Correct Answer: B,C,E

Rationale:
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: D

Rationale: Discouraging the client from ambulating is not the best action. While it's important to limit weight-bearing activities initially, movement is encouraged to promote circulation and prevent complications such as deep vein thrombosis. Using a hair dryer on a hot setting to dry the cast is not recommended. Heat can cause the cast to dry out and crack, and it can also burn the skin. Keeping the client's leg in a dependent position is not advisable. This can lead to increased swelling and pain, and potentially delay healing. Performing a neurovascular check of the lower extremities is the correct action. This involves assessing for pain, pallor, pulselessness, paresthesia, and paralysis. These checks are crucial for monitoring for complications such as compartment syndrome and ensuring the cast is not too tight.

Correct Answer: C

Rationale: Administering syrup of ipecac is not recommended in cases of iron overdose. Ipecac was once used to induce vomiting in cases of poisoning, but it is no longer recommended due to potential complications and lack of evidence for effectiveness. Giving the child orange juice will not help in this situation. While vitamin C can enhance iron absorption, it does not have an effect on iron that has already been absorbed into the body. Contacting the poison control center is the appropriate action. They can provide immediate advice on what to do in cases of potential iron overdose. Providing a high-carbohydrate snack will not help in this situation. It will not affect the absorption or toxicity of the iron.

Correct Answer: D

Rationale: Rapid respirations are not typically a manifestation of hypoglycemia. They are more commonly associated with conditions that cause metabolic acidosis, such as diabetic ketoacidosis. Diminished reflexes are not a typical manifestation of hypoglycemia. They may be seen in conditions affecting the nervous system. Acetone breath is not a manifestation of hypoglycemia. It is a sign of ketoacidosis, which is a complication of hyperglycemia, not hypoglycemia. Diaphoresis, or sweating, is a common symptom of hypoglycemia. The body produces sweat as part of the sympathetic nervous system's response to hypoglycemia.

Correct Answer: A

Rationale:
Step 1 is to convert the child's weight from pounds to kilograms. This is done by dividing the weight in pounds by 2.2, so 34 lbs ÷ 2.2 = 15.45 kg.
Step 2 is to calculate the dose in mg. This is done by multiplying the weight in kg by the dosage per kg, so 15.45 kg × 35 mg/kg = 540.75 mg.
Step 3 is to convert the dose in mg to ml. This is done by dividing the dose in mg by the concentration of the medication in mg/ml, so 540.75 mg ÷ 50 mg/ml = 10.815 ml. So, the total daily dosage in ml for this child is approximately 10.82 ml, rounded to the nearest hundredth as required.
