Nursing Elites

1. Alteplase recombinant, or tissue plasminogen activator (t-PA), a thrombolytic enzyme, is administered during the first 6 hours after onset of myocardial infarction (MI) to:

• A. Control chest pain.
• B. Reduce coronary artery vasospasm.
• C. Control the arrhythmias associated with MI.
• D. Revascularize the blocked coronary artery.

Correct answer: D

Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.

2. A client is scheduled for a barium swallow (esophagography) in 2 days. The nurse, providing preprocedure instructions, should tell the client to:

• A. Eat a regular supper and breakfast
• B. Remove all metal and jewelry before the test
• C. Expect diarrhea for a few days after the procedure
• D. Take all oral medications as scheduled with milk on the day of the test

Correct answer: B

Rationale: The correct answer is B: 'Remove all metal and jewelry before the test.' Before a barium swallow procedure, the client should fast for 8 to 12 hours to ensure the stomach and intestines are empty for optimal visualization. Removing all metal and jewelry is essential to prevent any interference with x-ray imaging. Choice A is incorrect because the client should fast, not eat supper and breakfast, before the test. Choice C is incorrect as diarrhea is not an expected outcome of a barium swallow. Choice D is incorrect as the client should not take any oral medications with milk on the day of the test to ensure accurate test results.

3. The charge nurse of the medical-surgical unit is making staff assignments. Which staff member should be assigned to a client with chronic kidney disease who is exhibiting a low-grade fever and a pericardial friction rub?

• A. Registered nurse who just floated from the surgical unit
• B. Registered nurse who just floated from the dialysis unit
• C. Registered nurse who was assigned the same client yesterday
• D. Licensed practical nurse with 5 years of experience on this floor

Correct answer: C

Rationale: The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is crucial to assess subtle changes in clients' conditions. Therefore, the registered nurse (RN) who previously cared for this client should be assigned again. Float nurses may lack knowledge of the unit and its clients, potentially leading to oversight of critical details. The licensed practical nurse, while experienced, may not possess the advanced assessment skills and education level of an RN to effectively evaluate and manage pericarditis in this client.

4. A client is being prepared for a colonoscopy. Into which position does the nurse assist the client for the procedure?

• A. Left Sims' position
• B. Lithotomy position
• C. Knee-chest position
• D. Right Sims' position

Correct answer: A

Rationale: During a colonoscopy, the client is positioned in the left Sims' position. This position is chosen as it optimally utilizes the client’s anatomy to facilitate the introduction of the colonoscope. The lithotomy position (Choice B) is commonly used for gynecological exams, not colonoscopies. The knee-chest position (Choice C) is typically employed for rectal examinations or certain surgical procedures, not colonoscopies. The right Sims' position (Choice D) is a less common position for colonoscopy compared to the left Sims' position.

5. A healthcare professional is monitoring the respiratory status of a client who has just undergone surgery and is wearing a pulse oximeter. Which of the following coexisting problems is cause for the healthcare professional to suspect that the oxygen saturation readings are not entirely accurate?

• A. Infection
• B. Hypertension
• C. Low blood pressure
• D. Loss of cough reflex

Correct answer: C

Rationale: Low blood pressure (hypotension), shock, and the use of peripheral vasoconstricting medications can lead to inaccurate pulse oximetry readings due to impaired peripheral perfusion. Hypertension and infection are not typically associated with inaccurate pulse oximetry readings, while the loss of cough reflex does not directly affect oxygen saturation readings.
