Adult Health Nursing Quizlet Final

Correct Answer: A

Rationale: Selective IgA deficiency is a primary immunodeficiency disorder characterized by low or absent levels of immunoglobulin A (IgA) in the blood. Since IgA plays a crucial role in mucosal immunity and defense against pathogens at mucosal surfaces, individuals with this deficiency are more susceptible to recurrent bacterial infections, particularly of the respiratory and gastrointestinal tracts. In contrast, severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder affecting T and B lymphocytes, chronic granulomatous disease (CGD) is a disorder of phagocytes, and autoimmune hemolytic anemia is an autoimmune disease involving red blood cells, none of which are directly associated with selective IgA deficiency.

Correct Answer: C

Rationale: The scenario described is suggestive of a meniscus injury. A twisting injury during sports activity leading to acute knee pain and swelling, accompanied by joint effusion and tenderness along the joint line, is commonly associated with meniscus tears. The meniscus is a C-shaped cartilage structure located between the femur and tibia in the knee joint, providing cushioning and stability. The symptoms of a meniscus tear typically include pain, swelling, joint line tenderness, and sometimes mechanical symptoms like locking or clicking. Treatment may involve rest, physical therapy, or in some cases, surgery to repair or remove the torn meniscus.

Correct Answer: C

Rationale: Periodontitis is the dental condition characterized by inflammation and destruction of the supporting structures of the teeth, including the gingiva (gums), periodontal ligament, and alveolar bone. It is usually caused by untreated gingivitis, where plaque buildup along the gumline leads to bacterial infection and inflammation, resulting in destruction of the tissues that support the teeth. If left untreated, periodontitis can lead to tooth loss and other complications. Gingivitis, on the other hand, is inflammation of the gums without involvement of the supporting structures, while dental caries refer to tooth decay or cavities in the enamel. Dental abscess is a localized collection of pus caused by a bacterial infection.

Correct Answer: A

Rationale: Providing education on strategies for initiating and maintaining milk supply should be prioritized to support successful breastfeeding in this situation. Preterm infants can benefit significantly from breast milk due to its unique composition that supports their growth and development. Educating the client on techniques such as pumping to establish and maintain milk supply, proper latching techniques, and understanding the benefits of breastfeeding for preterm infants can help alleviate her concerns and increase her confidence in breastfeeding her premature infant. Additionally, promoting skin-to-skin contact and frequent feedings can also help stimulate milk production and foster bonding between the mother and infant. Encouraging and supporting the client with evidence-based information will be crucial in promoting successful breastfeeding outcomes for the preterm infant.

Correct Answer: B

Rationale: When managing a conscious patient with a severe nosebleed (epistaxis), the appropriate intervention is to have the patient sit upright and lean slightly forward to prevent blood from flowing into the throat and causing choking or swallowing. Pinching the soft part of the nose just below the bony part can help apply pressure to the bleeding vessel and stop the bleeding. This maneuver also helps compress the blood vessels in the nose, promoting clot formation and stopping the bleeding. It is important not to tilt the head back as this can cause blood to flow into the throat and potentially lead to swallowing, choking, or aspiration. Packing the nose with cotton gauze should be done by medical professionals if the bleeding does not stop with direct pressure. Applying direct pressure to the forehead is not effective for managing nosebleeds; pressure should be applied to the nostrils instead.
