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. A couple asks the nurse about risks of several birth control methods. What is the most appropriate response by the nurse?

• A. Norplant is safe and can be easily removed.
• B. Oral contraceptives should not be used by smokers.
• C. Depo-Provera is convenient with few side effects.
• D. The IUD provides protection against pregnancy and infection.

Correct answer: B

Rationale: The correct answer is that oral contraceptives should not be used by smokers. The use of oral contraceptives in a woman who smokes increases the risk of cardiovascular problems, such as thromboembolic disorders. This is due to the combined effect of smoking and hormonal contraceptives. Choices A, C, and D are incorrect because they do not address the specific risk associated with smoking and oral contraceptives. Norplant's safety and ease of removal, Depo-Provera's convenience with few side effects, and the IUD's protection against pregnancy and infection are important points but not directly related to the increased risks for smokers using oral contraceptives.

3. A teen patient is admitted to the hospital by his physician who suspects a diagnosis of acute glomerulonephritis. Which of the following findings is consistent with this diagnosis? Select one that doesn't apply.

• A. Urine specific gravity of 1.040.
• B. Urine output of 350 ml in 24 hours.
• C. Brown ("tea-colored"?) urine.
• D. Generalized edema.

Correct answer: D

Rationale: The correct answer is 'Generalized edema.' Acute glomerulonephritis typically presents with periorbital edema, not generalized edema. Findings in acute glomerulonephritis include dark, smoky, or tea-colored urine (hematuria) due to red blood cells in the urine, elevated blood pressure, and proteinuria. The urine specific gravity may be high due to decreased urine output, but a urine output of 350 ml in 24 hours is extremely low and suggestive of renal impairment. Generalized edema is more commonly associated with nephrotic syndrome, where there is significant proteinuria leading to hypoalbuminemia and subsequent fluid retention in tissues. In acute glomerulonephritis, the edema is usually limited to the face and lower extremities, not generalized.

4. An infant has just returned to the nursing unit after surgical repair of a cleft lip on the right side. The nurse should place the infant in which best position at this time?

• A. Prone position
• B. On the stomach
• C. Left lateral position
• D. Right lateral position

Correct answer: C

Rationale: After surgical repair of a cleft lip on the right side, the nurse should position the infant carefully to ensure comfort and prevent complications. Placing the infant in the prone position or on the stomach is not recommended as it may cause rubbing of the surgical site against the mattress. The optimal position for the infant is the left lateral position, away from the surgical repair site, to minimize the risk of trauma. Placing the infant on the right lateral position would be contraindicated as it is on the side of the repair. Additionally, positioning the infant upright on the back can help prevent airway obstruction by secretions, blood, or the tongue. Therefore, the correct choice is to place the infant in the left lateral position to promote safety and comfort post cleft lip surgery.

5. Which clinical manifestations are recognized in nephrotic syndrome?

• A. Hematuria, bacteriuria, weight gain
• B. Gross hematuria, albuminuria, fever
• C. Hypertension, weight loss, proteinuria
• D. Massive proteinuria, hypoalbuminemia, edema

Correct answer: D

Rationale: Nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and edema. In this syndrome, there is loss of proteins, particularly albumin, in the urine leading to hypoalbuminemia, fluid retention, and subsequent edema. This results in elevated lipid levels like hypercholesterolemia, but not hypertension. Therefore, choices A, B, and C are incorrect. Hematuria, bacteriuria, fever, and weight loss are not typically associated with nephrotic syndrome, distinguishing it from other kidney disorders.
