Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: The correct instruction for using a metered-dose inhaler (MDI) with a spacer for a patient with COPD is to inhale slowly and deeply while pressing the canister. This technique helps ensure that the medication reaches the lungs effectively. Inhaling slowly and deeply allows the medication to be properly delivered to the airways, maximizing its effectiveness in treating the symptoms of COPD. This instruction helps the patient coordinate pressing the canister with their inhalation, which is crucial for proper medication delivery in COPD management.

Correct Answer: C

Rationale: Bone pain in the back of the ribs is a classic manifestation of multiple myeloma. Multiple myeloma is a type of cancer that primarily affects plasma cells in the bone marrow, leading to weakened bones and bone pain. Patients with multiple myeloma often experience bone pain in areas such as the ribs, spine, and pelvis. The bone pain is typically persistent and worsens with movement or pressure. Additionally, other common symptoms of multiple myeloma include anemia, kidney damage, recurrent infections, and elevated calcium levels in the blood.

Correct Answer: B

Rationale: Phlebitis is the most common complication that patients may contract while on IV therapy. Phlebitis is the inflammation of the vein where the IV is inserted, which can cause redness, pain, and swelling along the vein. It can be caused by mechanical irritation, chemical irritation, or infection from the IV catheter. Prompt removal of the IV catheter and appropriate treatment are necessary to manage phlebitis and prevent further complications. While embolism, cardiac overload, and aneurysm are potential complications of IV therapy, phlebitis is more commonly seen in clinical practice.

Correct Answer: A

Rationale: In primary care nursing, typically, one nurse is designated to have 24-hour responsibility for care planning and coordination for each patient. This helps ensure continuity of care and accountability. By having one nurse overseeing all aspects of the patient's care, it allows for a more personalized and coordinated approach that puts the patient at the center of the care structure. Having one primary care nurse also promotes better communication, efficiency, and consistency in managing the patient's health and well-being.

Correct Answer: A

Rationale: Somatic hypermutation is the mechanism responsible for generating diversity in the antigen-binding sites of immunoglobulins. During somatic hypermutation, point mutations are introduced into the variable regions of immunoglobulin genes in B cells. These mutations occur randomly and lead to a wide range of amino acid changes in the antigen-binding sites of antibodies. As a result, a diverse repertoire of antibodies with varying specificities for different antigens is created. Gene rearrangement and isotype switching are other mechanisms that contribute to antibody diversity but do not specifically target the antigen-binding sites. Clonal expansion, on the other hand, refers to the proliferation of specific B cell clones after activation by antigens, which amplifies the immune response but does not directly impact the diversity of antigen-binding sites.
