Exam Cram NCLEX RN Practice Questions
1. What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?
- A. The popliteal artery should be auscultated to obtain thigh pressure.
- B. The best position to measure thigh pressure is the prone position.
- C. If the blood pressure in the arm is high in an adolescent, then it should be compared with the thigh pressure.
- D. Thigh pressure is generally higher than arm pressure due to the proximity to the heart and the size of the popliteal vessels.
Correct answer: C
Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.
2. Which nursing intervention is most appropriate to reduce environmental stimuli that may cause discomfort for a client?
- A. Loosen pressure dressings on wounds
- B. Use assistance to lift a client in bed
- C. Check temperature of water used in a sponge bath
- D. Position the client in a prone position
Correct answer: C
Rationale: To reduce environmental stimuli that may cause discomfort for a client, nurses can implement various interventions. Checking the temperature of the water used in a sponge bath is crucial to prevent burns from water that is too hot or discomfort from water that is too cold. This intervention addresses a common source of discomfort for clients during personal care. Loosening pressure dressings on wounds, although important for wound care, does not directly address environmental stimuli. Using assistance to lift a client in bed is about proper positioning and preventing injury rather than reducing environmental stimuli. Positioning the client prone is not a suitable intervention for reducing discomfort caused by environmental stimuli.
3. What does the term 'Afferent Nerve' mean?
- A. Carrying an impulse to the brain
- B. Carrying an impulse away from the brain
- C. Carrying impulses to the motor neurons of the appendicular muscles
- D. None of the above
Correct answer: A
Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'
4. When turning an immobile bedridden client without assistance, which action by the nurse best ensures client safety?
- A. Securely grasp the client's arm and leg.
- B. Put bed rails up on the side of bed opposite from the nurse.
- C. Correctly position and use a turn sheet.
- D. Lower the head of the client's bed slowly
Correct answer: B
Rationale: When turning an immobile bedridden client without assistance, the best action to ensure client safety is to put bed rails up on the side of the bed opposite from the nurse. This is important because the nurse can only stand on one side of the bed, so having bed rails on the opposite side prevents the client from falling out of bed. Option A, which suggests securely grasping the client's arm and leg, can potentially cause client injury to the skin or joints. Options C and D, correctly positioning and using a turn sheet, and lowering the head of the client's bed slowly, respectively, are useful techniques during client turning but are of lower priority in terms of safety compared to the use of bed rails.
5. Each small square on the EKG paper is:
- A. 0.04 seconds long and 5mm tall
- B. 0.2 seconds long and 5mm tall
- C. 0.04 seconds long and 20mm tall
- D. 0.04 seconds long and 1mm tall
Correct answer: D
Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.
