You are the nurse caring for a 3-year-old, 33-pound child on digoxin. The safe dose range for digoxin is 20-40 mcg/kg/day. The order is for digoxin to be given IV every 12 hours, what is the maximum safe single dose the child should receive?
- A. 300 mcg
- B. 600 mcg
- C. 660 mcg
- D. 1320 mcg
Correct Answer: A
Rationale: The correct answer is A: 300 mcg. To determine the maximum safe single dose, we first need to calculate the total daily safe dose range for the child. The child's weight is 33 pounds, which is approximately 15 kg (1 kg = 2.2 lbs). The safe dose range is 20-40 mcg/kg/day, so for a 15 kg child, the total daily safe dose range would be 300-600 mcg/day. Since the medication is given every 12 hours, the maximum safe single dose would be half of the total daily dose, which is 300 mcg. This ensures that the child stays within the safe dose range for digoxin. Choice B (600 mcg) exceeds the maximum daily safe dose, choice C (660 mcg) exceeds the daily safe dose range, and choice D (1320 mcg) is way above the safe dose range for the child's weight.

A child admitted with extensive burns. The nurse notes that there are burns on the child's lips and singed nasal hairs. The nurse should suspect that the child has a(n):
- A. Chemical burn
- B. Inhalation injury
- C. Electrical burn
- D. Hot-water scald
Correct Answer: B
Rationale: The correct answer is B: Inhalation injury. The presence of burns on the lips and singed nasal hairs indicate that the child has likely inhaled hot gases or smoke, which can cause damage to the respiratory tract. This is a common finding in cases of inhalation injury resulting from exposure to fire or smoke. Inhalation injury can lead to airway compromise, respiratory distress, and other serious complications. The other choices (A: Chemical burn, C: Electrical burn, D: Hot-water scald) do not specifically indicate damage to the respiratory tract, making them less likely in this scenario.
The expected finding of Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) include:
- A. Low urine output & increased levels of antidiuretic hormone
- B. Low urine output & decreased levels of antidiuretic hormone
- C. Increased urine output & decreased levels of antidiuretic hormone
- D. Increased urine output & increased levels of antidiuretic hormone
Correct Answer: A
Rationale: The correct answer is A: Low urine output & increased levels of antidiuretic hormone. In SIADH, there is an excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. This results in low urine output as the body retains water. Increased levels of ADH cause the kidneys to reabsorb more water, further contributing to low urine output. The other choices are incorrect because in SIADH, urine output is typically low, and ADH levels are elevated due to the dysregulation of the feedback mechanism that controls ADH release. Increased urine output and decreased levels of ADH (choice C) would be more indicative of diabetes insipidus, a condition characterized by decreased ADH production or kidney insensitivity to ADH.
A child being administered a new medication displays signs of an adverse drug reaction. The nurse would expect treatment of the reaction to include (Select all that apply):
- A. Administering antibiotics
- B. Discontinuing the drug
- C. Administering antihistamines
- D. Administering corticosteroids
Correct Answer: B,C,D
Rationale: The correct answer is B, C, and D. Discontinuing the drug is essential to stop the adverse reaction. Administering antihistamines helps manage symptoms like itching and hives. Corticosteroids can reduce inflammation and allergic responses caused by the reaction. Antibiotics (choice A) are not indicated unless there is a specific infection requiring treatment. No other choices were provided, but it's crucial to focus on stopping the offending drug, managing symptoms, and addressing inflammation in the case of an adverse drug reaction.
A nurse is caring for a baby that may have sickle cell disease. Which of the following tests should be performed to distinguish sickle cell trait from sickle cell disease?
- A. Hemoglobin electrophoresis
- B. Sickle solubility test
- C. Complete Blood Count (CBC)
- D. International Normalized Ratio (INR)
Correct Answer: A
Rationale: The correct answer is A: Hemoglobin electrophoresis. This test is used to distinguish sickle cell trait from sickle cell disease by separating different types of hemoglobin based on their electrical charge. Sickle cell trait will show a different hemoglobin pattern compared to sickle cell disease.
B: Sickle solubility test is not specific enough to differentiate between sickle cell trait and disease.
C: Complete Blood Count (CBC) provides general information about blood cells but does not specifically differentiate between sickle cell trait and disease.
D: International Normalized Ratio (INR) is used to monitor blood clotting and is not relevant for distinguishing sickle cell trait from disease.
A nurse is preparing to perform a dressing change on a 6-year-old child with mild cognitive impairment (CI) who sustained a minor burn. Which strategy should the nurse use to prepare the child for this procedure?
- A. Verbally explain what will be done
- B. Have the child watch a video on dressing change
- C. Demonstrate a dressing change on a doll
- D. Explain the importance of keeping the burn area clean
Correct Answer: C
Rationale: The correct answer is C: Demonstrate a dressing change on a doll. This strategy is most appropriate because children with cognitive impairment often benefit from visual aids and hands-on experiences. By demonstrating the dressing change on a doll, the nurse can provide a clear and concrete example for the child to understand what will happen during the procedure. This approach can help reduce anxiety and fear by making the process more tangible and relatable for the child.
Other choices are incorrect:
A: Verbally explaining may not be as effective for a child with cognitive impairment who may struggle to understand complex verbal instructions.
B: Watching a video may be overwhelming or confusing for the child with cognitive impairment.
D: Explaining the importance of keeping the burn area clean is important but may not adequately prepare the child for the procedure itself.
