Correct Answer: B

Rationale: The correct answer is B: IgA. In multiple myeloma, there is a proliferation of abnormal plasma cells, leading to a decrease in normal antibody production. IgA is the most abundant immunoglobulin in mucosal secretions and plays a crucial role in mucosal immunity. Therefore, a deficiency in IgA is common in patients with multiple myeloma. IgG is the most abundant immunoglobulin in the blood and is typically less affected in multiple myeloma. IgM is the first antibody produced in response to an infection and is less likely to be deficient in this case. IgE is primarily involved in allergic responses and is not typically affected in multiple myeloma.

Correct Answer: C

Rationale: The correct answer is C because the documentation lacks essential details regarding the contents of the complaints, reasons for refusing the meal, and the nature of the fall. This information is crucial for understanding the patient's condition and providing appropriate care. Choice A is not directly related to the documentation provided. Choice B is about referrals and medications, which are not mentioned in the documentation. Choice D is about eating time and medications for pain, which are also not relevant to the documentation provided. Therefore, the correct answer is C as it addresses the specific missing information in the nurse's notes.

Correct Answer: B

Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.

Correct Answer: B

Rationale: One potential maternal condition that may contribute to abnormal labor progression with slow cervical dilation despite regular contractions is pelvic outlet obstruction. This can occur if the maternal pelvis is too small, misshapen, or has an obstruction such as a fibroid tumor. The inadequate space in the pelvis can prevent the fetus from descending properly and can result in a prolonged or difficult labor. If suspected, interventions such as a cesarean delivery may be necessary to prevent complications for both the mother and baby. It is essential for the nurse to assess for signs of pelvic outlet obstruction and work with the healthcare team to address any issues promptly to ensure a safe delivery.

Correct Answer: A

Rationale: Rationale: A person's compliance with diabetes management can be influenced by economic status, as financial concerns can impact access to medications, healthy food, and healthcare. This can affect treatment adherence and overall health outcomes. Choice A is correct because addressing economic factors is important in promoting compliance. Choices B, C, and D are incorrect as they do not directly address the relationship between economic status and compliance with diabetes management.
