A patient with a new prescription for a HMG-CoA (statin) drug is instructed to take the

Correct Answer: D

Rationale: The nurse's best response is D: "This timeframe correlates better with the natural diurnal rhythm of cholesterol production." This explanation is accurate and helps the patient understand the rationale behind the timing of taking the HMG-CoA (statin) drug. Cholesterol production in the body typically follows a natural diurnal rhythm, with cholesterol synthesis peaking during the night. By taking the statin medication in the evening, it aligns with the body's cholesterol production pattern, making it more effective in reducing cholesterol levels. This explanation supports the patient's understanding of the importance of timing in maximizing the medication's effectiveness.

Correct Answer: D

Rationale: When administering heparin subcutaneously, the nurse should use a - to -inch needle. This needle length is appropriate for subcutaneous injections as it ensures the medication is being injected into the fatty tissue layer beneath the skin. Using a longer needle can result in the medication being injected too deeply, potentially causing complications. Additionally, the nurse should not aspirate the syringe before injecting the medication, massage the site after injection, or apply heat to the injection site when administering heparin subcutaneously.

Correct Answer: B

Rationale: A med management box organizes doses, reducing forgotten pills in older adults with memory issues, boosting compliance. Crushing meds risks altering pharmacokinetics (e.g., enteric-coated drugs). Doctor review is proactive but not direct compliance. More education assumes understanding drives adherence, often untrue. The box addresses forgetfulness, a practical fix.

Correct Answer: B

Rationale: Protamine is the antidote for Heparin. Heparin is an anticoagulant medication that prevents the formation of blood clots. In case of an overdose of Heparin or if there is a need to reverse its effects quickly (such as during surgery), Protamine is administered as the specific antidote. Protamine works by binding to Heparin and neutralizing its anticoagulant effects. Therefore, Protamine is the appropriate antidote to counteract the effects of Heparin.

Correct Answer: C

Rationale: Heroin's appeal comes from its metabolism to morphine , which activates μ-opioid receptors for euphoria. Dopamine , epinephrine , norepinephrine , and serotonin (E) aren't direct products. Morphine's potency drives addiction in this overdose case.
