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. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.

3. A patient is found unconscious in their room with rhythmic jerking of all four extremities and heavy foaming at the mouth. The patient was on seizure precautions with bedrails up and padded. What is the priority action for the nurse to take?

• A. Administer Lorazepam (Ativan)
• B. Turn the patient to his/her side
• C. Call the physician
• D. Suction the patient

Correct answer: B

Rationale: The nurse's priority action should be to turn the patient to his/her side. This position helps maintain an open airway and prevents aspiration of secretions or vomitus. Administering Lorazepam (Ativan) without ensuring a clear airway could lead to further complications. Calling the physician is important, but immediate interventions to protect the airway take precedence. Suctioning the patient may be necessary but should not be the initial action; positioning for airway protection is the priority.

4. The nurse plans health care for a community with a large number of recent immigrants from Vietnam. Which intervention is the most important for the nurse to implement?

• A. Hepatitis testing
• B. Tuberculosis screening
• C. Contraceptive teaching
• D. Colonoscopy information

Correct answer: B

Rationale: Tuberculosis (TB) is prevalent in many parts of Asia, including Vietnam, and the incidence of TB is higher in immigrants from Vietnam compared to the general U.S. population. Conducting tuberculosis screening is crucial to identify and address any cases promptly, especially in a community with recent immigrants from Vietnam. While teaching about contraceptive use, providing colonoscopy information, and testing for hepatitis may be relevant for certain individuals in the community, they are not as universally important as tuberculosis screening due to the increased risk of TB among Vietnamese immigrants.

5. The patient who has two fractured ribs from an automobile accident is receiving discharge teaching. Which statement by the patient indicates effective teaching?

• A. I am going to buy a rib binder to wear during the day.
• B. I can take shallow breaths to prevent my chest from hurting.
• C. I should plan on taking the pain pills only at bedtime so I can sleep.
• D. I will use the incentive spirometer every hour or two during the day.

Correct answer: D

Rationale: The correct answer is, 'I will use the incentive spirometer every hour or two during the day.' After sustaining rib fractures, it is crucial to prevent complications like atelectasis and pneumonia by practicing deep breathing and coughing. Using the incentive spirometer helps in maintaining lung expansion and preventing respiratory issues. Buying a rib binder could restrict chest expansion and hinder deep breathing efforts, increasing the risk of atelectasis. Taking shallow breaths may not effectively expand the lungs, leading to potential respiratory complications. Relying solely on pain medication at bedtime may not adequately address the need for lung expansion and prevention of respiratory complications during the day.
