A nurse is educating a patient about how statin medications lower cholesterol. Which of the following statements accurately describes the mechanism of action of statins? Statins reduce blood cholesterol by blocking an enzyme required for cholesterol production in the liver. Statins lower serum cholesterol levels by inhibiting the intestinal absorption of cholesterol. Statins increase the number of LDL receptors on the liver, enabling the removal of more LDL cholesterol from the bloodstream. Statins can increase levels of HDL cholesterol.

Which structural difference distinguishes DNA from RNA at the sugar level?

Ordered: Humulin Regular U-100 insulin 4 units per hour.Supply: 10 units of Humulin Regular U-100 insulin in 30 mL of 0.9% Sodium Chloride.At what rate in mL/hr should the IV infuse?

Which statement best links DNA to genetic inheritance?

Ordered: ciprofloxacin hydrochloride (Cipro) 0.75 g PO q 12 hrs.Available: How many tablets will the nurse administer?   

Which residues comprise the classical catalytic triad in chymotrypsin?

The following is an excerpt from a recent scientific publication:“A protein can be identified based on each level of its structure…. The primary structure… linear chain… The quaternary structure… is formed through side‑chain interactions between 2 or more polypeptides.” What distinguishes quaternary from tertiary structure?

At a tissue pO2 of ~20–30 mmHg during exercise, which protein is more saturated with oxygen, and why?

A patient will be started on a continuous infusion of amiodarone at 0.5 mg/min. The nurse has 720 mg of amiodarone in a 500 mL bottle of D5W. What rate will the nurse program the infusion pump to deliver the amiodarone at 0.5 mg/min?

The following is an excerpt from a recent scientific publication:“Covalent molecular docking has been recently implemented in the computer‑aided drug design workflows to describe covalent interactions between inhibitors and biological targets. … these types of inhibitors derive their activity from both non‑covalent interactions and the formation of the covalent bond between the inhibitor and the target protein … covalent docking programs … integrate conventional non‑covalent docking and scoring schemes by modeling the newly formed covalent bond and the interactions occurring at the reaction site.” What key feature distinguishes covalent docking workflows compared to standard noncovalent docking?
