A young adult arrives at an outpatient clinic for a routine wellness check and is scheduled to receive the measles, mumps, and rubella (MMR) immunization. While filling out the pre-assessment questionnaire, the client mentions missing her last menstrual cycle and having a positive home pregnancy test three days ago. Based on these findings, which action should the practical nurse implement?

Show answer & explanation

Answer: Explain that this specific vaccine formulation is unsafe during pregnancy and report the information to the attending provider.

Answer

Explain that this specific vaccine formulation is unsafe during pregnancy and report the information to the attending provider.
The MMR vaccine is a live-attenuated virus. Administering it during pregnancy can lead to congenital rubella syndrome and other severe teratogenic effects. The practical nurse acts safely and within scope by identifying this absolute contraindication from the pre-assessment data, withholding the injection, and promptly reporting the client's potential pregnancy status to the healthcare provider.

Step-by-Step Solution

1
Analyze the client's current physiological status against the prescribed pharmacological therapy.
The client has a positive pregnancy test, and the prescribed medication is the MMR immunization.
Identifying potential contraindications is a critical safety step prior to administering any medication or biological agent.
2
Determine the safety profile of the specific vaccine during pregnancy.
The MMR vaccine is a live-attenuated virus formulation, which is strictly contraindicated during pregnancy due to documented teratogenic risks.
Live-attenuated viruses can cross the placental barrier and cause severe congenital anomalies.
3
Select the appropriate nursing intervention within the practical nurse scope of practice.
The practical nurse must withhold the immunization, reinforce to the client that it is unsafe, and alert the prescribing healthcare provider.
Ensuring client safety by holding contraindicated medications and communicating critical findings to the provider are foundational responsibilities of the practical nurse.

Key Concept

Live-attenuated vaccines (such as MMR and varicella) are strictly contraindicated during pregnancy due to the risk of severe congenital abnormalities. The practical nurse must routinely screen for pregnancy before administration, withhold the vaccine if pregnancy is suspected, and notify the healthcare provider.
Question 502Question →

A practical nurse is evaluating an adult client who underwent a percutaneous liver biopsy 22 hours prior. The client's baseline vital signs included a blood pressure of 124/78 mm Hg124/78\text{ mm Hg} and a heart rate of 76 beats/min76\text{ beats/min}. The nurse's current assessment reveals a blood pressure of 92/56 mm Hg92/56\text{ mm Hg} and a heart rate of 112 beats/min112\text{ beats/min}. The client reports feeling dizzy and having mild right shoulder pain. What is the priority nursing action?

Show answer & explanation

Answer: Alert the supervising registered nurse regarding the assessment findings.

Answer

Alert the supervising registered nurse regarding the assessment findings.
The client's presentation of tachycardia, hypotension, dizziness, and right shoulder pain (referred pain from diaphragmatic irritation) are classic signs of internal hemorrhage following a liver biopsy. The practical nurse must immediately escalate these findings to the registered nurse for prompt intervention, as the client is exhibiting signs of impending hypovolemic shock and compromised circulation. Addressing the circulatory collapse is the absolute highest priority.

Step-by-Step Solution

1
Analyze the current vital signs and compare them to the client's pre-procedure baseline.
The blood pressure has dropped significantly and the heart rate has increased, indicating new-onset hypotension and tachycardia.
Identifying trends and recognizing deviations from the baseline is essential for detecting post-procedural complications.
2
Evaluate the client's reported symptoms (dizziness and right shoulder pain) in the context of a recent liver biopsy.
The lightheadedness correlates with the hypotension, and the right shoulder pain is a classic sign of referred pain from blood irritating the diaphragm.
Synthesizing objective vital sign data with subjective symptoms determines the clinical severity of the situation.
3
Determine the priority nursing action based on the practical nurse's scope of practice.
The clinical picture strongly suggests hemorrhagic shock, requiring immediate escalation to the registered nurse rather than independent symptomatic management.
The LPN must advocate for client safety by prioritizing airway, breathing, and circulation (ABCs) and reporting critical changes that require RN assessment and provider intervention.

Question 503Question →

A practical nurse is preparing a client for a scheduled abdominal surgery. To reduce the risk of perioperative complications, which actions must the nurse ensure are completed before the client is transported to the operating room? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Verifying the client's adherence to the prescribed nothing-by-mouth (NPO) status.; Confirming the surgical consent document contains the client's signature.; Instructing the client to empty their bladder prior to receiving any preoperative sedatives.

Answer

The correct actions include verifying NPO status, confirming the surgical consent is signed, and instructing the client to empty their bladder before receiving preoperative sedatives.
Preoperative preparation focuses heavily on reducing intraoperative and postoperative risks. Verifying NPO status prevents aspiration during anesthesia. Confirming a signed consent protects the client's legal rights and verifies readiness. Having the client void before administering preoperative sedatives prevents falls (as the client should not get out of bed after sedation) and reduces the risk of bladder distention or injury during the surgical procedure.

Step-by-Step Solution

1
Identify the primary goal of the clinical scenario.
The goal is to determine appropriate practical nursing actions for preoperative risk reduction.
Understanding the phase of care (preoperative) helps identify which safety checklists and scope-of-practice rules apply.
2
Evaluate each potential action against the practical nurse's scope of practice and general safety protocols.
Verifying NPO status, confirming consent signatures, and having the client void are within scope and promote safety. Explaining surgical risks, administering IV push medications, and bypassing barcode scans are unsafe or out of scope.
Eliminating actions that violate foundational safety standards or exceed the licensed practical nurse's scope accurately isolates the correct choices.

Question 504Question →

A practical nurse (PN) is providing morning basic care for an older adult client on the third day following a partial gastrectomy. The client is receiving continuous enteral nutrition via a jejunostomy tube, requires extensive assistance with all personal hygiene, and has a documented history of early-stage dementia. Which interventions should the PN include in the client's plan of care? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Maintain the head of the bed elevated at 30 to 45 degrees while assisting the client with a bed bath and repositioning.; Cleanse the jejunostomy tube insertion site gently with warm water and mild soap during daily hygiene, patting the skin dry.; Apply a moisture-barrier ointment to the client's perineal area and sacrum following each episode of incontinence.

Answer

The correct actions are to maintain head-of-bed elevation during hygiene, cleanse the tube insertion site with mild soap and water, and apply moisture-barrier ointment after incontinence.
The correct interventions prioritize physiological safety and hygiene within the practical nursing scope. Maintaining a 30 to 45-degree elevation during care prevents aspiration of continuous feedings. Cleansing the jejunostomy site and applying perineal barrier creams are fundamental, evidence-based practices for preserving skin integrity in vulnerable, bedbound clients.

Step-by-Step Solution

1
Identify the client's primary risk factors based on the scenario.
The client is at high risk for aspiration (continuous enteral feeding), skin breakdown (incontinence, bed rest), and post-operative complications (gastrectomy).
Recognizing specific vulnerabilities directs the selection of safe basic care interventions.
2
Evaluate the safety of positioning during hygiene tasks.
The head of the bed must remain elevated to prevent aspiration; laying the client flat without pausing the feeding is contraindicated.
Continuous enteral nutrition requires airway protection at all times, including during bed baths and linen changes.
3
Differentiate between PN scope of practice and tasks requiring RN assessment.
Cleansing the stoma and applying barrier creams are within the PN scope, while evaluating swallowing ability for diet transition is an RN responsibility.
Nurses must strictly adhere to their legal scope of practice when implementing care.
4
Analyze the significance of the client's sudden agitation.
Sudden agitation is recognized as acute delirium or a physiological complication, not a normal progression of dementia.
Older adults are highly susceptible to acute delirium; attributing sudden changes to baseline dementia delays critical intervention.

Key Concept

Providing safe basic care and comfort requires synthesizing airway protection (aspiration precautions), maintaining skin integrity, recognizing acute cognitive changes, and adhering to the legal scope of practice.

Answer: 20

Answer

20
To calculate the correct volume to administer, use the standard formula: (Desired doseDose on hand)×Volume(\frac{\text{Desired dose}}{\text{Dose on hand}}) \times \text{Volume}. The desired dose is 400 mg400\text{ mg} and the dose on hand is 100 mg100\text{ mg} per 5 mL5\text{ mL}. Substituting these values into the formula gives (400 mg100 mg)×5 mL(\frac{400\text{ mg}}{100\text{ mg}}) \times 5\text{ mL}. Dividing 400400 by 100100 equals 44. Multiplying 44 by 5 mL5\text{ mL} yields the correct administration volume of 20 mL20\text{ mL}.

Step-by-Step Solution

1
Identify the desired dose prescribed by the provider.
Desired dose = 400 mg400\text{ mg}
This is the target amount of medication the client needs to receive.
2
Identify the dose on hand (concentration) and its corresponding volume.
Have = 100 mg100\text{ mg}, Quantity = 5 mL5\text{ mL}
This establishes the ratio of medication weight to liquid volume available from the pharmacy.
3
Apply the dosage calculation formula.
Formula: (DesiredHave)×Quantity(\frac{\text{Desired}}{\text{Have}}) \times \text{Quantity}
This formula converts the prescribed milligrams into the administrable milliliters.
4
Substitute the values into the formula and perform the calculation.
(400100)×5=4×5=20 mL(\frac{400}{100}) \times 5 = 4 \times 5 = 20\text{ mL}
Completing the math yields the exact volume to administer per dose.

Question 506Question →

An older adult client residing in a long-term care facility receives daily oral prednisone for rheumatoid arthritis. The healthcare provider newly prescribes oral levofloxacin to treat a respiratory infection. Which actions should the practical nurse implement to ensure safe pharmacological management? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Separate the administration of the levofloxacin and the client's daily calcium supplement by at least two hours.; Monitor the client closely for the sudden onset of heel or ankle pain and report it immediately.; Reinforce instructions for the client to wear protective clothing and apply sunscreen when spending time outdoors.

Answer

The correct actions are separating the antibiotic and calcium by two hours, monitoring for heel or ankle pain, and reinforcing the need for sun protection.
Safe pharmacological management requires understanding drug-specific adverse effects and interactions. Levofloxacin binds with multivalent cations like calcium, reducing absorption, so they must be separated. Fluoroquinolones carry a black box warning for tendon rupture, and this risk is exponentially higher in older adults concurrently taking corticosteroids like prednisone. Lastly, fluoroquinolones cause photosensitivity, making sun protection teaching essential.

Step-by-Step Solution

1
Analyze the drug classifications and potential interactions.
Levofloxacin is a fluoroquinolone antibiotic. Prednisone is a corticosteroid.
Identifying the drug classes highlights specific adverse effects and administration rules.
2
Evaluate the interaction between levofloxacin, corticosteroids, and client age.
The combination of advanced age, fluoroquinolones, and corticosteroids significantly increases the risk of tendon rupture.
This establishes the critical need to monitor for joint or tendon pain, specifically in the heel or ankle.
3
Identify general administration considerations for fluoroquinolones.
They interact with cations like calcium and cause photosensitivity.
This confirms the need to separate doses from calcium supplements and reinforce sun protection teaching.
4
Assess the remaining options for adherence to safety and scope of practice.
Using a room number for identification, evaluating the need for IV push medications, and normalizing acute confusion are all unsafe or out of scope.
Distractors must be eliminated based on established practical nursing standards and physiological principles.

Question 507Question →

A practical nurse is caring for a client with congestive heart failure who is scheduled to receive a morning dose of oral digoxin. The client's morning laboratory results show a serum potassium level of 3.0 mEq/L3.0\text{ mEq/L} (3.0 mmol/L3.0\text{ mmol/L}) and a serum digoxin level of 1.4 ng/mL1.4\text{ ng/mL} (1.8 nmol/L1.8\text{ nmol/L}). The client's apical pulse is 64 beats/min64\text{ beats/min}. During the morning assessment, the client reports new-onset severe nausea and seeing yellow halos around the lights in the room. Which action should the practical nurse take first?

Show answer & explanation

Answer: Withhold the digoxin dose and immediately report the client's symptoms and laboratory values to the supervising registered nurse.

Answer

The practical nurse must withhold the digoxin dose and immediately report the client's symptoms and laboratory values to the supervising registered nurse.
The correct action is to withhold the dose and notify the RN. The client's potassium level of 3.0 mEq/L3.0\text{ mEq/L} indicates hypokalemia. Low potassium increases the heart's sensitivity to digoxin, significantly elevating the risk of toxicity even when the serum digoxin level (1.4 ng/mL1.4\text{ ng/mL}) falls within the normal therapeutic range (0.5−2.0 ng/mL0.5-2.0\text{ ng/mL}). Furthermore, the client's nausea and visual disturbances (yellow halos) are classic clinical indicators of digoxin toxicity. The practical nurse must hold the medication and escalate these critical findings.

Step-by-Step Solution

1
Evaluate the client's laboratory results against normal reference ranges.
The serum potassium level is critically low (3.0 mEq/L3.0\text{ mEq/L}, normal is 3.5−5.0 mEq/L3.5-5.0\text{ mEq/L}), while the digoxin level is within the standard therapeutic range (0.5−2.0 ng/mL0.5-2.0\text{ ng/mL}).
Identifying abnormal laboratory values is essential before administering cardiovascular medications.
2
Correlate the client's physical symptoms and laboratory results with the prescribed medication.
Hypokalemia increases the myocardium's sensitivity to digoxin, leading to toxicity even at normal serum drug levels. Nausea and visual disturbances (yellow halos) are classic signs of digoxin toxicity.
Clinical presentation takes precedence over 'normal' therapeutic drug levels when predisposing factors like hypokalemia are present.
3
Determine the appropriate intervention within the practical nurse's scope of practice.
The nurse must withhold the medication to prevent further toxicity and immediately escalate the critical findings to the RN or provider.
Ensuring client safety by withholding a harmful medication and reporting to the RN aligns with the practical nursing scope of practice.

The primary health care provider has prescribed levothyroxine 0.125 mg0.125\text{ mg} orally once daily. The pharmacy supplies levothyroxine as scored tablets containing 50 mcg50\text{ mcg} per tablet. How many tablets should the nurse administer?

Record answer to the nearest tenth. Do not include units in answer.

Show answer & explanation

Answer: 2.5

Answer

2.5
To safely administer the correct dose, the practical nurse must ensure the prescribed dose and the supplied dose are in the same unit of measurement. Converting the prescribed 0.125 mg0.125\text{ mg} to micrograms yields 125 mcg125\text{ mcg}. Dividing the desired dose (125 mcg125\text{ mcg}) by the available dose (50 mcg50\text{ mcg} per tablet) results in 2.5 tablets2.5\text{ tablets}. Because the tablets are scored, it is safe and appropriate to administer two and a half tablets to achieve the prescribed dose.

Step-by-Step Solution

1
Convert the prescribed dose of levothyroxine from milligrams (mg) to micrograms (mcg) by multiplying by 1000.
0.125 mg×1000=125 mcg0.125\text{ mg} \times 1000 = 125\text{ mcg}
The prescribed dose and the supplied medication must be in the same unit of measurement before calculating the physical dosage.
2
Use the standard dosage calculation formula: Desired DoseAvailable Dose×Quantity\frac{\text{Desired Dose}}{\text{Available Dose}} \times \text{Quantity}.
125 mcg50 mcg×1 tablet=2.5 tablets\frac{125\text{ mcg}}{50\text{ mcg}} \times 1\text{ tablet} = 2.5\text{ tablets}
This calculation determines the exact physical quantity of the medication to administer based on the available pharmacy supply.

A practical nurse (PN) enters the room of a client who has a T4 spinal cord injury. The client reports a sudden, severe pounding headache and blurred vision. The PN observes profuse diaphoresis above the level of the spinal injury and measures a blood pressure of 210/110 mm Hg. In which order should the PN perform the following actions? (Arrange the actions from first to last)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of actions is to first elevate the head of the bed, followed by inspecting the urinary catheter for blockages, notifying the supervising RN, administering prescribed antihypertensive medication, and finally documenting the event.
Autonomic dysreflexia is a life-threatening hypertensive emergency that occurs in clients with spinal cord injuries at or above the T6 level. The prioritization of care must focus on immediate physiological stabilization. The absolute first action is to elevate the head of the bed to a high-Fowler's position; this immediately helps lower the blood pressure through orthostasis and reduces the risk of cerebral hemorrhage. Next, the nurse must assess for and remove the most common triggering stimulus, which is bladder distention, by checking the catheter for kinks or blockages. If the stimulus cannot be resolved or blood pressure remains high, the nurse must immediately notify the RN to escalate care, followed by administering prescribed PRN antihypertensive medications as directed. Finally, once the crisis is managed and the client is stable, the nurse documents the event, the interventions performed, and the client's response.

Step-by-Step Solution

1
Recognize the clinical presentation of autonomic dysreflexia.
Identify a life-threatening hypertensive emergency.
The client has a T4 injury (above T6), severe hypertension, headache, and diaphoresis, which are hallmark signs of autonomic dysreflexia.
2
Intervene immediately to lower blood pressure physically.
Elevate the head of the bed to 90 degrees.
This decreases venous return and utilizes orthostatic principles to lower blood pressure, reducing the immediate risk of a stroke.
3
Assess for and remove the noxious stimulus.
Inspect the urinary catheter tubing.
A distended bladder from a kinked or obstructed catheter is the most common cause of the massive sympathetic response.
4
Escalate care and provide pharmacological management.
Notify the RN and administer prescribed oral antihypertensives.
Collaboration with the RN is necessary, and medications are indicated if the physical stimulus cannot be immediately resolved.
5
Complete post-event responsibilities.
Document the findings and actions.
Accurate medical records must be maintained after the client is stable and out of immediate danger.

The UAP reports the client has become suddenly agitated, is speaking incoherently, and is trying to remove their intravenous (IV) line. The client was previously alert and oriented. Current vital signs are a heart rate of 112 bpm, blood pressure of 98/62 mm Hg, and a respiratory rate of 26 breaths/min. Which action is the priority for the PN to take?

Show answer & explanation

Answer: Obtain an oxygen saturation reading using a pulse oximeter.

Answer

Obtain an oxygen saturation reading using a pulse oximeter.
Sudden restlessness, agitation, and confusion in an older adult client, especially postoperatively, are cardinal early signs of hypoxia. Combined with borderline tachycardia (112 bpm) and tachypnea (26 breaths/min), the clinical picture strongly suggests an acute respiratory or hemodynamic compromise. According to the ABC (Airway, Breathing, Circulation) prioritization framework, the nurse must first assess the client's oxygenation status before implementing other interventions.

Step-by-Step Solution

1
Analyze the clinical cues in the scenario.
The client is experiencing a sudden onset of agitation, confusion, tachycardia (112 bpm), and tachypnea (26 breaths/min).
Recognizing a sudden change from baseline is critical for identifying acute physiological decompensation.
2
Apply the Airway, Breathing, Circulation (ABC) prioritization framework.
The symptoms strongly suggest a Breathing or oxygenation issue (hypoxia) as the root cause of the acute confusion.
Hypoxia often manifests early as restlessness and altered mental status, especially in older adults.
3
Select the intervention that addresses the highest priority physiological need.
Assessing oxygen saturation provides immediate objective data regarding the client's respiratory status.
Data on oxygenation is required to confirm hypoxia and guide further emergent interventions before addressing secondary issues.

A practical nurse (PN) is reviewing the electronic health record of a client receiving a continuous intravenous heparin infusion for a pulmonary embolism. Which finding poses the greatest physiological risk to the client and requires immediate notification to the registered nurse?

Show answer & explanation

Answer: A platelet count of 85,000/mm³ that has decreased from a baseline of 210,000/mm³.

Answer

The platelet count of 85,000/mm³ that has decreased from a baseline of 210,000/mm³.
A significant decrease in platelets (specifically a drop greater than 50% from baseline or a drop below 150,000/mm³) in a client receiving heparin strongly indicates Heparin-Induced Thrombocytopenia (HIT). This is a severe, immune-mediated complication that causes paradoxical widespread clotting and requires immediate notification of the registered nurse and healthcare provider to stop the infusion and initiate alternative anticoagulation.

Step-by-Step Solution

1
Identify the client's current treatment and its associated severe risks.
The client is on a continuous heparin infusion, which carries a risk of severe bleeding and Heparin-Induced Thrombocytopenia (HIT).
Understanding the specific risks of high-alert medications guides the nurse to look for hallmark complications in the assessment data.
2
Analyze the laboratory data for critical values related to the therapy.
The platelet count has dropped by more than 50% and is critically low, whereas the aPTT of 68 seconds is perfectly therapeutic.
Differentiating between therapeutic effects and adverse reactions is essential for risk reduction.
3
Compare the severity of the physiological findings against environmental or administrative safety issues.
The platelet drop indicates a life-threatening physiological emergency, which takes strict priority over stable vital signs and missing barcode labels.
Clinical prioritization requires addressing immediate, life-threatening physiological complications before system or procedural issues.

The client's admission baseline blood pressure was 128/74 mm Hg. Which action should the nurse prioritize?

Show answer & explanation

Answer: Report the assessment data to the supervising registered nurse.

Answer

The priority is to report the assessment data to the supervising registered nurse to address the potential circulatory compromise.
The correct action is communicating the abnormal vital signs to the supervising registered nurse. Tachycardia combined with a significant drop in blood pressure are classic early signs of shock or internal hemorrhage. Identifying and reporting circulatory instability addresses the 'C' (Circulation) in the ABC prioritization framework and is the most critical safety action.

Step-by-Step Solution

1
Analyze the obtained vital signs against the baseline data.
The heart rate is elevated (116 beats/min) and the blood pressure has dropped significantly (92/54 mm Hg) compared to the baseline (128/74 mm Hg).
Comparing current data to baseline helps identify acute physiological changes.
2
Identify the clinical significance of these vital sign changes.
Tachycardia and hypotension in a postoperative client are classic early indicators of decreased cardiac output, hypovolemia, or internal hemorrhage.
Recognizing signs of shock is essential for preventing rapid deterioration.
3
Determine the priority intervention within the practical nursing scope of practice.
The supervising RN must be informed immediately to facilitate rapid assessment and medical intervention.

An unconscious client requires morning oral hygiene. To prevent aspiration and ensure safety, in what order should the practical nurse complete the following steps? Arrange the actions in the correct chronological sequence.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for providing oral care to an unconscious client begins with lateral positioning to prevent aspiration, followed by placing protective linens, safely opening the mouth with a padded blade, performing the cleaning, and finally suctioning excess fluids.
When providing oral care to an unconscious client, the absolute priority is preventing aspiration. Therefore, positioning the client laterally (side-lying) is the crucial first step. Once the airway is protected by gravity, the nurse protects the linens, safely opens the mouth using a padded instrument, cleans the oral cavity, and finally suctions the remaining fluids to ensure the mouth is clear and safe.

Step-by-Step Solution

1
Position the client in a side-lying (lateral) posture with the head turned to the side.
The airway is protected from introduced fluids.
This utilizes gravity to allow fluids to drain out of the mouth, significantly reducing the risk of pulmonary aspiration.
2
Place a waterproof pad and towel under the client's chin with an emesis basin nearby.
The client's gown and bed linens remain dry and clean.
Preparing the immediate area provides a receptacle for the draining fluids and maintains hygiene.
3
Carefully separate the client's upper and lower teeth using a padded tongue blade.
The oral cavity becomes accessible for the cleaning procedure.
Unconscious clients may exhibit a bite reflex; a padded blade protects both the client's dentition and the nurse's fingers.
4
Clean the teeth, gums, and oral mucosa using a moistened soft toothbrush.
Plaque, bacteria, and crusts are removed from the oral cavity.
Routine cleaning maintains oral tissue integrity and reduces the bacterial load that can cause aspiration pneumonia.
5
Use a Yankauer suction catheter to remove excess oral secretions and rinse fluid.
The oral cavity is left clean and free of pooled liquids.
Immediate removal of residual fluids ensures the airway remains unobstructed after the hygiene procedure is complete.

During a shift assessment on an orthopedic unit, a practical nurse evaluates a client with a newly applied plaster cast on the lower left leg. The client describes an intense, throbbing pain that has worsened significantly despite receiving a scheduled intravenous analgesic one hour ago. The nurse observes that the client's toes are cool to the touch and the pedal pulse is weak. While the charge nurse is notifying the healthcare provider of these findings, which action should the practical nurse implement?

Show answer & explanation

Answer: Keep the affected extremity resting flat on the bed at the level of the client's heart

Answer

The nurse should keep the affected extremity resting flat on the bed at the level of the client's heart.
When compartment syndrome is suspected, the affected extremity must be maintained at the level of the heart. Elevating the limb above the heart decreases arterial pressure and further compromises tissue perfusion to the ischemic area. Lowering it below the heart increases venous congestion. Keeping it flat at heart level optimizes the balance of blood flow.

Step-by-Step Solution

1
Analyze the client's clinical presentation.
The intense pain unrelieved by medication, cool toes, and weak pedal pulse are classic signs of compromised circulation, specifically compartment syndrome.
Recognizing these signs is essential to determine that routine cast care is no longer appropriate.
2
Determine the physiological effect of positioning on a limb with compartment syndrome.
Elevating the limb decreases arterial blood flow, while lowering it increases venous pooling.
Improper positioning can cause irreversible tissue damage by starving the ischemic tissues of remaining arterial flow.
3
Select the intervention that prioritizes circulation and prevents further harm.
Placing the affected leg flat on the bed at heart level is the safest immediate action.
This supports optimal arterial perfusion without exacerbating venous congestion while awaiting emergency medical intervention.

Next, find the total daily dose: 17 kg×14 mg/kg/day=238 mg/day17\text{ kg} \times 14\text{ mg/kg/day} = 238\text{ mg/day}. Because it is given every 12 hours, divide by 2: 238÷2=119 mg/dose238 \div 2 = 119\text{ mg/dose}. Using the concentration of 250 mg250\text{ mg} in 5 mL5\text{ mL}, calculate the volume: (119 mg÷250 mg)×5 mL=2.38 mL(119\text{ mg} \div 250\text{ mg}) \times 5\text{ mL} = 2.38\text{ mL}. Finally, round to the nearest tenth to get 2.42.4.

Step-by-Step Solution

1
Convert the client's weight from pounds to kilograms.
37.4 lb÷2.2 lb/kg=17 kg37.4\text{ lb} \div 2.2\text{ lb/kg} = 17\text{ kg}
Weight-based pediatric dosages require the weight to be in kilograms.
2
Calculate the total daily medication dosage.
17 kg×14 mg/kg/day=238 mg/day17\text{ kg} \times 14\text{ mg/kg/day} = 238\text{ mg/day}
The prescription is written as a daily total based on the child's weight.
3
Calculate the single dose amount.
238 mg/day÷2 doses/day=119 mg/dose238\text{ mg/day} \div 2\text{ doses/day} = 119\text{ mg/dose}
The medication is ordered every 12 hours, meaning the total daily amount must be divided into 2 equal doses.
4
Calculate the volume to administer for one dose using the final concentration.
119 mg250 mg×5 mL=2.38 mL\frac{119\text{ mg}}{250\text{ mg}} \times 5\text{ mL} = 2.38\text{ mL}
The concentration is 250 mg250\text{ mg} per 5 mL5\text{ mL}. The reconstitution water volume (38 mL38\text{ mL}) and total yield (60 mL60\text{ mL}) are distractors and not used in the formula.
5
Round the calculated volume to the nearest tenth as instructed.
2.382.38 rounds to 2.42.4
Standard rounding rules state that if the hundredths digit is 5 or greater, round up the tenths digit.

A practical nurse is assisting with the preparation of a client with severe hepatic cirrhosis who is scheduled for a bedside paracentesis. In what order should the nurse perform the following actions to minimize the risk of procedural complications, such as bladder perforation?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence prioritizes administrative safety (verifying consent), followed by physiological risk reduction (emptying the bladder), obtaining accurate baseline data, optimal client positioning, and finally, establishing the sterile field.
Preparing for a paracentesis requires a strategic sequence to ensure client safety. Consent must be verified first. The client must then empty their bladder to drastically reduce the risk of a bladder perforation when the needle is inserted. Baseline vitals, weight, and abdominal girth must be measured immediately after voiding for accuracy. The client is then placed upright so gravity pools the ascites in the lower abdomen, safely away from vital organs. Finally, the sterile field is established.

Step-by-Step Solution

1
Verify informed consent.
Legal and administrative safety is established.
No preparatory actions should begin until the client has officially consented to the procedure.
2
Have the client empty their bladder.
The bladder is decompressed and moves safely down into the pelvis.
A full bladder extends upward into the abdominal cavity, greatly increasing the risk of accidental puncture by the paracentesis needle.
3
Obtain baseline vital signs, weight, and abdominal girth.
Accurate physiological baseline data is recorded.
Measurements must be taken after the bladder is emptied so that the weight and girth solely reflect the body mass and ascitic fluid, ensuring accurate post-procedure evaluation.
4
Position the client upright (high Fowler's or sitting).
The ascitic fluid pools in the lower abdominal cavity.
Gravity forces the fluid downward, making it easier to drain and naturally shifting the intestines away from the planned puncture site.
5
Prepare the sterile tray and equipment.
The sterile field is ready for the provider.
Supplies should be opened and prepared immediately before the procedure begins to reduce the risk of environmental contamination.

Question 518Question →

An older adult client is recovering on the medical-surgical unit 90 minutes after an image-guided percutaneous liver biopsy. The client is currently positioned on the right side with a rolled towel under the lower ribs. During a routine check, the client's blood pressure is 108/68 mm Hg, heart rate is 92 beats/minute, and they report a sudden onset of mild but persistent right shoulder pain. What is the priority action for the practical nurse to take?

Show answer & explanation

Answer: Inform the supervising registered nurse immediately about the client's reported symptoms.

Answer

Inform the supervising registered nurse immediately about the client's reported symptoms.
Right shoulder pain following a percutaneous liver biopsy is a classic presentation of referred pain caused by diaphragmatic irritation from a subcapsular hematoma or bile leak. Coupled with a heart rate of 92 beats/minute, this indicates a high likelihood of active internal bleeding. The practical nurse must prioritize client safety by immediately escalating these findings to the registered nurse for advanced assessment and rapid intervention.

Step-by-Step Solution

1
Analyze the client's post-procedure requirements.
The client had a highly vascular procedure (liver biopsy) and is at high risk for hemorrhage.
Understanding the specific risks of the procedure establishes the baseline for evaluating new data.
2
Evaluate the clinical data and the client's new symptom.
The client has slight tachycardia (92 bpm) and new right shoulder pain.
Vital signs and pain characteristics must be correlated with potential complications.
3
Correlate the shoulder pain with anatomical pathology.
Right shoulder pain is recognized as referred pain from the phrenic nerve due to blood or bile irritating the diaphragm.
Distinguishing expected discomfort from pathological referred pain is crucial for clinical judgment.
4
Determine the appropriate practical nursing action.
Escalate the finding immediately to the registered nurse.
A potential hemorrhage is unstable and requires comprehensive RN assessment and provider notification, which exceeds independent PN scope.

A practical nurse is assessing a client who is 24 hours24\text{ hours} post-operative following a right total knee arthroplasty. Which of the following findings should the practical nurse identify as potential complications requiring immediate notification of the registered nurse? Select all that apply.

Select all that apply

Show answer & explanation

Answer: The client's right calf is swollen, red, and warm to the touch.; The client reports a sudden onset of shortness of breath and an oxygen saturation of 88%88\% on room air.; The client's most recent serum hemoglobin level is 7.1 g/dL7.1\text{ g/dL}.

Answer

The findings that require immediate notification of the registered nurse are the swollen, red, and warm right calf; the sudden onset of shortness of breath with an oxygen saturation of 88%; and the critically low serum hemoglobin level of 7.1 g/dL.
The correct choices represent severe, life-threatening post-operative complications. A swollen, red, and warm calf suggests a deep vein thrombosis (DVT). Sudden shortness of breath and hypoxia suggest a pulmonary embolism (PE). A hemoglobin level of 7.1 g/dL is a critical laboratory value indicating severe anemia or potential hemorrhage. All of these require immediate escalation to the registered nurse for prompt medical intervention.

Step-by-Step Solution

1
Evaluate each assessment finding to determine if it is an expected post-operative finding or a potential complication.
The calf symptoms, sudden shortness of breath, and low hemoglobin are identified as abnormal and potentially life-threatening.
Clients recovering from total joint arthroplasties carry a high risk for venous thromboembolism (DVT and PE) and significant blood loss.
2
Determine the appropriate scope of practice for the practical nurse regarding the identified abnormal findings.
The practical nurse must immediately escalate these critical findings to the registered nurse for further assessment and provider notification.
The registered nurse is responsible for the overall nursing care plan, complex assessments, and coordinating emergency medical interventions.

Question 520Question →

A practical nurse is assisting with the admission of a client who has just returned to the nursing unit after a percutaneous liver biopsy. Which of the following positions is most appropriate for the nurse to place the client in to prevent post-procedure complications?

Show answer & explanation

Answer: Right side-lying with a rolled towel placed directly under the puncture site

Answer

Right side-lying with a rolled towel placed directly under the puncture site
The correct position is right side-lying with a rolled towel under the puncture site because the liver is located on the right side of the body. Using the client's body weight to press against a towel provides continuous, direct pressure to the biopsy site, which is highly vascular, thereby minimizing the risk of hemorrhage.

Step-by-Step Solution

1
Identify the procedure performed and the primary associated risk.
The client had a percutaneous liver biopsy, which carries a high risk of internal bleeding due to the liver's high vascularity.
Understanding the procedure's complications is essential for determining the correct preventative nursing intervention.
2
Determine the anatomical location of the liver and the mechanism needed to stop bleeding.
The liver is located on the right side of the abdomen. Applying direct, localized pressure is required to promote hemostasis.
Matching the anatomical site with the physiological need for pressure guides the choice of positioning.
3
Select the client position that best achieves this clinical objective.
Positioning the client on their right side with a towel or pillow under the puncture site uses the client's own body weight to apply pressure.
This specific physical alignment is the standard of care for preventing hemorrhage following a liver biopsy.
