Question 3 of 5
An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How would bacterial glycocalyx contribute to this?
Correct Answer: A
Rationale: The bacterial glycocalyx is a sticky, gelatinous substance that surrounds the bacterial cell wall. It helps protect the bacteria from antibiotic and immunologic destruction by forming a barrier that prevents antibiotics and immune cells from effectively reaching and eliminating the bacterial infection. This protection allows the bacteria to persist and cause persistent infections, even when antibiotics are administered through the catheter.
Question 4 of 5
Which of the following statements regarding colloid administration does the nurse identify as being true?
Correct Answer: A
Rationale: Colloids, such as albumin and synthetic colloids like hydroxyethyl starch, do not enhance the oxygen-carrying capacity of the blood. They can help to increase the intravascular volume in cases of hypovolemia by osmotically drawing fluid into the intravascular space. This can help improve tissue perfusion by increasing blood pressure. Colloids do not have a direct effect on oxygen-carrying capacity or coagulation properties. Dextran therapy can cause adverse effects like anaphylaxis or renal failure, but it is not a general contraindication for all colloid administration in the treatment of hypovolemia.
Question 5 of 5
A patient with coronary artery disease asks the nurse about the good cholesterol laboratory values. The nurse knows that good cholesterol refers to which lipids?
Correct Answer: D
Rationale: High-density lipoproteins (HDLs) are often referred to as the "good cholesterol" because they help remove excess cholesterol from the bloodstream back to the liver for processing and excretion. Higher levels of HDL cholesterol are associated with a reduced risk of coronary artery disease and other cardiovascular diseases. A higher HDL level is considered beneficial for heart health, while lower levels are associated with an increased risk of heart disease. Monitoring HDL cholesterol levels is important in the management of coronary artery disease and assessing cardiovascular risk.
