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. A healthcare provider is preparing to assess the acoustic nerve during a neurological examination. To assess this nerve, the provider uses which technique?

• A. Uses a tuning fork
• B. Asks the client to puff out the cheeks
• C. Tests taste perception on the client's tongue
• D. Checks the client's ability to clench the teeth

Correct answer: A

Rationale: Testing of cranial nerve VIII (acoustic nerve) involves assessing hearing acuity through techniques like the whispered voice test and tuning fork tests (Weber and Rinne). Using a tuning fork helps determine if sound lateralizes to one ear (Weber) and compares air conduction to bone conduction (Rinne). Asking the client to puff out the cheeks is for cranial nerve VII (facial nerve) function evaluation. Testing taste perception on the tongue assesses cranial nerve IX (glossopharyngeal nerve) function. Checking the ability to clench teeth assesses cranial nerve V (trigeminal nerve) motor function.

3. Tricyclics (Antidepressants) can sometimes have which of the following adverse effects on patients diagnosed with depression?

• A. Shortness of breath
• B. Fainting
• C. Large intestine ulcers
• D. Distal muscular weakness

Correct answer: B

Rationale: The correct answer is 'Fainting.' Tricyclic antidepressants can cause fainting and hypotension as adverse effects. Shortness of breath (Choice A) is not a common side effect of tricyclics. Large intestine ulcers (Choice C) are not typically associated with tricyclic antidepressants. Distal muscular weakness (Choice D) is not a common adverse effect of tricyclics but is commonly associated with other medications.

4. Ashley and her boyfriend Chris, both 19 years old, are transported to the Emergency Department after being involved in a motorcycle accident. Chris is badly hurt, but Ashley has no apparent injuries, though she appears confused and has trouble focusing on what is going on around her. She complains of dizziness and nausea. Her pulse is rapid, and she is hyperventilating. The nurse should assess Ashley's level of anxiety as:

• A. mild.
• B. moderate.
• C. severe.
• D. panic.

Correct answer: C

Rationale: Based on the symptoms described, Ashley's level of anxiety should be assessed as severe. In severe anxiety, individuals have difficulty solving problems and understanding their environment. They often exhibit somatic symptoms like dizziness, nausea, rapid pulse, and hyperventilation. In contrast, mild anxiety may lead to mild discomfort or even enhanced performance. Moderate anxiety involves grasping less information, mild difficulty in problem-solving, and slight changes in vital signs. Panic, on the other hand, is characterized by markedly disturbed behavior and a potential loss of touch with reality. Therefore, in Ashley's case, the presence of somatic symptoms and vital sign changes indicates severe anxiety.

5. A 25-year-old male is brought to the emergency room with a piece of metal in his eye. Which action by the nurse is correct?

• A. Use a magnet to remove the object.
• B. Rinse the eye thoroughly with saline.
• C. Cover both eyes with paper cups.
• D. Administer eye drops immediately.

Correct answer: C

Rationale: Covering both eyes with paper cups is the correct action as it helps prevent consensual movement of the affected eye. Attempting to remove the object with a magnet might cause trauma, making choice A incorrect. While rinsing the eye with saline may be necessary, it should be ordered by a doctor and is not the initial action for the nurse, making choice B incorrect. Administering eye drops immediately, as in choice D, is not appropriate in this scenario and does not address the primary concern of preventing further damage by limiting eye movement.
