P. 235
correct answer ✅Carbamazepine depresses transmission in the nucleus ventralis anterior of the thalamus. This area is associated with the spread of seizure discharge. Exact mechanism of action not known but may work by slowing sodium influx to the cortical neurons thus slowing the spread of abnormal neuron activity. What should families be taught regarding the monitoring of seizure activity? - correct answer ✅Seizure triggers, when to contact the physician, how to take medications properly and that medication needs may change with patient growth (kids), need for monitoring blood levels, signs of adverse drug reactions What electrolyte imbalance is noted with the administration of topiramate (Topamax)? P. 239 - correct answer ✅Topiramate is a carbonic anhydrase inhibitor used for seizures and migraines. This can increase bicarb loss (via the
kidneys) which decreases serum bicarb levels. The result is hyperchloremic metabolic acidosis. What is the pregnancy category for valproate? - correct answer ✅Pregnancy category D (FDA dropped Pregnancy category designations June 2015) What instructions will you provide to a woman who wants to get pregnant and has a seizure disorder controlled with valproate? P. 278-279 - correct answer ✅She should be advised to speak with her neurologist before trying to get pregnant.

Most significant risk is cardiac conduction disorder mostly in peds and elderly. May develop sinus tachycardia due to slowing of depolarization of the cardiac muscle

SSNIs-headache, somnolence, dizziness, insomnia, nervousness, nausea, dry mouth, constipation, and abnormal ejaculation; decreased appetite and weight loss. Norepinephrine reuptake inhibitors (NRIs)- nausea, vomiting, insomnia, fatigue, weight loss, somnolence, nervousness, dry mouth, blurred vision, diarrhea, and constipation. MAOIs -
insomnia, anxiety, anticholinergic effects, dizziness, headaches, restlessness, and hypotension What receptors do the benzodiazepines act on? P. 267 - correct answer ✅GABA receptors What factors will place the patient at risk for antibiotic resistance? P. 692-693 - correct answer ✅Bacteria can undergo genetic mutations or acquire resistance. Excessive or Inappropriate use (ex, viral use). Over-use of broad spectrum antibiotics. Not completing course of therapy What factors place the patient at risk for hypersensitivity reactions with penicillins and cephalosporins? P. 695-709 - correct answer ✅Each class contains a Beta-lactam ring. What are the safest antibiotics to prescribe to a woman who is pregnant? P. 705-708 - correct answer ✅Most penicillins (Amoxicillin, Amox-Clav), and cephalosporins are considered safe pregnancy. Tetracyclines (doxycycline and minocycline) and quinolones should be avoided with pregnancy.
or the periapical region of teeth or perforation of the oral mucosa: Patients with prosthetic cardiac valves or prosthetic material used for cardiac valve repair. Patients with previous infective endocarditis. Patients with congenital heart defect (CHD). Unrepaired cyanotic CHD, including palliative shunts and conduits. Completely repaired congenital heart defect repaired with prosthetic material or device, whether placed by surgery or by catheter intervention, during the first 6 months after the procedure. Repaired CHD with residual defects at the site or adjacent to the site of a prosthetic patch or prosthetic device (both of which inhibit endothelialization). Cardiac transplant recipients with valve regurgitation due to a structurally abnormal valve. What patient teaching will you provide to a patient who is experiencing non- infectious diarrhea related to antibiotic administration? P. 695 - correct answer ✅Increase fluids , Fresh yogurt in restoring good flora in the GI system , Donnagel-(attapulgite is an absorbent), Anitperistaltic agent not recommended (retain toxins) A patient is taking a fluoroquinolone; what are the most serious adverse effects? P. 721 - correct answer ✅Tendonitis and tendon rupture , C. diff infection, Hypersensitivity reactions, Stevens-Johnsons Syndrome (Rash eyes, nose, mouth, genitals- skin dies and heals after rash)

They do so mainly by binding to the 30S ribosomal subunit in the mRNA translation complex. What are the most common drug interactions with the fluoroquinolone levofloxacin (Levaquin)? - correct answer ✅Levofloxacin should not be used with NSAIDs, concurrent use increases CNS stimulation and seizures, Antacids- interfere with GI absorption, resulting in decreased serum levels, Anticoagulants- anticoagulant effect is increased, Antineoplastic agents- fluoroquinolone is decreased, Cimetidine- interferes with elimination of fluoroquinolone, Cyclosporins-increase nephrotoxic effects, Glucocorticoids- increase risk of tendon rupture, Theophylline- decreased clearance of theophylline and toxicity
