Coma patient, wrong

Correct Answer: A

Rationale: The correct answer is A: Use straight catheter. In a coma patient, using a straight catheter is more appropriate because it is a temporary solution for relieving urinary retention without the risks associated with leaving an indwelling catheter in place long-term. Indwelling catheters can increase the risk of infection and discomfort, especially in comatose patients who may not be able to communicate any issues. Additionally, straight catheters are less invasive and can be used as needed, reducing the risk of complications and promoting better patient outcomes.

Correct Answer: B

Rationale: The correct answer is B: Sustained pressure. Bed sores, also known as pressure ulcers, develop due to prolonged pressure on the skin that hinders blood flow, leading to tissue damage. The constant pressure restricts oxygen and nutrients to the affected area, causing the skin and underlying tissues to break down. This can happen when a person remains in one position for an extended period, such as when lying in bed or sitting in a wheelchair. Infection (choice A) can occur as a complication of bed sores, but it is not the immediate cause. Choices C and D are incomplete and do not provide a logical explanation for the development of bed sores.

Correct Answer: A

Rationale: The correct answer is A: allow abduction. After a hip replacement surgery, allowing abduction (movement of the leg away from the midline of the body) is important to prevent dislocation of the new hip joint. Abduction helps maintain stability and proper alignment of the hip joint. Adduction (movement of the leg towards the midline) should be limited to prevent strain on the new hip joint. Choice B is incorrect because adduction can increase the risk of hip dislocation post-surgery. Choices C and D are not provided, but they would be incorrect as they are not relevant to the correct management of a hip replacement.

Correct Answer: A

Rationale: The correct answer is A: Caused by trauma. A wheel formed on the arm is a common manifestation of dermatographia, a condition where pressure on the skin causes it to become raised and red. Trauma, such as scratching or rubbing the skin, triggers this reaction in individuals with dermatographia. The other choices are incorrect because dermatographia is not caused by a reaction to any external substance or allergen (choice B), and the options C and D are left blank as they do not provide any relevant information related to the formation of a wheel on the arm.

Correct Answer: A

Rationale: Step 1: Breathing into a brown bag helps rebalance oxygen and carbon dioxide levels in the blood. Step 2: Excessive breathing lowers carbon dioxide levels causing symptoms like dizziness, tingling. Step 3: Breathing into a brown bag helps retain carbon dioxide, reducing symptoms quickly. Step 4: Performing Coach breathing, a breathing technique, would not address the underlying issue of low carbon dioxide levels. Step 5: Choice C and D are not provided, so irrelevant to the question.
