CAT Exam Practice Questions
Question 1 of 5
When caring for a laboring client whose contractions are occurring every 2-3 minutes, the nurse should document that the pump is infusing how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number. Click on each chart tab for additional information. Please be sure to scroll to the bottom right corner of each tab to view all information contained in the client's medical record.)
Correct Answer: A
Rationale: The correct infusion rate can be calculated based on the information provided in the chart. With contractions occurring every 2-3 minutes, the recommended infusion rate is 5 ml/hr. This rate ensures proper hydration and medication delivery to support the client during labor. Choices B, C, and D are incorrect as they do not align with the calculated rate based on the contractions frequency and the client's needs.
Question 2 of 5
For a client with pneumonia, the prescription states, "Oxygen at liters/min per nasal cannula PRN difficult breathing." Which nursing intervention is effective in preventing oxygen toxicity?
Correct Answer: A
Rationale: Choice A is the correct answer because prolonged exposure to high levels of oxygen can lead to oxygen toxicity. Administering oxygen at high levels for extended periods can overwhelm the body's natural defenses against high oxygen levels, causing toxicity. Choices B, C, and D are incorrect. Choice B is unrelated to preventing oxygen toxicity. Choice C is unsafe as removing the nasal cannula can deprive the client of necessary oxygen. Choice D, running oxygen through a hydration source, is not a standard practice for preventing oxygen toxicity.
Question 3 of 5
The healthcare provider believes that a client who frequently requests pain medication may have a substance abuse problem. Which intervention reflects the healthcare provider's value of client autonomy over veracity?
Correct Answer: A
Rationale: Administering the prescribed analgesic when requested is the most appropriate intervention that reflects the healthcare provider's value of client autonomy over veracity. This action respects the client's right to manage their pain and avoids deception. Referring the client to a substance abuse program (Choice B) assumes a diagnosis without evidence and does not respect the client's autonomy. Collaborating to provide a placebo (Choice C) would involve deception, which goes against the value of veracity. Documenting the frequency of medication requests (Choice D) is important for the client's care but does not directly address the issue of respecting client autonomy over veracity.
Question 4 of 5
A client with type 2 diabetes mellitus is admitted for antibiotic treatment of a leg ulcer. Which signs and symptoms, indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), should the nurse report to the healthcare provider? (Select all that apply.)
Correct Answer: A
Rationale: The correct signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) include increased heart rate, visual disturbances, and decreased mentation. These symptoms are often associated with HHNS due to the high blood glucose levels. Uremic frost, a sign of advanced kidney disease, is not typically associated with HHNS. Therefore, choices B and D are incorrect. However, choice C, 'Presence of uremic frost,' is incorrect as it is not typically associated with HHNS.
Question 5 of 5
A client with a BMI of 60.2 kg/m² is admitted to the intensive care unit 3 weeks after gastric bypass with gastric rupture and impending multiple organ dysfunction syndrome (MODS). What should the nurse prepare to implement first?
Correct Answer: A
Rationale: In this critical situation with gastric rupture and impending MODS, the priority intervention should be mechanical ventilation. This client is at risk of respiratory compromise due to the severity of the condition. Platelet transfusion (Choice B) is not the priority as there is no indication of significant bleeding. Loop diuretic therapy (Choice C) and cyanocobalamin administration (Choice D) are not the immediate priorities in this scenario and would not address the urgent need for respiratory support.
