Correct Answer: D

Rationale: The correct answer is D: Diabetes insipidus. This condition is characterized by excessive thirst, large volumes of dilute urine, low urine osmolality, hypernatremia, and elevated serum osmolality. The underlying cause is a deficiency in or insensitivity to antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Hyperthyroidism (choice A) and hypothyroidism (choice B) do not directly affect urine concentration. While diabetes mellitus (choice C) can also present with polyuria and polydipsia, it would typically have high urine osmolality due to the presence of glucose. Therefore, diabetes insipidus is the most likely endocrine disorder responsible for these specific symptoms.

Correct Answer: C

Rationale: The correct answer is C: Macrophages. Macrophages are antigen-presenting cells that engulf pathogens and present their antigens to T cells, initiating an immune response. They express major histocompatibility complex (MHC) molecules necessary for T cell recognition. B cells also present antigens but primarily to B cells for antibody production. NK cells are involved in killing infected cells, not antigen presentation. Eosinophils are mainly involved in allergic responses and defense against parasites, not antigen presentation.

Correct Answer: C

Rationale: Step 1: Previous pregnancy experience is crucial for understanding the patient's obstetric history and potential risks. Step 2: It helps in identifying any complications or issues that may arise during the current pregnancy. Step 3: Laboratory results, prenatal check-up records, and diagnostic test results provide additional information but do not offer insights into the patient's past pregnancy experiences. Summary: Choice C is the most important as it directly relates to the patient's obstetric history, while the other options focus on current data that may not provide the same level of context.

Correct Answer: C

Rationale: The correct answer is C: Primary prevention. In this scenario, the clinic focuses on preventing disease before it occurs through health education and immunization. Primary prevention aims to promote general health and prevent the onset of diseases. It targets the entire population to reduce the risk of disease occurrence. Incorrect Choices: A: Diagnosis and treatment - This choice involves identifying and treating existing health conditions, which is not the primary focus of a clinic designed for health education and immunization. B: Secondary prevention - This choice involves early detection and treatment of diseases to prevent complications, which is more focused on individuals who already have risk factors or symptoms, not on the general population. D: Tertiary prevention - This choice involves managing and treating complications of diseases to prevent further deterioration, which is not the primary goal of a clinic focused on health education and immunization.

Correct Answer: A

Rationale: Precipitous labor is characterized by rapid cervical dilation and descent of the fetal presenting part, leading to a shortened labor duration of less than 3 hours. This rapid progression can increase the risk of maternal complications, such as postpartum hemorrhage. Postpartum hemorrhage is defined as excessive bleeding of more than 500 ml after vaginal delivery or more than 1000 ml after cesarean delivery. The rapid delivery in precipitous labor can result in inadequate uterine contractions after delivery, leading to poor uterine tone and potential postpartum hemorrhage due to uterine atony. Therefore, the nurse should anticipate postpartum hemorrhage as a potential maternal complication in a woman experiencing precipitous labor.
