Nursing Elites

1. How can a diet high in fiber content benefit an individual?

• A. aid in rapid weight loss.
• B. reduce diabetic ketoacidosis.
• C. lower cholesterol.
• D. reduce the requirement for folate.

Correct answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.

2. A client is admitted to telemetry with a diagnosis of diabetes at 3pm. At 10pm, the client is unresponsive. BP is 98/64, Resp 38, HR 100, T 97. The nurse notes a fruity smell on the client's breath. The nurse recognizes that the client is in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: Based on the client's unresponsiveness, fruity breath smell, and the presence of diabetes, the nurse can infer that the client is experiencing diabetic ketoacidosis (DKA). DKA is a complication of diabetes characterized by the accumulation of ketones in the body, leading to metabolic acidosis. The fruity breath smell is due to the presence of ketones. Therefore, the correct acid-base imbalance in this scenario is metabolic acidosis. Choice A, respiratory acidosis, is incorrect because the scenario does not provide evidence of primary respiratory dysfunction. Choice B, respiratory alkalosis, is incorrect as the client's condition does not align with the typical causes and symptoms of respiratory alkalosis. Choice D, metabolic alkalosis, is incorrect as the symptoms and history provided do not suggest a state of metabolic alkalosis.

3. During the admission assessment for a client undergoing breast augmentation, which information should the nurse prioritize reporting to the surgeon before surgery?

• A. The client is concerned about who will care for her two children while she recovers.
• B. The client has a history of postoperative dehiscence after a previous C-section.
• C. The client's statement that her last menstrual period was 8 weeks prior.
• D. The client's concerns over pain control postoperatively.

Correct answer: C

Rationale: The most important information for the nurse to report to the surgeon before surgery is the client's statement that her last menstrual period was 8 weeks prior. This information is crucial as the client may be pregnant, and a pregnancy test will need to be completed before administering any anesthetic agents. Reporting this detail ensures patient safety and prevents potential risks associated with anesthesia. Choices A, B, and D are important aspects of care but do not take precedence over the need to rule out pregnancy before surgery.

4. Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?

• A. open leg fracture
• B. open head injury
• C. stab wound to the chest
• D. traumatic amputation of a thumb

Correct answer: C

Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.

5. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
