Correct Answer: B

Rationale: The correct action for the nurse to take when noticing a discrepancy between the client's current IV infusion and the information received during the shift report is to compare the current infusion with the prescription in the client's medication record. This step is crucial to ensure the accuracy of the prescribed treatment and to prevent any potential harm to the client. Option A is incorrect because completing an incident report should only be done after verifying the discrepancy. Option C is incorrect as contacting the charge nurse should come after confirming the details. Option D is incorrect as submitting a written warning is not appropriate without verifying the information first.

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: 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: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.

Correct Answer: B

Rationale: The correct first step before administering a blood transfusion is to verify that the client's blood type matches the blood product. This step is crucial to prevent transfusion reactions due to incompatibility. Choice A is incorrect because blood should not be administered through an IV push for a blood transfusion. Choice C is incorrect because it is not necessary for the client to eat before a blood transfusion. Choice D is incorrect because administering a diuretic is not a standard practice before starting a blood transfusion.
