CAT Exam Practice Questions
Question 1 of 9
An adult client presents to the clinic with large draining ulcers on both lower legs that are characteristic of Kaposi's Sarcoma lesions. The client is accompanied by two family members. What action should the nurse take?
Correct Answer: C
Rationale: In this scenario, the most appropriate action for the nurse to take is to complete a head-to-toe assessment to identify other signs of HIV. Kaposi's Sarcoma is commonly associated with HIV infection, and conducting a comprehensive assessment can provide crucial information on potential signs and symptoms related to HIV. This information is essential for providing appropriate care and treatment. Option A is not the priority at this moment, as the focus should be on assessing the client comprehensively first. Sending the family members away (Option B) may not be necessary if they are not interfering with the assessment process. While infection control is important, asking the family members to wear gloves (Option D) is not the most critical action to take in this situation.
Question 2 of 9
A client with acute renal failure (ARF) is admitted for uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale. Which intervention is the most important for the nurse to include in this client's plan of care?
Correct Answer: A
Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client's cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
Question 3 of 9
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 4 of 9
A 3-year-old boy was successfully toilet trained prior to his admission to the hospital for injuries sustained from a fall. His parents are very concerned that the child has regressed in his toileting behaviors. Which information should the nurse provide to the parents?
Correct Answer: A
Rationale: Children often regress in toileting behaviors during hospitalization due to stress and changes in routine. However, they usually resume normal behaviors once they are discharged and back in their familiar environment. Providing reassurance to the parents that the child is likely to return to his previous toileting habits after leaving the hospital can help alleviate their concerns. Choices B, C, and D are incorrect because they do not address the normal pattern of behavior regression and recovery in toileting skills associated with hospitalization.
Question 5 of 9
When gathering subjective data from a client, what intervention should the nurse implement first?
Correct Answer: B
Rationale: Establishing rapport is the initial step the nurse should take when gathering subjective data from a client. Building trust and a good relationship with the client creates an environment where the client feels comfortable sharing accurate and honest information. Listening attentively is important but should come after rapport is established to enhance active listening. Listing problems and clarifying inferences are actions that occur later in the assessment process, after the nurse has established a good rapport and obtained a comprehensive understanding of the client's perspective. Therefore, option B is the correct answer.
Question 6 of 9
In what order should the nurse assess a lethargic one-hour-old infant brought to the nursery?
Correct Answer: D
Rationale: When assessing a lethargic one-hour-old infant, the nurse should prioritize assessing the most critical parameters first. Temperature and heart rate are vital signs that provide immediate information about the infant's well-being. Therefore, the correct order of assessment should be temperature, heart rate, respirations, and then a heel stick. Temperature is crucial to determine if the infant is hypothermic or hyperthermic, while heart rate gives insight into the circulatory system's function. Respirations follow to evaluate the infant's breathing pattern. Lastly, the heel stick is important for certain screenings but is not as urgent as evaluating temperature and heart rate in a lethargic infant.
Question 7 of 9
A client with chronic alcoholism is admitted with a decreased serum magnesium level. Which snack option should the nurse recommend to this client?
Correct Answer: D
Rationale: Dry roasted almonds are the most suitable snack option for a client with chronic alcoholism and a decreased serum magnesium level because they are high in magnesium. Magnesium is essential in addressing the deficiency. Cheddar cheese and crackers (Choice A) do not contain as much magnesium as almonds. Carrot and celery sticks (Choice B) are healthy choices but do not provide a significant amount of magnesium. Beef bologna sausage slices (Choice C) are not a good choice as processed meats are not rich in magnesium.
Question 8 of 9
A client has had several episodes of clear, watery diarrhea that started yesterday. What action should the nurse implement?
Correct Answer: D
Rationale: The correct action for the nurse to implement in a client experiencing clear, watery diarrhea is to review the client's current list of medications. Certain medications can cause diarrhea as a side effect, so identifying any potential culprits is essential. Administering an antiemetic (Choice A) is not appropriate for diarrhea, as antiemetics are used to control nausea and vomiting, not diarrhea. Assessing for hemorrhoids (Choice B) is not the priority when the client is experiencing watery diarrhea; addressing the root cause is crucial. Checking the client's hemoglobin level (Choice C) is not the immediate action needed for this situation as it does not directly address the cause of diarrhea.
Question 9 of 9
Which type of wound would most likely require immediate intervention by the healthcare provider?
Correct Answer: A
Rationale: A laceration would most likely require immediate intervention by the healthcare provider due to its deeper tissue damage, significant bleeding, and higher risk of infection compared to abrasions, contusions, and ulcerations. Lacerations often need prompt attention to control bleeding, clean the wound, and reduce the risk of infection. Abrasions are superficial wounds that usually do not require urgent attention as they tend to heal well on their own with basic wound care. Contusions are bruises that typically resolve on their own without immediate intervention. Ulcerations are open sores that may require intervention but not necessarily immediate action unless complicated by infection or other issues.
