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. The client is receiving heparin for thrombophlebitis of the left lower extremity. Which of the following drugs reverses the effects of heparin?

• A. Cyanocobalamin
• B. Protamine sulfate
• C. Streptokinase
• D. Sodium warfarin

Correct answer: B

Rationale: The correct answer is Protamine sulfate. Protamine sulfate is the antidote for heparin, as it reverses its effects. Cyanocobalamin is a form of Vitamin B12 and is not used to reverse heparin effects. Streptokinase is a thrombolytic agent that is used to dissolve blood clots, not to reverse heparin effects. Sodium warfarin is an anticoagulant, but it is not the antidote for heparin. Therefore, answers A, C, and D are incorrect as they do not reverse the effects of heparin.

3. The nurse is assessing the client recently returned from surgery. The nurse is aware that the best way to assess pain is to:

• A. Take the blood pressure, pulse, and temperature
• B. Ask the client to rate his pain on a scale of 0-5
• C. Watch the client's facial expression
• D. Ask the client if he is in pain

Correct answer: B

Rationale: The best way to evaluate pain levels is to ask the client to rate his pain on a scale. This method provides a more standardized and quantifiable measure of pain compared to subjective observations like facial expressions (choice C) or direct questioning (choice D). Monitoring vital signs (choice A) can be part of pain assessment but is not as specific or reliable as asking the client to self-report pain intensity.

4. A client reports that someone is in the room and trying to kill him. The nurse's best response is:

• A. "No one is in your room. Let's get you more medicine."?
• B. "I do not see anyone, but you seem to be very frightened."?
• C. "No one can hurt you here."?
• D. "Just tell the person to go away."?

Correct answer: B

Rationale: When a client reports hallucinations or delusions, it is crucial to respond in a non-confrontational and empathetic manner. Choice B acknowledges the client's fear without confirming the delusion, showing understanding, and providing reassurance. This response validates the client's feelings without reinforcing the false belief. The other responses in choices A, C, and D dismiss the client's feelings or perceptions, which can escalate the situation and harm the therapeutic relationship.

5. 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: Explanation: Ashley is displaying symptoms of severe anxiety, including confusion, trouble focusing, dizziness, nausea, rapid pulse, and hyperventilation. These somatic symptoms, along with changes in vital signs, indicate severe anxiety. In severe anxiety, individuals are unable to solve problems and have a poor grasp of their environment. On the other hand, mild anxiety may lead to mild discomfort or even enhanced performance, while moderate anxiety results in difficulty grasping information and minor changes in vital signs. Panic, the most severe level of anxiety, involves markedly disturbed behavior and a potential loss of touch with reality. Therefore, based on Ashley's symptoms, her anxiety level should be assessed as severe.
