A nurse is assisting in the education of a group of clients about the contraindications of warfarin therapy. Which of the following statements is appropriate to include in the instructions?

"Clients who have rheumatoid arthritis should not take warfarin."

"Clients who have diabetes mellitus type 1 should not take warfarin"

"Clients who have hypertension should not take warfarin"

"Clients who are pregnant should not take warfarin"

Answer and Explanation

The Correct Answer is D

A) "Clients who have rheumatoid arthritis should not take warfarin":
Rheumatoid arthritis itself is not a contraindication for warfarin therapy. However, close monitoring is required due to potential interactions with medications used to treat rheumatoid arthritis and the increased risk of bleeding associated with both conditions.

B) "Clients who have diabetes mellitus type 1 should not take warfarin":
Type 1 diabetes mellitus is not a contraindication for warfarin therapy. However, diabetes increases the risk of complications such as peripheral vascular disease, which may necessitate careful monitoring of INR levels and adjustments to warfarin dosage.

C) "Clients who have hypertension should not take warfarin":
Hypertension alone is not a contraindication for warfarin therapy. However, hypertension is a risk factor for cardiovascular diseases that may require anticoagulation therapy. Close monitoring of blood pressure and potential interactions with antihypertensive medications is essential.

D) "Clients who are pregnant should not take warfarin":
Pregnancy is a contraindication for warfarin therapy due to its teratogenic effects, which can cause fetal harm or birth defects. Pregnant clients requiring anticoagulation therapy may be prescribed alternative medications that are safer during pregnancy, under the guidance of a healthcare provider.

Correct Answer is A

Explanation

A) Regular insulin:
Regular insulin is a short-acting insulin that acts quickly to lower blood glucose levels. It is suitable for managing diabetic ketoacidosis (DKA), which presents with symptoms such as confusion, flushed skin, and a fruity or acetone odor on the breath. Regular insulin helps to reduce ketone production and normalize blood glucose levels rapidly.

B) Glargine:
Glargine is a long-acting insulin that provides basal insulin coverage over an extended period. It is not typically used for the acute management of diabetic ketoacidosis due to its slow onset and prolonged duration of action.

C) NPH (Neutral Protamine Hagedorn):
NPH insulin is an intermediate-acting insulin that has a slower onset and duration compared to regular insulin. It is not the first choice for treating diabetic ketoacidosis due to its slower action.

D) Detemir:
Detemir is a long-acting insulin analogue that provides basal insulin coverage. Similar to glargine, it is not ideal for the acute treatment of diabetic ketoacidosis due to its slower onset and extended duration of action.

Correct Answer is ["7.5"]

Explanation

We can calculate the volume of potassium chloride solution to administer using the following steps:

Identify the prescribed dose: The nurse needs to administer 20 mEq of potassium chloride.

Identify the concentration of available solution: The potassium chloride liquid is available in a concentration of 40 mEq/15 mL. This means there are 40 milliequivalents (mEq) of potassium chloride in every 15 milliliters (mL) of the solution.

Set up a proportion to find the volume needed:

Desired dose (mEq) : Volume to administer (mL) = Concentration (mEq/mL)

Plug in the values:

20 mEq : Volume to administer (mL) = 40 mEq/15 mL

Solve for the volume:

To isolate the volume (mL), multiply both sides of the proportion by the volume unit (mL) and divide by the dose (mEq).

Volume to administer (mL) = (20 mEq) x (mL) / (40 mEq/15 mL)

We can simplify the calculation before dividing:

Volume to administer (mL) = (20 mEq x 15 mL) / 40 mEq

Volume to administer (mL) = 300 mL / 40 mEq

Volume to administer (mL) = 7.5 mL (round to one decimal place)

Therefore, the nurse should administer 7.5 mL of the potassium chloride solution.
