ATI PN Comprehensive Predictor 2024

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.

Correct Answer: A

Rationale: The correct answer is A: 'Apply counter-pressure for back pain.' Counter-pressure involves applying pressure to the lower back to alleviate pain during labor. This technique is a form of cutaneous stimulation, which can help with pain relief. Choice B, deep breathing exercises, is a form of relaxation technique and does not directly involve cutaneous stimulation. Choice C, visualizing the baby's head, is a mental imagery technique and does not involve physical stimulation of the skin. Choice D, massage therapy, is a tactile stimulation technique but is not specifically focused on back pain relief through counter-pressure.

Correct Answer: D

Rationale: The LPN should question the assignment of replacing the PCA pump cartridge and tubing as it is outside the LPN's scope of practice. LPNs are not trained to handle tasks related to PCA pumps, which involve medication administration and monitoring that are typically within the RN's responsibilities. Assisting a postop client with an incentive spirometer (Choice A), collecting a clean catch urine specimen (Choice B), and providing nasopharyngeal suctioning for a client with pneumonia (Choice C) are all tasks that fall within the LPN's scope of practice and do not require questioning by the LPN.

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: Limiting the intake of phosphorus-rich foods is appropriate for a client with chronic kidney disease. In individuals with chronic kidney disease, the kidneys cannot filter phosphorus effectively, leading to a buildup in the blood. This can result in bone and heart problems. Therefore, reducing phosphorus intake is crucial to prevent complications. Choices A, C, and D are incorrect. Increasing potassium intake may be harmful as potassium levels can accumulate in the blood with impaired kidney function. Encouraging protein-rich foods may not be suitable as excessive protein intake can strain the kidneys. Advising to increase fluid intake should be done cautiously as individuals with chronic kidney disease may need to restrict fluids based on their stage of the disease.
