Doxycycline 75 mg in 100 milliliters of D5W is to be administered over 1 hour using intravenous tubing with a calibration of 30gtt/mL. How many drops per minute should be given? (Only type in the number)

a) Decreasing viscosity of the tears and allowing fluid to drain away from the eye: This is incorrect. Osmotic agents do not act by affecting the viscosity of tears or enhancing drainage.
b) Increasing plasma osmolarity and drawing extracellular fluid into the blood: Osmotic agents, like mannitol, work by increasing plasma osmolarity, which draws excess fluid from the eye into the bloodstream, thereby lowering intraocular pressure.
c) Blocking production of aqueous humor: This is incorrect. Blocking production of aqueous humor is the mechanism of action of medications like beta-blockers (e.g., timolol), not osmotic agents.
d) Promoting outflow of the aqueous humor into the tear ducts: This is incorrect. Promoting outflow of aqueous humor is the mechanism of action for other medications, such as prostaglandin analogs, not osmotic agents.

a) Hypertension: Pseudoephedrine is a sympathomimetic drug that can cause vasoconstriction, leading to increased blood pressure. Clients with hypertension are at higher risk for complications such as increased blood pressure, stroke, or other cardiovascular events.
b) Overweight: While being overweight may contribute to other health concerns, it does not specifically interact with pseudoephedrine in a way that places the client at risk for harm.
c) Eczema: Eczema, a skin condition, does not directly interact with pseudoephedrine and is not a contraindication for its use.
d) Migraine headaches: Although migraine sufferers may be sensitive to certain medications, pseudoephedrine does not pose a direct risk to clients with migraines. However, caution may be needed for any individual who is sensitive to changes in blood pressure.
