During a skin assessment, the nurse notes a 1.5 cm irregularly shaped dark lesion with uneven borders and color variation. What should be the nurse's priority action?

Rationale:
A. Glaucoma is characterized by increased intraocular pressure that can lead to optic nerve damage and gradual peripheral vision loss. The lens remains clear, so a cloudy or opaque lens is not typical of glaucoma.

B. This condition affects the macula, the central portion of the retina, leading to loss of central vision. The lens is not affected, so cloudy or opaque areas over the lens do not occur with macular degeneration.

C. This is a complication of diabetes that damages the retinal blood vessels, causing hemorrhages, exudates, and vision loss. It affects the retina, not the lens, so a cloudy or opaque lens is not a characteristic finding.

D. Cataracts involve clouding of the lens, which obstructs light from passing clearly to the retina. This cloudiness is the hallmark sign of cataracts and can lead to blurred vision, glare, and difficulty seeing in low light. The description of a cloudy, opaque area over the lens directly indicates a cataract.

Rationale:

A. This term describes a slower-than-normal respiratory rate. In adults, bradypnea is usually defined as fewer than 12 breaths per minute. Bradypnea can be caused by factors such as drug overdose (especially opioids or sedatives), head injury affecting the respiratory center, hypothyroidism, or severe hypothermia. In this scenario, the patient’s respiratory rate is 28 breaths per minute, which is well above the normal adult range of 12–20 breaths per minute. Therefore, bradypnea is incorrect.

B. Tachycardia refers to an elevated heart rate, generally defined as a heart rate greater than 100 beats per minute in adults. It is important not to confuse heart rate terminology with respiratory rate terminology. Since this scenario only provides information about the patient’s breathing, not heart rate, tachycardia is not applicable.

C. Tachypnea is an abnormally rapid respiratory rate, typically defined as greater than 20 breaths per minute in adults. The patient’s rate of 28 breaths per minute falls clearly into this category. Tachypnea can result from a variety of conditions, including fever, anxiety, pain, hypoxia, pulmonary diseases (like asthma, pneumonia, or pulmonary embolism), metabolic acidosis (e.g., diabetic ketoacidosis), or heart failure. Accurately documenting tachypnea is essential, as it is an early indicator of respiratory distress or systemic illness and can guide further assessment and interventions, such as oxygen therapy, monitoring oxygen saturation, or evaluating for underlying causes.

D. Apnea is the complete absence of respirations. It may occur in conditions such as respiratory arrest, severe sleep apnea, or central nervous system depression. Since the patient is actively breathing at a rate of 28, apnea is clearly incorrect.
