The nurse is assessing the knowledge of new parents with a child born with maple syrup urine disease (MSUD). This is an autosomal recessive inherited disorder, which means that:

The disorder occurs in males and heterozygous females.

The disorder is carried on the X chromosome.

Both genes of a pair must be abnormal for the disorder to be expressed.

Only one copy of the abnormal gene is required for the disorder to be expressed.

Answer and Explanation

The Correct Answer is C

Both genes of a pair must be abnormal for the disorder to be expressed. In autosomal recessive inheritance, the gene for the disorder is located on an autosome (any chromosome other than a sex chromosome) and a person must inherit two copies of the abnormal gene (one from each parent) in order for the disorder to be expressed. If a person inherits only one copy of the abnormal gene, they are a carrier of the disorder but do not typically show symptoms.

Correct Answer is C

Explanation

This is because magnesium sulfate can cause respiratory depression, and a respiratory rate of 10 breaths/minute is significantly lower than the normal range of 12-20 breaths/minute. Other factors such as blood pressure of 138/88, the urinary output of 40 ml/hr, and patellar reflex of +2 should also be monitored, but they would not necessarily warrant immediate discontinuation of the magnesium sulfate infusion.

A. Meconium Aspiration Syndrome B. Respiratory Distress Syndrome C. Bronchopulmonary Dysplasia D. Transient tachypnea of the Newborn

Correct Answer is A

Explanation

The signs described are consistent with Meconium Aspiration Syndrome (MAS). Meconium aspiration occurs when the fetus has a bowel movement before or during delivery and inhales meconium-stained amniotic fluid into the lungs. This can lead to airway obstruction, chemical pneumonia, and respiratory distress, which may progress to respiratory failure, persistent pulmonary hypertension, and death. The presence of coarse breath sounds, acidosis, and the honeycomb appearance on X-ray are all signs of MAS.
