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. Who may legally give informed consent?

• A. an 86-year-old male with advanced Alzheimer's disease
• B. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• C. a 14-year-old girl needing an appendectomy who is not an emancipated minor
• D. a 6-month-old baby needing bowel surgery

Correct answer: C

Rationale: The correct answer is a 14-year-old girl needing an appendectomy who is not an emancipated minor. Informed consent can be given by individuals who are competent and not minors. Minors are generally unable to provide informed consent unless they are emancipated. Choice A is incorrect because an 86-year-old male with advanced Alzheimer's disease is considered incompetent to make decisions. Choice D is incorrect because a 6-month-old baby is unable to provide consent. Emancipated minors are an exception to the minor rule, as they can provide consent for their own treatment.

3. The client is admitted to the unit after a cholecystectomy. Montgomery straps are utilized with this client. The nurse is aware that Montgomery straps are utilized on this client because:

• A. The client is at risk for evisceration.
• B. The client will require frequent dressing changes.
• C. The straps provide support for drains that are inserted in the incision.
• D. No sutures or clips are used to secure the incision.

Correct answer: B

Rationale: Montgomery straps are used to secure dressings that require frequent changes due to the large amount of drainage usually present after a cholecystectomy. They are also beneficial for clients allergic to various types of tape. Answer A is incorrect as the client is not at higher risk of evisceration. Answer C is incorrect because Montgomery straps are not used to support drains. Answer D is incorrect as sutures or clips are typically used to secure the incision after gallbladder surgery, not Montgomery straps.

4. The nurse is caring for a client with laryngeal cancer. Which finding ascertained in the health history would not be common for this diagnosis?

• A. Foul breath
• B. Dysphagia
• C. Diarrhea
• D. Chronic hiccups

Correct answer: C

Rationale: Diarrhea is not a common finding in clients with laryngeal cancer. Foul breath (A), dysphagia (B), and chronic hiccups (D) are expected findings associated with laryngeal cancer. Foul breath can result from tissue breakdown in the mouth and throat. Dysphagia, or difficulty swallowing, can occur due to the tumor's location affecting the swallowing mechanism. Chronic hiccups can be a symptom of irritation to the phrenic nerves from the cancer.

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.
