1. The healthcare professional is assessing a 4-year-old client. Which finding suggests to the healthcare professional this child may have a genetic disorder?
- A. Inquiry reveals the child had feeding problems.
- B. The child weighs 40 lb (18.2 kg) and is 40 in (101.6 cm) in height.
- C. The child has low-set ears with lobe creases.
- D. The child can hop on one foot but cannot skip.
Correct answer: C
Rationale: Low-set ears with lobe creases are often associated with genetic disorders and can indicate underlying chromosomal abnormalities. This physical characteristic is known to be a common sign in various syndromes like Down syndrome. Choices A, B, and D are not directly linked to genetic disorders. Feeding problems and specific weight/height measurements are more general indicators of growth and development, while the ability to hop on one foot but not skip is a developmental milestone assessment that does not specifically point towards a genetic disorder.
2. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?
- A. Chest X-ray
- B. Sweat chloride test
- C. Pulmonary function test
- D. Sputum culture
Correct answer: B
Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.
3. A child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?
- A. A weak radial pulse
- B. An irregular heartbeat
- C. A bounding femoral pulse
- D. An elevated radial blood pressure
Correct answer: A
Rationale: When a child has coarctation of the aorta, the nurse would expect to identify a weak radial pulse when taking the child's vital signs. Coarctation of the aorta results in a narrowing of the aorta, leading to reduced blood flow and a weakened pulse. An irregular heartbeat (Choice B) is less likely to be associated with coarctation of the aorta. Similarly, a bounding femoral pulse (Choice C) is not typically observed with this condition. An elevated radial blood pressure (Choice D) is less common as coarctation of the aorta usually causes decreased blood pressure in the lower extremities due to the aortic narrowing.
4. A parent calls the outpatient clinic requesting information about the appropriate dose of acetaminophen for a 16-month-old child who has signs of an upper respiratory tract infection and fever. The directions on the bottle of acetaminophen elixir are 120 mg every 4 hours when needed. At the toddler’s 15-month visit, the healthcare provider prescribed 150 mg. What is the nurse’s best response to the parent?
- A. “The dose is close enough, and it doesn’t really matter which one is given.”
- B. “From your description, the medication is not necessary. It should be avoided at this age.”
- C. “It is appropriate to use dosages based on age. Children typically have weights consistent for their age groups.”
- D. “The prescribed dose of the drug was based on weight, and this is a more accurate way of determining a therapeutic dose.”
Correct answer: D
Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing accounts for individual variations in drug metabolism and distribution, ensuring a more precise and safer medication administration. Choices A, B, and C are incorrect as they do not address the importance of weight-based dosing in children, potentially leading to inappropriate dosing and safety concerns.
5. Surgical repair for patent ductus arteriosus (PDA) is done to prevent the complication of
- A. pulmonary infection
- B. right-to-left shunt of blood
- C. decreased workload on left side of the heart
- D. increased pulmonary vascular congestion
Correct answer: D
Rationale: The correct answer is D: increased pulmonary vascular congestion. Surgical repair of patent ductus arteriosus (PDA) aims to prevent the complications associated with increased pulmonary vascular congestion, such as pulmonary hypertension and heart failure. Choice A, pulmonary infection, is not a direct complication of PDA but can occur secondary to other conditions. Choice B, right-to-left shunt of blood, is a feature of some congenital heart defects but not a direct complication of PDA. Choice C, decreased workload on the left side of the heart, is not a primary reason for surgical repair of PDA, as the main concern is the impact on pulmonary circulation.
