Correct Answer is A

Explanation

a. Three to seven days after menses stops: Performing BSE a few days after menstruation allows the breasts to return to a more baseline state, reducing the influence of hormonal changes on

breast tissue.

b. On the same day every month: Hormonal changes during the menstrual cycle can affect breast tissue, and performing BSE on the same day every month may not provide consistent conditions for examination.

c. Prior to the beginning of menses: Hormonal changes before menstruation can lead to breast tenderness and changes, potentially affecting the accuracy of the examination.

d. On the second day of menstruation: Hormonal changes and potential breast tenderness during the early days of menstruation may not be the optimal time for BSE.

A. Request an order for an antiemetic. B. Request a dietary consult. C. Check the client’s vital signs. D. Suggest that the client rests before eating the meal.

Correct Answer is C

Explanation

A. Request an order for an antiemetic - Checking vital signs is the priority before administering any medication. Antiemetics may be considered later, but the nurse needs to assess the client's overall condition first.

B. Request a dietary consult - Assessing vital signs comes before consulting for dietary issues.

The priority is to determine the client's immediate physiological status.

C. Check the client’s vital signs - This is the correct first action as it helps to evaluate the client's cardiovascular status, especially considering the potential toxicity of digoxin in the setting of

nausea and refusal of breakfast.

D. Suggest that the client rests before eating the meal - While rest may be beneficial, assessing vital signs takes precedence to rule out any acute cardiovascular compromise.
