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. Which interventions should the nurse include when creating a care plan for a child with hepatitis? Select one that doesn't apply.

• A. Providing a low-fat, well-balanced diet.
• B. Teaching the child effective hand-washing techniques.
• C. Notifying the primary health care provider (PHCP) if jaundice is present.
• D. Instructing the parents to avoid administering medications unless prescribed.

Correct answer: D

Rationale: The correct answer is instructing the parents to avoid administering medications unless prescribed. This choice is not directly related to the care of a child with hepatitis. It is essential for the nurse to educate the child and family about providing a low-fat, well-balanced diet to support the liver, teaching effective hand-washing techniques to prevent the spread of infection, and notifying the primary health care provider if jaundice is present to monitor the progression of the disease and adjust the treatment plan accordingly. Avoiding unnecessary medications is crucial, but it should be done under healthcare provider guidance, so the statement should be revised to reflect this aspect. Therefore, the other options are appropriate for the care of a child with hepatitis.

3. Which of these individuals would the nurse suspect as having the greatest risk of contracting Hepatitis B?

• A. A sexually active 45-year-old man who has Type 1 Diabetes
• B. A 75-year-old woman who lives in a crowded nursing home
• C. A child who lives in a country with poor sanitation and hygiene standards
• D. A sexually active 23-year-old man who works in a hospital

Correct answer: D

Rationale: The correct answer is a sexually active 23-year-old man who works in a hospital. This individual is at the highest risk of contracting Hepatitis B due to exposure in a healthcare setting where potential bloodborne pathogens are present. Being sexually active also increases the risk of transmission through sexual contact. Choice A, a 45-year-old man with Type 1 Diabetes, is not directly associated with an increased risk of Hepatitis B. Choice B, a 75-year-old woman living in a crowded nursing home, is at risk for other infections due to the living environment but not specifically for Hepatitis B. Choice C, a child in a country with poor sanitation, is more at risk for water or foodborne illnesses rather than Hepatitis B transmission.

4. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

5. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?

• A. It is an acute bowel obstruction.
• B. It is a condition that causes an acute inflammatory process in the bowel.
• C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
• D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.

Correct answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
