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 has been assigned to care for a neonate just delivered who has gastroschisis. Which concern should the nurse address in the client's plan of care?

• A. Infection.
• B. Poor body image.
• C. Decreased urinary elimination.
• D. Cracking oral mucous membranes.

Correct answer: A

Rationale: In a neonate with gastroschisis, the bowel herniates through a defect in the abdominal wall without a covering membrane, which puts the neonate at high risk of infection. Immediate surgical repair is necessary due to the vulnerability of the exposed bowel to infection. Therefore, the most critical concern for the nurse to address in the plan of care of a neonate with gastroschisis is preventing infection. Poor body image is not a priority in neonatal care as neonates do not have body image concerns. Decreased urinary elimination is not typically a direct consequence of gastroschisis as it primarily affects the gastrointestinal system, not the genitourinary system. Cracking oral mucous membranes are not relevant to gastroschisis as it involves the lower gastrointestinal system, not the oral cavity.

3. When administering a-interferon and ribavirin (Rebetol) to a patient with chronic hepatitis C, the nurse should monitor for which complication?

• A. Leukopenia.
• B. Hypokalemia.
• C. Polycythemia.
• D. Hypoglycemia.

Correct answer: B

Rationale: When administering a-interferon and ribavirin (Rebetol) for chronic hepatitis C, the nurse should monitor for hypokalemia. This combination therapy is known to cause leukopenia, not polycythemia or hypoglycemia. Hypokalemia is a common electrolyte imbalance that can occur with these medications, making it the correct answer to monitor for in this case.

4. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

5. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
