A nurse is collecting data from a child who has muscular dystrophy. Which of the following findings should the nurse expect? (Select all that Apply)
Spinal defect and sac-like protrusion
Muscular weakness in lower extremities
Kyphosis of the lower spine
Purposeless, involuntary, abnormal movements
Unsteady waddling gait
Correct Answer : B,C,E
Choice A rationale
Spinal defects and sac-like protrusions are not typically associated with muscular dystrophy. They are more commonly seen in conditions like spina bifida.
Choice B rationale
Muscular weakness in the lower extremities is a common symptom of muscular dystrophy. This is due to the progressive degeneration of muscle fibers, which leads to weakness and loss of muscle mass.
Choice C rationale
Kyphosis of the lower spine can be a complication of muscular dystrophy. As the muscles supporting the spine weaken, the spine can curve abnormally, leading to kyphosis.
Choice D rationale
Purposeless, involuntary, abnormal movements are not typically associated with muscular dystrophy. These symptoms are more commonly seen in neurological conditions like Huntington’s disease or certain types of cerebral palsy.
Choice E rationale
An unsteady waddling gait is often seen in individuals with muscular dystrophy. This is due to the progressive weakness and loss of muscle mass in the lower extremities.

Correct Answer is B
Explanation
Choice A rationale:
Abdominal rigidity and pain on palpation are not typical signs of pyloric stenosis. Pyloric stenosis usually presents with non-bilious projectile vomiting, a palpable olive-shaped mass in the upper abdomen, and signs of dehydration.
Choice B rationale:
A rounded abdomen and hypoactive bowel sounds are characteristic signs of pyloric stenosis. The hypertrophied pyloric muscle obstructs the passage of food from the stomach to the duodenum, leading to gastric distention, visible peristalsis, and vomiting. The infant may appear hungry after vomiting and will continue to feed, leading to weight loss.
Choice C rationale:
Visible peristalsis and weight loss are consistent with pyloric stenosis. The visible peristalsis occurs as the infant tries to force the stomach contents through the narrowed pyloric sphincter. Weight loss is a result of poor feeding and vomiting.
Choice D rationale:
Distention of the lower abdomen and constipation are not typical findings in pyloric stenosis. Constipation suggests a lower gastrointestinal issue, while pyloric stenosis primarily affects the upper gastrointestinal tract.
Correct Answer is ["3.125"]
Explanation
The child weighs 22 lb, which is approximately 10 kg (since 1 kg is approximately 2.2 lb).
The prescribed dose of acetaminophen is 10 mg/kg. Step 1 is: Calculate the total dose of acetaminophen for the child. This is done by multiplying the child’s weight in kg by the prescribed dose in mg/kg. 10 kg×10 mg/kg=100 mg The available acetaminophen liquid is 160 mg/5 mL. Step 2 is: Calculate the volume of acetaminophen liquid to administer. This is done by setting up a proportion with the total dose of acetaminophen and the concentration of the available liquid. x mL100 mg=5 mL160 mg Solving for x gives: x=160 mg mg×5 mL=3.125 mL Therefore, the nurse should administer approximately 3.125 mL of the acetaminophen liquid. .
