A nurse is preparing to administer 40 mg of furosemide IV. Available is furosemide 10 mg/mL. How many mL should the nurse administer per dose?
The Correct Answer is ["4"]
Step 1: Determine the dosage required. Required dosage = 40 mg
Step 2: Determine the concentration of the available solution. Available concentration = 10 mg/mL
Step 3: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 40 mg ÷ 10 mg/mL
Step 4: Perform the division. 40 ÷ 10 = 4
= The nurse should administer 4 mL.

Correct Answer is D
Explanation
Choice A reason:
Stop taking the pills and switch to a different contraceptive method: This is not necessary for a single missed dose. Stopping the pills entirely and switching methods would be an overreaction and could lead to unnecessary complications. The standard recommendation for a missed dose is to take it as soon as remembered and continue with the regular schedule.
Choice B reason:
Take a home pregnancy test: Taking a home pregnancy test is not required immediately after missing a single dose of oral contraceptives, especially if it is the first week of the cycle. Pregnancy tests are typically recommended if there is a significant delay in the menstrual cycle or if multiple doses are missed.
Choice C reason:
Do not have vaginal intercourse until after your next period: This advice is overly cautious for a single missed dose. While it is important to use backup contraception if multiple doses are missed, abstaining from intercourse until the next period is not necessary for just one missed pill.
Choice D reason:
Take the missed dose now, then continue the medication as ordered: This is the correct course of action. According to guidelines, if a single hormonal pill is missed, it should be taken as soon as possible, and the next pill should be taken at the usual time. This may mean taking two pills in one day, but it ensures continuous contraceptive protection.
Correct Answer is D
Explanation
Choice A reason:
Family history of cardiac disease is a non-modifiable risk factor. This means it cannot be changed or controlled through lifestyle or behavioral modifications. A family history of heart disease increases an individual’s risk, but it is not something that can be altered.
Choice B reason:
Increasing age is another non-modifiable risk factor. As people age, their risk for cardiovascular disease naturally increases. This is due to the cumulative effects of aging on the cardiovascular system, which cannot be changed.
Choice C reason:
The diagnosis of diabetes mellitus is a complex risk factor. While the presence of diabetes itself is not modifiable, the management of diabetes through lifestyle changes, medication, and diet can significantly reduce cardiovascular risk. However, the condition itself remains a non-modifiable risk factor.
Choice D reason:
Cigarette smoking is a modifiable risk factor. This means that individuals can reduce their risk of cardiovascular disease by quitting smoking. Smoking cessation has been shown to significantly lower the risk of heart disease and improve overall cardiovascular health.
