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 woman asks, "How much alcohol can I safely drink while pregnant?"? The nurse's best response is:

• A. "The amount of alcohol that is safe during pregnancy is unknown."?
• B. "Consuming one or two beers or glasses of wine a day is considered safe for a healthy pregnant woman."?
• C. "Drinking three or more drinks on any given occasion is the only harmful type of drinking during pregnancy."?
• D. "You can have a drink to help you relax and get to sleep at night."?

Correct answer: A

Rationale: The correct answer is, "The amount of alcohol that is safe during pregnancy is unknown."? It is crucial for pregnant women to avoid alcohol as there is no known safe amount during pregnancy. Consuming any amount of alcohol can harm the developing fetus and increase the risk of fetal alcohol syndrome, a condition characterized by mental and physical abnormalities in infants. Choices B, C, and D are incorrect because they provide misleading information that can potentially harm the fetus. Pregnant women should abstain from alcohol to ensure the health and well-being of their baby.

3. 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.

4. The nurse is caring for a client who is dying. While assessing the client for signs of impending death, the nurse observes the client for:

• A. elevated blood pressure.
• B. Cheyne-Stokes respiration.
• C. elevated pulse rate.
• D. decreased temperature.

Correct answer: B

Rationale: Cheyne-Stokes respirations are a pattern of breathing characterized by rhythmic waxing and waning of respirations from very deep to very shallow breathing with periods of temporary apnea. This pattern is often associated with conditions like cardiac failure and can be a sign of impending death. Elevated blood pressure and pulse rate are not typically associated with the dying process. Decreased temperature is also not a common sign of impending death. Therefore, option B, Cheyne-Stokes respiration, is the correct choice when assessing a client for signs of impending death.

5. When working with a client diagnosed with Borderline Personality Disorder who frequently attempts self-harm, what is the best intervention to facilitate behavior change?

• A. Constantly observing the client to prevent self-harm.
• B. Enlisting the client in defining and describing harmful behaviors.
• C. Checking on the client every 15 minutes to ensure they are not engaging in harmful behavior.
• D. Removing all items from the environment that the client could use to harm themselves.

Correct answer: B

Rationale: The most effective intervention when working with clients who have a history of self-harm, like the client diagnosed with Borderline Personality Disorder, is to involve them actively in their treatment. By enlisting the client to define and describe the harmful behaviors, the client becomes an integral part of identifying triggers and understanding the underlying causes of their actions. This approach empowers the client, promotes self-awareness, and fosters a sense of control over their behaviors. Constantly observing the client (Choice A) may lead to a lack of trust and hinder the therapeutic relationship. Checking on the client every 15 minutes (Choice C) may disrupt the client's sense of autonomy and privacy. Removing all items from the environment that could be used for self-harm (Choice D) is a temporary solution and does not address the root causes of the behavior.
