A practical nurse is caring for a client who is 12 hours postoperative following a total thyroidectomy. The client reports neck discomfort and requests assistance with repositioning. Which action is most appropriate for the nurse to take?

Cevabı ve açıklamayı göster

Cevap: Maintain the client in a semi-Fowler's position and support the head and neck.

Cevap

The nurse should maintain the client in a semi-Fowler's position and support the head and neck.
The correct action demonstrates appropriate postoperative positioning for comfort and safety. Elevating the head of the bed to a semi-Fowler's position decreases swelling and promotes optimal lung expansion. Supporting the head and neck with pillows or sandbags maintains a neutral alignment, avoiding tension or pulling on the surgical sutures.

Adım Adım Çözüm

1
Identify the surgical procedure and its specific risks.
The client had a total thyroidectomy, which carries high risks for airway compromise, neck edema, and strain on the suture line.
Understanding the anatomical risks dictates safe basic care and comfort measures.
2
Determine the optimal positioning for this specific postoperative client.
The semi-Fowler's position (head of bed elevated 30-45 degrees) with careful neck support in a neutral position is required.
Elevation reduces swelling and facilitates respiratory effort, while support prevents hyperextension of the neck.
3
Evaluate the remaining options for safety violations.
Flat positioning worsens edema; delegating to assistive personnel is unsafe due to the need for strict alignment; and giving fluids ignores airway safety protocols.
Distractors represent common procedural and prioritization errors in postoperative basic care.

Cevap: Place a small, rolled towel under the lumbar region of the client's back.; Use a low-profile fracture pan for elimination to minimize pelvic and leg movement.; Offer oral fluids frequently by keeping a water pitcher within the client's reach.

Cevap

The correct actions are to place a rolled towel under the lumbar region, use a low-profile fracture pan for elimination, and offer oral fluids frequently.
After a femoral cardiac catheterization, the affected leg must remain straight and the head of the bed elevated no more than 30 degrees to prevent hemorrhage. Placing a small rolled towel under the lumbar region effectively relieves lower back ache without compromising this required positioning. Using a low-profile fracture pan allows for safe elimination while keeping the right leg straight and minimizing pelvic movement. Encouraging oral fluids is a vital basic care measure to excrete the contrast medium used during the procedure and maintain hydration.

Adım Adım Çözüm

1
Identify the critical safety constraints for a post-femoral cardiac catheterization client.
The client must remain on strict bed rest with the affected (right) leg completely straight, and the head of the bed must not be elevated more than 30 degrees to prevent arterial bleeding.
Maintaining hemostasis at the femoral puncture site is the highest priority.
2
Evaluate the comfort and elimination options against the positioning constraints.
Providing a small lumbar roll and using a fracture pan allow the nurse to manage the client's back pain and elimination needs without flexing the hip or lifting the pelvis excessively.
Basic care must be adapted to fit strict procedural precautions.
3
Assess the remaining basic care interventions for safety and efficacy.
Offering oral fluids is safe and necessary to excrete contrast dye. Conversely, flexing the right knee, elevating the head to 45 degrees, or applying heat to the groin directly contradict safety protocols and risk hemorrhage.
Interventions that increase intra-abdominal pressure, bend the hip/knee, or cause vasodilation must be avoided.

Cevabı ve açıklamayı göster

Cevap: Inspect the client's stools and emesis for the presence of frank red blood or a coffee-ground appearance.; Verify the client's identity using two unique identifiers before administering any prescribed medications.; Monitor the client's intravenous (IV) access site frequently for signs of infiltration, phlebitis, or bleeding.

Cevap

The correct actions are to inspect stools and emesis for blood, verify the client's identity before medication administration, and monitor the IV site frequently.
To effectively reduce the risk of complications, the practical nurse must prioritize fundamental safety protocols and vigilant clinical monitoring. Verifying client identity prevents medication errors. Inspecting stools and emesis for blood allows for the early detection of recurrent hemorrhage. Finally, frequent monitoring of the IV site ensures that emergency fluids or blood products can be administered rapidly and safely if the client's condition suddenly deteriorates.

Adım Adım Çözüm

1
Analyze the client's clinical situation and current risks.
The client is recovering from a gastrointestinal bleed and is receiving IV fluids, placing them at risk for recurrent hemorrhage, hypovolemic shock, localized IV complications, and medication errors.
Understanding the primary physiological and environmental risks allows the nurse to prioritize interventions that actively prevent complications.
2
Evaluate each nursing action for safety, effectiveness, and appropriate scope of practice.
Monitoring for bleeding, verifying identity, and checking IV patency are safe, appropriate actions within the practical nurse scope that actively reduce client risk.
These actions directly address the risk of medication errors, identify recurrent bleeding early, and ensure a safe route for emergency interventions.
3
Identify inappropriate or unsafe actions that increase client risk.
Delaying the report of a critically low hemoglobin level, ignoring early signs of shock, and delegating nursing assessments to UAP are unsafe actions.
These inappropriate actions violate safety protocols, delay life-saving medical interventions, and fall outside the legal scope of practice for delegation.

Cevap

The correct sequence is to verify the blood glucose first, immediately treat with a fast-acting carbohydrate, recheck the glucose in 15 minutes to evaluate effectiveness, and finally provide a sustaining snack once stable.
The standard management for acute hypoglycemia in a conscious client follows the 'rule of 15'. The nurse must first collect data by checking the blood glucose to confirm the condition. Next, the nurse administers 15 grams of a fast-acting carbohydrate (such as juice) to rapidly correct the low blood sugar. The nurse then waits 15 minutes and reassesses the blood glucose to ensure the intervention was effective. Finally, once the blood glucose is in a safe range, providing a snack with complex carbohydrates and protein helps sustain the blood glucose level and prevents it from dropping again.

Cevabı ve açıklamayı göster

Cevap: Elevate the right leg by placing a pillow under the lower calf and ankle, keeping the knee straight.

Cevap

Elevate the operative leg by placing a pillow under the lower calf and ankle, ensuring the knee itself remains unsupported and fully extended.
Following a total knee arthroplasty, it is critical to maintain the operative knee in full extension during periods of rest to prevent a flexion contracture. Elevating the leg by placing a pillow under the lower calf and ankle allows for venous return and reduction of postoperative edema while ensuring the knee joint remains straight, properly aligned, and unsupported.

Adım Adım Çözüm

1
Evaluate the client's request for a pillow directly under the operative knee.
Recognize that fulfilling this request would place the knee in a flexed position.
Knee flexion must be avoided during rest periods after a total knee arthroplasty to prevent the development of a flexion contracture.
2
Determine the optimal positioning intervention that addresses both discomfort and postoperative swelling.
Select a positioning strategy that elevates the limb without bending the joint.

Select all that apply.

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Apical pulse of 114 beats/min with a narrow pulse pressure; Restlessness and continuous picking at the bed linens; Total urine output of 45 mL documented over the previous 3 hours

Cevap

The findings that indicate systemic decompensation are the elevated apical pulse with narrow pulse pressure, restlessness with picking at linens, and oliguria (45 mL over 3 hours).
In an older adult postoperative client, early signs of systemic decompensation (such as hypovolemic or septic shock) are often subtle. Tachycardia combined with a narrow pulse pressure indicates an early compensatory mechanism to maintain cardiac output. Restlessness and altered behavior are frequently the first indicators of cerebral hypoxia or poor tissue perfusion. Furthermore, a urine output of 45 mL over 3 hours averages to 15 mL/hr, which falls significantly below the minimum expected threshold of 30 mL/hr, demonstrating inadequate renal perfusion. These findings point directly to an ABC (Circulation) emergency requiring immediate escalation.

Adım Adım Çözüm

1
Analyze the client's postoperative timeline and expected baseline.
The client is 3 days post-colectomy; moderate pain during movement, hypoactive bowel sounds, and minimal serosanguineous drainage are expected findings.
To accurately differentiate between normal recovery trajectory and acute complications.
2
Evaluate the objective cardiovascular and renal data for signs of impaired perfusion.
Tachycardia (114 beats/min), a narrow pulse pressure, and severe oliguria (15 mL/hr) are identified.
These specific signs indicate sympathetic nervous system activation and decreased organ perfusion, classic hallmarks of early shock.
3
Assess the neurological finding of restlessness in the context of the client's age.
The restlessness and picking at linens are recognized as acute delirium secondary to physiological stress or hypoxia, not a normal aging change.
Altered mental status is frequently the very first sign of physiological deterioration in the older adult population.

Cevap: Elevate the head of the bed to a high Fowler's position and measure the oxygen saturation level

Cevap

Elevate the head of the bed to a high Fowler's position and measure the oxygen saturation level
The correct answer addresses the client's Airway, Breathing, and Circulation (ABC) priorities. Sudden agitation, restlessness, a feeling of impending doom, tachypnea, and tachycardia in a bedbound client are classic early signs of hypoxia, potentially from a pulmonary embolism. The nurse must prioritize respiratory support by immediately elevating the head of the bed to maximize lung expansion and collecting oxygenation data before notifying the registered nurse.

Adım Adım Çözüm

1
Analyze the client's clinical presentation.
The client has sudden onset agitation, a feeling of impending doom, tachypnea (respiratory rate of 24), and tachycardia (heart rate of 112) while on prolonged bed rest.
Identifying the cluster of symptoms helps differentiate between psychological/behavioral issues and physiological deterioration.
2
Determine the most life-threatening potential complication.
The combination of immobility and sudden respiratory distress strongly suggests a pulmonary embolism or acute hypoxia.
Sudden confusion or agitation in older adults should always be treated as hypoxia or an acute physiological event until proven otherwise.
3
Apply the ABC (Airway, Breathing, Circulation) prioritization framework.
Interventions that support Breathing (positioning) and assess oxygenation (pulse oximetry) take immediate precedence over comfort or behavioral measures.
Maximizing lung expansion and identifying the severity of hypoxia are the most critical immediate actions within the practical nurse scope of practice.

Which of the following is the priority action for the PN?

Cevabı ve açıklamayı göster

Cevap: Notify the registered nurse (RN) immediately

Cevap

Notify the registered nurse (RN) immediately.
The correct answer addresses a critical, life-threatening complication. Following a cardiac catheterization via the femoral artery, blood can leak from the puncture site into the retroperitoneal space. Because this space can hold a large volume of blood before outward signs appear, the classic presentation is new-onset back or flank pain combined with subtle signs of hypovolemic shock, such as tachycardia (heart rate of 108) and dropping blood pressure. The PN must recognize these signs as an emergency and immediately notify the RN to facilitate rapid interventions like IV fluid resuscitation and a CT scan.

Adım Adım Çözüm

1
Analyze the client's new symptoms and vital signs in the context of the recent invasive procedure.
The client has new lower back pain, tachycardia (HR 108), and a borderline low blood pressure (100/62) following a right femoral artery puncture.
Recognizing patterns of complications after specific procedures is essential for early identification of life-threatening events.
2
Correlate the findings with potential post-procedure complications.
Bleeding from a femoral arterial puncture can track backward into the retroperitoneal space, causing flank or lower back pain and systemic signs of hypovolemia.
Retroperitoneal hemorrhage is a known, severe complication of femoral cardiac catheterization.
3
Determine the priority nursing action within the PN scope of practice.
The priority is to immediately notify the RN or healthcare provider to initiate rapid medical intervention.
Internal hemorrhage leading to shock requires urgent collaborative management beyond the scope of independent PN practice.

Cevap: Apply supplemental oxygen, verify the patency of the intravenous infusion, and urgently notify the registered nurse.

Cevap

The correct answer is to apply supplemental oxygen, verify the patency of the intravenous infusion, and urgently notify the registered nurse.
The client's clinical presentation—sudden agitation, clammy and pale skin, tachycardia, tachypnea, and hypotension—strongly indicates the onset of hypovolemic or hemorrhagic shock. The acute confusion is a direct result of decreased cerebral perfusion. In this emergent situation, the nurse must prioritize Airway, Breathing, and Circulation (ABCs). Applying supplemental oxygen addresses the immediate tissue hypoxia, verifying intravenous patency ensures the route is available for fluid resuscitation, and notifying the registered nurse facilitates the necessary medical interventions and escalated level of care.

Adım Adım Çözüm

1
Analyze the clinical data and vital signs.
The client is displaying tachycardia, hypotension, tachypnea, clammy skin, and sudden altered mental status.
Identifying clustered deviations from normal is the first step in clinical judgment.
2
Synthesize the findings to determine the underlying physiological issue.
The combination of these signs points directly to hypovolemic or hemorrhagic shock, which compromises cerebral perfusion and causes agitation.
Recognizing patterns of acute deterioration ensures that the root cause, rather than just the surface symptoms, is addressed.
3
Prioritize nursing action based on ABCs and the PN scope of practice.
Immediate interventions must support oxygenation and circulation, followed by rapid escalation to the RN.
The practical nurse must stabilize the client's basic physiological needs and immediately report life-threatening conditions for collaborative management.

Cevap

The correct sequence of actions is to first call for help while staying with the client, position the client to reduce abdominal tension, cover the exposed organs with moist sterile dressings, assess vital signs for shock, and maintain NPO status for emergency surgery.
In an acute evisceration, the practical nurse must prioritize actions that protect the client and the exposed organs while expediting emergency medical intervention. First, the nurse must never leave the client; activating the emergency system brings necessary personnel and sterile supplies to the bedside. Next, positioning the client in a low-Fowler's position with flexed knees is a critical mechanical intervention that instantly reduces intra-abdominal pressure and prevents further protrusion of the bowel. Once sterile supplies are available, the nurse must cover the exposed viscera with sterile, saline-moistened dressings to prevent tissue necrosis and severe infection. After the site is physically protected, obtaining vital signs is essential to monitor for hypovolemic shock, a major systemic complication of evisceration. Finally, because evisceration requires immediate operative repair, the nurse must ensure the client is kept strictly NPO to prevent aspiration during anesthesia.

Adım Adım Çözüm

1
Activate the emergency response while staying with the client.
Ensures the client remains safe while necessary sterile supplies and personnel are brought to the bedside.
The practical nurse must not leave an unstable client; leaving could lead to further injury or severe complications.
2
Place the client in a low-Fowler's position with knees flexed.
Minimizes intra-abdominal pressure.
Relieving tension on the abdominal wall physically prevents further evisceration of internal organs.
3
Apply sterile, saline-moistened dressings over the evisceration.
Protects the exposed bowel from the external environment.
Exposed viscera are highly susceptible to drying and infection, which can cause tissue necrosis. Sterile normal saline maintains moisture safely.
4
Assess and document the client's vital signs.
Provides baseline hemodynamic data.
Evisceration can trigger a massive stress response and fluid shifts, leading to hypovolemic shock. Tachycardia and hypotension require immediate medical intervention.

The correct priority sequence for a suspected hemolytic transfusion reaction is to first stop the transfusion, secure the IV line with normal saline using new tubing, notify the supervising RN, assess vital signs, and finally send the blood product to the blood bank.
In the event of a blood transfusion reaction, the immediate priority is to stop the cause of the reaction (following Airway, Breathing, Circulation principles by stopping the harmful agent first). Next, IV access must be maintained for potential emergency drug administration, which requires entirely new tubing primed with normal saline. Following this, the PN must notify the RN to escalate the emergency. Assessing vital signs is the next priority to monitor for shock and respiratory distress. Finally, administrative and diagnostic steps, such as returning the blood to the lab, are completed.

Adım Adım Çözüm

1
Stop the blood transfusion immediately.
The infusion of the potentially incompatible blood product is halted.
This is the most critical first step to minimize the volume of reactive blood entering the client's circulation.
2
Connect new tubing primed with 0.9% normal saline.
Intravenous access is maintained without infusing residual blood.
Emergency medications may be needed, so the IV site must be kept open, but flushing the old tubing would worsen the reaction.
3
Notify the supervising RN.
The healthcare team is alerted to the medical emergency.
The RN will contact the healthcare provider for emergency orders and assist with advanced assessments.
4
Assess vital signs and respiratory status.
Objective data regarding the client's hemodynamic stability is collected.
Vital signs help determine the severity of the reaction and guide further therapeutic interventions.
5
Return the blood bag and tubing to the blood bank.

Cevap: A client taking warfarin for atrial fibrillation who has an International Normalized Ratio (INR) of 5.2

Cevap

The client taking warfarin who has an International Normalized Ratio (INR) of 5.2.
An International Normalized Ratio (INR) of 5.2 is critically elevated beyond the standard therapeutic target of 2.0 to 3.0 for a client with atrial fibrillation. This places the client at imminent risk for spontaneous, severe hemorrhage. The practical nurse must immediately report this finding to the registered nurse so that anticoagulant medications can be withheld and the provider can determine if an antidote or dosage adjustment is necessary.

Adım Adım Çözüm

1
Analyze each client situation to distinguish between routine nursing tasks, independent safety interventions, and critical physiological threats.
The analgesic request and consent signature are routine tasks. The missing ID band is a safety issue the nurse can fix independently. The INR of 5.2 is a critical laboratory abnormality.
Prioritization requires identifying which situation poses the most immediate risk of harm that exceeds the practical nurse's independent scope of practice.
2
Evaluate the clinical significance of an International Normalized Ratio (INR) of 5.2.
An INR of 5.2 is dangerously high and greatly exceeds the standard therapeutic range of 2.0 to 3.0 for a client with atrial fibrillation.
Elevated coagulation times indicate that the client's blood is clotting too slowly, creating a severe risk for internal or spontaneous bleeding.
3
Determine the appropriate nursing action for the critical finding.
The practical nurse must immediately communicate this critical laboratory value to the registered nurse.
The registered nurse must collaborate with the healthcare provider to potentially hold medications, administer antidotes, or order further diagnostic testing.

Cevap

The correct actions are withholding the lisinopril and notifying the RN, reinforcing bleeding precautions, and administering the enoxaparin into the anterolateral abdominal wall.
The practical nurse demonstrates safe care by withholding the antihypertensive medication in the presence of significant hypotension and escalating the abnormal vital signs to the RN. Furthermore, reinforcing previously taught information about bleeding risks associated with anticoagulants and utilizing the correct anatomical site (abdomen) for subcutaneous enoxaparin are safe, standard practices within the practical nursing scope.

Adım Adım Çözüm

1
Analyze the client's vital signs in relation to the prescribed medications.
The client is hypotensive (88/54 mm Hg) and tachycardic (118 beats/min). Lisinopril is contraindicated at this time.
Administering an antihypertensive to a hypotensive client compromises safety and perfusion.
2
Evaluate the remaining tasks against the PN scope of practice.
Reinforcing teaching and administering subcutaneous injections are within the PN scope. Titrating IV infusions is out of scope.
The PN must only perform tasks that are legally and clinically within their designated role.
3
Review standard medication administration procedures.
Two client identifiers must always be checked, and abnormal vital signs must be reported, not ignored.

Cevap: Withhold the scheduled dose of oral lisinopril.; Notify the registered nurse (RN) regarding the client's laboratory results.; Administer the oral sevelamer while the client is eating their morning meal.

Cevap

The correct actions are to withhold the oral lisinopril, notify the registered nurse (RN) of the laboratory results, and administer the oral sevelamer with the client's meal.
In a client with end-stage renal disease, managing medications around critical laboratory values is essential. Lisinopril (an ACE inhibitor) must be withheld because it can exacerbate the client's hyperkalemia (potassium 5.8 mEq/L). The phosphate binder sevelamer must be administered directly with meals to effectively bind to dietary phosphorus and lower the elevated serum phosphorus (6.5 mg/dL). Finally, the PN must strictly operate within their scope of practice by notifying the RN of these critical laboratory values and the withheld medications to ensure collaborative management.

Adım Adım Çözüm

1
Analyze the client's morning laboratory results against normal reference ranges.
The potassium (5.8 mEq/L) is high, hemoglobin (11.5 g/dL) is above the target range for epoetin therapy, and phosphorus (6.5 mg/dL) is high.
Recognizing critical laboratory values is the first step in ensuring safe medication administration.
2
Evaluate the scheduled medications in relation to the abnormal laboratory findings.
Lisinopril worsens hyperkalemia, epoetin alfa is contraindicated with hemoglobin > 11.0 g/dL, and sevelamer treats hyperphosphatemia when given with food.
Medications must be correlated with current data to determine if they should be administered or withheld.
3
Determine the appropriate interventions within the practical nurse scope of practice.
The PN must withhold the unsafe medications (lisinopril, epoetin alfa), administer the safe medication correctly (sevelamer with meals), and escalate the findings to the RN.
The PN is responsible for safe medication administration and timely reporting of significant changes.

During morning rounds, a practical nurse (PN) evaluates an octogenarian client who has a known history of gastric ulcers. The client's baseline mental status is alert and oriented; however, the client is now displaying acute confusion and restlessness along with vague complaints of a stomach ache. The client's current heart rate is 114 beats/minute with a blood pressure of 102/64 mm Hg, representing a drop from a baseline blood pressure of 144/82 mm Hg. Which action should the PN take first?

Cevap: Report the assessment findings and change in mental status to the supervising registered nurse immediately.

Cevap

Report the assessment findings and change in mental status to the supervising registered nurse immediately.
The correct action involves immediately escalating the client's condition to the registered nurse. The combination of acute confusion, restlessness, tachycardia, and a significant drop in baseline blood pressure in a client with a history of gastric ulcers strongly indicates early hemorrhagic shock from a gastrointestinal bleed. The practical nurse must recognize this acute physiological deterioration and immediately notify the registered nurse so that advanced assessment, provider notification, and life-saving fluid resuscitation can be initiated.

Adım Adım Çözüm

1
Analyze the client's vital signs and clinical presentation.
The client has unexplained tachycardia, relative hypotension compared to baseline, acute confusion, and restlessness.
Identifying abnormal data and comparing it to the client's baseline is the first step in the clinical judgment process.
2
Correlate the assessment findings with the client's medical history.
The history of gastric ulcers combined with signs of decreased systemic perfusion strongly suggests active gastrointestinal bleeding.
Connecting the client's past medical history with acute symptoms helps identify the likely underlying complication.
3
Determine the priority nursing action based on the practical nurse (PN) scope of practice.
The PN must immediately escalate the unstable client's condition to the registered nurse for advanced intervention.
The client is experiencing a life-threatening emergency (hypovolemic shock) that requires immediate RN assessment and provider notification for fluid resuscitation.

Cevap: Heart rate of 114 beats per minute with weak peripheral pulses; Sudden onset of agitation and attempting to pull at the surgical dressing; Blood pressure of 102/68 mm Hg, down from a preoperative baseline of 138/82 mm Hg; Urine output of 35 mL collected in the drainage bag over the past two hours

Cevap

The correct indicators of hypovolemic shock are a rapid heart rate with weak pulses, sudden agitation, a significant drop in baseline blood pressure, and abnormally low urine output.
Hypovolemic shock occurs when there is a significant loss of blood or fluids, which is a major risk following abdominal surgery. Early signs manifest as the body attempts to compensate for decreased perfusion. A rapid heart rate (tachycardia) and weak pulses occur because the heart must pump faster to circulate the reduced volume. A significant drop in blood pressure from the client's baseline indicates that these compensatory mechanisms are failing. Decreased urine output (averaging 17.5 mL/hr in this scenario, which is below the 30 mL/hr minimum) occurs because blood is shunted away from the kidneys to protect vital organs. Sudden agitation or restlessness is frequently the earliest sign of shock due to a reduction in oxygen delivery to the brain.

Adım Adım Çözüm

1
Analyze the clinical scenario and the client's risk profile.
The client is an older adult, 12 hours post-abdominal surgery, placing them at high risk for hemorrhage and fluid shifts leading to hypovolemia.
Identifying the primary complication risk provides context for evaluating which symptoms are life-threatening.
2
Evaluate the cardiovascular and renal data for signs of decreased perfusion.
Tachycardia (114 bpm), relative hypotension (drop from 138/82 to 102/68), and oliguria (35 mL over 2 hours) all strongly indicate a loss of circulatory volume.
The body compensates for low blood volume by increasing heart rate and shunting blood away from the kidneys, reducing urine output.
3
Assess neurological findings in the context of physiological adaptation.
The new onset of agitation is a classic early sign of cerebral hypoxia.
The brain is highly sensitive to reduced oxygen delivery, making acute behavioral changes a priority assessment.
4
Differentiate critical indicators from expected postoperative findings.
Incisional pain with movement and a mild temperature elevation (99.2°F) are identified as expected normal responses to tissue trauma.
Safe nursing care requires prioritizing ABCs (Airway, Breathing, Circulation) over expected secondary discomforts.

Cevap: 10.5

Cevap

The practical nurse should administer 10.5 mL.
The correct volume is 10.5 mL10.5 \text{ mL}. To find this, the nurse must first convert the weight from pounds to kilograms (154÷2.2=70 kg154 \div 2.2 = 70 \text{ kg}). Next, determine the ordered dose by multiplying the weight by the prescription (70 kg×7.5 mg/kg=525 mg70 \text{ kg} \times 7.5 \text{ mg/kg} = 525 \text{ mg}). Finally, calculate the volume using the ratio of the available medication: (525 mg÷250 mg)×5 mL=10.5 mL(525 \text{ mg} \div 250 \text{ mg}) \times 5 \text{ mL} = 10.5 \text{ mL}.

Adım Adım Çözüm

1
Convert the client's weight from pounds to kilograms.
154 lb÷2.2 lb/kg=70 kg154 \text{ lb} \div 2.2 \text{ lb/kg} = 70 \text{ kg}
The prescribed medication is dosed based on the client's weight in kilograms.
2
Calculate the total required dose in milligrams.
70 kg×7.5 mg/kg=525 mg70 \text{ kg} \times 7.5 \text{ mg/kg} = 525 \text{ mg}
This determines the exact amount of medication the client needs per dose based on the order.
3
Calculate the volume of liquid to administer in milliliters.
(525 mg250 mg)×5 mL=10.5 mL(\frac{525 \text{ mg}}{250 \text{ mg}}) \times 5 \text{ mL} = 10.5 \text{ mL}
This determines how much of the supplied concentration is needed to deliver the required dose.
