CAT Exam Practice Test

Correct Answer: A

Rationale: The Gower sign is a characteristic finding in Duchenne muscular dystrophy where a child uses hands to walk up the legs when standing from a sitting position due to proximal muscle weakness. This behavior is indicative of the child trying to compensate for weak hip and thigh muscles. Choices B, C, and D are incorrect because they do not describe the specific behavior associated with the Gower sign. Muscular atrophy, contractures of both hips, and an unsteady gait with foot slapping are not directly related to the Gower sign.

Correct Answer: A

Rationale: The correct answer is A. Bedfast clients with increased serum BUN and creatinine levels are at high risk for overflow incontinence. This occurs due to decreased bladder function and reduced ability to sense bladder fullness, leading to the bladder overfilling and leaking urine. Choice B describes symptoms related to possible urinary tract infections or renal issues, but these do not directly indicate overflow incontinence. Choice C, a history of frequent urinary tract infections, may suggest other urinary issues but not specifically overflow incontinence. Choice D, a confused client who forgets to go to the bathroom, is more indicative of functional incontinence rather than overflow incontinence.

Correct Answer: D

Rationale: Correct Answer: The best response for the nurse is to choose option D, 'I understand you are frustrated with the wait time.' This response demonstrates empathy and validates the client's feelings, helping to defuse the situation. Choice A is not the best response as it does not directly address the client's emotions or concerns. Choice B is inappropriate as it gives preferential treatment based on the client's behavior. Choice C, while true, does not acknowledge the client's frustration or offer empathy.

Correct Answer: C

Rationale: Corrected Rationale: Decreased skin turgor is a classic sign of dehydration. When someone is dehydrated, the skin loses its elasticity and becomes less turgid. This change is easily assessed by gently pinching and pulling up the skin on the back of the hand or forearm. If the skin remains elevated or tents rather than quickly returning to its normal position, it indicates dehydration. Moist mucous membranes (Choice A) are actually a sign of adequate hydration. Increased urine output (Choice B) can be a sign of dehydration, but decreased skin turgor is a more specific indicator. Elevated blood pressure (Choice D) is not typically associated with fluid volume deficit and may indicate other health issues.

Correct Answer: A

Rationale: The correct answer is A: Topical corticosteroid. Topical corticosteroids are commonly used to manage itching in eczema by reducing inflammation and suppressing the immune response. In this case, for severe pruritus in eczema, a topical corticosteroid would be appropriate. Choice B, Topical scabicide, is used to treat scabies, not eczema. Choice C, Topical alcohol rub, is not typically used to manage pruritus in eczema. Choice D, Transdermal analgesic, is more for pain relief and not specifically targeted at managing itching associated with eczema.
