Nursing Elites

1. When assessing a child admitted to the hospital with pyloric stenosis, which symptom would the nurse likely find when asking the parent about the child's symptoms?

• A. Watery diarrhea
• B. Projectile vomiting
• C. Increased urine output
• D. Vomiting large amounts of bile

Correct answer: B

Rationale: In pyloric stenosis, hypertrophy of the circular muscles of the pylorus causes narrowing of the pyloric canal between the stomach and the duodenum. The hallmark symptom of pyloric stenosis is projectile vomiting, which is the forceful expulsion of stomach contents. Other common symptoms include irritability, hunger and crying, constipation, and signs of dehydration. Watery diarrhea (Choice A) is not a typical symptom of pyloric stenosis. Increased urine output (Choice C) is not directly associated with this condition. Vomiting large amounts of bile (Choice D) is not a characteristic symptom of pyloric stenosis; instead, the vomitus in pyloric stenosis is non-bilious.

2. The physician has decided to perform a thoracentesis based on Mr. R's assessment. Which of the following actions from the nurse is most appropriate?

• A. Instruct the client not to talk during the procedure
• B. Assist the client to sit upright or slightly lean forward
• C. Insert a 20-gauge needle just above the 4th intercostal space
• D. Connect the needle to suction to remove fluid that has collected in the pleural space

Correct answer: A

Rationale: The correct answer is to instruct the client not to talk during the procedure. This is important to prevent air from being drawn into the pleural space during the thoracentesis. Choice B is incorrect because the client should be sitting upright or slightly leaning forward during the procedure to facilitate access to the pleural space. Choice C is incorrect as the nurse should not perform the thoracentesis procedure, which involves inserting a needle into the pleural space - this is the physician's responsibility. Choice D is incorrect as connecting the needle to suction to remove fluid is not the appropriate procedure for a thoracentesis. Thoracentesis is typically done to remove fluid or air for diagnostic or therapeutic purposes, not to connect to suction to remove fluid that has collected in the pleural space.

3. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

4. A child is seen in the emergency department for scarlet fever. Which of the following descriptions of scarlet fever is not correct?

• A. Scarlet fever is caused by infection with group A Streptococcus bacteria.
• B. "Strawberry tongue"? is a characteristic sign.
• C. Petechiae occur on the soft palate.
• D. The pharynx is red and swollen.

Correct answer: C

Rationale: Petechiae on the soft palate are not a typical finding in scarlet fever. Scarlet fever is caused by group A Streptococcus bacteria, often presenting with a strawberry tongue, red and swollen pharynx, and a sandpaper-like rash. The presence of petechiae on the soft palate is more commonly associated with conditions like rubella rather than scarlet fever. Therefore, this description is not correct in the context of scarlet fever.

5. A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?

• A. Peritonitis
• B. Appendicitis
• C. Intussusception
• D. Hirschsprung's disease

Correct answer: B

Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
