ATI Pathophysiology Exam 2
1. A nurse working in a busy orthopedic clinic is asked to perform the Tinel sign on a client having problems in her hand/wrist. In order to test Tinel sign, the nurse should give the client which direction?
- A. Stand tall, arms at your side, shut your eyes; place the tip of your index finger to your nose.
- B. Hold your wrist in complete flexion, keep it in this position for 60 seconds. How does your hand feel after placing it in a neutral position?
- C. I'm going to tap (percuss) over the median nerve in your wrist; tell me what sensation you feel while I am doing this. Does the sensation stay in the wrist or go anywhere else?
- D. I'm going to tap this tuning fork; place it on the side of your thumb, then tell me what you are feeling in your hand and wrist.
Correct answer: C
Rationale: The correct answer is C. The Tinel sign involves percussing over the median nerve in the wrist to test for carpal tunnel syndrome. Choice A is incorrect as it describes a different action unrelated to the Tinel sign. Choice B is also incorrect as it involves holding the wrist in flexion, which is not part of the Tinel sign assessment. Choice D is incorrect as it mentions using a tuning fork on the thumb, which is not the correct technique for assessing the Tinel sign.
2. A patient taking an oral contraceptive missed one pill. What should the nurse teach the patient to do?
- A. Take two pills as soon as you remember, then continue the regular schedule.
- B. Take one pill as soon as you remember, then continue the regular schedule.
- C. Skip the missed pill and continue the regular schedule.
- D. Take two pills immediately, then continue the regular schedule.
Correct answer: A
Rationale: When a patient taking an oral contraceptive misses one pill, the correct action is to take two pills as soon as they remember and then continue the regular schedule. Option A is the correct answer because doubling up the dose helps maintain the effectiveness of the contraceptive. Option B is incorrect because taking only one pill after missing one may decrease contraceptive effectiveness. Option C is wrong as skipping the missed pill can also reduce effectiveness. Option D is inaccurate because taking two pills immediately is not necessary; the patient should take the missed pill as soon as remembered and then resume the regular dosing schedule.
3. What is the best method to identify which type of stroke the client has?
- A. Obtain a 12-lead electrocardiogram STAT
- B. Obtain a blood specimen for electrolytes and blood cultures
- C. Ask the client about current allergies
- D. Obtain a cranial computerized tomogram (CT) STAT
Correct answer: D
Rationale: The correct answer is to obtain a cranial computerized tomogram (CT) STAT. A cranial CT scan is the best method to quickly identify the type of stroke a client is experiencing. Options A, B, and C are not appropriate for identifying the type of stroke as they are not specific to assessing stroke types.
4. Which of the following are normal arterial blood gas values?
- A. PH 7.25, PaCO2 52 mm Hg, PaO2 75 mm Hg, HCO3 18 mEq/L
- B. PH 7.50, PaCO2 30 mm Hg, PaO2 80 mm Hg, HCO3 28 mEq/L
- C. PH 7.40, PaCO2 40 mm Hg, PaO2 90 mm Hg, HCO3 24 mEq/L
- D. PH 7.15, PaCO2 30 mm Hg, PaO2 50 mm Hg, HCO3 24 mEq/L
Correct answer: C
Rationale: The correct answer is C: PH 7.40, PaCO2 40 mm Hg, PaO2 90 mm Hg, HCO3 24 mEq/L. These values represent a balanced state for arterial blood gas. Choice A has lower than normal PH and HCO3 levels and higher PaCO2 and lower PaO2 levels. Choice B has higher than normal PH and HCO3 levels, lower PaCO2, and a normal PaO2 level. Choice D has a significantly lower PH and PaO2 level, normal HCO3 level, and low PaCO2 level, indicating an acidic state with impaired oxygenation.
5. A patient is diagnosed with type 2 diabetes mellitus. Which of the following is a common initial treatment strategy?
- A. Insulin therapy
- B. Lifestyle modification and metformin
- C. Sulfonylureas
- D. Thiazolidinediones
Correct answer: B
Rationale: The correct answer is B: Lifestyle modification and metformin. When managing type 2 diabetes mellitus, initial treatment often involves lifestyle changes such as adopting a healthy diet and increasing physical activity, along with the oral medication metformin. Insulin therapy (choice A) is usually reserved for cases where lifestyle changes and oral medications are not sufficient to control blood sugar levels. Sulfonylureas (choice C) and thiazolidinediones (choice D) are also oral medications used in diabetes management, but they are not typically recommended as first-line treatments due to various side effects and considerations in type 2 diabetes management.
