The nurse is discussing the blood flow pattern of the heart. The nurse should recognize which of the following as the accurate blood flow pattern of the heart?

A. The best time to perform a BSE is 4 to 7 days after the first day of the menstrual period:

This statement is correct. Performing BSE a few days after the menstrual period ensures that the breasts are less likely to be swollen or tender, which can make it easier to detect any unusual changes.

B. If she suspects that she is pregnant, then the woman should not perform a BSE until her baby is born:

This statement is incorrect. Pregnant women can still perform breast self-examinations. In fact, it's important for pregnant women to be aware of any changes in their breasts.

C. The best time to perform BSE is in the middle of the menstrual cycle:

This statement is not as accurate as the first choice. While it's true that performing BSE a few days after the menstrual period can be easier due to reduced breast tenderness, it doesn't necessarily mean the middle of the menstrual cycle for every woman. The timing can vary based on an individual's menstrual cycle.

D. The woman needs to perform BSE only bimonthly unless she has fibrocystic breast tissue:

This statement is incorrect. Regular monthly breast self-examinations are recommended for all women, regardless of whether they have fibrocystic breast tissue or not. Detecting changes early is crucial for breast health.

A. When part of the lung is obstructed or collapsed: This statement is accurate. Unequal chest expansion can occur when part of the lung is obstructed or collapsed, preventing the affected area from expanding normally during inhalation.

B. When bulging of the intercostal spaces is present: This statement is not accurate. Unequal chest expansion typically refers to decreased expansion on one side, not bulging of intercostal spaces.

C. In an obese patient: This statement is not accurate. Obesity can affect breathing patterns and lung function, but it is not the primary cause of unequal chest expansion.

D. When accessory muscles are used to augment respiratory effort: This statement is not accurate. The use of accessory muscles to augment respiratory effort can be a sign of respiratory distress, but it doesn't directly cause unequal chest expansion. Unequal expansion is more indicative of specific lung conditions or issues with lung mechanics.
