NSG 6435 FINAL EXAM TEST BANK ANSWERS AND EXPLANATIONS

NSG 6435 FINAL EXAM TEST BANK ANSWERS AND EXPLANATIONS 1. 1. The parent of a school-age child reports that the child usually has allergic rhinitis symptoms beginning each fall and that non-sedating antihistamines are only marginally effective, especially for nasal obstruction symptoms. What will the primary care pediatric nurse practitioner do? a. a. Order an intranasal corticosteroid to begin 1 to 2 weeks prior to pollen season. b. b. Prescribe a decongestant medication as adjunct therapy during pollen season. c. c. Recommend adding diphenhydramine to the child’s regimen for additional relief. d. d. Suggest using an over-the-counter intranasal decongestant. ANS: A Intranasal corticosteroids are a key component in long-term therapy to manage symptoms associated with AR. These should be begun 1 to 2 weeks prior to the beginning of pollen season. Decongestants are not recommended for long-term use because of side effects. Diphenhydramine causes daytime drowsiness. 1. 2. The primary care pediatric nurse practitioner sees a child for follow-up care after hospitalization for ARF. The child has polyarthritis but no cardiac involvement. What will the nurse practitioner teach the family about ongoing care for this child? a. a. Aspirin is given for 2 weeks and then tapered to discontinue the medication. b. b. Prophylactic amoxicillin will need to be given for 5 years. c. c. Steroids will be necessary to prevent development of heart disease. d. d. The child will need complete bedrest until all symptoms subside. ANS: A ASA is given for arthritis for 2 weeks and then will be tapered. Children with ARF will need penicillin prophylaxis, not amoxicillin. Steroids are sometimes used for symptomatic relief but do not prevent chronic heart disease. Bed rest is indicated only when cardiac symptoms occur. 1. 3. A school-age child with asthma is seen for a well child checkup and, in spite of “feeling fine,” has pronounced expiratory wheezes, decreased breath sounds, and an FEV1 less than 70% of personal best. The primary care pediatric nurse practitioner learns that the child’s parent administers the daily medium-dose ICS but that the child is responsible for using the SABA. A treatment of 4 puffs of a SABA in clinic results in marked improvement in the child’s status. What will the nurse practitioner do? a. a. Have the parent administer all of the child’s medications. b. b. Increase the ICS medication to a high-dose preparation. c. c. Reinforce teaching about the importance of using the SABA. d. d. Teach the child and parent how to use home PEF monitoring. ANS: D Home PEF monitoring is useful for children to identify when symptoms are worsening. This child does not appear to notice the presence of airway tightness or wheezing and so might benefit from PEF monitoring to know when to use the SABA. School-age children should be learning how to manage their chronic disease, so having the parent administer all medications is not the best choice, especially since use of the SABA is still dependent on the child’s report of symptoms. Since the child responded well to administration of the SABA, increasing the dose of ICS should not be done unless better management is not effective. Reinforcing the teaching is part of the plan but, unless the child is aware of symptoms, may not occur. 1. 4. A child has a fever and arthralgia. The primary care pediatric nurse practitioner learns that the child had a sore throat 3 weeks prior and auscultates a murmur in the clinic. Which test will the nurse practitioner order? a. a. Anti-DNase B test b. b. ASO titer c. c. Rapid strep test d. d. Throat culture ANS: B This child has symptoms and a history consistent with ARF. The ASO titer peaks in 3 to 6 weeks and will confirm a recent strep infection. The antiDNase B test will also confirm a recent strep infection, but this doesn’t peak until 6 to 8 weeks after the initial infection. A rapid strep test and throat culture do not differentiate the carrier state from a true infection. 1. 5. The primary care pediatric nurse practitioner is prescribing ibuprofen for a 25 kg child with JIA who has oligoarthitis. If the child will take 4 doses per day, what is the maximum amount the child will receive per dose? a. a. 200 mg b. b. 250 mg c. c. 400 mg d. d. 450 mg ANS: B The maximum dose is 40 mg/kg/day divided into 3 to 4 doses. 25 kg × 40 mg = 1000/4 = 250 mg. 1. 6. A school-age child who uses a SABA and an inhaled corticosteroid medication is seen in the clinic for an acute asthma exacerbation. After 4 puffs of an inhaled short-acting B2-agonist (SABA) every 20 minutes for three treatments, spirometry testing shows an FEV1 of 60% of the child’s personal best. What will the primary care pediatric nurse practitioner do next? a. a. Administer an oral corticosteroid and repeat the three treatments of the inhaled SABA. b. b. Admit the child to the hospital for every 2 hour inhaled SABA and intravenous steroids. c. c. Give the child 2 mg/kg of an oral corticosteroid and have the child taken to the emergency department. d. d. Order an oral corticosteroid, continue the SABA every 3 to 4 hours, and follow closely.
