A child has a postoperative appendectomy incision covered by a dressing. The nurse has just completed a prescribed dressing change for this child. Which description is an accurate documentation of this procedure?

Correct Answer: C

Rationale: Option C provides a thorough and accurate documentation of the dressing change procedure for the postoperative appendectomy incision. This documentation includes essential details such as the condition of the incision site (non-reddened, sutures intact, no drainage noted on old dressing), the action taken (new dressing applied), and the outcome (procedure tolerated well by the child). It covers all the necessary aspects of the dressing change procedure and clearly indicates the status of the incision site before and after the intervention. Options A, B, and D do not provide as comprehensive and detailed information about the dressing change procedure and its outcomes, making option C the most appropriate choice for accurate documentation.

Correct Answer: A

Rationale: Imipramine (Tofranil) is a tricyclic antidepressant (TCA) that is commonly used to treat enuresis in children. Enuresis is a condition characterized by involuntary urination, especially observed during sleep in children who are old enough to have bladder control. Imipramine works by affecting the balance of certain neurotransmitters in the brain, which helps regulate the bladder and reduce involuntary urination. While imipramine has antidepressant properties, it is also effective in treating enuresis by reducing the frequency of bedwetting episodes.

Correct Answer: A

Rationale: Methylphenidate (Ritalin) is a stimulant medication commonly used in the treatment of ADHD. One of the possible side effects of methylphenidate is an increase in nervousness or jitteriness. This side effect is more common at the beginning of treatment or when the dosage is increased. It is important for parents to be aware of this potential side effect and to inform the healthcare provider if it becomes bothersome for the child. Other common side effects of methylphenidate may include decreased appetite, insomnia, and stomach upset.

Correct Answer: C

Rationale: Creatinine is a waste product produced by muscle metabolism that is normally filtered by the glomerulus in the kidneys and excreted in urine. The level of creatinine in the urine is a direct reflection of the glomerular filtration rate (GFR). As GFR decreases in conditions such as acute renal failure, the amount of creatinine excreted in the urine also decreases. Therefore, measuring creatinine levels in the urine is a useful clinical indication of the glomerular filtration rate and kidney function. pH, osmolality, and protein level may provide additional information but are not as directly linked to GFR as creatinine levels.

Correct Answer: D

Rationale: Hyperkalemia is a condition characterized by elevated levels of potassium in the blood. This can have serious effects on the heart, leading to cardiac arrhythmias which can be life-threatening. In acute renal failure, the kidneys are not able to properly regulate potassium levels in the blood, leading to a potential buildup of potassium, resulting in hyperkalemia. The nurse should recognize cardiac arrhythmias as a critical sign of hyperkalemia in a child with acute renal failure and take prompt action to address this electrolyte imbalance. Dyspnea, seizure, and oliguria are not typically directly correlated with hyperkalemia.
