ATI Exit Exam RN

Correct Answer: A

Rationale: In patients with heart failure, monitoring daily weight is the most accurate method for assessing fluid balance. Weight gain can indicate fluid retention, a common issue in heart failure patients. Monitoring input and output (B) is essential but may not always accurately reflect fluid balance. Checking for edema (C) is important as it can indicate fluid accumulation, but daily weight monitoring is more precise. Monitoring blood pressure (D) is important in heart failure management but does not directly assess fluid balance.

Correct Answer: A

Rationale: The best method to monitor fluid balance in a patient receiving diuretics is to monitor daily weight. Daily weighing is a precise way to assess changes in fluid status as it reflects variations in total body water. Monitoring intake and output (choice B) is also important but may not provide as accurate a measurement as daily weight. Monitoring blood pressure (choice C) is essential but does not directly measure fluid balance. Monitoring edema (choice D) is helpful to assess fluid status visually but may not be as sensitive as daily weight measurements in detecting subtle changes in fluid balance.

Correct Answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

Correct Answer: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

Correct Answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.
