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. The nurse suspects that a client is withholding health-related information out of fear of discovery and possible legal problems. The nurse formulates nursing diagnoses for the client carefully, being concerned about a diagnostic error resulting from which of the following?
- A. Incomplete data
- B. Generalizing from experience
- C. Identifying with the client
- D. Lack of clinical experience
Correct answer: A
Rationale: In this scenario, the nurse is cautious about potential diagnostic errors due to incomplete data. When a client withholds information, it can lead to incomplete data, which may result in inaccurate nursing diagnoses and care planning. Therefore, the nurse's primary concern is collecting accurate data to make informed clinical decisions. Choices B, C, and D are not relevant to the situation described. Generalizing from experience, identifying with the client, and lack of clinical experience do not directly address the issue of incomplete data impacting the diagnostic process.
3. Nursing care plans are _______________?
- A. written by CNAs before they provide care
- B. guidelines of care that all nursing team members use
- C. used by nurses but not by nursing assistants
- D. used by nursing assistants but not by nurses
Correct answer: B
Rationale: Nursing care plans are comprehensive documents created by registered nurses to outline individualized care for patients. These plans serve as guidelines for all members of the nursing team, including nursing assistants, to ensure consistent and quality care. Choice A is incorrect as CNAs typically assist in implementing the care plan rather than creating it. Choice C is incorrect as nursing care plans are utilized by all members of the nursing team, not exclusive to only nurses. Choice D is incorrect as nursing assistants also utilize nursing care plans to provide patient care effectively.
4. Which of the following vital signs can be expected in a child that is afebrile?
- A. Rectal Temp of 100.9 degrees F.
- B. Oral Temp of 38 degrees C.
- C. Axillary Temp of 98.6 degrees F.
- D. All of the above are incorrect.
Correct answer: C
Rationale: The correct answer is the axillary temperature of 98.6 degrees F. Afebrile means without a fever, and an axillary temperature, which is taken in the armpit, is considered normal at 98.6 degrees F. Choice A is incorrect as a rectal temperature of 100.9 degrees F indicates a fever. Choice B is incorrect as an oral temperature of 38 degrees C is also indicative of a fever. Choice D is incorrect as not all options are wrong; only choices A and B are incorrect for an afebrile child.
5. Improper placement of the hands under the rib cage when performing the Heimlich maneuver could result in:
- A. damage to the manubrium of the sternum.
- B. damage to the xiphoid process.
- C. damage to the coccyx.
- D. None of the above is possible, even with improper hand placement.
Correct answer: B
Rationale: The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum. Placing the hands improperly during the Heimlich maneuver too close to this process can result in it breaking off and potentially causing damage to internal organs. Choices A and C are incorrect because the manubrium of the sternum and the coccyx are not in the area where the hands would typically be placed during the Heimlich maneuver.
