2.The PaO2is low (normal is 80 to 100);therefore, the nurse should administeroxygen via a nasal cannula. Oxygen isconsidered a medication.3. The ABGs are not normal and interven-tion is needed.4. The client’s ABGs reveal a low arterialoxygen level and do not need to be verifiedby a pulse oximeter reading.30.1. Amiodarone, an antiarrhythmic, sup-presses ventricular ectopy and is the drugof choice for this arrhythmic. The nursewould not question this order.2. Lidocaine, an antiarrhythmic, suppressesventricular ectopy. The nurse would notquestion this order.3. Defibrillation is the treatment of choicefor a client in ventricular fibrillation.4.Pacemakers are used for clients diag-nosed with symptomatic sinus bra-dycardia or asystole. This client is inventricular fibrillation; therefore, thenurse would question this order.A Child Experiencing Poisoning31. 1.The child must receive supportive careto maintain life until the poison can beidentified and further specific measurescan be implemented.2.Treatment is facilitated by identifyingthe specific poison and the amountingested, then specific treatment can beinstituted.3.Limiting the amount of poison absorbedby the body can limit the damage.4.Measures to eliminate the poison fromthe body prevent further absorption.5.An antidote is administered to counter-act the effects of the poison.32.1. Charcoal does not change the pH of asubstance.2.Charcoal binds with the poison toform an inert substance that can beeliminated through the bowel becausethe body is incapable of absorbingcharcoal molecules. The charcoal mustbe administered within 60 minutes ofingesting the poison. The feces will beblack.3. Charcoal can absorb the antidote. Char-coal should not be administered before,with, or immediately after the antidote.4. Charcoal does not cause emesis. An emeticsuch as ipecac would induce vomiting.33.1. Gastric lavage would not be contrain-dicated for a 2-year-old child in a comawho ingested the contents of a bottle ofacetaminophen (Tylenol).2. Gastric lavage would not be contrain-dicated for a 3-year-old child who ate abottle of unknown tablets.3.Gastric lavage should not be attemptedwhen there has been ingestion of caus-tic agents, convulsions are occurring,high-viscosity petroleum productshave been ingested, cardiac arrhyth-mias are present, or there is emesis ofblood. Antidotes, supportive care, andprevention of aspiration are imple-mented if gastric lavage is not to beperformed.4. Gastric lavage would not be contraindi-cated for a 10-year-old who took prescrip-tion painkillers.34. 1.Ipecac, an emetic, stimulates vomiting,which can remove the medication fromthe stomach. It takes 20 to 30 minutesto work.2. Telemetry monitoring is not as impor-tant as preparing the parent for the child’sresponse to the medication. It is hopedthat the medication will be removed fromthe child’s system before significant impacton the heart can occur.
