During surgery, it is found that a client with adenocarcinoma of the rectum has positive peritoneal lymph nodes. What is the next most likely site of metastasis?

Correct Answer: C

Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

Correct Answer: C

Rationale: Naprosyn (naproxen) is known to cause upper-gastrointestinal (UGI) bleeding due to its effects on the stomach lining. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the stomach and increase the risk of UGI bleeding. On the other hand, Cardizem (diltiazem), Elavil (amitriptyline), and Corgard (nadolol) are not typically associated with UGI bleeding. Cardizem is a calcium channel blocker used for hypertension and angina, Elavil is a tricyclic antidepressant, and Corgard is a beta-blocker used for hypertension.

Correct Answer: A

Rationale: A small amount of bubbling is a normal finding in the water seal of a pleural drainage system when a client coughs. It is only a problem to find continuous, excessive bubbling in the water seal, which indicates a leak. Checking the system for leaks would be appropriate if there is continuous, excessive bubbling. Clamping the chest tube or changing the drainage system is not necessary in response to a small amount of bubbling during a cough, as this is considered a normal finding.

Correct Answer: C

Rationale: Correct. When using a rigid splint, it is essential to pad the spaces between the body part and the splint to ensure proper immobilization and increase client comfort. This padding helps prevent pressure points and ensures a proper fit of the splint without causing discomfort. Placing the client on a stretcher or a long spine board before splinting (choices A and B) may be necessary for transportation but does not directly relate to the proper use of a rigid splint. Ensuring that the splint conforms to the body curves (choice D) is important but not as crucial as padding the spaces to prevent discomfort and ensure proper immobilization.

Correct Answer: D

Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.
