A nurse is caring for a male client who is undergoing screening tests for atherosclerosis. Which of the following laboratory findings should the nurse identify as an increased risk for this disorder?
Cholesterol level 195 mg/dL
Elevated HDL levels
Elevated LDL levels
Triglyceride level 135 mg/dL
The Correct Answer is C
Choice A reason: A cholesterol level of 195 mg/dL is not an increased risk for atherosclerosis, because it is within the normal range of less than 200 mg/dL. Cholesterol is a type of fat that circulates in the blood and can contribute to plaque formation in the arteries.
Choice B reason: Elevated HDL levels are not an increased risk for atherosclerosis, because HDL stands for high-density lipoprotein, which is the "good" cholesterol that helps to remove excess cholesterol from the blood and prevent plaque formation in the arteries.
Choice C reason: Elevated LDL levels are an increased risk for atherosclerosis, because LDL stands for low-density lipoprotein, which is the "bad" cholesterol that can deposit in the arterial walls and cause plaque formation and narrowing of the arteries.
Choice D reason: A triglyceride level of 135 mg/dL is not an increased risk for atherosclerosis, because it is within the normal range of less than 150 mg/dL. Triglycerides are another type of fat that circulates in the blood and can contribute to plaque formation in the arteries.

Correct Answer is C
Explanation
Choice A reason: This is an incorrect action, because covering the insertion site with a hydrocolloid dressing can prevent air from escaping and cause a subcutaneous emphysema, which is a complication of chest tube removal. The insertion site should be covered with a sterile gauze dressing and taped on three sides.
Choice B reason: This is an important action, but not the first one. The nurse should provide pain medication before removal, not immediately after, to reduce the discomfort and anxiety of the client.
Choice C reason: This is the correct action, because auscultating the lungs after removal can help assess the respiratory status and detect any signs of pneumothorax, such as diminished or absent breath sounds.
Choice D reason: This is an incorrect action, because delegating removal of the chest tube to an AP is beyond the scope of practice and can cause harm to the client. The removal of the chest tube should be performed by the nurse or the provider.
Correct Answer is D
Explanation
Choice A reason: This is a normal finding, not an indication of breast cancer. Lumps that are mobile and tender upon palpation prior to a menstrual period are usually benign and related to hormonal changes.
Choice B reason: This is a normal finding, not an indication of breast cancer. Multiple round masses that are tender and found in both breasts are usually benign and related to fibrocystic breast changes.
Choice C reason: This is a normal finding, not an indication of breast cancer. Bilaterally darkened areolas are usually benign and related to genetic factors, pregnancy, or aging.
Choice D reason: This is an abnormal finding, and an indication of breast cancer. A nontender hard lump that is palpated in one breast is usually malignant and related to abnormal cell growth.
