ATI RN Comprehensive Exit Exam

Correct Answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.

Correct Answer: C

Rationale: Elevated serum creatinine levels indicate impaired kidney function. As kidney disease progresses, the kidneys are less able to filter waste products, leading to an increase in creatinine levels. Therefore, a high serum creatinine level of 2.5 mg/dL should be reported to the provider for further evaluation and management. Choices A, B, and D are within normal ranges and do not directly signify worsening kidney function in this context.

Correct Answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

Correct Answer: D

Rationale: The correct answer is D, dry mouth. Dry mouth is a common side effect of radiation therapy due to damage to the salivary glands. It is essential for the nurse to monitor for this condition as it can lead to oral health issues and discomfort. Fatigue (choice A) is a common side effect of radiation therapy, but in this case, dry mouth is a more specific side effect to monitor for. Hair loss (choice B) is more commonly associated with chemotherapy rather than radiation therapy. Nausea (choice C) is also a common side effect of radiation therapy, but dry mouth is a more direct effect of the treatment that the nurse should focus on monitoring.
