A nurse is teaching the guardian of a newborn about car seat safety. Which of the following statements by the guardian indicates an understanding of the teaching?

A. Wire cutters:
Wire cutters are typically not necessary for postoperative care following a thoracotomy with chest tube placement. They are more commonly used in situations such as removing orthopedic hardware or cutting wires in emergency situations. Therefore, wire cutters are not essential equipment for this particular procedure.

B. Montgomery straps:
Montgomery straps are adhesive strips used to secure dressings or bandages without the need for tape. While they can be useful in some postoperative situations, they are not specifically required for a thoracotomy with chest tube placement.

C. Tracheostomy tray:

A tracheostomy tray contains equipment necessary for performing tracheostomy care, such as sterile gloves, tracheostomy tubes, and suctioning equipment. It is not directly related to thoracotomy or chest tube care post op.

D. Padded clamp:
A padded clamp, or chest tube holder, is a device used to secure chest tubes in place and prevent them from being accidentally dislodged. It is an essential piece of equipment for postoperative care following a thoracotomy with chest tube placement, as it helps maintain the integrity of the chest tubes and prevents complications such as air leaks or pneumothorax.

A. Decreased impulsiveness: Methylphenidate is a central nervous system stimulant commonly used to treat attention deficit hyperactivity disorder (ADHD) in children. One of the therapeutic effects of methylphenidate is the reduction of impulsiveness, hyperactivity, and inattention, which are hallmark symptoms of ADHD. Therefore, a decrease in impulsiveness would indicate that the medication is effective.
B. Increased urine output: Methylphenidate is not expected to affect urine output. Increased urine output is not a typical finding indicating the effectiveness of methylphenidate.
C. Increased appetite: Methylphenidate commonly causes appetite suppression as a side effect. Therefore, an increase in appetite would not be indicative of the medication's effectiveness. In fact, a decrease in appetite is a common adverse effect of methylphenidate.
D. Decreased abdominal pain: Methylphenidate is not typically used to treat abdominal pain, and its effectiveness is not evaluated based on the relief of abdominal pain. The primary therapeutic effect of methylphenidate in ADHD is the improvement of attention, focus, and impulse control. Therefore, decreased abdominal pain would not be a reliable indicator of the medication's effectiveness.
