Correct Answer: B

Rationale: Dupuytren's contracture is a condition characterized by the thickening and tightening of the tissue beneath the skin of the hand, leading to the fingers being pulled into a bent position. One of the common complications associated with Dupuytren's contracture is the development of a Swan-neck deformity. This deformity is characterized by hyperextension of the proximal interphalangeal joint and flexion of the distal interphalangeal joint. It is important to recognize and address complications like Swan-neck deformity in individuals with Dupuytren's contracture to prevent further functional impairment and disability.

Correct Answer: A

Rationale: The BEST position for a patient in shock is the modified Trendelenburg position. In this position, the patient's legs are elevated above the level of the heart to enhance blood flow back to the heart and vital organs. Placing the patient in the modified Trendelenburg position helps increase venous return, improves cardiac output, and promotes perfusion to vital organs, which can be crucial in managing shock. This position can help stabilize the patient's condition while awaiting further medical intervention.

Correct Answer: D

Rationale: Ovarian torsion is the most likely cause of the pregnant woman's symptoms as described. Ovarian torsion occurs when the ovary twists on its pedicle, leading to compromised blood flow to the ovary. This can cause severe abdominal pain, bloating, and constipation. On examination, an abdominal mass may be palpable due to an enlarged, twisted ovary. Bowel sounds may be diminished due to the effect of the torsion on surrounding structures. Ectopic pregnancy, threatened abortion, and placenta previa are less likely to present with an abdominal mass and diminished bowel sounds.

Correct Answer: B

Rationale: The positive practice environment (PPE) in a health care setting typically includes components such as waste management, infection control, and peer review. However, electrical wires are not a standard component of the PPE in a work setting. Electrical safety is important in a healthcare facility, but it is usually addressed in a separate set of guidelines and protocols focusing specifically on electrical safety and maintenance. Therefore, among the given options, electrical wires are not considered a component of the positive practice environment in the work setting.

Correct Answer: A

Rationale: The combination of recurrent joint pain, swelling, and limited range of motion in multiple joints along with elevated ESR, positive RF, and presence of anti-CCP antibodies is classic for rheumatoid arthritis (RA). Elevated ESR indicates inflammation, positive rheumatoid factor (RF) is an autoantibody commonly found in the serum of patients with RA, and the presence of anti-cyclic citrullinated peptide (anti-CCP) antibodies further supports the diagnosis of RA. These laboratory findings along with the clinical presentation are highly suggestive of rheumatoid arthritis. Systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), and psoriatic arthritis (PsA) can have overlapping symptoms with RA, but the specific combination of elevated ESR, positive RF, and anti-CCP antibodies points more towards RA in this scenario.
