Question

The nurse is educating a client newly prescribed antiepileptic drug (AED) therapy. Which statements about AED therapy are accurate? Select all that apply.

Answer 1

Correct Answers:

Abruptly stopping AEDs can increase the risk of seizure recurrence and status epilepticus.
AED therapy requires consistent blood level monitoring to ensure therapeutic effectiveness and prevent toxicity.
Clients should be advised to avoid alcohol consumption while on AED therapy due to increased CNS depression and seizure risk.

Rationale :

✳️ Abruptly stopping AEDs can increase seizure recurrence and status epilepticus — Correct

✳️ Antiepileptic drugs (AEDs) should generally not be stopped abruptly because sudden withdrawal can provoke breakthrough seizures.

✳️ In some clients, abrupt discontinuation can precipitate status epilepticus, which is a neurologic emergency.

✳️ AED doses are usually reduced gradually when therapy is being discontinued.

✳️ The tapering schedule depends on the specific medication, seizure type, dose, duration of therapy, and clinical response.

✳️ Clients should take AEDs consistently at the prescribed times to maintain stable drug concentrations.

✳️ Missed doses can lower medication levels and increase the risk for seizure recurrence.

✳️ The client should contact the prescriber before making any change to the medication regimen.

✳️ Therefore, avoiding abrupt discontinuation is an essential component of seizure safety.

✳️ AED therapy requires consistent blood level monitoring — Correct

✳️ Some AEDs require periodic serum drug-level monitoring to determine whether concentrations remain therapeutic and safe.

✳️ Medications such as phenytoin, valproate, carbamazepine, and phenobarbital are examples for which serum levels may be clinically useful.

✳️ Monitoring can help identify subtherapeutic concentrations, which can increase seizure risk.

✳️ It can also detect excessive concentrations that increase the likelihood of drug toxicity.

✳️ Laboratory monitoring is individualized because not every AED requires routine serum-level testing in every client.

✳️ Additional tests can include CBC, liver function, renal function, electrolytes, or other medication-specific monitoring.

✳️ Clinical response and adverse effects remain important even when serum drug concentrations are within the expected range.

✳️ Therefore, appropriate therapeutic drug monitoring is an important component of AED therapy.

✳️ Avoid alcohol consumption while on AED therapy — Correct

✳️ Alcohol can interact with many AEDs and increase central nervous system depression.

✳️ Combining alcohol with AEDs can worsen drowsiness, dizziness, impaired coordination, and slowed reaction time.

✳️ Alcohol can also interfere with medication adherence and alter the metabolism of certain antiepileptic medications.

✳️ Heavy alcohol use or abrupt alcohol withdrawal can independently increase the risk for seizures.

✳️ Clients with epilepsy should therefore discuss alcohol use with their healthcare provider and generally avoid or strictly limit it according to individualized guidance.

✳️ Extra caution is especially important when the AED already causes sedation or impaired coordination.

✳️ Clients should also avoid driving or operating machinery when experiencing medication-related CNS effects.

✳️ Therefore, alcohol avoidance is an important safety teaching point during AED therapy.

Answer 2

Correct Answers:

Decreased muscle spasticity

Rationale :

🖊️ Baclofen is a centrally acting skeletal muscle relaxant used primarily to manage spasticity associated with neurologic disorders.

🖊️ It acts mainly as a GABA-B receptor agonist within the spinal cord.

🖊️ This action inhibits excitatory neurotransmission and decreases excessive stimulation of motor neurons.

🖊️ The resulting reduction in motor neuron activity decreases muscle tone, spasms, and stiffness.

🖊️ Clients with cerebral palsy can develop significant spasticity that interferes with movement, positioning, comfort, and activities of daily living.

🖊️ Baclofen can therefore improve mobility, comfort, and functional ability by reducing excessive muscle contraction.

🖊️ The nurse should monitor for adverse effects such as drowsiness, dizziness, weakness, and fatigue.

🖊️ Therefore, the expected therapeutic outcome is decreased muscle spasticity.

Answer 3

Correct Answers:

Place the child on the unaffected side when administering the ear drops.
Warm the medication by gently rolling the bottle between your hands before administration.
Keep the child lying on their side for 5 minutes after administering the ear drops.
Gently shake the medication if it is in suspension form before use.

Rationale :

👉 Place the child on the unaffected side — Correct

👉 Positioning the toddler on the unaffected side places the affected ear upward for medication administration.

👉 This position allows gravity to help the medication travel into the ear canal.

👉 The caregiver should stabilize the child's head gently during administration.

👉 For a toddler younger than 3 years, the auricle is generally pulled down and back to straighten the ear canal.

👉 The dropper should be held above the canal without touching the ear to prevent contamination.

👉 The prescribed number of drops can then be instilled along the side of the canal.

👉 Proper positioning improves medication delivery and decreases unnecessary loss of the medication.

👉 Therefore, placing the child on the unaffected side is appropriate.

👉 Warm the medication between the hands — Correct

👉 Ear drops should generally be brought close to body temperature before administration.

👉 Gently rolling or holding the bottle between the hands can warm the medication safely.

👉 Instilling very cold drops can stimulate the vestibular system and cause dizziness, nausea, or discomfort.

👉 The medication should not be overheated because excessive heat can injure sensitive tissues.

👉 The caregiver should avoid using a microwave or hot water to rapidly heat the medication.

👉 Gentle hand warming provides a controlled method of increasing the medication's temperature.

👉 The medication label should always be checked for any specific storage and administration instructions.

👉 Therefore, warming the bottle gently between the hands is appropriate.

👉 Keep the child lying on their side for 5 minutes — Correct

👉 Remaining in the side-lying position after administration helps keep the medication within the affected ear canal.

👉 This allows sufficient time for the medication to contact the ear canal tissues.

👉 Immediately sitting upright can allow some medication to drain from the ear.

👉 Maintaining the position for several minutes therefore promotes effective medication distribution.

👉 The caregiver can gently engage or comfort the toddler during this period to encourage cooperation.

👉 The tragus may be gently pressed if appropriate to facilitate movement of medication through the canal.

👉 The caregiver should follow any additional positioning instructions provided with the prescribed medication.

👉 Therefore, maintaining side-lying for about 5 minutes is appropriate.

👉 Gently shake suspension medication — Correct

👉 Medications formulated as suspensions contain particles that can settle when the bottle remains stationary.

👉 Gentle shaking redistributes the medication particles throughout the liquid.

👉 Proper mixing helps ensure that each administered dose contains the intended drug concentration.

👉 Failure to mix a suspension can result in inconsistent medication dosing.

👉 The caregiver should check the medication label because not every ear-drop preparation requires shaking.

👉 When the label identifies the product as a suspension, it should be gently shaken as directed before administration.

👉 The dropper tip should remain clean and should not touch the child's ear or other surfaces.

👉 Therefore, gently shaking a suspension before use promotes accurate dosing.

Answer 4

Correct Answers:

Orthostatic hypotension causing risk of falls

Rationale :

✍️ Levodopa-carbidopa is commonly used to improve motor manifestations of Parkinson’s disease by increasing dopamine availability in the brain.

✍️ A significant adverse effect of this medication is orthostatic hypotension, which causes blood pressure to fall when the client changes position.

✍️ The client's lightheadedness and dizziness upon standing are characteristic manifestations of this adverse effect.

✍️ Orthostatic hypotension is particularly concerning because clients with Parkinson’s disease already have an increased risk for impaired balance and falls.

✍️ The nurse should immediately implement fall precautions and assist the client with position changes and ambulation.

✍️ Blood pressure and pulse should be assessed while lying, sitting, and standing when clinically appropriate.

✍️ Teaching should include changing positions slowly, sitting at the bedside before standing, and requesting assistance if dizziness occurs.

✍️ Therefore, orthostatic hypotension with increased fall risk requires priority nursing intervention.

Answer 5

Correct Answers:

"This medication helps increase dopamine in my brain, which improves my movement and coordination."

Rationale :

♦️ Parkinson’s disease involves progressive loss of dopamine-producing neurons, resulting in decreased dopamine activity within the basal ganglia.

♦️ Levodopa crosses the blood-brain barrier and is converted into dopamine in the central nervous system.

♦️ Carbidopa prevents premature conversion of levodopa to dopamine in peripheral tissues, allowing more levodopa to reach the brain.

♦️ Increasing central dopamine helps improve motor manifestations such as bradykinesia, rigidity, and tremor.

♦️ Improved dopamine activity can enhance the client's mobility, coordination, and ability to perform activities of daily living.

♦️ The medication provides symptomatic control rather than eliminating the underlying neurodegenerative disease.

♦️ The client's improved ability to perform daily activities with less tremor and rigidity indicates an appropriate therapeutic response.

♦️ Therefore, understanding that carbidopa-levodopa increases dopamine availability to improve motor function demonstrates correct understanding of its therapeutic goal.

Answer 6

Correct Answers:

Always draw up the short-acting (clear) insulin into the syringe before the intermediate-acting (cloudy) insulin to prevent contaminating the clear insulin vial with the cloudy Insulin.

Rationale :

🖍️ When regular insulin and NPH insulin are prescribed together, regular insulin is drawn into the syringe before NPH insulin.

🖍️ Regular insulin is clear, while NPH insulin normally has a cloudy appearance.

🖍️ The principle is commonly remembered as “clear before cloudy.”

🖍️ Drawing up regular insulin first prevents NPH insulin from contaminating the regular insulin vial.

🖍️ Contamination with NPH can alter the characteristics and potentially affect the action of the regular insulin remaining in the vial.

🖍️ Before preparation, NPH should be gently rolled between the palms to resuspend the insulin evenly rather than vigorously shaken.

🖍️ When preparing a mixed dose, air is typically injected into the NPH vial first and then the regular insulin vial, followed by withdrawing regular insulin first and NPH second.

🖍️ Therefore, clear before cloudy is the essential safety principle when withdrawing regular and NPH insulin into the same syringe.

Answer 7

Correct Answers:

Lactic acidosis related to metformin use

Rationale :

✏️ Metformin is a biguanide commonly prescribed as first-line therapy for type 2 diabetes mellitus.

✏️ A rare but potentially life-threatening adverse effect of metformin is lactic acidosis, caused by excessive accumulation of lactate in the bloodstream.

✏️ The risk increases when metformin accumulates, particularly in clients with significant renal impairment, severe hypoxia, or other conditions that impair lactate clearance.

✏️ Manifestations can include severe weakness, unusual fatigue, myalgia, abdominal discomfort, nausea, vomiting, and respiratory distress.

✏️ More severe cases can progress to hypotension, hypothermia, altered mental status, cardiovascular collapse, and death.

✏️ Clients should be instructed to seek immediate medical attention if manifestations suggestive of lactic acidosis develop.

✏️ Renal function should be assessed before and during metformin therapy because the kidneys are important for medication elimination.

✏️ Therefore, suspected metformin-associated lactic acidosis requires urgent evaluation because of its potentially fatal consequences.

Answer 8

Correct Answers:

Coronary artery disease

Rationale :

🔆 Sumatriptan is a selective serotonin 5-HT1B/1D receptor agonist used for the acute treatment of migraine headaches.

🔆 Its therapeutic action includes vasoconstriction of cranial blood vessels, which helps relieve migraine symptoms.

🔆 Sumatriptan can also cause coronary artery vasoconstriction, which can reduce myocardial blood flow.

🔆 Clients with coronary artery disease (CAD) are therefore at increased risk for myocardial ischemia, angina, myocardial infarction, and serious cardiac complications.

🔆 The nurse should withhold sumatriptan and notify the provider when a client has known ischemic coronary artery disease.

🔆 Sumatriptan is also contraindicated in conditions such as coronary vasospasm, uncontrolled hypertension, and certain cerebrovascular or peripheral vascular diseases.

🔆 The nurse should assess cardiovascular history and evaluate concerning symptoms such as chest pain, pressure, or tightness during therapy.

🔆 Therefore, a history of coronary artery disease is the finding that requires withholding sumatriptan and notifying the provider.

Answer 9

Correct Answers:

The hypothalamic-pituitary axis, a negative feedback loop regulating hormone secretion between the hypothalamus and pituitary gland.

Rationale :

🧿 The hypothalamic-pituitary axis is a major regulatory system that coordinates hormone secretion throughout the endocrine system.

🧿 The hypothalamus produces releasing and inhibiting hormones that regulate secretion of hormones from the anterior pituitary gland.

🧿 Pituitary hormones then stimulate target endocrine glands such as the thyroid gland, adrenal cortex, and gonads to produce their respective hormones.

🧿 As circulating concentrations of target-gland hormones increase, they typically provide negative feedback to the pituitary and hypothalamus.

🧿 Negative feedback reduces further hormone stimulation and helps maintain hormonal homeostasis within an appropriate physiologic range.

🧿 Examples include the hypothalamic-pituitary-thyroid (HPT) axis, hypothalamic-pituitary-adrenal (HPA) axis, and hypothalamic-pituitary-gonadal (HPG) axis.

🧿 Disruption at the hypothalamic, pituitary, or target-gland level can therefore produce characteristic patterns of hormonal excess or deficiency.

🧿 Therefore, the hypothalamic-pituitary axis operating largely through negative feedback best explains how these structures regulate systemic hormone levels.

Answer 10

Correct Answers:

To prevent the medication from draining into the tear duct and reduce systemic absorption, minimizing potential adverse effects.

Rationale :

🌹 After administering ophthalmic medication, gentle pressure should be applied over the inner canthus to occlude the nasolacrimal duct.

🌹 This technique is known as punctal or nasolacrimal occlusion.

🌹 Without occlusion, medication can drain through the nasolacrimal duct into the nasal cavity.

🌹 The highly vascular nasal mucosa can absorb ophthalmic medications into the systemic circulation.

🌹 Systemic absorption can produce significant adverse effects, particularly with medications such as ophthalmic beta blockers used to treat glaucoma.

🌹 For example, systemic absorption of timolol can contribute to bradycardia, hypotension, and bronchospasm in susceptible clients.

🌹 Applying gentle pressure for the recommended period helps keep more medication localized within the eye while reducing systemic exposure.

🌹 Therefore, pressure at the inner canthus is used primarily to decrease nasolacrimal drainage and systemic medication absorption.
