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. The patient will begin taking doxycycline to treat an infection. When should the nurse plan to give this medication?

• A. 1 hour before or 2 hours after a meal.
• B. with an antacid to minimize GI irritation.
• C. with food to improve absorption.
• D. with small sips of water.

Correct answer: C

Rationale: Doxycycline is a lipid-soluble tetracycline that is better absorbed when taken with milk products and food. Taking doxycycline with food helps improve its absorption. It should not be taken on an empty stomach, as this can decrease its effectiveness. Antacids can interfere with the absorption of tetracyclines, so they should not be taken together. While it is important to stay hydrated when taking medications, small sips of water are not specifically recommended for doxycycline administration.

3. After a urography, a client is instructed by a nurse. Which instruction should the nurse include in this client’s discharge teaching?

• A. Avoid direct contact with your urine for 24 hours until the dye clears.
• B. You may experience dribbling of urine for several weeks post-procedure.
• C. Drink at least 3 liters of fluids today to assist in dye elimination.
• D. Your skin may turn slightly yellow from the dye used in this procedure.

Correct answer: C

Rationale: It is important for the client to increase fluid intake to aid in the rapid elimination of the potentially nephrotoxic dye used in urography. This instruction will help prevent any adverse effects related to the dye. Choices A, B, and D are incorrect because the dye used in urography is not radioactive, so there is no need to avoid direct contact with urine, urine dribbling is not a common post-procedure occurrence, and the dye should not cause the client's skin to change color.

4. When a patient starts taking amoxicillin, which foods should the nurse instruct the patient to avoid?

• A. Green leafy vegetables
• B. Beef and other red meat
• C. Coffee, tea, and colas
• D. Acidic fruits and juices

Correct answer: D

Rationale: The correct answer is D: Acidic fruits and juices. Amoxicillin can be irritating to the stomach, so avoiding acidic fruits and juices is recommended to reduce stomach discomfort or potential interactions. Green leafy vegetables (Choice A), beef and other red meat (Choice B), and coffee, tea, and colas (Choice C) are not typically contraindicated with amoxicillin. It is important to focus on acidic foods and beverages to promote comfort and effectiveness of the medication.

5. The nurse is taking the vital signs of a client after hemodialysis. Blood pressure is 110/58 mm Hg, pulse 66 beats/min, and temperature is 99.8°F (37.6°C). What is the most appropriate action by the nurse?

• A. Administer fluids to increase blood pressure.
• B. Check the white blood cell count.
• C. Monitor the client’s temperature.
• D. Connect the client to an electrocardiographic (ECG) monitor.

Correct answer: C

Rationale: After hemodialysis, it is crucial to monitor the client's temperature because the dialysate is warmed to increase diffusion and prevent hypothermia. The client's temperature might reflect the temperature of the dialysate. There is no need to administer fluids to increase blood pressure as the vital signs are within normal limits. Checking the white blood cell count or connecting the client to an ECG monitor is not necessary based on the information provided.
