How many cc are there in 25 ounces?
- A. 250
- B. 500
- C. 750
- D. 1000
Correct Answer: C
Rationale: To convert ounces to cc, we know that there are 30 cc in 1 ounce. Therefore, to find out how many cc are in 25 ounces, we multiply 30 cc/ounce by 25 ounces which equals 750 cc. This makes choice C, 750, the correct answer. Choices A, B, and D are incorrect as they do not correctly convert ounces to cc.

Patients who cannot move in their bed on their own should be turned at least ________________.
- A. once a day
- B. twice a day
- C. every 2 hours
- D. every 4 hours
Correct Answer: C
Rationale: Patients who are unable to move in bed are at high risk of developing pressure ulcers and skin breakdown due to prolonged pressure on specific body areas. Turning these patients at least every 2 hours is crucial to relieve pressure, improve circulation, and prevent skin damage. More frequent turning may be necessary for patients with specific needs, such as those who are incontinent of urine and require additional care. Turning patients less frequently, such as once a day, twice a day, or every 4 hours, increases the risk of developing pressure ulcers and other complications. Therefore, the correct answer is to turn patients who cannot move in their bed on their own every 2 hours.
A 1-month-old infant has a head measurement of 34 cm and a chest circumference of 32 cm. Based on the interpretation of these findings, what action would the nurse take?
- A. Refer the infant to a physician for further evaluation.
- B. Consider these findings normal for a 1-month-old infant.
- C. Expect the chest circumference to be greater than the head circumference.
- D. Ask the parent to return in 2 weeks to re-evaluate the head and chest circumferences.
Correct Answer: B
Rationale: In infants, a normal head measurement is approximately 32 to 38 cm, and it is usually around 2 cm larger than the chest circumference. These measurements vary with age; between 6 months and 2 years, both measurements are approximately the same, and after age 2 years, the chest circumference becomes greater than the head circumference. Given that the 1-month-old infant's head measurement is within the typical range and slightly larger than the chest circumference, the nurse should consider these findings normal. There is no indication to refer the infant for further evaluation or to have the parent return for re-evaluation in 2 weeks, as these measurements fall within the expected parameters for a 1-month-old infant.
When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?
- A. Notify the physician.
- B. Record this finding as normal.
- C. Check the child's blood pressure and note any variation with respiration.
- D. Document that this child has bradycardia and continue with the assessment.
Correct Answer: B
Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.
What technique would the nurse use to accurately assess a rectal temperature in an adult?
- A. Use a lubricated blunt tip thermometer.
- B. Insert the thermometer 2 to 3 inches into the rectum.
- C. Leave the thermometer in place for up to 8 minutes if the patient is febrile.
- D. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.
Correct Answer: A
Rationale: To accurately assess a rectal temperature in an adult, a nurse should use a lubricated rectal thermometer with a short, blunt tip. The thermometer is inserted only 2 to 3 cm (1 inch) into the rectum and left in place for 2 minutes. Choice B is incorrect as inserting the thermometer 2 to 3 inches would be too deep and inaccurate. Choice C is incorrect as leaving the thermometer in place for up to 8 minutes is unnecessary and can cause discomfort. Choice D is incorrect as smoking a cigarette does not impact rectal temperatures.
A triage nurse has four clients arrive in the emergency department within 15 minutes. Which client should the triage nurse send back to be seen first?
- A. A 2-month-old infant with a history of rolling off the bed and having a bulging fontanelle with crying
- B. A teenager who suffered singed facial hair while camping
- C. An elderly client with complaints of frequent liquid brown-colored stools
- D. A middle-aged client with intermittent pain behind the right scapula
Correct Answer: B
Rationale: The correct answer is the teenager who suffered singed facial hair while camping. This client is in the greatest danger with a potential risk of respiratory distress. Singed facial hair indicates exposure to heat or fire in close range, which could have caused serious damage to the interior of the lungs. It's crucial to prioritize this client as the interior lining of the lungs has no nerve fibers, so swelling may not be immediately noticeable. The other choices, while concerning, do not present an immediate life-threatening situation. The infant's condition may be serious but does not pose an immediate danger of respiratory distress. The elderly client's symptoms could indicate gastrointestinal issues, which are important but not as urgent as potential respiratory compromise. The middle-aged client's pain behind the right scapula, while uncomfortable, does not indicate an acute life-threatening condition requiring immediate attention.
