A client is discharged with a prescription for warfarin. Which discharge instruction should the nurse emphasize to the client?

Take a multi-vitamin supplement daily.

Use an astringent for superficial bleeding.

Add large amounts of spinach to the diet.

Avoid going barefoot, especially outside.

Answer and Explanation

The Correct Answer is D

Choice A reason: Taking a multi-vitamin supplement daily is not a necessary instruction for a client taking warfarin, which is an anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors and prevents blood clots. However, some vitamins, such as vitamin K, vitamin E, and vitamin C, can interact with warfarin and affect its effectiveness. Patients should consult their health care provider before taking any supplements or herbal products.

Choice B reason: Using an astringent for superficial bleeding is not a sufficient instruction for a client taking warfarin, which is an anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors and prevents blood clots. Warfarin can increase the risk of bleeding, both internally and externally. Patients should report any signs of bleeding, such as bruising, nosebleeds, gum bleeding, blood in urine or stool, or prolonged bleeding from cuts or wounds, to their health care provider. They should also avoid activities or products that can increase the risk of bleeding, such as shaving with a razor, using dental floss, or taking aspirin or NSAIDs.

Choice C reason: Adding large amounts of spinach to the diet is an incorrect instruction for a client taking warfarin, which is an anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors and prevents blood clots. Spinach is a leafy green vegetable that is high in vitamin K, which can counteract the effect of warfarin and increase the risk of clotting. Patients should maintain a consistent intake of vitamin K-rich foods and avoid sudden changes in their diet.

Choice D reason: Avoiding going barefoot, especially outside, is a correct instruction for a client taking warfarin, which is an anticoagulant that inhibits the synthesis of vitamin K-dependent clotting factors and prevents blood clots. Warfarin can increase the risk of bleeding, both internally and externally. Patients should protect their feet from injury or infection by wearing shoes or slippers at all times.

Correct Answer is D

Explanation

Choice A reason: Trouble sleeping is not a relevant information for administering pyridostigmine, which is a cholinesterase inhibitor that improves muscle strength and function in patients with myasthenia gravis. Trouble sleeping may be caused by other factors, such as stress, pain, or medication side effects.

Choice B reason: Difficulty with urination is not a pertinent information for administering pyridostigmine, which does not affect urinary function or bladder control. Difficulty with urination may indicate a urinary tract infection, prostate enlargement, or kidney stones.

Choice C reason: Unexplained weight loss is not a significant information for administering pyridostigmine, which does not affect metabolism or appetite. Unexplained weight loss may be a sign of an underlying condition, such as hyperthyroidism, diabetes, or cancer.

Choice D reason: Recent oral intake is the correct information for administering pyridostigmine, which should be taken on an empty stomach or before meals to enhance its absorption and effectiveness. Pyridostigmine can also help prevent or reduce dysphagia (difficulty swallowing), which is a common symptom of myasthenia gravis.

A. Platelet count of 100,000/mm³ (100 x 10^9/L). B. Hematocrit 45% (0.45 volume fraction). C. Blood urea nitrogen (BUN) 20 mg/dL (7.1 mmol/L). D. Serum creatinine 1.0 mg/dL (88.4 μmol/L).

Correct Answer is A

Explanation

Choice A reason: Platelet count of 100,000/mm³ (100 x 10^9/L) is below the normal range and indicates thrombocytopenia, which is a decrease in the number of platelets in the blood. Thrombocytopenia can increase the risk of bleeding and bruising, and can be a serious adverse effect of enoxaparin. This laboratory result requires immediate action by the nurse, such as notifying the prescriber, monitoring for signs of bleeding, and withholding the next dose of enoxaparin.

Choice B reason: Hematocrit 45% (0.45 volume fraction) is within the normal range and does not indicate any problem with the client's red blood cells or oxygen-carrying capacity.

Choice C reason: Blood urea nitrogen (BUN) 20 mg/dL (7.1 mmol/L) is within the normal range and does not indicate any problem with the client's kidney function or hydration status.

Choice D reason: Serum creatinine 1.0 mg/dL (88.4 μmol/L) is within the normal range and does not indicate any problem with the client's kidney function or muscle metabolism.
