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) Triazolam orally at bedtime:
Triazolam is a benzodiazepine medication used for its sedative and anxiolytic properties. It can cause daytime sedation and impair psychomotor function, making activities such as driving hazardous. Instructing the client to avoid performing such activities while taking triazolam ensures their safety and minimizes the risk of accidents.

B) Polyethylene glycol dissolved in 240 ml of water once daily:
Polyethylene glycol is a osmotic laxative used to treat constipation. It does not cause sedation or impair cognitive function, so there is no need to avoid hazardous activities while taking this medication.

C) Adalimumab subcutaneously every 2 weeks:
Adalimumab is a biologic medication used to treat autoimmune diseases such as rheumatoid arthritis and inflammatory bowel disease. It does not typically cause sedation or impair cognitive function, so hazardous activities are generally not restricted while taking adalimumab.

D) Ketoconazole orally once daily with food:
Ketoconazole is an antifungal medication that does not usually cause sedation or impair cognitive function. There is no specific restriction on hazardous activities while taking ketoconazole unless the client experiences unusual side effects affecting alertness or coordination, which should be discussed with a healthcare provider.

A. Serum calcium 10.5 mg/dL B. Serum potassium 5.2. C. Serum chloride 99 mEq/L D. Serum sodium 140 mEq/L

Correct Answer is B

Explanation

A) Serum calcium 10.5 mg/dL:
A serum calcium level of 10.5 mg/dL is within the normal range (8.5-10.5 mg/dL). Spironolactone does not typically affect calcium levels significantly.

B) Serum potassium 5.2 mEq/L:
An elevated serum potassium level (hyperkalemia) is a known adverse effect of spironolactone. Spironolactone is a potassium-sparing diuretic that inhibits aldosterone, leading to decreased potassium excretion and potential hyperkalemia, especially in clients with impaired renal function.

C) Serum chloride 99 mEq/L:
A serum chloride level of 99 mEq/L is within the normal range (96-106 mEq/L). Spironolactone does not typically affect chloride levels significantly.

D) Serum sodium 140 mEq/L:
A serum sodium level of 140 mEq/L is within the normal range (135-145 mEq/L). Spironolactone does not typically affect sodium levels significantly.
