A nurse is examining a skin infection on a client's lower left leg. Findings include edema, erythema, tenderness, and the client reports pain. The nurse should identify that these findings indicate which of the following?

Herpes zoster

Dermatophytosis

Contact dermatitis

Cellulitis

Answer and Explanation

The Correct Answer is D

A) Herpes zoster
This condition, also known as shingles, is characterized by a painful, blistering rash that follows a nerve path. It typically presents as grouped vesicles rather than generalized edema and erythema, making it unlikely in this case.

B) Dermatophytosis
Commonly known as ringworm, this fungal infection usually causes a scaly, ring-shaped rash. It does not typically present with significant edema or erythema as seen with cellulitis, and tenderness is less common.

C) Contact dermatitis
This allergic or irritant reaction usually causes itching, redness, and rash after contact with a substance. While it can cause erythema and pain, it is less likely to cause the significant edema and tenderness observed in cellulitis.

D) Cellulitis
Cellulitis is a bacterial skin infection characterized by edema, erythema, tenderness, and pain. These symptoms align with the nurse’s findings, indicating an inflammatory response in the deeper layers of the skin, often requiring antibiotic treatment.

Correct Answer is D

Explanation

A) A yellowed sclera:
A yellowed sclera is typically associated with jaundice, which is related to liver conditions, not acute angle-closure glaucoma. This symptom is not indicative of glaucoma.

B) Brisk pupil reactivity:
In acute angle-closure glaucoma, the pupil is often mid-dilated and sluggish to react to light due to increased intraocular pressure. Brisk pupil reactivity is not a characteristic finding in this condition.

C) Client reports a curtainlike obstruction over the visual field:
A curtainlike obstruction over the visual field is usually associated with retinal detachment, not acute angle-closure glaucoma. This description does not align with the symptoms of glaucoma.

D) Client reports seeing colored halos around lights:
Seeing colored halos around lights is a classic symptom of acute angle-closure glaucoma. This occurs due to the elevated intraocular pressure affecting the corneal surface and causing light diffraction. This manifestation is a key indicator of the condition.

A. Metabolic alkalosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic acidosis

Correct Answer is C

Explanation

A) Metabolic alkalosis: Metabolic alkalosis is characterized by a high pH and elevated bicarbonate (HCO3). In this scenario, the pH is elevated at 7.6, which supports alkalosis, but the HCO3 level is normal at 24 mEq/L. The PaCO2 is slightly low, which is not typical for metabolic alkalosis, as it would usually show an elevated HCO3 with a compensatory respiratory alkalosis.

B) Respiratory acidosis: Respiratory acidosis would present with a low pH and an elevated PaCO2. In this case, the pH is high at 7.6, indicating alkalosis, and the PaCO2 is also low at 30 mm Hg, which is inconsistent with respiratory acidosis.

C) Respiratory alkalosis: Respiratory alkalosis is indicated by a high pH with a low PaCO2. Here, the pH is elevated at 7.6, and the PaCO2 is decreased at 30 mm Hg, which fits the profile of respiratory alkalosis. The normal HCO3 level suggests that the bicarbonate is not compensating, supporting a primary respiratory alkalosis.

D) Metabolic acidosis: Metabolic acidosis is characterized by a low pH and a low HCO3. In this scenario, the pH is elevated at 7.6, and the HCO3 level is normal at 24 mEq/L, which does not align with metabolic acidosis. The PaCO2 is also low, which is not typical for metabolic acidosis, as it would usually have a normal or high PaCO2.
