The nurse is teaching a patient with heart failure about dietary modifications to reduce fluid retention and improve cardiac function. Which of the following foods should the nurse advise the patient to limit or avoid?
Fresh fruits and vegetables
Whole grains and cereals
Lean meats and poultry
Canned soups and sauces.
The Correct Answer is D
The nurse should advise the patient with heart failure to limit or avoid canned soups and sauces because they are high in sodium, which can cause fluid retention and worsen cardiac function. Sodium intake should be restricted to less than 2 g per day for patients with heart failure.
Choice A is wrong because fresh fruits and vegetables are good sources of potassium, magnesium, and fiber, which are beneficial for heart health. Potassium and magnesium help regulate fluid and electrolyte balance, and fiber helps lower cholesterol and blood pressure.
Choice B is wrong because whole grains and cereals are also rich in fiber, as well as complex carbohydrates, which provide energy and prevent rapid fluctuations in blood glucose levels. Whole grains and cereals may also contain phytochemicals that have antioxidant and anti-inflammatory effects.
Choice C is wrong because lean meats and poultry are low in saturated fat and cholesterol, which can contribute to atherosclerosis and coronary artery disease. Lean meats and poultry provide protein, which is essential for tissue repair and wound healing. Protein intake should be adequate but not excessive for patients with heart failure, as too much protein can increase the workload of the kidneys.

Correct Answer is B
Explanation
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 B
Explanation
Diuretics are drugs that increase the excretion of water and sodium by the kidneys, reducing blood volume and blood pressure.Diuretics lower blood pressure by dilating peripheral arterioles and decreasing blood volume by increasing the excretion of sodium and water.
Choice A is wrong because angiotensin-converting enzyme (ACE) inhibitors do not increase the excretion of water and sodium by the kidneys.ACE inhibitors block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor and stimulator of aldosterone secretion.By reducing angiotensin II levels, ACE inhibitors lower blood pressure by dilating blood vessels and decreasing sodium and water retention.
Choice C is wrong because adrenergic drugs do not increase the excretion of water and sodium by the kidneys. Adrenergic drugs act on the sympathetic nervous system, which regulates heart rate, blood pressure, and other functions. Depending on the type and location of adrenergic receptors, adrenergic drugs can have different effects on blood pressure. Some adrenergic drugs can increase blood pressure by stimulating alpha receptors, which cause vasoconstriction.Other adrenergic drugs can decrease blood pressure by stimulating beta receptors, which cause vasodilation and decreased cardiac output.
Choice D is wrong because direct acting vasodilators do not increase the excretion of water and sodium by the kidneys. Direct acting vasodilators are drugs that relax the smooth muscle of blood vessels, causing them to widen and lower blood pressure.Direct acting vasodilators do not affect the renin-angiotensin-aldosterone system or the sympathetic nervous system, which regulate sodium and water balance.
