manual hematocrits are done

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. One major difference between long term care and respite centers is the fact that long term care facilities:

A. provide both physical and emotional care on an ongoing basis, while respite centers offer only temporary services.
B. provide care for residents on a long-term basis, while respite centers offer only outpatient services.
C. provide care for residents on a long-term basis, while respite centers offer only temporary services.
D. There is no difference. Long-term care and respite care are the same.

Correct answer: C

Rationale: The major difference between long-term care and respite centers is that long-term care facilities provide both physical and emotional care on an ongoing, long-term basis. This continuous care is essential for residents who require extended assistance. In contrast, respite centers offer temporary services, providing similar care but for a short-term duration. These short-term services are designed to give family caregivers a break from their daily responsibilities. Choice A is incorrect because both long-term care and respite centers can offer both physical and emotional care, but the key distinction lies in the duration of care provided. Choice B is incorrect as respite centers do not typically offer outpatient services, and the focus is on temporary relief rather than long-term care. Choice D is incorrect as the question clearly highlights a major difference between long-term care and respite centers.

3. In which situation would the nurse use bimanual palpation technique?

A. Palpating the thorax of an infant
B. Palpating the kidneys and uterus
C. Assessing pulsations and vibrations
D. Assessing the presence of tenderness and pain

Correct answer: B

Rationale: Bimanual palpation involves using both hands to envelop or capture specific body parts or organs like the kidneys, uterus, or adnexa. This technique is particularly useful for assessing the size, shape, consistency, and mobility of deep organs like the kidneys and uterus. Palpating the thorax of an infant (Choice A) is usually done with a different technique like gentle, single-handed palpation. Assessing pulsations and vibrations (Choice C) and assessing tenderness and pain (Choice D) typically do not require the use of bimanual palpation, making Choices A, C, and D incorrect.

4. A student is late for an appointment and has rushed across campus to the health clinic. How should the nurse proceed?

A. Allow 5 minutes for the student to relax and rest before checking their vital signs.
B. Check the blood pressure in both arms, expecting a difference in the readings due to the recent exercise.
C. Immediately monitor the student's vital signs upon arrival at the clinic and then 5 minutes later, recording any differences.
D. Check the student's blood pressure in the supine position to provide a more accurate reading and allow the student to relax at the same time.

Correct answer: A

Rationale: To ensure an accurate blood pressure reading, it is important for the student to be in a relaxed state. Allowing at least a 5-minute rest period helps reduce anxiety and provides a valid blood pressure measurement. Checking the blood pressure in both arms is unnecessary unless there is a specific reason to suspect an issue, and recent exercise should not significantly impact the readings. Monitoring vital signs immediately upon arrival may not yield accurate results due to the rush and anxiety of the student. Checking blood pressure in the supine position is not necessary in this scenario and does not provide a more accurate reading.

5. A 6-month-old infant has been brought to the well-child clinic for a checkup. The infant is currently sleeping. What would the nurse do first when beginning the examination?

A. Wake the infant before beginning the examination.
B. Examine the infant's hips before the infant wakes up.
C. Auscultate the lungs and heart while the infant is still sleeping.
D. Begin with the assessment of the eye and continue with the remainder of the examination in a head-to-toe approach.

Correct answer: C

Rationale: When the infant is quiet or sleeping, it is an ideal time to assess the cardiac, respiratory, and abdominal systems. It is recommended not to wake the infant unnecessarily. Auscultating the lungs and heart while the infant is still sleeping allows for a comprehensive assessment without disturbing the infant. Examining the infant's hips prematurely may disrupt the infant's sleep. Starting with an assessment of the eye is not appropriate as it is an invasive procedure and should be performed towards the end of the examination after the non-invasive assessments have been completed.
