Which of the following is a potential adverse reaction to silver sulfadiazine in burn victims?

Improved wound healing

Allergic reaction in patients with sulfa allergies

Delayed wound healing

Increased risk of infection

Answer and Explanation

The Correct Answer is B

A. Improved wound healing:

While silver sulfadiazine is used to promote wound healing by preventing and treating infections in burn victims, this is not an adverse reaction. This is an intended therapeutic effect of the medication.

B. Allergic reaction in patients with sulfa allergies:

Silver sulfadiazine contains sulfa, and patients who have a sulfa allergy may experience an allergic reaction. This can range from mild skin rashes to severe systemic reactions and is considered a significant adverse reaction.

C. Delayed wound healing:

Silver sulfadiazine is generally used to promote wound healing by preventing bacterial infections. Delayed wound healing is not a common adverse reaction but may occur in some cases due to other underlying factors or if the medication is not effective against certain bacteria.

D. Increased risk of infection:

The primary purpose of silver sulfadiazine is to reduce the risk of infection in burn wounds. An increased risk of infection would indicate a failure of the medication, not an adverse reaction. The correct potential adverse reaction is an allergic response in patients with a known sulfa allergy.

Correct Answer is C

Explanation

A) Blockage of the tear ducts causing excessive tearing:

Blockage of tear ducts (dacryostenosis) results in excessive tearing (epiphora) due to inadequate drainage of tears into the nasal cavity. It does not directly contribute to glaucoma, which primarily involves increased intraocular pressure (IOP) and optic nerve damage.

B) Inflammation of the cornea resulting in blurry vision:

Corneal inflammation (keratitis) can cause blurry vision, pain, and sensitivity to light, but it is not the primary pathophysiology of glaucoma. Glaucoma primarily involves damage to the optic nerve due to elevated IOP.

C) Increased intraocular pressure (IOP) leading to optic nerve damage:

Glaucoma is characterized by elevated IOP, which puts pressure on the optic nerve and can lead to progressive damage and vision loss if untreated. This is the primary pathophysiological process in most types of glaucoma.

D) Degeneration of the lens leading to cataracts:

Cataracts involve the clouding of the lens of the eye, leading to visual impairment. While cataracts are a common condition in older adults, they are not directly related to the pathophysiology of glaucoma, which primarily involves elevated IOP and optic nerve damage.

A. Snellen chart B. Penlight C. Magazine D. Ophthalmoscope

Correct Answer is C

Explanation

A) Snellen chart:

The Snellen chart is used to assess distance vision, not near vision. It consists of letters or symbols arranged in rows, with the client typically asked to read from a specific distance to test visual acuity.

B) Penlight:

A penlight is primarily used to assess pupillary reactions and near vision tasks such as accommodation. It helps examine how the pupils respond to light and how well the eyes focus on near objects.

C) Magazine:

A magazine or similar reading material is commonly used to assess near vision. Clients are asked to read the text at a comfortable distance, evaluating their ability to focus on close-up objects and the clarity of their vision.

D) Ophthalmoscope:

An ophthalmoscope is used to examine the interior structures of the eye, such as the retina and optic nerve head. It is not used for assessing near vision but rather for diagnosing conditions affecting the eye's internal structures.
