1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. When preparing to insert a nasogastric (NG) tube for a client admitted to the surgical unit with symptoms of a possible intestinal obstruction, which intervention should the nurse implement?

Correct answer: A

Rationale: Elevating the head of the bed to 60 to 90 degrees is essential when inserting an NG tube. This position helps facilitate the passage of the tube through the esophagus into the stomach and reduces the risk of aspiration. Administering an antiemetic may be necessary to control nausea or vomiting, but it is not the primary intervention when inserting an NG tube. Preparing the client for surgery is not indicated solely for the insertion of an NG tube. Providing oral care is important for maintaining oral hygiene but is not directly related to inserting an NG tube.

3. A male client with an antisocial personality disorder is admitted to an inpatient mental health unit for multiple substance dependencies. When providing a history, the client justifies to the nurse his use of illicit drugs. Based on this pattern of behavior, this client's history is most likely to include which finding?

Correct answer: A

Rationale: The correct answer is A: Multiple convictions for misdemeanors and class B felonies. Clients with antisocial personality disorder often engage in behaviors that disregard societal rules and norms, leading to legal issues and criminal activities. This behavior is characteristic of individuals with antisocial personality disorder. Choices B, C, and D are incorrect because individuals with this disorder are less likely to have stable employment, strong family relationships, or seek help when needed due to their pattern of defiance and disregard for authority and rules.

4. A client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). Which laboratory value should the nurse monitor closely?

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client with chronic kidney disease (CKD) is receiving epoetin alfa (Epogen), monitoring serum potassium levels closely is crucial. Epoetin alfa stimulates red blood cell production, which can lead to an increase in potassium levels. Hyperkalemia is a potential risk in these clients. Monitoring hemoglobin levels (choice A) is important in assessing the effectiveness of epoetin alfa therapy, but it is not the laboratory value that poses an immediate risk related to the medication. White blood cell count (choice B) and serum creatinine (choice D) are not directly affected by epoetin alfa therapy and are not the priority laboratory values to monitor in this case.

5. A client with a postoperative wound that eviscerated yesterday has an elevated temperature. What is the most important intervention for the nurse to implement?

Correct answer: B

Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.
