Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: C

Rationale: Incident reports are a crucial tool for capturing data on adverse events, near misses, and other incidents within a healthcare institution. These reports help in analyzing patterns, identifying areas for improvement, and implementing quality and safety measures. Therefore, incident reports themselves are not something that needs to be prevented; instead, they are a critical part of the risk management process to enhance patient safety and quality of care.

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: B

Rationale: In the scenario of a woman in active labor experiencing a prolonged second stage with inadequate expulsive efforts, the appropriate nursing intervention to facilitate fetal descent would be to apply fundal pressure. Fundal pressure, or applying pressure on the upper abdomen just above the uterine fundus, can help in directing the fetal head downwards and aiding in the descent through the birth canal. It is important to note that fundal pressure should be applied carefully and with proper technique to prevent excessive force that could potentially harm the mother or the baby. Encouraging the mother to push forcefully during contractions can be helpful, but the addition of fundal pressure can provide extra assistance in cases of inadequate progress. Immediate cesarean section may be considered if other interventions are unsuccessful or if there are concerns for fetal distress. Administering intravenous magnesium sulfate for uterine relaxation is not indicated in this situation.

Correct Answer: A

Rationale: Option A, "Can we talk about Mrs. Santos?" is indicative of a collaborative relationship between the nurse and the attending physician. It shows open communication and a willingness to discuss the patient's case together, which is essential for optimal patient care. This statement implies teamwork and a shared responsibility for the patient's well-being. The other options either lack a collaborative tone, show concern without inviting discussion, or suggest a dismissive attitude towards addressing the patient's needs.

Correct Answer: B

Rationale: A living will is a legal document that allows an individual to express their wishes regarding medical treatment in the event they become unable to make decisions. It specifically outlines the medical treatments a person chooses to refuse or accept under certain circumstances. It is important to differentiate a living will from a durable power of attorney, which designates someone to make healthcare decisions on behalf of the individual when they are unable to do so, and advance directives, which encompass both a living will and a durable power of attorney for healthcare. The living will serves as a guide for healthcare professionals and family members to honor the individual's preferences for medical care.
