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. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Decreased deep tendon reflexes
• D. Muscle weakness

Correct answer: A

Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.

3. The nurse notes that a client who has undergone a thoracotomy has an increase in a large amount of dark red blood in the chest tube collection chamber. What action should the nurse take?

• A. Document the findings for this procedure as expected
• B. Notify the healthcare provider immediately
• C. Check the tube for kinks or dependent loops
• D. Increase the suction to the chest drainage system

Correct answer: B

Rationale: An increase in a large amount of dark red blood in the chest tube collection chamber may indicate active bleeding. The nurse should notify the healthcare provider immediately to address the situation promptly and prevent further complications. Documenting the findings without taking immediate action could delay necessary interventions. Checking the tube for kinks or dependent loops is a good practice but not the priority when dealing with a potentially life-threatening situation like active bleeding. Increasing the suction without healthcare provider's orders can lead to complications and is not appropriate in this scenario.

4. A client with cirrhosis is admitted with hepatic encephalopathy. Which clinical finding is most concerning?

• A. Confusion and altered mental status
• B. Increased abdominal girth
• C. Yellowing of the skin
• D. Peripheral edema

Correct answer: A

Rationale: Confusion and altered mental status are the most concerning clinical findings in a client with hepatic encephalopathy. These symptoms indicate worsening liver function and potential neurological complications, requiring immediate medical attention. Increased abdominal girth may suggest ascites, yellowing of the skin can indicate jaundice, and peripheral edema may be related to fluid retention, but in the context of hepatic encephalopathy, confusion and altered mental status take precedence due to the risk of rapid deterioration and the need for prompt management.

5. A 26-year-old female client is admitted to the hospital for treatment of a simple goiter, and levothyroxine sodium (Synthroid) is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?

• A. Palpitations and shortness of breath
• B. Bradycardia and constipation
• C. Lethargy and lack of appetite
• D. Muscle cramping and dry, flushed skin

Correct answer: A

Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication. Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.
