Exam Cram NCLEX RN Practice Questions

1. What technique would the nurse use to accurately assess a rectal temperature in an adult?

A. Use a lubricated blunt tip thermometer.
B. Insert the thermometer 2 to 3 inches into the rectum.
C. Leave the thermometer in place for up to 8 minutes if the patient is febrile.
D. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.

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.

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. What is a common error when taking a pulse?

A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
C. Counting the pulse for 15 seconds and multiplying the number by four.
D. None of the above will cause errors.

Correct answer: C

Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.

4. When assessing a pulse, what should be noted?

A. Rate
B. Rate and quality
C. Rate, quality, and fullness
D. Rate, quality, fullness, and regularity

Correct answer: C

Rationale: When assessing a pulse, it is important to note the rate (number of beats per minute), quality (regular or irregular), and fullness (thread and weak or full and bounding). These aspects provide crucial information about the patient's cardiovascular status. Regularity, as mentioned in option D, is not typically assessed during a pulse check and is not necessary for routine pulse assessment. Choice A is too limited as it overlooks important aspects beyond just the rate. Choice B improves by adding quality but still lacks the fullness aspect. Choice C is the most comprehensive and accurate as it includes all three essential aspects for a thorough pulse assessment.

5. Which of the following actions can help prevent a fire in the area where a healthcare professional works?

A. Using an adaptor when plugging in client equipment
B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
D. Keeping extra equipment stored in one area with other supplies and materials

Correct answer: C

Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.
