The nurse is reviewing the laboratory data of a client diagnosed with coronary artery disease. Which set of laboratory results indicates a need for client teaching regarding dietary modifications?
A. Cholesterol 200 mg/dL; HDL 35 mg/dL; triglycerides 190 mg/dL
This option is not correct because the cholesterol level is within the normal range of less than 200 mg/dL¹, the HDL level is slightly low but not too far from the recommended level of over 40 mg/dL for men and over 50 mg/dL for women¹, and the triglyceride level is also within the normal range of less than 150 mg/dL¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications.
B. Cholesterol 120 mg/dL; HDL 50 mg/dL; triglycerides 140 mg/dL
This option is not correct because the cholesterol level is low, the HDL level is high, and the triglyceride level is normal. These are all desirable results that reflect a low risk of coronary artery disease¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications.
C. Cholesterol 180 mg/dL; HDL 40 mg/dL; triglycerides 220 mg/dL
This option is correct because the cholesterol level is high, the HDL level is low, and the triglyceride level is high. These are all unfavorable results that reflect a high risk of coronary artery disease¹. High cholesterol and triglycerides can lead to plaque buildup in the arteries, which can cause atherosclerosis and reduce blood flow to the heart². Low HDL can also increase the risk of heart disease because it does not help remove LDL (bad cholesterol) from the arteries². Therefore, this set of laboratory results indicates a need for dietary modifications, such as reducing saturated and trans fats, increasing fiber, and limiting alcohol³.
D. Cholesterol 165 mg/dL; HDL 54 mg/dL; triglycerides 160 mg/dL
This option is not correct because the cholesterol level is normal, the HDL level is high, and the triglyceride level is normal. These are all desirable results that reflect a low risk of coronary artery disease¹. Therefore, this set of laboratory results does not indicate a need for dietary modifications..

Similar Questions
The nurse is assisting a client diagnosed with hypertension with menu selection. Which items should the nurse suggest?
A. Fried chicken, baked beans, French fries, and cake
This is a high-fat, high-sodium, and high-calorie meal that is not suitable for a client with hypertension. Fried foods, processed meats, and baked beans are sources of saturated fat and sodium that can raise blood pressure and cholesterol levels. Cake is a source of added sugar that can contribute to obesity and diabetes.
B. Tomato soup, fried flounder, white rice, and a grapefruit
This is a moderate-fat, moderate-sodium, and moderate-calorie meal that is not ideal for a client with hypertension. Fried flounder and tomato soup are sources of fat and sodium that can increase blood pressure. White rice is a refined carbohydrate that can spike blood sugar levels and increase the risk of diabetes.
C. Barbecue pulled pork sandwich, fresh green beans, mashed potatoes, and ice cream
This is a high-fat, high-sodium, and high-calorie meal that is not appropriate for a client with hypertension. Barbecue pulled pork sandwich, mashed potatoes, and ice cream are sources of saturated fat and sodium that can elevate blood pressure and cholesterol levels. Fresh green beans are the only healthy component of this meal.
D. Baked tuna, fresh broccoli, brown rice, and fresh cantaloupe
This is a low-fat, low-sodium, and low-calorie meal that is suitable for a client with hypertension. Baked tuna, fresh broccoli, brown rice, and fresh cantaloupe are sources of lean protein, fiber, complex carbohydrates, vitamins, minerals, and antioxidants that can lower blood pressure and cholesterol levels, prevent obesity and diabetes, and promote cardiovascular health.

The nurse is reviewing the chart of a client with an indication of myocardial infarction or unstable angina. Which laboratory test result(s) should the nurse recognize as an indication of myocardial injury? (Select all that apply)
A. Elevated troponins
Elevated troponins. This is a correct answer. Troponins are proteins that regulate the myocardial contractile process². They are released into the bloodstream when the myocardial cells are damaged by ischemia or infarction². Troponins are highly specific and sensitive indicators of myocardial injury². The normal range for troponin I is less than 0.03 ng/mL and for troponin T is less than 0.01 ng/mL².
B. Decreased homocysteine levels
Decreased homocysteine levels. This is not a correct answer. Homocysteine is an amino acid that is involved in the metabolism of methionine². Elevated homocysteine levels are associated with an increased risk of cardiovascular disease, but they are not a direct marker of myocardial injury². The normal range for homocysteine is 5 to 15 micromol/L².
C. Elevated CK-MB
his is a correct answer. CK-MB is one of the isoenzymes of creatine kinase, an enzyme that catalyzes the conversion of creatine to phosphocreatine, which is used for energy storage in the muscles². CK-MB is found mainly in the myocardium and is released into the blood when the myocardial cells are injured². CK-MB is a specific and sensitive marker of myocardial injury, but it is less specific than troponins². The normal range for CK-MB is 0 to 3 ng/mL².
D. Decreased alkaline phosphatase (ALP)
Decreased alkaline phosphatase (ALP).This is not a correct answer. ALP is an enzyme that is found in various tissues, such as the liver, bone, intestine, and placenta². ALP is not a marker of myocardial injury, and its levels are not affected by ischemia or infarction². The normal range for ALP is 30 to 120 U/L².
E. Increased platelet count
Increased platelet count.This is not a correct answer. Platelets are blood cells that are involved in hemostasis and clot formation². Increased platelet count, or thrombocytosis, can be a sign of inflammation, infection, malignancy, or other conditions². Platelet count is not a marker of myocardial injury, and it does not reflect the extent of ischemia or infarction². The normal range for platelet count is 150,000 to 450,000 per microliter of blood².

The nurse is about to administer the combination medication chlorthalidone and atenolol to a client diagnosed with chronic hypertension. Which interventions should the nurse include in the plan of care? (Select all that apply)
A. Administer if the blood pressure is 90/60 and monitor for side effects
Chlorthalidone and atenolol are used to treat hypertension⁴⁵. However, administering the medication when the blood pressure is 90/60 might not be advisable. This is because atenolol, a beta-blocker, can further lower the heart rate and blood pressure¹¹⁷. Therefore, it's important to monitor the patient's blood pressure before administration¹.
B. Hold if the heart rate is less than 60 beats per minute
Atenolol can slow the heart rate¹¹⁷. If the heart rate is already less than 60 beats per minute, which is the lower limit of the normal range¹, the medication should be held and the healthcare provider should be notified⁵.
C. Teach to dangle feet before standing
One of the side effects of atenolol and chlorthalidone is dizziness or lightheadedness¹¹⁷. Teaching the patient to dangle their feet before standing can help prevent orthostatic hypotension, a form of low blood pressure that happens when you stand up from sitting or lying down¹¹.
D. Encourage to limit the intake of potassium-rich foods
Chlorthalidone is a diuretic that can cause the body to lose potassium¹¹⁷. However, atenolol does not have this effect⁵. Therefore, it's not necessary to limit the intake of potassium-rich foods unless advised by a healthcare provider.
E. Monitor fluid intake and output
Monitoring fluid intake and output is important when administering diuretics like chlorthalidone⁵. This can help ensure the patient is not becoming dehydrated and help monitor the medication's effectiveness¹¹.
