A nurse is doing prenatal counseling with a client and is asked about the importance of folic acid (B9) during pregnancy. Based on the nurse's knowledge, what should be the nurse's response?

Folic acid is known to lower blood glucose in diabetic patients

Folic acid prevents neural tube defects in the developing fetus

Folic acid will prevent migraine headaches in pregnant women

Answer and Explanation

The Correct Answer is B

A. Folic acid does not specifically lower blood glucose; rather, it is primarily involved in DNA synthesis and cell division.
B. Folic acid is essential during pregnancy as it significantly reduces the risk of neural tube defects, such as spina bifida and anencephaly, in the developing fetus, making it a critical nutrient for pregnant women.
C. Folic acid does not prevent celiac disease; rather, celiac disease is an autoimmune disorder related to gluten intake.
D. While some studies suggest that folic acid may have a role in reducing the frequency of migraines, it is not a primary indication during pregnancy.

Correct Answer is C

Explanation

A. Hydrochlorothiazide is a thiazide diuretic that can be used for hypertension and edema but is not specifically indicated for open-angle glaucoma.
B. Furosemide is a loop diuretic used primarily for fluid overload conditions and does not have a specific role in the treatment of open-angle glaucoma.
C. Acetazolamide is a carbonic anhydrase inhibitor that reduces aqueous humor production and is specifically used to lower intraocular pressure in clients with open-angle glaucoma.
D. Spironolactone is a potassium-sparing diuretic used mainly for conditions like heart failure and hypertension, and it is not indicated for the treatment of open-angle glaucoma.

A. "Depending on the level of your PT/INR, the clot will begin to dissolve." B. "It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level." C. "Heparin does not dissolve clots. It stops new clots from forming." D. "After the first dose, the clot will begin to dissolve."

Correct Answer is C

Explanation

A. PT/INR is not the appropriate measure for heparin therapy, as heparin is monitored using activated partial thromboplastin time (aPTT). This response could mislead the client regarding treatment expectations.
B. While it may take time to reach therapeutic levels, this statement doesn't clarify that heparin is not a clot-dissolving agent.
C. Heparin prevents the extension of existing clots and the formation of new clots but does not actively dissolve clots already present.
D. This statement incorrectly suggests that immediate effects are seen, which is not the case as heparin's action involves prevention rather than dissolution.
