1. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?
- A. Diarrhea
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.
2. The mother of a newborn infant with hypospadias asks the nurse why circumcision cannot be performed. Which is the most appropriate response by the nurse?
- A. Circumcision will cause an infection.
- B. Circumcision is not performed in a newborn.
- C. Circumcision will cause difficulty with urination.
- D. Circumcision has been delayed to save tissue for surgical repair.
Correct answer: D
Rationale: The reason circumcision is not performed in a newborn with hypospadias is that the dorsal foreskin tissue will be needed for the surgical repair of hypospadias. Delaying circumcision allows for the preservation of tissue that will be crucial for the corrective surgery. This surgical repair is typically done within the first year of life to minimize the psychological impact on the child. Choices A, B, and C are incorrect as they do not address the specific reason for delaying circumcision in this case.
3. The healthcare professional calculates the IV flow rate for a patient receiving an antibiotic. The patient is to receive 100mL of the antibiotic over 30 minutes. The IV infusion set has a drop factor of 10 drops per milliliter. How many drops per minute should the healthcare professional set the IV to deliver?
- A. 11
- B. 19
- C. 26
- D. 33
Correct answer: D
Rationale: To determine the drops per minute for the IV flow rate, you can use the formula: Drops Per Minute = (Milliliters to be infused x Drop Factor) / Time in Minutes. Substituting the given values, you get 100 mL x 10 drops/mL / 30 minutes = 33 drops per minute. Therefore, the correct answer is 33, as the healthcare professional should set the IV to deliver 33 drops per minute to infuse the antibiotic correctly. Choices A, B, and C are incorrect as they do not match the calculated drops per minute based on the provided values.
4. During an admission assessment on a 2-year-old child diagnosed with nephrotic syndrome, the nurse notes that which characteristic is most commonly associated with this syndrome?
- A. Hypertension
- B. Generalized edema
- C. Increased urinary output
- D. Frank, bright red blood in the urine
Correct answer: B
Rationale: Nephrotic syndrome in children is characterized by massive proteinuria, hypoalbuminemia, hyperlipidemia, and edema. The most common manifestation is generalized edema due to protein loss in the urine, leading to decreased plasma oncotic pressure. This results in fluid shifting into the interstitial spaces, causing edema. Hypertension is not a typical feature of nephrotic syndrome in children. Increased urinary output is not a common finding; instead, children with nephrotic syndrome often have decreased urine output due to decreased renal perfusion. The presence of frank, bright red blood in the urine is not a typical characteristic of nephrotic syndrome but may indicate a different renal condition such as glomerulonephritis.
5. The nurse is counting a client's respiratory rate. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. Which respiratory rate should the nurse document?
- A. 14
- B. 16
- C. 17
- D. 28
Correct answer: B
Rationale: The most accurate respiratory rate is the second count obtained by the nurse, which was not interrupted by coughing. The nurse counted eight respirations over 30 seconds, so doubling this count gives a respiratory rate of 16 breaths per minute. This calculation is based on the assumption that the client's breathing pattern remained relatively stable during the two 30-second intervals. Options A, C, and D are incorrect because they do not reflect the accurate count obtained without interruptions. Choice B (16) is the correct answer as it reflects the uninterrupted count of respirations by the nurse.
