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: Assisting the mother into a hands-and-knees position should be prioritized to facilitate fetal rotation and optimize labor progress in the case of persistent occiput posterior fetal position. This position helps in promoting fetal rotation to a more favorable position for delivery by allowing the baby's head to move into the anterior position. It can help alleviate back pain and may help reduce the duration of labor. This simple maneuver can sometimes correct the malposition without the need for interventions like instrumental delivery. It is a non-invasive and effective technique that can be easily implemented by healthcare providers to support the progression of labor.

Correct Answer: C

Rationale: Globulin is the blood protein involved in the immune system. There are different types of globulins, including immunoglobulins (antibodies) that play a crucial role in the body's defense against infections. These antibodies bind to foreign substances, such as bacteria and viruses, helping the immune system to recognize and destroy them. Thrombin is a clotting protein, albumin is a protein responsible for maintaining osmotic balance in the blood, and hemoglobin is a protein found in red blood cells that carries oxygen.

Correct Answer: A

Rationale: Assessing the infant's latch and feeding effectiveness should be prioritized as the initial nursing intervention to address the client's concerns about inadequate milk supply. Poor latch can lead to ineffective milk removal, which may result in decreased milk production. By ensuring the infant is latching correctly and effectively transferring milk, the client's milk supply can be optimized. Education about techniques to increase milk production can be provided following the assessment of feeding effectiveness. Referring to a lactation consultant may be necessary for further evaluation and support if issues persist despite correcting the latch. Supplemental formula feedings should be recommended as a last resort after all other interventions have been attempted and if there are concerns about inadequate nutrition for the infant.

Correct Answer: B

Rationale: Generalizability refers to the extent to which research findings and conclusions can be applied beyond the specific conditions of the study to a larger population or different settings. In this case, if the findings of a study on patients with myocardial infarction (MI) under stress can be applied to all such patients in the whole Philippines, it indicates that the study results are generalizable beyond the specific sample studied. Therefore, the criteria satisfied in this context is generalizability.
