CAT Exam Practice Test

Correct Answer: B

Rationale: The correct intervention is to infuse an additional bolus of normal saline. The client's presentation with a heart rate of 120 beats/minute, hypotensive blood pressure of 90/50 mmHg, and low CVP of 4 mm H2O indicates hypovolemic shock. Administering more normal saline can help in restoring intravascular volume and improving perfusion. Increasing the rate of normal saline infusion (Choice A) is not the best choice as it may lead to fluid overload. Lowering the head of the bed to a recumbent position (Choice C) could worsen hypotension by reducing venous return. Bringing a tracheostomy tray to the bedside (Choice D) is not a priority at this time as the client is already intubated, and the immediate concern is addressing the hypovolemia.

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.

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: 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: C

Rationale: The correct answer is C. Increasing fluid intake is essential for managing constipation. Adequate hydration helps soften stool and promotes bowel movements. Choices A and B are incorrect as decreasing laxative use without medical advice and suggesting specific foods like oatmeal with stewed prunes may not be suitable for every individual with constipation. Choice D is also incorrect as while seeking help with meal preparation can indirectly aid in managing constipation, the immediate need is to increase fluid intake.
