NCLEX RN Predictor Exam
1. When are manual hematocrits done?
- A. to monitor anemia
- B. by using a microhematocrit tube.
- C. to measure the percentage of plasma to cells.
- D. All of the above.
Correct answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
2. A client's intake and output are being calculated by a nurse. During the last shift, the client consumed � cup of gelatin, a skinless chicken breast, 1 cup of green beans, and 300 cc of water. The client also urinated 250 cc and had 2 bowel movements. What is this client's intake and output for this shift?
- A. 420 cc intake, 250 cc output
- B. 300 cc intake, 250 cc output
- C. 550 cc intake, 550 cc output
- D. 300 cc intake, 550 cc output
Correct answer: A
Rationale: The correct answer is 420 cc intake and 250 cc output for this shift. To calculate the intake, � cup of gelatin (approximately 120 cc) and 300 cc of water should be added together, resulting in 420 cc. Food intake like the chicken breast and green beans is not converted to cc's but may be documented for hospital protocol. Output includes urine (250 cc in this case) and other forms like vomit, diarrhea, or gastric suction. Bowel movements are not converted to cc's, but the nurse may need to document the number of stools passed. Choices B, C, and D are incorrect because they do not accurately reflect the intake and output calculations based on the information provided.
3. While measuring a patient's blood pressure, which factor influences a patient's blood pressure?
- A. Pulse rate
- B. Pulse pressure
- C. Vascular output
- D. Peripheral vascular resistance
Correct answer: D
Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.
4. What would be an appropriate evaluation statement for the nurse to write based on the client's ability to state only two signs of impaired circulation out of three as expected?
- A. Client understands the signs of impaired circulation
- B. Goal met: Client cited numbness and tingling as a sign of impaired circulation
- C. Goal not met: Client able to name only two signs of impaired circulation
- D. Goal not met: Client unable to describe signs of impaired circulation
Correct answer: C
Rationale: The appropriate evaluation statement for the nurse to write would be 'Goal not met: Client able to name only two signs of impaired circulation.' In this scenario, the client has only identified two out of the three signs of impaired circulation specified in the desired outcome. Therefore, the goal has not been fully achieved. It is essential in nursing practice to assess and document client progress accurately. While the client has shown some understanding by correctly identifying numbness and tingling as signs of impaired circulation, the inability to state the third sign indicates an incomplete achievement of the goal. This evaluation helps guide further interventions or educational strategies to help the client meet the desired outcome in the care plan.
5. The nurse is unable to palpate the right radial pulse on a patient. What would the nurse do next?
- A. Auscultate over the area with a fetoscope.
- B. Use a goniometer to measure the pulsations.
- C. Use a Doppler device to check for pulsations over the area.
- D. Check for the presence of pulsations with a stethoscope.
Correct answer: C
Rationale: When a nurse is unable to palpate a radial pulse, the next step is to use a Doppler device to check for pulsations over the area. Doppler devices are specifically designed to augment pulse or blood pressure measurements. Auscultating with a fetoscope is used to listen to fetal heart tones and is not relevant in this scenario. Goniometers are used to measure joint range of motion and are not used to assess pulses. Stethoscopes are primarily used to auscultate breath, bowel, and heart sounds, not to check for pulsations in peripheral pulses. Therefore, the correct course of action when unable to palpate a pulse is to utilize a Doppler device to assess for pulsations in the radial pulse area.
