Nursing Elites

1. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?

• A. Cardiac output.
• B. Right atrial blood flow.
• C. Left end-diastolic pressure.
• D. Cardiac index.

Correct answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

2. A nurse is assessing a postoperative client on an hourly basis. The nurse notes that the client’s urine output for the past hour was 25 mL. Based on this finding, the nurse first:

• A. Calls the physician
• B. Increases the rate of the IV infusion
• C. Checks the client’s overall intake and output record
• D. Administers a 250-mL bolus of normal saline solution (0.9%)

Correct answer: C

Rationale: Clients are at risk of hypovolemia postoperatively, and decreased urine output can be an early sign. However, to accurately interpret this finding, the nurse must assess the overall fluid balance by checking the client’s intake and output records. Increasing the IV infusion rate or administering a bolus of normal saline solution without a physician's order would not be appropriate as these interventions require a prescription. The physician should be notified once the nurse has collected all necessary assessment data, including fluid status and vital signs.

3. The nurse is assessing a client with a diagnosis of pre-renal acute kidney injury (AKI). Which condition would the nurse expect to find in the client’s recent history?

• A. Pyelonephritis
• B. Myocardial infarction
• C. Bladder cancer
• D. Kidney stones

Correct answer: B

Rationale: In pre-renal acute kidney injury, there is a decrease in perfusion to the kidneys. Myocardial infarction can lead to decreased blood flow to the kidneys, causing pre-renal AKI. Pyelonephritis is an intrinsic/intrarenal cause of AKI involving kidney damage. Bladder cancer and kidney stones are post-renal causes of AKI due to urinary flow obstruction, not related to perfusion issues seen in pre-renal AKI.

4. The nurse empties the nasogastric suction collection canister of a client who had a bowel resection the previous day and notes that 1000 ml of gastric secretions were collected in the last 4 hours. What condition is the client at risk for developing?

• A. Metabolic alkalosis
• B. Hyperkalemia
• C. Metabolic acidosis
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Metabolic alkalosis. Loss of gastric secretions, which contain stomach acid, can lead to metabolic alkalosis. Excessive loss of acid results in an increase in the blood pH, leading to alkalosis. Hyperkalemia (B) is an elevated potassium level and is not directly related to the loss of gastric secretions. Metabolic acidosis (C) is an acid-base imbalance characterized by low pH and bicarbonate levels, which is the opposite of what would occur with the loss of gastric secretions. Hypoglycemia (D) is low blood sugar and is not typically associated with the scenario described in the question.

5. The nurse is assessing an older adult with a pacemaker who leads a sedentary lifestyle. The client reports being unable to perform activities that require physical exertion. The nurse should further assess the client for which of the following?

• A. Left ventricular atrophy.
• B. Irregular heartbeats.
• C. Peripheral vascular occlusion.
• D. Pacemaker function.

Correct answer: A

Rationale: The correct answer is A: Left ventricular atrophy. Older adults who lead sedentary lifestyles are at risk of developing left ventricular atrophy, which can lead to decreased cardiac output during physical exertion. This condition can contribute to the client's inability to perform activities requiring physical exertion. Choice B, irregular heartbeats, may be a consideration due to the presence of a pacemaker, but the client's reported inability to perform physically exerting activities is more indicative of a structural issue like left ventricular atrophy rather than a rhythm-related problem. Peripheral vascular occlusion (Choice C) is less likely to be the cause of the client's symptoms compared to the cardiac-related issue of left ventricular atrophy. While assessing pacemaker function (Choice D) is important, the client's symptoms are more suggestive of a cardiac structural issue rather than a malfunction of the pacemaker.
