CAT Exam Practice
1. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
- A. Ate an extra peanut butter sandwich before gym class
- B. Incorrectly drew up and administered too much insulin
- C. Was not hungry, so she skipped eating lunch
- D. Has had a cold and ear infection for the past two days
Correct answer: B
Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.
2. An adult male was diagnosed with stage IV lung cancer three weeks ago. His wife approaches the nurse and asks how she will know that her husband's death is imminent because their two adult children want to be there when he dies. What is the best response by the nurse?
- A. Explain that the client will start to lose consciousness and his body systems will slow down
- B. Reassure the spouse that the healthcare provider will let her know when to call the children
- C. Offer to discuss the client’s health status with each of the adult children
- D. Gather information on how long it will take for the children to arrive
Correct answer: A
Rationale: The best response for the nurse is to explain that the client will start to lose consciousness and his body systems will slow down. Providing information on the signs of impending death helps the family prepare emotionally and allows them to be present at the appropriate time. Choice B is incorrect because it does not empower the family with the knowledge they seek. Choice C is incorrect as discussing the client’s health status individually with the adult children may not address the wife's immediate concern. Choice D is incorrect as the priority should be on preparing the family for the signs of imminent death rather than focusing on logistical details.
3. A 37-year-old client diagnosed with chronic kidney disease (CKD) is being treated for renal osteodystrophy. Which nursing diagnosis is most likely to be included in this client’s plan of care?
- A. High risk for infection related to subclavian catheter
- B. High risk of injury related to ambulation
- C. Knowledge deficit related to a high-protein diet
- D. Hygiene self-care deficit related to uremic frost
Correct answer: D
Rationale: The correct answer is D. Uremic frost is a condition in which urea and other waste products are excreted through the skin, leaving a powdery residue. This indicates poor hygiene and self-care, common issues in patients with CKD and renal osteodystrophy. Proper hygiene measures are essential to prevent complications. Choices A, B, and C are less likely to be included in the plan of care for a CKD patient with renal osteodystrophy. Choice A is more related to a vascular access issue, choice B is more related to mobility concerns, and choice C is more related to dietary education.
4. A client in the intensive care unit is being mechanically ventilated, has an indwelling urinary catheter in place, and is exhibiting signs of restlessness. Which action should the nurse take first?
- A. Review the heart rhythm on cardiac monitors
- B. Check urinary catheter for obstruction
- C. Auscultate bilateral breath sounds
- D. Give PRN dose of lorazepam (Ativan)
Correct answer: B
Rationale: When a client in the intensive care unit is mechanically ventilated, has an indwelling urinary catheter, and is restless, the priority action is to check the urinary catheter for obstruction. Restlessness in this context could be due to a blocked catheter causing discomfort or urinary retention, which needs immediate attention to prevent complications. Reviewing the heart rhythm on cardiac monitors can be important but is not the priority in this scenario. Auscultating bilateral breath sounds is also important in a ventilated client but addressing the potential immediate issue of a blocked catheter takes precedence. Giving a PRN dose of lorazepam should not be the first action without addressing the underlying cause of restlessness.
5. A client is admitted for an exacerbation of heart failure (HF) and is being treated with diuretics for fluid volume excess. In planning nursing care, which interventions should the nurse include? (Select all that apply)
- A. Encourage oral fluid intake of 3,000 ml/day
- B. Observe for evidence of hypokalemia
- C. Teach the client how to restrict dietary sodium
- D. Monitor PTT, PT, and INR lab values
Correct answer: B
Rationale: The correct interventions to include when a client with heart failure is being treated with diuretics for fluid volume excess are to observe for evidence of hypokalemia. Diuretics can lead to potassium loss, resulting in hypokalemia. Monitoring for this electrolyte imbalance is crucial. Encouraging oral fluid intake of 3,000 ml/day may exacerbate fluid volume excess in a client with heart failure. Teaching the client how to restrict dietary sodium is important in managing heart failure, but it is not directly related to the use of diuretics for fluid volume excess. Monitoring PTT, PT, and INR lab values is not typically associated with diuretic therapy for heart failure but rather with anticoagulant therapy.
