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: AST

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. In a brief treatment program, what is a realistic short-term goal for a client who was raped?

• A. Identify all psychosocial problems
• B. Eliminate the client’s enticing behaviors
• C. Resolve feelings of trauma and fear
• D. Verbalize feelings about the event

Correct answer: D: Verbalize feelings about the event

Rationale: A realistic short-term goal for a client who was raped and is receiving a brief treatment program is for the client to verbalize feelings about the event. This goal focuses on helping the client express their emotions, which can be a crucial step in the healing process. Options A and C are incorrect because a brief treatment program is not typically aimed at identifying or resolving all psychosocial problems or deep-rooted trauma and fear. Option B is also incorrect as the goal is to support the client in processing their feelings rather than focusing on behaviors.

3. A client with cancer is admitted to the oncology unit. Stat lab values reveal Hgb 12.6, WBC 6500, K+ 1.9, uric acid 7.0, Na+ 136, and platelets 178,000. The nurse evaluates that the client is experiencing which of the following?

• A. Hypernatremia
• B. Hypokalemia
• C. Myelosuppression
• D. Leukocytosis

Correct answer: Hypokalemia

Rationale: The correct answer is 'Hypokalemia.' The potassium level of 1.9 indicates low potassium levels, a condition known as hypokalemia. The other lab values are within normal ranges: Hgb 12.6, WBC 6500, uric acid 7.0, Na+ 136, and platelets 178,000. Hypernatremia (choice A) refers to high sodium levels, which are not present in this case. Myelosuppression (choice C) is a decrease in bone marrow activity, which is not indicated by the lab values provided. Leukocytosis (choice D) is an increase in white blood cells, which is also not present based on the given values.

4. A 57-year-old woman is recently widowed. She states, “I will never be able to learn how to manage the finances. My husband did all of that.” Select the nurse’s response that could help raise the client’s self-esteem.

• A. “You feel inadequate because you have never learned to balance a checkbook.”
• B. “You should have insisted your husband teach you about the finances.”
• C. “You are strong and will learn how to manage your finances after a while.”
• D. “I believe in your strength to learn how to manage your finances in time.”

Correct answer: “You are strong and will learn how to manage your finances after a while.”

Rationale: The nurse should aim to boost the client's self-esteem by providing positive reinforcement. By stating, “You are strong and will learn how to manage your finances after a while,” the nurse acknowledges the client's strength and capability, encouraging her to believe in herself. Choice A is incorrect as it focuses on the client's inadequacy rather than empowering her. Choice B places unnecessary blame on the client for not taking action in the past. Choice D, though positive, slightly alters the nurse's original phrase, making choice C the most appropriate response to uplift the client's self-esteem.

5. The LPN is teaching a first-time mother about breastfeeding her newborn. Which statement, if made by the mother, would reflect that the teaching had been successful?

• A. “My baby should be having at least 4-6 wet diapers a day until 1 month.”
• B. “It’s nice that breastfed babies eat a bit less than formula-fed babies.”
• C. “My baby should be nursing 8-12 times a day during this period.”
• D. “I’m a little nervous about my milk coming in tomorrow. I’ve heard it’s uncomfortable.”

Correct answer: “My baby should be nursing 8-12 times a day during this period.”

Rationale: The correct answer is, '“My baby should be nursing 8-12 times a day during this period.”' This statement indicates successful teaching because newborns should nurse 8-12 times during the newborn period to ensure they receive adequate nutrition and establish a good milk supply. This frequency helps in meeting the baby's demands for growth and development. Choice A is incorrect because while it mentions the appropriate number of wet diapers a day once the mother's milk comes in, it does not reflect successful teaching about breastfeeding frequency. Choice B is incorrect because it discusses feeding amounts in comparison to formula-fed babies, which is not a direct indicator of successful breastfeeding teaching. Choice D is incorrect because it focuses on the mother's concerns about milk coming in, not on understanding the feeding frequency needed for the newborn.
