NCLEX PN Practice Questions Questions
Extract:
Question 1 of 5
A 54-year-old male is admitted to the cardiac unit with chest pain radiating to the jaw and left arm. Which enzyme would be most specific in the diagnosis of a myocardial infarction?
Correct Answer: D
Rationale: CK-MB (creatine phosphokinase muscle bond isoenzyme) is the most specific for a myocardial infarction. Troponin is also extremely reliable. Answers A, B, and C are nonspecific to myocardial infarctions, so they are incorrect.
Question 2 of 5
A client with an implantable cardioverter defibrillator (ICD) develops ventricular tachycardia (VT) with a pulse while admitted to the medical-surgical unit. The ICD fires multiple times without successfully stopping the VT, causing the client to become confused and difficult to rouse. Which action by the nurse is appropriate?
Correct Answer: D
Rationale: Persistent VT causing altered mental status requires synchronized cardioversion to restore normal rhythm.
Question 3 of 5
The best choice for the child following a tonsillectomy is:
Correct Answer: C
Rationale: A banana Popsicle is soothing, cold, and non-irritating to the surgical site. Liquids like punch or soda may sting, and ice cream is dairy, which can increase mucus.
Question 4 of 5
The nurse is talking with a client whose spouse recently attempted suicide. The client states, 'If I had not intervened, my spouse would have died. I cannot believe this is happening.' Which of the following responses would be most appropriate for the nurse to make?
Correct Answer: B
Rationale: Acknowledging the client's feelings and encouraging expression provides emotional support.
Question 5 of 5
An adult woman has been diagnosed with varicose veins. Which aspect of her history is most likely related to her diagnosis?
Correct Answer: A
Rationale: Multiple pregnancies increase intra-abdominal pressure and venous stasis, contributing to varicose veins. Running, normal weight, and sedentary work are less directly related.
