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: Immobility and decreased lung function. Older adults with immobility and decreased lung function are at a higher risk of developing pneumonia. Immobility can lead to decreased lung expansion and impaired clearance of secretions, predisposing to pneumonia. While poor hygiene, aspiration, use of respiratory equipment, medications, poor nutritional status, and compromised immune system can also contribute to pneumonia risk, they are not as directly associated with pneumonia in older adults as immobility and decreased lung function.

Correct Answer: A

Rationale: The correct answer is A: Shortness of breath and weight gain. Early signs of heart failure typically manifest as shortness of breath due to fluid accumulation in the lungs and weight gain due to fluid retention in the body. Choices B, C, and D are incorrect. Fatigue and chest pain are symptoms commonly associated with heart conditions but are not specific early signs of heart failure. Nausea and vomiting are not typically early signs of heart failure. Cough can be a symptom of heart failure, but it is usually associated with other symptoms like shortness of breath rather than being an isolated early sign. Elevated blood pressure is not an early sign of heart failure; in fact, heart failure is more commonly associated with low blood pressure.

Correct Answer: A

Rationale: Creatinine is the correct answer. In acute kidney injury, creatinine levels are expected to be elevated due to impaired renal function. Magnesium, hemoglobin, and white blood cell count are not typically elevated in acute kidney injury. Magnesium levels may be affected in kidney disease, but elevation is not a common finding in acute kidney injury.

Correct Answer: D

Rationale: The correct answer is to keep the cord stump dry until it falls off. This is important to promote natural healing and prevent infection. Choice A is incorrect because cleaning the cord with hydrogen peroxide daily can actually delay healing and increase the risk of infection. Choice B is incorrect as the cord stump typically falls off within 1 to 3 weeks, not in 5 days. Choice C is incorrect because a cord stump turning black is a normal part of the healing process and does not necessarily indicate a problem requiring immediate provider contact.
