Nursing Elites

1. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?

• A. IgA
• B. IgD
• C. IgE
• D. IgG

Correct answer: D

Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.

2. The nurse is caring for a 73-year-old man with cirrhosis. Which data obtained by the nurse during the assessment will be of most concern?

• A. The patient complains of right upper-quadrant pain upon palpation.
• B. The patient's hands flap back and forth when the arms are extended.
• C. The patient has ascites and a 2-kg weight gain from the previous day.
• D. The patient's skin has multiple spider-shaped blood vessels on the abdomen.

Correct answer: B

Rationale: The most concerning data obtained by the nurse is the patient's hands flapping back and forth when the arms are extended, indicating asterixis, which is associated with hepatic encephalopathy. This condition can progress to hepatic coma and requires immediate attention. The presence of spider angiomas and right upper-quadrant abdominal pain are common findings in cirrhosis and do not warrant urgent intervention. Although ascites and weight gain suggest the need for treatment, they are not as alarming as the neurologic manifestations seen in hepatic encephalopathy.

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 patient scheduled for cataract surgery asks the nurse why they developed cataracts and how to prevent it in the future. What is the nurse's best response?

• A. Age is the biggest factor contributing to cataracts.
• B. Unprotected exposure to UV lights can cause cataracts.
• C. Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.
• D. Unfortunately, there is really nothing you can do to prevent cataracts, but they are amongst the most easily treated eye conditions.

Correct answer: C

Rationale: The correct answer is C: 'Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.' This response is the best choice as it covers the most common contributing factors for cataracts and includes preventable risk factors. Choice A is incorrect because while age is a significant factor in cataract development, it is not the only one. Choice B is incorrect as UV light exposure is a risk factor for cataracts but not the most comprehensive response. Choice D is incorrect as there are preventive measures individuals can take to reduce their risk of developing cataracts, such as protecting their eyes from UV light and managing other risk factors.

5. The nurse develops a plan of care to prevent aspiration in a high-risk patient. Which nursing action will be most effective?

• A. Turn and reposition immobile patients at least every 2 hours.
• B. Place patients with altered consciousness in side-lying positions.
• C. Monitor for respiratory symptoms in immunosuppressed patients.
• D. Insert nasogastric tube for feedings in patients with swallowing problems.

Correct answer: B

Rationale: To prevent aspiration in a high-risk patient, the most effective nursing action is to place patients with altered consciousness in side-lying positions. This position helps decrease the risk of aspiration as it prevents pooling of secretions and facilitates drainage. Turning and repositioning immobile patients every 2 hours is essential for preventing pressure ulcers and improving circulation but does not directly address the risk of aspiration. Monitoring respiratory symptoms in immunosuppressed patients is crucial to detect pneumonia early, but it does not directly prevent aspiration. Inserting a nasogastric tube for feedings in patients with swallowing problems may be necessary for nutritional support but does not address the risk of aspiration directly. Patients at high risk for aspiration include those with altered consciousness, difficulty swallowing, and those with nasogastric intubation, among others. Placing patients with altered consciousness in a side-lying position is a key intervention to reduce the risk of aspiration in this population. Other high-risk groups for aspiration include those who are seriously ill, have poor dentition, or are on acid-reducing medications.
