CAT Exam Practice Test Questions
Question 1 of 5
The nurse is teaching a class on child care to new parents. Which instruction should be included about the prevention of rotavirus infection in infants who are starting to eat foods?
Correct Answer: D
Rationale: The correct answer is D: Wash hands before any food preparation. Rotavirus is a highly contagious virus that can be prevented by maintaining proper hygiene. Washing hands before handling food can help prevent the spread of infections, including rotavirus. Choices A, B, and C are incorrect because while they are good practices for general hygiene and infant care, they are not specifically targeted at preventing rotavirus infection.
Question 2 of 5
A 70-year-old client is admitted to the hospital after 24 hours of acute diarrhea. To determine fluid status, which initial data is most important for the nurse to obtain?
Correct Answer: A
Rationale: The correct answer is A: Usual and current weight. Weight changes are the most direct indicator of fluid status in a patient with acute diarrhea. Monitoring weight loss or gain can provide crucial information about fluid balance. Option B, color and amount of urine, though important for assessing renal function, is not as direct an indicator of fluid status as weight. Option C, number and frequency of stools, is relevant for assessing the severity of diarrhea but does not provide direct information on fluid status. Option D, intake and output 24 hours prior to admission, does not reflect the current fluid status and may not be accurate in a rapidly changing condition like acute diarrhea.
Question 3 of 5
When deciding whether to join a nursing strike called after collective bargaining efforts have failed, which factor is most important for the nurse to consider?
Correct Answer: B
Rationale: The correct answer is B. The role of nurses as client advocates is crucial when considering the impact of a strike on patient care. Nurses have a responsibility to advocate for their patients' well-being at all times. Choices A, C, and D, although important, are not the most critical factor to consider in this situation. The Nurse Practice Act of the State is essential for guiding nursing practice, standards of clinical nursing practice ensure quality care, and personal values are important; however, the primary focus during a strike should be on the role of nurses as client advocates.
Question 4 of 5
A high school football player comes to the clinic complaining of severe acne. The mother reports recent behavior changes, including irritability and suspiciousness of friends. The nurse's assessment reveals an elevated blood pressure. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: In this scenario, the high school football player presenting with severe acne, behavior changes, elevated blood pressure, and suspicion of friends suggests the possible use of anabolic steroids. Anabolic steroid use can lead to such symptoms. Therefore, the nurse should first inquire about the possible use of anabolic steroids to address the root cause of the presenting issues. Encouraging the client to see a dermatologist (Choice A) may be necessary but addressing the underlying cause is crucial first. Referring the adolescent to a substance abuse program (Choice B) is premature without confirming steroid use. Suggesting a low-salt, low-fat, and caffeine-free diet (Choice C) is not the priority in this situation where a serious issue like anabolic steroid use needs immediate attention.
Question 5 of 5
Identify the placement of the stapes footplate into the bony labyrinth.
Correct Answer: A
Rationale: The correct answer is A: Fenestra vestibuli. The stapes footplate is placed into the fenestra vestibuli of the bony labyrinth. This structure is also known as the oval window and is located at the junction of the middle ear and inner ear. Choice B, Fenestra cochleae, is incorrect as this opening is also known as the round window and is located near the base of the cochlea. Choice C, Tympanic membrane, is incorrect as it is also known as the eardrum and separates the external ear from the middle ear. Choice D, Round window, is incorrect as it is the opening covered by the secondary tympanic membrane and is important for the dissipation of sound waves in the cochlea.
