NCLEX RN Predictor Exam
1. When are manual hematocrits done?
- A. to monitor anemia
- B. by using a microhematocrit tube.
- C. to measure the percentage of plasma to cells.
- D. All of the above.
Correct answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
2. Who is legally able to make decisions for the patient or resident during a patient care conference when the patient is not mentally able to make decisions on their own?
- A. The patient or their healthcare proxy
- B. Only the patient
- C. Only the healthcare proxy
- D. The doctor
Correct answer: C
Rationale: When a patient is unable to make decisions due to mental incapacity, the healthcare proxy, designated by the patient in advance, has the legal authority to make decisions on the patient's behalf. In this situation, the patient lacks the capacity to make decisions independently. The healthcare proxy's role is to represent the patient's wishes and best interests. The doctor's role in a patient care conference is to provide medical expertise, offer recommendations, and assist in the decision-making process, but the final decision-making authority lies with the healthcare proxy, not the doctor.
3. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?
- A. Controls stray electrical currents.
- B. Promotes efficient use of electricity.
- C. Shuts off the appliance if there is an electrical surge.
- D. Divides the electricity among the appliances in the room.
Correct answer: A
Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.
4. Which of the following is part of client teaching regarding antiembolism stockings?
- A. Instruct the client to roll the top portion of the stocking down if it is too long
- B. Stockings are applied with the toes uncovered at the end
- C. Measure for thigh-high stockings from the foot to the knee
- D. Stockings are to be smooth from end to end without wrinkles
Correct answer: D
Rationale: When educating clients about antiembolism stockings, it is essential to emphasize that the stockings should be smooth from end to end without wrinkles. Wrinkles in the stockings can impede circulation, defeating the purpose of wearing them to prevent blood clot formation. Instructing the client to roll the top portion of the stocking down if it is too long (Choice A) is incorrect as it can create unnecessary pressure points. Stockings should be applied with the toes covered at the end (Choice B) to ensure proper compression. Measuring for thigh-high stockings should be done from the knee to the foot (Choice C) to ensure the correct fit and compression gradient.
5. A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?
- A. Ask the parent to place the child on the examining table.
- B. Have the parent remove all of the child's clothing before the examination.
- C. Allow the child to keep a security object such as a toy or blanket during the examination.
- D. Initially focus the interactions on the child, essentially ignoring the parent until the child's trust has been obtained.
Correct answer: C
Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
