Exam Cram NCLEX RN Practice Questions Questions
Question 1 of 5
When evaluating the temperature of older adults, what aspect should the healthcare provider remember about an older adult's body temperature?
Correct Answer: A
Rationale: When evaluating the temperature of older adults, it is important to note that their body temperature is usually lower than that of younger adults, with a mean temperature of 36.2°C. Choice B is incorrect because an older adult's body temperature is not approximately the same as that of a young child. Choice C is incorrect because body temperature is a physiological parameter and does not vary based on the type of thermometer used. Choice D is incorrect because while older adults may have less effective heat control mechanisms, their body temperature is typically lower, not widely fluctuating.
Question 2 of 5
What technique would the nurse use to accurately assess a rectal temperature in an adult?
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.
Question 3 of 5
Which technique is correct when assessing the radial pulse of a patient?
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.
Question 4 of 5
When assessing a patient's pulse, which of the following characteristics would the nurse also notice?
Correct Answer: A
Rationale: When assessing a patient's pulse, the nurse should observe characteristics such as rate, rhythm, and force. Force refers to the strength or amplitude of the pulse, which provides important information about cardiac output. Pallor is the paleness of the skin and is not directly related to pulse assessment. Capillary refill time is used to assess peripheral perfusion and is not specifically part of pulse assessment. Timing in the cardiac cycle is a broader concept and not a characteristic directly assessed during a pulse examination. Therefore, choice A, 'Force,' is the correct answer as it aligns with the standard parameters evaluated during pulse assessment.
Question 5 of 5
When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?
Correct Answer: B
Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.
