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 C
Explanation
This is because metoprolol is a beta blocker, which can block the beta-2 receptors in the lungs and cause constriction of the airways.This can lead to breathing problems such as shortness of breath, cough, and wheezing. Bronchospasm is more likely to occur in people who have asthma or chronic obstructive pulmonary disease (COPD).
Choice A is wrong because tachycardia, or fast heart rate, is not an adverse effect of metoprolol. In fact, metoprolol can lower the heart rate by blocking the beta-1 receptors in the heart.A normal resting heart rate for adults ranges from 60 to 100 beats per minute (bpm).Metoprolol can cause bradycardia, or slow heart rate, which can be a serious side effect if it is too low.
Choice B is wrong because hyperglycemia, or high blood sugar, is not an adverse effect of metoprolol. Metoprolol does not affect the insulin secretion or glucose metabolism in the body.A normal blood sugar level for adults without diabetes is less than 140 mg/dL (7.8 mmol/L) two hours after eating. Metoprolol can cause hypoglycemia, or low blood sugar, in people who have diabetes and take insulin or other glucose-lowering medications.This is because metoprolol can mask the symptoms of hypoglycemia, such as palpitations and tremors.
Choice D is wrong because hyperkalemia, or high potassium, is not an adverse effect of metoprolol. Metoprolol does not affect the potassium balance in the body.
A normal blood potassium level for adults is 3.6 to 5.2 millimoles per liter (mmol/L)
Correct Answer is D
Explanation
Warfarin is an anticoagulant that prevents blood clots from forming or growing larger. It works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. The INR (international normalized ratio) is a measure of how long it takes the blood to clot.The therapeutic range for INR depends on the indication for warfarin therapy, but for atrial fibrillation, it is usually between 2 and 3. An INR level of 3.5 is above the therapeutic range, which means the blood is too thin and the patient is at risk of bleeding. The nurse should hold the warfarin dose and notify the physician, who may order vitamin K to reverse the effects of warfarin.
Choice A) Administer vitamin K as ordered by physician is wrong because vitamin K is not indicated unless the physician orders it based on the patient’s condition and INR level.
Vitamin K is an antidote for warfarin overdose and can reverse its anticoagulant effects.
However, administering vitamin K without a physician’s order may cause the INR to drop below the therapeutic range and increase the risk of clotting.
Choice B) Administer heparin as ordered by physician is wrong because heparin is another anticoagulant that works by activating antithrombin, a natural inhibitor of clotting factors.
Heparin is used for acute treatment of thromboembolic disorders, such as deep vein thrombosis or pulmonary embolism.
It is not indicated for atrial fibrillation unless there is evidence of acute thrombosis.
Administering heparin to a patient with an elevated INR would increase the risk of bleeding.
Choice C) Administer warfarin as ordered by physician is wrong because warfarin is the cause of the elevated INR and should be withheld until the INR returns to the therapeutic range.
Continuing to administer warfarin would further increase the INR and the risk of bleeding.
