Levothyroxine for hypothyroidism
Phenytoin for seizure disorder
Magnesium oxide for constipation
Ferrous sulfate for chronic anemia
The Correct Answer is B
A. Levothyroxine is a thyroid hormone replacement medication commonly used to treat hypothyroidism. It is not associated with teratogenic effects when used appropriately.
B. Phenytoin is an anticonvulsant medication that is known to be teratogenic, especially when used during the first trimester of pregnancy. It is associated with an increased risk of congenital malformations, such as cleft palate and heart defects, in infants born to mothers who take the medication during pregnancy.

Correct Answer is A
Explanation
- Rationale for A: Following simple instructions indicates that the client is cooperative and may no longer pose a threat to themselves or others, which is a primary consideration for the removal of restraints. It shows the client's ability to understand and comply with directions, suggesting they are in a calmer state of mind. This behavioral change is a positive sign of regained control, making it safe to consider restraint removal.
- Rationale for B: While an apology may show remorse, it does not necessarily indicate that the client has calmed down or that they can safely interact without the restraints. Apologies can be driven by various motivations and do not reliably demonstrate a change in the risk of aggression.
- Rationale for C: A request to have restraints removed is not sufficient evidence of reduced risk. The client's desire to be unrestrained does not equate to a behavioral change that would justify removal, as it does not assess the client's current mental state or potential for aggression.
- Rationale for D: Maintaining eye contact is a positive social behavior but does not directly correlate with the client's potential for aggression or their ability to be safely managed without restraints. It is not a definitive indicator of the client's readiness to have restraints removed.
Correct Answer is A
Explanation
A.
A. Profuse milky white discharge: Bacterial vaginosis is characterized by a fishy odor and a thin, homogeneous, grayish-white discharge, not milky white. However, this option is the most closely associated with bacterial vaginosis among the choices provided.
B. Frequency and dysuria: These symptoms are more indicative of urinary tract infection rather than bacterial vaginosis.
C. Low-grade fever: Fever is not typically associated with bacterial vaginosis unless there is a secondary infection present.
D. Hematuria: Hematuria, or blood in the urine, is not a typical symptom of bacterial vaginosis.
