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 nurse is caring for a 2-year-old child after corrective surgery for Tetralogy of Fallot. The mother reports that the child has suddenly begun seizing. The nurse recognizes this problem is probably due to

• A. A cerebral vascular accident
• B. Postoperative meningitis
• C. Medication reaction
• D. Metabolic alkalosis

Correct answer: A

Rationale: The correct answer is a cerebral vascular accident. Polycythemia occurs as a physiological reaction to chronic hypoxemia, which commonly occurs in clients with Tetralogy of Fallot. Polycythemia and the resultant increased viscosity of the blood increase the risk of thromboembolic events, including cerebrovascular accidents. Signs and symptoms of a cerebral vascular accident include sudden paralysis, altered speech, extreme irritability or fatigue, and seizures. Postoperative meningitis (choice B) is less likely in this scenario as the sudden onset of seizing is more indicative of a vascular event rather than an infection. Medication reaction (choice C) is not the most probable cause given the history provided. Metabolic alkalosis (choice D) is not associated with sudden seizing in this context.

3. Which assessment finding is of most concern for a 46-year-old woman with acute pancreatitis?

• A. Absent bowel sounds
• B. Abdominal tenderness
• C. Left upper quadrant pain
• D. Palpable abdominal mass

Correct answer: D

Rationale: The correct answer is a palpable abdominal mass. In a 46-year-old woman with acute pancreatitis, a palpable abdominal mass may indicate the presence of a pancreatic abscess, which requires rapid surgical drainage to prevent sepsis. Absent bowel sounds, abdominal tenderness, and left upper quadrant pain are common symptoms in acute pancreatitis but do not necessarily indicate an immediate need for surgical intervention. Therefore, the presence of a palpable abdominal mass is the most concerning finding in this scenario.

4. The parents of an infant who underwent surgical repair of bladder exstrophy ask if the infant will be able to control their bladder as they get older. How should the nurse respond?

• A. Your child will need catheterization until bladder control is gained.
• B. Your child will be able to control their bladder like other children.
• C. You should potty train your child at the same time you normally would.
• D. Your child will not have a sphincter mechanism for the first 3 to 5 years, so urine will drain freely.

Correct answer: D

Rationale: Bladder exstrophy is a congenital defect where the infant is born with the bladder located on the outside of the body. Surgical repair typically occurs within the first 1 to 2 days of life. In the following 3 to 5 years post-surgery, urine will drain freely from the urethra due to the absence of a sphincter mechanism. This period allows the bladder to develop capacity as the child grows. Subsequent surgical interventions will be required to establish a functioning sphincter mechanism. Therefore, the correct response is that the child will not have a sphincter mechanism for the first 3 to 5 years, leading to urine draining freely. Options A, B, and C are incorrect as they do not align with the physiological process and management of bladder exstrophy.

5. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.
