CAT Exam Practice Test

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.

Correct Answer: B

Rationale: Encouraging the client to join a support group is the best option to address the client's psychosocial need for acceptance. Support groups provide a sense of belonging, understanding, and acceptance from peers who share similar experiences. This helps the client feel accepted despite their condition. Wearing gloves when providing care, shaking hands during an introduction, and allowing the client to express feelings openly are important but do not directly address the client's need for acceptance.

Correct Answer: A

Rationale: The correct answer is A: 'I am sorry, but your friend was killed in the accident.' In this situation, honesty and compassion are essential. The nurse should provide the client with truthful information, acknowledging the client's need to know the reality of the situation. Choice B is dismissive and does not address the client's inquiry directly. Choice C is a deflecting question and does not offer the direct information the client is seeking. Choice D provides false reassurance, which is not appropriate in this circumstance where the reality needs to be communicated.

Correct Answer: B

Rationale: The correct answer is B because older adults are at higher risk for delirium, especially following a recent suicide attempt, which can be a significant stressor. Choice A is less likely to develop delirium solely due to difficulty sleeping; delirium is more complex and multifactorial. Choice C, a young adult taking antipsychotic medications, may be at risk for other conditions but not necessarily delirium. Choice D, a middle-aged woman using supplemental oxygen, is not directly linked to an increased risk of delirium compared to the older client who recently attempted suicide.

Correct Answer: D

Rationale: The correct action for the charge nurse to implement is to notify the health care provider of the abnormal pulse rate and pulse volume. A weak pulse with bradycardia (pulse rate of 44 beats per minute) requires immediate follow-up to investigate potential underlying issues. In this situation, it is crucial to involve the healthcare provider for further assessment and intervention. Instructing the UAP to count the client's apical pulse rate for sixty seconds (Choice A) may delay necessary actions. Determining capillary refill time (Choice B) is not directly related to addressing a weak pulse, and assigning an LPN to assess an apical radial pulse deficit (Choice C) is not as urgent as involving the healthcare provider.
