A client is to receive a continuous infusion of IV Insulin at 6 units per hour. Pharmacy delivers a concentration of 75 units of regular insulin in 150 mL of NSS. At what rate should the nurse set the IV pump?

Answer and Explanation

The Correct Answer is ["12"]

Calculate the dilution factor of the insulin solution:
- Dilution factor = Total volume / Insulin units
- Dilution factor = 150 mL / 75 units
- Dilution factor = 2 mL/unit
Determine the volume of the insulin solution needed to deliver 6 units/h:
- Volume = Desired dosage * Dilution factor
- Volume = 6 units/h * 2 mL/unit
- Volume = 12 mL/h

Correct Answer is D

Explanation

A. Constipation is not a direct consequence of external beam radiation to the lung; it may occur due to other factors, such as reduced mobility or medications, but it is not specifically anticipated from this treatment.
B. Alopecia is typically associated with radiation therapy to areas where hair grows, such as the head, rather than the lung area, so it is not expected in this case.
C. Increased saliva is not a common side effect of radiation to the lungs; rather, some patients may experience dry mouth due to treatment to nearby structures.
D. Esophagitis is a well-known complication of radiation therapy to the chest area, as the esophagus can be affected by radiation exposure, leading to inflammation and discomfort in swallowing.

A. limit episodes of anticipatory and delayed emesis B. lessen the client's risk of developing neutropenia C. decrease time intervals between remission D. broaden range of cell kill while minimizing toxicities to the client

Correct Answer is D

Explanation

A. While limiting emesis is important in cancer treatment, combination chemotherapy primarily focuses on improving efficacy and minimizing toxicities, not specifically targeting nausea and vomiting episodes.
B. Combination chemotherapy can actually increase the risk of neutropenia due to the cumulative effects of multiple agents, as each may independently lower white blood cell counts.
C. Decreasing time intervals between remission is not a primary goal of combination chemotherapy; rather, it aims to achieve better overall treatment outcomes.
D. The main rationale for using combination chemotherapy is to broaden the range of cancer cell kill through different mechanisms of action while minimizing the side effects associated with higher doses of a single agent. This approach can improve treatment efficacy and reduce the likelihood of resistance.
