Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: In assessing the health condition of school children, anemia and other blood disorders are more commonly observed in this age group compared to cancer, lice, parasites, fractures, and injuries. Anemia is a common health issue among children due to various factors such as poor nutrition, iron deficiency, and infections. Regular screening for anemia is important in school-age children to prevent long-term complications and to promote their overall health and well-being. While cancer, lice, parasites, fractures, and injuries can also occur in school children, anemia and blood disorders are more prevalent in this age group.

Correct Answer: A

Rationale: The clinical presentation of fatigue, pallor, exertional dyspnea along with the laboratory findings of severe anemia, low serum iron, low transferrin saturation, and elevated TIBC are consistent with iron deficiency anemia. In iron deficiency anemia, there is inadequate iron available for erythropoiesis leading to microcytic hypochromic anemia. The low serum iron and transferrin saturation, along with the elevated TIBC, indicate decreased iron stores and increased iron-binding capacity as the body tries to compensate for the deficiency by increasing absorption and recycling of iron. Anemia of chronic disease typically presents with mild to moderate anemia, normal to low TIBC, and low transferrin saturation due to iron sequestration in macrophages. Sideroblastic anemia usually has elevated serum iron, high saturation, and normal to low TIBC. Thalassemia presents with microcytic hyp

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: Running water in the sink or shower is a priority nursing measure to stimulate the sensation of voiding in postpartum mothers experiencing difficulty due to edema and trauma of the perineum. The sound and sight of running water can help relax the pelvic floor muscles and trigger the urge to void. This technique is commonly used in clinical practice to facilitate voiding and prevent urinary retention in postpartum women.

Correct Answer: A

Rationale: The priority nursing action for a woman diagnosed with uterine rupture during labor is to prepare for immediate cesarean section. Uterine rupture is a serious obstetric emergency that can lead to severe maternal and fetal complications, including hemorrhage, fetal distress, and injury to both mother and baby. A cesarean section is necessary to deliver the baby promptly and address any potential complications, such as controlling bleeding and ensuring the safety of both the mother and the baby. Time is critical in these situations, and prompt surgical intervention is essential to optimize outcomes. Administering intravenous oxytocin or assisting the mother into a hands-and-knees position would not address the immediate risks associated with uterine rupture. Initiating cardiopulmonary resuscitation (CPR) is only necessary if the mother's condition deteriorates to the point of cardiac or respiratory arrest, which may occur as a result of significant hemorrhage or other complications associated with uterine
