A client is postoperative following hip replacement surgery. Which of the following instructions should the nurse include in preventing dislocation of the prosthesis?

Correct Answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.

Correct Answer: A

Rationale: For a patient with diarrhea, the priority is to manage dehydration by providing oral fluids and monitoring stool consistency. Option B suggesting administering antidiarrheal medications is not recommended as it may prolong the infection by preventing the body from expelling the infectious agent. Option C is incorrect because antibiotics are not routinely indicated for diarrhea unless there is a specific bacterial infection. Option D is not the most appropriate initial intervention for managing diarrhea since a low-fiber diet may not provide adequate nutrition for the patient or help resolve the underlying cause of diarrhea.

Correct Answer: B

Rationale: The correct answer is to limit phosphorus and potassium intake for a client with chronic kidney disease. In renal insufficiency, the kidneys struggle to excrete these minerals, leading to their buildup in the blood, which can be harmful. Limiting phosphorus and potassium intake helps prevent further kidney damage and manage the progression of chronic kidney disease. Encouraging protein-rich foods (Choice C) may be counterproductive as excessive protein intake can burden the kidneys. Increasing potassium-rich foods (Choice A) is incorrect as high potassium levels can be detrimental in kidney disease. Increasing calcium-rich foods (Choice D) is not typically a focus in dietary teaching for chronic kidney disease unless there is a specific deficiency or need, as excessive calcium intake can also be harmful to kidney function.

Correct Answer: B

Rationale: Irrigating the bladder using sterile technique is crucial in the care of a client following a transurethral resection of the prostate (TURP). This intervention helps prevent infection and maintains patency of the urinary catheter, promoting healing. Administering antibiotics (Choice A) may be necessary if there is an infection present, but it is not a routine intervention following TURP. Avoiding bladder irrigation (Choice C) is not recommended as it can lead to clot retention and other complications. Inserting a urinary catheter (Choice D) is usually already done during the TURP procedure and is not a postoperative intervention.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, the primary concern is ensuring an adequate oxygen supply to the body. By administering oxygen, you can help improve oxygenation, which is crucial for the patient's overall well-being. Assessing airway patency is important but administering oxygen takes precedence as it directly addresses the oxygenation concern. Monitoring oxygen saturation is also essential, but the immediate action should be to provide oxygen. Calling for assistance can be important but is not the first priority when dealing with a patient in respiratory distress.

Correct Answer: C

Rationale: The most appropriate position for a client post-lumbar puncture is the supine position. Placing the client in a supine position helps prevent spinal headaches by allowing the puncture site to seal effectively and reducing the risk of cerebrospinal fluid leakage. High Fowler's position, prone position, and sitting position are not recommended after a lumbar puncture as they may increase the risk of complications like spinal headaches.

Correct Answer: A

Rationale: When assessing and managing a patient with a suspected UTI, the priority is to start antibiotic therapy to treat the infection. Antibiotics are crucial in eliminating the bacteria causing the UTI. While hydration is important to help flush out the bacteria, pain management can help alleviate discomfort but is not the primary treatment. Patient education is vital for prevention and management but is not the immediate intervention required for a suspected UTI.

Correct Answer: A

Rationale: The correct action for the nurse to take after administering an influenza virus immunization by the intradermal route is to avoid massaging the site. Massaging the site can spread the vaccine, potentially reducing its effectiveness. Rubbing the site in a circular motion or applying a bandage are not recommended actions as they can also interfere with the proper absorption of the vaccine.

Correct Answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.
