NCLEX RN Predictor Exam - Nurselytic

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.

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.

Correct Answer: B

Rationale: The correct desired outcome for a nursing diagnosis of 'Risk for impaired skin integrity' is to ensure that the skin remains intact and without redness during the hospital stay. This outcome directly addresses the risk identified in the diagnosis. Option A focuses on addressing immobility, which is not the priority for this diagnosis. Option C deals with pain relief, which is a separate concern. Option D is an intervention involving pressure prevention through repositioning, rather than an outcome related to skin integrity.

Correct Answer: C

Rationale: A patient with blood type AB has AB antigens on their red blood cells. This means they can only receive blood products that are compatible with these antigens.
Choice A is incorrect because an AB patient cannot receive plasma from a type B donor due to the antibodies present in type B plasma.
Choice B is incorrect because an AB patient cannot receive whole blood from a type A donor as it contains incompatible antigens.
Choice C is the correct answer because an AB patient can receive packed RBCs from a type O donor. Type O donors have no A or B antigens, making their blood compatible for transfusion to recipients with any blood type.
Therefore, choices A and B are incorrect, and the correct choice is C.
