Correct Answer: C

Rationale: The correct answer is to reposition the client every 4 hours. Repositioning the client helps prevent pressure injuries caused by urinary incontinence by relieving pressure on vulnerable areas of the skin. Choice A, using a heating pad for comfort, is not directly related to preventing pressure injuries. Choice B, applying a barrier cream to the skin, may help protect the skin but does not address the underlying cause of pressure injuries. Choice D, changing the client's position every 2 hours, is more frequent than necessary and may not be as effective in preventing pressure injuries as repositioning every 4 hours.

Correct Answer: A

Rationale: Nausea is a common symptom of intolerance to enteral feedings. When a client experiences nausea during enteral feeding, it can indicate issues such as feeding tube placement problems, formula intolerance, or gastroparesis. Nausea can lead to vomiting and further complications if not addressed promptly. Decreased heart rate, weight gain, and fever are not typically associated with intolerance to enteral feedings and would not be the primary indicators for this situation.

Correct Answer: C

Rationale: The correct answer is C because a client with dehydration and inflammatory bowel disease is stable enough for care by an LPN. This condition does not require complex interventions that would necessitate a higher level of nursing care. Choice A is incorrect as administering IV antibiotics for pneumonia requires a higher level of nursing expertise. Choice B is incorrect because monitoring for dehydration may involve assessing vital signs and making critical decisions. Choice D is incorrect as providing care for surgical wound care involves wound assessment, dressing changes, and monitoring for signs of infection, which typically require a registered nurse.

Correct Answer: C

Rationale: The correct action for the nurse to take when administering medications through an NG tube is to dissolve each medication separately and flush with water between medications. This practice helps prevent interactions between medications and ensures that each medication is delivered effectively. Option A is incorrect as mixing all medications together can lead to chemical interactions or alter the effectiveness of the medications. Option B is incorrect because flushing the NG tube with air is not recommended and may cause harm. Option D is incorrect as administering all medications at the same time does not allow for proper absorption and interaction control.

Correct Answer: B

Rationale: The correct answer is B: Increased hematocrit. Increased hematocrit indicates hemoconcentration, which is a sign of fluid volume deficit. When there is a decrease in fluid volume in the body, the blood becomes more concentrated, leading to an increase in hematocrit levels. Choices A, C, and D are incorrect because decreased BUN levels, increased white blood cell count, and decreased hematocrit are not indicative of fluid volume deficit.
