Which of the following structures is responsible for storing and concentrating bile produced by the liver until it is needed for digestion?

Correct Answer: B

Rationale: The gallbladder is the structure responsible for storing and concentrating bile produced by the liver until it is needed for digestion. Bile is a digestive fluid that helps in the breakdown of fats during the digestive process. When food containing fats enters the small intestine, the gallbladder contracts and releases bile into the small intestine to aid in the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, storing it until it is needed for digestion.

Correct Answer: A

Rationale: The patient's presentation of fatigue, weakness, jaundice, elevated indirect bilirubin levels, reticulocytosis, and positive Coombs test is consistent with hemolytic anemia. Among the options provided, hereditary spherocytosis is the most likely condition to cause these findings.

Correct Answer: D

Rationale: The clinical presentation of chest pain, dyspnea, and a friction rub heard on auscultation is suggestive of pericarditis. The diffuse ST-segment elevation seen on the electrocardiogram (ECG) is a classic finding in pericarditis, known as the "universal sign." In contrast, stable angina typically presents with chest pain on exertion that is relieved by rest or nitroglycerin, while unstable angina presents with chest pain at rest or with minimal exertion. Acute myocardial infarction would typically present with ST-segment elevation in specific leads correlating with the area of myocardial ischemia/infarction. However, in the context of diffuse ST-segment elevation and symptoms suggestive of inflammation (friction rub), the most likely diagnosis is pericarditis.

Correct Answer: A

Rationale: Nurses play a crucial role as collaborators in the diagnostic process of psychiatric patients. While nurses themselves do not diagnose psychiatric conditions, they work closely with other healthcare providers such as psychiatrists and psychologists in assessing and monitoring patients' mental health status. Nurses gather valuable information, observe patients' behaviors, and communicate effectively with the healthcare team to contribute to the overall diagnostic process. By actively participating in assessments and evaluations, nurses help ensure accurate diagnoses and appropriate treatment plans for psychiatric patients.

Correct Answer: D

Rationale: Negligence is the failure to take proper care in doing something, which results in harm or injury to someone else. In this scenario, the client falling out of bed because side rails were not used indicates a lack of proper care or attention by the staff or caregiver responsible for the client. It shows a failure to protect the client from harm, which aligns with the definition of negligence. This situation does not fit the definitions of a felony, battery, or assault.

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.

Correct Answer: A

Rationale: A normal thyroid state is referred to as euthyroid, which means the thyroid gland is functioning within normal parameters and the levels of thyroid hormones in the body are balanced. In contrast, hyperthyroid refers to an overactive thyroid gland, causing excessive production of thyroid hormones, while parathyroid is a different gland responsible for regulating calcium levels in the body. Panthroid is not a recognized medical term related to thyroid function. Therefore, the best response to the patient's question about the normal thyroid state is "Euthyroid."

Correct Answer: A

Rationale: When planning for a client's care, a primary consideration is to prevent problems related to immobility. Immobility can lead to a range of complications such as pressure ulcers, muscle weakness, joint contractures, and decreased circulation. To maintain the client's overall health and well-being, it is essential to address mobility issues and implement strategies to prevent complications associated with immobility. By prioritizing interventions that promote movement and prevent immobility-related problems, the client's quality of life can be improved and potential health risks mitigated.

Correct Answer: C

Rationale: Methotrexate is a medication commonly used in the treatment of rheumatoid arthritis. It is known to have potential hepatotoxic effects, meaning it can harm the liver. Monitoring liver function tests (such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin levels) is essential to detect any liver damage early on during methotrexate therapy. By closely monitoring liver function tests, healthcare providers can assess the medication's impact on the liver and determine if any dose adjustments or discontinuation of the drug is necessary to prevent further liver damage. Regular monitoring of liver function tests helps ensure the safe and effective use of methotrexate in patients with rheumatoid arthritis.
