Question 1 of 5
Which of the following tests would MOST LIKELY be performed on a patient who is being monitored for coagulation therapy?
Correct Answer: A
Rationale: The correct answer is A: PT/INR. Prothrombin times (PT/INR) are commonly used to monitor patients on Coumadin (warfarin) therapy, an anticoagulant that slows the blood's ability to clot. Monitoring PT/INR levels helps ensure the patient is receiving the appropriate dosage of Coumadin.
Choice B, CBC (Complete Blood Count), is a general test that provides information on red blood cells, white blood cells, and platelets but is not specific to monitoring coagulation therapy.
Choice C, PTT (Partial Thromboplastin Time), is another coagulation test but is not as commonly used for monitoring Coumadin therapy.
Choice D, WBC (White Blood Cell count), is unrelated to monitoring coagulation therapy and is used to assess immune system function.
Question 2 of 5
During the implementation phase of the nursing process when working with a hospitalized adult, which of the following actions would the nurse take?
Correct Answer: B
Rationale: During the implementation phase of the nursing process, the nurse is responsible for carrying out or delegating nursing interventions and documenting nursing activities and client responses in the medical records. Option A involves diagnosing, which is part of the nursing process's earlier phases. Option C pertains to planning, which precedes implementation. Option D relates to evaluation, which comes after the implementation phase.
Question 3 of 5
After instructing the client on crutch walking technique, the nurse should evaluate the client's understanding by using which of the following methods?
Correct Answer: A
Rationale: After teaching the client on crutch walking technique, assessing the client's understanding is crucial. The most effective method to evaluate the client's comprehension of a hands-on skill like crutch walking technique is through a return demonstration. This allows the nurse to observe the client performing the technique, ensuring they have grasped the instructions correctly and can execute the skill safely. While providing an explanation can help clarify doubts, it may not confirm the client's ability to perform the skill. Achieving a high score on a written test assesses cognitive understanding but not necessarily the practical application of the skill. Having the client explain the procedure to the family does not directly assess their ability to perform the skill themselves; it tests their ability to communicate the information to others.
Question 4 of 5
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?
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.
Question 5 of 5
What is the BEST blood collection location for a newborn?
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.
