Nursing Elites

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

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

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. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

3. A client who is receiving long-term steroid therapy complains of blurred vision. Which intervention should the nurse implement first?

• A. Instruct the client to use artificial tears to lubricate the eyes
• B. Administer an ophthalmic antibiotic as prescribed
• C. Arrange for the client to see an optometrist for an eye exam
• D. Notify the healthcare provider immediately

Correct answer: D

Rationale: The correct answer is to notify the healthcare provider immediately (Option D). Blurred vision in a client on long-term steroid therapy can be a sign of serious conditions like cataracts or glaucoma, which need urgent medical evaluation and management. Instructing the client to use artificial tears (Option A) may help with dry eyes but does not address the underlying cause of blurred vision. Administering an ophthalmic antibiotic (Option B) is not indicated unless there is a specific infection present. Referring the client to an optometrist for an eye exam (Option C) may delay necessary medical intervention by the healthcare provider, who should be involved promptly in this situation.

4. A male client is prescribed clozapine (Clozaril), an antipsychotic medication, for the management of schizophrenia. Which client history should the nurse report to the healthcare provider before administering the first dose of this medication?

• A. History of depression
• B. History of cardiac arrhythmia
• C. History of seizures
• D. History of diabetes mellitus

Correct answer: B

Rationale: The correct answer is B: History of cardiac arrhythmia. Clozapine can lead to severe cardiovascular problems, making it crucial to report any history of cardiac arrhythmia to the healthcare provider before administering the medication. Choices A, C, and D are less concerning in this context as they are not directly associated with potential serious complications related to clozapine use.

5. A gravida 2 para 1, at 38-weeks gestation, scheduled for a repeat cesarean section in one week, is brought to the labor and delivery unit complaining of contractions every 10 minutes. While assessing the client, the client's mother enters the labor suite and says in a loud voice, 'I've had 8 children and I know she's in labor. I want her to have her cesarean section right now!' What action should the nurse take?

• A. Tell the mother to stop speaking for the client.
• B. Notify the charge nurse of the situation.
• C. Request that the mother leave the room.
• D. Request security to remove her from the room.

Correct answer: C

Rationale: In this scenario, the most appropriate action for the nurse to take is to request that the mother leave the room. This is important to maintain a calm environment and allow the healthcare team to assess and manage the situation without interference. Option A is not the best choice as it may escalate the situation. Option B, notifying the charge nurse, could be considered after addressing the immediate need to remove the mother from the room. Option D, requesting security to remove her, is not necessary at this point and may further escalate the situation unnecessarily.
