Nursing Elites

1. A nurse is caring for a patient admitted to the emergency room for an ischemic stroke with marked functional deficits. The physician is considering the use of fibrinolytic therapy with TPA (tissue plasminogen activator). Which history-gathering question would not be important for the nurse to ask?

• A. What time did you first notice symptoms consistently appearing?
• B. Have you been taking any blood thinners such as heparin, lovenox, or warfarin?
• C. Have you had another stroke or head trauma in the previous 3 months?
• D. Have you had any blood transfusions within the previous year?

Correct answer: D

Rationale: The correct answer is 'Have you had any blood transfusions within the previous year?' This question is not relevant in the context of considering fibrinolytic therapy with TPA for an ischemic stroke. Blood transfusions within the previous year do not directly impact the decision to use TPA in the treatment of an acute ischemic stroke. The focus should be on factors such as the time of symptom onset, current medications like blood thinners, and recent history of strokes or head trauma, as these are more directly related to the decision-making process for administering TPA in this emergency situation.

2. A patient is scheduled for a magnetic resonance imaging (MRI) scan for suspected lung cancer. Which of the following is a contraindication to the study for this patient?

• A. The patient is allergic to shellfish.
• B. The patient has a pacemaker.
• C. The patient suffers from claustrophobia.
• D. The patient takes antipsychotic medication.

Correct answer: B

Rationale: The correct answer is that the patient has a pacemaker. A pacemaker is a contraindication to MRI scanning due to the interference with the magnetic fields of the MRI scanner. This interference can potentially deactivate the pacemaker, putting the patient at risk. Patients with cardiac implantable electronic devices (CIED) are at risk for inappropriate device therapy, device heating/movement, and arrhythmia during MRI. This necessitates special precautions such as scheduling in a CIED blocked slot or having electrophysiology nurse or technician support. It is important to ensure that the patient's pacemaker is MRI conditional before proceeding with the scan. The other choices, such as being allergic to shellfish, suffering from claustrophobia, or taking antipsychotic medication, are not direct contraindications to undergoing an MRI scan for suspected lung cancer.

3. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

4. Which assessment finding is of most concern for a 46-year-old woman with acute pancreatitis?

• A. Absent bowel sounds
• B. Abdominal tenderness
• C. Left upper quadrant pain
• D. Palpable abdominal mass

Correct answer: D

Rationale: The correct answer is a palpable abdominal mass. In a 46-year-old woman with acute pancreatitis, a palpable abdominal mass may indicate the presence of a pancreatic abscess, which requires rapid surgical drainage to prevent sepsis. Absent bowel sounds, abdominal tenderness, and left upper quadrant pain are common symptoms in acute pancreatitis but do not necessarily indicate an immediate need for surgical intervention. Therefore, the presence of a palpable abdominal mass is the most concerning finding in this scenario.

5. A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?

• A. Blood pressure (BP) is less than 140/90 mm Hg.
• B. Patient reports decreased exertional dyspnea
• C. Heart rate is between 60 and 100 beats/minute
• D. Patient's chest x-ray indicates clear lung fields

Correct answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.
