Answer:
a. Atenolol is a beta-blocker, while Hydrochlorothiazide is a diuretic.  
b. Atenolol and Hydrochlorothiazide can be used together to decrease the blood pressure and to slow the heart rate down.
c. The patient needs to have into consideration that both medications may cause irregular heartbeats, dizziness, weakness and fainting.
Explanation:
Atenolol is a beta-blocker, it means that this drug slows down the heart rate by changing how the body responds to nerve impulses, which enhances the pumping of blood. Moreover, Hydrochlorothiazide is a diuretic or 'water pills' drug that can be used to treat edema conditions (i.e., excess fluid in tissues), thereby enhancing blood pressure that can damage the heart. It has been shown that the combination of both drugs may decrease the blood pressure and the incidence of hypertension.

<span>Pregnant
women are discouraged to smoke while pregnant. This can cause miscarriage
because of the toxic chemicals that cigarettes bring and are readily absorbed
by the fetus when a mother smokes. Not only will it lead to a possible
miscarriage, if the baby does survive, he/she might end up with physical
abnormalities or mental disorders. This is the reason why mothers should be
very careful about the choices they make during pregnancy because the life of a
younger being is also at stake.</span></span></span>
