CAT Exam Practice Test
1. What action should the nurse take after a client produces the first of a series of sputum samples for cytology?
- A. Ensure the client remains NPO until all samples are collected
- B. Transport the sputum container to the laboratory in a biohazard bag
- C. Discard the initial sample and document the time it was obtained
- D. Document the time the client last ate or drank on the laboratory slip
Correct answer: B
Rationale: The correct action for the nurse to take after a client produces the first of a series of sputum samples for cytology is to transport the sputum container to the laboratory in a biohazard bag. This is important to ensure proper handling and prevent contamination of the sample. Choice A is incorrect because there is no need to keep the client NPO until all samples are collected. Choice C is incorrect as the initial sample should not be discarded but rather transported to the laboratory. Choice D is also incorrect as documenting the time the client last ate or drank is not directly relevant to the immediate action needed for the sputum sample.
2. A client with chronic alcoholism is admitted with a decreased serum magnesium level. Which snack option should the nurse recommend to this client?
- A. Cheddar cheese and crackers
- B. Carrot and celery sticks
- C. Beef bologna sausage slices
- D. Dry roasted almonds
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.
3. A young adult woman visits the clinic and learns that she is positive for BRCA1 gene mutation and asks the nurse what to expect next. How should the nurse respond?
- A. Explain that counseling will be provided to give her information about her cancer risk.
- B. Gather additional information about the client’s family history for all types of cancer.
- C. Offer assurance that there are a variety of effective treatments for breast cancer.
- D. Provide information about survival rates for women who have this genetic mutation.
Correct answer: A
Rationale: The correct answer is A because counseling will help the woman understand her risk and options for surveillance or preventive measures. At this point, it is crucial to address the woman's immediate concerns related to the BRCA1 gene mutation. Choice B is incorrect as the focus should be on the woman's individual risk due to the specific gene mutation she carries. Choice C is not the priority as treatment options come after assessing the risk and deciding on surveillance or preventive measures. Choice D is incorrect because discussing survival rates is not the immediate need for someone who has just received information about having a genetic mutation.
4. The parents of a 6-year-old child recently diagnosed with Duchenne muscular dystrophy tell the nurse that their child wants to continue attending swimming classes. How should the nurse respond?
- A. Encourage the parents to allow the child to continue attending swimming lessons with supervision
- B. Suggest that the child be encouraged to participate in a team sport to promote socialization
- C. Explain that their child is not mature enough to understand the risks associated with swimming
- D. Provide a list of alternative activities that are less likely to cause the child to experience fatigue
Correct answer: A
Rationale: Encouraging the parents to allow the child to continue attending swimming lessons with supervision is the most appropriate response. Swimming can be beneficial for the child, providing both exercise and enjoyment. Supervision can help manage any risks associated with swimming. Choice B is incorrect because the child's preference for swimming should be respected, and swimming can still offer socialization opportunities. Choice C is incorrect as it undermines the child's capability to understand the situation. Choice D is less appropriate as it does not address the child's interest in swimming and may limit beneficial physical activity.
5. A new mother asks the nurse if the newborn infant has an infection because the healthcare provider prescribed a blood test called the TORCH screen test. Which response should the nurse offer to the mother's inquiry?
- A. Rising titers identify the etiology of certain neuro-sensory birth defects
- B. The screen determines the risk for inherited anomalies in the newborn
- C. The test identifies the correct antibiotic to give the newborn for an infection
- D. Exposure to infections that can cross the placenta cause a positive antibody titer
Correct answer: D
Rationale: The TORCH screen test is used to detect infections that can affect the newborn by showing if there was exposure to these infections. Choice A is incorrect because the TORCH screen test is not specifically for identifying the etiology of neuro-sensory birth defects. Choice B is incorrect because the test does not determine the risk for inherited anomalies. Choice C is incorrect because the test is not used to identify the correct antibiotic for an infection, but rather to detect infections that may have affected the newborn.
