In which disease process should a nurse expect to see a patient with the presence of pitting edema?
Diabetes mellitus
Liver disease
End-stage renal disease
Colon cancer
The Correct Answer is B
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.

Correct Answer is B
Explanation
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:
Palpitations are typically associated with hyperthyroidism, not hypothyroidism. They occur due to an excess of thyroid hormones, which can overstimulate the heart, leading to increased heart rate and palpitations. In hypothyroidism, the heart rate is usually slower, and palpitations are less common.
Choice B Reason:
Diaphoresis, or excessive sweating, is also more commonly associated with hyperthyroidism. In hypothyroidism, the metabolism is slowed down, which reduces the tendency for increased sweating. Patients with hypothyroidism may actually have less sweating than normal.
Choice C Reason:
Weight gain is a common symptom of hypothyroidism. Due to the decreased metabolic rate caused by low levels of thyroid hormones, the body burns fewer calories, which can lead to weight gain. This is one of the hallmark signs of hypothyroidism and is often one of the first symptoms patients notice.
Choice D Reason:
Exophthalmos, the protrusion of the eyes, is a symptom associated with Graves' disease, a form of hyperthyroidism. It is not a symptom of hypothyroidism. In hypothyroidism, any eye changes are usually related to puffiness or edema around the eyes, not the bulging of the eyes themselves.
