Which of the following is a guideline for cast care?

Correct Answer: B

Rationale: The correct answer is B: Pad the edge of the cast to reduce sharp edges. This is important to prevent skin irritation and injury from the rough edges of the cast. By padding the edges, it helps to distribute pressure evenly and decrease the risk of abrasions. Choice A is incorrect because using a sharp scratcher inside the cast can lead to skin damage and infections. Choice C is incorrect as keeping the cast damp or wet can cause skin maceration and increase the risk of infection. Choice D is incorrect as keeping the extremity low close to the ground can lead to swelling and discomfort.

Correct Answer: B

Rationale: The correct answer is B: Return fluid to the circulatory system. The lymphatic system helps maintain fluid balance by collecting excess fluid from tissues and returning it to the bloodstream. This process, known as lymphatic drainage, helps prevent swelling and maintains proper circulation. Choices A, C, and D are incorrect as the immune and lymphatic systems do not primarily function to provide reflex centers for respiration, protect internal organs, or absorb nutrients.

Correct Answer: B

Rationale: The correct answer is B: Central venous line. This type of intravenous line is inserted into a large vein in the body to provide access for medications, fluids, and blood products. It is used for long-term administration, monitoring of central venous pressure, and rapid fluid resuscitation. A: Peripheral line is inserted into a smaller vein in the extremities. C: Gastrostomy line is used for enteral nutrition and is inserted directly into the stomach. D: Nasogastric line is inserted through the nose into the stomach for gastric decompression or feeding. In summary, the central venous line is the correct choice for accessing a large vein in the body for various medical interventions.

Correct Answer: C

Rationale: The correct answer is C: Never. Leaving something blank on a job application is generally not recommended as it may give the impression of being unprepared or careless.

It is better to acknowledge any gaps in information and offer explanations or alternative contact details if necessary. Therefore, the best practice is to always complete all sections of a job application to the best of one's ability. Choices A, B, and D are incorrect because applicants should make an effort to provide all relevant information or at least acknowledge any missing details.
