The nurse working in an ophthalmology clinic is preparing to assess a patient's near vision. Which piece of equipment would the nurse use for this assessment?
Ophthalmoscope
Snellen Chart
Magazine
Penlight
The Correct Answer is B
Choice A Reason:
An ophthalmoscope is primarily used for examining the interior structures of the eye, such as the retina, and is not typically used for assessing near vision. It provides a view of the fundus of the eye, which is essential for diagnosing various eye conditions but does not directly assess a patient's reading or close-up vision.
Choice B Reason:
The Snellen Chart is traditionally used to measure distance visual acuity and would not be the first choice for assessing near vision. However, there are versions of the Snellen Chart or similar charts designed for near vision assessment, typically held at a reading distance of about 14 inches from the patient. These charts have rows of letters or symbols that decrease in size and are used to determine the smallest print size a person can read.
Choice C Reason:
A magazine can be a practical tool for assessing near vision informally, as it contains various sizes of print and is a good representation of everyday reading material. The nurse can ask the patient to read a specific paragraph to observe their ability to see and comprehend text at a close distance.
Choice D Reason:
A penlight is not used for assessing near vision. It is typically used to assess the pupillary light reflex or to illuminate specific areas of the eye during an examination. The penlight helps to evaluate the response of the pupils to light but does not measure the patient's ability to read or see objects up close.

Correct Answer is C
Explanation
Choice a reason:
Rhonchi are coarse, rattling respiratory sounds somewhat like snoring, usually caused by obstruction or secretion in the larger airways. They are not considered normal breath sounds and are typically heard in conditions such as chronic bronchitis.
Choice b reason:
Crackles are the sounds you will hear in a lung field that has fluid in the small airways. These sounds are commonly heard in patients with pneumonia, heart failure, and restrictive pulmonary diseases. They are not normal breath sounds.
Choice c reason:
Bronchovesicular sounds are normal breath sounds heard over the main bronchus area and over the upper right posterior lung field. They have a medium pitch and intensity and are heard on both inspiration and expiration. In a healthy individual, these sounds are expected to be heard in the 1st and 2nd intercostal spaces near the sternal body.
Choice d reason:
Tracheal breath sounds are harsh, high-pitched sounds heard when auscultating over the trachea in the neck. They are not normally heard over the intercostal spaces of the chest wall.
Correct Answer is B
Explanation
Choice A reason:
Diabetes mellitus is not typically associated with pitting edema unless it has led to a comorbid condition such as heart failure or kidney disease. Pitting edema is more commonly associated with fluid retention due to the body's inability to manage fluid balance, which is not a direct consequence of diabetes mellitus itself.
Choice B reason:
Liver disease, particularly cirrhosis, can lead to pitting edema. The liver's inability to produce albumin, a protein that helps maintain oncotic pressure in the blood vessels, and portal hypertension, which is an increase in the blood pressure within the portal vein system, can both contribute to the development of pitting edema.
Choice C reason:
End-stage renal disease can also cause pitting edema due to the kidneys' inability to excrete excess fluid. However, the edema associated with renal disease is often more generalized and not limited to the lower extremities.
Choice D reason:
Colon cancer is not typically associated with pitting edema unless it has metastasized and caused secondary complications that affect the liver or the heart. Pitting edema is not a direct symptom of colon cancer itself.
