Correct Answer: C

Rationale: The correct answer is to auscultate before palpation. This ensures that bowel sounds are not altered by physical manipulation. Inspecting the abdomen is a valid step but not the first. Percussing and palpating should come after auscultation to prevent altering bowel sounds or causing discomfort to the client.

Correct Answer: D

Rationale: The correct action for the nurse to take when administering medications through a nasogastric (NG) tube is to dissolve medications separately and flush the tube with sterile water. This is important to prevent interactions between medications and ensure accurate administration. Option A is incorrect because tap water may not be sterile and could lead to contamination. Option B is incorrect as it increases the risk of drug interactions and may affect the effectiveness of each medication. Option C is incorrect as 60 mL of water before each medication may not be enough to ensure proper medication delivery and prevent interactions.

Correct Answer: C

Rationale: The correct answer is C. If sterile solution splashes onto the sterile field, it is considered contaminated. Changing gloves in this situation ensures that the sterility of the dressing change is maintained. Choice A is incorrect as non-sterile gloves would introduce contaminants. Choice B is incorrect as layering gloves can increase the risk of contamination. Choice D is incorrect as covering the sterile field with a sterile drape is not the appropriate action to take in response to contamination.

Correct Answer: B

Rationale: The correct answer is B: Bladder distention. Bladder distention is a sign of catheter occlusion because it indicates a failure to drain urine properly. Bladder spasms (Choice A) are more commonly associated with bladder irritability rather than catheter occlusion. Frequent urination (Choice C) is unlikely in a client with an indwelling catheter as the urine should be draining continuously. Hematuria (Choice D) refers to blood in the urine and is not typically a direct sign of catheter occlusion.

Correct Answer: C

Rationale: The correct answer is C: 'Use cotton fabrics when oxygen is in use.' When a client is on oxygen therapy, it is essential to use cotton fabrics to reduce the risk of static electricity, which can ignite in the presence of oxygen. Choices A, B, and D are incorrect. Removing the oxygen tubing during meals is not necessary as long as proper precautions are taken to avoid tripping hazards. Synthetic fabrics should be avoided while using oxygen therapy to prevent static electricity buildup. Increasing oxygen flow during physical activity should be done according to the healthcare provider's instructions, not indiscriminately.
