Adult Health 2 Exam 1
1. The nurse is caring for a client with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?
- A. Perform hand hygiene before and after handling the catheter
- B. Change the catheter every 72 hours
- C. Apply antibiotic ointment at the insertion site
- D. Irrigate the catheter daily
Correct answer: A
Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.
2. The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?
- A. Deltoid muscle
- B. Inner forearm
- C. Abdomen
- D. Thigh
Correct answer: B
Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
3. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?
- A. Increases heart rate
- B. Lowers blood pressure
- C. Dilates coronary arteries
- D. Reduces myocardial oxygen demand
Correct answer: C
Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
4. A client is admitted with a diagnosis of pneumonia. Which intervention should the nurse implement to promote airway clearance?
- A. Administer bronchodilators as prescribed.
- B. Encourage increased fluid intake.
- C. Perform chest physiotherapy.
- D. Provide humidified oxygen.
Correct answer: B
Rationale: Encouraging increased fluid intake is the most appropriate intervention to promote airway clearance in a client with pneumonia. Adequate hydration helps to thin respiratory secretions, making it easier for the client to cough up and clear the airways. Administering bronchodilators (Choice A) may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy (Choice C) can be beneficial in certain cases but may not be the initial intervention for promoting airway clearance. Providing humidified oxygen (Choice D) can help improve oxygenation but does not specifically target airway clearance in pneumonia.
5. A client is admitted to the hospital with second and third degree burns to the face and neck. How should the nurse best position the client to maximize function of the neck and face and prevent contracture?
- A. The neck extended backward using a rolled towel behind the neck
- B. Prone position using pillows to support both arms outward from the torso
- C. Side-lying position using pillows to support the abdomen and back
- D. The neck forward using pillows under the head and sandbags on both sides
Correct answer: D
Rationale: After sustaining burns to the face and neck, positioning is crucial to maintain functional posture, reduce pain, and prevent contractures. Placing the neck forward using pillows under the head and sandbags on both sides is the best option in this scenario. This position helps prevent neck and facial contractures, allowing for optimal function and healing. Choices A, B, and C do not adequately address the specific needs of a client with burns to the face and neck. Choice A could potentially exacerbate neck contractures, Choice B focuses on arm support rather than neck and face positioning, and Choice C does not directly address the needs of the burned face and neck, making them less effective in preventing contractures in these critical areas.
