1. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

2. James returns home from school angry and upset because his teacher gave him a low grade on an assignment. After returning home from school, he kicks the dog. This coping mechanism is known as:

• A. denial
• B. suppression
• C. displacement
• D. fantasy

Correct answer: C

Rationale: The correct answer is 'displacement.' Displacement is a defense mechanism where emotions or impulses are transferred from their original source to a substitute target. In this scenario, James is displacing his anger from his teacher onto the dog. Choice A, 'denial,' involves refusing to acknowledge an unpleasant reality. Choice B, 'suppression,' is the conscious effort to push unwanted thoughts out of awareness. Choice D, 'fantasy,' refers to imagining scenarios that fulfill one's desires but are not based in reality.

3. The child with seizure disorder is being treated with Dilantin (phenytoin). Which of the following statements by the patient's mother indicates to the nurse that the patient is experiencing a side effect of Dilantin therapy?

• A. "She is very irritable lately."?
• B. "She sleeps quite a bit of the time."?
• C. "Her gums look too big for her teeth."?
• D. "She has gained about 10 pounds in the last 6 months."?

Correct answer: C

Rationale: The correct answer is '"Her gums look too big for her teeth."?' Hyperplasia of the gums is a known side effect associated with Dilantin therapy. Option A, '"She is very irritable lately,"?' is not a typical side effect of Dilantin. Option B, '"She sleeps quite a bit of the time,"?' is a common side effect of Dilantin but not specific to gum hyperplasia. Option D, '"She has gained about 10 pounds in the last 6 months,"?' is not typically associated with Dilantin therapy and is unrelated to the question.

4. Which task should not be performed by the licensed practical nurse?

• A. Inserting a Foley catheter
• B. Discontinuing a nasogastric tube
• C. Obtaining a sputum specimen
• D. Initiating a blood transfusion

Correct answer: D

Rationale: A licensed practical nurse should not initiate a blood transfusion. LPNs can assist with transfusions and verify ID numbers but should not be assigned to initiate the procedure. Inserting Foley catheters, discontinuing nasogastric tubes, and obtaining sputum specimens are within the scope of practice for LPNs. Therefore, options A, B, and C are tasks that LPNs can perform, making them incorrect choices.

5. A home health nurse is making preparations for morning visits. Which one of the following clients should the nurse visit first?

• A. A client with brain attack (stroke) receiving tube feedings
• B. A client with congestive heart failure complaining of nighttime dyspnea
• C. A client who had a thoracotomy 6 months ago
• D. A client with Parkinson’s disease

Correct answer: B

Rationale: The correct answer is B. The client with congestive heart failure complaining of nighttime dyspnea should be seen first as airway management is a priority in nursing care. This client's symptoms indicate potential respiratory distress, requiring immediate attention. Choices A, C, and D involve clients who are more stable and do not present with urgent or acute conditions that require immediate intervention. Choice A with a client receiving tube feedings for a stroke may require attention, but the urgency of addressing potential respiratory distress in choice B takes precedence. Choice C, a client who had a thoracotomy 6 months ago, unless presenting with acute distress, does not necessitate immediate attention. Choice D, a client with Parkinson's disease, is usually a chronic condition that does not typically require immediate intervention for the described scenario.
