Question 3281Question →

A nurse is preparing to withdraw a prescribed intravenous medication from a glass ampule. Place the steps for this procedure in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is: tap the ampule to clear the neck, wrap the neck with a protective barrier, snap the neck away from the body, withdraw the medication using a filter needle, and finally replace the filter needle with an appropriate administration device.
Safe medication preparation from an ampule requires a strict procedural sequence to prevent injury and contamination. The medication must first be tapped down into the base to prevent dosage loss. The nurse must then protect their hands with a barrier before snapping the neck away from the body to prevent cuts. Finally, a filter needle is strictly required to prevent microscopic glass shards from being drawn into the syringe, and this filter needle must be replaced before the medication can be safely administered to the client.

Step-by-Step Solution

1
Ensure all medication is in the bottom of the ampule by tapping the top.
Medication is cleared from the top chamber.
Prevents spilling and losing a portion of the prescribed dose when the top is snapped off.
2
Wrap the neck of the ampule with a gauze pad and snap it away from the body.
The ampule is opened safely.
Protects the nurse's hands from cuts and ensures flying glass fragments are directed away.
3
Withdraw the medication using a filter needle attached to the syringe.
Medication is drawn into the syringe.
The filter prevents any microscopic glass shards created during the breaking process from entering the syringe.
4
Change the needle before administration.
The syringe is safely prepared for client injection.
A filter needle is intended only for withdrawing from glass ampules and must be replaced to prevent tissue injury or injecting trapped glass.

Question 3282Question →

A client diagnosed with a massive pulmonary embolism is receiving a continuous intravenous (IV) infusion of unfractionated heparin. The healthcare provider prescribes an intermittent IV antibiotic to be infused over 90 minutes. Upon checking the facility's drug reference guide, the nurse notes that the antibiotic is chemically incompatible with heparin. The client currently has only one patent 20-gauge peripheral IV catheter. Which action is most appropriate for the nurse to take?

Show answer & explanation

Answer: Establish a second peripheral IV access to administer the intermittent antibiotic infusion.

Answer

The most appropriate action is to establish a second peripheral IV access to administer the intermittent antibiotic infusion.
The client requires a continuous infusion of heparin for a massive pulmonary embolism. Heparin has a short half-life, and pausing the infusion for 90 minutes to administer an incompatible antibiotic will cause subtherapeutic activated partial thromboplastin time (aPTT) levels, risking life-threatening thrombus extension. Establishing a second peripheral IV access is the only safe action that allows both the critical continuous infusion and the necessary antibiotic to be administered concurrently without chemical precipitation or therapeutic interruption.

Step-by-Step Solution

1
Analyze the client's current therapies.
The client is on a continuous heparin infusion for a critical condition (pulmonary embolism) and requires a 90-minute intermittent antibiotic.
To understand the clinical priority and pharmacokinetics of the prescribed treatments.
2
Evaluate the compatibility of the prescribed medications.
The antibiotic and heparin are chemically incompatible.
To determine if they can be safely co-administered in the same IV line.
3
Determine the physiological impact of pausing the continuous infusion.
Pausing heparin for 90 minutes is unsafe due to its short half-life and the high risk of clot extension.
To rule out the standard 'flush, infuse, flush' technique, which is only safe for short 2-5 minute IV pushes.
4
Identify the safest alternative administration method.
Starting a second peripheral IV line allows both necessary therapies to run simultaneously without physical interaction.
To maintain therapeutic anticoagulant levels while properly treating the infection.

Question 3283Question →

A critically ill adult client in the intensive care unit has a triple-lumen central venous catheter. The client is receiving continuous intravenous infusions of total parenteral nutrition (TPN) via the distal lumen, propofol via the medial lumen, and norepinephrine via the proximal lumen. The client's mean arterial pressure acutely drops to 45 mm Hg45\text{ mm Hg}. The healthcare provider prescribes a stat 500 mL500\text{ mL} bolus of 0.9%0.9\% sodium chloride and the initiation of a continuous vasopressin infusion. Which of the following is the most appropriate nursing action?

Show answer & explanation

Answer: Y-site the vasopressin infusion into the proximal lumen with the norepinephrine, and establish a new peripheral intravenous catheter for the sodium chloride bolus.

Answer

The most appropriate action is to Y-site the vasopressin infusion into the proximal lumen with the norepinephrine, and establish a new peripheral intravenous catheter for the sodium chloride bolus.
The correct action is to establish a new peripheral IV for the fluid bolus and Y-site the vasopressin with the norepinephrine. Vasopressin and norepinephrine are compatible and commonly infused together. A rapid fluid bolus must never be administered through a lumen that is infusing continuous vasoactive or sedative medications (such as norepinephrine or propofol) because the bolus will rapidly flush the medication remaining in the catheter's dead space into the client, potentially causing a fatal overdose. Additionally, the TPN line must remain dedicated.

Step-by-Step Solution

1
Evaluate the safety of using the proximal lumen (norepinephrine) for a fluid bolus.
Ruled out because flushing a vasoactive line will deliver a dangerous bolus of the pressor.
Norepinephrine is highly concentrated; rapid flushing of the dead space can cause a severe hypertensive crisis.
2
Evaluate the safety of using the medial lumen (propofol) for a fluid bolus.
Ruled out because flushing a sedative line will deliver a dangerous bolus of the sedative.
Propofol causes respiratory depression and hypotension; rapid flushing can lead to apnea and cardiovascular collapse.
3
Evaluate the safety of using the distal lumen (TPN) for a fluid bolus.
Ruled out because TPN lines must remain dedicated.
Using the TPN line increases infection risk, introduces incompatibilities, and pausing TPN abruptly can cause severe rebound hypoglycemia.
4
Determine the appropriate access for the vasopressin and the sodium chloride bolus.
Y-site vasopressin with norepinephrine, and place a new peripheral IV for the fluid bolus.
Vasopressin and norepinephrine are compatible. A new peripheral line is required to safely administer a rapid fluid bolus without flushing active medications from dead space.

Key Concept

Safe administration of parenteral fluids and vasoactive medications via central venous catheters, specifically avoiding the rapid flushing of dead space containing continuous critical infusions.

Question 3284Question →

During bedside rounds, a rapid response team nurse evaluates a client with sepsis-induced encephalopathy. The client is severely agitated and continuously pulling at their central venous catheter and indwelling urinary catheter. Place the following safety interventions in the correct sequence of escalation, starting from the first priority action to the measure of last resort.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence of escalating safety interventions begins with assessing for physiological causes, followed by implementing basic environmental modifications, concealing the medical devices, assigning a continuous bedside observer, and finally, obtaining a prescription for physical restraints as a last resort.
The standard of care for managing an agitated client who is at risk of dislodging medical devices mandates a stepwise escalation from the least restrictive to the most restrictive interventions. The process begins with assessing and treating underlying physiological causes. If agitation persists, the nurse implements environmental modifications and attempts to remove visual triggers by concealing the devices. If these measures fail, a continuous bedside sitter is employed to redirect the client. Finally, if all less restrictive alternatives have been exhausted and the client remains at risk of self-harm, the nurse must obtain a provider's prescription to apply physical restraints.

Step-by-Step Solution

1
Determine the priority action according to the nursing process.
Assessment is the initial step.
Nurses must first identify and treat any reversible physiological causes of the client's agitation, such as hypoxia or pain.
2
Identify the least restrictive non-pharmacological intervention.
Environmental modifications are prioritized next.
Creating a calm environment with minimal sensory overload is a foundational, non-restrictive safety measure.
3
Select the next least restrictive alternative for a client pulling at tubes.
Device concealment is the next logical step.
Hiding lines and catheters under clothing or stockinettes removes the visual stimulus without restricting the client's movement.
4
Determine the appropriate intervention when environmental and visual modifications fail.
Assigning a one-to-one bedside observer is required.
Direct continuous supervision maintains client safety and redirects behavior without the need for physical restraints.
5
Identify the measure of last resort.
Obtaining a provider prescription for physical restraints is the final step.
Restraints are legally and ethically the most restrictive option and are only permissible when all less restrictive alternatives have been exhausted.

Question 3285Question →

An intensive care nurse is managing an intubated client who is severely agitated and attempting to remove the endotracheal tube. After less restrictive measures have failed, the nurse initiates the application of bilateral soft wrist restraints. Arrange the following nursing actions in the correct chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: obtaining staff assistance, applying the restraints to the movable bed frame, assessing neurovascular status, contacting the healthcare provider for a prescription, and documenting the event.
In a behavioral emergency where a client poses an immediate risk to themselves (such as pulling out an endotracheal tube), the nurse's first priority is securing the client safely with the help of other staff. Once help is present, the restraints are applied correctly to the movable portion of the bed frame to prevent injury during bed adjustments. Immediately following application, the nurse must perform a neurovascular assessment to ensure circulation is not compromised. After the client is physically safe and stable, the nurse contacts the healthcare provider to obtain the required prescription, and finally documents the entire event.

Step-by-Step Solution

1
Call for assistance from other healthcare personnel.
Adequate staff is present to safely manage the client.
Attempting to restrain an agitated client alone can result in injury to both the nurse and the client.
2
Secure the restraint straps to the movable part of the bed frame.
Restraints are applied safely without risking tension during bed movement.
Tying restraints to the movable frame ensures they will not tighten or pull inappropriately if the bed's position is changed.
3
Evaluate peripheral pulses, capillary refill, and skin temperature.
Neurovascular status is confirmed as intact.
Immediate assessment ensures the applied restraints are not compromising distal blood flow or causing nerve damage.
4
Contact the primary healthcare provider to obtain the restraint prescription.
Legal and facility protocols for emergency restraint use are initiated.
In a behavioral emergency, restraints can be applied for immediate safety, but the provider must be notified promptly (usually within 1 hour) to evaluate the client and provide an order.
5
Document the interventions, client behaviors, and neurovascular assessments in the medical record.
The emergency event is properly recorded.
Accurate and timely documentation provides a legal record of the emergency, the alternative interventions attempted, and the client's condition.

Question 3286Question →

A nurse is developing a plan of care for a 72-year-old client who recently suffered an ischemic stroke and is now receiving continuous enteral nutrition via a nasogastric (NG) tube. Which of the following actions should the nurse include to minimize the risk of complications? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Elevate the head of the bed to at least 30 degrees while the feeding is infusing.; Verify tube placement by checking the pH of aspirated gastric contents.; Flush the feeding tube with 30 mL of water before and after medication administration.

Answer

The correct actions to minimize complications are elevating the head of the bed, verifying tube placement with pH testing, and flushing the tube with water before and after medications.
The correct actions focus on mitigating the primary risks of enteral feeding. Elevating the head of the bed to at least 30 degrees uses gravity to prevent gastric reflux and aspiration. Verifying tube placement by checking the pH of aspirated contents ensures the formula is delivered to the stomach, not the lungs. Flushing the tube with 30 mL of water before and after medications prevents chemical interactions that could occlude the tubing.

Step-by-Step Solution

1
Identify the primary physiological risks associated with continuous enteral feedings via a nasogastric (NG) tube.
The most significant immediate risks include pulmonary aspiration, tube occlusion, and improper tube displacement.
Understanding potential complications is essential for selecting appropriate preventive interventions.
2
Evaluate each nursing intervention against established safety protocols for enteral feedings.
Elevating the head of the bed prevents aspiration. Checking pH confirms placement. Flushing maintains patency. Conversely, pausing the feeding is required when laying the client flat. Lung assessments cannot be delegated. Abdominal assessment requires auscultation prior to palpation.
Applying standard nursing guidelines ensures safe practice and objective risk reduction.
3
Select all the appropriate evidence-based interventions.
The correct safety interventions are elevating the head of the bed, confirming placement via pH, and routinely flushing the tube.
These specific actions directly address and mitigate the identified risks of enteral feeding.

Key Concept

To reduce the risk of complications during enteral tube feedings, the nurse must implement aspiration precautions, maintain tube patency, confirm proper placement, and perform accurate, non-delegated assessments.

Question 3287Question →

A nurse is preparing to administer a prescribed intravenous (IV) push medication through a client's continuous IV infusion line. Which action is essential for the nurse to perform prior to injecting the medication?

Show answer & explanation

Answer: Verify the compatibility of the medication with the primary IV fluid.

Answer

The nurse must verify the compatibility of the medication with the primary IV fluid.
Before administering any IV push medication into an existing continuous infusion, checking the compatibility of the drug with the running fluid is the absolute priority. If the substances are incompatible, they can form precipitates that may cause a fatal embolus. When fluids are incompatible, the nurse must use a different IV site or properly flush the primary line with normal saline both before and after the medication push.

Step-by-Step Solution

1
Identify the route and method of medication administration.
The medication is to be given via IV push through an active, continuous IV infusion line.
Understanding the route determines the specific safety checks required before administration.
2
Recognize the potential risks of mixing intravenous substances.
Combining an IV push medication with an incompatible continuous IV fluid can cause crystallization or precipitation in the tubing.
Precipitates can enter the client's bloodstream and act as emboli, causing severe tissue damage or life-threatening complications.
3
Determine the highest priority safety action.
The nurse must consult a drug reference guide to verify that the medication and the running IV fluid are physically and chemically compatible.
Checking compatibility is a foundational standard of care that prevents adverse drug-fluid reactions and ensures safe intravenous therapy.

Question 3288Question →

A client experiencing an acute exacerbation of chronic obstructive pulmonary disease (COPD) becomes increasingly lethargic. Recent arterial blood gas (ABG) analysis reveals a pH of 7.25, PaCO2 of 72 mm Hg, HCO3 of 28 mEq/L, and PaO2 of 58 mm Hg. To reduce the risk of impending respiratory failure, which intervention should the nurse implement first?

Show answer & explanation

Answer: Prepare the equipment for noninvasive positive pressure ventilation or intubation.

Answer

The correct action is to prepare the equipment for noninvasive positive pressure ventilation or intubation.
The client is exhibiting clear signs of acute respiratory failure and CO2 narcosis (lethargy paired with severe respiratory acidosis: pH 7.25 and PaCO2 72 mm Hg). The absolute priority action to reduce the risk of respiratory arrest and death is to assist with ventilation. This actively blows off excess carbon dioxide and improves oxygenation, which is achieved through noninvasive positive pressure ventilation (such as BiPAP) or mechanical intubation.

Step-by-Step Solution

1
Analyze the client's ABG results and neurological status.
The nurse identifies acute respiratory acidosis (pH 7.25, high PaCO2) and CO2 narcosis evidenced by the increasing lethargy.
Recognizing the physiological signs of impending respiratory arrest is the first step in risk reduction.
2
Apply the ABCs (Airway, Breathing, Circulation) framework for prioritization.
The nurse determines that immediate intervention to support breathing and ventilation takes precedence over further assessment or circulation optimization.
Airway and breathing must be secured immediately to prevent cardiopulmonary collapse.
3
Select the intervention that directly addresses the inadequate ventilation.
The nurse prepares for mechanical or positive pressure ventilation.
Ventilatory support is necessary to blow off the excess carbon dioxide and restore a safe blood pH and oxygenation level.

Key Concept

Identifying early indicators of respiratory failure and prioritizing airway and breathing interventions over secondary assessments.
Question 3289Question →

During the overnight shift in the neurosurgical intensive care unit, the nurse assumes care of a client who underwent a supratentorial tumor resection earlier in the day. Upon the hourly evaluation, the client demonstrates lethargy but withdraws purposefully from noxious stimuli. The physiological monitor displays a blood pressure of 172/64172/64 mmHg, an apical pulse of 5252 beats per minute, and an irregular respiratory pattern of 1010 breaths per minute. The indwelling catheter drainage system has collected 550550 mL of pale urine over the last 6060 minutes with a specific gravity of 1.0031.003. An arterial blood gas panel drawn on 40%40\% supplemental O2O_2 reveals a pHpH of 7.287.28, PaCO2PaCO_2 of 5454 mmHg, HCO3−HCO_3^- of 2424 mEq/L, and PaO2PaO_2 of 8888 mmHg. Based on this diagnostic data, which action must the nurse prioritize to prevent lethal decompensation?

Show answer & explanation

Answer: Maintain the cervical spine in a strict neutral axis without flexion and immediately collaborate with the critical care team to establish invasive ventilatory support.

Answer

Maintain the cervical spine in a strict neutral axis without flexion and immediately collaborate with the critical care team to establish invasive ventilatory support.
The correct action directly addresses the most critical threat to the client's survival. The presentation of a widened pulse pressure, profound bradycardia, and altered respirations is Cushing's triad, indicating an extreme elevation in intracranial pressure. Compounding this, the client is in acute respiratory acidosis with hypercapnia (PaCO2PaCO_2 of 5454 mmHg). Because carbon dioxide is a potent cerebral vasodilator, this hypercapnia dramatically increases cerebral blood volume, pushing the ICP even higher. Establishing invasive ventilation is required to lower the PaCO2PaCO_2 and induce mild cerebral vasoconstriction, while maintaining a neutral neck axis ensures unobstructed jugular venous return.

Step-by-Step Solution

1
Analyze the vital signs and neurological assessment to identify the primary physiological threat.
The combination of hypertension with a widened pulse pressure (172/64172/64 mmHg), bradycardia (5252 bpm), and irregular respirations is identified as Cushing's triad.
Recognizing Cushing's triad is essential as it is a late, life-threatening indicator of severely increased intracranial pressure (ICP) and impending brainstem herniation.
2
Interpret the arterial blood gas (ABG) values in the context of the neurological status.
The ABG reveals uncompensated respiratory acidosis (pHpH 7.287.28, PaCO2PaCO_2 5454 mmHg) due to hypoventilation.
Elevated arterial carbon dioxide (PaCO2PaCO_2) is a potent cerebral vasodilator. In a client with a rigid cranial vault and already elevated ICP, vasodilation causes a catastrophic secondary increase in pressure.
3
Evaluate the secondary findings (high urine output and low specific gravity) and prioritize interventions based on the most immediate threat to life.
While the 550550 mL urine output indicates postoperative diabetes insipidus, the respiratory failure driving the intracranial hypertension is the most acute threat.
Airway and breathing management must take precedence to reverse hypercapnia-induced cerebral vasodilation before addressing the fluid imbalance.
4
Determine the safest and most effective nursing interventions to mitigate the elevated ICP.
The nurse must ensure a neutral cervical alignment to facilitate venous drainage and prepare for mechanical ventilation to lower the PaCO2PaCO_2.
Proper positioning and immediate respiratory support directly reduce the physiological mechanisms exacerbating the intracranial pressure, thus reducing the risk of lethal herniation.

Key Concept

Synthesizing neurological assessment (Cushing's triad) with ABG interpretation to prioritize risk reduction for impending brain herniation.

Question 3290Question →

A nurse is caring for a client with an acute exacerbation of chronic obstructive pulmonary disease (COPD) who is experiencing severe hypoxia-induced restlessness. The client is persistently attempting to remove their continuous positive airway pressure (CPAP) mask and peripheral intravenous (IV) catheter. Arrange the following nursing actions in the correct sequence for managing this client's behavior, progressing from the initial nursing process step to the most restrictive intervention. All options must be used.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with assessment, followed by verbal reorientation, camouflaging the lines, assigning a sitter, and finally applying physical restraints.
The safe use of restraints requires nurses to follow the principle of the least restrictive alternative. This means interventions must escalate sequentially. First, the nurse must assess for and treat underlying physiological causes of agitation, such as hypoxia. Next, the nurse should employ the least restrictive behavioral intervention, which is verbal reorientation. If unsuccessful, the nurse implements environmental modifications, such as camouflaging the medical devices to remove visual triggers. If the client continues to pull at lines, instituting continuous one-to-one observation (a sitter) provides safety without physical restriction. Finally, if all less restrictive measures fail and are documented as ineffective, the nurse may apply physical restraints as a last resort, provided there is a valid primary healthcare provider's prescription.

Step-by-Step Solution

1
Assess respiratory status and oxygen saturation.
Identifies whether the agitation is secondary to worsening hypoxia.
The nursing process always begins with assessment to rule out and treat life-threatening physiological causes before addressing behaviors.
2
Attempt verbal reorientation and explain the medical necessity of the equipment.
Provides cognitive support and may de-escalate the client's behavior.
Verbal intervention is the least restrictive behavioral approach.
3
Conceal the intravenous site and continuous positive airway pressure (CPAP) tubing.
Removes the visual trigger that prompts the client to pull at the devices.
Camouflage is a non-restrictive environmental modification that often effectively distracts the client.
4
Assign unlicensed assistive personnel for continuous one-to-one observation.
Ensures immediate bedside intervention if the client attempts to remove life-sustaining equipment.
Direct observation ensures safety without the use of physical force or restriction.
5
Apply prescribed bilateral soft wrist restraints.
Physically prevents the client from removing the CPAP mask and IV catheter.
Physical restraints are the most restrictive measure and are legally permitted only as a last resort when all other alternatives have failed.

Question 3291Question →

A client is scheduled to receive a bolus enteral formula via an established nasogastric (NG) tube. Which sequence of actions must the nurse execute to safely deliver this nutritional support? Arrange the clinical steps in the correct chronological order from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The safe sequence is to first position the client upright, verify tube placement and residual volume, perform a pre-flush with water, administer the nutritional formula, and finally execute a post-flush while maintaining the upright position.
Safe enteral feeding requires a rigorous, systematic approach to prevent life-threatening pulmonary aspiration and mechanical tube complications. Elevating the head of the bed uses gravity to protect the airway and must be done first. Verifying placement and residual volume ensures the stomach can accommodate the feed safely without reflux. The pre-flush verifies tube patency, the feeding provides necessary nutrition, and the post-flush maintains tube hygiene while continued elevation protects against post-feeding aspiration.

Step-by-Step Solution

1
Elevate the head of the client's bed to a minimum of 30 degrees.
The client is placed in an upright position.
Gravity is the primary defense against aspiration. The airway must be protected before any manipulation of the gastric tube begins.
2
Aspirate the stomach contents to assess residual volume and confirm tube placement.
Tube placement is verified and gastric emptying is assessed.
Ensuring the tube hasn't migrated to the lungs and that the stomach isn't overly full prevents pulmonary aspiration of stomach contents.
3
Instill 30 mL of sterile water to flush the nasogastric tube.
The tube is cleared and patency is confirmed.
Flushing verifies that the tube is not kinked or clogged, preparing it for the thicker formula.
4
Administer the prescribed amount of the enteral nutritional formula.
The client receives the prescribed nutrition.
With safety checks complete, the bolus feeding can be infused securely.
5
Flush the tube with an additional 30 mL of water and maintain the elevated bed position.
The tube is cleared of formula and the client remains positioned safely.
The final flush prevents the formula from coagulating and occluding the tube, while continued elevation prevents post-feeding reflux and aspiration.

Question 3292Question →

A nurse is evaluating a newborn to determine the 5-minute APGAR score. The newborn's assessment findings are as follows:

- Heart rate: 112 beats/min
- Respiratory effort: Slow, weak cry
- Muscle tone: Some flexion of extremities
- Reflex irritability: Grimace in response to stimulation
- Color: Body pink, hands and feet cyanotic

Calculate the newborn's APGAR score.

Show answer & explanation

Answer: 6

Answer

6
The APGAR score is calculated based on five parameters, each scored from 0 to 2. This newborn receives 1 point for Appearance (acrocyanosis), 2 points for Pulse (>100 bpm), 1 point for Grimace (grimace to stimulation), 1 point for Activity (some flexion), and 1 point for Respiration (weak cry). The total sum is 1 + 2 + 1 + 1 + 1 = 6 points.

Step-by-Step Solution

1
Assign points for Appearance (Color)
1 point
The newborn has a pink body but cyanotic extremities (acrocyanosis), which warrants 1 point instead of 2 (completely pink) or 0 (completely blue/pale).
2
Assign points for Pulse (Heart rate)
2 points
A heart rate of 112 beats/min is above the 100 beats/min threshold, earning the maximum of 2 points.
3
Assign points for Grimace (Reflex irritability)
1 point
A grimace response to stimulation scores 1 point, whereas a vigorous cry or active withdrawal would score 2 points.
4
Assign points for Activity (Muscle tone)
1 point
Demonstrating only some flexion of the extremities earns 1 point, as opposed to active motion which would earn 2 points.
5
Assign points for Respiration (Respiratory effort)
1 point
A slow, weak cry scores 1 point, unlike a good, strong cry which would score 2 points.
6
Calculate the total score
6 points
1 (Color) + 2 (Pulse) + 1 (Grimace) + 1 (Activity) + 1 (Respiration) = 6.

A nurse is caring for a client in the intensive care unit who is experiencing a hypertensive emergency. The client weighs 209 lbs209\text{ lbs}. The healthcare provider prescribes a continuous intravenous infusion of sodium nitroprusside at 3 mcg/kg/min3\text{ mcg/kg/min}. The pharmacy dispenses a premixed IV bag containing 50 mg50\text{ mg} of sodium nitroprusside in 250 mL250\text{ mL} of 5%5\% dextrose in water (D5W).

At what rate, in mL/hr\text{mL/hr}, should the nurse set the infusion pump? (Record your answer using one decimal place.)

Show answer & explanation

Answer: 85.5

Answer

85.5
To safely administer a weight-based continuous IV infusion ordered in mcg/kg/min, the nurse must execute several sequential conversions. First, convert the weight to kg (209 lbs / 2.2 = 95 kg). Next, find the hourly dose by multiplying the weight by the order and then by 60 minutes (95 kg * 3 mcg/kg/min * 60 min/hr = 17,100 mcg/hr). Then, determine the concentration of the IV bag by converting mg to mcg (50 mg = 50,000 mcg) and dividing by the volume (50,000 mcg / 250 mL = 200 mcg/mL). Finally, divide the required hourly dose by the concentration to find the correct pump rate (17,100 mcg/hr / 200 mcg/mL = 85.5 mL/hr).

Step-by-Step Solution

1
Convert the client's weight to kilograms.
95 kg
The medication is dosed based on weight in kg, but the client's weight is provided in lbs.
2
Calculate the patient-specific dose per minute.
285 mcg/min
Multiply the prescribed dose (3 mcg/kg/min) by the client's weight in kg to find the total per-minute dose.
3
Calculate the dose per hour.
17,100 mcg/hr
Infusion pumps are programmed in mL/hr, so the dose must reflect an hourly rate rather than a minute rate.
4
Convert the medication weight in the bag from mg to mcg.
50,000 mcg
The prescribed dose is calculated in mcg, but the IV bag contains mg. Units must match to calculate concentration.
5
Calculate the IV bag concentration.
200 mcg/mL
Divide the total micrograms (50,000) by the total volume (250 mL) to determine how many micrograms are in each mL.
6
Calculate the infusion pump rate in mL/hr.
85.5 mL/hr
Divide the required hourly dose (17,100 mcg/hr) by the concentration (200 mcg/mL) to find the volume needed per hour.

An adolescent client admitted to an acute behavioral health facility begins throwing furniture and physically threatening peers. After verbal de-escalation and pharmacological interventions fail to calm the client, four-point mechanical restraints are applied to prevent immediate severe injury. Which action must the registered nurse implement next?

Show answer & explanation

Answer: Initiate continuous, in-person observation of the client for the duration of the restraint use.

Answer

Initiate continuous, in-person observation of the client for the duration of the restraint use.
When mechanical restraints are applied for violent or self-destructive behavior, strict safety standards require continuous, in-person observation of the client. This one-to-one monitoring is critical to immediately detect respiratory compromise, impaired circulation, or changes in psychological status, ensuring the restraints can be removed at the earliest possible safe moment.

Step-by-Step Solution

1
Identify the type of restraint indication described in the clinical scenario.
The client is exhibiting violent, self-destructive behavior that poses an immediate physical threat.
Different restraint indications (medical-surgical vs. violent/behavioral) have distinct regulatory requirements for monitoring and order renewal.
2
Determine the safety and monitoring requirements specific to violent behavioral restraints.
Standards require continuous, face-to-face observation by a trained staff member.
Continuous monitoring ensures the client's airway and circulation are not compromised and allows for rapid removal once the client is no longer an imminent threat.
3
Evaluate the remaining options against legal and safety standards for restraints and delegation.
Using square knots on side-rails, obtaining PRN orders, and delegating clinical assessments to unlicensed assistive personnel (UAP) are all severe safety violations.
Eliminating unsafe practices isolates the correct evidence-based nursing action.

This is a correct action.
Checking for clarity, precipitates, and expiration dates prevents the administration of contaminated or degraded parenteral solutions.

Key Concept

Safe administration of parenteral therapies requires strict adherence to compatibility guidelines, accurate mathematical dosing based on current data, and continuous evaluation of equipment and fluid integrity.
Question 3296Question →

A catastrophic explosion has occurred at a multi-story indoor shopping complex, resulting in a mass casualty incident. A triage nurse is systematically evaluating victims at the scene using the Simple Triage and Rapid Treatment (START) algorithm. Which victim should the nurse classify as requiring an Immediate (Red) triage tag?

Show answer & explanation

Answer: A victim with a crushed lower extremity who is breathing 24 breaths per minute, correctly answers orientation questions, but has an absent radial pulse.

Answer

The victim with a crushed lower extremity who has an absent radial pulse, despite exhibiting normal respirations and an intact mental status.
The correct answer identifies a victim who fails the perfusion parameter of the START algorithm. Although this victim's respirations (24/min) and mental status (oriented) are acceptable, the absent radial pulse is a definitive indicator of profound hypovolemic shock. In the stepwise START assessment, failing any single critical parameter (respirations >30, absent radial pulse, or unable to follow commands) immediately designates the client as an Immediate (Red) priority.

Step-by-Step Solution

1
Assess the victim's ability to walk.
Ambulatory victims are tagged Green (Minor). Non-ambulatory victims require further assessment.
Walking inherently indicates an adequate airway, breathing, and circulation.
2
Evaluate spontaneous respirations in non-ambulatory victims.
Victims who are apneic after airway repositioning are tagged Black. Those with a respiratory rate >30 are tagged Red. If breathing is <30, proceed to the next step.
This identifies immediate respiratory life threats versus non-salvageable cases.
3
Assess circulatory perfusion via radial pulse or capillary refill.
An absent radial pulse or capillary refill >2 seconds results in an Immediate (Red) tag. If normal, proceed to the final step.
An absent radial pulse signals decompensated shock (systolic BP roughly <80 mmHg) and impending circulatory collapse, requiring immediate lifesaving intervention like hemorrhage control.
4
Check mental status.
Inability to follow simple commands results in a Red tag. The ability to follow commands results in a Yellow tag.
Altered mental status can indicate severe hypoxia or traumatic brain injury.

Following a percutaneous liver biopsy, the client is transferred back to the medical-surgical unit. To decrease the risk of internal hemorrhage, what is the most appropriate position for this client?

Show answer & explanation

Answer: Right side-lying position with a small pillow or towel roll under the puncture site

Answer

The right side-lying position with a small pillow or towel roll under the puncture site.
The right side-lying position utilizes the client's own body weight and gravity to apply direct pressure over the liver and the puncture site. This creates a mechanical tamponade effect that promotes hemostasis and significantly minimizes the risk of hemorrhage, which is the most critical and life-threatening complication following a liver biopsy.

Step-by-Step Solution

1
Recall the anatomical location of the liver and its vascular nature.
The liver is highly vascular and located on the right side of the abdomen.
Understanding anatomy is essential to anticipate post-procedure risks.
2
Identify the primary complication associated with a percutaneous liver biopsy.
Hemorrhage (internal bleeding) is the most critical immediate post-procedure risk.
The needle insertion creates a puncture in a vascular organ.
3
Determine the physiological mechanism to prevent bleeding at a puncture site.
Applying direct external pressure creates a tamponade effect to promote hemostasis.
Pressure stops bleeding and allows clots to form.
4
Select the position that applies this physiological mechanism.
The right side-lying position places the client's body weight over the right-sided puncture site.
This utilizes gravity and body weight to compress the liver capsule.

Key Concept

Post-procedure hemorrhage risk reduction via physiological tamponade.

A nurse is caring for an older adult client who is experiencing acute confusion and repeatedly attempting to pull out their peripheral intravenous (IV) catheter. Which action should the nurse take to maintain patient safety and prevent injury?

Show answer & explanation

Answer: Cover the IV insertion site with a continuous tubular bandage to conceal it from the client's view

Answer

The correct action is to cover the IV insertion site with a continuous tubular bandage to conceal it from the client's view.
Nursing standards of care require the implementation of the least restrictive measures possible before applying any form of physical restraint. Concealing medical devices, such as an IV catheter, using a stockinette, long sleeves, or a continuous tubular bandage is an effective, non-restrictive alternative. It often decreases a confused client's visual fixation on the device, thereby preventing self-injury without limiting the client's mobility or violating their autonomy.

Step-by-Step Solution

1
Identify the primary safety risk presented in the scenario.
The client is at risk for self-injury and loss of vascular access due to acute confusion and pulling behavior.
Recognizing the specific hazard is the first step in formulating a targeted safety plan.
2
Evaluate potential interventions based on restrictiveness and scope of practice.
Concealing the IV site is a non-restrictive alternative. Restraints are highly restrictive. Assessing confusion requires nursing judgment.
Nursing standards mandate using the least restrictive intervention first and strictly prohibit delegating assessments to unlicensed personnel.
3
Select the most appropriate, least restrictive action.
Covering the IV site is chosen as the initial safety intervention.
This effectively mitigates the risk of self-injury by removing the visual trigger, without inappropriately restricting the client's movement or making unsafe clinical assumptions.

Pair the following admitted clients and their diagnoses with the specific infection control precaution category required by current guidelines.

Click a left item, then click its matching right item

Items

A client with disseminated herpes zoster (shingles) across multiple dermatomes
A child experiencing paroxysmal coughing fits from confirmed Bordetella pertussis
A client with a draining sacral pressure injury colonized with vancomycin-resistant Enterococcus (VRE)
A client with advanced HIV admitted for treatment of Pneumocystis jirovecii pneumonia (PJP)

Matches

Show answer & explanation

Answer

Disseminated herpes zoster matches with Airborne and Contact Precautions. Bordetella pertussis matches with Droplet Precautions. VRE wound colonization matches with Contact Precautions. Pneumocystis jirovecii pneumonia (PJP) matches with Standard Precautions.
Each pathogen or clinical condition dictates specific isolation measures based on its primary mode of transmission. Disseminated herpes zoster can spread via aerosols and direct contact. Pertussis spreads through large respiratory droplets. VRE is a multidrug-resistant organism spread by direct contact with the patient or contaminated surfaces. PJP is an opportunistic infection that is not communicable between humans, meaning routine standard precautions are sufficient.

Step-by-Step Solution

1
Analyze the transmission route of disseminated herpes zoster.
Requires both airborne and contact isolation.
The virus can be aerosolized and transmitted via contact with vesicular fluid.
2
Identify the transmission route for Bordetella pertussis.
Requires droplet isolation.
The pathogen is expelled in large respiratory droplets during coughing paroxysms.
3
Determine the precautions for a VRE-colonized draining wound.
Requires contact isolation.
Multidrug-resistant organisms in wounds are easily spread via direct contact or fomites.
4
Evaluate the infectivity of Pneumocystis jirovecii.
Requires only standard precautions.
It is an environmental fungus that causes opportunistic infection in immunocompromised hosts, but does not spread from person to person.

A client with severe acute pancreatitis is receiving total parenteral nutrition (TPN) and a separate intravenous lipid emulsion via a multi-lumen peripherally inserted central catheter (PICC). Which nursing actions are required for the safe administration and monitoring of these parenteral therapies? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Dedicate a single lumen of the central venous catheter exclusively for the TPN infusion.; Connect the intravenous lipid emulsion tubing below the 0.220.22-micron TPN inline filter.; Assess the client for sudden fever and coagulation abnormalities indicating fat overload syndrome.

Answer

The correct actions involve dedicating a single lumen exclusively for TPN, connecting the lipid emulsion below the standard inline filter, and assessing the client for fat overload syndrome.
Safe parenteral nutrition administration demands strict adherence to physical compatibility and infection control protocols. A dedicated central lumen is mandatory to prevent chemical incompatibilities that cause life-threatening precipitates. Because lipid particles are physically larger than the pores in a standard 0.220.22-micron TPN filter, the lipid emulsion must be attached below the filter to prevent mechanical occlusion. Furthermore, expert nursing care involves continuously monitoring for rare but severe physiological reactions to parenteral lipids, such as fat overload syndrome, which presents with fever, coagulopathy, and hepatosplenomegaly.

Step-by-Step Solution

1
Evaluate the requirement for central line dedication.
Identify that TPN requires an absolutely dedicated lumen.
TPN is a hypertonic, high-glucose solution that is highly susceptible to precipitation when mixed with other intravenous drugs. Piggybacking medications into this line compromises patient safety.
2
Analyze the physical properties of lipid emulsions relative to standard TPN filters.
Determine that the lipid emulsion must bypass the standard 0.220.22-micron filter used for the amino acid/dextrose solution.
Lipid droplets have a larger particle size than the filter pores. Pushing them through a standard bacterial filter will occlude the filter and destabilize the emulsion. They must connect at a Y-site closer to the patient, below the filter.
3
Identify potential adverse systemic effects of intravenous lipid administration.
Recognize the signs of fat overload syndrome.
While rare, lipid emulsions can cause fat overload syndrome, requiring the nurse to monitor for acute signs like fever, hyperlipidemia, and coagulopathy.
4
Determine the correct infection control protocols and complication management for TPN.
Recognize that tubing must be changed every 2424 hours and that TPN should never be stopped abruptly for hyperglycemia.
Standard 7272-hour IV tubing changes do not apply to high-glucose nutrient solutions due to rapid bacterial proliferation. Abrupt cessation causes profound reactive hypoglycemia.

Key Concept

Advanced management of Total Parenteral Nutrition (TPN) and intravenous lipids, focusing on mechanical administration safety and physiologic complication monitoring.
