A 7-year-old obese child was diagnosed at his 6-year primary care visit with idiopathic hypertension. The family was instructed to modify his diet and begin an exercise program to control the hypertension. At this visit, it was decided the child should begin a low dose of Lisinopril (Zestril) at 0.07 mg/kg/day. The child weighs 99 pounds. What is the correct dose for this child?
- A. 70 mg/day
- B. 30 mg/day
- C. 6 mg/day
- D. 3 mg/day
Correct Answer: D
Rationale: The correct dose for this child is 3 mg/day. To calculate the dose, we first need to convert the child's weight from pounds to kilograms by dividing by 2.2 (99 lbs / 2.2 = 45 kg). Next, we multiply the weight in kg by the prescribed dosage of 0.07 mg/kg/day (45 kg x 0.07 mg/kg/day = 3.15 mg/day). Since the dosing is typically rounded down for safety reasons, the correct dose is 3 mg/day.
Choice A (70 mg/day) is incorrect because it is too high for a child of this weight and could lead to adverse effects. Choice B (30 mg/day) is also too high. Choice C (6 mg/day) is incorrect as it does not reflect the calculated dosage based on the weight of the child. Therefore, the correct answer is D (3 mg/day) based on the calculated dosage per kg for this specific child.

Your patient has just returned from the OR following an arterial septal defect repair. You are reviewing your orders and question the fluid rate ordered. Your patient is 6 years old and weighs 50 pounds. Select the appropriate hourly maintenance fluid rate for your patient.
- A. 63 ml/hr
- B. 64 ml/hr
- C. 65 ml/hr
- D. 107 ml/hr
Correct Answer: A
Rationale: The appropriate hourly maintenance fluid rate for a 6-year-old patient weighing 50 pounds can be calculated using the Holliday-Segar method, which recommends 100 ml/kg/day for the first 10 kg of body weight, 50 ml/kg/day for the next 10 kg, and 20 ml/kg/day for each additional kg. Converting the patient's weight from pounds to kg (50 lbs / 2.2 = 22.73 kg), the calculation would be:
100 ml x 10 kg + 50 ml x 10 kg + 20 ml x 2.73 kg = 1000 ml + 500 ml + 54.6 ml = 1554.6 ml/day
To convert this to an hourly rate, divide by 24 hours: 1554.6 ml/day / 24 hours = 64.775 ml/hr, which rounds down to 63 ml/hr (Option A).

A child with a history of diabetes mellitus presents with sweating, confusion, and slurred speech. The nurse suspects the cause is:
- A. Hyperglycemia
- B. Hyperkalemia
- C. Hyponatremia
- D. Hypoglycemia
Correct Answer: D
Rationale: The correct answer is D: Hypoglycemia. In a child with a history of diabetes mellitus, sweating, confusion, and slurred speech indicate low blood sugar levels. Hypoglycemia can lead to neuroglycopenic symptoms like confusion and slurred speech. Hyperglycemia (choice A) would present with polyuria, polydipsia, and fruity breath. Hyperkalemia (choice B) can cause muscle weakness and cardiac arrhythmias. Hyponatremia (choice C) typically presents with weakness, fatigue, and confusion. In this case, the symptoms point towards hypoglycemia as the most likely cause.
The nurse is providing education to the parents of an infant with cradle cap. Which of the following statements by the parents indicates their understanding?
- A. We should use hydrogen peroxide as shampoo for my child until it is resolved
- B. We should expect that my child will probably have asthma & allergies too
- C. We should brush the loosened crusts out of the hair after shampooing
- D. We should decrease the frequency that I wash my child's hair to once a week
Correct Answer: C
Rationale: The correct answer is C: "We should brush the loosened crusts out of the hair after shampooing." This statement indicates understanding as brushing the loosened crusts helps to remove the scales and prevent further build-up. Hydrogen peroxide (A) is not recommended for cradle cap as it can irritate the skin. Asthma and allergies (B) are not directly related to cradle cap. Decreasing hair wash frequency to once a week (D) can worsen cradle cap by allowing build-up of oils and dead skin cells.
When instructing the parents of a toddler with iron deficiency anemia about the importance of increasing iron in the toddler's diet, which of the following foods should the nurse instruct the parents to include in the toddler's diet?
- A. Pasta
- B. Vitamin D milk
- C. Dried fruits
- D. Green leafy vegetables
Correct Answer: C
Rationale: The correct answer is C: Dried fruits. Dried fruits are a good source of iron, which is essential for treating iron deficiency anemia in toddlers. They provide a concentrated amount of iron in a small serving size, making them convenient for toddlers. Pasta (A) does not contain significant amounts of iron. Vitamin D milk (B) is important for bone health but does not provide a substantial amount of iron. Green leafy vegetables (D) are a good source of iron, but they may be harder for toddlers to eat compared to dried fruits.
A nurse is caring for a school-age child who is 2 hr postoperative following a cardiac catheterization. The nurse observes blood on the child's dressing. Which of the following actions should the nurse take?
- A. Apply intermittent pressure 2.5 cm (1 in) below the percutaneous skin site.
- B. Apply continuous pressure 2.5 cm (1 in) above the percutaneous skin site.
- C. Apply continuous pressure 2.5 cm (1 in) below the percutaneous skin site.
- D. Apply intermittent pressure 2.5 cm (1 in) above the percutaneous skin site.
Correct Answer: C
Rationale: Correct Answer: C
Rationale: Applying continuous pressure 2.5 cm below the percutaneous skin site will help control bleeding by promoting clot formation at the catheter insertion site. This pressure point is closer to the source of bleeding, ensuring better hemostasis and preventing further complications.
Summary:
A: Applying intermittent pressure below the site is incorrect as continuous pressure is more effective in achieving hemostasis.
B: Applying continuous pressure above the site is incorrect as it does not target the bleeding source directly.
D: Applying intermittent pressure above the site is incorrect as continuous pressure is preferred for controlling bleeding.
