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
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 C
Explanation
A. Assessing the degree of upper body vasculature may provide some information, but it does not directly address the client's current symptoms or vital status.
B. Measuring arm circumference and evaluating the degree of edema are important for understanding the extent of swelling but do not assess the client’s hemodynamic stability or respiratory status.
C. Blood pressure and heart rate are critical assessments in this scenario, especially considering the client’s dyspnea and upper body edema. Changes in these vital signs can indicate potential respiratory distress, compromised cardiac function, or anaphylaxis, which requires immediate intervention.
D. While assessing peripheral sensation and movement is important for overall neurological function, it is not a priority in this context compared to assessing vital signs that can directly affect the client’s stability.
Correct Answer is C
Explanation
A. This statement may not be ideal; smaller, more frequent meals can help manage appetite and energy levels better than three large meals, especially for cancer patients who may experience fatigue or nausea.
B. A flat lying position can hinder lung expansion; a more elevated position is generally recommended to facilitate breathing.
C. This statement shows understanding of the need to manage energy levels and not overexert oneself, which is crucial for maintaining stamina during treatment.
D. Pain management typically requires more frequent dosing rather than a once-a-day regimen, depending on the severity of the pain.
