Following an abdominal hysterectomy, a client is transferred to the surgical unit. During the initial data collection, the practical nurse notes a heart rate of 114 beats/min and a blood pressure of 94/58 mm Hg. The client states, 'I feel a little nauseous and my incision hurts.' Which action should the nurse take first?

Show answer & explanation

Answer: Notify the registered nurse about the current vital signs.

Answer

The correct action is to notify the registered nurse about the current vital signs.
The client is exhibiting tachycardia and borderline hypotension, which are early physiological adaptations to fluid volume deficit or hemorrhage following surgery. Within the practical nursing scope of practice, recognizing these signs of potential shock requires immediate escalation to the registered nurse for further assessment and intervention.

Step-by-Step Solution

1
Evaluate the client's vital signs and postoperative status.
The heart rate of 114 beats/min and blood pressure of 94/58 mm Hg are identified as abnormal deviations from expected postoperative parameters.
Tachycardia and mild hypotension are early physiological adaptations signaling potential hypovolemia or hemorrhage.
2
Prioritize nursing care based on the ABC (Airway, Breathing, Circulation) framework.
Circulatory stability is prioritized over the client's reports of pain and nausea.
Addressing potential shock takes clinical precedence over general comfort measures.
3
Determine the safest action within the practical nursing scope of practice.
The abnormal findings are immediately reported to the registered nurse.
The practical nurse must escalate signs of acute instability to ensure prompt medical or advanced nursing intervention.

Question 42Question →

A practical nurse (PN) is collecting data on a client admitted with a severe exacerbation of ulcerative colitis. The client has had several large, bloody bowel movements over the past four hours. The client's current vital signs are: heart rate 112 beats/min, blood pressure 106/68 mm Hg, and respiratory rate 22 breaths/min. The client's admission vital signs were: heart rate 78 beats/min, blood pressure 134/82 mm Hg, and respiratory rate 16 breaths/min. The client appears restless and reports abdominal cramping. Which action should the PN take first?

Show answer & explanation

Answer: Notify the registered nurse (RN) about the changes in the client's condition.

Answer

The correct action is to notify the registered nurse (RN) about the changes in the client's condition.
The client is exhibiting early, compensatory signs of hypovolemic shock due to significant blood and fluid loss from the ulcerative colitis exacerbation. The increased heart rate, dropping blood pressure, and new-onset restlessness (indicating decreased cerebral perfusion) require immediate medical intervention. Within the practical nurse (PN) scope of practice, recognizing acute decompensation and immediately notifying the registered nurse (RN) is the highest priority action to ensure life-saving treatments are initiated promptly.

Step-by-Step Solution

1
Analyze the client's current vital signs and compare them to the admission baseline.
The heart rate has increased significantly (from 78 to 112 beats/min), blood pressure has dropped (from 134/82 to 106/68 mm Hg), and the client is restless.
Identifying trends in vital signs is crucial for detecting physiological decompensation early.
2
Correlate the assessment findings with the client's clinical presentation.
The history of large, bloody bowel movements combined with tachycardia, relative hypotension, and restlessness indicates acute fluid volume deficit and impending hypovolemic shock.
Understanding the cause of the vital sign changes guides appropriate prioritization and intervention.
3
Determine the highest priority nursing action based on the Airway, Breathing, and Circulation (ABC) framework and the PN scope of practice.
The priority is to address the circulatory compromise by immediately notifying the RN, who can initiate intravenous fluid resuscitation and contact the healthcare provider.
Escalating a critical change in condition ensures the client receives timely, life-saving interventions.

Question 43Question →

A practical nurse (PN) provides care for a 75-year-old resident in a skilled nursing facility who is receiving oral antibiotics for a lower urinary tract infection. During the afternoon shift, the PN discovers the resident is unusually restless, picking at their clothing, and breathing at a rate of 26 breaths/min. Which actions should the PN prioritize? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Measure the resident's blood pressure, heart rate, and peripheral oxygenation.; Evaluate the resident's capillary refill time and extremity skin temperature.; Contact the facility charge nurse to report the sudden change in condition.

Answer

The correct actions involve prioritizing Airway, Breathing, and Circulation (ABC) data collection and escalating the findings. The PN should measure blood pressure, heart rate, and oxygenation, evaluate capillary refill and skin temperature, and immediately contact the charge nurse.
In an older adult with a localized infection, new-onset restlessness, confusion, and tachypnea are early warning signs of physiological decompensation, such as sepsis or hypoxia. The practical nurse must prioritize data collection related to Airway, Breathing, and Circulation (ABCs) by measuring oxygen saturation, blood pressure, heart rate, and peripheral perfusion (capillary refill, skin temperature). Because these findings suggest a critical shift in the client's status, immediate escalation to the supervising nurse is required to initiate prompt medical intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The new onset of restlessness and tachypnea (26 breaths/min) in a client with an active infection points toward systemic physiological compromise, such as early sepsis or hypoxia.
Recognizing acute changes from baseline is the foundation of clinical judgment and physiological adaptation.
2
Prioritize nursing interventions using the ABC framework.
Collecting comprehensive circulatory and respiratory data (blood pressure, oxygenation, capillary refill) takes precedence over routine comfort care.
Rapid identification of hemodynamic instability is essential for client survival and dictates immediate priorities.
3
Determine the appropriate scope of practice and next steps.
The PN must report these critical findings to the supervising registered nurse (RN) or provider.
Systemic physiological decompensation requires RN-level assessment and rapid provider-level medical orders.

Question 44Question →

An older adult client is resting in the surgical unit following a left cataract extraction. The client reports mild postoperative discomfort and asks to be repositioned in bed. Which positioning strategy should the licensed practical nurse implement?

Show answer & explanation

Answer: Elevate the head of the bed 30∘30^\circ to 45∘45^\circ and assist the client into a supine or right side-lying position.

Answer

Elevate the head of the bed 30 to 45 degrees and assist the client into a supine or right side-lying position.
Following cataract extraction, it is critical to prevent increases in intraocular pressure (IOP) while providing comfort. Elevating the head of the bed 30∘30^\circ to 45∘45^\circ and placing the client either supine or on the non-operative side (the right side, in this case) achieves optimal comfort while protecting the surgical site from undue pressure.

Step-by-Step Solution

1
Identify the client's surgical procedure and the affected side.
The client underwent a left cataract extraction.
Determining the exact operative side is essential for selecting a safe position that avoids direct pressure on the surgical site.
2
Determine the primary postoperative goal for basic care and comfort following eye surgery.
The primary goal is to prevent any increase in intraocular pressure (IOP) while keeping the client comfortable.
Increased IOP can cause bleeding, suture rupture, or permanent vision loss in the operated eye.
3
Evaluate the positioning options against the goal of maintaining low IOP.
Elevating the head of the bed (30 to 45 degrees) and positioning the client on the non-operative (right) side or supine safely achieves this goal.
Lying flat, lying on the operative side, or bending at the waist all increase IOP and are incorrect comfort measures.

Four hours after a percutaneous liver biopsy, an assigned client reports the new onset of right shoulder pain. The client's baseline vital signs were a blood pressure of 134/82 mm Hg134/82 \text{ mm Hg} and a heart rate of 76 beats/min76 \text{ beats/min}. The licensed practical nurse (LPN/LVN) assesses current vital signs, noting a blood pressure of 108/72 mm Hg108/72 \text{ mm Hg} and a heart rate of 114 beats/min114 \text{ beats/min}. Which action must the nurse take first?

Show answer & explanation

Answer: Immediately report the assessment findings to the supervising registered nurse.

Answer

Immediately report the assessment findings to the supervising registered nurse.
The client's new right shoulder pain is referred pain from diaphragmatic irritation, which can occur when blood accumulates after a liver biopsy. Combined with tachycardia and a dropping blood pressure, these findings strongly suggest internal bleeding and developing hypovolemic shock. The LPN/LVN must immediately escalate these critical findings to the RN or healthcare provider for rapid intervention.

Step-by-Step Solution

1
Analyze the client's symptoms.
The client has new-onset right shoulder pain after a liver biopsy.
Right shoulder pain is a classic sign of referred pain caused by phrenic nerve irritation, often due to blood accumulating under the diaphragm (subdiaphragmatic hematoma).
2
Compare the current vital signs to the baseline.
The blood pressure has dropped from 134/82 mm Hg134/82 \text{ mm Hg} to 108/72 mm Hg108/72 \text{ mm Hg}, and the heart rate has increased significantly from 76 beats/min76 \text{ beats/min} to 114 beats/min114 \text{ beats/min}.
Identifying trends in vital signs is crucial for detecting early physiological decline.
3
Synthesize the findings to determine the clinical risk.
The combination of referred pain, hypotension, and tachycardia indicates internal hemorrhage and early hypovolemic shock.
The body compensates for blood loss by increasing the heart rate, while the blood pressure begins to fall as volume depletes.
4
Determine the priority nursing action based on the LPN/LVN scope of practice.
The priority is to immediately notify the supervising registered nurse or healthcare provider.
A life-threatening complication requires immediate escalation for advanced assessment, potential fluid resuscitation, and medical intervention beyond the LPN/LVN scope.

Question 46Question →

While monitoring an older adult client who is being treated with a continuous intravenous heparin infusion for a pulmonary embolism, a practical nurse (PN) reviews the trend of the client's vital signs. Over the past four hours, the client's heart rate has climbed from 78 bpm78\text{ bpm} to 112 bpm112\text{ bpm}, and the blood pressure has trended downward from 134/82 mmHg134/82\text{ mmHg} to 104/68 mmHg104/68\text{ mmHg}. The client currently reports feeling faint. What is the priority action for the PN?

Show answer & explanation

Answer: Escalate the clinical findings immediately to the primary registered nurse.

Answer

The priority action is to escalate the clinical findings immediately to the primary registered nurse.
The client's presentation of a climbing heart rate, dropping blood pressure, and faintness while receiving a continuous heparin infusion strongly points to internal hemorrhage and early hypovolemic shock. Because the client is experiencing a critical, life-threatening adverse effect that requires complex assessment and potential medical intervention (such as stopping the infusion or administering fluids), the practical nurse must prioritize immediately notifying the registered nurse to initiate a rapid response.

Step-by-Step Solution

1
Analyze the client's medication and current symptoms.
The client is on a continuous heparin infusion (high risk for bleeding) and presents with new-onset tachycardia, decreasing blood pressure, and faintness.
Identifying the relationship between the pharmacological therapy and new physical symptoms is essential for recognizing adverse drug events.
2
Interpret the vital sign trends and prioritize care.
The shift from normal baseline vital signs to tachycardia and borderline hypotension indicates early hypovolemic shock, likely due to internal hemorrhage.
Early recognition of shock requires prioritizing Circulation and immediate medical intervention to prevent cardiovascular collapse.
3
Determine the appropriate action within the practical nurse's scope of practice.
The PN must immediately notify the registered nurse rather than independently altering intravenous medications or delaying care.
Managing a hemodynamically unstable client and titrating intravenous anticoagulants fall outside the PN scope of practice.

Key Concept

Monitoring for adverse effects of anticoagulant therapy and adhering to the practical nurse scope of practice.
Question 47Question →

A practical nurse is preparing to provide oral hygiene for a client who is unresponsive following a severe traumatic brain injury. In what order should the nurse 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 nurse must first place the client in a side-lying position, followed by placing a towel and emesis basin, inserting a padded tongue blade, cleaning the oral mucosa, and finally applying a lip moisturizer.
The correct sequence prioritizes airway safety above all else. Positioning the client laterally ensures fluids drain out of the mouth rather than pooling in the oropharynx, effectively preventing aspiration. Preparation of the environment (towel/basin) follows to maintain hygiene. Opening the mouth safely with a padded tongue blade prevents bite injuries during the cleaning process. The actual cleaning occurs next, and applying lip moisturizer is the final basic care comfort measure.

Step-by-Step Solution

1
Place the client in a side-lying position.
The airway is protected from fluid pooling.
In an unresponsive client, lateral positioning uses gravity to drain secretions and prevents aspiration.
2
Place a towel under the chin and position an emesis basin against the cheek.
The bed and gown are shielded from fluids.
Maintaining a clean and dry environment promotes client comfort and prevents skin breakdown.
3
Insert a padded tongue blade gently between the back teeth.
The mouth is held open safely.
Unresponsive clients may have an unpredictable bite reflex; using a padded blade protects the nurse and prevents tooth damage.
4
Clean the teeth and oral mucosa using a moistened foam swab.
Plaque and bacteria are removed from the oral cavity.
Thorough cleansing reduces the risk of ventilator-associated pneumonia or oral infections.
5
Apply a water-soluble moisturizer to the client's lips.
The lips are hydrated and protected.
Moisture prevents the lips from cracking, which can lead to bleeding and infection.

A practical nurse enters the room of a client receiving intravenous fluids via a central venous catheter. The nurse observes that the intravenous tubing has become disconnected from the catheter hub. The client is suddenly grasping their chest, gasping for air, and appears cyanotic. In which order should the nurse perform the following emergency actions to mitigate the risk of a fatal complication? Arrange the steps from first (highest priority) to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of actions for a suspected air embolism is to first clamp the catheter, then position the client in the left lateral Trendelenburg position, followed by administering high-flow oxygen, activating the emergency response team, and finally obtaining a full set of vital signs.
When an air embolism is suspected due to a disconnected central line, the immediate goal is to prevent further air entry and minimize the physiological impact of the air already introduced. The nurse must first clamp the catheter to eliminate the source of the leak. Next, the left lateral Trendelenburg position is utilized to physically trap the air in the apex of the right ventricle. Oxygen is then applied to treat severe hypoxia and help dissolve the embolus. With these immediate mechanical and respiratory safeguards established, the nurse activates the emergency response team and then gathers vital signs to provide objective data to the arriving medical providers.

Step-by-Step Solution

1
Clamp the open lumen of the central venous catheter.
Prevents further air entry into the bloodstream.
Stopping the root cause of the complication is always the absolute first step in an air embolism emergency.
2
Place the client in the left lateral Trendelenburg position.
Traps the air embolus in the right ventricle.
This utilizes gravity to keep the air bubble away from the pulmonary outflow tract, reducing the risk of a massive pulmonary embolism.
3
Administer high-flow oxygen via a non-rebreather mask.
Treats hypoxia and shrinks the embolus.
High concentrations of oxygen wash out nitrogen from the blood, helping to dissolve the air bubble more quickly.
4
Activate the facility emergency response team and inform the supervising nurse.
Initiates advanced collaborative care.
The practical nurse must escalate this critical emergency for advanced cardiovascular life support and medical intervention.
5
Assess the client's vital signs and oxygen saturation.
Provides objective baseline data.
Continuous monitoring is required after life-saving maneuvers and escalation have been completed.

Key Concept

Reduction of risk potential during an air embolism involves immediate source control, specific protective positioning, oxygenation, and rapid escalation.
Question 49Question →

A practical nurse is caring for a client who is 4 hours postoperative following an open cholecystectomy. The registered nurse (RN) is managing the client's continuous intravenous (IV) fluids and delegates the administration of scheduled oral metoprolol, oral oxycodone, and a PRN dose of IV push ondansetron to the practical nurse. The client's current vital signs are blood pressure 86/52 mmHg, heart rate 118 bpm, and respiratory rate 16 breaths/min. The client reports a pain level of 7 on a 0 to 10 scale. Which action should the practical nurse take first?

Show answer & explanation

Answer: Refuse the delegated intravenous push medication, withhold the oral medications, and immediately report the vital signs to the registered nurse.

Answer

The practical nurse must refuse the out-of-scope intravenous push medication, withhold the oral antihypertensive and opioid medications due to the client's hemodynamic instability, and immediately report the findings to the supervising registered nurse.
The client's vital signs (blood pressure 86/52 mmHg, heart rate 118 bpm) indicate potential hypovolemic shock or hemorrhage, which is a circulation (ABC) priority. Metoprolol (a beta-blocker) and oxycodone (an opioid) both lower blood pressure and must be withheld to prevent cardiovascular collapse. Additionally, administering IV push medications like ondansetron is outside the practical nurse's scope of practice. The nurse must refuse the unsafe delegation and escalate the critical clinical findings to the registered nurse immediately.

Step-by-Step Solution

1
Analyze the delegated tasks against the practical nurse scope of practice.
Administration of intravenous push medications (ondansetron) is identified as out of scope and must be refused.
Nursing practice acts generally prohibit practical nurses from administering medications via the intravenous push route.
2
Evaluate the client's current vital signs in the context of their postoperative status.
Blood pressure of 86/52 mmHg and a heart rate of 118 bpm are identified as critical abnormalities.
These vital signs in a 4-hour postoperative client strongly suggest early hypovolemic or hemorrhagic shock, requiring immediate attention.
3
Analyze the pharmacological effects of the scheduled oral medications on the client's current physiological state.
Both metoprolol (a beta-blocker) and oxycodone (an opioid) are identified as contraindicated.
Metoprolol lowers blood pressure and heart rate, while oxycodone causes vasodilation and lowers blood pressure; both would exacerbate the client's cardiovascular compromise.
4
Determine the priority nursing action based on scope and safety.
Withhold the oral medications, refuse the IV push task, and escalate immediately to the registered nurse.
Immediate RN assessment and intervention (such as IV fluid boluses) are required to manage the hemodynamic instability.

Key Concept

The practical nurse must strictly adhere to their scope of practice by refusing IV push delegations, while concurrently utilizing clinical judgment to withhold medications (like beta-blockers and opioids) that would exacerbate early signs of shock.

A practical nurse is providing postoperative care for a client who recently returned to the unit following a right-sided cataract extraction. Which basic care and positioning interventions should the nurse implement to prevent complications? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Elevate the head of the bed to 30 to 45 degrees.; Position the client on the unoperated (left) side.; Instruct the client to avoid bending forward at the waist.

Answer

The nurse should elevate the head of the bed, position the client on the unoperated side, and instruct the client to avoid bending forward at the waist.
Following cataract surgery, preventing an increase in intraocular pressure (IOP) is critical. Elevating the head of the bed promotes venous drainage, positioning on the unoperated side prevents direct pressure on the affected eye, and avoiding bending at the waist prevents sudden spikes in IOP.

Step-by-Step Solution

1
Identify the surgical procedure and its primary postoperative risk.
The client had a right-sided cataract extraction. The primary risk is increased intraocular pressure (IOP).
Understanding the procedure is essential for determining safe positioning and activity guidelines.
2
Evaluate each intervention for its effect on intraocular pressure.
Elevating the head, lying on the unoperated side, and avoiding bending at the waist all help keep IOP low.
Basic care interventions must align with preventing complications specific to the surgery.
3
Identify contraindicated positions.
Lying flat and lying on the operative side both increase IOP and are contraindicated.
Avoiding harmful positions protects the surgical site from pressure and increased blood flow.

Key Concept

Postoperative basic care and positioning following eye surgery focuses on preventing increased intraocular pressure.
Question 51Question →

The nursing care team is managing the daily needs of a client who is non-ambulatory and receiving continuous enteral feedings via a gastrostomy tube following a recent abdominal surgery. When implementing basic hygiene and comfort measures, which actions are appropriate for the practical nurse (PN) to perform? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Maintain the head of the bed elevated at 30 to 45 degrees while assisting the client with repositioning.; Utilize a friction-reducing draw sheet and an additional staff member when sliding the client up in bed.; Apply a zinc oxide-based moisture barrier cream to the client's perineal area after cleansing incontinent episodes.

Answer

The correct actions are maintaining the head of the bed elevated, utilizing a draw sheet for repositioning, and applying a moisture barrier cream to the perineal area.
Maintaining the head of the bed at an angle of 30 to 45 degrees prevents aspiration of gastric contents during continuous tube feedings. Using a draw sheet with assistance minimizes shearing forces that can cause skin breakdown when moving a bedbound client. Applying a moisture barrier cream protects fragile skin from the corrosive effects of urine and feces, thereby preventing maceration and perineal dermatitis.

Step-by-Step Solution

1
Analyze the client's primary clinical risks based on the scenario.
The client is bedbound, increasing the risk for skin breakdown, and receives continuous enteral feedings, increasing the risk for aspiration.
Identifying the client's vulnerabilities is the first step in determining safe and effective basic care interventions.
2
Evaluate each care intervention against safety standards and the PN scope of practice.
Elevating the head of the bed, using a draw sheet, and applying barrier cream are safe, evidence-based practices. Ring cushions, flat positioning during feeding, and delegating assessment are unsafe or out of scope.
Nursing actions must protect the airway, maintain skin integrity without causing harm, and remain within legal practice boundaries.
3
Select all interventions that correctly address the client's comfort and basic care needs while maintaining safety.
The appropriate actions are maintaining head elevation, using a draw sheet, and applying barrier cream.
These interventions directly mitigate the identified risks of aspiration and tissue damage.

- Heart rate: 112 beats/min112\text{ beats/min}
- Hemoglobin: 10.4 g/dL10.4\text{ g/dL}
- Platelet count: 85,000/mm385,000/\text{mm}^3

Which action should the PN take FIRST?

Show answer & explanation

Answer: Withhold the scheduled enoxaparin and celecoxib, and immediately notify the registered nurse.

Answer

Withhold the scheduled enoxaparin and celecoxib, and immediately notify the registered nurse.
The correct action demonstrates safe pharmacological practice and clinical judgment. The client has a critically low platelet count (85,000/mm385,000/\text{mm}^3) alongside early signs of shock (tachycardia and hypotension). Enoxaparin (an anticoagulant) and celecoxib (an NSAID) both impair the body's ability to clot. Administering them would place the client at extreme risk for severe hemorrhage. The practical nurse must withhold these medications and immediately escalate the situation to the registered nurse for prompt medical intervention.

Step-by-Step Solution

1
Analyze the laboratory results and recognize abnormalities.
The platelet count is 85,000/mm385,000/\text{mm}^3, which indicates critical thrombocytopenia (normal is 150,000−400,000/mm3150,000 - 400,000/\text{mm}^3).
Identifying thrombocytopenia is crucial because it significantly increases the client's risk for spontaneous or medication-induced hemorrhage.
2
Correlate laboratory findings with the current vital signs.
The client is exhibiting tachycardia (112 beats/min112\text{ beats/min}) and mild hypotension (96/58 mmHg96/58\text{ mmHg}).
These borderline vital signs, combined with low platelets in a postoperative client, are early physiological indicators of internal bleeding or shock.
3
Evaluate the scheduled pharmacological therapies against the clinical data.
Enoxaparin is an anticoagulant and celecoxib is an NSAID; both impair clotting and are contraindicated given the client's thrombocytopenia and signs of shock.
Administering either medication could precipitate or exacerbate a life-threatening hemorrhage.
4
Determine the most appropriate nursing action within the PN scope of practice.
The medications must be withheld and the registered nurse must be notified immediately.
The PN scope of practice requires safeguarding the client from contraindicated treatments and escalating critical clinical deterioration to the supervising RN for advanced assessment.

While evaluating a client who returned from the post-anesthesia care unit 4 hours ago following a subtotal thyroidectomy, a practical nurse notes that the client appears increasingly restless. The client states, "My neck feels a little tight." The current vital signs reveal a heart rate of 116 beats/minute, a blood pressure of 96/58 mm Hg, and a respiratory rate of 22 breaths/minute. Which action is the priority for the practical nurse?

Show answer & explanation

Answer: Notify the registered nurse immediately of the client's changing status.

Answer

The priority action is to notify the registered nurse immediately of the client's changing status.
A feeling of neck tightness, restlessness, tachycardia, and hypotension following a thyroidectomy strongly indicate a developing hematoma or hemorrhage. This complication can rapidly compress the trachea and compromise the airway. The practical nurse must promptly report these critical findings to the registered nurse or healthcare provider to ensure rapid emergency intervention.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The client exhibits restlessness, a feeling of neck tightness, tachycardia, and a lowered blood pressure 4 hours post-thyroidectomy.
Identifying the onset of new or worsening symptoms is the first step in nursing assessment.
2
Recognize the physiological risk.
These symptoms are classic early indicators of hemorrhage or a developing neck hematoma, which can cause life-threatening airway obstruction.
Connecting postoperative symptoms to potential complications allows the nurse to prioritize interventions.
3
Determine the appropriate practical nursing action.
The practical nurse must immediately communicate these critical changes to the registered nurse or provider for emergency medical intervention.
Rapid escalation is required when a client shows signs of airway compromise or shock.

A practical nurse is reinforcing discharge instructions for a client who underwent a left cataract extraction earlier in the day. Which instruction regarding resting positions should the nurse provide to promote comfort and prevent complications?

Show answer & explanation

Answer: Sleep on your back with your head elevated or on your right side.

Answer

The client should sleep on their back with their head elevated, or on their unoperated (right) side.
Following a cataract extraction, it is critical to prevent any increase in intraocular pressure (IOP). Resting in a semi-Fowler's position (with the head elevated) utilizes gravity to promote fluid drainage away from the head, effectively lowering IOP. Sleeping on the unoperated (right) side prevents direct mechanical pressure from being applied to the surgical eye.

Step-by-Step Solution

1
Identify the surgical procedure and the affected side.
The client had a left cataract extraction.
Determining the operative side is necessary to protect the surgical site from physical pressure.
2
Determine the primary physiological goals for post-operative eye care.
The goals are to prevent increased intraocular pressure (IOP) and avoid direct trauma to the eye.
Elevated IOP or physical pressure can disrupt the surgical incision and compromise healing.
3
Select the resting position that best achieves these physiological goals.
Elevating the head of the bed and resting on the unoperated (right) side.
Gravity aids in lowering IOP when the head is elevated, and the right side-lying position keeps all physical pressure off the left eye.

A practical nurse (PN) is preparing to administer a scheduled dose of oral amoxicillin to a 3-year-old toddler weighing 15 kg15\text{ kg} who was admitted with a severe respiratory infection. Which of the following actions demonstrate safe pharmacological practice by the PN? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Verifying the toddler's identity by having the parent state the child's full name and date of birth.; Scanning the medication barcode and the toddler's identification band prior to dispensing the dose.; Withholding the scheduled dose and notifying the registered nurse (RN) after observing a new urticarial rash.

Answer

The correct actions include verifying the child's identity with the parent, utilizing barcode scanning for the medication and ID band, and withholding the medication if an allergic rash is noted.
Safe pharmacological practice requires strict adherence to the rights of medication administration and practicing within the legal scope. Verifying a pediatric client's identity through a parent and utilizing barcode scanning prevent identification errors. Furthermore, recognizing signs of a hypersensitivity reaction, such as an urticarial rash, and properly withholding the drug while notifying the RN demonstrates sound clinical judgment.

Step-by-Step Solution

1
Evaluate each action against the standard rights of medication administration.
Verifying identity with the parent and scanning barcodes directly support the 'right client' and 'right medication' checks.
Ensuring proper identification prevents medication errors, especially in pediatric populations.
2
Assess the clinical findings and the practical nurse (PN) scope of practice for each scenario.
Withholding the drug for a rash is a safe, necessary action. Administering an IV push medication is out of scope.
The PN must recognize signs of adverse reactions and operate strictly within defined legal boundaries.
3
Analyze the procedural and calculation methods described in the distractors.
Converting kilograms to pounds for a weight-based dose is incorrect, and leaving medications at the bedside violates administration protocols.
Standard pediatric dosing relies on kilogram measurements, and direct observation of ingestion is mandatory for safety.

An older adult client is resting in a surgical recovery unit two hours after a right-sided cataract extraction with intraocular lens implantation. The client requests assistance with morning hygiene, getting dressed, and finding a comfortable resting position. Which basic care actions should the nurse implement? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Elevate the head of the client's bed to 30 to 45 degrees.; Wash the client's face using a damp cloth, strictly avoiding the right eye area.; Provide increased oral fluids and high-fiber foods when preparing the client's meals.

Answer

The correct basic care actions are elevating the head of the bed, washing the face while avoiding the operative eye, and providing high-fiber foods with increased fluids.
Safe basic care post-cataract surgery requires minimizing intraocular pressure. Elevating the head of the bed facilitates venous drainage from the head. Washing the face carefully maintains hygiene while preventing surgical site trauma. Increasing fluids and fiber prevents constipation, ensuring the client does not strain during elimination.

Step-by-Step Solution

1
Analyze the client's surgical procedure (right-sided cataract extraction) and identify the primary physiological risk.
The primary risk during post-operative basic care is an increase in intraocular pressure (IOP) or direct trauma to the operative site.
Understanding the surgical risk dictates which standard comfort and hygiene measures are safe and which are contraindicated.
2
Evaluate the positioning and mobility options against the risk of increasing IOP.
Elevating the head of the bed decreases IOP, while lying on the operative side or bending at the waist dangerously increases IOP.
Gravity affects venous drainage from the head; proper positioning utilizes gravity to maintain normal ocular pressure.
3
Evaluate hygiene and nutritional basic care measures.
Washing around the eye without touching it prevents infection. High-fiber diets prevent straining (Valsalva maneuver), which would otherwise spike IOP.
Routine basic care must be modified to prevent secondary complications related to the surgical site.

Key Concept

Basic care and comfort measures following intraocular surgery must prioritize the prevention of increased intraocular pressure (IOP) through proper body mechanics, correct resting positions, and avoidance of straining.

A practical nurse (PN) is caring for an older adult client who has a history of heart failure, asthma, and gastroesophageal reflux disease. The PN is reviewing the medication administration record. Which actions by the PN demonstrate safe pharmacological practice? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Administering the prescribed short-acting bronchodilator inhaler 5 minutes before the corticosteroid inhaler.; Withholding the scheduled oral digoxin and alerting the registered nurse (RN) after auscultating an apical pulse of 54 beats per minute.; Rotating the application site of the transdermal nitroglycerin patch and cleansing the skin prior to placement.

Answer

The correct actions are to administer the bronchodilator before the corticosteroid, withhold digoxin for a heart rate below 60 bpm, and rotate transdermal patch sites.
The correct actions prioritize safety and adhere to the practical nurse's scope of practice. Administering a bronchodilator before a corticosteroid opens the airways for optimal absorption of the second medication. Withholding digoxin for bradycardia (apical pulse less than 60 beats per minute) and notifying the RN is crucial to prevent digoxin toxicity. Rotating transdermal patch sites and applying them to clean skin prevents skin irritation and ensures consistent medication absorption.

Step-by-Step Solution

1
Analyze the client's clinical data and prescribed medications.
The client has asthma, heart failure, and GERD, requiring multiple medications with specific administration protocols and safety checks.
Understanding the clinical context is essential for safe medication administration.
2
Evaluate the respiratory medication administration.
The bronchodilator must be given 5 minutes before the corticosteroid to open airways, allowing better absorption of the second medication.
This maximizes the therapeutic effect of the inhaled medications.
3
Evaluate the cardiovascular medication administration.
Digoxin must be withheld for an apical pulse below 60 beats per minute, and transdermal patches require site rotation. Furosemide should not be given with severe hypokalemia (2.8 mEq/L).
These actions prevent medication toxicity, skin breakdown, and severe adverse cardiovascular events.
4
Evaluate general medication safety and delegation.
Two proper unique identifiers are required (room number is invalid), and IV push medications are outside the standard PN scope of practice.
Ensuring the correct patient and staying within scope prevents sentinel events.
