Which of the ff. does the nurse understand usually precedes rheumatic fever?

Correct Answer: B

Rationale: Rheumatic fever is an inflammatory disease that can develop as a complication of untreated or inadequately treated infections caused by group A beta-hemolytic streptococci. These bacterial infections are usually in the form of strep throat or scarlet fever. Rheumatic fever typically occurs 2-4 weeks after a streptococcal infection. The body's immune response to the streptococcal infection can lead to an autoimmune reaction, resulting in rheumatic fever. It is important to promptly diagnose and treat streptococcal infections to prevent the development of rheumatic fever.

Correct Answer: D

Rationale: Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the sacroiliac joints and the spine. It leads to progressive inflammation of the sacroiliac and costovertebral joints, which can cause pain, stiffness, and eventually lead to fusion of the affected joints. This condition is also characterized by inflammation of other joints, tendons, and ligaments, as well as extra-articular manifestations such as uveitis and cardiac involvement. Ankylosing spondylitis is more common in young males and is associated with the presence of the HLA-B27 genetic marker. It is important to diagnose and manage ankylosing spondylitis early to help prevent complications and improve quality of life for affected individuals.

Correct Answer: C

Rationale: HIV can be transmitted through specific body fluids that contain the virus. Saliva, tears, and semen do not typically contain enough HIV to transmit the virus, so they are not considered significant modes of transmission. However, blood, breast milk, and genital fluids (such as semen) are known to contain higher levels of HIV and can lead to transmission of the virus. Therefore, the nurse would include blood, breast milk, and semen as methods of transmission for HIV during the educational session.

Correct Answer: C

Rationale: A complete blood count (CBC) is a common blood test that provides important information about the types and numbers of cells in the blood, such as red blood cells, white blood cells, and platelets. The primary purpose of performing a CBC before surgery is to identify any abnormalities in the blood that could affect the patient's ability to undergo the surgical procedure safely. Abnormally low hematocrit (HCT) and hemoglobin (Hb) levels indicated by a CBC may suggest anemia, which could impact the patient's ability to tolerate surgery and anesthesia. Anemia can result in decreased oxygen delivery to tissues and organs, leading to potential complications during surgery. Therefore, identifying low HCT and Hb levels through a CBC allows healthcare providers to take appropriate measures to address and manage the condition before proceeding with surgery.

Correct Answer: D

Rationale: Thrombocytopenia is a condition characterized by a low platelet count, which can lead to impaired clot formation and increased risk of bleeding. With a low platelet count, there is an increased risk of internal bleeding and hemorrhage, which can affect vital organs such as the brain, heart, and gastrointestinal tract. Therefore, the priority nursing diagnosis for a client with thrombocytopenia receiving chemotherapy would be Ineffective tissue perfusion: Cerebral, cardiopulmonary, GI. Monitoring for signs of internal bleeding, such as changes in mental status, chest pain, and abdominal pain, is crucial to prevent potential life-threatening complications.
