A client with a family history of cardiac disease is seeking information to control risk factors. Which lifestyle modification is most important for the nurse to encourage?
Smoking cessation.
Low-fat diet.
Stress reduction.
Regular exercise.
The Correct Answer is A
Choice A rationale
Smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease. Smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction. Quitting smoking has a more direct effect on improving the function and structure of the blood vessels and heart, significantly reducing the risk of cardiovascular events and mortality.
Choice B rationale
A low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. While it helps in lowering cholesterol levels and reducing inflammation, smoking cessation has a stronger influence on overall cardiovascular health.
Choice C rationale
Stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Although managing stress can improve heart health, smoking cessation has a more immediate and significant impact on reducing cardiovascular risks.
Choice D rationale
Regular exercise is beneficial for preventing and managing cardiac disease, but it is not the most important lifestyle modification. Exercise helps in maintaining a healthy weight, lowering blood pressure, and improving overall cardiovascular health, but smoking cessation has a greater impact on reducing the risk of cardiovascular events.

Correct Answer is A
Explanation
Choice A rationale
Injecting in the abdominal area at least 2 inches (5.1 cm) from the umbilicus is the correct technique for subcutaneous heparin injections. This reduces the risk of injury to blood vessels and nerves and ensures consistent absorption of the medication.
Choice B rationale
Rotating injections between the abdomen and gluteal areas is not recommended for low molecular weight heparin (LMWH) injections. The abdomen is the preferred site for consistent absorption.
Choice C rationale
Massaging the injection site to increase absorption is not recommended for LMWH injections. Massaging can cause bruising and affect the absorption of the medication.
Choice D rationale
Expelling the air in the prefilled syringe prior to injection is not recommended for LMWH injections. The air bubble helps ensure the entire dose is administered and prevents medication from leaking out.
Correct Answer is B
Explanation
Choice A rationale
Whether the popsicles contain pulp or fruit is not relevant to the clear liquid diet, which focuses on the clarity and digestibility of the liquids.
Choice B rationale
The color and flavor of gelatin used are important because certain colors, especially red or purple, can interfere with medical tests and are often avoided in clear liquid diets.
Choice C rationale
If the popsicles are completely frozen is not relevant to the dietary restrictions. The focus should be on the ingredients and their suitability for a clear liquid diet.
Choice D rationale
The number of popsicles available does not impact their suitability for the child’s diet. The nurse should focus on the content and appropriateness of the popsicles.
