Correct Answer: B

Rationale: The correct answer is 'Mania.' A client with a serum sodium level of 170 meq/L has hypernatremia, which can lead to manic behavior. Hypernatremia is associated with irritability, restlessness, confusion, and in severe cases, manic symptoms. Choices A, C, and D (Anger, Depression, Psychosis) are not typically associated with hypernatremia and are, therefore, incorrect in this context.

Correct Answer: A

Rationale: The correct answer is a history of radiation treatment in the neck region. Previous radiation to the neck may have damaged the parathyroid glands, which are crucial for calcium and phosphorus regulation. This damage can lead to disruptions in phosphorus levels, increasing the risk of hyperphosphatemia. Choices B, C, and D are not as directly related to phosphorus regulation. Orthopedic surgery, minimal physical activity, and food intake are more closely associated with calcium levels rather than phosphorus regulation. Therefore, it is essential for the nurse to focus on obtaining information about a history of radiation treatment in the neck region when assessing the risk of hyperphosphatemia in a client.

Correct Answer: B

Rationale: When educating clients with Schizophrenia nearing discharge, it is crucial to focus on teaching them how to recognize and manage symptoms of relapse. Clients are usually aware of these symptoms, such as feeling anxious and overwhelmed, before the onset of psychosis. This early stage is vital for intervention, which involves finding a safe environment, seeking help, avoiding stressors, and reducing stimuli. Understanding and managing relapse symptoms empower clients to take proactive steps in their care. Choices A and C are not as immediate and practical as recognizing symptoms of relapse for client safety and well-being. While contact with follow-up care is important, it is not as urgent and specific as knowing how to manage relapse symptoms for immediate intervention.

Correct Answer: A

Rationale: When providing care to a client with a cough, it is crucial to wear a mask to protect oneself from inhaling respiratory droplets containing infectious agents. The primary mode of transmission for coughs is through airborne droplets, making a mask the most appropriate choice to prevent the spread of respiratory infections. Gloves and gowns are more relevant when there is a risk of contact with bodily fluids, which is not the main concern with a cough. Shoe covers are not necessary in this scenario as the transmission of respiratory infections is not linked to footwear. Therefore, wearing a mask is the best choice to prevent airborne transmission and ensure the safety of the healthcare provider.

Correct Answer: A

Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.
