Antibodies are made of which of the following types of substances?

Correct Answer: B

Rationale: Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of pathogens like bacteria, viruses, and other foreign substances. These proteins are specifically designed to recognize and bind to antigens, which are molecules that the immune system identifies as foreign or harmful. Antibodies play a crucial role in the immune response by marking pathogens for destruction by other immune cells and signaling the immune system to attack the invaders. Therefore, antibodies are primarily made up of proteins.

Correct Answer: B

Rationale: AIDS related distal sensory polyneuropathy (DSP) is a common neurological complication in individuals living with HIV or AIDS. One of the hallmark symptoms associated with DSP is the presence of abnormal sensations such as burning pain, tingling, numbness, and hypersensitivity in the distal extremities. These abnormal sensations are typically described as a feeling of pins and needles or electric shocks. Patients may also experience a loss of proprioception, leading to difficulties in coordination and balance. Staggering gait and muscle incoordination (choice A) may be seen in patients with advanced stages of DSP, but the primary symptom associated with the condition is the presence of abnormal sensory perceptions. Delusional thinking (choice C) and incontinence (choice D) are not typical symptoms of AIDS related distal sensory polyneuropathy.

Correct Answer: A

Rationale: Basophils are a type of white blood cell that are involved in releasing histamine during an allergic reaction. When an allergen triggers the immune system, basophils release histamine and other chemical mediators. Histamine plays a key role in the inflammatory response associated with allergies, leading to symptoms such as itching, hives, and swelling. Basophils are known for their role in allergic reactions and are an important part of the body's defense against parasites and in the inflammatory response.

Correct Answer: C

Rationale: Osteoporosis is the most likely adverse effect of long-term corticosteroid therapy responsible for the severe back pain experienced by the client with systemic lupus erythematosus (SLE). Corticosteroids such as prednisone can lead to bone resorption and calcium loss, resulting in weakened bones and increased risk of fractures. Back pain in this case could be a sign of vertebral compression fractures due to osteoporosis induced by prolonged corticosteroid use. It is important for healthcare providers to monitor bone health in patients on long-term corticosteroid therapy and consider strategies to prevent or manage osteoporosis.

Correct Answer: C

Rationale: Iron-deficiency anemia is a common type of anemia characterized by a lack of iron in the body, which leads to decreased production of red blood cells containing hemoglobin. The assessment findings characteristic of iron-deficiency anemia include dyspnea (shortness of breath) due to decreased oxygen-carrying capacity of the blood, tachycardia (rapid heart rate) as the body tries to compensate for decreased oxygen delivery, and pallor (pale skin and mucous membranes) due to reduced red blood cell production. These symptoms result from insufficient iron levels affecting the body's ability to produce an adequate number of healthy red blood cells. Night sweats, weight loss, and diarrhea are not typically associated with iron-deficiency anemia. Nausea, vomiting, anorexia, itching, rash, and jaundice are also not primary manifestations of iron-deficiency an
