Nursing Elites

1. A nurse is caring for a client who has a new diagnosis of tuberculosis. Which of the following precautions should the nurse initiate to prevent transmission of the disease?

• A. Contact precautions
• B. Airborne precautions
• C. Droplet precautions
• D. Protective environment

Correct answer: B

Rationale: Tuberculosis is spread through small droplets measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client who has TB under airborne precautions to prevent the spread of microbes. Choice A, contact precautions, are used for diseases spread by direct or indirect contact. Choice C, droplet precautions, are for diseases spread by larger droplets. Choice D, protective environment, is used for immunocompromised clients to protect them from environmental pathogens.

2. A nurse is admitting a client who has suspected appendicitis. Which of the following findings should the nurse report to the provider immediately?

• A. Distended, board-like abdomen
• B. WBC count of 15,000/mm3
• C. Rebound tenderness over McBurney's point
• D. Temperature of 37.3°C (99.1°F)

Correct answer: A

Rationale: A distended, board-like abdomen should be reported to the provider immediately because it indicates peritonitis, a serious complication of appendicitis resulting from a ruptured appendix. Option B, an elevated WBC count, may indicate infection but is not as urgent as a board-like abdomen. Option C, rebound tenderness over McBurney's point, is a classic sign of appendicitis but does not indicate immediate life-threatening complications. Option D, a slightly elevated temperature, is not as concerning as a distended, board-like abdomen.

3. What should be done when continuous bubbling is observed in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Replace the chest tube system
• C. Clamp the chest tube
• D. Continue to monitor the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate action is to tighten the connections of the chest tube system. This may resolve an air leak that is causing the continuous bubbling. Option B, replacing the chest tube system, is not the initial step to take and is considered more invasive. Clamping the chest tube (option C) can lead to complications and should not be done unless instructed by a healthcare provider. Continuing to monitor the chest tube (option D) without taking any corrective action may delay necessary interventions.

4. What is a characteristic sign of hypokalemia on an ECG?

• A. Flattened T waves
• B. ST elevation
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

5. What is the priority nursing intervention for a patient admitted with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Obtain cardiac enzymes
• C. Get IV access
• D. Auscultate heart sounds

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This intervention is a priority for a patient with possible acute coronary syndrome because nitroglycerin helps vasodilate coronary arteries, increase blood flow to the heart muscle, relieve chest pain, and reduce cardiac workload. Obtaining cardiac enzymes (choice B) is important for diagnosing myocardial infarction but is not the initial priority. Getting IV access (choice C) is essential for medication administration and fluid resuscitation but is not the priority over administering nitroglycerin. Auscultating heart sounds (choice D) is a routine assessment but does not address the immediate need to relieve chest pain and improve blood flow to the heart in acute coronary syndrome.
