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. When the nurse who was not promoted first read the memo and learned that the other nurse had received the promotion, she left the room in tears. This behavior is an example of:

• A. conversion.
• B. regression
• C. introjection.
• D. rationalization

Correct answer: B

Rationale: Crying is a regressive behavior. The ego returned to an earlier, comforting, and less-mature way of behaving in the face of disappointment. Regression involves reverting to an earlier stage of development to cope with stress or conflict. In this scenario, the nurse regressed to a childlike state by crying when faced with the disappointment of not getting the promotion, demonstrating regression as a defense mechanism. Conversion involves transforming anxiety into a physical symptom. Introjection involves unconsciously identifying intensely with another person. Rationalization involves unconsciously creating acceptable explanations to justify unacceptable ideas, actions, or feelings. Therefore, the correct answer is regression as it aligns with the nurse's behavior of regressing to a childlike state by crying due to the disappointment of not receiving the promotion.

3. The nurse is preparing a client for mammography. To prepare the client for a mammogram, the nurse should tell the client:

• A. To omit creams, powders, or deodorants before the exam
• B. To restrict fat intake for 1 week before the test
• C. That mammography replaces the need for self-breast exams
• D. That mammography requires a higher dose of radiation than an x-ray

Correct answer: A

Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.

4. A client is admitted with a diagnosis of Multiple Drug Use. The nurse should plan care based on knowledge that

• A. Multiple drug use is common.
• B. People might use more than one drug to enhance the effect or relieve withdrawal symptoms.
• C. Combining alcohol and barbiturates can be dangerous due to their combined depressant effects.
• D. Assessment and intervention are more complex with multiple drug use due to the synergistic effects.

Correct answer: B

Rationale: When caring for a client with Multiple Drug Use, it is important to understand that individuals may use more than one drug simultaneously or sequentially to enhance the effect of a particular drug or to relieve withdrawal symptoms. This practice is common among substance users. For example, heroin users may also consume alcohol, marijuana, or benzodiazepines. Combining drugs can have various effects, such as intensifying intoxication or alleviating withdrawal symptoms. It is crucial to recognize that multiple drug use can complicate assessment and intervention due to the diverse effects of different substances on the client's health. Option A is incorrect as multiple drug use is indeed common, not uncommon. Option C is incorrect because combining alcohol and barbiturates can be dangerous due to their combined depressant effects. Option D is incorrect because multiple drug use complicates assessment and intervention rather than making them easier, as the effects of different drugs on the client need to be carefully considered.

5. Incidences of child abuse appear to be higher in the African-American community and might be explained by:

• A. the increased number of single-parent households in African-American communities
• B. more single-parent households in African-American communities
• C. stricter child-rearing practices in African-American households
• D. a higher occurrence of rage in African Americans

Correct answer: B

Rationale: Child abuse is often associated with lower socioeconomic status and single-parent households due to increased stress and fewer support systems. Choice A is correct as single-parent households can face more challenges leading to a higher risk of child abuse. Choice B is the correct answer as it aligns with the risk factors associated with child abuse. Choice C is incorrect because there is no direct correlation between stricter child-rearing practices and child abuse rates. Choice D is incorrect because attributing child abuse to a higher occurrence of rage in African Americans is a stereotype and lacks evidence.
