Nursing Elites

1. To prepare a 56-year-old male patient with ascites for paracentesis, the nurse should?

• A. place the patient on NPO status.
• B. assist the patient to lie flat in bed.
• C. ask the patient to empty the bladder.
• D. position the patient on the right side.

Correct answer: C

Rationale: To prepare a patient with ascites for paracentesis, the nurse should ask the patient to empty the bladder. This is important to decrease the risk of bladder perforation during the procedure. The patient should be positioned in Fowler's position to facilitate the procedure, not lie flat in bed, which can compromise breathing. Placing the patient on NPO status is unnecessary as sedation is not typically required for paracentesis. Positioning the patient on the right side is not a standard preparatory measure for paracentesis.

2. A client is being instructed in the use of an incentive spirometer. Which of the following statements from the nurse indicates correct teaching about using this device?

• A. Lie back in a reclining position while using the spirometer.
• B. Take slow deep breaths to reach your goal.
• C. Set a goal of using the spirometer at least 3 times per day.
• D. Practice coughing after taking 10 breaths.

Correct answer: D

Rationale: An incentive spirometer is a device used to improve lung function and reduce the risk of atelectasis. The correct way to use the spirometer is by sitting up and taking slow, deep breaths to achieve the set goal, not by lying back in a reclining position or taking rapid, quick breaths. Setting a goal of using the spirometer multiple times a day is beneficial, but it is not the best indicator of correct teaching. After using the spirometer, the client should practice coughing to help clear any loosened secretions that may have occurred during the breathing exercises.

3. 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.

4. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

5. A client is admitted for a head injury. His body is lying in an abnormal position and the physician states he is exhibiting decorticate posturing. Based on this assessment, the nurse can expect to find the client with:

• A. The legs extended and rotated internally; the elbow, wrists, and fingers flexed
• B. The legs pulled toward the chest; the head bent back at a 30-degree angle
• C. The back arched; the arms and legs extended and rigid
• D. The legs extended and rotated externally; the head turned to the right or the left

Correct answer: A

Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.
