Nursing Elites

1. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

2. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

• A. Assist the client in using the bedside commode.
• B. Administer stool softeners daily as prescribed.
• C. Administer antidysrhythmics prn as ordered.
• D. Maintain the client on strict bed rest.

Correct answer: B

Rationale: Administering stool softeners daily is crucial to prevent straining during defecation, which can lead to the Valsalva maneuver. Straining can increase intrathoracic pressure, decrease venous return to the heart, and reduce cardiac output, potentially worsening the client's condition. If constipation occurs, the use of laxatives may be necessary to avoid straining. Administering antidysrhythmics on an as-needed basis is not indicated for preventing the Valsalva maneuver; they are used to manage dysrhythmias. Strict bed rest is not necessary and may lead to complications such as deconditioning, DVT, and respiratory issues in the absence of specific medical indications.

3. 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.

4. The nurse cares for a patient who has just had a thoracentesis. Which assessment information obtained by the nurse is a priority to communicate to the health care provider?

• A. Oxygen saturation is 88%.
• B. Blood pressure is 145/90 mm Hg.
• C. Respiratory rate is 22 breaths/minute when lying flat.
• D. Pain level is 5 (on a 0 to 10 scale) with a deep breath.

Correct answer: A

Rationale: The correct answer is 'Oxygen saturation is 88%.' Following a thoracentesis, oxygen saturation should improve. A saturation of 88% suggests a potential complication like pneumothorax. While the other assessment findings are important, the priority is to address the low oxygen saturation to prevent further complications. High blood pressure and respiratory rate may also need attention, but the immediate concern is the oxygen saturation level. Pain level, though significant for the patient's comfort, takes lower priority compared to the potential life-threatening issue of hypoxia.

5. Which of the following factors may alter the level of consciousness in a patient?

• A. Alcohol
• B. Electrolytes
• C. Infection
• D. All of the above may cause altered level of consciousness

Correct answer: D

Rationale: Various factors can lead to altered levels of consciousness in a patient. Alcohol consumption can depress the central nervous system and cause changes in consciousness. Electrolyte imbalances, such as hyponatremia or hypernatremia, can disrupt brain function and affect consciousness. Infections, especially those affecting the brain like encephalitis, can also lead to alterations in consciousness. Therefore, all of the choices provided - Alcohol, Electrolytes, and Infection - can potentially cause changes in the level of consciousness. Remember the acronym AEIOU-TIPPS to recall common causes of decreased level of consciousness, including Alcohol, Electrolytes, and Infection, among others.
