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. What is the primary purpose of administering IV fluids to a patient in septic shock?

• A. To reduce blood pressure.
• B. To increase cardiac output.
• C. To stabilize blood glucose levels.
• D. To maintain adequate tissue perfusion.

Correct answer: D

Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.

3. A client has just regained bowel sounds after undergoing surgery. The physician has prescribed a clear liquid diet for the client. Which of the following items should the nurse ensure is available in the client’s room before allowing the client to drink?

• A. Straw
• B. Napkin
• C. Oxygen saturation monitor
• D. Suction equipment

Correct answer: D

Rationale: After surgery, when a client has just regained bowel sounds and is prescribed a clear liquid diet, the nurse needs to consider the possibility of impaired swallow reflexes due to anesthesia effects, leading to an increased risk of aspiration. Despite checking the gag and swallow reflexes before offering fluids, having suction equipment readily available in the client's room is essential to manage any potential aspiration risk. Therefore, the correct answer is suction equipment (choice D). Choices A, B, and C are incorrect because while a straw, napkin, and oxygen saturation monitor may be useful in other situations, they are not directly related to managing the risk of aspiration associated with offering fluids to a client post-surgery.

4. A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?

• A. Check the client’s digoxin (Lanoxin) level.
• B. Administer an anti-nausea medication.
• C. Ask if the client can eat crackers.
• D. Refer the client to a gastrointestinal specialist.

Correct answer: A

Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.

5. The nurse is administering intravenous fluids to a dehydrated patient. On the second day of care, the patient's weight has increased by 2.25 pounds. The nurse would expect that the patient's fluid intake has

• A. equaled urine output.
• B. exceeded urine output by 1 L.
• C. exceeded urine output by 2.5 L.
• D. exceeded urine output by 3 L.

Correct answer: B

Rationale: A weight gain of 1 kg, or approximately 2.2 to 2.5 lb, is generally equivalent to 1 liter (L) of fluid retained by the body. In this case, the patient's weight gain of 2.25 pounds suggests an excess fluid retention of approximately 1 liter, indicating that the patient's fluid intake has exceeded urine output by 1 liter. Choices C and D are incorrect as they overestimate the fluid excess based on the patient's weight gain. Choice A is incorrect as it implies an exact balance between fluid intake and urine output, which is not reflected in the given weight increase.
