NCLEX RN Predictor Exam

1. For a patient who is blood type AB, which blood product can they receive?

A. Plasma from a type B donor
B. Whole blood from a type A donor
C. Packed RBCs from a type O donor
D. All of the above

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.

2. A patient who is displaying the defense mechanism of Compensation would:

A. Refuse to hear unwanted information.
B. Transfer feelings of negativity to someone else.
C. Overemphasize behaviors which accommodate for perceived weaknesses.
D. Place blame on others for personal actions or mistakes.

Correct answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings. Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

3. Which of the following is recommended by Joint Commission guidelines regarding the use of restraints?

A. Vest restraints should be used because they are the least restrictive type.
B. Restraints should be used for 48 hours in non-psychiatric patients.
C. Restraints should be applied to prevent wandering behavior.
D. Alternative measures must be attempted first.

Correct answer: D

Rationale: When considering the use of restraints, Joint Commission guidelines emphasize the importance of attempting alternative measures before resorting to restraint application. This ensures that a comprehensive assessment is conducted and less restrictive interventions are explored. Using restraints solely based on their perceived level of restrictiveness, as stated in choice A, is not in line with the recommended approach. Restraints should not be used to manage wandering behavior, as indicated in choice C. Additionally, the statement in choice B regarding the duration of restraint use is inaccurate, as restraints on non-psychiatric patients should not exceed 24 hours according to The Joint Commission.

4. Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?

A. Angina at rest
B. Thrombus formation
C. Dizziness
D. Falling blood pressure

Correct answer: B

Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.

5. A client is being seen for disrupted sleep patterns. The nurse encourages the client to verbalize feelings about sleep and inability to maintain adequate sleep habits. What is the rationale for this action?

A. The client most likely has a mental illness that should be treated before addressing sleep issues
B. The client may have unrecognized anxiety or fear that could be contributing to poor sleep habits
C. The client may become tired once they start talking
D. None of the above

Correct answer: B

Rationale: Clients experiencing disrupted sleep patterns may have underlying anxiety or fear contributing to their poor sleep habits. Encouraging clients to verbalize their feelings about sleep allows them to address any negative emotions that may be impacting their ability to sleep well. By working through these issues, clients may experience increased peace and relaxation, which can help promote better sleep. Option A is incorrect because assuming a mental illness without evidence can lead to mismanagement of the client's care. Option C is incorrect as it does not address the underlying emotional factors affecting the client's sleep patterns. Option D is incorrect as there is a specific rationale for encouraging the client to verbalize their feelings about sleep.
