After receiving the morning report on a mixed acuity medical unit, the nurse must prioritize the initial assessments for four clients. Order the clients from the highest priority (first to be seen) to the lowest priority (last to be seen).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes the airway emergency first, followed by the metabolic emergency, then pain management, and finally the routine procedural task.
Prioritization in nursing strictly follows the ABCs (Airway, Breathing, Circulation) and Maslow's Hierarchy of Needs. The asthma client presents an immediate airway and breathing threat (highest priority). The diabetic client presents a circulation and metabolic threat (second priority). The pneumonia client has an acute but non-life-threatening comfort need (third priority). The cellulitis client requires a routine, stable task (lowest priority).

Step-by-Step Solution

1
Evaluate the clients using the Airway, Breathing, Circulation (ABC) framework.
The client with asthma who is restless and wheezing has an immediate airway and breathing compromise.
Airway and breathing issues are the most critical and life-threatening conditions.
2
Identify any urgent circulation or metabolic anomalies among the remaining clients.
The client with diabetes is exhibiting classic signs of acute hypoglycemia (tremors, diaphoresis).
Metabolic emergencies require rapid intervention to prevent severe neurological damage or coma.
3
Distinguish between urgent systemic needs and localized or routine needs.
The client with pneumonia needs pain relief, which is a priority over a routine dressing change, but less critical than a metabolic crisis.
Pain is an urgent physiological need but does not immediately threaten life in a stable client.
4
Assign the lowest priority to stable, scheduled, or routine tasks.
The client with cellulitis requiring a dressing change is placed last.
Routine interventions for stable conditions can be safely delayed.

Key Concept

Prioritization using the Airway, Breathing, Circulation (ABC) framework and acute vs. chronic condition analysis.

Question 282Question →

A pediatric nurse is educating a group of new parents about expected gross motor skill acquisition during the first year of life. Arrange the following gross motor developmental milestones in the chronological order in which they typically occur in a healthy infant, from earliest to latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of gross motor development is: lifting head and chest while prone, followed by rolling from abdomen to back, then sitting completely without support, and finally pulling up to a standing position.
Infant gross motor development strictly follows a cephalocaudal pattern, meaning control progresses from the head downward. Infants first gain control of their head and neck (lifting head prone), followed by their upper trunk (rolling over), then their lower back and core (sitting without support), and finally their lower extremities (pulling to a stand).

Step-by-Step Solution

1
Recall the directional pattern of infant motor development.
Motor development follows a cephalocaudal (head-to-toe) and proximodistal (center-to-periphery) pattern.
Understanding these developmental laws helps logically sequence milestones without pure memorization.
2
Identify the milestone involving the head and neck.
Lifting the head and chest while prone (2-3 months) is the earliest listed milestone.
Head control is the first major gross motor achievement.
3
Identify the milestone involving the torso.
Rolling from abdomen to back (4-5 months) occurs next as the infant gains truncal strength.
Truncal control develops after head control but before lower body control.
4
Identify the milestones involving core stability and the lower extremities.
Sitting without support (8 months) precedes pulling to a standing position (9-10 months).
An infant must have complete core and back stability to sit independently before they can bear weight on their legs to pull up.

Question 283Question →

A nurse is caring for a client with acute delirium who is repeatedly attempting to pull out a central venous catheter. Arrange the following nursing actions in the correct chronological sequence, progressing from the least restrictive initial intervention to the application and management of restraints.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: assess for underlying causes, implement non-restrictive alternatives, obtain a provider prescription, apply restraints safely to the movable bed frame, and document the intervention comprehensively.
The standard of care for safety devices requires a strict, stepwise approach. The nurse must first attempt to identify and resolve underlying causes of agitation. If this fails, least restrictive alternatives must be trialed. Only when alternatives are ineffective and the client poses an immediate risk to themselves can the nurse seek a provider's prescription for restraints. After applying the restraints safely, thorough documentation is legally and clinically mandated.

Step-by-Step Solution

1
Assess the client for underlying causes of agitation.
Identifies and potentially resolves reversible triggers for the behavior.
Basic nursing principles require addressing root causes (e.g., hypoxia, pain) before escalating to behavioral controls.
2
Implement non-restrictive safety alternatives.
Attempts to keep the client safe without limiting their physical freedom.
Legal and ethical standards mandate using the least restrictive environment possible to protect client autonomy.
3
Contact the healthcare provider for a restraint prescription.
Secures legal authorization to apply a safety device.
Restraints cannot be applied without a valid, time-limited provider order, confirming that the intervention is medically necessary.
4
Apply the restraints using a quick-release knot attached to the movable part of the bed frame.
Safely immobilizes the client's extremities to prevent tube dislodgement.
Securing to the movable frame prevents injury that could occur if the bed position is adjusted while tied to a fixed point.
5
Document the entire sequence of events.
Creates a legal and clinical record of compliance.
Regulatory bodies require strict documentation of the behaviors precipitating restraint use, the alternatives trialed, and the specific application details.

Key Concept

Prioritization of safety measures progressing from the least restrictive alternatives to the safe application and legal documentation of physical restraints.
Question 284Question →

A community health nurse is educating an adult client on how to perform an at-home guaiac-based fecal occult blood test (gFOBT) for colorectal cancer screening. Arrange the following steps for sample collection in the correct chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: 1) Collect the specimen in a clean container; 2) Open the testing card and obtain a smear; 3) Apply the smear to the first window; 4) Use a new stick to sample a different area for the second window; 5) Close the card and package it for transport.
For an at-home guaiac-based fecal occult blood test, following the correct chronological sequence ensures specimen integrity and accurate screening results. The stool must first be collected cleanly without water or urine contamination. Then, the client opens the card, takes a sample, and applies it to the first window. Crucially, a second sample from a different part of the stool must then be applied to the second window to maximize the chance of detecting hidden blood. Finally, the card is sealed and packaged for transport.

Step-by-Step Solution

1
Determine the initial preparation and collection method.
The client must first collect the specimen in a dry container without contaminating it with toilet water or urine.
Contamination with water or urine can invalidate the test, making proper collection the foundational step.
2
Identify the process for loading the first sample.
The client opens the flap, takes a smear, and applies it to the first window.
The card must be opened and the initial sample applied to begin the actual testing procedure.
3
Identify the process for loading the second sample.
The client uses a new stick to sample a completely different area of the stool for the second window.
Sampling different areas of the stool increases the chances of detecting intermittent or localized bleeding in the gastrointestinal tract.
4
Determine the final packaging and transport step.
The card is closed securely and placed in the provided envelope.
Proper sealing and packaging ensure the sample remains intact, uncontaminated, and safe for those handling the envelope during transport.

Question 285Question →

A nurse is caring for a client in the intensive care unit who is agitated and repeatedly attempting to remove their nasogastric (NG) tube. Arrange the following nursing interventions in the order they should be implemented, from least restrictive to most restrictive.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from least to most restrictive is: reorient the client, provide a diversionary activity (stress ball), conceal the tube out of sight, apply non-tethered hand mittens, and finally apply tethered soft limb restraints.
In nursing practice, the principle of the least restrictive environment mandates that non-physical and less restrictive interventions must be attempted and documented before applying mechanical restraints. The sequence correctly progresses from cognitive interventions (reorientation) to behavioral strategies (diversion), environmental modifications (concealing the tube), low-level physical barriers (mittens), and finally high-level physical restraints (tethered limb restraints).

Step-by-Step Solution

1
Identify the least restrictive, non-physical intervention.
Reorient the client to the environment and explain the necessity of the tube.
Verbal communication addresses potential confusion without restricting the client in any way.
2
Identify the next least restrictive behavioral intervention.
Provide the client with a stress ball to squeeze.
Diversionary activities keep the hands safely occupied without applying any physical barriers.
3
Identify an environmental modification that reduces triggers.
Secure the tube out of the client's immediate line of sight.
Removing the visual stimulus can decrease the urge to pull on the equipment.
4
Select the least restrictive physical device.
Place bilateral hand mittens that are not tethered to the bed.
Mittens prevent the fine motor skill of grasping the tube but allow the client to move their arms freely.
5
Identify the most restrictive physical intervention.
Apply soft limb restraints attached to the movable part of the bed frame.
Tethering the client's limbs to the bed severely restricts movement and is only used when all other alternatives fail.

Question 286Question →

A nurse has finished providing care for a client requiring airborne and contact precautions. The nurse is wearing an N95 respirator, a face shield, an isolation gown, and gloves. Arrange the following steps for safely removing (doffing) the personal protective equipment (PPE) in the correct chronological order according to standard infection control guidelines.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for doffing PPE is: Gloves, Face Shield, Gown, N95 Respirator, and finally Hand Hygiene.
The standard CDC sequence for removing PPE is specifically designed to prevent cross-contamination from the most soiled items to the healthcare worker's body. Gloves are removed first because they are typically the most contaminated, followed by the face shield to protect the mucous membranes. The gown is removed next, and the N95 respirator is removed last (typically outside the patient room) to ensure the airway remains continuously protected from airborne pathogens. Finally, hand hygiene is performed to eliminate any remaining pathogens.

Step-by-Step Solution

1
Remove gloves
Hands are freed from the most contaminated PPE without soiling the skin.
Gloves are heavily contaminated; removing them first prevents the transfer of pathogens to the face or neck during subsequent steps.
2
Remove face shield
Eye protection is safely removed.
Handling only the clean headband prevents hand contamination while protecting the eyes from the soiled front of the shield.
3
Remove gown
Body protection is removed and contained.
Rolling the gown inside-out traps contaminants inside, protecting the uniform and the surrounding environment.
4
Remove N95 respirator
Respiratory protection is removed safely.
The respirator is kept on until the very end to prevent the inhalation of airborne particles while removing the rest of the PPE.
5
Perform hand hygiene
Hands are completely clean and safe.
This mandatory final step ensures that any incidental contamination transferred during the doffing process is completely eliminated.

Key Concept

Standard chronological sequence for doffing personal protective equipment to minimize cross-contamination.
Question 287Question →

A nurse is caring for a client receiving internal radiation therapy (brachytherapy) for cervical cancer. Upon entering the room, the nurse discovers that the sealed radiation implant has dislodged and is lying on the bed linens. Arrange the following nursing actions in the correct sequence of execution.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first instruct the client to remain still, followed by retrieving the source with long-handled forceps, placing it in the lead container, securing the lid, and finally notifying the appropriate personnel.
When a sealed radiation source (brachytherapy implant) becomes dislodged, the primary goal is to safely contain the hazard while minimizing radiation exposure to the client and staff. The nurse must first instruct the client to remain completely still to prevent the implant from falling to the floor or becoming difficult to locate. Next, utilizing the principle of distance, the nurse uses long-handled forceps to retrieve the source. The principle of shielding is then applied by immediately placing the implant into the designated lead-lined container and securing the lid. Once the immediate hazard is safely contained, the nurse must notify the Radiation Safety Officer and the healthcare provider for further evaluation and intervention.

Step-by-Step Solution

1
Prevent further movement of the source.
Instruct the client to lie completely still.
Minimizes the risk of the source falling onto the floor or becoming entangled, which complicates retrieval and increases exposure time.
2
Safely pick up the radioactive material.
Retrieve the radioactive source using long-handled forceps.
Maximizes distance from the radioactive material, reducing radiation exposure to the nurse in accordance with the ALARA (As Low As Reasonably Achievable) principle.
3
Provide shielding from the radiation.
Place the implant into the designated lead-lined container.
Lead blocks radiation emission, protecting the client and staff from further environmental exposure.
4
Secure the radiation source.
Close the lid of the lead-lined container securely.
Fully encapsulates the source and prevents accidental exposure or loss of the implant.
5
Report the incident to the appropriate authorities.
Notify the Radiation Safety Officer and the healthcare provider.
Ensures proper medical follow-up for the client and safe, specialized handling of the radioactive material.

Key Concept

Proper emergency response for a dislodged sealed radiation source prioritizes the principles of time, distance, and shielding to minimize radiation exposure before seeking assistance.
Question 288Question →

During a community health workshop on early childhood development, a nurse discusses the predictable sequence of fine motor skill acquisition. Arrange the following milestones in the chronological order in which a child is typically expected to achieve them, from earliest to latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from earliest to latest is: 1) Fading of the primitive palmar grasp reflex, 2) Development of a voluntary palmar grasp, 3) Ability to transfer an object from one hand to the other, 4) Use of a neat pincer grasp, and 5) Ability to successfully stack two blocks.
Fine motor development in infants follows a predictable proximodistal pattern, progressing from gross, uncoordinated movements to refined, specific actions. The primitive grasp reflex must first fade (2-3 months) before voluntary palmar grasping can occur (5 months). As bilateral coordination improves, the infant learns to cross the midline and transfer objects between hands (7 months). Further refinement of the distal digits leads to the neat pincer grasp (10 months). Finally, the ability to precisely release an object allows the child to stack blocks (12-15 months).

Step-by-Step Solution

1
Identify the earliest milestone involving reflexes.
Fading of the primitive palmar grasp reflex is identified as the first event (2-3 months).
Primitive reflexes must disappear before purposeful, voluntary movements can begin.
2
Determine the first purposeful gross grasping milestone.
Development of a voluntary palmar grasp is placed second (5 months).
Infants learn to use their whole hand to intentionally grab objects before they can coordinate individual fingers.
3
Identify the onset of bilateral hand coordination.
The ability to transfer an object from one hand to the other is placed third (7 months).
This milestone bridges simple unilateral grasping and more complex fine motor dexterity.
4
Locate the milestone representing refined finger-thumb coordination.
Use of a neat pincer grasp is placed fourth (10 months).
This represents an advanced stage of proximodistal development, where the child can manipulate small items.
5
Identify the most advanced milestone representing spatial coordination and voluntary release.
The ability to successfully stack two blocks is placed last (12-15 months).
Building a tower requires both precise object placement and intentional release, which are late-stage infancy/early toddlerhood skills.

Question 289Question →

An intubated client in the intensive care unit is awakening from sedation and repeatedly reaches for their endotracheal tube. To ensure client safety and prevent an unplanned extubation, arrange the following nursing interventions in the correct sequence from the least restrictive to the most restrictive.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from least to most restrictive is: providing verbal explanation, assigning a one-to-one sitter, applying unanchored soft mitts, and finally applying anchored wrist restraints.
The standard of care requires nurses to use a stepwise approach, starting with the least restrictive measures. Verbal explanation involves no physical limitation. A sitter provides human supervision without physical devices. Unanchored mitts restrict fine motor grasping but allow arm movement. Anchored wrist restraints severely limit mobility and are the most restrictive.

Step-by-Step Solution

1
Identify the least restrictive, non-physical intervention.
Providing a calm presence and verbally explaining the purpose of the tube.
Verbal de-escalation requires no physical contact or limitation, making it the primary and least restrictive intervention.
2
Determine the next least restrictive alternative that avoids physical devices.
Assigning a trained sitter for continuous one-to-one observation.
A sitter provides human interaction and gentle physical redirection of the hands without tying or binding the client with medical devices.
3
Identify the lowest level of physical restriction.
Applying soft hand mitts that are not tethered to the bed frame.
Unanchored mitts prevent the client from grasping the endotracheal tube but still allow for full range of motion of the arms, preserving more autonomy than tied restraints.
4
Identify the most restrictive measure among the choices.
Securing bilateral soft wrist restraints to the movable portion of the bed frame.
Anchored restraints limit the client's range of motion, tie them to a structure, and are used only as a last resort to prevent life-threatening medical device removal.

Key Concept

When managing a client at risk for disrupting critical life-sustaining therapies, nurses must exhaust all alternative, less restrictive interventions before applying physical restraints, ensuring the client's safety while preserving autonomy as much as possible.
Question 290Question →

A 35-year-old client presents to the women's health clinic for a routine wellness exam. The nurse is coordinating the cervical cancer screening and subsequent follow-up process based on current evidence-based guidelines. Arrange the following nursing actions in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: 1. Instruct the client to abstain from intercourse and creams. 2. Facilitate the collection of the cervical sample. 3. Identify the need for further evaluation based on ASC-US and positive hrHPV results. 4. Prepare the client for a colposcopy. 5. Advise the client about post-procedure discharge from Monsel's solution.
The correct sequence follows the clinical trajectory of health screening from preparation to post-diagnostic care. It begins with pre-screening education (abstaining from intercourse and vaginal creams) to ensure sample viability. This is followed by the screening procedure itself (cytology and hrHPV co-testing). Once the abnormal result (ASC-US with positive hrHPV) is identified, the nurse coordinates the diagnostic workup. This requires pre-procedure education for the colposcopy (explaining acetic acid use). Finally, after the colposcopy and biopsy are complete, the nurse provides post-procedure education regarding expected side effects, such as the characteristic dark discharge caused by the application of Monsel's solution.

Step-by-Step Solution

1
Identify the pre-procedure preparation requirements.
Instructing the client to abstain from intercourse and vaginal creams is placed first.
Accurate health screening requires proper patient preparation before the examination to prevent sample contamination.
2
Identify the primary screening procedure.
Collecting the sample for cytology and hrHPV co-testing is placed second.
This is the core evidence-based health screening intervention for a 35-year-old client.
3
Evaluate the screening results.
Identifying the need for further evaluation based on ASC-US and positive hrHPV is placed third.
Screening results must be analyzed before determining the next appropriate clinical steps in the diagnostic cascade.
4
Prepare the client for the diagnostic workup.
Explaining the colposcopy and acetic acid application is placed fourth.
Pre-procedure education must occur before the diagnostic test is performed to evaluate the abnormal screening.
5
Provide post-procedure instructions.
Advising about the dark discharge from Monsel's solution is placed fifth.
Post-procedure care is the final action after the diagnostic intervention is completed.

Key Concept

Sequencing of cervical cancer screening, interpretation of abnormal results, and coordination of diagnostic follow-up.
Question 291Question →

A 55-year-old client is provided with a multi-card guaiac-based fecal occult blood test (gFOBT) kit during an annual wellness exam for colorectal cancer screening. The nurse provides step-by-step instructions for completing the screening at home. Arrange the following actions in the correct chronological sequence the client must follow.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence for an at-home gFOBT is: dietary preparation, uncontaminated stool collection, first stool smear, second stool smear from a different area, and finally securing and returning the card.
The correct sequence follows the evidence-based progression of patient preparation, specimen collection, specimen application, and handling for a screening gFOBT. Dietary restrictions must be implemented 72 hours before collection. Uncontaminated collection must precede application. The first smear is taken, followed immediately by a second smear from a completely different area of the same stool using the opposite end of the applicator. This maximizes the detection of unevenly distributed blood. Finally, the card is secured and returned within the laboratory's required timeframe.

Step-by-Step Solution

1
Identify the required preparatory phase before stool collection.
The client implements dietary restrictions for 72 hours.
Vitamin C, red meat, and peroxidases in certain raw vegetables can interfere with the guaiac reaction, causing false-negative or false-positive results.
2
Establish the proper method for obtaining the initial specimen.
The stool is collected in a clean, dry environment.
Contamination with urine, toilet water, or cleaning chemicals can compromise the sample.
3
Sequence the first application of the sample.
A thin smear is applied to the first window of the card.
A small sample is required to accurately test for hidden blood.
4
Sequence the secondary application requirement.
A second sample from a different area of the same stool is applied to the second window.
Occult blood from gastrointestinal lesions is often unevenly distributed; sampling two different areas increases detection probability.
5
Determine the final post-collection step.
The test card is closed and returned promptly.
The cards must be processed within a designated timeframe (usually 14 days) to ensure sample viability and accurate screening results.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first wash the puncture site, then notify the charge nurse, report for a medical evaluation, provide a baseline blood sample, and finally initiate post-exposure prophylaxis.
The correct sequence prioritizes immediate physiological safety (first aid), followed by administrative communication to transfer patient care, seeking medical evaluation, obtaining legal and medical baseline testing, and finally initiating pharmacological intervention.

Step-by-Step Solution

1
Wash the puncture site thoroughly with soap and running water.
The wound is cleansed and viral load is minimized.
Local first aid is the absolute highest priority to physically remove infectious material from the broken skin boundary.
2
Notify the charge nurse and the facility's occupational health coordinator.
The incident is officially reported and patient care is handed over.
Informing leadership ensures the nurse is relieved of clinical duties to seek immediate care and triggers the institutional exposure protocol.
3
Report to the employee health department or emergency room for a medical evaluation.
A formal risk assessment is conducted.
A trained provider must evaluate the severity of the exposure and the source patient's specific infectious risk.
4
Provide a personal blood sample for baseline serological testing.
The nurse's pre-exposure HIV, HBV, and HCV status is documented.
Establishing a negative baseline is required before starting medications, to prove any future seroconversion was caused by this specific occupational injury.
5
Initiate the prescribed antiretroviral post-exposure prophylaxis (PEP) regimen.
Prophylactic pharmacological treatment begins.
PEP must be started promptly (ideally within 2 hours) after evaluation and testing to maximally suppress potential viral replication.

Question 293Question →

An employee health nurse is preparing to administer a Mantoux tuberculin skin test (TST) to a newly hired healthcare worker as part of an occupational health screening protocol. In what order should the nurse perform the following actions? Arrange the steps in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of steps for administering a tuberculin skin test is to assess for contraindications, prepare the injection site, administer the intradermal injection, verify wheal formation, and instruct the client on follow-up timing.
The sequence reflects the standard nursing process and evidence-based guidelines for administering an intradermal screening test. First, the nurse must perform a targeted assessment to rule out contraindications, such as a history of a positive Mantoux test, which could lead to a severe localized reaction. Once cleared, the nurse prepares the site on the volar forearm using aseptic technique. The administration of the tuberculin solution follows, utilizing a precise 5- to 15-degree angle with the bevel up to ensure intradermal placement. Immediately following the injection, the nurse evaluates the site for the formation of a 6 to 10 mm wheal, which confirms correct technique. Finally, the nurse provides client education regarding the strict 48- to 72-hour timeframe required for an accurate reading of the screening results.

Step-by-Step Solution

1
Assess the client's history for previous positive reactions or severe reactions to the tuberculin skin test.
The nurse confirms the client is a safe candidate for the screening.
Administering a TST to someone with a prior positive result can cause severe hypersensitivity reactions, including tissue necrosis.
2
Cleanse the volar surface of the forearm with an alcohol swab and allow it to dry completely.
The injection site is properly prepared and sanitized.
Cleansing the skin reduces the risk of introducing surface flora into the dermis during the injection.
3
Insert the needle at a 5- to 15-degree angle with the bevel pointing upward and inject the tuberculin solution.
The purified protein derivative (PPD) is deposited into the intradermal space.
The correct angle and bevel position are necessary to ensure the medication stays within the dermal layer rather than going subcutaneously.
4
Confirm the appearance of a 6 to 10 mm pale wheal at the injection site immediately after administration.
The correct intradermal placement of the screening agent is visually verified.
If no wheal forms, or if it is too small, the injection may have been too deep, invalidating the screening test and requiring a repeat injection.
5
Educate the client to return to the healthcare facility in 48 to 72 hours for the screening interpretation.
The client understands the required timeframe for test evaluation.
A TST must be read by a trained professional within the 48- to 72-hour window; otherwise, the screening is invalid and must be repeated.

Question 294Question →

A pediatric nurse is evaluating the cognitive development of various clients across the lifespan according to Piaget's theory of cognitive development. Arrange the following clinical observations in the chronological order of their expected developmental emergence, from earliest to latest.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence of cognitive development is: 1) Neonatal rooting reflex (early sensorimotor), 2) Searching for a hidden object (object permanence, late sensorimotor), 3) Believing an inanimate pump is angry (animism, preoperational), 4) Understanding volume does not change when transferred (conservation, concrete operational), and 5) Formulating a hypothesis (abstract reasoning, formal operational).
Cognitive development progresses sequentially through Piaget's stages: sensorimotor (innate reflexes, followed by object permanence), preoperational (animism and magical thinking), concrete operational (conservation of volume and mass), and formal operational (abstract hypothesis testing).

Step-by-Step Solution

1
Analyze the observation of a neonate turning their head when their cheek is stroked.
This is the rooting reflex, an innate behavior present from birth during the earliest phase of the sensorimotor stage (0 to 1 month).
Identifying the earliest developmental baseline is necessary to start the sequence.
2
Analyze the observation of an infant searching for a completely covered stethoscope.
This demonstrates object permanence, which develops during the later part of the sensorimotor stage (approximately 8 to 12 months).
Differentiating innate reflexes from learned cognitive concepts within the sensorimotor stage establishes the first two chronological steps.
3
Evaluate the child stating the infusion pump is 'angry' and will bite.
This illustrates animism, a characteristic of the preoperational stage, typically seen in toddlers and preschoolers (ages 2 to 7 years).
Preoperational magical thinking developmentally follows the sensorimotor stage.
4
Assess the school-age client recognizing that transferring liquid does not change its volume.
This indicates mastery of conservation, a hallmark of the concrete operational stage (ages 7 to 11 years).
Concrete logical reasoning regarding physical properties develops after preoperational thought.
5
Examine the adolescent formulating a hypothesis about insulin times and blood glucose.
This reflects hypothetico-deductive reasoning, defining the formal operational stage (ages 11 and older).
Abstract and hypothesis-driven thought is the final stage of Piaget's cognitive development.

Question 295Question →

A glass vacutainer tube containing a client's blood has accidentally dropped and shattered on the floor of the clinical unit. The nurse has retrieved the biological spill kit. Arrange the following actions in the correct sequence to safely manage this hazardous materials spill.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: 1) Don appropriate PPE, 2) Use tongs to retrieve the glass fragments, 3) Deposit the glass into a sharps container, 4) Place absorbent pads over the blood spill, 5) Apply a 1:10 sodium hypochlorite solution to the surface.
When managing a biohazardous spill involving broken glass, the nurse must prioritize personal safety by first donning appropriate personal protective equipment (PPE). The immediate physical hazard (broken glass) must be removed next using mechanical means, such as tongs, to prevent percutaneous injury. These sharps must be immediately secured in a puncture-resistant container. Once the sharps are safely removed, the organic material (blood) should be absorbed with pads or towels to prevent it from inactivating the cleaning agent. Finally, an appropriate chemical disinfectant, such as a 1:10 sodium hypochlorite (bleach) solution, is applied to the surface to destroy any remaining bloodborne pathogens.

Step-by-Step Solution

1
Put on personal protective equipment (PPE).
The nurse is protected from bloodborne pathogens and potential physical injury.
Safety of the healthcare worker is the first priority before handling any hazardous material.
2
Pick up the broken glass with tongs or forceps.
The physical sharps hazard is safely removed from the spill without risking a percutaneous injury.
Glass fragments can puncture standard gloves; mechanical removal prevents direct contact with the sharps.
3
Discard the glass into a sharps container.
The broken glass is securely contained.
Puncture-resistant containers prevent subsequent injuries to environmental services or other staff members.
4
Absorb the remaining blood with paper towels or absorbent pads.
The bulk of the biohazardous fluid is removed from the surface.
Chemical disinfectants are inactivated by large amounts of organic material; the spill must be absorbed before chemical disinfection.
5
Apply a bleach solution (1:10) to the area.
The surface is chemically decontaminated.
Appropriate contact time with a tuberculocidal or bleach solution destroys remaining bloodborne pathogens.

Key Concept

Standard precautions and OSHA guidelines for biological spills involving sharps require immediate mechanical removal of the sharps hazard, followed by absorption of organic material, and concluding with chemical decontamination.

Answer

The correct clinical sequence begins with assessing for reversible physiological causes of agitation, followed by non-contact environmental de-escalation. If agitation persists, the nurse should conceal the medical device. When all alternatives fail, bilateral soft wrist restraints are applied and immediately anchored to the articulating bed frame using quick-release knots. Finally, ongoing care requires sequentially releasing the restraints every two hours for neurovascular assessment.
The established nursing standard of care demands a progressive approach to client agitation, starting with the least restrictive measures. The nurse must first assess for and correct any underlying physiological causes (e.g., hypoxia). If the behavior continues, non-contact interventions (environmental de-escalation) are utilized, followed by contact alternatives (concealing the device with a binder). Only when these measures fail to protect the client's medical treatment are physical restraints applied. Once applied, the immediate priority is safely securing them to the movable bed frame with quick-release knots, followed by initiating the regulatory requirement of releasing them every two hours for comprehensive neurovascular assessments.

Step-by-Step Solution

1
Evaluate for reversible physiological determinants of agitation.
Rules out hypoxia, pain, or a full bladder as the primary physiological catalyst.
Clinical assessment is the mandatory first step of the nursing process prior to implementing any intervention.
2
Institute environmental de-escalation strategies.
Modifies the client's sensory input and environment.
Environmental modification is the least restrictive, non-contact intervention to manage behavioral agitation.
3
Conceal the PEG tube beneath an abdominal binder.
Blocks visual and tactile access to the medical device.
This acts as a targeted physical barrier and is a less restrictive alternative to restraining the client's upper extremities.
4
Apply bilateral soft wrist restraints.
Prevents the client's hands from grasping the abdomen.
Physical restraints are utilized strictly as a last resort when less restrictive measures fail to protect life-sustaining medical treatments.
5
Anchor restraint straps to the articulating bed frame with quick-release knots.
Secures the physical restraints safely.
Tying to the movable frame prevents traction injuries when the bed's position is adjusted, and quick-release ties ensure rapid removal during emergencies.
6
Release restraints sequentially every two hours for neurovascular assessment.
Maintains skin integrity and peripheral tissue perfusion.
This is the mandated regulatory standard of care for clients placed in non-violent medical-surgical restraints.

A client arrives at a community clinic triage desk exhibiting a high fever, cough, coryza, and a diffuse maculopapular rash. The triage nurse suspects rubeola (measles). Arrange the following nursing interventions in the correct chronological sequence to effectively implement transmission-based precautions.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first apply a surgical mask to the client for source control, escort them to an airborne infection isolation room, secure the door to establish negative pressure, don an N95 respirator for self-protection, and finally proceed with the clinical assessment.
For highly contagious airborne pathogens like rubeola (measles), immediate containment is the primary goal. Source control (masking the client) is the fastest, most effective first action. Moving the client to a negative-pressure room and sealing the door establishes environmental control. Finally, ensuring the nurse is protected with an N95 respirator allows for safe, sustained close contact during the physical assessment.

Step-by-Step Solution

1
Initiate source control
The client wears a surgical mask over their nose and mouth.
Placing a mask on the infectious client immediately stops the wide dispersion of airborne viral particles into the public waiting area.
2
Relocate to an appropriate isolation environment
The client is moved from the triage desk to an AIIR.
Airborne pathogens require negative-pressure ventilation systems to safely exhaust contaminated air outside the facility.
3
Secure the isolation environment
The AIIR door is completely closed.
Negative pressure cannot be maintained if the door is open, which would allow infectious air to circulate into adjoining corridors.
4
Apply staff personal protective equipment
The nurse dons an N95 respirator.
Healthcare personnel must have high-level filtration protection (N95 or PAPR) before inhaling the ambient air inside an airborne isolation room.
5
Conduct nursing care
The comprehensive clinical assessment is performed.
Safe patient care can only be provided once transmission risks to the public, facility, and healthcare worker are neutralized.

An older adult client with acute delirium is continuously pulling at a newly inserted peripheral intravenous (IV) catheter. The primary healthcare provider has been notified. Arrange the following safety interventions in order from the least restrictive measure to the most restrictive measure.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from least restrictive to most restrictive is: attempting verbal de-escalation, concealing the IV site, applying unanchored padded hand mitts, and finally securing soft wrist restraints to the bed frame.
The standard of care for client safety requires implementing interventions starting with the least restrictive measures. Verbal interventions come first, followed by environmental modifications like concealing the site. If those fail, mild physical barriers like unanchored mitts are used. Tethered physical restraints are utilized only when all other alternatives have failed.

Step-by-Step Solution

1
Identify the least restrictive independent nursing intervention.
Attempting verbal de-escalation is the initial step as it imposes no physical restriction on the client.
Nursing standards dictate starting with non-physical, interpersonal communication techniques before altering the environment or applying physical barriers.
2
Identify the next least restrictive environmental modification.
Concealing the IV site with a long-sleeved gown removes the visual trigger.
Out of sight, out of mind principles work well for confused clients and do not restrict their movement.
3
Evaluate physical barriers that do not tether the client.
Applying unanchored padded hand mitts prevents the client from grasping the IV line while preserving arm mobility.
Mitts are a physical barrier but are less restrictive than tying a limb to a fixed structure.
4
Identify the most restrictive intervention.
Applying soft wrist restraints tied to the bed frame is the final resort.
This severely limits physical mobility and requires strict adherence to legal guidelines, provider prescriptions, and facility restraint protocols.

A young adult client is brought to the emergency department unresponsive, with pinpoint pupils and a respiratory rate of 6 breaths per minute. The nurse suspects an acute opioid overdose resulting from high-risk substance use. Arrange the following nursing actions in the correct order of priority from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first secure the airway and ventilate, then administer the opioid antagonist, follow up with continuous monitoring for re-sedation, and finally provide harm-reduction education once the client is completely stable.
In emergency situations involving high-risk substance use, such as an opioid overdose, nursing care must be prioritized using the ABC framework (Airway, Breathing, Circulation). Airway and breathing are the immediate priority when the respiratory rate is critically low. Pharmacological intervention follows to reverse the cause. Monitoring is then essential because the reversal agent often wears off faster than the ingested opioid. Finally, health promotion and harm-reduction education are provided at the end of the sequence when the client is fully stable and ready for discharge.

Step-by-Step Solution

1
Prioritize physiological needs using the ABC framework.
Airway patency and supportive ventilation are identified as the first intervention.
Without an open airway and adequate breathing, all other interventions will fail to prevent hypoxic brain injury or death.
2
Address the underlying pharmacological cause of the emergency.
Administration of the opioid antagonist is identified as the second intervention.
Reversing the opioid toxicity restores the client's spontaneous respiratory drive.
3
Evaluate the client's response to the pharmacological intervention over time.
Continuous monitoring for re-sedation is identified as the third intervention.
Naloxone has a short half-life, meaning the client can slip back into respiratory depression if the opioid outlasts the reversal agent.
4
Incorporate health promotion and prevention strategies.
Harm-reduction education is identified as the final intervention.
Psychosocial interventions and education require a conscious, cognitively intact, and physiologically stable client.

A nurse is preparing to enter the room of a client placed on contact and droplet precautions. Arrange the steps for donning (putting on) personal protective equipment (PPE) in the correct sequence 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 first perform hand hygiene, then put on the isolation gown, followed by the surgical mask, then the face shield, and finally put on clean gloves.
According to standard infection control guidelines from organizations like the CDC, the correct sequence for donning PPE ensures maximum protection and prevents self-contamination. The process begins with hand hygiene. Next, the gown is donned to cover the torso and clothing. Then, the mask is secured to protect the respiratory tract, followed by the face shield for eye protection. Finally, gloves are put on last, pulled securely over the cuffs of the gown to prevent any skin exposure.

Step-by-Step Solution

1
Perform hand hygiene.
Hands are clean and ready to handle protective equipment safely.
Reduces the risk of transferring pathogens to the clean PPE prior to wearing it.
2
Put on the isolation gown.
The nurse's torso, arms, and clothing are covered.
Provides a large foundational barrier against infectious materials in the client's environment.
3
Put on the surgical mask.
The nose and mouth are protected.
Prevents the inhalation of droplet-transmitted pathogens.
4
Put on the face shield.
The eyes and upper face are shielded.
Acts as a critical barrier against potential splashes, sprays, or large infectious droplets.
5
Put on clean gloves.
Hands and wrists are completely covered and sealed.
Putting gloves on last allows the nurse to stretch the gloves over the gown cuffs, maintaining a continuous barrier.
