Nursing Elites

1. In which chromosome pattern is Duchenne disease inherited?

• A. Autosomal dominant
• B. Autosomal recessive
• C. X-linked recessive
• D. Mitochondrial

Correct answer: C

Rationale: Duchenne disease is caused by a mutation in the DMD gene located on the X chromosome, leading to an X-linked recessive inheritance pattern. Males are typically affected by this disorder as they have only one X chromosome, while females are carriers with one normal and one affected X chromosome.

2. During a prenatal visit, the nurse discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

3. A young girl with a fractured radius has a cast applied. As the cast is drying, it is elevated above the level of her heart. Which assessment finding should the healthcare provider be reported to immediately?

• A. Itching sensation under the cast.
• B. Swelling of fingers with brisk capillary refill.
• C. Numbness and inability to move fingers.
• D. Visible bruising above the cast.

Correct answer: C

Rationale: Numbness and inability to move fingers are concerning findings that suggest potential nerve damage or compartment syndrome due to increased pressure within the cast. This requires immediate notification of the healthcare provider to prevent further complications or permanent damage.

4. A child who received multiple blood transfusions after correction of a congenital heart defect is demonstrating muscular irritability and oozing blood from the surgical incision. Which serum value is most important for the nurse to obtain before reporting to the healthcare provider?

• A. CO2 combining power
• B. Calcium
• C. Sodium
• D. Chloride

Correct answer: B

Rationale: The correct answer is Calcium. In this scenario, the child is displaying symptoms of muscular irritability and oozing blood, which are indicative of hypocalcemia. Calcium levels are crucial to monitor after multiple blood transfusions to prevent complications such as hypocalcemia, which can lead to these symptoms. Therefore, obtaining a serum calcium value is essential for the nurse to assess and address the child's condition effectively. CO2 combining power, Sodium, and Chloride levels are not directly associated with the symptoms described and are not the priority in this situation.

5. Using Nägele's rule, what is the estimated date of delivery for a pregnant client who reports that the first day of her last menstrual period was August 2, 2006?

• A. April 25, 2007.
• B. May 9, 2007.
• C. May 29, 2007.
• D. June 2, 2007.

Correct answer: B

Rationale: Nägele's rule is used to estimate the date of delivery. It involves adding 7 days to the first day of the last menstrual period (August 2), which gives August 9. Then, subtracting 3 months from August 9, we arrive at May 9 of the following year as the estimated date of delivery. This makes choice B, 'May 9, 2007,' the correct answer. Choices A, C, and D are incorrect as they do not follow the correct calculation based on Nägele's rule.
