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 successful resolution of the nursing diagnosis Negative Self-Concept (related to unrealistic self-expectations) is when the client can:

• A. report a positive self-concept.
• B. identify negative thoughts.
• C. recognize positive thoughts.
• D. give one positive cue with each negative cue

Correct answer: A

Rationale: The correct answer is to 'report a positive self-concept.' The problem statement is Negative Self-Concept, so the goal is for the client to achieve a positive self-concept. This involves helping the client recognize their worth and strengths. Choices B, C, and D do not directly address the resolution of Negative Self-Concept. Identifying negative thoughts (B) is a step towards improvement but does not represent a successful resolution. Recognizing positive thoughts (C) is positive but not the primary goal in addressing Negative Self-Concept. 'Give one positive cue with each negative cue' (D) is not as comprehensive as achieving an overall positive self-concept.

3. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect.
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence.
• C. addiction is the term used to describe physical dependence with withdrawal symptoms and tolerance.
• D. the client has a dual diagnosis of substance abuse and chronic back pain

Correct answer: A

Rationale: Drug tolerance is characterized by the ability to ingest a larger dose without adverse effects and decreased sensitivity to the substance. In this scenario, the client needing an increased dose of hydrocodone to achieve the same pain relief indicates tolerance developing, not addiction. Choice B is incorrect as it describes drug dependence, where the individual is preoccupied with the drug and has a loss of control. Choice C is incorrect because addiction involves psychological behaviors related to substance use, not just physical dependence with withdrawal symptoms and tolerance. Choice D is incorrect as it refers to a dual diagnosis, which is the coexistence of substance abuse and psychiatric disorders, not the development of tolerance to a drug.

4. What is a common characteristic of individuals who become batterers?

• A. Grew up in a loving, secure home.
• B. Was an only child.
• C. Was physically or psychologically abused.
• D. Admits they have a problem with anger.

Correct answer: C

Rationale: The correct answer is 'Was physically or psychologically abused.' Research indicates that many individuals who become batterers have a history of being abused themselves. This cycle of abuse can influence their behavior as adults. Choice A is incorrect because growing up in a loving home does not necessarily prevent someone from becoming a batterer. Choice B is incorrect as being an only child is not a determining factor in becoming a batterer. Choice D is incorrect because while admitting to anger issues is a positive step, it is not a common characteristic of individuals who become batterers.

5. A client asks the nurse if all donor blood products are cross-matched with the recipient to prevent a transfusion reaction. Which of the following always requires cross-matching?

• A. packed red blood cells
• B. platelets
• C. plasma
• D. granulocytes

Correct answer: A

Rationale: Corrected Rationale: Packed red blood cells contain antigens and antibodies that must be matched between the donor and recipient to prevent transfusion reactions. Platelets, plasma, and granulocytes do not contain red blood cells, so they do not require cross-matching. Platelets are matched based on ABO compatibility, while plasma and granulocytes are not routinely cross-matched as they lack red cell antigens.
