Correct Answer: B

Rationale: The correct answer is 'Upper torso.' In elderly individuals, the center of gravity tends to shift upwards towards the upper torso due to various factors such as changes in posture and muscle strength. Understanding this is crucial for safe ambulation as it helps in maintaining balance and stability. Choices A, 'Arms,' C, 'Head,' and D, 'Feet,' are incorrect. The center of gravity is not typically located in the arms, head, or feet. It is higher up in the body, specifically in the upper torso. Knowing the correct location of the center of gravity is essential for assisting elderly clients in ambulation effectively and preventing falls.

Correct Answer: A

Rationale: Gas pains in the periumbilical area postoperatively are often caused by impaired peristalsis and bowel function. Following abdominal surgery, it is common for peristalsis to be reduced due to surgical manipulation and anesthesia effects. This reduction in peristalsis can lead to the accumulation of gas in the intestines, resulting in gas pains. Infection at the surgical site (Choice B) would present with localized signs of infection such as redness, swelling, warmth, and drainage, rather than diffuse gas pains. Fluid overload (Choice C) would manifest with symptoms such as edema, increased blood pressure, and respiratory distress, not gas pains. Inadequate pain management (Choice D) may lead to increased discomfort, but it is not the primary cause of gas pains in the periumbilical area following a small bowel resection.

Correct Answer: C

Rationale: Injuries at the level of the 2nd cervical vertebra can affect the phrenic nerve, leading to potential impairment of respiratory function. Assessing respiratory function is crucial as compromised breathing can quickly escalate to life-threatening situations. While response to stimuli is important, ensuring adequate oxygenation takes precedence due to the immediate threat to life. Bladder control may be affected by spinal cord injuries at higher levels, but it is not the priority in this scenario. Muscle strength is a potential consequence of cervical spinal cord injury, but assessing respiratory function is more critical in the acute phase.

Correct Answer: B

Rationale: The correct answer is B: Water. Giving sips of water can help dilute the drain cleaner while waiting for emergency transport, which may help reduce the potential harm caused by the ingestion. Choices A, C, and D are incorrect because tea, milk, and soda can interact with the chemicals in the drain cleaner or increase the risk of vomiting, which is not recommended in this situation.

Correct Answer: A

Rationale: The correct answer is to use a picture board with common needs. Clients with expressive aphasia have difficulty speaking but can often understand and use visual aids effectively. Using a picture board helps the client communicate basic needs more easily. Encouraging the client to speak slowly (choice B) may not be effective as the issue lies with expressive language, not speed. Writing down what the client says (choice C) may not always be possible or helpful for immediate communication as it does not address the communication barrier directly. Using hand gestures (choice D) may not be as clear or universally understood as a picture board, which can cause confusion and misinterpretation.
