Nursing Elites

1. A client with a history of myocardial infarction is experiencing chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Administer aspirin as prescribed.
• C. Administer nitroglycerin sublingually as prescribed.
• D. Obtain an electrocardiogram (ECG).

Correct answer: A

Rationale: Administering oxygen therapy is the initial priority in managing chest pain in a client with a history of myocardial infarction. Oxygen therapy helps improve oxygenation, which is crucial in reducing myocardial damage. While administering aspirin and nitroglycerin are essential interventions in the treatment of myocardial infarction, oxygen therapy takes precedence because it addresses the immediate need for oxygen supply to the heart muscle. Obtaining an ECG is important but can be done after ensuring adequate oxygenation.

2. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which assessment finding is most concerning?

• A. INR of 3.5
• B. Prothrombin time (PT) of 15 seconds
• C. Headache
• D. Blood pressure of 140/90 mmHg

Correct answer: C

Rationale: The correct answer is C. A headache in a client with a history of atrial fibrillation receiving warfarin (Coumadin) is concerning as it may indicate bleeding, which requires immediate assessment and intervention. Headaches can be a symptom of increased intracranial pressure due to bleeding, especially in patients on anticoagulants. Options A and B are within acceptable ranges for a client on warfarin therapy, indicating that the medication is effectively managing the clotting times. Option D, a blood pressure of 140/90 mmHg, while elevated, is not directly related to the client's condition of atrial fibrillation and warfarin therapy.

3. A client with a history of myocardial infarction is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of myocardial infarction and chest pain. This test provides immediate information about the heart's electrical activity. Choice B, Chest X-ray, is used to visualize the structures of the chest, including the heart and lungs, but it does not directly assess for cardiac ischemia. Choice C, Arterial blood gases (ABGs), measures the oxygen and carbon dioxide levels in the blood and assesses acid-base balance, which is not the primary concern in this scenario. Choice D, Echocardiogram, is an ultrasound of the heart that provides information about the heart's structure and function, but it is not the initial diagnostic test for assessing cardiac ischemia in this situation.

4. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer IV fluids as prescribed
• C. Check the client's blood glucose level
• D. Prepare the client for immediate dialysis

Correct answer: B

Rationale: Administering IV fluids as prescribed should be the first intervention for a client with diabetes mellitus admitted with a blood glucose level of 600 mg/dl and unresponsive. This intervention is crucial in managing hyperglycemia by helping to correct dehydration and electrolyte imbalances. Administering 50% dextrose IV push (Choice A) would worsen hyperglycemia in this scenario. Checking the client's blood glucose level (Choice C) is important but not the priority when dealing with an unresponsive client with severe hyperglycemia. Immediate dialysis preparation (Choice D) is not indicated as the first intervention for hyperglycemia.

5. A client with a history of chronic kidney disease (CKD) is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum creatinine
• B. Blood urea nitrogen (BUN)
• C. Serum potassium
• D. Serum glucose

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in patients with CKD because contrast agents can potentially worsen kidney function and lead to contrast-induced nephropathy. Monitoring serum creatinine helps assess kidney function and determine the risk of complications. Choices B, C, and D are less relevant in this scenario. Blood urea nitrogen (BUN) is another marker of kidney function, but serum creatinine is a more specific indicator. Serum potassium levels are important in assessing electrolyte balance but are not directly related to the risk of contrast-induced nephropathy. Serum glucose levels are not typically a primary concern before a CT scan with contrast in a patient with CKD.
