1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

2. A nurse is caring for a client who has a new temporary synchronous pacemaker. Which of the following should the nurse report to the provider?

• A. The client's pulse oximetry level is 96%.
• B. The client develops hiccups.
• C. The ECG shows pacing spikes after the QRS complex.
• D. The client's heart rate is 90 beats per minute.

Correct answer: C

Rationale: The correct answer is C. Pacing spikes after the QRS complex indicate a malfunction of the pacemaker and should be reported. Choice A is not directly related to the pacemaker function. Choice B, hiccups, are common and not typically associated with pacemaker issues. Choice D, a heart rate of 90 beats per minute, is within the normal range and does not indicate a pacemaker malfunction.

3. A healthcare professional is providing discharge teaching for a client with type 2 diabetes mellitus. Which resource should be provided?

• A. Personal blogs about managing the adverse effects of diabetes medications.
• B. Food label recommendations from the Institute of Medicine.
• C. Diabetes medication information from the Physicians' Desk Reference.
• D. Food exchange lists for meal planning from the American Diabetes Association.

Correct answer: D

Rationale: Food exchange lists from the American Diabetes Association are a valuable resource for meal planning in diabetes. These lists provide guidelines for portion control and help individuals make healthier food choices. Personal blogs may not always provide accurate and evidence-based information. Food label recommendations are important but may not specifically address meal planning for diabetes. Diabetes medication information is essential but not the primary focus when educating about dietary management for type 2 diabetes.

4. A client is being assessed in the PACU. Which of the following findings indicates decreased cardiac output?

• A. Shivering
• B. Oliguria
• C. Bradypnea
• D. Constricted pupils

Correct answer: B

Rationale: Oliguria is a sign of decreased cardiac output. Decreased cardiac output can lead to poor renal perfusion, resulting in decreased urine output (oliguria). This requires immediate intervention to improve cardiac function and perfusion. Shivering (Choice A) is a response to cold stress and does not directly indicate decreased cardiac output. Bradypnea (Choice C) refers to abnormally slow breathing rate and is more indicative of respiratory issues rather than decreased cardiac output. Constricted pupils (Choice D) are associated with the parasympathetic nervous system response and not directly related to cardiac output.

5. A nurse is preparing to perform a sterile dressing change. Which of the following actions should the nurse take when setting up the sterile field?

• A. Place the cap from the solution sterile side up on a clean surface.
• B. Open the outermost flap of the sterile kit away from the body.
• C. Place the sterile dressing within 1.25 cm of the edge of the sterile field.
• D. Set up the sterile field 5 cm below waist level.

Correct answer: B

Rationale: When setting up a sterile field for a dressing change, the nurse should open the outermost flap of the sterile kit away from the body. This action helps maintain the sterility of the field by minimizing the risk of contamination. Option A is incorrect because the cap from the solution should be placed sterile side down to prevent contamination. Option C is incorrect because the sterile dressing should be placed at least 1.25 cm away from the edge of the sterile field to maintain its sterility. Option D is incorrect because the sterile field should be set up above waist level to prevent potential contamination from reaching the field.
