A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DSW). The nurse should set the pump to deliver how many mL/hr?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["100"]

To calculate the infusion rate, use the formula:

mL/hr = (volume of solution in mL / time of infusion in hr) x 60 min/hr

Plug in the given values:

mL/hr = (50 mL / 0.5 hr) x 60 min/hr

Simplify and solve:

mL/hr = 100 x 60 min/hr

mL/hr = 100 mL/hr

Round to the nearest whole number and add a leading zero if needed:

mL/hr = 100 mL/hr

Correct Answer is A

Explanation

Radiation therapy can cause immunosuppression, which increases the risk of infection. The nurse should monitor the client for signs of infection such as fever, chills, malaise, or purulent drainage.

Examine the skin for generalized urticaria. This is not a common side eﬀect of radiation therapy, as urticaria is an allergic reaction that causes hives or welts on the skin. Radiation therapy can cause localized skin irritation, erythema, or dryness, but not generalized urticaria.
Review laboratory test results for low hemoglobin. This is not a direct eﬀect of radiation therapy, as hemoglobin is a component of red blood cells that carries oxygen in the blood. Radiation therapy can cause anemia, which is a low number of red blood cells, but not necessarily low hemoglobin.
Monitor the mouth for signs of xerostomia. This is not relevant for a client who receives radiation therapy to treat lung cancer, as xerostomia is dry mouth caused by reduced salivary gland function. This can occur in clients who receive radiation therapy to treat head and neck cancer, but not lung cancer.

A. A client who has had radiation therapy for head and neck cancer B. A client who has had prolonged diarrhea C. A client who has had a cerebrovascular accident D. A client who has lactose intolerance E. A client who is 4 hr postoperative following a leg amputation with general anesthesia

Correct Answer is ["A","C","E"]

Explanation

These clients have impaired swallowing, gag reﬂex, or level of consciousness, which increase their risk of aspiration while eating.

The other options are not correct because:

b. A client who has had prolonged diarrhea does not have a direct risk factor for aspiration, as diarrhea aﬀects the lower gastrointestinal tract and not the upper airway or esophagus.

d. A client who has lactose intolerance does not have a risk factor for aspiration, as lactose intolerance causes abdominal cramps, bloating, gas, or diarrhea when consuming dairy products, but does not aﬀect the ability to swallow or protect the airway.
