Current vital signs are: blood pressure 92/58 mm Hg, apical pulse 116 beats/min, and respirations 22 breaths/min. The client's urine output for the last 4 hours was 85 mL. Which action should the practical nurse take first?

Withhold the metoprolol and immediately report the assessment findings to the registered nurse.

Administer the scheduled metoprolol because the client's heart rate is elevated.

Initiate a prescribed as-needed rapid intravenous fluid bolus of normal saline.

Delay the metoprolol and prioritize administering a prescribed oral opioid for incisional pain.

Cevabı ve açıklamayı göster

Cevap: Withhold the metoprolol and immediately report the assessment findings to the registered nurse.

Cevap

The practical nurse should withhold the metoprolol and immediately report the assessment findings to the registered nurse.

The client is exhibiting signs of compensatory shock (hypotension, tachycardia, and oliguria) 24 hours after major abdominal surgery. Metoprolol, a beta-blocker, lowers both blood pressure and heart rate. Administering this medication would eliminate the client's compensatory tachycardia and exacerbate the hypotension. Within the scope of practice, the practical nurse must withhold the unsafe medication and immediately notify the registered nurse of the client's deteriorating condition.

Adım Adım Çözüm

Analyze the client's vital signs and clinical data.

Blood pressure is low (92/58 mm Hg), heart rate is high (116 beats/min), and urine output is low (85 mL over 4 hours, which is approximately 21 mL/hr).

To identify any physiological instability or contraindications to the scheduled medication.

Evaluate the scheduled medication against the clinical data.

Metoprolol is a beta-blocker that lowers both heart rate and blood pressure.

Administering a beta-blocker to a hypotensive, hypovolemic client will block their compensatory tachycardia and dangerously worsen the hypotension.

Determine the appropriate nursing action within the practical nurse scope of practice.

The medication must be withheld and the client's unstable condition must be reported to the registered nurse immediately.

Practical nurses must recognize deteriorating conditions, withhold unsafe medications, and escalate care to the registered nurse for advanced assessment.

Cevap: A perineal pad completely saturated with blood within 20 minutes.; Resting heart rate increasing from 76 to 114 beats per minute.; Client report of severe, unremitting perineal pressure.

Cevap

The correct findings requiring immediate notification are rapid pad saturation, a progressively increasing resting heart rate, and severe, unremitting perineal pressure.

The correct selections represent acute, life-threatening complications of postpartum adaptation. A rapidly saturated pad indicates overt hemorrhage. Tachycardia is a subtle, early compensatory mechanism for hypovolemia. Unremitting perineal pressure strongly suggests a concealed hemorrhage (hematoma). All three require emergency intervention to prevent severe hemodynamic instability.

Adım Adım Çözüm

Analyze the client's current status and risk factors.

The client is 4 hours postpartum after delivering a large-for-gestational-age infant, placing her at high risk for uterine atony, hemorrhage, and perineal trauma.

Identifying specific clinical risks guides the PN to anticipate potential life-threatening complications.

Evaluate each finding to differentiate between expected physiological adaptation and acute decompensation.

Heavy bleeding, tachycardia, and severe localized pressure indicate active or concealed blood loss. Uterine cramping during feeding, slight temperature elevation, and elevated WBCs are expected normal variants in the immediate postpartum period.

The PN must accurately interpret clinical data to avoid missing early signs of shock or escalating normal findings unnecessarily.

Determine the priority nursing action based on the identified data.

The abnormal findings threaten Airway, Breathing, and Circulation (ABCs) via hypovolemic shock and require immediate escalation to the RN for medical intervention.

Prompt recognition and reporting of clinical deterioration fall squarely within the PN scope of practice for maintaining physiological integrity.

Cevap: Ensuring that emergency suction equipment and a tracheostomy tray are immediately accessible at the bedside.; Promptly escalating a reported morning serum calcium level of 7.4 mg/dL (1.85 mmol/L) to the registered nurse.; Assessing the client's voice quality for hoarseness by asking them to speak a few words during routine checks.

Cevap

The correct actions include ensuring emergency airway equipment is at the bedside, escalating the critically low serum calcium level, and systematically assessing voice quality for laryngeal nerve damage.

Appropriate risk reduction following a thyroidectomy involves proactive preparation for airway emergencies, immediate escalation of abnormal physiological data (like a critical calcium level of 7.4 mg/dL), and targeted assessments for procedure-specific complications such as recurrent laryngeal nerve damage.

Adım Adım Çözüm

Analyze the client's postoperative context and associated physiological risks.

The client is 12 hours post-total thyroidectomy. Primary risks include airway compromise (from edema/bleeding), hypocalcemia (from parathyroid gland damage), and laryngeal nerve injury.

Identifying procedure-specific complications dictates the appropriate nursing assessments and escalation priorities.

Evaluate each nursing action against the identified post-thyroidectomy risks.

Keeping airway equipment at the bedside prepares for respiratory emergencies. Escalating a calcium of 7.4 mg/dL addresses critical hypocalcemia. Checking voice quality actively monitors for nerve damage.

Appropriate clinical actions must directly mitigate the primary risks associated with the client's specific surgery.

Evaluate the remaining actions for general safety and scope of practice violations.

Failing to report borderline vitals (HR 112, BP 100/60) ignores early signs of shock. Accepting an IV push assignment violates the PN scope of practice. Skipping two-identifier checks violates medication administration safety protocols.

Comprehensive risk reduction requires adherence to basic safety standards and legal boundaries of practice, regardless of the specific procedure.

Cevap: Withhold the oxycodone, apply supplemental oxygen, and promptly report the findings to the registered nurse (RN).

Cevap

The correct action is to withhold the oxycodone, apply supplemental oxygen, and promptly report the findings to the registered nurse (RN).

The client is demonstrating signs of significant respiratory depression (11 breaths/min) and resulting hypoxia (89% oxygen saturation), which are life-threatening adverse effects of opioid analgesics like oxycodone. Acute confusion and restlessness in an older adult are frequently the primary, early signs of hypoxia. The safest and most appropriate action within the PN scope of practice is to withhold the respiratory depressant, intervene by applying oxygen to address the immediate breathing compromise, and escalate the critical situation to the RN immediately.

Adım Adım Çözüm

Analyze the client's clinical presentation and vital signs.

The client has a low respiratory rate (11 breaths/min), hypoxia (89% oxygen saturation), and acute neurological changes (agitation, confusion).

To identify any immediate life-threatening conditions or contraindications to scheduled medications.

Correlate the assessment findings with the prescribed pharmacological therapy.

The findings represent adverse effects of oxycodone (respiratory depression) and the resulting hypoxia (manifesting as acute confusion).

Reassure the client that a sore and tight throat is expected from the breathing tube.

Administer the prescribed as-needed analgesic to relieve surgical discomfort.

Lower the head of the bed completely flat to decrease tension on the neck.

Cevabı ve açıklamayı göster

Cevap: Evaluate the client's respiratory rate, effort, and oxygen saturation.

Cevap

The nurse must first evaluate the client's respiratory rate, effort, and oxygen saturation to assess for an airway obstruction.

Following a thyroidectomy, the client is at an elevated risk for airway compromise due to localized swelling, edema, or hemorrhage (hematoma formation). Restlessness is a classic early sign of hypoxia, and the sensation of neck tightness strongly suggests physical airway compression. Applying the ABC (Airway, Breathing, Circulation) framework dictates that the nurse must assess the client's respiratory status and airway patency immediately before initiating any other intervention.

Adım Adım Çözüm

Analyze the client's clinical cues.

The client had a recent neck surgery (thyroidectomy) and is showing signs of new restlessness along with a subjective feeling of throat tightness.

Recognizing these cues is essential because the surgical site is directly adjacent to the trachea, making the client highly vulnerable to local swelling or hemorrhage.

Apply the ABC (Airway, Breathing, Circulation) priority framework.

Airway assessment becomes the immediate clinical priority over addressing pain or client positioning.

Restlessness is an early indicator of hypoxia, and a tight throat suggests possible airway compression from a hematoma, requiring urgent respiratory evaluation.

Cevap: Place a rolled towel or small blanket under the client's left ankle to suspend the heel.; Apply intermittent cold therapy packs to the surgical joint for 20 minutes at a time.; Utilize a fracture pan rather than a standard bedpan when assisting the client with elimination in bed.

Cevap

The correct interventions include suspending the heel with a rolled towel, applying intermittent cold therapy, and utilizing a fracture pan for elimination.

The correct interventions focus on preventing joint contractures by maintaining knee extension through heel suspension, utilizing intermittent cold therapy to manage local edema, and using a fracture pan to minimize painful hip and knee flexion. These actions directly support comfort and physiological integrity without risking joint deformities or compromising safety.

Adım Adım Çözüm

Analyze the surgical procedure (total knee arthroplasty) to determine specific positioning requirements.

The knee must be kept in full extension to prevent contractures. Placing anything behind the knee is contraindicated, but suspending the heel is appropriate.

Flexion contractures permanently impair mobility and surgical success.

Evaluate the impact of continuous epidural analgesia on basic care and mobility.

Epidural analgesia affects motor function, sensory perception, and sympathetic tone (blood pressure).

These physiological changes increase the risk for orthostatic hypotension and falls during initial transfers.

Differentiate between tasks appropriate for the LPN versus those requiring RN assessment or those that can be delegated to UAP.

Initial transfers for complex patients cannot be delegated to UAP. Reporting borderline vital signs is a required LPN action.

Operating strictly within the LPN scope of practice ensures client safety.

Select the basic care options that promote comfort, prevent complications, and adhere to safety standards.

Cold therapy, fracture pans, and heel suspension are selected as safe, effective basic care measures.

These interventions directly address the client's postoperative physiological needs.

Cevap

The correct interventions are elevating the left arm, assisting with left hand and wrist exercises, elevating the head of the bed to a semi-Fowler's position, and ensuring a limb alert bracelet is on the left arm.

For a client recovering from a modified radical mastectomy with axillary lymph node dissection, basic care and comfort must focus on preventing lymphedema, promoting lymphatic drainage, and ensuring adequate respiratory function. Elevating the affected arm above the level of the heart facilitates fluid return. Maintaining a semi-Fowler's position promotes comfortable lung expansion and drainage. Assisting with early, gentle hand and wrist exercises prevents contractures and promotes circulation. Placing a limb alert on the affected side is essential to prevent injury and lymphedema from venipunctures or blood pressure cuffs.

Adım Adım Çözüm

Analyze the client's surgical procedure and associated risks.

The client had a left-sided modified radical mastectomy with axillary lymph node dissection, resulting in a high risk for lymphedema on the left side and a need for specific positioning.

Understanding the anatomical changes determines the correct basic care and comfort measures.

Evaluate the positioning and comfort measures provided in the options.

Elevating the affected arm, elevating the head of the bed, and avoiding the operative side promote fluid drainage and respiratory function. Positioning on the left side is contraindicated.

Correct positioning prevents complications like edema and compromised respiratory status.

Evaluate the safety and physiological stability measures.

The left arm must be protected from trauma (e.g., blood pressure cuffs, needles). Additionally, borderline vital signs like tachycardia and hypotension must be recognized as potential shock, not ignored.

Preventing limb injury and escalating critical vital signs are essential components of safe physiological care.

Cevap: Assist with feeding while keeping the head of the bed elevated no more than 30 degrees.; Place the client on a fracture bedpan for elimination to minimize movement of the right leg.; Support the right leg with a trochanter roll to maintain proper alignment and promote comfort.

Cevap

The correct actions are to assist with feeding while keeping the head of the bed elevated no more than 30 degrees, use a fracture bedpan to minimize leg movement, and support the right leg with a trochanter roll.

Following a femoral cardiac catheterization, the client must remain on bed rest with the affected leg completely straight and the head of the bed elevated no more than 30 degrees to prevent dislodging the clot at the arterial puncture site. Using a fracture bedpan allows for elimination without excessive lifting or bending of the hips. A trochanter roll maintains alignment and prevents external rotation, promoting comfort. Assisting with feeding at a safe, low elevation ensures basic nutritional needs are met without compromising the surgical site.

Adım Adım Çözüm

Identify the physiological constraints based on the recent procedure.

The client had a right femoral cardiac catheterization, which requires strict bed rest, the right leg to be kept completely straight, and the head of the bed to be elevated no more than 30 degrees.

Bending the hip increases pressure on the femoral artery puncture site, risking severe hemorrhage.

Evaluate the proposed basic care interventions against the procedural constraints.

Feeding at a 30-degree angle, using a fracture bedpan, and applying a trochanter roll all allow for necessary ADLs while maintaining the required straight-leg and low-elevation position.

Basic care must be adapted to prioritize client safety and prevent procedural complications.

Analyze the clinical presentation and delegation tasks for safety.

Evaluating a pedal pulse is an assessment that cannot be delegated, and sudden restlessness is a critical sign of potential shock, not a baseline dementia symptom.

The PN must practice within their legal scope and prioritize physiological life-threatening changes over routine comfort measures.

Cevap: Pausing a continuous enteral tube feeding before placing a client in a supine position for a linen change.; Checking a client's most recent capillary blood glucose level prior to administering a scheduled dose of rapid-acting insulin.

Cevap

The appropriate actions that demonstrate risk reduction within the PN scope are pausing a continuous enteral tube feeding before placing a client supine, and checking a client's capillary blood glucose level prior to administering rapid-acting insulin.

Risk reduction is successfully achieved when the practical nurse adheres to safety protocols and practices within their defined scope. Pausing enteral feedings before laying a client flat prevents regurgitation and aspiration pneumonia. Checking a blood glucose level before administering rapid-acting insulin is a critical safeguard required to prevent iatrogenic hypoglycemia.

Adım Adım Çözüm

Evaluate the risk of aspiration associated with continuous enteral feedings.

Pausing the feeding before laying the client flat is identified as a necessary action to prevent aspiration.

Maintaining the head of the bed elevated during and immediately after feedings uses gravity to keep stomach contents from refluxing.

Assess the PN scope of practice regarding intravenous therapy and patient assignments.

Accepting an assignment for a client requiring titration of continuous IV heparin is identified as an action outside the PN scope.

Titrating high-risk IV medications based on laboratory values requires the comprehensive assessment skills of a registered nurse.

Analyze laboratory values in relation to scheduled medications.

Administering additional potassium to a client with a serum level of 6.1 mEq/L is identified as unsafe.

A potassium level above 5.0 mEq/L is elevated; administering more potassium could cause fatal cardiac dysrhythmias.

Review the protocol for safe administration of high-alert medications like insulin.

Checking the blood glucose level prior to insulin administration is identified as a safe, required practice.

Insulin lowers blood sugar; administering it without knowing the current level risks inducing severe hypoglycemia.

Using a room and bed number is identified as an unsafe client identification method.

Two unique, client-specific identifiers (such as name and date of birth) must be used to prevent medication errors.

Evaluate the clinical significance of vital sign trends in a client at risk for hemorrhage.

Dismissing tachycardia and decreased urine output in a bleeding client is identified as a dangerous failure to rescue.

These findings represent early compensatory mechanisms for hypovolemic shock and require immediate escalation rather than routine documentation.

Anahtar Kavram

Risk reduction involves practicing strictly within the established scope of practice, properly identifying clients using two unique identifiers, escalating critical laboratory and vital sign abnormalities, and performing procedural safeguards such as verifying blood glucose before insulin and preventing aspiration during enteral feeding.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with clearing the upper stem of medication, followed by protecting the hands with gauze, snapping the ampule away from the body, attaching a filter needle, withdrawing the medication, and finally replacing the filter needle with an appropriate injection needle.

Safe medication preparation from a glass ampule requires a specific sequence to protect both the nurse and the client. The nurse must first ensure all medication is in the lower chamber (flicking the stem) to prevent dose loss. Next, the nurse protects themselves by wrapping the neck and breaking the glass away from their body. Because breaking the glass can introduce microscopic shards into the liquid, the nurse must attach a filter needle to draw up the medication safely.

Cevap: A resting heart rate of 114 beats/min and a blood pressure of 96/58 mm Hg; New-onset restlessness and the client stating they are waiting for a train; A respiratory rate of 26 breaths/min with shallow chest expansion

Cevap

The correct findings are a resting heart rate of 114 beats/min with a blood pressure of 96/58 mm Hg, new-onset restlessness with confusion, and a respiratory rate of 26 breaths/min.

The correct options indicate acute systemic deterioration (sepsis), prioritizing Airway, Breathing, and Circulation (ABC) issues. Tachycardia with borderline hypotension suggests early shock. Tachypnea is a primary respiratory compensatory mechanism during systemic stress. Furthermore, older adults frequently exhibit acute confusion (delirium) as a primary sign of hypoxia or worsening infection.

Adım Adım Çözüm

Analyze the client's current diagnosis and primary risk factors.

The older adult client has a severe urinary tract infection, placing them at high risk for the infection spreading systemically (sepsis).

Identifying the primary risk helps distinguish expected localized symptoms from emergent systemic complications.

Evaluate vital signs for Airway, Breathing, and Circulation (ABC) compromise.

A heart rate of 114 beats/min with borderline hypotension (96/58 mm Hg) and a respiratory rate of 26 breaths/min indicate physiological stress.

ABCs are the highest priority in acute care, and these borderline vital signs are classic early indicators of shock and respiratory decompensation.

Assess for acute neurological changes compared to baseline.

New-onset restlessness and confusion (delirium) are critical acute findings, distinguishing them from the chronic gradual forgetfulness reported by the spouse.

In older adults, acute mental status changes are often the first sign of hypoxia or systemic infection.

Compare emergent findings with expected localized symptoms.

Mild suprapubic pain and cloudy urine are localized, expected findings that do not require immediate emergency escalation.

Prioritization requires the nurse to address systemic physiological instability before expected, chronic, or local symptoms.

Cevap: Notify the registered nurse immediately to report the observation.

Cevap

Notify the registered nurse immediately to report the observation.

The correct answer is to notify the registered nurse immediately. The client is exhibiting Trousseau's sign, which is an early clinical indication of hypocalcemia (low serum calcium). Because the parathyroid glands are located on the posterior surface of the thyroid, they can be inadvertently damaged or removed during a thyroidectomy. Hypocalcemia can quickly escalate to severe tetany and laryngospasm, which compromises the client's airway. Immediate escalation is required for patient safety.

Adım Adım Çözüm

Identify the clinical sign presented in the scenario.

The hand spasm that occurs during blood pressure cuff inflation is known as Trousseau's sign.

Recognizing classic clinical signs is essential for identifying underlying physiological imbalances.

Correlate the clinical sign with the client's surgical history.

The client had a total thyroidectomy. Trousseau's sign indicates hypocalcemia.

The parathyroid glands, which regulate calcium levels, are located adjacent to the thyroid and can be accidentally damaged or removed during a thyroidectomy.

Determine the priority nursing action based on the practical nurse's scope of practice.

The practical nurse must immediately notify the registered nurse.

Hypocalcemia can rapidly progress to severe tetany and life-threatening laryngospasm (airway compromise), requiring immediate RN assessment and collaborative medical intervention.

Cevabı ve açıklamayı göster

Cevap

The correct sequence ensures airway safety by first positioning the client upright, preparing the oral cavity, placing food on the strong side, using the chin-tuck maneuver during the active swallow, and finally checking for retained food.

Safe feeding for a client with dysphagia is a systematic process. Environmental and postural safety must be established first by positioning the client at 90 degrees. The oral cavity is then prepared via hygiene. During the actual feeding, food must be placed where the client has motor control (the unaffected side), and the airway must be actively protected during the swallow using the chin-tuck technique. Finally, a post-swallow assessment ensures no residual hazards remain by checking for pocketing.

Adım Adım Çözüm

Elevate the head of the bed to 90 degrees.

The client is placed in a high Fowler's position.

An upright posture enlists gravity to direct the food bolus into the esophagus and reduces the physical risk of tracheal entry.

Provide gentle oral hygiene.

The oral mucosa is moistened and sensory receptors are stimulated.

Moistening the mouth facilitates bolus formation and triggers the swallow reflex more effectively.

Place food on the unaffected side of the mouth.

Food is situated where the client has optimal muscle control.

The strong side has intact musculature to safely manipulate and propel the food backward.

Instruct the client to tuck their chin during the swallow.

The laryngeal opening is physically narrowed.

This specific postural adjustment physically protects the airway while simultaneously widening the esophageal opening.

Inspect the buccal cavities for pocketing.

The mouth is confirmed clear of residual food.

Clients with a CVA may unknowingly retain food in the affected cheek, which could be aspirated later when they lie flat or take a breath.

Cevap: Resting on the right side with a small towel roll under the puncture site

Cevap

Resting on the right side with a small towel roll under the puncture site

Positioning the client on the right side (where the liver is located) applies direct, continuous pressure to the liver capsule and the biopsy puncture site. This use of body weight, often augmented by a rolled towel, acts as a tamponade to promote hemostasis and minimize the risk of severe internal hemorrhage.

Adım Adım Çözüm

Analyze the client's recent diagnostic procedure.

The client had a percutaneous liver biopsy, which involves puncturing a highly vascular organ.

Understanding the nature of the procedure highlights the primary complication to prevent, which is severe bleeding.

Identify the goal of immediate post-procedure positioning.

The primary goal is to apply direct, continuous pressure to the puncture site to promote clotting (hemostasis).

External pressure acts as a mechanical barrier against bleeding from the internal wound.

Determine the optimal anatomical position to achieve this goal.

Placing the client on the right side compresses the liver against the chest wall. Adding a towel roll directly under the right costal margin maximizes this pressure.

The liver is located on the right side of the abdomen; therefore, right lateral positioning uses the client's own body weight to tamponade the bleeding.

Cevap: Right side-lying position with a folded towel under the puncture site

Cevap

Right side-lying position with a folded towel under the puncture site

The liver is a highly vascular organ located in the right upper quadrant of the abdomen, making bleeding the most significant risk following a biopsy. Positioning the client on their right side (often with a small towel or pillow tucked under the puncture site) utilizes the client's own body weight to apply continuous, direct pressure to the liver capsule. This splinting action is a fundamental care intervention that promotes hemostasis and prevents severe internal hemorrhage.

Adım Adım Çözüm

Identify the anatomical location of the procedure.

The liver is located in the right upper quadrant of the abdomen.

Knowing the organ's precise location dictates where external pressure must be applied.

Determine the primary physiological risk following the procedure.

Because the liver is a highly vascular organ, hemorrhage is the most significant immediate complication after a biopsy.

Identifying the primary risk guides the nurse in selecting the most critical basic care intervention.

Select the position that best mitigates the identified risk.

The right side-lying position is chosen.

This position uses the client's body weight against the mattress (often enhanced by a folded towel) to compress the liver, promoting clot formation and hemostasis.

Cevap

The correct actions are withholding enoxaparin for thrombocytopenia, reinforcing teaching about expected side effects of rifampin, and administering potassium chloride for hypokalemia.

Safe pharmacological practice for the practical nurse involves withholding enoxaparin when the platelet count is critically low to prevent hemorrhage, educating clients on harmless but startling medication side effects (like rifampin causing red-orange secretions), and appropriately treating documented electrolyte deficits (such as administering potassium for hypokalemia).

Adım Adım Çözüm

Evaluate the clinical data and prescribed medication for each client scenario.

Cevap: 10.5

Cevap

10.5

To arrive at the correct answer of

10.5

, the practical nurse must systematically process multiple conversions. First, the client's weight is converted to kilograms (

154 \div 2.2 = 70\text{ kg}

). Next, the total daily dose is calculated (

70 \times 15 = 1050\text{ mg/day}

). Because the medication is divided into two equal doses, the single dose requirement is

525\text{ mg}

. Before calculating the volume, the dispensed concentration of

0.25\text{ g/5 mL}

must be converted to milligrams (

0.25 \times 1000 = 250\text{ mg/5 mL}

). Finally, using the desired over have formula:

(525\text{ mg} \div 250\text{ mg}) \times 5\text{ mL}

equals exactly

10.5\text{ mL}

Adım Adım Çözüm

Convert the client's weight from pounds to kilograms.

154\text{ lb} \div 2.2\text{ lb/kg} = 70\text{ kg}

Weight-based dosing requires the client's weight in kilograms.

Calculate the total daily dose in milligrams.

70\text{ kg} \times 15\text{ mg/kg/day} = 1050\text{ mg/day}

This establishes the total amount of medication the client needs over a 24-hour period.

Determine the amount required for a single dose.

1050\text{ mg/day} \div 2\text{ doses} = 525\text{ mg/dose}

The prescription specifies two equally divided doses per day.

Convert the supplied medication concentration from grams to milligrams.

0.25\text{ g} \times 1000\text{ mg/g} = 250\text{ mg}

. The available concentration is

250\text{ mg}

per

5\text{ mL}

Units of measurement must match between the desired dose (mg) and the available medication supply (g) before calculating volume.

Calculate the volume to administer for a single dose.

(525\text{ mg} \div 250\text{ mg}) \times 5\text{ mL} = 2.1 \times 5\text{ mL} = 10.5\text{ mL}

Applying the standard dimensional analysis or 'Desired over Have times Volume' formula yields the exact volume to administer.
