1. Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?

• A. Increased blood pressure
• B. A sunken fontanel
• C. Decreased pulse rate
• D. Low urine specific gravity

Correct answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

2. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

3. A child is admitted to the hospital with acute renal failure. The parents ask about the prognosis for acute renal failure. The nurse’s response should be based on which statement about acute renal failure?

• A. Children with acute renal failure will have to take prophylactic antibiotics for life.
• B. Acute renal failure always leads to chronic renal failure.
• C. Acute renal failure may be reversible.
• D. All children with acute renal failure will eventually need a kidney transplant.

Correct answer: C

Rationale: The correct answer is C: Acute renal failure in children is often reversible, especially when the underlying cause is identified and treated promptly. It does not always lead to chronic renal failure or the need for a kidney transplant. Choice A is incorrect as prophylactic antibiotics for life are not a standard treatment for acute renal failure. Choice B is incorrect as acute renal failure does not always progress to chronic renal failure. Choice D is incorrect as not all children with acute renal failure will eventually require a kidney transplant.

4. Prior to giving a hospitalized pre-schooler an injection, the nurse gives the child’s teddy bear a “shot” first. This method is known as:

• A. Critical play
• B. Role play
• C. Diversionary activity
• D. Dramatic play

Correct answer: D

Rationale: The correct answer is D: Dramatic play. Dramatic play involves children acting out experiences to better understand them and reduce fear. In this scenario, by giving the teddy bear a 'shot' first, the nurse is engaging in dramatic play to help the child comprehend and feel more comfortable with the upcoming injection.\n A: Critical play involves critical thinking and problem-solving, not acting out scenarios.\n B: Role play typically involves pretending to be someone else, not necessarily acting out a specific experience.\n C: Diversionary activity aims to distract or redirect attention, which is different from the purpose of dramatic play in this context.

5. What is the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?

• A. The medication reduces gastric acid secretion.
• B. The medication neutralizes the acid in the stomach.
• C. The medication increases the rate of gastric emptying time.
• D. The medication coats the lining of the stomach and esophagus.

Correct answer: A

Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.
