CAT Exam Practice Test

Correct Answer: A

Rationale: The most appropriate response by the nurse in this situation is to reassure the spouse that the client will be well cared for and provide information about the facility's care practices. This response not only addresses the spouse's concerns directly but also helps in building trust and confidence in the care provided. Choice B is not ideal as it may cause unnecessary worry about the fluctuating care levels. Choice C puts the responsibility on the spouse to monitor care, which may not always be feasible or appropriate. Choice D deflects the concern to other family members instead of addressing the spouse's worries directly.

Correct Answer: B

Rationale: An elevated creatinine level indicates possible renal impairment, which requires intervention. High creatinine levels are associated with decreased kidney function, and in this case, it suggests potential renal issues due to long-term corticosteroid therapy. Monitoring renal function is crucial in clients with osteoporosis on corticosteroid therapy to prevent further complications. Total calcium levels within the normal range are suitable for a client with osteoporosis receiving calcium carbonate. Phosphate and fasting glucose levels do not directly indicate renal impairment in this scenario.

Correct Answer: B

Rationale: To calculate the infusion rate, first, find the total dose required per hour, which is the patient's weight (220 pounds) multiplied by the prescribed rate (18 units/kg/hour). This equals 3960 units/hour. Next, determine how many ml of the solution contain 25,000 units; this is 250 ml. Divide the total dose required per hour (3960 units) by the units per ml (25,000 units/250 ml) to find how many ml are needed per hour. This results in 27 ml/hour. Therefore, the nurse should program the infusion pump to deliver 27 ml/hour. Choice A (18) is incorrect as it does not account for the concentration of the heparin solution. Choices C (36) and D (45) are incorrect as they do not reflect the accurate calculations based on the patient's weight and the heparin concentration in the solution.

Correct Answer: B

Rationale: The correct answer is B: 'Impaired skin integrity related to altered circulation and pressure.' This nursing diagnosis is the most appropriate as it directly addresses the Stage II pressure ulcer on the left hip, which is caused by altered circulation and pressure due to the client's left-side paralysis. Choice A is incorrect because it focuses on the risk for impaired tissue integrity rather than the current issue of impaired skin integrity. Choice C is incorrect as ineffective tissue perfusion is not the primary issue in this scenario. Choice D is incorrect as it only addresses the left-side paralysis and not the pressure ulcer or altered circulation.

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.
