Nursing Elites

1. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

3. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:

• A. Has increased airway obstruction.
• B. Has improved airway obstruction.
• C. Needs to be suctioned.
• D. Exhibits hyperventilation.

Correct answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

4. What action will the nurse plan to take for a 40-year-old patient with multiple sclerosis (MS) who has urinary retention caused by a flaccid bladder?

• A. Decrease the patient's evening fluid intake.
• B. Teach the patient how to use the Cred method.
• C. Suggest the use of adult incontinence briefs for nighttime only.
• D. Assist the patient to the commode every 2 hours during the day.

Correct answer: B

Rationale: For a 40-year-old patient with multiple sclerosis experiencing urinary retention due to a flaccid bladder, teaching the Cred method is the appropriate action. The Cred method involves applying manual pressure over the bladder to aid in bladder emptying. Decreasing fluid intake is not the correct approach as it will not address the underlying issue of bladder emptying and may lead to dehydration and urinary tract infections. Using adult incontinence briefs only addresses the symptom of incontinence without addressing the bladder emptying problem. Assisting the patient to the commode every 2 hours does not actively address the issue of improving bladder emptying as effectively as teaching the Cred method.

5. During a physical exam, a healthcare professional assisting a client suspected of having meningitis bends the client's leg at the hip to a 90-degree angle. When attempting to extend the leg at the knee, the client experiences severe pain. What type of test is being performed?

• A. Brudzinski's sign
• B. Romberg's sign
• C. Kernig's sign
• D. Babinski's sign

Correct answer: C

Rationale: The healthcare professional is performing Kernig's sign, a test for meningeal irritation often seen in meningitis cases. Kernig's sign involves bending the client's leg at a 90-degree angle at the hip and then attempting to extend the leg at the knee. Severe pain during this maneuver indicates a positive Kernig's sign, suggesting irritation of the meningeal membranes. Brudzinski's sign involves flexing the neck causing involuntary flexion of the hips and knees; Romberg's sign assesses balance and proprioception; Babinski's sign checks for abnormal reflexes in the foot.
