NCLEX RN Predictor Exam
1. What is the BEST blood collection location for a newborn?
- A. the AC
- B. the veins of the forehead
- C. the heel
- D. the fingertips
Correct answer: C
Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.
2. A client with expressive aphasia is pointing wildly at the bath water but unable to speak. Which response from the nurse is most appropriate?
- A. Is something wrong with the bath water?
- B. Just calm down, we'll finish your bath soon.
- C. Are you trying to tell me something?
- D. Shall I turn on the television?
Correct answer: A
Rationale: A client with expressive aphasia faces difficulty expressing themselves verbally but can understand others. In this scenario, the client's gestures indicate a communication attempt. The nurse's best response is to directly address the potential issue the client is indicating, which is the bath water. Option A acknowledges the client's non-verbal communication and seeks to address their concern. Choices B, C, and D do not directly address the client's attempt to communicate about the bath water, which is the focal point of the interaction.
3. A patient is asked to abduct her arms. Which of the following accurately describes her arm movement?
- A. She moves her arms away from her trunk
- B. She moves her arms toward her trunk
- C. She rotates her arms at the wrists while holding them away from her body
- D. She crosses her arms over her abdomen
Correct answer: A
Rationale: Abduction refers to moving a body part away from the midline of the body. In this case, when the patient abducts her arms, she is moving them away from her trunk. Choice A is correct. Choices B, C, and D are incorrect. Choice B describes adduction, which is the movement of a body part toward the midline. Choice C describes wrist rotation, not arm abduction. Choice D describes crossing the arms over the abdomen, which is not the movement associated with abduction.
4. A patient's body temperature has varied over the last 24 hours from 97.6 degrees F in the morning to 99 degrees F in the evening. The patient is worried that this change in temperature may indicate the beginning of a fever. Which of the following BEST explains this phenomenon?
- A. The patient definitely has a fever in the evening and should be seen by a doctor.
- B. The patient is experiencing changes related to a diurnal rhythm.
- C. The patient is more than likely taking their temperature incorrectly.
- D. The patient is experiencing changes related to fluctuating daily hormones.
Correct answer: B
Rationale: The patient is experiencing changes related to a diurnal rhythm. Diurnal rhythm is the phenomenon of body temperature fluctuating depending on the time of day. Temperatures taken in the morning are typically lower than those taken throughout the rest of the day. Choice A is incorrect because a single elevated temperature reading in the evening does not definitively indicate a fever. Choice C is incorrect as there is no indication of incorrect temperature measurement. Choice D is incorrect as the temperature changes are not related to monthly hormones but rather to the body's natural daily rhythm.
5. What does preload refer to?
- A. The volume of blood entering the left side of the heart
- B. The volume of blood entering the right side of the heart
- C. The pressure in the venous system that the heart must overcome to pump the blood
- D. The pressure in the arterial system that the heart must overcome to pump the blood
Correct answer: B
Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.
