A client arrives at the healthcare setting currently taking atorvastatin (Lipitor) daily. Which assessment finding associated with atorvastatin (Lipitor) would need immediate reporting to the healthcare provider?
bradycardia
dark-red urine
elevated HDL cholesterol
migraine headache
The Correct Answer is B
A. Bradycardia is not a common side effect of atorvastatin and would not necessarily require immediate reporting unless it is significantly low and symptomatic.
B. Dark-red urine could indicate the presence of myoglobinuria, which can occur due to rhabdomyolysis, a serious side effect of statins like atorvastatin that necessitates immediate medical attention.
C. Elevated HDL cholesterol is generally a positive finding and does not require reporting unless it is part of a larger adverse effect context.
D. A migraine headache, while concerning, is not a known side effect specifically associated with atorvastatin and may not require immediate intervention unless severe or persistent.

Correct Answer is A
Explanation
A. Diphenhydramine is an H1 antihistamine that works by blocking the effects of histamine at H1 receptor sites, thus alleviating allergy symptoms.
B. H2 receptor sites are primarily involved in gastric acid secretion, and diphenhydramine does not affect these receptors.
C. Diphenhydramine does not stimulate histamine effects; it blocks them instead.
D. The medication does not occupy all H receptor sites; it specifically targets H1 receptors to exert its effects.
Correct Answer is B
Explanation
A. Diarrhea is not a direct risk of stopping TPN abruptly.
B. Abruptly stopping TPN can cause hypoglycemia because the high glucose content in TPN leads to increased insulin production. Without the continuous glucose infusion, blood sugar levels can drop rapidly.
C. Hypovolemia is not a common outcome from stopping TPN suddenly.
D. Erythema at the site is unrelated to the cessation of TPN and more commonly related to local site reactions or infection.
