A nurse documents that the client has a normal pupillary light reflex. The nurse should recognize that this reflex indicates which of the following?
The eyes converge to focus on the light.
The eye focuses the image in the center of the pupil.
Dilation of both pupils occurs in response to bright light.
Constriction of both pupils occurs in response to bright light.
The Correct Answer is D
A. The eyes converge to focus on the light.
This statement refers to the convergence reflex, where both eyes move medially (towards each other) to maintain single binocular vision when focusing on a near object. It is not related to the pupillary light reflex, which involves changes in pupil size in response to light.
B. The eye focuses the image in the center of the pupil.
This choice does not accurately describe the pupillary light reflex. The pupillary light reflex involves constriction of the pupil in response to light, not focusing an image in the center of the pupil.
C. Dilation of both pupils occurs in response to bright light.
This statement is incorrect. In response to bright light, the pupils should constrict, not dilate. Dilation of pupils in bright light could indicate an abnormal response, such as in cases of certain neurological conditions or drug use.
D. Constriction of both pupils occurs in response to bright light.
This choice is correct. In the pupillary light reflex, both pupils constrict when exposed to bright light. This response is a protective mechanism to prevent excessive light from entering the eyes, ensuring optimal visual acuity.

Correct Answer is A
Explanation
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.
Correct Answer is A
Explanation
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.
