Question 2 of 5
The HCP prescribes 1200 mL of TPN solution to be administered over 24 hours for the homebound client. The home health nurse should instruct the client to set the infusion pump to deliver how many mL per hour?
Correct Answer: 50
Rationale:
To calculate the infusion rate, divide the total volume by the total time: 1200 mL/ 24 hours = 50 mL per hour. The nurse should instruct the client to set the infusion pump to deliver 50 mL per hour.
Question 3 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 4 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.
Question 5 of 5
The nurse is preparing to care for the 14-month-old newly hospitalized toddler with bacterial gastroenteritis and severe dehydration. Which initial collaborative interventions should the nurse expect to implement? Select all that apply.
Correct Answer: A,C,F
Rationale: A: Antibiotics may be prescribed to treat bacterial gastroenteritis to ensure complete recovery. B: Oral fluid rehydration will be initiated later, but not initially, when the toddler presents with severe dehydration. C: The child who presents with severe dehydration needs IV therapy to stabilize the balance of fluids and electrolytes. D: The pain and discomfort the toddler will have are due to fever and cramping from the GI illness; thus, analgesics are usually not prescribed. E: An antidiarrheal medication is contraindicated. F: Fever is often a symptom of gastroenteritis. Ensuring that the fever is controlled will provide some comfort.
