NCLEX RN Predictor Exam

1. Digestion, elimination, and ___________ are the three functions of the digestive system.

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

2. What is the primary purpose of emergency planning?

Correct answer: D

Rationale: The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.

3. What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?

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.

4. A client has become combative and is attempting to pull out his IV and take off his surgical dressings. The nurse receives an order to apply wrist restraints. Which action of the nurse signifies that restraints are being used safely?

Correct answer: C

Rationale: Restraint use must prioritize the safety of the client. When applying restraints around the wrists, the padded side should be placed against the skin to help prevent skin breakdown. Additionally, restraints should be secured in quick-release knots to ensure they can be removed rapidly in case of an emergency. Choice A is incorrect as restraints should not be tied in a way that could prevent quick removal. Choice B is incorrect because restraints should not be attached to a movable part of the bed to avoid unintentional movement. Choice D is incorrect as assessing distal circulation is important but is not directly related to the safe application of restraints.

5. Which is the most effective action for controlling the spread of infection?

Correct answer: A

Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.
