ATI Capstone Medical Surgical Assessment 2 Quizlet
1. What teaching should be provided after cataract surgery?
- A. Avoid NSAIDs
- B. Wear dark glasses outdoors
- C. Creamy white drainage is normal
- D. Avoid bright lights
Correct answer: A
Rationale: The correct teaching that should be provided after cataract surgery is to avoid NSAIDs. NSAIDs should be avoided to prevent bleeding, especially in the eye area. While wearing dark glasses outdoors is important to protect the eyes, it is not the most critical teaching after cataract surgery. Creamy white drainage being normal is not relevant to post-cataract surgery teaching. Avoiding bright lights is generally recommended for patients with certain eye conditions but is not a specific teaching point after cataract surgery.
2. What lab value should be prioritized for a patient with HIV?
- A. CD4 T-cell count below 180 cells/mm3
- B. Serum albumin levels
- C. White blood cell count
- D. Hemoglobin levels
Correct answer: A
Rationale: A CD4 T-cell count below 180 cells/mm3 should be prioritized for a patient with HIV. This value is crucial as it indicates severe immunocompromise in HIV-infected individuals. Monitoring CD4 T-cell count helps assess the status of the immune system and guides treatment decisions. Serum albumin levels (choice B) may reflect the patient's nutritional status and overall health but are not as specific to HIV disease progression. White blood cell count (choice C) and hemoglobin levels (choice D) can be affected by various factors and are not as directly linked to HIV management as the CD4 T-cell count in this context.
3. A client is being taught about fecal occult blood testing (FOBT) for colorectal cancer screening. Which of the following statements should the nurse include in the teaching?
- A. Your provider will use a stool sample obtained during a digital rectal examination to perform the test.
- B. Your provider will recommend a stimulant laxative before the test to empty the bowel.
- C. You should start annual fecal occult blood testing for colorectal cancer screening at the age of 40.
- D. You should avoid corticosteroids before the test.
Correct answer: D
Rationale: The correct answer is D because the nurse should advise the client to avoid corticosteroids, anti-inflammatory medications, and vitamin C before fecal occult blood testing to prevent false-positive results. Choice A is incorrect as stool samples for FOBT are usually collected using a kit at home. Choice B is incorrect because stimulant laxatives are not typically used before FOBT. Choice C is incorrect as guidelines recommend starting colorectal cancer screening at the age of 50, not 40.
4. What are the expected ECG changes in hypokalemia?
- A. Flattened T waves
- B. ST elevation
- C. Wide QRS complex
- D. Tall T waves
Correct answer: A
Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.
5. What intervention is needed for a patient with a chest tube and an air leak?
- A. Tighten the connections of the chest tube system
- B. Replace the chest tube
- C. Clamp the chest tube
- D. Continue to monitor the chest tube
Correct answer: A
Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.
