General Practice Flashcards

When positioning a patient, which of the following should be taken into account? 1. Patency of the airway is the prime concern when positioning a patient 2. Pressue injuries are most common after surgical procedures lasting one hour or longer. 3. An anesthetized patient with muscle paralysis is at increased risk for muscle strain 4. The most common sites of peripheral nerve injury are the divisions of the brachial plexus and the ulnar, radial, peroneal, and facial nerves

Answer: 1, 2, and 4 only

When positioning a patient for surgery, ensuring a patent airway (1) is the top priority to maintain oxygenation. Pressure injuries (2) are a significant risk, especially during procedures lasting an hour or longer, necessitating careful padding. Anesthetized patients with muscle paralysis are highly vulnerable to peripheral nerve injuries (4) due to the absence of protective reflexes, making precise positioning critical. Statement 3 is incorrect as muscle paralysis *increases* the risk of muscle strain, not decreases it.

What arteries can be separated during a AAA resection and then reanastomosed to the graft?

Answer: renal

During an Abdominal Aortic Aneurysm (AAA) resection, the diseased segment of the aorta is replaced with a graft. If the renal arteries originate from the aneurysmal portion, they must be carefully detached and then reanastomosed (reconnected) to the new graft. This crucial step ensures continued blood flow to the kidneys, preserving their function after the repair.

A jejunojejunostomy may be performed when a loop of the jejunum is anastomosed end to side with the esophagus during a total gastrectomy.

Answer: prevent regurgitation esophagitis

After a total gastrectomy, a jejunojejunostomy (specifically an esophagojejunostomy) is performed to reconstruct the digestive tract. This procedure helps prevent the reflux of bile and pancreatic enzymes from the small intestine back into the esophagus. Such reflux would otherwise cause severe irritation and inflammation, known as regurgitation esophagitis, which this anastomosis effectively mitigates.

Which of the following applies to a sharps container's requirements? 1. self-closing lid to prevent overfilling 2. biohazard labels and color coding 3. durable, closable, leakproof, and puncture resistant 4. lids which allow sharps to enter by gravity

Answer: 2, 3, and 4 only

Sharps containers are essential for the safe disposal of contaminated sharp objects, preventing injuries and infection spread. They must feature clear biohazard labels and color coding (2) for easy identification. Crucially, they need to be durable, closable, leakproof, and puncture-resistant (3) to safely contain hazardous materials, and their lids should allow sharps to enter by gravity (4) to minimize direct contact.

Among the structures most frequently implicated in a sliding left indirect hernia

Answer: sigmoid

A sliding hernia occurs when a retroperitoneal organ forms part of the hernia sac wall. In the case of a left indirect inguinal hernia, the sigmoid colon is the structure most commonly involved in this type of hernia. Its anatomical position and mobility allow it to 'slide' into the inguinal canal, becoming a component of the hernia sac.

Another name for a suture ligature is

Answer: a stick tie

A suture ligature is a surgical technique where a suture is passed through a vessel or tissue and then tied around it. This method is commonly referred to as a 'stick tie' because the suture 'sticks' into the tissue. It provides a more secure ligation than a simple tie, preventing the suture from slipping off, especially on larger or more fragile vessels.
