A nurse in an allergy clinic is caring for a client who has a history of seasonal allergy symptoms. The client had a radioallergosorbent test (RAST) completed on a previous visit. The nurse should recognize that an elevation in which of the following immunoglobulins indicates a positive result?

Immunoglobulin E (IgE)

Immunoglobulin M (IgM)

Immunoglobulin A (IgA)

Immunoglobulin G (IgG)

Answer and Explanation

The Correct Answer is A

Choice A reason: Immunoglobulin E (IgE) is associated with allergic reactions. A RAST test measures the level of allergen specific IgE antibodies in the blood. An elevation in IgE indicates sensitization to a particular allergen and a positive result for the allergy.

Choice B reason: Immunoglobulin M (IgM) is usually the first antibody produced by the immune system when it detects an infection. It is not typically associated with the detection of allergies.

Choice C reason: Immunoglobulin A (IgA) plays a critical role in mucosal immunity and is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and the gastrointestinal tract, but it is not used as an indicator in RAST testing for allergies.

Choice D reason: Immunoglobulin G (IgG) is the most abundant type of antibody and is involved in the recognition and removal of pathogens. It is not specific to allergic response detection in RAST testing.

Correct Answer is ["A","B","D"]

Explanation

Choice A reason: Enlarged distal extremities are a classic sign of acromegaly due to the overproduction of growth hormone, which affects the growth plates in the bones.

Choice B reason: Coarse facial features, including a protruding jaw and brow, enlarged nose, and thickened lips, are common in acromegaly due to the excessive growth of facial bones and soft tissues.

Choice C reason: Loss of color discrimination is not typically associated with acromegaly. This symptom may be related to other conditions affecting the optic nerve or the brain.

Choice D reason: Hepatomegaly, or an enlarged liver, can occur in acromegaly as a result of increased growth factor effects on the liver.

Choice E reason: Moon face is associated with conditions that lead to corticosteroid excess, such as Cushing's syndrome, but can also appear in acromegaly due to soft tissue swelling.

A. Serum creatinine 1.8 mg/dL B. Magnesium 2.0 mEq/L C. Blood urea nitrogen (BUN) 20 mg/dL D. Serum osmolality 290 mOsm/kg H2O

Correct Answer is A

Explanation

Choice A reason: Serum creatinine is a waste product from the normal breakdown of muscle tissue. A level of 1.8 mg/dL is higher than the normal range (0.61.2 mg/dL for females), indicating impaired kidney function and an increased risk of AKI.

Choice B reason: A magnesium level of 2.0 mEq/L is within the normal range (1.72.2 mEq/L) and does not typically indicate an increased risk of AKI.

Choice C reason: A BUN level of 20 mg/dL is within the normal range (720 mg/dL) and does not suggest an increased risk of AKI by itself.

Choice D reason: A serum osmolality of 290 mOsm/kg H2O is within the normal range (275295 mOsm/kg H2O) and does not indicate an increased risk of AKI.
