A patient has been taking a heavy aspirin regimen for the past two months.
Which side effect, if noted by the patient, is directly related to taking high doses of aspirin?

This question assesses the monitoring of HMG-CoA reductase inhibitors. It requires understanding the pharmacological goal of atorvastatin therapy, which is the reduction of atherogenic lipids in the blood to prevent long-term cardiovascular events and stabilize atherosclerotic plaques in patients at high risk.

Choice A rationale

High-density lipoprotein (HDL) is "good" cholesterol, with a normal range ≥ 40 mg/dL for men and ≥ 50 mg/dL for women. Atorvastatin therapy aims to increase or maintain HDL, so a decrease would indicate a non-therapeutic or adverse treatment outcome.

Choice B rationale

Low-density lipoprotein (LDL) is the primary target of atorvastatin. A therapeutic response is evidenced by a decrease in LDL levels, which should ideally be ≤ 100 mg/dL in high-risk patients, as LDL is directly linked to the development of atherosclerosis.

Choice C rationale

Total cholesterol, normal range ≤ 200 mg/dL, is a measure of various lipoproteins. Atorvastatin therapy is intended to lower total cholesterol. An increase in total cholesterol would suggest that the current dosage is ineffective at achieving the desired therapeutic lipid goals.

Choice D rationale

Triglycerides, normal range ≤ 150 mg/dL, are another component of the lipid panel. While some statins have a modest effect on triglycerides, the primary goal of atorvastatin is LDL reduction, and an increase would not indicate a positive therapeutic effect for the patient.

This question focuses on emergency management of drug-induced anaphylaxis. It requires identifying the most urgent nursing action to stop the delivery of the offending antigen, which is the necessary first step to mitigate the severity of the systemic, life-threatening allergic reaction being experienced.

Choice A rationale

While providing oxygen and breathing support is a critical component of managing anaphylaxis, stopping the source of the allergen takes absolute priority to prevent further progression of the reaction, ensuring that no more of the triggering medication enters the system.

Choice B rationale

In the event of an anaphylactic reaction, stopping the infusion of the suspected medication is the immediate, non-negotiable priority. This action prevents further antigen-antibody interaction, which is the fundamental driver of the systemic release of histamine and inflammatory mediators.

Choice C rationale

Administering epinephrine is the definitive treatment for anaphylaxis and is given immediately after stopping the drug. While vital for reversing symptoms, the nurse must first disconnect the infusion to prevent ongoing exposure while they prepare to administer the life-saving medication.

Choice D rationale

Calling a Rapid Response or code team is a necessary step to bring additional resources to the bedside. However, the nurse must simultaneously stop the infusion, as every second of continued medication administration increases the potential for irreversible cardiovascular or respiratory collapse.
