A nurse document that a client has a normal pupillary light reflex. The nurse should recognize that this reflex indicates which of the following?

The eye focuses the image in the center of the pupil

Constriction both pupils occurs in response to bright light

The eye focuses the light on the sclera

Dilation of both pupils occurs in response to bright light

Answer and Explanation

The Correct Answer is B

A) The eye focuses the image in the center of the pupil:
This option describes the accommodation reflex, not the pupillary light reflex. The accommodation reflex involves the focusing of the eye to bring an image to the center of the retina, but it does not relate to the constriction of the pupils in response to light. Therefore, it is not the correct answer for describing the pupillary light reflex.

B) Constriction of both pupils occurs in response to bright light:
This is the correct description of the pupillary light reflex. When light is shined into one eye, the normal response is for both pupils (direct and consensual response) to constrict. The pupillary light reflex tests the integrity of the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III), which control the constriction of the pupil in response to light. A normal pupillary light reflex is characterized by the constriction of both pupils when exposed to light.

C) The eye focuses the light on the sclera:
This statement is inaccurate. The sclera is the white part of the eye, and light is focused on the retina (specifically the fovea) for proper vision. This does not relate to the pupillary light reflex, which specifically refers to the constriction of the pupils in response to light.

D) Dilation of both pupils occurs in response to bright light:
This is incorrect. Dilation of the pupils occurs in low light conditions as part of the pupillary dilation reflex (also called the "dark reflex") to allow more light into the eye. However, in response to bright light, the pupils constrict, not dilate. The constriction of the pupils in bright light is the primary characteristic of a normal pupillary light reflex.

Correct Answer is ["B","C","E"]

Explanation

A) Client's oral temperature is 38.4°C (101.2°F):
This is objective data, as it is a measurable, observable finding obtained through direct assessment (in this case, using a thermometer). Objective data are facts or measurements that can be verified or observed by the healthcare provider.

B) Client reports the rash on their back is itchy:
This is subjective data, as it is based on the client's personal experience and report. The feeling of itchiness cannot be directly measured or observed by the nurse; it is something the client experiences and describes. Subjective data include symptoms, sensations, or feelings reported by the client.

C) Client reports nausea following administration of pain medication:
This is subjective data. Nausea is a symptom that the client reports experiencing, which cannot be objectively measured or directly observed by the nurse. It is based on the client's perception and report, making it subjective.

D) Client has a vesicular rash on their upper back:
This is objective data. The rash is something the nurse can observe and describe. Objective data include observable facts, such as physical exam findings, lab results, or diagnostic test results.

E) Client reports dull, aching pain in lower right calf:
This is subjective data, as pain is a sensation that the client experiences and describes. The intensity, location, and type of pain (dull, aching) are subjective experiences that only the client can report.

A. The partner places the client's arm above the level of the client's heart B. The partner centres the cuff bladder over the client's brachial artery C. The partner wraps the blood pressure cuff around the client's using firm pressure D. The partner checks the instrument gauge to ensure the reading starts at zero

Correct Answer is A

Explanation

A) The partner places the client's arm above the level of the client's heart:
This action indicates that further instruction is needed. For an accurate blood pressure reading, the arm should be at heart level (approximately at the level of the fourth intercostal space) when taking the measurement. If the arm is placed above the heart, it can result in a falsely low reading. If the arm is positioned below the heart, it can lead to a falsely high reading. The position of the arm is crucial for obtaining an accurate blood pressure measurement.

B) The partner centres the cuff bladder over the client's brachial artery:
This is the correct technique. The cuff bladder should be centered over the brachial artery for accurate readings. Proper cuff placement ensures the best possible measurement and avoids errors in reading due to misplacement.

C) The partner wraps the blood pressure cuff around the client's arm using firm pressure:
This is also correct. The cuff should be wrapped snugly around the upper arm with firm pressure to ensure that it fits properly. If the cuff is too loose or too tight, it may give inaccurate readings. However, it should never be excessively tight.

D) The partner checks the instrument gauge to ensure the reading starts at zero:
This is a correct action. Before using a blood pressure cuff, it is important to check that the gauge starts at zero when the cuff is deflated. This ensures the manometer is calibrated properly and provides accurate readings. If the gauge does not start at zero, it should be recalibrated or replaced.
