Correct Answer: A

Rationale: The correct answer is A. Positioning the irrigating solution bag 30 inches below the stoma would cause discomfort and ineffective irrigation as the bag should be positioned at a lower level. Option B is incorrect because a closed system for irrigation is the preferred method for colostomy irrigation. Option C is incorrect as colostomy irrigation is typically done once a day unless otherwise instructed by a healthcare provider. Option D is incorrect as the stoma should be cleaned with mild soap and water to prevent skin irritation and damage.

Correct Answer: C

Rationale: After a client experiences severe coughing following nasogastric tube feedings, it is crucial to verify proper tube placement. Checking the pH of fluid withdrawn from the tube helps confirm the tube's correct positioning. Option A is incorrect because further action is necessary to ensure the client's safety. Option B is inappropriate as it suggests stopping the feeding without assessing the tube's placement. Option D is incorrect as injecting air into the tube may lead to further complications if the tube is not positioned correctly.

Correct Answer: A

Rationale: A bounding pulse is indicative of fluid volume excess. In this case, the client's weight gain and edematous ankles already suggest fluid volume overload. A bounding pulse occurs due to increased blood volume and pressure. Choices B, C, and D are not indicative of fluid volume excess. Decreased blood pressure, dry mucous membranes, and weak pulse are more commonly associated with conditions such as dehydration or hypovolemia, where there is a decrease in fluid volume rather than an excess.

Correct Answer: B

Rationale: When a patient is placed in the Sims' position, the nurse should observe pressure points on the ileum, clavicle, humerus, knees, and ankles. Choice A is incorrect as the chin and hips are not typically pressure points in the Sims' position. Choice C is incorrect as the shoulder and anterior iliac spine are not commonly observed pressure points in this position. Choice D is also incorrect as the occipital region of the head, coccyx, and heels are not pressure points commonly associated with the Sims' position.

Correct Answer: A

Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.
