Question 2 of 5
A child diagnosed with ADHD is to receive a total of 20 mg of dextroamphetamine daily in two divided doses. The dextroamphetamine on hand is supplied in 5-mg tablets. How many tablet(s) should the nurse administer for the morning dose?

Question 3 of 5
The hospitalized child who has a blood lead level of 50 mcg/dL is to receive succimer 10 mg/kg oral capsule q8h for 5 days. The child weighs 20 kg. Which intervention by the student nurse should be corrected by the observing nurse?
Correct Answer: A
Rationale: A: The 20-kg child should receive two capsules of succimer (Chemet), not one. Dose (mg) = 20 kg x 10 mg/kg = 200 mg. B: Succimer capsules can be opened and sprinkled on a small amount of food or in liquid to be swallowed; two 100-mg capsules = 200 mg, which is the correct dose. C: Fluids should be increased to prevent renal damage because succimer is excreted by the kidneys. D: Succimer forms a water-soluble compound with lead, allowing urinary elimination of excessive amounts of lead. Lead is removed from the blood, and theoretically some lead is removed from tissues and organs.
Question 4 of 5
The nurse telephones the HCP to request a pm anxiolytic medication order for a hospitalized client having occasional anxiety. Which medication, if prescribed, should the nurse question regarding its effectiveness for prn use?
Correct Answer: A
Rationale: Buspirone (BuSpar) has a 10- to 14-day delay in therapeutic onset, making it unsuitable for prn use.
Question 5 of 5
The client with COPD is prescribed salmeterol diskus inhaler and fluticasone Rotadisk inhaler. Which instruction should the nurse include to prevent the client from developing oropharyngeal candidiasis?
Correct Answer: B
Rationale: A: Drinking fluids before inhaler use may moisten the mouth, but it does not prevent oropharyngeal candidiasis. B: Oropharyngeal candidiasis is a yeast infection that occurs in the mouth due to destruction of the normal flora with the use of a glucocorticoid inhaler (fluticasone [Advair]). The nurse should instruct the client to rinse the mouth after using the glucocorticoid inhaler to prevent its occurrence. C: For best effectiveness, the client should wait 5 minutes between medications, but this has no effect on prevention of oropharyngeal candidiasis. D: This describes the correct technique for using an inhaler but does not reduce the risk of developing oropharyngeal candidiasis.
