1. A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?
- A. Acidosis
- B. Alkalosis
- C. Hyperkalemia
- D. Hypernatremia
Correct answer: B
Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.
2. A group of nursing students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?
- A. Regulation of water balance
- B. Hormonal secretion
- C. Cellular metabolism
- D. Growth stimulation
Correct answer: B
Rationale: The correct answer is 'Hormonal secretion' (Choice B). The primary function of the endocrine system is to secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction. Choice A, 'Regulation of water balance,' is primarily controlled by the kidneys and the urinary system, not the endocrine system. Choice C, 'Cellular metabolism,' is more directly related to the functions of individual cells rather than the overall function of the endocrine system. Choice D, 'Growth stimulation,' is a function that can be influenced by hormones secreted by the endocrine system, but it is not the primary function of the system.
3. What information would the nurse include in the preoperative plan of care for an infant with myelomeningocele?
- A. Positioning the infant supine with a pillow under the buttocks
- B. Covering the sac with saline-soaked nonadhesive gauze
- C. Wrapping the infant snugly in a blanket
- D. Applying a diaper to prevent fecal soiling of the sac
Correct answer: B
Rationale: The correct answer is B: Covering the sac with saline-soaked nonadhesive gauze. This intervention is essential in caring for an infant with myelomeningocele as it helps prevent infection and maintains a moist environment around the sac before surgical repair. Positioning the infant supine with a pillow under the buttocks (Choice A) may be suitable for comfort but is not directly related to managing the myelomeningocele. Wrapping the infant snugly in a blanket (Choice C) and applying a diaper (Choice D) are not recommended as they can increase the risk of infection and damage to the sac.
4. The nurse is caring for a 15-year-old boy who has sustained burn injuries. The nurse observes the burn developing a purplish color with discharge and a foul odor. The nurse suspects which infection?
- A. Burn wound cellulitis.
- B. Invasive burn cellulitis.
- C. Burn impetigo.
- D. Staphylococcal scalded skin syndrome.
Correct answer: B
Rationale: Invasive burn cellulitis is characterized by the burn developing a dark brown, black, or purplish color with discharge and a foul odor. This description aligns with the symptoms observed in the 15-year-old boy. Burn wound cellulitis (Choice A) typically presents with erythema, edema, warmth, and tenderness at the burn site, without the characteristic changes seen in this case. Burn impetigo (Choice C) is a superficial infection characterized by honey-colored crusts, not consistent with the purplish color and foul odor described. Staphylococcal scalded skin syndrome (Choice D) is a condition caused by exotoxins produced by Staphylococcus aureus, leading to widespread desquamation of the skin, but it does not typically present with the specific findings mentioned in the scenario.
5. A 4-year-old child is admitted with a diagnosis of bacterial pneumonia. What is the priority nursing intervention?
- A. Administering antipyretics
- B. Administering antibiotics
- C. Monitoring fluid intake
- D. Providing nutritional support
Correct answer: B
Rationale: The priority nursing intervention for a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are essential to treat the infection, prevent its spread, and avoid potential complications. Administering antipyretics (Choice A) may help reduce fever but does not address the underlying cause of pneumonia, which is bacterial in this case. Monitoring fluid intake (Choice C) is important to maintain hydration but does not directly treat the infection. Providing nutritional support (Choice D) is crucial for overall health, but the immediate priority is to address the bacterial infection with antibiotics to prevent further complications and promote recovery.
