Correct Answer: A

Rationale: The correct action for the nurse to take is to prepare a new dose of insulin injection. Accidentally brushing the needle on a contaminated surface can lead to infection risk. Administering the insulin as it is or just wiping the needle with an alcohol swab would not be sufficient to eliminate the risk of infection. Asking the provider for guidance is not necessary in this situation as the nurse can independently take the appropriate action to ensure patient safety.

Correct Answer: B

Rationale: The correct intervention for a client with a chest tube connected to a closed drainage system is to maintain the drainage below the level of the chest. This position allows proper drainage of fluids and helps prevent complications such as backflow of blood or fluids into the chest cavity. Clamping the chest tube (Choice A) is incorrect as it can lead to a tension pneumothorax. Elevating the chest tube above chest level (Choice C) is also incorrect because it can impede proper drainage. Avoiding frequent dressing changes (Choice D) is important to prevent introducing infection, but it is not directly related to the position of the drainage system.

Correct Answer: B

Rationale: Instructing the client to administer insulin before meals is a crucial teaching point for a client with diabetes. This action ensures proper glucose management by helping to control blood sugar levels. Monitoring blood sugar levels once a week (Choice A) may not be frequent enough to manage diabetes effectively. While regular exercise (Choice C) is beneficial for glucose control, the immediate administration of insulin is more critical at the time of discharge. Administering oral hypoglycemics as needed (Choice D) is inappropriate as it does not address the need for insulin administration for a client being discharged.

Correct Answer: C

Rationale: When caring for a client diagnosed with delirium, the most important condition for the nurse to investigate is prescription drug intoxication. Delirium can be caused by various factors, and prescription drug intoxication is a common reversible cause. Investigating this factor first is crucial to identify and address the underlying cause promptly. Choices A, B, and D are less likely to be directly associated with delirium compared to prescription drug intoxication. While cancer, impaired hearing, and heart failure can have their complications and effects, they are not typically the primary causes of delirium in a client.

Correct Answer: A

Rationale: The correct answer is A: A history of gastroesophageal reflux disease. Clients with gastroesophageal reflux disease have a higher risk of aspiration during tube feeding due to the potential for reflux of stomach contents into the lungs. This increases the risk of aspiration pneumonia. Choices B, C, and D are incorrect. High osmolarity formulas may cause diarrhea but do not directly increase the risk of aspiration. Sitting in a high-Fowler's position actually reduces the risk of aspiration by promoting proper digestion and reducing the chance of regurgitation. A residual of 65 mL 1 hour postprandial is within an acceptable range and does not directly indicate a risk for aspiration.
