Nursing Elites

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. During a well-baby check of a 6-month-old infant, the nurse notes abrasions and petechiae of the palate. The nurse should:

• A. inquire about the possibility of sexual abuse.
• B. ask about the types of foods the child is eating.
• C. request to see the type of bottle used for feedings.
• D. question the parent about objects the child plays with.

Correct answer: A

Rationale: The correct answer is to inquire about the possibility of sexual abuse. Injuries to the soft palate such as bruising, abrasions, and petechiae can be signs of sexual abuse in infants. While oral sex may not leave significant physical evidence, these findings should raise suspicion. Option A is correct as it focuses on addressing potential abuse. Options B, C, and D are incorrect because the child's diet, the type of bottle used for feedings, and play objects are not likely related to the observed injuries. The presence of oral injuries suggests considering sexual abuse rather than other factors.

3. A home health nurse is making preparations for morning visits. Which one of the following clients should the nurse visit first?

• A. A client with brain attack (stroke) receiving tube feedings
• B. A client with congestive heart failure complaining of nighttime dyspnea
• C. A client who had a thoracotomy 6 months ago
• D. A client with Parkinson’s disease

Correct answer: B

Rationale: The correct answer is B. The client with congestive heart failure complaining of nighttime dyspnea should be seen first as airway management is a priority in nursing care. This client's symptoms indicate potential respiratory distress, requiring immediate attention. Choices A, C, and D involve clients who are more stable and do not present with urgent or acute conditions that require immediate intervention. Choice A with a client receiving tube feedings for a stroke may require attention, but the urgency of addressing potential respiratory distress in choice B takes precedence. Choice C, a client who had a thoracotomy 6 months ago, unless presenting with acute distress, does not necessitate immediate attention. Choice D, a client with Parkinson's disease, is usually a chronic condition that does not typically require immediate intervention for the described scenario.

4. A 25-year-old male is brought to the emergency room with a piece of metal in his eye. Which action by the nurse is correct?

• A. Use a magnet to remove the object.
• B. Rinse the eye thoroughly with saline.
• C. Cover both eyes with paper cups.
• D. Administer eye drops immediately.

Correct answer: C

Rationale: Covering both eyes with paper cups is the correct action as it helps prevent consensual movement of the affected eye. Attempting to remove the object with a magnet might cause trauma, making choice A incorrect. While rinsing the eye with saline may be necessary, it should be ordered by a doctor and is not the initial action for the nurse, making choice B incorrect. Administering eye drops immediately, as in choice D, is not appropriate in this scenario and does not address the primary concern of preventing further damage by limiting eye movement.

5. A 6-month-old client is admitted with possible intussusception. Which question during the nursing history is least helpful in obtaining information regarding this diagnosis?

• A. "Tell me about his pain."?
• B. "What does his vomit look like?"?
• C. "Describe his usual diet."?
• D. "Have you noticed changes in his abdominal size?"?

Correct answer: C

Rationale: The least helpful question in obtaining information regarding intussusception is "Describe his usual diet."? This question is least relevant to the specific symptoms and presentation of intussusception. Choices A, B, and D are more directly related to symptoms commonly associated with intussusception and can provide important diagnostic clues. Asking about pain, vomit appearance, and changes in abdominal size can help in assessing the severity and progression of the condition, making them more crucial questions to ask in this scenario. Pain is a cardinal symptom of intussusception, changes in vomit appearance may indicate gastrointestinal issues, and alterations in abdominal size can signify the presence of a mass or obstruction, all of which are pertinent in diagnosing and managing intussusception.
