Nursing Elites

1. 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.

2. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?

• A. Elevate the lower extremities to 45 degrees to promote venous return
• B. Place Mr. C in the Trendelenburg position
• C. Administer total parenteral nutrition
• D. Monitor urine output

Correct answer: D

Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.

3. A 3-year-old had a hip spica cast applied 2 hours ago. In order to facilitate drying, the nurse should:

• A. Expose the cast to air and turn the child frequently.
• B. Use a heat lamp to reduce the drying time.
• C. Handle the cast with the abductor bar.
• D. Turn the child as little as possible.

Correct answer: A

Rationale: After a hip spica cast is applied, it is important to facilitate drying by exposing the cast to air and turning the child frequently, approximately every 2 hours. This helps ensure even drying and prevents skin breakdown. Using a heat lamp can cause burns and should be avoided. Handling the cast with the abductor bar is not necessary for the drying process and may cause discomfort to the child. Turning the child as little as possible is not recommended as regular turning helps prevent complications like pressure ulcers and stiffness.

4. A healthcare provider is assessing vital signs in pediatric patients. Which of the following vital signs is abnormal?

• A. 11-year-old male: 90 BPM, 22 RPM, 100/70 mmHg
• B. 13-year-old female: 105 BPM, 22 RPM, 105/50 mmHg
• C. 5-year-old male: 102 BPM, 24 RPM, 90/65 mmHg
• D. 6-year-old female: 100 BPM, 26 RPM, 90/70 mmHg

Correct answer: B

Rationale: The normal range of vital signs for pediatric patients varies with age. For 11 to 14-year-olds, the normal vital sign ranges are: Heart rate: 60-105 BPM; Respiratory rate: 12-20 RPM; Blood pressure: Systolic 85-120 mmHg, Diastolic 55-80 mmHg. The 13-year-old female in choice B has a diastolic blood pressure below the normal range, indicating hypotension. Additionally, her heart rate is at the upper limit of normal, and her respiratory rate is within normal limits. Choices A, C, and D all fall within the normal ranges for vital signs in pediatric patients.

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.
