The time is 2:40 in the afternoon. Using a 24 hour clock, this would be recorded as:

Correct Answer: C

Rationale: 1440 is 2:40 p.m. (14:40) in 24-hour format, not 1240 , 240 p.m. , or 0240 . PSWs use this e.g., logs for precision. Errors risk timing issues; this fits. This standard ensures clear records, a PSW detail in care.

Correct Answer: A

Rationale: Delegation gives non-controlled acts e.g., bathing unlike assignment , orders , or transfer . PSWs receive this e.g., tasks for care. Misnaming risks confusion; this fits. This defines scope, a PSW role in team work.

Correct Answer: B

Rationale: Contractures permanent shortening of muscles or joints result from immobility, reducing function and causing pain. PSWs play a key role in prevention. Forcing exercises risks injury and ignores client capability. Grooming assistance supports hygiene, not joint mobility. Encouraging participation is ideal for able clients but impractical for those unable to move independently. Passive range of motion exercises , where the PSW moves the client's limbs, maintain flexibility and circulation without requiring client effort, making it the most effective method for immobile individuals. This aligns with restorative care principles in healthcare, preventing contractures by keeping joints supple, and is a standard PSW task, confirming it as the correct choice.

Correct Answer: A

Rationale: The spinal cord in adults averages about 45 cm , extending from the brainstem to the L1-L2 vertebrae. This length, roughly 17-18 inches, is consistent across medical references like Gray's Anatomy, varying slightly by individual height. Options 40 cm , 35 cm , and 30 cm underestimate this, with 40 cm being closest but still short. Its role in transmitting nerve signals relies on this span, ending where the cauda equina begins. PSWs need this knowledge for understanding spinal injuries or positioning, and 45 cm aligns with standard anatomical data, confirming it as the correct measurement.

Correct Answer: A

Rationale: The pericardium is the heart's outer layer, a sac enclosing it to protect and anchor it, with fibrous and serous parts. The second layer aligns with the myocardium (muscle), and the inner layer is the endocardium, neither called pericardium. 'None of the above' dismisses the correct term. Cardiac anatomy, relevant for PSWs monitoring heart conditions, identifies the pericardium as the external protective covering, as in Netter's Atlas, making 'Outer layer' the precise and correct answer.
