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 healthcare professional is preparing to auscultate the abdomen. How should they proceed?
- A. Warm the endpiece of the stethoscope by rubbing it between their hands.
- B. Ensure the patient is adequately covered and comfortable during the examination.
- C. Ensure that the diaphragm side of the stethoscope is in use.
- D. Check the room temperature and offer blankets to the patient if needed.
Correct answer: D
Rationale: When preparing to auscultate the abdomen, it is important to ensure the patient's comfort. The room should be warm to prevent shivering, which can interfere with sound clarity. Offering blankets to the patient if they feel cold helps maintain their comfort during the examination. The endpiece of the stethoscope should be warmed by rubbing it between the examiner's hands, not by placing it in warm water. It is important to use the diaphragm, not the bell, of the stethoscope to auscultate for bowel sounds. Therefore, choice D is the correct answer, as it addresses the patient's comfort and the room temperature, which are essential for a successful abdominal auscultation.
3. Which technique is correct when assessing the radial pulse of a patient?
- A. Palpate for 1 minute if the rhythm is irregular.
- B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
- C. Palpate for 2 full minutes to detect any variation in amplitude.
- D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.
Correct answer: A
Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.
4. As a charge nurse, what is your primary responsibility for a 50-year-old blind and deaf patient admitted to your floor?
- A. Inform others about the patient's deficits.
- B. Communicate patient safety concerns to your supervisor.
- C. Provide continuous updates to the patient about the social environment.
- D. Provide a secure environment for the patient.
Correct answer: D
Rationale: The primary responsibility of the charge nurse for a blind and deaf patient is to provide a secure environment. Ensuring patient safety is crucial to prevent medical errors and adverse outcomes. By creating a safe environment, the nurse can protect the patient from harm and promote well-being. Option A is incorrect as the focus should be on ensuring patient safety rather than highlighting deficits. Option B is not the primary responsibility in this scenario, as the immediate concern is the patient's safety. Option C is irrelevant and does not address the patient's primary needs, which are safety and security.
5. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?
- A. Exercise
- B. Radiation
- C. Metabolism
- D. Food digestion
Correct answer: B
Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
