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. A patient presents to the office with a pencil that has completely penetrated the palm of her hand. Which of the following treatments would be BEST in this situation?

• A. Assist the doctor while he sedates the patient and removes the pencil from her hand.
• B. Have the patient gently pull the pencil out of her hand and assist the physician with stitches.
• C. Wrap a gauze around the pencil, securing it as much as possible until the patient can get to a local emergency room.
• D. Tell the patient to go to the local emergency room. With a doctor's order, give the patient some aspirin for the pain.

Correct answer: C

Rationale: Penetrating wounds that leave an object behind may have damaged important blood vessels. Removing the object may lead to significant bleeding. The correct approach is to gently wrap the wound with the object in place to help control bleeding and prevent further injury. The patient should be taken promptly to the nearest emergency room where healthcare professionals can safely and appropriately remove the object and provide necessary treatment. Choice A is incorrect because removing the pencil without proper medical evaluation can worsen the injury. Choice B is incorrect because pulling out the object can cause additional damage and bleeding. Choice D is incorrect because giving aspirin without knowing the extent of the injury and causing potential drug interactions can be harmful.

3. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

4. The nurse is caring for a client in the late stages of Amyotrophic Lateral Sclerosis (A.L.S.). Which finding would the nurse expect?

• A. Confusion
• B. Loss of half of the visual field
• C. Shallow respirations
• D. Tonic-clonic seizures

Correct answer: C

Rationale: In the late stages of Amyotrophic Lateral Sclerosis (A.L.S.), respiratory muscles are affected, leading to shallow respirations. Confusion is not typically associated with A.L.S. Loss of half of the visual field suggests a neurological issue unrelated to A.L.S., while tonic-clonic seizures are not commonly seen in A.L.S. patients. Shallow respirations are a hallmark sign of respiratory muscle weakness in A.L.S. due to the degeneration of motor neurons.

5. What is the cause of meningitis that is fatal in half of the infected patients?

• A. Virus
• B. Bacteria
• C. Fungus
• D. Noninfectious agent

Correct answer: B

Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
