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?
Regular exercise.
Stress reduction.
Smoking cessation.
Low-fat diet.
The Correct Answer is C
Choice A Reason: This is incorrect because regular exercise is a beneficial lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a greater impact on reducing the risk of cardiovascular events and mortality.
Choice B Reason: This is incorrect because stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a more direct effect on improving the function and structure of the blood vessels and heart.
Choice C Reason: This is correct because smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease, as smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction.
Choice D Reason: This is incorrect because a low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Smoking cessation has a stronger influence on lowering the levels of cholesterol and inflammation in the blood.

Correct Answer is D
Explanation
Choice A reason: Switching to a non-rebreather mask is not the immediate action to take. Non-rebreather masks deliver a high concentration of oxygen, typically reserved for severe hypoxia. The patient’s oxygen saturation is low, but not critically low. It’s important to first ensure the accuracy of the reading before escalating oxygen delivery methods.
Choice B reason: Removing the nasal cannula is not advisable. The patient is postoperative and may have impaired gas exchange due to anesthesia, pain, or decreased mobility. Removing the supplemental oxygen may worsen the patient’s hypoxemia and increase the risk of complications.
Choice C reason: Increasing the oxygen to 3 L/minute could be a potential action if the oxygen saturation reading is accurate and the patient’s condition does not improve. However, any changes to a patient’s oxygen therapy should be made under the guidance of a healthcare provider. It’s important to first verify the accuracy of the oxygen saturation reading.
Choice D reason: Verifying the placement of the pulse oximeter is the highest priority action. Before making changes to the oxygen flow rate, it’s important to ensure that the oxygen saturation reading is accurate. Incorrect placement or function of the pulse oximeter could lead to inaccurate readings.
Correct Answer is D
Explanation
Choice A Reason: Massaging the injection site can cause bruising and bleeding, and is not recommended for subcutaneous heparin injections.
Choice B Reason: Rotating injections between different body sites can increase the risk of hematoma formation and skin irritation, and is not advised for subcutaneous heparin injections.
Choice C Reason: Expelling the air in the prefilled syringe can result in a loss of medication dose, and is not necessary for subcutaneous heparin injections.
Choice D Reason: Injecting in the abdominal area at least 2 inches from the umbilicus is the correct technique for subcutaneous heparin injections, as it reduces the risk of injury to blood vessels and nerves, and ensures consistent absorption of the medication.
