Exam Cram NCLEX RN Practice Questions
1. The nurse is taking an initial blood pressure reading on a 72-year-old patient with documented hypertension. How should the nurse proceed?
- A. Cuff should be placed on the patient's arm and inflated 30 mm Hg above the point at which the palpated pulse disappears.
- B. Cuff should be inflated to 200 mm Hg in an attempt to obtain the most accurate systolic reading.
- C. Cuff should be inflated 30 mm Hg above the patient's pulse rate.
- D. After confirming the patient's previous blood pressure readings, the cuff should be inflated 30 mm Hg above the highest systolic reading recorded.
Correct answer: C
Rationale: When measuring blood pressure, it's important to account for the possibility of an auscultatory gap, which occurs in about 5% of individuals, particularly those with hypertension due to a noncompliant arterial system. To detect an auscultatory gap, the cuff should be inflated 20 to 30 mm Hg beyond the point at which the palpated pulse disappears. This ensures an accurate measurement of blood pressure by overcoming the potential gap in sounds. Choice A is correct as it follows this guideline. Choices B and C are incorrect because inflating the cuff to 200 mm Hg or above the patient's pulse rate does not address the specific issue of an auscultatory gap. Choice D is incorrect as it focuses on the patient's previous readings rather than the current measurement technique needed to detect an auscultatory gap.
2. You see a sign over Mary Jones' bed when you arrive at 7 am to begin your day shift. The sign says, 'NPO'. Ms. Jones is on a regular diet. The patient asks for milk and some crackers. You _____________.
- A. can give her the milk but not the crackers
- B. can give her both the milk and the crackers
- C. can give her the crackers but not the milk
- D. cannot give her anything to eat or drink
Correct answer: D
Rationale: The correct answer is that you cannot give her anything to eat or drink. 'NPO' is the standard abbreviation for 'nothing by mouth,' indicating that the patient should not consume any food or liquids. It is crucial to adhere to this restriction to prevent any potential harm or complications in the patient's condition. Choices A, B, and C are incorrect because 'NPO' clearly specifies that the patient should not have anything to eat or drink, including milk and crackers. Providing these items could lead to adverse effects, so it is essential to follow the 'NPO' directive strictly.
3. Which of the following is recommended by Joint Commission guidelines regarding the use of restraints?
- A. Vest restraints should be used because they are the least restrictive type.
- B. Restraints should be used for 48 hours in non-psychiatric patients.
- C. Restraints should be applied to prevent wandering behavior.
- D. Alternative measures must be attempted first.
Correct answer: D
Rationale: When considering the use of restraints, Joint Commission guidelines emphasize the importance of attempting alternative measures before resorting to restraint application. This ensures that a comprehensive assessment is conducted and less restrictive interventions are explored. Using restraints solely based on their perceived level of restrictiveness, as stated in choice A, is not in line with the recommended approach. Restraints should not be used to manage wandering behavior, as indicated in choice C. Additionally, the statement in choice B regarding the duration of restraint use is inaccurate, as restraints on non-psychiatric patients should not exceed 24 hours according to The Joint Commission.
4. Rales and rhonchi are frequently noted during an examination of lung sounds. What is the difference between the two?
- A. Rales are louder.
- B. Rhonchi are noted only in infants.
- C. Rales occur on inspiration, rhonchi on expiration.
- D. Rales are noted only in infants.
Correct answer: C
Rationale: The correct answer is that rales occur on inspiration, while rhonchi occur on expiration. Rales are typically heard during inhalation when there is fluid in the alveoli or air passages. Rhonchi, on the other hand, are caused by air passing through obstructed airways during exhalation due to secretions in the respiratory tract. Choice A is incorrect because the loudness of the sounds is not the primary distinguishing factor between rales and rhonchi. Choice B is incorrect as rhonchi can be heard in individuals beyond infancy. Choice D is incorrect as rales can be present in patients of various age groups, not just infants.
5. Over a patient's lifespan, how does the pulse rate change?
- A. starts out fast and decreases as the patient ages.
- B. starts out slower and increases as the patient ages.
- C. varies from slow to fast throughout the lifespan.
- D. stays consistent from birth to death.
Correct answer: A
Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.
