A 7-year-old is admitted to the hospital with persistent vomiting, and a nasogastric tube attached to low intermittent suction is applied. Which finding is most important for the nurse to report to the healthcare provider?

Correct Answer: C

Rationale: A serum potassium level of 3.0 mEq/L is significantly low and indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Therefore, it is crucial for the nurse to report this finding promptly to the healthcare provider for immediate intervention. The other findings are not as critical in this situation. Gastric output of 100 mL in the last 8 hours may be expected in a patient with persistent vomiting. The shift intake of IV fluids and ice chips indicates fluid replacement, which is important but not as urgent as correcting electrolyte imbalances. A serum pH of 7.45 is within the normal range and does not indicate an immediate concern.

Correct Answer: B

Rationale: Inquiring about the use of alternative treatment methods is essential to understand cultural practices and provide holistic care. It allows the nurse to gather more information about the blemishes and potentially uncover traditional or alternative healing approaches that the family may have used. This approach demonstrates cultural sensitivity and a comprehensive assessment before making assumptions or taking further actions. Identifying the antibiotics used for treating pneumonia (Choice A) is not immediately necessary in this context as the focus is on the blemishes. Asking about a recent accident (Choice C) assumes a traumatic cause without evidence. Reporting suspected child abuse (Choice D) is premature without further assessment or evidence of abuse.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants is an effective measure to prevent tick bites, which can transmit Lyme disease. Ticks are commonly found in wooded areas and tall grass, so covering exposed skin helps reduce the risk of tick bites and subsequently lowers the risk of contracting Lyme disease. Choices A, B, and C do not directly address the mode of transmission of Lyme disease. Option A pertains to respiratory protection against dust, Option B focuses on wound care, and Option C relates to water safety, none of which are directly related to preventing Lyme disease transmission.

Correct Answer: C

Rationale: Neurological soft signs in children often manifest as poor coordination and a sense of position. These signs can indicate underlying neurological issues and are important to assess in pediatric patients. Choices A, B, and D are less likely to be associated with neurological soft signs in children. Inability to move the tongue in a specific direction may suggest a cranial nerve dysfunction rather than general neurological soft signs. Presence of vertigo is more related to inner ear disturbances or vestibular issues. Loss of visual acuity may indicate problems with the eyes rather than general neurological soft signs.

Correct Answer: A

Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg · 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.
