Correct Answer: C

Rationale: Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.

Correct Answer: C

Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.

Correct Answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

Correct Answer: B

Rationale: The correct answer is B: Positioning the client in the prone position. Placing the client in the prone position should be avoided in a client with increased intracranial pressure (ICP) as it can further raise ICP. The prone position can hinder venous return and increase pressure within the cranial vault, potentially worsening the client's condition. Keeping the head of the bed elevated at 30 degrees helps promote venous drainage and reduce ICP. Placing the client in a lateral recumbent position can also assist in reducing ICP by optimizing cerebral perfusion. Elevating the client's legs can help improve venous return and maintain adequate cerebral blood flow, making it a suitable positioning intervention for managing increased ICP.

Correct Answer: D

Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.
