (wiping away from the body), and then washing the surrounding tissue. Finally, replacing the foreskin is an absolute safety requirement to prevent paraphimosis.

Step-by-Step Solution

Don gloves and place a waterproof pad.

The environment and nurse are prepared for the procedure.

Standard precautions and bed protection are foundational first steps.

Retract the foreskin.

The urethral meatus is fully exposed.

Exposure is necessary to properly clean the anatomical site most at risk for infection.

Cleanse the meatus and glans.

The cleanest and most vulnerable area is sanitized.

Medical asepsis requires cleaning from the least contaminated (meatus) to the most contaminated area.

Wipe down the catheter tubing away from the meatus.

The proximal section of the catheter is cleaned.

Wiping away from the meatus prevents the mechanical introduction of microorganisms into the urethra (CAUTI prevention).

Wash the penile shaft and scrotum.

The surrounding perineal areas are cleansed.

These areas are considered more contaminated than the meatus and are washed last in the genital region.

Return the foreskin to its natural position.

The glans is covered and circulation remains uncompromised.

Failure to replace the foreskin can result in paraphimosis, causing severe edema and tissue damage.

Administer the heparin as prescribed to maintain deep vein thrombosis prophylaxis, but withhold the metoprolol due to the blood pressure.

Withhold both the heparin and the metoprolol, and immediately report the findings to the registered nurse.

Administer the metoprolol because the heart rate is within expected limits, but withhold the heparin due to the laboratory results.

Accept a verbal directive from the registered nurse to administer the heparin via intravenous push and withhold the metoprolol.

Show answer & explanation

Answer: Withhold both the heparin and the metoprolol, and immediately report the findings to the registered nurse.

Answer

The most appropriate action is to withhold both the heparin and the metoprolol, and immediately report the assessment findings to the registered nurse.

The correct action is to withhold both medications and notify the registered nurse. The client's blood pressure of

98/58\text{ mm Hg}

is borderline hypotensive, which warrants withholding the beta-blocker (metoprolol) to prevent further cardiovascular depression. Furthermore, the platelet count of

75,000/\text{mm}^3

indicates significant thrombocytopenia (normal is

150,000

400,000/\text{mm}^3

), placing the client at a high risk for bleeding; therefore, the anticoagulant (heparin) must also be withheld pending further medical evaluation.

Step-by-Step Solution

Analyze the client's vital signs in relation to the prescribed metoprolol.

The blood pressure is borderline hypotensive at

98/58\text{ mm Hg}

Metoprolol is a beta-blocker that lowers both heart rate and blood pressure. It should typically be withheld if the systolic blood pressure is below

100\text{ mm Hg}

to prevent cardiovascular collapse.

Evaluate the laboratory results in relation to the prescribed heparin.

The platelet count is critically low at

75,000/\text{mm}^3

(thrombocytopenia).

A normal platelet count is

150,000

400,000/\text{mm}^3

. Administering an anticoagulant to a client with significant thrombocytopenia drastically increases the risk of severe, life-threatening hemorrhage.

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

Both medications must be withheld and the findings immediately escalated to the registered nurse.

The practical nurse is responsible for recognizing abnormal pre-administration assessment data, preventing adverse drug events, and reporting critical findings to the supervising nurse or provider.

Question 2818Question →

An older adult client on an orthopedic unit is preparing for a scheduled total knee arthroplasty later this morning. The orthopedic surgeon has already visited the client to discuss the surgery. The charge nurse directs the practical nurse (PN) to assist with the informed consent document. Which of the following actions are legally appropriate for the PN to take? Select all that apply.

Select all that apply

Witnessing the client's signature on the surgical consent form

Explaining the potential surgical risks and complications to the client

Confirming that the client is signing the document voluntarily

Detailing the available alternative treatments if the client refuses surgery

Notifying the surgeon immediately if the client expresses confusion about the surgery

Show answer & explanation

Answer: Witnessing the client's signature on the surgical consent form; Confirming that the client is signing the document voluntarily; Notifying the surgeon immediately if the client expresses confusion about the surgery

Answer

The legally appropriate actions for the PN are witnessing the client's signature, confirming the document is signed voluntarily, and notifying the surgeon if the client expresses confusion.

In the informed consent process, the practical nurse acts as a witness and client advocate. The PN is legally permitted to witness the physical signature on the consent form and must verify that the client is signing voluntarily and possesses the cognitive capacity to do so. Additionally, if the client verbalizes hesitation or confusion, the PN's duty is to advocate for the client by delaying the signature and notifying the healthcare provider so they can provide necessary clarification.

Step-by-Step Solution

Analyze the role of the practical nurse (PN) in the informed consent process.

The PN's role is strictly limited to advocating for the client, witnessing the signature, and ensuring the client is competent and acting voluntarily.

Understanding the legal scope of practice prevents unauthorized medical disclosures.

Identify the responsibilities that belong exclusively to the healthcare provider.

The provider must explain the procedure, risks, benefits, and alternative treatments.

The provider possesses the comprehensive medical knowledge required to obtain informed consent.

Evaluate each option against the PN scope of practice.

Witnessing the signature, verifying voluntary action, and notifying the provider of client confusion are within the PN's scope. Explaining risks and detailing alternatives are not.

Selecting only the actions within the legal boundaries ensures safe and effective care.

Key Concept

The practical nurse's role in informed consent is limited to witnessing the signature, verifying voluntary consent, and advocating for the client by notifying the provider if further clarification is needed.

Question 2819Question →

A practical nurse is preparing to administer scheduled medications to a client who is alert and oriented. Upon bringing the medications to the bedside, the electronic barcode scanner fails to read the client's identification band. Which action should the nurse take next to prevent a medication error?

Ask the client to state their full name and date of birth, and verify this against the medication record.

Retrieve a replacement identification band from the client's chart and scan it at the bedside.

Leave the prepared medications on the overbed table while locating a functioning barcode scanner.

Verify the client's identity by checking the room and bed number listed on the medication record.

Show answer & explanation

Answer: Ask the client to state their full name and date of birth, and verify this against the medication record.

Answer

The correct action is to manually verify the client's identity by asking them to state their full name and date of birth, and comparing this information directly to the electronic medication administration record.

When a barcode scanning system fails, the nurse is still legally and ethically required to perform proper client identification before administering any medication. For an alert and oriented client, the most appropriate and safest method is to ask the client to state two acceptable identifiers—typically their full name and date of birth—and compare this information directly to the medication administration record. This ensures the right medication is given to the right client.

Step-by-Step Solution

Recognize that the failure of the electronic barcode scanner does not eliminate the strict requirement to verify two client identifiers.

Alternative, acceptable identifiers must be used before proceeding.

Maintaining client safety and adhering to medication administration rights is mandatory regardless of technology function.

Identify the client's cognitive status based on the scenario.

The client is alert and oriented, making them capable of participating in their own identification.

Alert clients are the most reliable source for their own identifying information.

Perform manual verification using two standard, acceptable identifiers.

The nurse asks the client for their full name and date of birth, and checks it against the electronic medication administration record.

This action fulfills the two-identifier rule and directly prevents medication administration errors.

Question 2820Question →

An adult client is transferred to the surgical unit following a subtotal thyroidectomy. The client reports mild discomfort at the anterior neck incision site. Which positioning intervention is most appropriate for the practical nurse to implement to promote comfort and prevent complications?

Maintain the bed in a semi-Fowler's position at 30 to 45 degrees while supporting the head and neck with pillows.

Place the client flat in a supine position with a small rolled towel placed directly beneath the cervical spine.

Assist the client into a continuous lateral side-lying position to facilitate the drainage of oral secretions.

Position the client upright at 90 degrees and instruct them to rest their chin firmly against their chest.

Show answer & explanation

Answer: Maintain the bed in a semi-Fowler's position at 30 to 45 degrees while supporting the head and neck with pillows.

Answer

Maintain the bed in a semi-Fowler's position at 30 to 45 degrees while supporting the head and neck with pillows.

Placing the client in a semi-Fowler's position (30 to 45 degrees) uses gravity to help reduce edema in the head and neck, which is critical for protecting the airway after thyroid surgery. Simultaneously supporting the head and neck with pillows keeps the cervical spine in a neutral position, preventing tension on the surgical incision and minimizing pain.

Step-by-Step Solution

Analyze the surgical procedure and its anatomical location.

The client had a subtotal thyroidectomy, meaning an incision was made in the anterior neck.

Understanding the surgical site is necessary to anticipate potential complications such as airway compromise or bleeding.

Identify the primary goals for post-thyroidectomy positioning.

The goals are to maintain a patent airway, reduce tissue edema, and prevent tension or stretching on the neck suture line.

Proper positioning directly impacts the client's respiratory status and wound healing.

Evaluate the positioning options against the identified goals.

The semi-Fowler's position with head and neck support meets all criteria by decreasing swelling via gravity and keeping the neck in a neutral alignment.

This specific alignment prevents hyperextension and hyperflexion, both of which are dangerous post-thyroidectomy.
