Question 1881Question →

A practical nurse is assisting a female client in collecting a clean-catch midstream urine specimen for a culture and sensitivity test. Arrange the steps of the procedure in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with hand hygiene and gloving, followed by cleansing the meatus, initiating the urine stream into the toilet, collecting the midstream sample in the cup, and finally securing the container lid.
To collect an uncontaminated clean-catch urine specimen, the nurse must first perform hand hygiene and don gloves. Next, the perineal area is cleansed from front to back to remove surface bacteria. The client is then instructed to void a small amount into the toilet to flush the urethra. The sterile container is placed in the active urine stream to catch the sample. Finally, the lid is secured tightly without touching the inside to maintain specimen sterility.

Step-by-Step Solution

1
Identify the primary goal of the diagnostic collection procedure.
The goal is to obtain an uncontaminated urine sample for culture and sensitivity testing.
Understanding the goal highlights the importance of asepsis throughout the procedure.
2
Determine the initial preparatory safety steps.
Hand hygiene and applying clean gloves are the universal first steps to protect both the client and the nurse.
Standard precautions must precede any direct client contact or specimen collection.
3
Sequence the client-specific collection steps to prevent contamination.
The meatus is cleansed front to back, then the client voids a small amount to flush the urethra, and the midstream sample is collected.
This specific sequence prevents external gastrointestinal and vaginal bacteria from entering the sterile container.
4
Identify the concluding step to secure the specimen.
Securing the lid without touching the inside of the cup.
This maintains the sterility of the collected sample until it is transported to the laboratory.

Key Concept

Proper technique for clean-catch midstream urine specimen collection to prevent contamination.
Question 1882Question →

During morning medication rounds, a practical nurse (PN) approaches an alert and oriented client to give them their daily oral antibiotic. What is the most appropriate action for the PN to take to verify the client's identity prior to administration?

Show answer & explanation

Answer: Ask the client to state their full name and date of birth while comparing this information to the identification band and medication administration record.

Answer

The most appropriate action is to ask the client to explicitly state their full name and date of birth while verifying this against the identification band and official records.
The correct action directly adheres to standard medication administration safety principles. Using two distinct, acceptable patient identifiers (such as full name and date of birth) and having an alert client actively state their information while the nurse cross-references it with the ID band and MAR is the gold standard for preventing medication errors.

Step-by-Step Solution

1
Identify the standard protocol for safe medication administration regarding patient identification.
The standard protocol requires the use of at least two acceptable, distinct patient identifiers before administering any medication.
This fundamental safety check prevents medication errors and ensures the right drug goes to the right patient.
2
Evaluate each option based on the criteria for two acceptable identifiers and active client participation.
Asking the client to state their name and date of birth fulfills both criteria safely. The other methods rely on invalid identifiers like room numbers or passive verification.
Active verification (having the client speak their details) combined with official document checks (ID band and MAR) is the most reliable method for an alert client.

Question 1883Question →

A client on an inpatient psychiatric unit begins pacing rapidly near the medication room, clenching their fists, and shouting loudly. In what order should the practical nurse implement the following interventions? Arrange the actions in the correct sequence, starting with the immediate priority and progressing from least restrictive to most restrictive.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first secure the milieu by moving other clients, then attempt verbal de-escalation, offer voluntary oral medication, call for the behavioral response team, and finally, administer an intramuscular medication only as a last resort.
When managing an escalating behavioral crisis, the nurse must prioritize safety and follow the principle of least restrictive intervention. The first priority is always the safety of bystanders and the milieu, which requires removing other clients from the area. Next, the nurse must attempt the least invasive direct intervention, which is verbal de-escalation. If this is ineffective, offering a voluntary, oral medication is the next appropriate step. If the client continues to escalate and poses a threat, the nurse should call for a behavioral response team (a show of support). Finally, administering an intramuscular medication is considered a chemical restraint and is reserved as a last resort for imminent danger.

Step-by-Step Solution

1
Direct other clients in the vicinity to move to a safe, quiet area.
The immediate environment is secured.
Protecting the safety of other clients is the absolute first priority in any behavioral emergency.
2
Attempt verbal de-escalation using a calm, non-confrontational tone of voice.
The nurse attempts to calm the client using communication.
Verbal intervention is the least restrictive, non-invasive method to address agitation.
3
Offer the client a prescribed as-needed (PRN) oral medication for agitation.
The client is given a choice to take medication voluntarily.
If verbal methods fail, a voluntary oral medication is the next step in the least restrictive hierarchy.
4
Activate the facility's behavioral emergency response team.
Trained staff arrive to provide a show of support and manage potential violence.
When the client continues to escalate despite less restrictive measures, additional specialized assistance is necessary to maintain safety before applying physical or chemical restraints.
5
Administer a prescribed as-needed (PRN) intramuscular (IM) antipsychotic medication.
The client receives an involuntary or rapid-acting injectable medication.
IM medications for agitation act as a chemical restraint and are considered highly restrictive; they are used only when the client poses an imminent physical threat to self or others.

Question 1884Question →

During morning rounds, a practical nurse (PN) evaluates a client with cirrhosis and hepatic encephalopathy who is prescribed oral lactulose and oral spironolactone. The electronic health record reveals a morning serum potassium level of 2.8 mEq/L. The client currently exhibits bilateral asterixis and reports having three soft bowel movements over the past 12 hours. Which action should the PN take first?

Show answer & explanation

Answer: Withhold the scheduled lactulose dose and immediately report the serum potassium results to the supervising registered nurse (RN)

Answer

The correct action is to withhold the scheduled lactulose dose and immediately report the critical serum potassium results to the supervising registered nurse.
The client's potassium level of 2.8 mEq/L is critically low. Because lactulose induces osmotic diarrhea to eliminate ammonia, it inherently causes additional potassium loss through the gastrointestinal tract. Administering lactulose in the presence of severe hypokalemia places the client at imminent risk for lethal cardiac dysrhythmias. Furthermore, hypokalemia directly increases renal ammonia production, which ultimately worsens hepatic encephalopathy. The safest and most appropriate action within the practical nurse's scope of practice is to withhold the medication and immediately escalate the critical laboratory finding to the registered nurse for urgent intervention.

Step-by-Step Solution

1
Analyze the clinical laboratory data and physical assessment findings
The serum potassium is 2.8 mEq/L (critical hypokalemia). Asterixis is present (indicating active encephalopathy). Three soft stools indicate the lactulose is effectively increasing bowel motility.
Establishing the client's baseline physiological status is required before administering high-risk medications.
2
Evaluate the pharmacological mechanism and adverse effects of lactulose
Lactulose acts as an osmotic laxative to trap and excrete ammonia in the stool; however, this mechanism inherently causes significant gastrointestinal loss of water and electrolytes, specifically potassium.
Understanding the mechanism of action highlights the direct conflict between the medication's effect and the client's current potassium deficit.
3
Synthesize the physiological risks
Administering lactulose will worsen the severe hypokalemia, placing the client at imminent risk for lethal cardiac dysrhythmias. Additionally, severe hypokalemia actually increases renal ammonia production, paradoxically worsening the encephalopathy.
Clinical judgment requires balancing the therapeutic need (treating encephalopathy) against immediate life-threatening physiological risks (cardiac dysrhythmia from hypokalemia).
4
Determine the appropriate intervention within the PN scope of practice
The PN must withhold the unsafe medication and urgently escalate the critical potassium value to the RN for medical intervention.
A PN cannot independently alter medical prescriptions, but has a duty to withhold harmful medications and report critical findings.

Key Concept

Recognizing severe hypokalemia as an absolute contraindication for administering osmotic laxatives, and adhering to the PN scope of practice by withholding the drug and escalating critical labs.
Question 1885Question →

A practical nurse is reviewing data collected from various pediatric clients in a community clinic. Arrange the following observed client behaviors in the chronological order they are expected to developmentally emerge, from earliest (youngest) to latest (oldest).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence from earliest to latest is: the client looking for the dropped rattle (infancy), the client stating the stuffed dog is crying (early childhood/preschool), the client recognizing the liquid amount is unchanged (school-age), and finally the client discussing hypothetical future scenarios (adolescence).
Cognitive development follows a predictable chronological sequence from infancy through adolescence. Object permanence (searching for a hidden object) develops first in the sensorimotor stage. Animism (giving life to inanimate objects) follows in the preoperational stage. Conservation (understanding volume is independent of container shape) develops in the concrete operational stage. Finally, abstract and hypothetical reasoning emerges in the formal operational stage.

Step-by-Step Solution

1
Analyze the behavior of looking for a dropped rattle.
This indicates object permanence, which occurs in infancy (sensorimotor stage, approx. 8-12 months).
Infants learn that objects continue to exist even when they cannot be seen.
2
Analyze the behavior of attributing human emotions to a stuffed animal.
This indicates animism, which occurs in toddlerhood and preschool years (preoperational stage, approx. 2-7 years).
Young children often believe inanimate objects have lifelike qualities.
3
Analyze the behavior of understanding that the volume of liquid remains constant regardless of container shape.
This indicates conservation, which occurs in school-aged children (concrete operational stage, approx. 7-11 years).
School-aged children develop logical thought processes related to concrete, physical reality.
4
Analyze the behavior of discussing hypothetical future scenarios.
This indicates abstract reasoning, which occurs in adolescence (formal operational stage, 12+ years).
Adolescents can think abstractly and formulate theoretical outcomes.
5
Sequence the stages from youngest to oldest.
The correct sequence is object permanence (infant) -> animism (preschooler) -> conservation (school-aged) -> abstract reasoning (adolescent).
This follows Piaget's chronological stages of cognitive development.

Question 1886Question →

A community hospital activates its mass casualty disaster plan following a structural collapse at a nearby stadium. The triage center is receiving a high volume of victims, and the charge nurse is distributing client assignments among the healthcare team. Which client assignment is most appropriate for the practical nurse (PN) to accept?

Show answer & explanation

Answer: A client designated with a green tag who requires wound cleansing and a sterile dressing application for a forearm laceration.

Answer

The assignment involving the green-tagged client who needs a sterile dressing application for a forearm laceration.
In a mass casualty incident, clients with green tags have minor injuries and are considered clinically stable. Wound cleansing and sterile dressing changes fall within the established scope of practice for a practical nurse (PN), as this involves a predictable outcome and standard procedural care on a stable client. The PN can safely and independently manage this assignment.

Step-by-Step Solution

1
Evaluate the stability and acuity of each client based on their disaster triage tag.
Red indicates immediate life-threatening injury, yellow indicates delayed but potentially serious injury, black indicates expectant/dying, and green indicates a minor 'walking wounded' injury.
Prioritization in disaster triage determines the level of care and immediacy required.
2
Analyze the specific nursing interventions required for each client.
The tasks include respiratory assessment, baseline neurological evaluation, IV push medication administration, and a sterile dressing change.
Delegation must accurately align with the complexity of the required task and the client's current clinical stability.
3
Match the required tasks and client stability to the practical nurse (PN) scope of practice.
Initial assessments (respiratory and neurological) and IV push medications are outside the PN scope. A sterile dressing change on a stable client is well within the PN scope.
Safe delegation mandates that PNs only accept assignments involving stable clients with predictable outcomes requiring standard procedures.

Question 1887Question →

A male client who observes the Islamic holy month of Ramadan is recovering from an abdominal procedure on a medical-surgical unit. The care plan requires an extensive, painful wound packing change twice daily. When the LPN/LVN brings the scheduled morning oral analgesic, the client declines the medication, explaining that his religious fasting prohibits all oral intake from dawn to sunset. What is the priority nursing action?

Show answer & explanation

Answer: Collaborate with the registered nurse (RN) to reschedule the wound care to the evening hours after the client has broken his fast and taken the analgesic.

Answer

Collaborate with the registered nurse (RN) to reschedule the wound care to the evening hours after the client has broken his fast and taken the analgesic.
During Ramadan, observant Muslims abstain from all food, liquid, and oral medications from dawn until sunset. The correct action is to advocate for the client's spiritual practices by collaborating with the RN to adjust the care schedule. This allows the client to take their pain medication after sunset, ensuring the painful procedure is performed when the analgesia is fully effective without violating their religious beliefs.

Step-by-Step Solution

1
Assess the client's stated religious need and the clinical requirement for pain management.
The client cannot take oral medications during daylight hours due to Ramadan fasting, but requires analgesia for a painful wound packing procedure.
Understanding the conflict between the standard medication schedule and the client's spiritual practice is the first step in culturally competent care.
2
Identify available nursing interventions that accommodate the spiritual belief without compromising patient safety or comfort.
The timing of the dressing change can be adjusted.
Nursing care should be individualized. Routine procedures can often be shifted to align with a client's cultural or spiritual needs.
3
Collaborate with the RN and interdisciplinary team to update the care plan.
The wound care and medication administration are safely rescheduled to the evening.
The LPN/LVN must work within their scope of practice by collaborating with the RN to modify the established care plan.

Question 1888Question →

During the morning medication pass on an inpatient psychiatric unit, a client with schizophrenia pushes the medication cup away. The client states, "I cannot swallow those. The voices warned me that they are filled with poison." Which response by the practical nurse (PN) is most therapeutic?

Show answer & explanation

Answer: It sounds very frightening to hear that. I do not hear the voices, but this is your prescribed medication.

Answer

The most therapeutic response validates the client's fear, presents reality regarding the hallucinations, and states the factual nature of the medication.
The correct response effectively uses three therapeutic techniques: expressing empathy for the client's fear, presenting reality by clarifying that the nurse does not hear the voices, and offering information about the medication. This approach maintains safety and trust without reinforcing the psychosis.

Step-by-Step Solution

1
Analyze the client's behavior and statements.
The client is experiencing active auditory hallucinations and a paranoid delusion about the medication being poisoned.
Identifying the psychiatric symptoms guides the selection of the appropriate communication technique.
2
Recall therapeutic communication principles for clients with hallucinations and delusions.
The nurse should acknowledge the client's feelings, present reality without arguing, and avoid validating the delusion.
Arguing with a delusion is ineffective, while validating the underlying emotion builds trust.
3
Evaluate the options against non-therapeutic communication blocks.
Eliminate options that ask 'why', argue with logic, provide false reassurance, or use threats.
These blocks escalate anxiety and damage the therapeutic relationship.

Question 1889Question →

A healthcare provider prescribes levothyroxine 0.05 mg0.05\text{ mg} orally once daily for a client managed for hypothyroidism. The medication drawer contains levothyroxine 25 mcg25\text{ mcg} tablets. How many tablets should the practical nurse administer for the scheduled dose? Record the answer as a whole number. Do not include units in the answer.

Show answer & explanation

Answer: 2

Answer

The practical nurse should administer 2 tablets.
To safely calculate the dose, the prescribed amount (0.05 mg0.05\text{ mg}) must first be converted to the same unit as the available medication (25 mcg25\text{ mcg} tablets). Multiplying 0.05 mg0.05\text{ mg} by 10001000 yields 50 mcg50\text{ mcg}. Using the standard formula (Desired divided by Have), 50 mcg50\text{ mcg} divided by 25 mcg25\text{ mcg} equals 22 tablets.

Step-by-Step Solution

1
Convert the prescribed dose to match the unit of the available medication.
0.05 mg=50 mcg0.05\text{ mg} = 50\text{ mcg}
Safe medication administration requires calculations to be performed using the same unit of measurement.
2
Calculate the number of tablets using the standard dosage formula.
50 mcg25 mcg×1 tablet=2 tablets\frac{50\text{ mcg}}{25\text{ mcg}} \times 1\text{ tablet} = 2\text{ tablets}
This determines the exact physical quantity to administer to the client to achieve the prescribed dose.

Question 1890Question →

A client with dysphagia receives continuous enteral feedings via a nasogastric (NG) tube. The healthcare provider has ordered two distinct liquid medications to be given via the tube. After pausing the feeding pump, in what sequence should the practical nurse (PN) execute the following actions to safely deliver these medications?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with positioning the client, verifying tube placement, performing an initial water flush, administering the first medication via gravity, performing an intermediate flush, and finally administering the second medication followed by a terminal flush.
Safe administration of medications via an enteral tube requires strict adherence to sequential safety checks. Elevating the head of the bed minimizes aspiration risk. Verifying placement ensures the tube has not migrated to the lungs. Flushing before, between, and after medications verifies patency, prevents drug-nutrient/drug-drug incompatibilities, and ensures the full dose reaches the stomach. Gravity administration prevents excessive pressure that could rupture the tube.

Step-by-Step Solution

1
Elevate the head of the bed.
The client is safely positioned at 30 degrees or higher.
Reduces the risk of pulmonary aspiration during the medication administration process.
2
Verify tube placement and check residual.
Gastric placement is confirmed, ensuring safety.
Guarantees medications will enter the gastrointestinal tract and not the respiratory system.
3
Perform the initial water flush.
The tube is cleared of formula and patency is established.
Prevents drug-nutrient interactions and ensures the tube is unblocked.
4
Administer the first medication via gravity.
The first dose enters the stomach safely.
Gravity flow prevents excess pressure, while administering one medication at a time avoids drug interactions.
5
Flush with 15 to 30 mL of water.
The tube is cleared of the first medication.
Prevents drug-drug interactions or precipitation inside the tube when multiple medications are ordered.
6
Administer the second medication and the final flush.
All medications are delivered and the tube is thoroughly cleared.
Ensures complete dosing and maintains long-term tube patency.

Question 1891Question →

During a routine wellness visit, the parent of a 10-year-old female client privately expresses concern to the practical nurse. The parent states, "I felt a small, firm, and slightly tender lump directly beneath her left nipple, but the right side is completely flat." Based on the knowledge of normal developmental stages, which conclusion should the practical nurse draw from this information?

Show answer & explanation

Answer: The client is experiencing an expected physiological transition signaling the initial stages of puberty.

Answer

The client is experiencing an expected physiological transition signaling the initial stages of puberty.
Thelarche, or breast budding, is typically the first physical sign of puberty in females and normally occurs between 8 and 13 years of age. It is highly common for this development to begin unilaterally and present as a firm, slightly tender mass under the areola. Recognizing this as a normal physiological transition allows the nurse to provide appropriate anticipatory guidance and reassurance to the parent, preventing unnecessary diagnostic testing or anxiety.

Step-by-Step Solution

1
Analyze the client's age and sex in relation to developmental milestones.
The client is a 10-year-old female, entering the expected age range for pubertal transitions.
Age and sex are critical determinants for evaluating the appropriateness of physical changes.
2
Evaluate the specific clinical finding described by the parent.
A firm, slightly tender, unilateral lump under the nipple is noted.
Identifying the characteristics of the finding helps differentiate between normal growth and pathology.
3
Correlate the finding with normal pediatric developmental transitions.
The finding is consistent with thelarche (breast budding), which normally occurs between ages 8 and 13.
Thelarche is often the first sign of puberty, frequently begins unilaterally, and can be accompanied by mild tenderness, which is a normal transition rather than a disease process.

A practical nurse (PN) is reviewing the electronic health record for a client with heart failure who is prescribed digoxin 0.25 mg0.25\text{ mg} PO and furosemide 40 mg40\text{ mg} PO daily. Morning assessment data reveals an apical pulse of 54 beats/min54\text{ beats/min} and a serum potassium level of 2.8 mEq/L2.8\text{ mEq/L}. Which action should the PN take?

Show answer & explanation

Answer: Withhold both medications and immediately escalate the assessment findings to the registered nurse (RN).

Answer

The PN must withhold both the digoxin and the furosemide and immediately escalate the assessment findings to the registered nurse (RN).
The correct action is to withhold both medications. Digoxin requires an apical pulse of at least 60 beats/min60\text{ beats/min} for safe administration; the client's pulse is 54 beats/min54\text{ beats/min}. Furosemide is a loop diuretic that wastes potassium; administering it to a client with a critically low potassium level of 2.8 mEq/L2.8\text{ mEq/L} would dangerously worsen the hypokalemia. Furthermore, hypokalemia increases the risk of digoxin toxicity. The PN must withhold the doses and report these critical findings to the RN immediately.

Step-by-Step Solution

1
Evaluate the client's vital signs against medication administration parameters.
The apical pulse is 54 beats/min54\text{ beats/min}, which is below the standard 60 beats/min60\text{ beats/min} threshold for administering digoxin.
Digoxin has a negative chronotropic effect (slows heart rate). Giving it during bradycardia can lead to severe cardiac compromise.
2
Analyze the laboratory results in the context of the prescribed medications.
The serum potassium is 2.8 mEq/L2.8\text{ mEq/L} (normal is 3.53.5 to 5.0 mEq/L5.0\text{ mEq/L}). Furosemide is a loop diuretic that causes potassium loss.
Administering furosemide will exacerbate the severe hypokalemia, which can trigger fatal dysrhythmias.
3
Synthesize the interaction between the laboratory findings and digoxin.
Hypokalemia increases myocardial sensitivity to digoxin.
Even at normal dosage levels, low potassium increases the risk of digoxin toxicity.
4
Determine the appropriate nursing intervention within the PN scope of practice.
The PN must withhold both contraindicated medications and escalate the critical findings to the RN or provider.
Operating safely within the PN scope requires recognizing abnormal data, withholding harmful interventions, and communicating with the supervising RN.

Key Concept

Pharmacological safety involves synthesizing vital signs, laboratory data, and drug interactions to recognize critical administration contraindications.
Question 1893Question →

A practical nurse is assigned to a home healthcare visit to observe a 6-month-old infant's progress. As the infant interacts with the environment, which finding should the nurse recognize as a developmental delay that must be reported to the supervising registered nurse?

Show answer & explanation

Answer: The infant's head falls backward when pulled from a supine to a seated position.

Answer

The infant's head falling backward when pulled from a supine to a seated position indicates a developmental delay.
By 4 months of age, an infant should have established head control with no head lag when pulled to a sitting position. The presence of a head lag at 6 months is a significant red flag for a gross motor or neurological delay and must be reported immediately.

Step-by-Step Solution

1
Analyze the client's current chronological age.
The infant is exactly 6 months old.
Developmental milestones are evaluated based on chronological age to determine expected versus delayed progress.
2
Evaluate the motor, psychosocial, and language findings presented in the options against expected 6-month milestones.
Palmar grasp, stranger anxiety, and babbling are normal developmental findings at 6 months. Pronounced head lag is abnormal.
Differentiating between expected transitions and genuine delays is essential for safe practical nursing care.
3
Identify the specific finding that requires reporting.
Head lag at 6 months requires intervention because infants should have full head control by 4 months of age.
Identifying missing milestones allows the nurse to promptly report the deviation to the supervising RN for further provider evaluation.

Key Concept

Normal infant developmental milestones and identification of developmental delays.
Question 1894Question →

A practical nurse in a pediatric clinic is reviewing the health histories of four clients scheduled for routine well-child visits. Which finding requires the nurse to collaborate with the registered nurse to modify the client's preventive care plan?

Show answer & explanation

Answer: A 4-month-old infant scheduled for the rotavirus vaccine who has a documented history of intussusception

Answer

A 4-month-old infant scheduled for the rotavirus vaccine who has a documented history of intussusception
The rotavirus vaccine is an orally administered live-attenuated vaccine that carries a small risk of intussusception (a medical emergency where the bowel telescopes into itself). A previous history of intussusception is an absolute contraindication to receiving this vaccine. The practical nurse must recognize this and collaborate with the registered nurse or healthcare provider to cancel the rotavirus vaccine order.

Step-by-Step Solution

1
Evaluate the 12-month-old infant's developmental milestone.
Not walking independently at 12 months is within the normal developmental timeframe (typically 12-15 months).
To determine if a developmental delay exists that requires intervention.
2
Analyze the immunization orders against the clients' medical histories.
The rotavirus vaccine is contraindicated for the infant with a history of intussusception.
Administering the rotavirus vaccine to an infant with prior intussusception increases the risk of a recurrent bowel telescoping emergency.
3
Assess the nutritional adequacy of a lacto-vegetarian diet for a 3-year-old.
This diet includes dairy and can meet the child's nutritional needs; it is a safe cultural practice.
To differentiate between a dietary risk and a safe cultural preference.

Question 1895Question →

A practical nurse is reviewing clinical data for multiple clients in the postpartum care area. Which finding represents the most critical physiological risk that must be reported to the registered nurse immediately?

Show answer & explanation

Answer: A client who gave birth 8 hours ago with a resting pulse that has gradually increased from 74 to 116 beats per minute

Answer

The client who gave birth 8 hours ago with a resting pulse that has gradually increased from 74 to 116 beats per minute.
The correct answer identifies a client exhibiting a subtle, early sign of postpartum hemorrhage and compensatory shock. Because pregnant individuals have an expanded blood volume, blood pressure often remains stable until significant blood loss occurs. Therefore, a gradually increasing resting heart rate is a critical finding that requires immediate escalation to the registered nurse for a comprehensive assessment of uterine tone, fundal height, and fluid volume status.

Step-by-Step Solution

1
Analyze the vital sign trends for the client who gave birth 8 hours ago.
The resting heart rate has escalated from a baseline of 74 to 116 beats per minute.
An increasing heart rate (tachycardia) is the earliest compensatory mechanism for hypovolemia and a primary indicator of postpartum hemorrhage before blood pressure drops.
2
Evaluate the neonate's respiratory assessment.
The neonate exhibits pauses up to 12 seconds.
This is recognized as periodic breathing, a normal neonatal finding, as true apnea involves pauses longer than 20 seconds or is associated with color changes.
3
Interpret the postpartum laboratory values.
The WBC count is 22,000 /mm322,000 \text{ /mm}^3.
This is an expected physiological elevation due to the stress of labor, not a critical sign of sepsis.
4
Assess the lochia volume over time.
One pad saturated over three hours is identified as moderate lochia.
This is an expected rate of bleeding 20 hours postpartum; it does not indicate hemorrhage.

Key Concept

Prioritization of early hemorrhagic shock indicators over expected postpartum and neonatal physiological adaptations.
Question 1896Question →

An older adult resident at a skilled nursing facility is participating in a scheduled physical therapy session following a total hip arthroplasty. After struggling to complete a walking exercise, the resident abruptly pushes the walker away, shouts at the practical nurse (PN), "You are all incompetent and making me worse!" and refuses to continue. Which actions should the PN take? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Remain present with the resident while maintaining a calm, non-threatening posture.; Recognize the resident's outburst as a manifestation of the displacement defense mechanism.; Notify the supervising registered nurse regarding the resident's escalating emotional distress and refusal of care.

Answer

The appropriate actions are to remain calmly present with the resident, recognize the behavior as the defense mechanism of displacement, and notify the supervising registered nurse.
The correct actions prioritize client safety, emotional support, and appropriate role delegation. Remaining calmly present provides support without escalating the situation. Recognizing the outburst as displacement helps the nurse maintain clinical objectivity rather than taking the insult personally. Finally, notifying the RN ensures the client's care plan can be properly reassessed by the healthcare team.

Step-by-Step Solution

1
Analyze the resident's coping behavior.
The resident is projecting anger about their physical limitations onto the staff, which identifies the use of displacement.
Understanding the psychological defense mechanism guides the nurse in formulating a therapeutic, non-judgmental response.
2
Determine the most appropriate therapeutic communication approach.
Remaining quietly present is therapeutic, whereas asking demanding questions or offering false reassurances will block communication.
A calm, silent presence supports a highly distressed client without provoking further escalation or defensiveness.
3
Apply the practical nursing scope of practice to the scenario.
The PN must report the escalating distress and therapy refusal to the RN, but cannot independently cancel the therapy orders.
Altering the multidisciplinary plan of care is outside the PN scope, but data collection and reporting are mandated responsibilities.

Key Concept

Therapeutic communication, coping mechanisms (displacement), and practical nursing scope of practice.
Question 1897Question →

A practical nurse (PN) is planning care for a client who is 48 hours postoperative following a right above-the-knee amputation. The client is receiving continuous enteral nutrition via a nasogastric tube and has a prescription to be placed in the prone position for 30 minutes twice daily. Which action should the PN take to safely implement this positioning requirement?

Show answer & explanation

Answer: Stop the continuous enteral feeding for 30 to 60 minutes before assisting the client into the prone position.

Answer

Stop the continuous enteral feeding for 30 to 60 minutes before assisting the client into the prone position.
The correct action demonstrates the ability to safely coordinate two conflicting care requirements. Prone positioning is essential to stretch the flexor muscles and prevent hip contractures following an above-the-knee amputation. However, placing a client flat while their stomach contains enteral formula creates a high risk for aspiration. By stopping the feeding 30 to 60 minutes beforehand, the nurse allows time for gastric emptying, protecting the airway while fulfilling the postoperative basic care prescription.

Step-by-Step Solution

1
Identify the primary clinical goals for this client.
The client needs prone positioning to prevent hip flexion contractures (post-amputation) and requires protection from aspiration due to continuous enteral feeding.
Recognizing competing physiological needs is the first step in prioritizing safe care.
2
Analyze the positioning requirements for both interventions.
Prone positioning requires the client to lie flat on their abdomen. Enteral feeding requires the head of the bed to be elevated at least 30 to 45 degrees.
Lying flat while receiving enteral feeds or immediately after feeding poses a severe aspiration risk.
3
Determine the appropriate sequencing of care.
The feeding must be paused in advance of the position change to allow for gastric emptying.
Stopping the feed 30 to 60 minutes prior ensures the stomach is relatively empty when the client is placed flat, adhering to ABC (Airway, Breathing, Circulation) prioritization while meeting basic care needs.

Staff at an adult day care center report that an 81-year-old participant, who is typically sociable and continent, is experiencing new-onset urinary incontinence and wandering aimlessly. The participant appears restless and repeatedly attempts to leave the building. Which of the following interventions should the practical nurse implement? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Check the client's vital signs and oxygen saturation levels.; Obtain a urine specimen for laboratory analysis as prescribed.; Relocate the client to a calm, low-stimulation environment with direct supervision.

Answer

The correct interventions are to check the client's vital signs, obtain a prescribed urine specimen, and relocate the client to a calm, supervised environment.
In the older adult population, acute infections (especially urinary tract infections) often present atypically with sudden confusion, incontinence, and behavioral changes collectively known as delirium. The practical nurse must prioritize identifying the underlying physiological cause by checking vital signs and obtaining lab specimens, while maintaining the client's safety through non-restrictive measures like a calm environment and direct supervision.

Step-by-Step Solution

1
Recognize atypical disease presentation in the older adult.
Identified that sudden onset of incontinence, restlessness, and wandering are hallmark signs of delirium rather than normal aging.
Older adults frequently exhibit acute confusion as the primary symptom of physiological stressors, such as infections.
2
Prioritize physiological assessment to find the reversible cause.
Selected checking vital signs, oxygen saturation, and obtaining a urine specimen.
Gathering objective data helps identify if a urinary tract infection, hypoxia, or other physiological disruption is causing the sudden behavioral shift.
3
Implement safety measures using the least restrictive interventions.
Selected relocating the client to a calm, low-stimulation environment with direct supervision.
Maintaining client safety is critical during an episode of delirium, but it must be achieved without resorting to physical or chemical restraints.

A severe storm has caused structural damage to a rehabilitation center, triggering the facility's internal disaster protocol. The healthcare team is rapidly relocating clients and organizing care. Which assignment is most appropriate for the licensed practical nurse (PN) to accept?

Show answer & explanation

Answer: Administering a prescribed intramuscular analgesic to a stable client who sustained a minor soft tissue injury.

Answer

The correct assignment is administering a prescribed intramuscular analgesic to a stable client who sustained a minor soft tissue injury.
The correct assignment represents safe, routine care for a stable client. The PN scope of practice includes administering intramuscular medications to clients with predictable outcomes. In a disaster scenario, delegating straightforward procedures to the PN maximizes team efficiency and allows the RN to focus on complex triage.

Step-by-Step Solution

1
Identify the context of the clinical scenario.
The facility is executing an internal disaster protocol due to severe structural damage.
Understanding the emergency context highlights the need for efficient and safe delegation of tasks according to strict scopes of practice.
2
Evaluate the acuity and stability of each client described in the options.
The clients in the incorrect options are either newly extracted, exhibiting signs of shock, or presenting an immediate physical threat.
Unstable clients, clients in an active behavioral crisis, or those requiring initial complex assessment must be managed by an RN or security personnel.
3
Determine the appropriate task for the practical nurse.
Administering IM medication to a stable client with a minor injury safely aligns with established PN capabilities.
Delegating routine, predictable care to the PN is standard emergency practice, allowing RNs to allocate their expertise to life-threatening situations.

Key Concept

During an internal disaster, the licensed practical nurse (PN) should be assigned to care for stable clients with predictable outcomes, allowing the registered nurse (RN) to manage triage, initial assessments, and unstable clients.

A practical nurse is caring for a client who returned to the medical-surgical unit one hour ago following a percutaneous liver biopsy. Which of the following interventions should the nurse include in the client's plan of care? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Maintain the client in a right side-lying position.; Place a small pillow or folded towel under the puncture site.; Offer the client a bedpan or urinal for elimination needs.

Answer

The correct interventions are to maintain the client in a right side-lying position, place a small pillow under the puncture site, and offer a bedpan for elimination.
The correct actions involve placing the client in a right side-lying position with a towel or small pillow under the puncture site to apply direct, localized pressure to the highly vascular liver. This physical pressure is critical to prevent hemorrhage. Furthermore, because the client must remain on strict bed rest for several hours to maintain this pressure, the nurse must assist with basic care by providing a bedpan or urinal for urinary elimination.

Step-by-Step Solution

1
Identify the primary risk associated with a percutaneous liver biopsy.
The liver is a highly vascular organ, making post-procedure hemorrhage the most significant complication.
Understanding the primary circulatory risk directs the choice of appropriate basic care and positioning interventions.
2
Determine the correct post-procedure positioning to address the risk.
The client must be placed in a right side-lying position with a pillow or towel under the right costal margin.
This specific positioning utilizes the client's own body weight to apply direct, localized pressure to the liver capsule, preventing bleeding.
3
Evaluate the remaining basic care needs based on activity restrictions.
Because the client is on strict bed rest to avoid dislodging the clot, the nurse must provide a bedpan or urinal for elimination rather than allowing ambulation.
Maintaining strict bed rest minimizes intra-abdominal pressure and protects the fragile clot at the puncture site.

Key Concept
