A nurse is managing a patient's fluids and outputs over a shift. Here are the details:

0700: The nurse starts an IV of 0.45% Normal saline infusing at 100 mL/hr.

0900: The patient has coffee-ground emesis (vomit) measuring 300 mL.

1000: The nurse stops the IV of 0.45% Normal saline to administer an IV antibiotic. The antibiotic administered is Kefzol 1 g in 25 mL of D5W over 30 minutes.

1030: The antibiotic infusion stops, and the nurse resumes the IV fluid of 0.45% Normal saline at 100 mL/hr.

1100: The physician orders the insertion of an NG tube and intermittent suction. The nurse inserts the NG tube and connects it to intermittent suction.

1530: The patient voids another 350 mL and 200 mL. The nurse checks the NG tube canister and records the output for the shift as 300 mL.

Calculate the patient's total intake from 0700 to 1530.

Answer and Explanation

The Correct Answer is ["725"]

IV Fluid Intake:
- From 0700 to 0900: 2 hours × 100 mL/hr = 200 mL
- From 1030 to 1530: 5 hours × 100 mL/hr = 500 mL
- Total IV Fluid Intake: 200 mL + 500 mL = 700 mL
Antibiotic Infusion Intake:
- Antibiotic Solution: 25 mL
Total Intake Calculation:
- IV Fluid Intake: 700 mL
- Antibiotic Infusion: 25 mL
- Total Intake: 700 mL + 25 mL = 725 mL

Answer: The total intake for the patient from 0700 to 1530 is 725 mL.

Correct Answer is B

Explanation

The correct answer is B. Sanguinous. Sanguinous drainage is bright red, indicating fresh bleeding, and may be seen in the first few hours after surgery. Dark red drainage may indicate that there is an increase in bleeding, and the nurse should notify the provider immediately. Serosanguineous drainage is pink in color and consists of both blood and serum. Purulent drainage is thick, yellow or green in color and consists of pus, indicating an infection. Serous drainage is clear or light yellow in color and contains serum without red blood cells.

A. Positive air pressure holds the mouth open. B. Negative pressure holds airways closed. C. Delivery of oxygen facilitates expiratory effort. D. Alternating waves of air stimulate breathing.

Correct Answer is D

Explanation

The correct answer is choice D, alternating waves of air stimulate breathing. CPAP works by delivering a continuous stream of pressurized air through a mask, which is worn over the nose or nose and mouth while sleeping. This air pressure acts like a splint, holding the airway open and preventing it from collapsing during sleep. The alternating waves of air delivered by the CPAP machine help stimulate breathing, keeping the airway open and reducing the number of breathing pauses that occur during sleep. CPAP is a highly effective treatment for obstructive sleep apnea, a condition in which the airway becomes blocked during sleep, leading to breathing pauses and interrupted sleep. By keeping the airway open and stimulating breathing, CPAP helps to improve sleep quality, reduce daytime sleepiness, and improve overall health outcomes in people with sleep apnea.
