The nurse is teaching a client about reducing the risk for coronary artery disease. An elevation in which laboratory value is most directly associated with atherosclerosis, leading to coronary artery disease?
 
  1. Total cholesterol
  2. Very low-density lipoprotein (VLDL)
  3. Low-density lipoprotein (LDL)
  4. High-density lipoprotein (HDL)

Question 2

The nurse is caring for a client diagnosed with coronary artery disease. When examining the results of laboratory tests, the nurse notes that which findings are consistent with this diagnosis?
 
  1. Decreased total serum cholesterol and LDL, and elevated HDL
  2. Elevated total serum cholesterol, LDL, and HDL
  3. Elevated total serum cholesterol and LDL, and decreased HDL
  4. Decreased total serum cholesterol, LDL, and HDL

Answer to Question 1

Correct Answer: 3
Rationale 1: Total cholesterol represents the sum of all types of cholesterol. An elevation in total cholesterol is not the most direct predictor of atherosclerosis risk.
Rationale 2: Very low-density lipoprotein (VLDL) is a precursor of LDL and thus does not have the most direct relationship with initiation of atherosclerosis.
Rationale 3: The strength of the association between LDL cholesterol and atherosclerosis is demonstrated by the direct relationship between reduction in LDL cholesterol and acute coronary syndrome risk. LDL cholesterol contains lipoprotein (a), which is highly associated with atherosclerotic plaque.
Rationale 4: High-density lipoprotein (HDL) carries cholesterol from the peripheral tissues to the liver for metabolism and excretion, so an elevation rather than a decrease in HDL is associated with lowered atherosclerosis risk.
Global Rationale: The strength of the association between LDL cholesterol and atherosclerosis is demonstrated by the direct relationship between reduction in LDL cholesterol and acute coronary syndrome risk. LDL cholesterol contains lipoprotein (a), which is highly associated with atherosclerotic plaque. Total cholesterol represents the sum of all types of cholesterol. An elevation in total cholesterol is not the most direct predictor of atherosclerosis risk. Very low-density lipoprotein (VLDL) is a precursor of LDL and thus does not have the most direct relationship with initiation of atherosclerosis. High-density lipoprotein (HDL) carries cholesterol from the peripheral tissues to the liver for metabolism and excretion, so an elevation rather than a decrease in HDL is associated with lowered atherosclerosis risk.

Answer to Question 2

Correct Answer: 3
Rationale 1: Decreased total serum cholesterol and LDL are inconsistent with coronary artery disease because LDL reflects the amount of cholesterol that is being transported from the liver to peripheral tissue. An elevation in HDL is inconsistent with coronary artery disease because this value reflects how much cholesterol is being carried from the peripheral tissue to the liver for metabolism and excretion.
Rationale 2: Elevated total serum cholesterol and LDL are consistent with coronary artery disease because LDL reflects the amount of cholesterol that is being transported from the liver to peripheral tissue. An elevation in HDL is inconsistent with coronary artery disease because this value reflects how much cholesterol is being carried from the peripheral tissue to the liver for metabolism and excretion.
Rationale 3: Elevated total serum cholesterol is consistent with coronary artery disease. Increased LDL is consistent with coronary artery disease because LDL reflects the amount of cholesterol that is being transported from the liver to peripheral tissue. A decrease in HDL is inconsistent with coronary artery disease because this value reflects how much cholesterol is being carried from the peripheral tissue to the liver for metabolism and excretion.
Rationale 4: Decreased total serum cholesterol is inconsistent with coronary artery disease, and decreased LDL is inconsistent with coronary artery disease because low-density lipoprotein level reflects the amount of cholesterol that is being transported from the liver to peripheral tissue. A decrease in high-density lipoprotein is consistent with coronary artery disease because this value reflects how much cholesterol is being carried from the peripheral tissue to the liver for metabolism and excretion.
Global Rationale: Elevated total serum cholesterol is consistent with coronary artery disease. Increased LDL is consistent with coronary artery disease because LDL reflects the amount of cholesterol that is being transported from the liver to peripheral tissue. A decrease in HDL is inconsistent with coronary artery disease because this value reflects how much cholesterol is being carried from the peripheral tissue to the liver for metabolism and excretion.

Great answer, keep it coming :)

 

Did you know?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made. The mixture of cocaine, saliva, and resin numbed the site enough to allow hours of drilling.

Did you know?

Vampire bats have a natural anticoagulant in their saliva that permits continuous bleeding after they painlessly open a wound with their incisors. This capillary blood does not cause any significant blood loss to their victims.

Did you know?

The average older adult in the United States takes five prescription drugs per day. Half of these drugs contain a sedative. Alcohol should therefore be avoided by most senior citizens because of the dangerous interactions between alcohol and sedatives.

Did you know?

Studies show that systolic blood pressure can be significantly lowered by taking statins. In fact, the higher the patient's baseline blood pressure, the greater the effect of statins on his or her blood pressure.

Did you know?

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
