The type of epidemiologic study that is used to describe a group of persons enrolled in a study who share some characteristic of interest and who are followed over a period of time to observe some health outcome is a/an:

Correct Answer: B

Rationale: Cohort studies are types of epidemiological studies that involve a group of individuals who share a common characteristic or experience and are followed over time to observe the development of a particular health outcome. This type of study is useful in determining the incidence of a disease, identifying risk factors, and studying the natural history of a disease. Cohort studies allow researchers to investigate the relationship between exposure and outcome by following participants forward in time. It helps in establishing causality and is particularly useful for studying rare exposures or outcomes. In contrast, cross-sectional studies involve collecting data from a population at a single point in time, experimental studies involve interventions and control groups, and case-control studies involve comparing individuals with a particular health outcome (cases) to those without the outcome (controls) retrospectively.

Correct Answer: A

Rationale: In a pregnant woman presenting with severe abdominal pain, syncope, signs of hypovolemic shock, and gestational age of 6 weeks, the most likely cause is an ectopic pregnancy. An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, commonly in the fallopian tube. As the pregnancy grows and the tube stretches, it can lead to rupture, causing severe abdominal pain, internal bleeding, and signs of shock. This is a life-threatening emergency that requires prompt diagnosis and management. It is important to consider ectopic pregnancy in any pregnant woman presenting with abdominal pain and signs of shock, especially in the first trimester.

Correct Answer: C

Rationale: The patient's presentation of jaundice, ascites, spider angiomas, elevated serum bilirubin levels, prolonged prothrombin time, and hypoalbuminemia are all indicative of cirrhosis. Cirrhosis is a late stage of liver disease characterized by liver scarring and poor liver function. Jaundice, which is the yellowing of the skin and eyes due to elevated bilirubin levels, is a common manifestation of liver dysfunction seen in cirrhosis. Ascites, the accumulation of fluid in the abdomen, is also a common complication of cirrhosis. Spider angiomas, which are small blood vessels near the skin's surface, are a result of altered blood flow in the liver due to cirrhosis. Prolonged prothrombin time and hypoalbuminemia are consequences of reduced liver synthesis function in cirrhosis. Hepatic encephalopathy and hepatorenal syndrome

Correct Answer: B

Rationale: Battery in the context of healthcare refers to the intentional and unauthorized touching of a patient. By applying a body restraint without a doctor's order, Nurse Edna has potentially committed battery against the patient. It is important for healthcare providers to obtain proper authorization before implementing any physical restraints on a patient to avoid legal liabilities such as battery.

Correct Answer: C

Rationale: The sudden onset of shortness of breath, chest pain, and cyanosis in a postpartum client could be indicative of a pulmonary embolism, a potentially life-threatening condition. Therefore, it is crucial to notify the healthcare provider immediately for further assessment and management. Prompt intervention is essential in this situation to prevent any potential complications and ensure the client receives appropriate care as soon as possible. Placing the client in a semi-Fowler's position or administering supplemental oxygen therapy may provide temporary relief, but the priority is to seek immediate medical attention. Consulting with the healthcare provider ensures that the client receives the necessary interventions promptly.

Correct Answer: C

Rationale: The described presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is characteristic of fungal keratitis. Fungal keratitis typically presents with these specific features on clinical examination.

Correct Answer: B

Rationale: The best response for a nurse when a patient expresses dissatisfaction with the care they received during their hospital stay is to listen actively to the patient's concerns, apologize for any shortcomings, and offer to address the issues. It is crucial for healthcare providers to acknowledge the patient's perspective, validate their feelings, and work towards resolving any issues that may have contributed to their dissatisfaction. This approach demonstrates empathy, professionalism, and a commitment to patient-centered care, fostering trust and effective communication between the patient and the healthcare team. Dismissing the patient's concerns (option A), ignoring their dissatisfaction (option C), or telling them that their concerns are unfounded (option D) can further escalate the situation and lead to a breakdown in the patient-provider relationship.

Correct Answer: D

Rationale: The patient mentioned in the scenario presents with delayed puberty, short stature, and a childlike appearance. These symptoms are indicative of growth hormone deficiency (GHD). GHD is a condition where the pituitary gland does not produce enough growth hormone, which is crucial for normal growth and development.

Correct Answer: B

Rationale: When a patient is diagnosed with pneumonia, the breath sounds detected by the nurse on auscultation of the affected area would typically include fine crackles. Fine crackles are discontinuous, high-pitched crackling or rattling sounds heard during inspiration that indicate the presence of fluid in the small airways or alveoli. These crackles are caused by the movement of secretions or exudate within the bronchioles or alveoli, which is a common characteristic of pneumonia. Wheezing sounds are usually associated with conditions such as asthma, bronchitis, or COPD and are caused by narrowed airways. Stridor is a high-pitched, crowing sound that typically indicates an obstruction in the upper airway and is often heard in cases of laryngeal inflammation or foreign body aspiration. Deep and low-pitched breath sounds are more characteristic of conditions like chronic bronchitis.
