An order is written for liquid acetaminophen at $15 \text{ mg/kg}$ per dose for a toddler who weighs $16 \text{ kg}$ . The medication bottle is labeled $160 \text{ mg}/5 \text{ mL}$ . Calculate the total volume in $\text{mL}$ that should be administered for a single dose. (Record your answer to one decimal place.)

Cevabı ve açıklamayı göster

Cevap: 7.5

Cevap

7.5

The correct dose is found in two steps. First, find the total mg needed by multiplying the toddler's weight (

16 \text{ kg}

) by the prescribed amount (

15 \text{ mg/kg}

), which equals

240 \text{ mg}

. Second, use the concentration of the liquid medication to find the volume. Dividing the desired dose (

240 \text{ mg}

) by the on-hand dose (

160 \text{ mg}

) and multiplying by the volume (

5 \text{ mL}

) yields exactly

7.5 \text{ mL}

Adım Adım Çözüm

Calculate the total required dose in milligrams.

16 \text{ kg} \times 15 \text{ mg/kg} = 240 \text{ mg}

The prescription is weight-based, meaning the patient's exact weight must be multiplied by the prescribed weight-based dosage.

Determine the required liquid volume using the supplied medication concentration.

(240 \text{ mg} / 160 \text{ mg}) \times 5 \text{ mL} = 7.5 \text{ mL}

Using the standard formula (Desired Dose / Available Dose) × Available Volume, the calculated milligram requirement is converted into the volume to be administered.

A nurse is caring for a laboring client at 37 weeks gestation who has severe preeclampsia. The provider has prescribed a strict total fluid restriction of $125\text{ mL/hr}$ , which includes all oral and intravenous (IV) intake.

The client is receiving a continuous IV infusion of magnesium sulfate at a rate of $2\text{ g/hr}$ . The magnesium sulfate is supplied as $40\text{ g}$ in $1,000\text{ mL}$ of sterile water. The client also has a continuous IV infusion of oxytocin running at $15\text{ mL/hr}$ . Over the past 4 hours, the client has consumed $4\text{ oz}$ of ice chips and $120\text{ mL}$ of water.

Assuming the oral intake is distributed evenly across the 4 hours, what is the maximum rate in $\text{mL/hr}$ at which the nurse should program the primary IV pump to deliver lactated Ringer's solution? (Record your answer as a whole number.)

Cevap: 15

Cevap

Clients with severe preeclampsia are at high risk for pulmonary edema and require strict fluid restriction, typically limited to

125\text{ mL/hr}

from all sources. To calculate the remaining allowable fluid for the primary IV, the nurse must sum all current hourly intakes and subtract this from the

125\text{ mL/hr}

limit.

First, calculate the magnesium sulfate rate:

40\text{ g}

1,000\text{ mL}

yields a concentration of

0.04\text{ g/mL}

. The prescribed rate is

2\text{ g/hr}

, which requires

50\text{ mL/hr}

(

2 \div 0.04

).

Second, determine the hourly oral intake. The client consumed

4\text{ oz}

of ice chips, which equals

120\text{ mL}

. Because ice chips melt to half their volume, this counts as

60\text{ mL}

of intake. Added to the

120\text{ mL}

of water, the total oral intake is

180\text{ mL}

over 4 hours, resulting in an average of

45\text{ mL/hr}

.

The total current intake is

50\text{ mL/hr}

(magnesium) +

15\text{ mL/hr}

(oxytocin) +

45\text{ mL/hr}

(oral fluids) =

110\text{ mL/hr}

.

Finally, subtract this from the restriction limit:

125\text{ mL/hr} - 110\text{ mL/hr} = 15\text{ mL/hr}

. The primary IV should be set at a maximum of

15\text{ mL/hr}

Adım Adım Çözüm

Calculate the IV rate for the magnesium sulfate infusion.

50\text{ mL/hr}

The concentration is

40\text{ g}

1,000\text{ mL}

(or

0.04\text{ g/mL}

). The prescribed dose is

2\text{ g/hr}

. Therefore,

2\text{ g/hr} \div 0.04\text{ g/mL} = 50\text{ mL/hr}

Calculate the total volume of oral intake over the 4-hour period.

180\text{ mL}

Standard conversion:

1\text{ oz} = 30\text{ mL}

4\text{ oz}

of ice chips =

120\text{ mL}

. Ice chips melt to half their volume, providing

60\text{ mL}

of fluid. Adding the

120\text{ mL}

of water gives a total of

180\text{ mL}

(

60\text{ mL} + 120\text{ mL}

Calculate the average hourly oral intake.

45\text{ mL/hr}

The

180\text{ mL}

of oral intake was consumed over 4 hours.

180\text{ mL} \div 4\text{ hr} = 45\text{ mL/hr}

Calculate the total current hourly fluid intake.

110\text{ mL/hr}

Add the rates of all current intake sources:

50\text{ mL/hr}

(magnesium) +

15\text{ mL/hr}

(oxytocin) +

45\text{ mL/hr}

(oral fluids) =

110\text{ mL/hr}

Determine the maximum rate for the primary IV lactated Ringer's.

15\text{ mL/hr}

Subtract the current total intake from the strict restriction limit:

125\text{ mL/hr} - 110\text{ mL/hr} = 15\text{ mL/hr}

Cevap: Auscultate breath sounds and assess oxygen saturation prior to initiating endotracheal suctioning; Maintain the client's upper body in a semi-Fowler's alignment to prevent ventilator-associated complications

Cevap

The appropriate interventions are to auscultate breath sounds prior to endotracheal suctioning and to maintain the client's upper body in a semi-Fowler's alignment.

The correct actions focus on evidence-based risk reduction strategies for mechanically ventilated clients. Assessing lung sounds before suctioning prevents unnecessary trauma and hypoxia, while maintaining an elevated upper body reduces the risk of aspiration and ventilator-associated pneumonia. These actions directly mitigate physiological risks.

Adım Adım Çözüm

Analyze the arterial blood gas (ABG) results.

The pH is 7.28 (acidosis), PaCO2 is 62 mm Hg (respiratory), and HCO3 is 24 mEq/L (normal), indicating uncompensated respiratory acidosis.

Accurate interpretation dictates the correct clinical interventions and prevents the administration of inappropriate treatments like sodium bicarbonate.

Evaluate positioning requirements for a mechanically ventilated client.

The client requires an elevated upper body.

A semi-Fowler's alignment reduces the risk of aspiration and ventilator-associated pneumonia, whereas a flat position is contraindicated.

Apply the airway, breathing, and circulation (ABC) prioritization framework.

Airway and ventilation issues must be addressed before routine care.

A high-pressure ventilator alarm indicates a life-threatening airway compromise that takes absolute precedence over hygiene.

Cevabı ve açıklamayı göster

Cevap: Removing one restraint at a time every 2 hours to provide skin care, perform passive range of motion, and evaluate the client's behavior.

Cevap

The nurse should remove one restraint at a time every 2 hours to provide skin care, perform range of motion, and evaluate the client's ongoing need for the restraints.

For non-violent (medical-surgical) restraints, the standard of care requires the nurse to temporarily release the restraints at least every 2 hours. This must be done one extremity at a time to maintain safety. During this release, the nurse must provide skin care, perform passive range-of-motion exercises, assess neurovascular status (pulses, color, temperature, sensation), and evaluate if the client's behavior indicates the restraints can be safely discontinued.

Adım Adım Çözüm

Analyze the client's clinical situation and the type of restraint ordered.

The client has non-violent (medical-surgical) soft wrist restraints applied to prevent the removal of life-sustaining medical devices (pacing wires and chest tubes).

Identifying the restraint category dictates the specific regulatory timeline for assessment, release, and prescription renewal.

Evaluate each nursing intervention against evidence-based safety and regulatory standards.

Tying restraints to side rails causes injury. PRN restraint orders are illegal. Delegating clinical assessments to a UAP violates the nurse practice act.

Eliminating unsafe practices isolates the correct evidence-based nursing action.

Identify the standard of care for maintaining client safety while restrained.

Releasing the restraints sequentially every 2 hours allows for necessary skin and circulatory care while maintaining the client's overall safety.

This action balances the need for device protection with the client's physiological needs and comfort.

Cevap

The correct sequence is to first stop the transfusion, then disconnect the blood tubing, attach new tubing primed with 0.9% sodium chloride, assess the client's status, notify the provider and blood bank, and finally send the equipment to the blood bank for testing.

The correct sequence prioritizes immediate patient safety by stopping the administration of the offending agent, physically disconnecting it, and securing venous access with a new line. Only after these lifesaving actions are complete should the nurse gather assessment data to communicate with the medical team, and finally preserve the evidence for laboratory investigation.

Adım Adım Çözüm

Stop the blood transfusion.

The infusion of the potentially incompatible blood product is halted.

This is the most critical first step to prevent further physiological harm to a client experiencing an acute hemolytic reaction.

Disconnect the blood administration set from the intravenous hub.

The source of the incompatible blood is physically separated from the client's vascular access.

This prevents inadvertently pushing the remaining blood in the tubing into the client during the subsequent flush.

Attach a new intravenous tubing primed with 0.9% sodium chloride.

A patent intravenous line is secured with a compatible isotonic fluid.

Intravenous access must be maintained for potential emergency interventions, fluid resuscitation, and blood pressure support.

Assess the client's vital signs and clinical status.

Objective data regarding the severity of the reaction is gathered.

The nurse must evaluate the client's respiratory, hemodynamic, and neurological status to provide accurate and current information to the healthcare provider.

Notify the primary healthcare provider and the blood bank.

The medical team is alerted, and further emergency orders can be obtained.

The provider needs the assessment data to prescribe interventions (e.g., epinephrine, vasopressors, antihistamines), and the blood bank must initiate a reaction investigation.

Send the discontinued blood bag and administration set to the blood bank.

The suspected blood product is transported for laboratory analysis.

Cevabı ve açıklamayı göster

Cevap: 15.3

Cevap

15.3

To safely administer a weight-based continuous intravenous infusion, the nurse must first establish the client's weight in kilograms (

187 \text{ lbs} \div 2.2 = 85

kg). The weight is then multiplied by the ordered dose to find the hourly medication requirement (

85 \text{ kg} \times 18 \text{ units/kg/hr} = 1530 \text{ units/hr}

). Finally, the nurse determines the fluid volume needed to deliver this dose by dividing the hourly requirement by the concentration of the IV solution (

25,000 \text{ units} \div 250 \text{ mL} = 100 \text{ units/mL}

). Therefore,

1530 \text{ units/hr} \div 100 \text{ units/mL} = 15.3 \text{ mL/hr}

Adım Adım Çözüm

Convert weight to kilograms.

85 kg

The prescribed dose is weight-based in kg, so the client's weight in lbs must be converted by dividing by 2.2.

Calculate the hourly heparin dose.

1530 units/hr

Multiplying the client's weight in kg by the prescribed hourly dose of 18 units/kg/hr provides the total required units per hour.

Calculate the volume rate of the infusion.

Cevabı ve açıklamayı göster

Cevap: Serum potassium level of $3.1$ mEq/L ( $3.1$ mmol/L)

Cevap

The correct finding that requires immediate intervention is the serum potassium level of 3.1 mEq/L (3.1 mmol/L).

Intravenous regular insulin effectively lowers blood glucose levels by allowing glucose to enter the cells. However, a major physiological consequence of this therapy is that it actively drives potassium out of the intravascular space and into the intracellular space, rapidly depleting serum potassium levels. A serum potassium level of

3.1

mEq/L indicates clinically significant hypokalemia (normal range is

3.5

5.0

mEq/L). Because severe hypokalemia places the client at an immediate risk for life-threatening cardiac dysrhythmias (such as ventricular fibrillation), the nurse must promptly intervene by alerting the provider and preparing to administer supplemental intravenous potassium to reduce the risk of a fatal complication.

Adım Adım Çözüm

Analyze the physiological effect of the prescribed therapy (intravenous insulin) on the client's cellular metabolism.

Intravenous insulin drives glucose out of the bloodstream and into the cells, but it also actively drives potassium into the intracellular space.

Understanding the side effects of DKA treatment is critical to anticipating potential complications.

Evaluate the provided laboratory values against normal reference ranges.

The potassium level of 3.1 mEq/L is critically below the normal range of 3.5 to 5.0 mEq/L, indicating hypokalemia.

Identifying which lab values are outside normal limits is the first step in clinical decision-making.

Prioritize the abnormal findings based on the ABCs (Airway, Breathing, Circulation) and immediate threat to life.

Hypokalemia poses a severe and immediate risk for fatal cardiac dysrhythmias (Circulation), making it the highest priority over expected dehydration or resolving acidosis.

Risk reduction requires the nurse to address the most acutely life-threatening complication first.

Cevap

The findings indicating the progressive stage of hypovolemic shock are a MAP of 54 mm Hg, an ABG showing metabolic acidosis (pH 7.22, HCO3- 14 mEq/L), and severe oliguria (10 mL/hr).

The progressive (uncompensated) stage of shock is characterized by the failure of compensatory mechanisms to maintain adequate tissue perfusion. A mean arterial pressure (MAP) below

65\text{ mm Hg}

indicates significant hypotension and loss of hemodynamic compensation. Tissue hypoxia forces cells into anaerobic metabolism, producing lactic acid and resulting in severe metabolic acidosis (pH

7.22

\text{HCO}_3^-

14\text{ mEq/L}

). Additionally, severe vasoconstriction and hypoperfusion to the kidneys cause profound oliguria, such as a urine output of

10\text{ mL/hr}

Adım Adım Çözüm

Analyze the client's clinical scenario.

The client has a severe hemorrhage leading to hypovolemia. The task is to identify signs of progressive (uncompensated) shock.

Understanding the sequential stages of shock is necessary to differentiate early compensatory signs from late progressive signs.

Evaluate the hemodynamic parameters.

A MAP below 65 mm Hg (e.g., 54 mm Hg) indicates failure of compensatory mechanisms and inadequate tissue perfusion.

Compensatory mechanisms initially maintain blood pressure; profound hypotension marks the transition to the progressive stage.

Interpret the arterial blood gas (ABG) values.

A pH of 7.22 with an HCO3- of 14 mEq/L indicates uncompensated metabolic acidosis, typical of progressive shock. A pH of 7.45 indicates alkalosis, which is an early compensatory sign.

Anaerobic metabolism in progressive shock generates lactic acid, leading to severe metabolic acidosis.

Assess organ perfusion indicators such as urine output and pulse pressure.

Urine output of 10 mL/hr reflects severe renal hypoperfusion. Pulse pressure typically narrows in hypovolemic shock, not widens.

Oliguria is a classic sign of progressive shock due to the shunting of blood away from the kidneys.

Anahtar Kavram

In the progressive (uncompensated) stage of hypovolemic shock, compensatory mechanisms fail, leading to significant hypotension (MAP < 65 mm Hg), altered tissue perfusion (profound oliguria), and anaerobic metabolism causing metabolic acidosis.

Cevap: Suspend the continuous oxytocin infusion, assist the client into a lateral position, and administer an isotonic fluid bolus.

Cevap

The most critical intervention is to suspend the continuous oxytocin infusion, assist the client into a lateral position, and administer an isotonic fluid bolus.

The scenario describes late decelerations, which are characterized by a gradual decrease in the fetal heart rate that reaches its lowest point after the peak of the uterine contraction. This pattern indicates uteroplacental insufficiency and potential fetal hypoxia. The immediate priority is intrauterine resuscitation to improve placental blood flow and fetal oxygenation. This involves a sequence of actions often remembered by the acronym POISE or similar protocols: stopping the oxytocin (to reduce uterine activity), positioning the client laterally (to relieve aortocaval compression), increasing intravenous fluids (to optimize maternal cardiac output), and administering oxygen.

Adım Adım Çözüm

Analyze the fetal heart rate tracing described in the scenario.

The gradual decrease in fetal heart rate with the nadir occurring after the peak of the contraction identifies the pattern as late decelerations.

Accurate pattern recognition is necessary to determine the underlying physiological cause.

Determine the pathophysiological cause of late decelerations.

Late decelerations are caused by uteroplacental insufficiency, meaning the fetus is experiencing transient hypoxemia during contractions.

Understanding the cause dictates the appropriate clinical interventions to restore adequate oxygenation.

Select the appropriate nursing interventions for intrauterine resuscitation.

The nurse must improve placental blood flow and oxygenation by stopping the oxytocin (which causes the contractions), repositioning the client laterally (to relieve vena cava compression), and administering an IV fluid bolus (to increase maternal blood volume).

These combined actions directly address the uteroplacental insufficiency and prevent further fetal compromise.

Cevap: Place a standard medical-surgical mask on the client before exiting the isolation room.; Perform hand hygiene using soap and water immediately after removing gloves.; Cover the client with a clean sheet or blanket over their hospital gown prior to entering the hallway.

Cevap

The correct actions are placing a standard medical-surgical mask on the client, performing hand hygiene with soap and water, and covering the client with a clean sheet or blanket during transport.

Transporting a client with multiple infections requires layering protective strategies. A standard surgical mask on the client effectively contains tuberculosis respiratory secretions without compromising the client's breathing. Covering the client with a clean sheet contains C. diff organisms to the stretcher environment. Finally, because C. diff forms spores that are resistant to alcohol, staff must strictly use soap and water for hand hygiene.

Adım Adım Çözüm

Identify the transmission-based precautions required for the client's concurrent infections.

The client requires Airborne Precautions for active pulmonary tuberculosis and Contact/Enteric Precautions for Clostridioides difficile.

Accurate identification of required isolation categories dictates the specific interventions needed during transport.

Apply Airborne Precaution guidelines for client transport.

The client must wear a standard medical-surgical mask to contain respiratory secretions.

Airborne pathogens are expelled through coughing or exhaling. A standard mask effectively traps these source droplets before they evaporate into airborne nuclei.

Apply Contact/Enteric Precaution guidelines for client transport and environmental cleaning.

The client must be covered with a clean sheet, hand hygiene must be performed with soap and water, and equipment must be cleaned with sporicidal wipes.

Contact precautions require preventing environmental contamination during transport. Enteric precautions specifically mandate soap and water and bleach-based disinfectants because spores are resistant to alcohol and standard germicides.

Evaluate the clinical priority of the diagnostic test against infection control risks.

The urgent CT scan must proceed with strict precautions in place.

Cevap: Instruct all personnel to don a surgical mask upon entering the client's room.; Keep a dedicated stethoscope and blood pressure cuff inside the client's room.; Apply a standard surgical mask to the client when transport to the radiology department is necessary.

Cevap

The correct interventions include instructing personnel to wear a surgical mask, leaving dedicated equipment in the room, and placing a surgical mask on the client during transport.

The client requires a combination of Droplet and Contact precautions. Droplet precautions mandate that healthcare personnel wear a surgical mask upon entry and that the client wears one during transport to contain respiratory secretions. Contact precautions require the use of dedicated patient-care equipment to prevent indirect transmission of the pathogen to other clients via shared tools.

Adım Adım Çözüm

Analyze the client's diagnoses and determine the required isolation categories.

Hib pneumonia requires Droplet precautions. VRE wound infection requires Contact precautions.

Accurate identification of transmission routes dictates the necessary personal protective equipment (PPE) and environmental controls.

Select interventions that align with Droplet precautions.

Identified the need for staff to wear surgical masks upon entry and for the client to wear a surgical mask during transport.

Droplet precautions target large respiratory particles that travel short distances, requiring barrier protection for the mucous membranes of nearby individuals.

Select interventions that align with Contact precautions.

Identified the need to dedicate reusable, non-critical equipment (stethoscope, blood pressure cuff) to the client's room.

Contact precautions prevent transmission of multidrug-resistant organisms spread through direct patient contact or indirect contact with contaminated environmental surfaces.

Evaluate the remaining options for clinical and delegation inaccuracies.

Eliminated the negative-pressure room (only for Airborne), exclusive soap-and-water handwashing (only for spore-forming organisms), and delegating wound assessment to UAP (outside scope of practice).

Ensures adherence to evidence-based infection control standards and safe delegation guidelines.

Anahtar Kavram

Clients with multiple transmissible infections require a combination of precautions. Droplet precautions require surgical masks for staff and for the client during transport. Contact precautions necessitate dedicated equipment and proper hand hygiene, though alcohol-based rubs remain acceptable unless spore-forming organisms are present.

Following a total thyroidectomy, an adult client is admitted to the surgical step-down unit. To minimize the potential for severe postoperative complications, which actions and assessments must the nurse include in the plan of care? Select all that apply.

Geçerli olan tümünü seçin

Maintain the client in a semi-Fowler's position with the head and neck supported by pillows.

Verify that a tracheostomy tray, oxygen, and suction equipment are present at the bedside.

Encourage the client to actively extend and flex the neck to prevent postoperative muscle stiffness.

Monitor the client for reports of circumoral numbness, tingling, or muscle twitching.

Delegate the hourly evaluation of the client's voice quality and swallowing ability to the nursing assistant.

Delay inspecting the posterior neck for bleeding as long as the anterior surgical dressing remains dry.

Cevap: Maintain the client in a semi-Fowler's position with the head and neck supported by pillows.; Verify that a tracheostomy tray, oxygen, and suction equipment are present at the bedside.; Monitor the client for reports of circumoral numbness, tingling, or muscle twitching.

Cevap

The correct interventions include maintaining a semi-Fowler's position with neck support, ensuring emergency airway equipment is at the bedside, and monitoring for signs of hypocalcemia such as circumoral numbness.

Following a thyroidectomy, clients are at extremely high risk for airway compromise, hemorrhage, and hypocalcemia. Maintaining a semi-Fowler's position reduces edema and minimizes tension on the anterior neck incision. Having a tracheostomy tray and suction equipment readily available is essential for immediate airway management if a rapid hematoma develops. Furthermore, monitoring for circumoral numbness or muscle twitching allows for early detection of hypocalcemia, a common complication resulting from inadvertent parathyroid gland injury.

Adım Adım Çözüm

Identify the primary life-threatening complications associated with a total thyroidectomy.

The major risks are airway obstruction (from edema or hematoma), severe hemorrhage, and acute hypocalcemia (from parathyroid damage).

Understanding the specific risks guides the nurse in prioritizing appropriate reduction strategies.

Determine the optimal positioning to reduce surgical site complications.

The client should be placed in a semi-Fowler's position with the head and neck carefully supported by pillows or sandbags.

This position promotes venous return to reduce swelling and prevents hyper-extension of the neck, which could tear the suture line.

Select interventions that prepare for sudden airway emergencies.

A tracheostomy tray, suction equipment, and oxygen must be immediately accessible at the bedside.

If a hematoma rapidly expands and compresses the trachea, an emergency tracheostomy may be required to save the client's life.

Identify early clinical markers of parathyroid gland injury.

The nurse must assess for circumoral numbness, tingling in the extremities, and muscle twitching (Chvostek's or Trousseau's signs).

Inadvertent removal or trauma to the parathyroid glands during surgery causes a sudden drop in serum calcium, requiring immediate calcium gluconate administration.

Following a positive sputum acid-fast bacillus (AFB) smear, an adult client is placed in an airborne infection isolation room. As the care team coordinates daily care, which specific precautions must be enforced? (Select all that apply.)

Geçerli olan tümünü seçin

Ensure the isolation room maintains negative pressure with at least 6 to 12 air changes per hour.

Place a standard surgical mask over the client's mouth and nose when transport outside the room is necessary.

Require all healthcare personnel to don a fit-tested N95 respirator or PAPR prior to entering the client's room.

Delegate the initial education regarding cough etiquette and respiratory hygiene to the unlicensed assistive personnel.

Discontinue airborne precautions once the client completes 24 hours of appropriate antitubercular pharmacotherapy.

Keep the client's room door propped open slightly to promote continuous air circulation with the hallway.

Cevap: Ensure the isolation room maintains negative pressure with at least 6 to 12 air changes per hour.; Place a standard surgical mask over the client's mouth and nose when transport outside the room is necessary.; Require all healthcare personnel to don a fit-tested N95 respirator or PAPR prior to entering the client's room.

Cevap

The correct interventions are maintaining negative pressure with 6-12 air changes per hour, placing a surgical mask on the client during transport, and requiring all healthcare personnel to wear an N95 respirator or PAPR before entering.

Active pulmonary tuberculosis requires strict airborne precautions because the pathogen is transmitted via very small droplet nuclei that remain suspended in the air. Proper management involves placing the client in a negative-pressure Airborne Infection Isolation Room (AIIR) with 6 to 12 air changes per hour. Furthermore, all personnel must wear respiratory protection (N95 or PAPR) when entering the space, and the client must wear a standard surgical mask to contain their own respiratory secretions during any essential transport.

Adım Adım Çözüm

Analyze the client's clinical data and diagnosis.

The client has a positive AFB smear, which confirms active pulmonary tuberculosis.

Identifying the specific pathogen and its mode of transmission dictates the appropriate tier of transmission-based precautions.

Determine the required isolation category based on the pathogen.

Tuberculosis requires Airborne Precautions because it is transmitted via aerosolized droplet nuclei.

Airborne pathogens can remain suspended in the air for long periods and travel over long distances.

Evaluate each option against Airborne Precaution standards and delegation rules.

Negative pressure rooms, N95 respirators for staff, and surgical masks for client transport are standard protocols. Propping the door open, early discontinuation of precautions, and delegating initial teaching are incorrect.

Strict adherence to infection control parameters prevents healthcare-associated transmission, while safe delegation ensures competent care delivery.

Mid-morning on a high-acuity infectious disease ward, the charge nurse must dynamically adjust client assignments for a multi-disciplinary team. The current staffing includes a registered nurse (RN), a licensed practical nurse (LPN/VN), and unlicensed assistive personnel (UAP). Which task reallocation represents the safest application of delegation principles?

Transitioning the care of a client with a resolving methicillin-resistant Staphylococcus aureus (MRSA) wound infection to the LPN/VN to administer scheduled oral antibiotics and perform a sterile dressing change.

Reassigning the LPN/VN to assume primary care for a client who recently returned from a thoracentesis and is suddenly manifesting tachycardia, tachypnea, and a narrowing pulse pressure.

Directing the UAP to provide hygiene care for a client newly diagnosed with disseminated herpes zoster (shingles) without verifying the UAP's immunity status or issuing an N95 respirator.

Instructing the UAP to evaluate a client's balance and readiness to independently ambulate with a new assistive device prior to the client's scheduled discharge.

Cevabı ve açıklamayı göster

Cevap: Transitioning the care of a client with a resolving methicillin-resistant Staphylococcus aureus (MRSA) wound infection to the LPN/VN to administer scheduled oral antibiotics and perform a sterile dressing change.

Cevap

The most appropriate delegation is assigning the LPN/VN to administer oral antibiotics and perform a sterile dressing change for the stable client with a resolving MRSA infection.

The correct answer involves assigning an LPN/VN to perform routine, standard procedures (oral medication administration and sterile dressing changes) for a client whose condition is explicitly stated as 'resolving.' Because the client is stable and the tasks do not require initial assessment or complex clinical judgment, this falls perfectly within the LPN/VN scope of practice.

Adım Adım Çözüm

Analyze the core principles of delegation and the legal scope of practice.

Identify that RNs cannot delegate assessment, teaching, clinical judgment, or evaluation (EAT). LPN/VNs can perform complex but routine skills (like sterile dressings) on stable clients. UAPs handle standard, non-invasive tasks.

Establishing the baseline rules of delegation is necessary to evaluate each option.

Evaluate the stability and needs of the client returning from a thoracentesis.

The client has tachycardia, tachypnea, and a narrowing pulse pressure, indicating acute deterioration (potential shock or pneumothorax). This requires an RN.

Unstable clients with unpredictable outcomes must remain under the direct care of a registered nurse.

Assess the infection control requirements for disseminated herpes zoster.

Disseminated shingles requires airborne and contact precautions. The UAP was not provided proper PPE (N95) or vetted for immunity, making the assignment unsafe.

Delegation includes ensuring the environment and instructions are safe for the personnel performing the task.

Review the task delegated to the UAP regarding ambulation.

The task asks the UAP to 'evaluate' readiness, which violates the rule against delegating evaluation or clinical judgment.

Only an RN or physical therapist can perform the initial assessment and evaluation of a client's ability to use a new assistive device safely.

Verify the appropriateness of the MRSA client assignment.

The client is stable ('resolving'). Oral medications and sterile dressing changes are within the LPN/VN scope, making this the only safe delegation.

Matching a stable client with predictable needs to the LPN/VN's skill set represents proper resource allocation.

Cevabı ve açıklamayı göster

Cevap

The correct sequence for removing (doffing) PPE is: remove gloves first, then the face shield, followed by the gown, the surgical mask, and finally perform hand hygiene.

According to standard Centers for Disease Control and Prevention (CDC) guidelines for PPE removal (doffing), the most contaminated items should be removed first to minimize the risk of self-contamination. Gloves are removed first, followed by eye protection (face shield or goggles). The gown is then removed, followed by the mask or respirator. Hand hygiene is absolutely required as the final step after all PPE has been removed.

Adım Adım Çözüm

Remove the contaminated gloves.

Hands are freed from the most highly contaminated item.

Prevents cross-contamination to the face, eyes, or clean areas of the body during subsequent removal steps.

Remove the face shield by the headband or ear pieces.

Eye and face protection is safely discarded.

The outside of the shield is contaminated; handling only the back straps prevents pathogen transfer to the bare hands.

Remove the disposable gown by pulling it away from the neck and shoulders.

Body protection is safely discarded.

The front and sleeves are heavily contaminated. Rolling it outward traps pathogens on the inside of the bundle.

Remove the surgical mask by grasping the ties or elastics.

Respiratory protection is safely discarded.

The mask is removed last to maintain respiratory and mucous membrane protection until all other contaminated items have been safely disposed of.

Perform hand hygiene with an alcohol-based rub or soap and water.

Hands are completely sanitized.

Eradicates any transient pathogens that may have inadvertently transferred to the hands during the doffing process.

Which of the following is the priority nursing action?

Escort the employee to a quiet, private room and remain present while offering a glass of water.

Assess the employee's past coping mechanisms for dealing with significant life changes.

Reassure the employee that their extensive work experience will help them find a new job quickly.

Cevap: Escort the employee to a quiet, private room and remain present while offering a glass of water.

Cevap

The correct action is to escort the employee to a quiet, private room and remain present while offering a glass of water.

During the initial phase of a crisis, the client's anxiety level is often severe to panic. The absolute priority is to ensure safety and physiological stabilization while decreasing environmental stimuli. Remaining present with the client in a quiet environment and providing a simple grounding action, such as offering a drink of water, addresses immediate Maslow's basic needs and helps de-escalate the panic state.

Adım Adım Çözüm

Analyze the client's current presentation.

The client is exhibiting signs of acute severe anxiety and panic (hyperventilation, rigidity, repetitive speech) due to a sudden situational crisis.

Identifying the current phase of the crisis determines the appropriate level of intervention required.

Apply crisis intervention prioritization principles.

Immediate physiological and psychological safety takes precedence over long-term planning, teaching, or psychosocial assessment.

A client in severe anxiety has a significantly narrowed perceptual field and cannot process new information or engage in problem-solving.

Select the intervention that directly addresses immediate stabilization.

Moving the client to a quiet area reduces environmental stimuli, and offering water addresses basic physiological needs while grounding the client.

This promotes immediate safety and de-escalation, laying the foundation for further therapeutic work.

Cevap: Assisting a clinically stable client who had an ischemic stroke three days ago with routine oral hygiene and turning.

Cevap

Assisting a clinically stable client who had an ischemic stroke three days ago with routine oral hygiene and turning.

The correct delegation decision involves assigning routine, predictable tasks that do not require nursing judgment to the unlicensed assistive personnel. Assisting a stable client with activities of daily living perfectly matches the UAP's scope of practice.

Adım Adım Çözüm

Analyze each client care activity to identify requirements for clinical judgment, assessment, evaluation, or teaching.

Evaluating swallowing, demonstrating crutch-walking, and conducting an admission assessment all require RN-level cognitive skills and licensure.

The National Council of State Boards of Nursing (NCSBN) explicitly prohibits the delegation of nursing judgment, assessment, and teaching to unlicensed personnel.

Determine the clinical stability and acuity of the clients described in each scenario.

The newly admitted client with sepsis is highly unstable, whereas the client who had an ischemic stroke three days ago is described as clinically stable.

Delegation is only appropriate for clients whose conditions are stable and whose care yields predictable outcomes.

Apply the Five Rights of Delegation to select the appropriate activity for the UAP.

Providing routine oral hygiene and assisting with turning for the stable stroke client is the only legally and clinically safe task to delegate.

This task involves routine activities of daily living (ADLs) that are standard within the UAP's training and do not require nursing judgment.

A nurse is performing a reassessment on a young adult client admitted with an acute asthma exacerbation. The client initially presented with marked tachypnea, use of accessory muscles, and loud bilateral wheezing. Thirty minutes later, the nurse observes that the client's respirations have become shallow, wheezing is no longer audible, and the client appears drowsy. Arterial blood gas (ABG) results reveal a $\text{pH}$ of $7.28$ , a $\text{PaCO}_2$ of $58\text{ mm Hg}$ , and an $\text{HCO}_3^-$ of $24\text{ mEq/L}$ . Which of the following is the priority nursing action?

Administer the prescribed PRN nebulized albuterol treatment immediately

Continue to monitor as the absence of wheezing indicates a positive response to initial therapy

Notify the rapid response team and gather supplies for endotracheal intubation

Prepare to administer a continuous intravenous infusion of sodium bicarbonate

Cevap: Notify the rapid response team and gather supplies for endotracheal intubation

Cevap

Notify the rapid response team and gather supplies for endotracheal intubation.

The combination of a 'silent chest' (absent wheezing with shallow respirations), drowsiness, and respiratory acidosis (

\text{pH}

7.28,

\text{PaCO}_2

58) in an asthma patient signifies profound muscle fatigue and impending respiratory failure. Immediate intubation and mechanical ventilation are required to save the client's life.

Adım Adım Çözüm

Analyze the physical assessment changes.

The client transitioned from tachypnea and loud wheezing to shallow respirations, no audible wheezing ('silent chest'), and drowsiness.

Sudden loss of wheezing with decreased level of consciousness indicates extreme muscle fatigue and complete airway obstruction, a medical emergency.

Interpret the arterial blood gas (ABG) results.

The pH is 7.28 (acidosis) and PaCO2 is 58 mm Hg (elevated), indicating uncompensated respiratory acidosis.

Early asthma exacerbations typically present with respiratory alkalosis due to hyperventilation. A shift to respiratory acidosis signifies that the client can no longer maintain adequate ventilation.

Determine the priority clinical intervention.

The nurse must immediately call for help and prepare for advanced airway management (intubation and mechanical ventilation).

The client is in impending respiratory failure. Airway and breathing take the highest priority, and pharmacological interventions will not be effective without adequate airflow.
