An adult client exhibits an allergic reaction to an insect bite. The nurse should observe the client's skin for which finding?

Papules.

Excoriation.

Wheals.

Fissuring.

Answer and Explanation

The Correct Answer is C

A) Papules: Papules are small, raised, solid bumps on the skin that are typically less than 1 centimeter in diameter. They can be a result of various skin conditions, but they are not specifically associated with allergic reactions to insect bites.

B) Excoriation: Excoriation refers to a scratch or abrasion on the surface of the skin, often resulting from scratching due to itching. While this can occur secondary to an allergic reaction, it is not a primary characteristic of such reactions.

C) Wheals: Wheals, also known as hives or urticaria, are raised, red or skin-colored welts on the skin that often itch and can appear rapidly in response to an allergen such as an insect bite. They are a characteristic feature of allergic reactions and are caused by the release of histamine.

D) Fissuring: Fissuring refers to deep cracks or splits in the skin. While it can occur in various skin conditions, it is not a typical manifestation of an allergic reaction to an insect bite.

Correct Answer is C

Explanation

A) Paresthesia: Paresthesia refers to abnormal sensations such as tingling, pricking, or numbness, typically without an external stimulus. The client's ability to discriminate two points at specific distances on the fingertips and palms does not indicate abnormal sensations or paresthesia.

B) Rebound reaction to the needle points: A rebound reaction would involve a delayed response or heightened sensitivity following the removal of a stimulus. This test does not measure rebound reactions but rather the ability to discriminate two separate points.

C) Normal sensory finding: The ability to sense two points at a distance of 3 mm on the fingertips and 10 mm on the palms is within the normal range for two-point discrimination. The fingertips typically have a higher density of sensory receptors and thus can discriminate smaller distances between two points, whereas the palms have fewer receptors and require a greater distance to discern two points.

D) Marginal decline in sensory function: The described ability to sense two points at these specific distances does not indicate a decline in sensory function. It aligns with normal findings for a middle-aged adult.

A. White blood cell count (WBC). B. Hematocrit. C. Glucose. D. Blood urea nitrogen (BUN).

Correct Answer is B

Explanation

A) White blood cell count (WBC): While an elevated WBC count can indicate infection or inflammation, it is not directly related to melena. Melena, which is black, tarry stool, is usually an indication of gastrointestinal bleeding, specifically from the upper GI tract.

B) Hematocrit: Hematocrit is a measure of the proportion of red blood cells in the blood. Monitoring hematocrit is essential in the context of melena because gastrointestinal bleeding can lead to a decrease in red blood cells, causing anemia. Therefore, tracking hematocrit levels helps assess the severity of blood loss and the client's overall oxygen-carrying capacity.

C) Glucose: Blood glucose levels are not directly related to melena. Monitoring glucose is crucial for managing diabetes and other metabolic disorders but does not provide information about bleeding or anemia.

D) Blood urea nitrogen (BUN): While BUN levels can increase with gastrointestinal bleeding due to the breakdown of blood proteins in the gut, it is not the primary test to monitor for the effects of bleeding. Hematocrit is more directly indicative of blood loss.
