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.

Which of these guidelines would a healthcare professional follow when measuring a patient's weight?
- A. The patient is always weighed wearing only undergarments.
- B. The type of scale matters and should be consistent day to day.
- C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
- D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.
Correct Answer: D
Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.
A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these
actions is most appropriate when the nurse is assessing an infant's vital signs?
- A. The infant's radial pulse should be palpated, and the nurse should notice any
fluctuations resulting from activity or exercise. - B. The nurse should auscultate an apical rate for 1 minute and then assess for any
normal irregularities, such as sinus dysrhythmia.
- C. The infant's blood pressure should be assessed by using a stethoscope with a large
diaphragm piece to hear the soft muffled Korotkoff sounds. - D. The infant's chest should be observed and the respiratory rate counted for 1
minute; the respiratory pattern may vary significantly.
Correct Answer: B
Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be
counted by listening to the heart for 1 full minute to account for normal irregularities, such as sinus
dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently,
hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic
blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds.
An infant's respiratory rate should be assessed by observing the infant's abdomen, not chest, because
an infant's respirations are normally more diaphragmatic than thoracic. The nurse should auscultate
an apical heart rate, not palpate a radial pulse, with infants and toddlers.
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.
When preparing a patient on complete bed rest to eat, at what degree angle or more should you put the head of the bed up?
- A. 10
- B. 15
- C. 20
- D. 30
Correct Answer: D
Rationale: The correct answer is D: 30. When a patient is on complete bed rest, it is essential to elevate the head of the bed at a 30-degree angle or more before meals. This position helps prevent choking and aspiration of food during eating by promoting proper swallowing and digestion. Choices A, B, and C are incorrect because they do not provide the optimal elevation needed to support safe and effective feeding for a patient on complete bed rest.
What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?
- A. The popliteal artery should be auscultated to obtain thigh pressure.
- B. The best position to measure thigh pressure is the prone position.
- C. If the blood pressure in the arm is high in an adolescent, then it should be compared with the thigh pressure.
- D. Thigh pressure is generally higher than arm pressure due to the proximity to the heart and the size of the popliteal vessels.
Correct Answer: C
Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.
