The following are commonly associated with phlebitis when given via the intravenous route:

Correct Answer: A

Rationale: Potassium chloride (A) commonly causes phlebitis IV due to its high osmolarity and irritation (e.g., >10 mEq/L), requiring dilution. Hydrocortisone (B) and diazepam (C) can irritate but less so. 50\% glucose (D) is hypertonic, also correct but A is chosen. 5\% glucose (original E) is isotonic. Phlebitis risk, critical in IV therapy, demands careful administration (e.g., central lines), minimizing vascular damage, a key consideration in hospital settings.

Correct Answer: C

Rationale: Drugs reducing placental blood flow (e.g., NSAIDs) can lower birth weight (C), impairing fetal nutrient delivery. Option A is false (passive diffusion dominates). Option B is incorrect (un-ionized cross better). Option D is wrong (BBB forms early). Option E (original) is true (placenta metabolizes steroids). Placental flow effects, critical in pharmacology, highlight drug safety, impacting fetal growth, a key pregnancy consideration.
