For the following situations, state the type of data collection you would perform (i.e., complete database, focused or problem-centered database, follow-up database, emergency database). a. OxyContin overdose

Correct Answer: D

Rationale: The correct answer is D: Emergency database. In the case of an OxyContin overdose, an emergency database would be the most appropriate type of data collection. This is because an overdose requires immediate and urgent attention, necessitating quick and focused data collection to assess the situation and provide necessary interventions promptly. A complete database (choice A) would be too time-consuming and comprehensive for an emergency situation. A focused or problem-centered database (choice B) may not capture all relevant information in a timely manner. A follow-up database (choice C) would be more suitable for monitoring and tracking progress after the initial emergency has been addressed, rather than for the immediate response to an overdose.

Correct Answer: C

Rationale: The correct answer is C because a Hill-Sachs lesion is indeed a compression fracture of the posterolateral aspect of the humeral head caused by abutment against the anterior rim of the glenoid fossa. This occurs during anterior shoulder dislocations. Option A is incorrect because a Hill-Sachs lesion is associated with anterior, not posterior, dislocations. Option B is incorrect because shoulder instability due to a Hill-Sachs lesion depends on the size and location of the defect, not a specific percentage of the articular surface. Option D is incorrect because Speed's test is used to assess biceps tendon pathology, not Hill-Sachs lesions.

Correct Answer: A

Rationale: The correct answer is A: Extensor pollicis brevis (EPB) and abductor pollicis longus (APL). These two tendons make up the first dorsal compartment of the wrist. The EPB is responsible for extending the thumb, while the APL is responsible for abducting the thumb. The other choices are incorrect because they do not accurately represent the tendons that comprise the first dorsal compartment. Choice B incorrectly pairs the extensor pollicis longus (EPL) and abductor pollicis brevis (APB). Choice C lists extensor carpi radialis longus and APL, which are not part of the first dorsal compartment. Choice D pairs extensor carpi radialis brevis and APB, which is also incorrect.

Correct Answer: D

Rationale: The correct answer is D because a swan neck deformity is characterized by hyperextension of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints, along with flexion deformity at the distal interphalangeal (DIP) joint. This leads to a finger resembling a swan's neck shape. Choice A is incorrect because it describes hyperextension at the DIP joint, which is not typical of a swan neck deformity. Choice B is incorrect as it refers to synovitis and ligament disruption at the ulnar styloid, which is unrelated to a swan neck deformity. Choice C is incorrect as it describes hyperextension at the DIP joint instead of flexion deformity. In summary, the correct answer, D, accurately describes the key features of a swan neck deformity, making it the most appropriate choice among the options provided.

Correct Answer: B

Rationale: The correct answer is B: Melanocytes. Melanocytes are responsible for producing melanin, the pigment that gives skin its color. In burn patients, destruction of melanocytes leads to hypopigmentation as there is a reduced or absence of melanin production. Keratinocytes (A) are the most abundant cells in the epidermis, but they do not contribute to skin pigmentation. Basement membrane (C) provides structural support but does not play a direct role in skin pigmentation. Hair follicles (D) are primarily involved in hair growth and do not affect skin pigmentation directly.
