COT Visual Assessment 5

Question 1

During a visual assessment of a patient's skin, you notice a lesion that is flat, non-palpable, and less than 1 cm in diameter with a distinct color change from surrounding skin. How would you correctly document this finding?

Accepted Answer

Macule

Answer

A macule is a flat, non-palpable skin lesion less than 1 cm in diameter that differs in color from surrounding skin. It cannot be felt upon palpation, distinguishing it from a papule (raised) or vesicle (fluid-filled). A plaque is larger than 1 cm and elevated.

Question 2

When performing a visual assessment of a patient's respiratory pattern, you observe that the patient's breathing gradually increases in depth and rate, then decreases, followed by a period of apnea. This pattern repeats cyclically. What is this breathing pattern called?

Accepted Answer

Cheyne-Stokes respirations

Answer

Cheyne-Stokes respirations are characterized by a cyclic pattern of gradually increasing then decreasing depth and rate of breathing, followed by a period of apnea. This pattern is often associated with heart failure, increased intracranial pressure, or neurological injury. Biot's has irregular clusters with sudden apnea; Kussmaul is deep and labored without the cyclic variation.

Question 3

A COT is performing a visual assessment of a patient's eye and notices that the sclera appears yellow. Which term correctly describes this finding and what does it suggest?

Accepted Answer

Icterus — indicating elevated bilirubin levels

Answer

Yellow discoloration of the sclera is called icterus (or jaundice) and is caused by elevated bilirubin levels in the blood, which can indicate liver disease, bile duct obstruction, or hemolytic conditions. Pallor refers to paleness, cyanosis is a bluish discoloration indicating poor oxygenation, and erythema is redness from inflammation.

Question 4

While visually assessing a patient's abdomen, you observe a bluish discoloration around the umbilicus. This finding is known as which sign, and what condition is it classically associated with?

Accepted Answer

Cullen's sign — intraperitoneal or retroperitoneal hemorrhage

Answer

Cullen's sign is periumbilical bruising or bluish discoloration around the navel caused by subcutaneous hemorrhage tracking from intraperitoneal or retroperitoneal bleeding. It is classically associated with ruptured ectopic pregnancy or acute hemorrhagic pancreatitis. Grey Turner's sign involves flank discoloration. McBurney's and Rovsing's signs are assessed by palpation, not visual observation.

Question 5

During a visual assessment, a COT observes that a patient has a barrel-chest deformity with an increased anterior-posterior diameter. The patient also appears to be using pursed-lip breathing. Which underlying condition is most consistent with these combined visual findings?

Accepted Answer

Chronic obstructive pulmonary disease (COPD)

Answer

Barrel chest (increased AP diameter due to chronic air trapping) combined with pursed-lip breathing (to maintain positive end-expiratory pressure and slow expiration) are classic visual signs of COPD, particularly emphysema. These adaptations develop over time due to chronic hyperinflation. Pneumonia and pulmonary embolism are acute conditions without these chronic structural changes, and pleural effusion presents differently.
