Question 1 of 5
The client has a new prescription for metoclopramide. The nurse notifies the HCP because the client has a contraindication for metoclopramide use. Which information in the client's medical record most likely prompted the nurse's notification of the HCP?
Correct Answer: C
Rationale: A: The use of NG suctioning alone would not prevent metoclopramide use. Metoclopramide can be administered through the NG tube; the tube is then clamped for an hour after administration until absorption occurs. B: Metoclopramide should be used with caution with DM, but it is not contraindicated. C: The client's history of a seizure disorder would contraindicate the use of metoclopramide. Because metoclopramide (Reglan) blocks dopamine receptors in the chemoreceptor trigger zone of the CNS, it is contraindicated in seizure disorders. D: Metoclopramide is used in the treatment of nausea and vomiting for clients receiving chemotherapy.
Question 2 of 5
The 17-year-old female is about to have a drug screen test for employment. The adolescent tells the nurse of a recent UTI that was treated with antibiotics. Which antibiotic, if identified by the client, could produce a false-positive urine screening test for opioids?
Correct Answer: D
Rationale: A: Cephalexin (Keflex) does not interfere with urine testing for opioids. B: Ceftazidime (Fortaz), a cephalosporin, does not interfere with urine testing for opioids. C: Amoxicillin (Amoxil), an aminopenicillin, does not interfere with urine testing for opioids. D: Fluoroquinolones, such as ciprofloxacin (Cipro), can cause false-positive urine opiate screens.
Question 3 of 5
Oral ranitidine 2 mg/kg twice daily is prescribed for the infant weighing 16 lb 8 oz. The medication is supplied as 15 mg/mL. How many milliliters should the nurse instruct the parent to withdraw in the syringe provided with the ranitidine to administer one dose?
Correct Answer: 1
Rationale: Use a proportion formula to calculate the dose. First determine the dose for the child's weight: 16 lb 8 ounces = 16.5 lb/ 2.2 lb/kg = 7.5 kg. Next determine the prescribed dose: 7.5 kg x 2 mg = 15 mg. The medication is supplied in 15 mg per 1 mL. The dose to administer is 1 mL of ranitidine (Zantac).
Question 4 of 5
The client undergoing detoxification from chronic alcohol abuse is to receive Phenobarbital 120 mg IM and promethazine 50 mg IM. Which explanation by the nurse about using this medication combination is correct?
Correct Answer: B
Rationale: Promethazine (Phenergan) potentiates the CNS depression of phenobarbital, producing a greater sedative effect.
Question 5 of 5
The nurse is assessing the client with herpes zoster. The nurse determines that acyclovir is an effective treatment when which finding is noted?
Correct Answer: B
Rationale: A: Drying and crusting of genital lesions would indicate acyclovir's effectiveness for treating genital herpes, not herpes zoster. B: Herpes zoster produces painful vesicular skin eruptions along the course of a nerve. Crusting and healing of the vesicular skin lesions indicate that acyclovir (Zovirax) is effective. C: Urticaria (swollen, raised areas) and pruritus (itching) are not symptoms of herpes zoster. D: The lesions of chicken pox are generalized, whereas herpes zoster lesions occur along the course of a nerve. Herpes zoster occurs when the chicken pox (varicella zoster) virus that has incorporated itself into nerve cells is reactivated years after the initial infection, but it is not chicken pox.
