Two hours after arriving on the medical-surgical unit, the client develops dyspnea. SaO2 is 91%, and the client is exhibiting audible wheezing and use of accessory muscles. Which of the following medications should the nurse expect to administer?

Correct Answer: D

Rationale: In this situation, the client is experiencing dyspnea, audible wheezing, and decreased oxygen saturation, indicating the presence of respiratory distress, likely due to bronchoconstriction. These are classic symptoms of an acute asthma exacerbation or an obstructive respiratory condition. Beta2 agonists, such as albuterol, are bronchodilators that work by relaxing the muscles in the airways, relieving bronchoconstriction and improving airflow. Administering a beta2 agonist promptly is crucial to provide relief and improve the client's respiratory status. Antibiotics, antivirals, and beta-blockers are not appropriate treatments for acute bronchoconstriction or asthma exacerbation.

Correct Answer: C

Rationale: Rickets is a self-limiting disease that affects the growth plates in bones, including the femoral head. It is primarily caused by a deficiency in vitamin D, which is necessary for proper bone mineralization and growth. Rickets is more common in children and can lead to weakened bones, deformities, and growth disturbances. With proper treatment and supplementation, rickets can be reversed and often resolves once the underlying vitamin D deficiency is addressed.

Correct Answer: B

Rationale: The baby's symptoms of shakiness, confusion, irritability, and slurred speech are indicative of hypoglycemia, which is low blood sugar. In a baby with newly diagnosed diabetes, the administration of insulin or oral hypoglycemic agents may have led to excessive lowering of blood glucose levels, causing these symptoms to manifest. It is crucial to address hypoglycemia promptly by administering a rapid-acting carbohydrate source such as glucose gel or juice to raise blood sugar levels back to normal range. Left untreated, severe hypoglycemia can lead to seizures, loss of consciousness, and potential long-term neurological damage. It is important for healthcare providers and caregivers to be vigilant in monitoring blood glucose levels in babies newly diagnosed with diabetes to prevent episodes of hypoglycemia.

Correct Answer: D

Rationale: Trendelenburg's sign is not a typical sign of congenital hip dysplasia. Trendelenburg's sign indicates weakness of the hip abductor muscles and is seen when a person stands on one leg and the pelvis on the unsupported side drops. The other options are more commonly associated with congenital hip dysplasia:

Correct Answer: C

Rationale: Nephrosis in children is also known as nephrotic syndrome, which is characterized by the presence of albuminuria (loss of protein in the urine), hypoproteinemia (low levels of protein in the blood), and edema (swelling due to fluid retention). This condition results from damage to the filters in the kidneys, leading to increased permeability and loss of protein in the urine. The classic triad of symptoms in nephrotic syndrome includes proteinuria, hypoalbuminemia, and edema. Other symptoms may include weight gain, frothy urine, and susceptibility to infections. Hematuria, hyperlipidemia, and hypertension are not typical features of nephrotic syndrome in children.
