Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

Correct Answer: A

Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.

Correct Answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm�) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

Correct Answer: B

Rationale: The correct sequence for administering a large volume enema is as follows: 1. Insert the enema tube into the rectum, 2. Administer the enema solution, 3. Clamp the tube, 4. Remove the tube, 5. Wrap the end with tissue. Therefore, the nurse should remove the enema tube from the client's rectum after administering the enema solution. Choices A, C, and D are incorrect because the enema tube should be removed from the rectum after the administration of the solution, not before or during the process.

Correct Answer: C

Rationale: The correct answer is C. Taking water pills (diuretics) only when feeling short of breath is incorrect. Diuretics should be taken regularly as prescribed to help manage fluid retention in chronic heart failure. This statement indicates a need for further teaching as the client needs to understand the importance of consistent medication adherence. Choices A, B, and D demonstrate good understanding of self-care management in heart failure, including daily weight monitoring, prompt reporting of worsening symptoms to the healthcare provider, and dietary sodium restriction, respectively.
