Nursing Elites

1. In which order should the nurse take the following actions for an older patient with new onset confusion who is normally alert and oriented?

• A. Obtain the oxygen saturation, Check the patient's pulse rate, Notify the health care provider, Document the change in status
• B. Obtain the oxygen saturation, Check the patient's pulse rate, Document the change in status, Notify the health care provider
• C. Document the change in status, Notify the health care provider, Check the patient's pulse rate, Obtain the oxygen saturation
• D. Document the change in status, Check the patient's pulse rate, Obtain the oxygen saturation, Notify the health care provider

Correct answer: B

Rationale: The correct order of actions for the nurse in this scenario is to first obtain the oxygen saturation to assess the patient's airway and oxygenation status. Next, checking the patient's pulse rate helps in evaluating circulation. Subsequently, documenting the change in the patient's status is important for maintaining an accurate record of care. Finally, notifying the health care provider is crucial to ensure timely intervention and further management. Choices A, C, and D are incorrect because assessing oxygen saturation should precede checking the pulse rate to address potential physiological causes of confusion. Additionally, documentation should follow patient assessment and notification of the healthcare provider for appropriate record-keeping and communication.

2. A 28-year-old male has been found wandering around in a confusing pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?

• A. Blood sugar check
• B. CT scan
• C. Blood cultures
• D. Arterial blood gases

Correct answer: A

Rationale: In a 28-year-old male presenting with confusion, sweating, and pallor, the most likely cause is hypoglycemia, especially with no mention of trauma or infection. Therefore, the initial test to be performed should be a blood sugar check to rule out low blood sugar levels. Checking blood sugar levels is crucial in such a scenario as hypoglycemia can lead to altered mental status. A CT scan (choice B) is not typically the initial test for altered mental status without any focal neurological signs or head trauma. Blood cultures (choice C) are more relevant in cases suspected of infection, which is not a primary concern in this scenario. Arterial blood gases (choice D) may be considered later if there are concerns about respiratory status or acid-base disturbances, but in this case, checking the blood sugar level is the most immediate and appropriate action.

3. After an unimmunized individual is exposed to hepatitis B through a needle-stick injury, which actions will the nurse plan to take (select one that does not apply)?

• A. Administer hepatitis B vaccine.
• B. Test for antibodies to hepatitis B.
• C. Teach about alpha-interferon therapy.
• D. Give hepatitis B immune globulin.

Correct answer: C

Rationale: In the case of exposure to hepatitis B, the nurse should plan to administer hepatitis B vaccine to provide active immunity. Testing for antibodies to hepatitis B is essential to determine the individual's immune status. Giving hepatitis B immune globulin is necessary for passive immunity in cases of exposure. However, teaching about alpha-interferon therapy is not part of the standard management for hepatitis B exposure. Interferon therapy and oral antivirals are typically used in the treatment of chronic hepatitis B infections, not for prophylaxis after exposure.

4. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

5. A client is scheduled for a percutaneous transluminal coronary angioplasty (PTCA). The nurse knows that a PTCA is:

• A. Surgical repair of a diseased coronary artery
• B. Placement of an automatic internal cardiac defibrillator
• C. Procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow
• D. Non-invasive radiographic examination of the heart

Correct answer: C

Rationale: Percutaneous transluminal coronary angioplasty (PTCA) is a procedure that compresses plaque against the wall of the diseased coronary artery to improve blood flow. It is performed during a cardiac catheterization to improve coronary artery blood flow in a diseased artery. Surgical repair of a diseased coronary artery is typically done through procedures like aorto-coronary bypass graft (ACBG) rather than PTCA. Placement of an automatic internal cardiac defibrillator (AICD) is a different procedure used for managing cardiac arrhythmias. Non-invasive radiographic examination of the heart refers to procedures like echocardiography or cardiac MRI, not PTCA.
