A nurse is evaluating a client who has heart failure and is receiving warfarin. Which of the following statements by the client indicates a need for further teaching?
“I will use an electric razor for shaving.”
“I will eat more green leafy vegetables.”
“I will check my stools for blood.”
“I will have my blood drawn regularly.”.
The Correct Answer is B
Choice B is wrong because “I will eat more green leafy vegetables.” This statement indicates a need for further teaching because green leafy vegetables are high in vitamin K, which can antagonize the effects of warfarin and increase the risk of clotting. The client should be advised to maintain a consistent intake of vitamin K and avoid sudden changes in their diet.
Choice A is wrong because using an electric razor for shaving is a safe practice for a client who is receiving warfarin, as it reduces the risk of bleeding from cuts or nicks.
Choice C is wrong because checking stools for blood is an important measure for a client who is receiving warfarin, as it can indicate gastrointestinal bleeding, which is a serious adverse effect of the medication.
Choice D is wrong because having blood drawn regularly is necessary for a client who is receiving warfarin, as it allows the monitoring of the international normalized ratio (INR), which reflects the degree of anticoagulation and guides the dosage adjustment of the medication.
The normal range for INR for a client who is receiving warfarin is 2 to 3, unless otherwise specified by the provider.

Correct Answer is C
Explanation
Angiotensin II receptor blockers (ARBs) block the binding of angiotensin II to its receptors on blood vessels and adrenal glands, preventing its vasoconstrictive and aldosterone-stimulating effects
Choice A is wrong because beta blockers do not block angiotensin II receptors, but rather beta-adrenergic receptors, which are involved in the sympathetic nervous system.Beta blockers reduce heart rate and blood pressure by inhibiting the effects of adrenaline and noradrenaline
Choice B is wrong because calcium channel blockers do not block angiotensin II receptors, but rather calcium channels, which are involved in the contraction of smooth muscle cells.Calcium channel blockers relax blood vessels and lower blood pressure by reducing the influx of calcium into the cells
Choice D is wrong because direct acting vasodilators do not block angiotensin II receptors, but rather act directly on the smooth muscle cells of blood vessels, causing them to relax and dilate.Direct acting vasodilators lower blood pressure by decreasing peripheral resistance
