RN Nursing Care of Children 2019 With NGN
1. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?
- A. Bronchodilation, muscle relaxation, and decreased mucus production
- B. Air trapping and hypo-inflation of the alveoli
- C. Air trapping and decreased blood flow to the upper airway
- D. Bronchoconstriction, airway inflammation, and excess mucus production
Correct answer: D
Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.
2. In which type of cancer are the urinary excretion of the breakdown products of catecholamines, especially vanillylmandelic acid (VMA) and homovanillic acid (HVA), detected?
- A. Neuroblastoma
- B. Nephroblastoma
- C. Leukemia
- D. Osteosarcoma
Correct answer: A
Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.
3. A six-year-old child is admitted to the hospital with a diagnosis of urinary tract infection. Which of these factors contribute to urinary tract infections in young children?
- A. Excessive intake of carbonated beverages.
- B. Insufficient water intake to flush the kidneys.
- C. Voiding pattern of 5-6 times a day.
- D. Infrequent voiding which results in urinary stasis.
Correct answer: D
Rationale: Infrequent voiding can lead to urinary stasis, which increases the risk of urinary tract infections by allowing bacteria to multiply in the bladder. Encouraging regular voiding and proper hydration can help prevent UTIs. Choices A, B, and C are incorrect. Excessive intake of carbonated beverages may irritate the bladder but is not a direct cause of UTIs. Insufficient water intake can concentrate urine but does not necessarily lead to infections. A voiding pattern of 5-6 times a day is within the normal range and is not associated with increased UTI risk.
4. An infant, age 6 months, has six teeth. The nurse should recognize that this is what?
- A. Normal tooth eruption
- B. Delayed tooth eruption
- C. Unusual and dangerous
- D. Earlier than expected tooth eruption
Correct answer: D
Rationale: Having six teeth at 6 months is earlier than the typical tooth eruption schedule, but it is not unusual or dangerous. It is within the range of normal variations in infant development.
5. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic shock
- B. Cardiogenic shock
- C. Hypovolemic shock
- D. Anaphylactic shock
Correct answer: D
Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.
