1. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?
- A. Diarrhea
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.
2. When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?
- A. Rapid bronchospasms
- B. Inflammatory epithelial lesions
- C. Increased secretions
- D. Increased mucosal edema
Correct answer: A
Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
3. Which of the following statements best describes postural drainage as part of chest physiotherapy?
- A. Tapping on the chest wall to loosen secretions
- B. Squeezing the abdomen to increase expansion of the upper chest
- C. Using gravity to move secretions in the lung tissue
- D. Dilating the trachea to facilitate better release of secretions
Correct answer: C
Rationale: Postural drainage is a technique used in chest physiotherapy for clients with accumulated lung secretions. It involves positioning the client to utilize gravity in moving secretions from the lungs. Choice A, tapping on the chest wall, describes percussion, not postural drainage. Choice B, squeezing the abdomen, is not a correct description of postural drainage. Choice D, dilating the trachea, is not related to postural drainage but may be associated with airway clearance techniques.
4. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?
- A. Administer 30 Units of Lantus Daily
- B. CT of the spine with contrast
- C. X-ray of the abdomen and chest
- D. Administer heparin subcutaneously 5,000 Units every 12 hours
Correct answer: B
Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
5. The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?
- A. Neurotoxicity
- B. Hepatomegaly
- C. Nephrotoxicity
- D. Ototoxicity
Correct answer: C
Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.
