Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: Marlene opening up to the nurse about their financial difficulty indicates that she feels comfortable enough to share personal information with the nurse. This signals the establishment of a trusting relationship between Marlene and the nurse, as Marlene feels safe and supported enough to disclose sensitive information. Building trust is a crucial aspect of any professional relationship, especially in healthcare settings, as it fosters open communication, encourages honesty, and ultimately leads to better outcomes for the patient. It is an essential foundation for providing effective care and support to individuals in need.

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: 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.

Correct Answer: A

Rationale: Nursing intervention should prioritize providing education on proper incisional wound care techniques to promote optimal healing of the abdominal incision. This may include instructions on how to clean the incision site, signs and symptoms of infection, and when to seek medical attention. Proper wound care can help prevent complications such as infection and dehiscence, leading to better outcomes for the client. Administering prophylactic antibiotics, encouraging the use of abdominal binders, and instructing the client on activity restrictions are also important interventions, but educating the client on wound care techniques is crucial for their active participation in their recovery process.

Correct Answer: B

Rationale: An abdominal ultrasound is the imaging test that uses a transducer and is most commonly ordered by physicians to detect gallstones. This non-invasive procedure allows the physician to visualize the gallbladder and detect any presence of gallstones. The transducer emits sound waves that bounce off the gallstones, creating images that can be seen on a screen. This imaging test is safe, reliable, and effective in diagnosing gallstones without the use of radiation or contrast dye.
