Correct Answer: B

Rationale: In the situation of an obstetric emergency requiring immediate delivery, the priority nursing action is to prepare the delivery room for the birth. This involves ensuring that all necessary supplies and equipment are readily available, the bed is adjusted to the appropriate position, and the healthcare team is prepared to assist with the birth. By expeditiously preparing the delivery room, the healthcare team can facilitate a safe and timely delivery for both the mother and the baby. Notifications to the healthcare provider, administering intravenous fluids, and continuous fetal monitoring can be done simultaneously but preparing the delivery room takes precedence to ensure a prompt response to the emergent situation.

Correct Answer: B

Rationale: Cultural competence is the process of acquiring specific knowledge, skills, and attitudes to effectively work with individuals from diverse cultural backgrounds. It involves understanding and respecting the values, beliefs, languages, and practices of different cultures in order to provide appropriate care and services. Cultural competence goes beyond just learning about different cultures; it requires the development of skills and attitudes that promote effective communication, understanding, and collaboration with individuals of diverse backgrounds. This includes being aware of one's own biases, being open-minded, and adapting practices to be inclusive and respectful of cultural differences. Ultimately, cultural competence is essential in providing high-quality, respectful, and effective care to clients from various cultural backgrounds.

Correct Answer: A

Rationale: Selective IgA deficiency is a primary immunodeficiency disorder characterized by low or absent levels of immunoglobulin A (IgA) in the blood. Since IgA plays a crucial role in mucosal immunity and defense against pathogens at mucosal surfaces, individuals with this deficiency are more susceptible to recurrent bacterial infections, particularly of the respiratory and gastrointestinal tracts. In contrast, severe combined immunodeficiency (SCID) is a more severe immunodeficiency disorder affecting T and B lymphocytes, chronic granulomatous disease (CGD) is a disorder of phagocytes, and autoimmune hemolytic anemia is an autoimmune disease involving red blood cells, none of which are directly associated with selective IgA deficiency.

Correct Answer: B

Rationale: The symptoms described - gradual-onset weakness, spasticity, hyperreflexia, positive Babinski sign, and demyelinating plaques in the white matter of the brain and spinal cord - are indicative of multiple sclerosis (MS). MS is an autoimmune disease where the body's immune system attacks the myelin sheath, leading to the formation of plaques in the central nervous system. The characteristic symptoms of MS include weakness, spasticity (stiffness in muscles), hyperreflexia (exaggerated reflex responses), and positive Babinski sign (upward movement of the big toe). While ALS (Amyotrophic lateral sclerosis) presents with progressive muscle weakness and atrophy without sensory involvement and demyelinating plaques, Guillain-Barré syndrome (GBS) is typically an acute inflammatory demyelinating polyneuropathy affecting peripheral nerves rather than the central nervous system, and myast

Correct Answer: D

Rationale: Before any procedure, it is crucial to ensure that you have the proper authorization and guidelines in place. By checking the physician's order and the patient care plan, you confirm that suctioning is indeed needed and that you follow the specific instructions for that patient. This step helps ensure patient safety and effective care delivery. Once you have verified this information, you can proceed with gathering equipment, performing hand hygiene, and assessing the patient's condition as necessary.
