Correct Answer: A

Rationale: Administering oxygen is the primary nursing action for a patient with confusion post-surgery because it helps address any potential hypoxia that may be contributing to the patient's confusion. While repositioning the patient, monitoring vital signs, and checking oxygen saturation are important nursing interventions, administering oxygen takes precedence in ensuring adequate oxygenation levels, which is crucial in managing post-surgery confusion.

Correct Answer: D

Rationale: The correct answer is to recheck blood sugar levels in 15 minutes. This intervention is crucial to ensure that the hypoglycemia has been effectively corrected after the initial treatment. Administering IV fluids may be necessary in cases of severe dehydration but is not the primary intervention for hypoglycemia. Checking blood sugar levels is important, but the primary intervention should focus on treating the low blood sugar levels first, which is done by providing oral glucose. However, the most critical step after providing initial treatment is to recheck blood sugar levels to confirm that they have improved to safe levels.

Correct Answer: D

Rationale: Spinach is an excellent choice to recommend as it is rich in non-heme iron, which can help improve iron levels in clients with iron deficiency anemia. Eggs (Choice A) are a good source of protein but do not contain as much iron as spinach. Carrots (Choice B) are rich in vitamin A but are not a significant source of iron. White bread (Choice C) is not a good source of iron compared to spinach.

Correct Answer: A

Rationale: The correct answer is to monitor serum creatinine. In patients with chronic kidney disease, monitoring serum creatinine is crucial as it reflects kidney function. This assessment helps healthcare providers in evaluating the progression of the disease and adjusting treatment plans accordingly. Monitoring blood pressure (choice B) is essential in managing chronic kidney disease, but monitoring serum creatinine takes precedence. Monitoring urine output (choice C) and potassium levels (choice D) are also important aspects of managing chronic kidney disease, but they are not the priority assessment compared to monitoring serum creatinine.

Correct Answer: D

Rationale: The correct answer is D because consuming more simple carbohydrates when blood glucose levels are low can cause a rapid spike in blood sugar levels, leading to potential complications. Clients with type 2 diabetes should eat complex carbohydrates or foods that help stabilize blood sugar levels when experiencing hypoglycemia. Choices A, B, and C demonstrate understanding of monitoring blood glucose levels regularly, not stopping insulin without consulting a healthcare provider, and adhering to insulin therapy even when feeling well, which are all appropriate actions for managing diabetes.
