Which of the following procedures would be MOST helpful to Nurse Victor to confirm the underlying cause of cardiogenic shock?

Correct Answer: C

Rationale: Monitoring cardiac enzymes would be most helpful to Nurse Victor to confirm the underlying cause of cardiogenic shock. Cardiac enzymes are specific markers in the blood that indicate damage to the heart muscle, such as troponin and creatine kinase-MB (CK-MB). When a patient experiences cardiogenic shock, there is usually damage to the heart muscle which leads to the release of these enzymes into the bloodstream. Monitoring cardiac enzymes can help confirm if the cause of cardiogenic shock is related to myocardial infarction or another cardiac issue. This information is crucial for determining the appropriate treatment and management plan for the patient. Monitoring pulmonary artery pressure, mean arterial pressure, and central venous pressure may provide important hemodynamic information but may not directly confirm the underlying cause of cardiogenic shock.

Correct Answer: A

Rationale: The development of autoantibodies such as antinuclear antibodies (ANA) and anti-double-stranded DNA (anti-dsDNA) antibodies in systemic lupus erythematosus (SLE) is primarily attributed to a loss of self-tolerance. Self-tolerance refers to the immune system's ability to recognize and differentiate self-antigens from foreign antigens. In individuals with SLE, there is a breakdown in immune tolerance mechanisms, leading to the production of autoantibodies against self-antigens like nuclear components (e.g., DNA, RNA, histones). This loss of self-tolerance results in the immune system targeting and attacking its tissues, leading to the systemic inflammation and tissue damage characteristic of SLE. The presence of elevated levels of ANA and anti-dsDNA antibodies in this patient suggests an autoimmune response against nuclear material, further supporting the role of self-tolerance breakdown in SLE

Correct Answer: C

Rationale: The suicide of her mother is the most probable historical data that led to post-traumatic stress disorder. Experiencing the suicide of a close family member, especially a parent, can be an extremely traumatic event that can have long-lasting psychological effects. Witnessing or dealing with such a tragic loss can lead to feelings of helplessness, depression, guilt, and intense emotional distress, all of which are common in individuals with post-traumatic stress disorder (PTSD). This significant and distressing event could have a profound impact on the individual's mental health and well-being, contributing to the development of PTSD symptoms such as intrusive memories, avoidance behaviors, negative mood alterations, and changes in arousal or reactivity.

Correct Answer: A

Rationale: Pre-eclampsia is a serious condition that can occur during pregnancy, usually after 20 weeks gestation. It is important to screen for pre-eclampsia early in the pregnancy to monitor and manage the condition effectively. Screening for pre-eclampsia typically begins in the first trimester of pregnancy to identify any risk factors and provide appropriate care for the patient. Therefore, Nurse Vera informing the patient to get screened for pre-eclampsia in the first term of pregnancy is the most appropriate time to start monitoring for this condition.

Correct Answer: C

Rationale: The correct answer, C, reflects a health resource problem. The absence of a midwife in the community means that there is a lack of a critical health resource necessary for providing essential health services, especially for pregnant women and infants. This directly impacts the access to healthcare services and can contribute to negative health outcomes, such as high maternal mortality rates. The other options do not directly address a health resource problem but rather focus on specific issues or conflicts within the community.
