Correct Answer: B

Rationale: The correct answer is B: Decreased respiratory rate. In clients with COPD, especially when receiving oxygen therapy, a decreased respiratory rate is indicative of oxygen toxicity. This occurs because their respiratory drive is often dependent on low oxygen levels. Oxygen saturation of 94% is within an acceptable range and does not necessarily indicate oxygen toxicity. Wheezing is more commonly associated with airway narrowing or constriction, while peripheral cyanosis is a sign of decreased oxygen levels in the peripheral tissues, not oxygen toxicity.

Correct Answer: B

Rationale: Asking the client what the voices are saying is the priority action as it helps assess the content of the hallucinations. This assessment is crucial to determine if the client is at risk of harm to themselves or others. Encouraging the client to listen to music or providing a distraction may not address the underlying issues related to the hallucinations. Administering antipsychotic medication, although important, should come after a thorough assessment of the hallucinations to ensure the right medication and dosage are provided.

Correct Answer: D

Rationale: The vastus lateralis is the preferred site for IM injections in infants under 1 year of age because it is well developed and easily accessible compared to other muscle groups. The ventrogluteal and deltoid sites are not typically used for infants due to muscle development and size. The dorsogluteal site is not recommended for infants or young children due to its proximity to major nerves and blood vessels.

Correct Answer: A

Rationale: Measuring the client's abdominal girth daily is the most effective way to monitor the reduction of ascites and fluid retention in clients with liver cirrhosis. This measurement helps assess the effectiveness of treatment in managing ascites by monitoring changes in abdominal size. Monitoring the client's hemoglobin level (Choice B) is not directly related to assessing the effectiveness of ascites treatment. Administering lactulose as prescribed (Choice C) is important in managing hepatic encephalopathy, not ascites. Weighing the client weekly (Choice D) may not provide real-time feedback on the reduction of ascites compared to daily abdominal girth measurements.

Correct Answer: A

Rationale: The correct answer is A. Ibuprofen can increase the risk of bleeding when taken with warfarin, as both medications affect clotting. The client should use alternative pain relievers like acetaminophen. Choice B is correct as using an electric razor is a safe choice to prevent cuts that could lead to bleeding. Choice C is correct as warfarin interacts with vitamin K found in leafy green vegetables. Choice D is correct as regular blood level checks are necessary to monitor the effects and adjust the warfarin dosage if needed.
