The nurse prepares to assess the patient's cranial nerves. Which tool is necessary to assess cranial nerve (CN) III (oculomotor)?

Otoscope

Penlight

Cotton ball

Lavender

Answer and Explanation

The Correct Answer is B

A. An otoscope is used to examine the ear canal and tympanic membrane, not to assess cranial nerve III. This tool is more relevant for assessing cranial nerve VIII (vestibulocochlear), which is responsible for hearing and balance.
B. A penlight is used to assess CN III (oculomotor) by evaluating the pupil's response to light and the ability to move the eye. This nerve controls most of the eye's movements, including constriction of the pupil in response to light.
C. A cotton ball is used to test the sensory function of cranial nerve V (trigeminal), which is responsible for facial sensation. It is not used for assessing CN III.
D. Lavender or other scents may be used to test CN I (olfactory), responsible for the sense of smell, but it is not related to CN III, which governs eye movements and pupil reactions.

Correct Answer is B

Explanation

A. Increasing fiber intake is generally beneficial for digestive health but alone may not address the client's specific concern regarding colon cancer risk, making this advice too narrow.
B. Discussing family history and early screening options with a primary care provider is crucial, as it can lead to earlier detection and intervention, especially given the family history of colon cancer.
C. The CEA blood test is not routinely used for cancer screening; it is primarily used to monitor treatment response or recurrence, not for predicting the development of cancer.
D. Waiting until the age of 60 to be concerned about colon cancer is not advisable, especially with a family history; proactive discussions about screening should begin earlier based on risk factors.

A. A profound feeling of tiredness B. Renal impairment C. Expectoration of frothy sputum D. Development of bone marrow suppression

Correct Answer is A

Explanation

A. A profound feeling of tiredness is a common side effect of radiation therapy due to fatigue caused by the treatment itself and the body's response to cancer.
B. Renal impairment is not a typical direct side effect of radiation therapy for esophageal cancer; it is more commonly associated with treatments targeting the kidneys or systemic therapies.
C. Expectoration of frothy sputum may indicate pulmonary issues or fluid overload but is not a common side effect specifically related to radiation therapy for esophageal cancer.
D. Development of bone marrow suppression is possible but less common specifically with radiation therapy compared to chemotherapy, which is more directly associated with this side effect.
