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 clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Foul-smelling, ribbon-like stools

Correct answer: D

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.

3. Mr. L was working in his garage at home and had an accident with a power saw. He is brought into the emergency department by a neighbor with a traumatic hand amputation. What is the first action of the nurse?

• A. Place a tourniquet at the level of the elbow
• B. Apply direct pressure to the injury
• C. Administer a bolus of 0.9% Normal Saline
• D. Elevate the injured extremity on a pillow

Correct answer: B

Rationale: The correct first action for the nurse in this scenario is to apply direct pressure to the injury. When a client presents with traumatic hand amputation causing excessive bleeding, the immediate goal is to control the bleeding. Applying direct pressure with a sterile dressing helps to stem the flow of blood and stabilize the patient. Placing a tourniquet at the level of the elbow should be avoided initially as it may lead to further complications such as tissue damage. Administering a bolus of 0.9% Normal Saline is not the priority in this situation where hemorrhage control is crucial. Elevating the injured extremity on a pillow does not address the primary concern of controlling the bleeding and stabilizing the patient.

4. The nurse is preparing to care for a child with a diagnosis of intussusception. The nurse reviews the child's record and expects to note which sign of this disorder documented?

• A. Watery diarrhea
• B. Ribbon-like stools
• C. Profuse projectile vomiting
• D. Bright red blood and mucus in the stools

Correct answer: D

Rationale: Intussusception is a condition where a part of the bowel slides into the next section, causing an obstruction. The classic presentation includes severe abdominal pain that is crampy, intermittent, and may cause the child to draw knees to the chest. While vomiting can occur, it is not typically projectile in nature. A key hallmark of intussusception is the passage of bright red blood and mucus in the stools, often described as currant jelly-like. Watery diarrhea and ribbon-like stools are not typical signs of intussusception and should not be expected in a child with this condition.

5. 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.
