Chest pain, dyspnea, or rapid weight gain may indicate worsening cardiac status and require immediate report.
Before you read
Test yourself first: 5 questions
Question 1 of 5
A nurse is teaching a client with coronary artery disease about lifestyle changes to reduce cardiac risk. Which statement by the client indicates a need for FURTHER teaching?
Answer: B. Replacing exercise with rest is incorrect; clients with stable CAD should engage in regular moderate aerobic activity as tolerated, which improves cardiovascular health and lowers risk. Smoking cessation, a diet low in saturated fat and sodium, and stress management are all appropriate and accurate cardiac risk-reduction measures.
Question 2 of 5
A nurse provides teaching about preventing iodine-deficiency goiter in a community. Which dietary recommendation is appropriate?
Answer: B. Adequate dietary iodine prevents simple (iodine-deficiency) goiter and supports normal thyroid hormone production. Using iodized salt and consuming iodine-containing foods such as seafood and dairy meets the body's iodine needs. Avoiding all iodine would promote, not prevent, goiter.
Question 3 of 5
A client recovering at home after surgery asks how to prevent wound infection. The nurse teaches to:
Answer: B. Perform hand hygiene before wound care, keep the incision clean and dry, follow dressing instructions, eat a protein-rich diet, and report increasing redness/drainage/fever. Touching the wound with dirty hands invites infection.
Question 4 of 5
A nurse is teaching a client newly prescribed warfarin after a pulmonary embolism. Which client statement indicates correct understanding of the diet?
Answer: A. Clients on warfarin should keep their intake of vitamin K consistent rather than suddenly increasing it, because vitamin K-rich foods like leafy greens antagonize warfarin and can change the INR. Eliminating greens entirely is unnecessary; consistency is the goal.
Question 5 of 5
A client with a new colostomy is concerned about gas and odor. Which dietary teaching by the nurse is appropriate?
Answer: B. Gas-forming and odor-producing foods such as cabbage, broccoli, cauliflower, beans, onions, eggs, and carbonated beverages can be limited to reduce flatus and odor. The nurse should teach the client to introduce foods gradually and identify individual triggers rather than impose broad, unnecessary restrictions.
Keep the streak going with more questions like these, each with a full rationale.
What is cardiac diet?
It is prescribed for hypertension, coronary artery disease, heart failure, and after myocardial infarction. The goal is to control blood pressure, lower cholesterol, and reduce cardiac workload.
Key points to remember
- Sodium is usually limited to about 2,000 mg per day to control blood pressure and fluid.
- Saturated and trans fats are reduced to lower LDL cholesterol; fried and fatty foods are avoided.
- Soluble fiber, omega-3 fish, and unsaturated fats support cardiovascular health.
- The DASH eating pattern emphasizes fruits, vegetables, low-fat dairy, and whole grains.
- Caffeine and alcohol are moderated, and patients on warfarin keep vitamin K intake consistent.
Nursing priorities
- Teach reduction of sodium and saturated fat with practical food swaps.
- Monitor blood pressure, weight, and lipid trends.
- Reinforce consistent vitamin K intake if the patient takes warfarin.
- Coordinate with the dietitian for an individualized heart-healthy plan.
- Assess understanding of label reading for sodium and fat content.
Labs & values
Patient teaching
- Bake, grill, or broil instead of frying.
- Choose lean meats, fish, and plant proteins, and trim visible fat.
- Read labels for sodium and saturated fat, and flavor with herbs not salt.
- Keep leafy green and vitamin K intake steady if you take warfarin.
Red flags: report now
- Chest pain, dyspnea, or rapid weight gain may indicate worsening cardiac status and require immediate report.
- Never advise large erratic swings in vitamin K foods for warfarin patients, as it disrupts anticoagulation.
- Sudden 2 to 3 lb daily weight gain in heart failure signals fluid retention.
