Nursing Elites

1. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?

• A. Neutralizes stomach acid
• B. Decreases gastric acid secretion
• C. Covers the ulcer site and protects it from acid
• D. Improves gastric motility

Correct answer: C

Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.

2. What is the best position for a client experiencing a nosebleed?

• A. Sitting up and leaning forward
• B. Lying flat with a pillow under the head
• C. Sitting up and leaning back
• D. Lying on the side with the head elevated

Correct answer: A

Rationale: The best position for a client experiencing a nosebleed is sitting up and leaning forward. This position helps prevent blood from flowing down the throat and reduces the risk of aspiration. Choice B is incorrect as lying flat can lead to blood flowing down the throat. Choice C is also incorrect because leaning back may cause blood to flow backward into the throat. Choice D is incorrect as lying on the side with the head elevated is not the optimal position to manage a nosebleed effectively.

3. A healthcare worker with no known exposure to tuberculosis has received a Mantoux tuberculosis skin test. The nurse's assessment of the test after 62 hours indicates 5mm of erythema without induration. Which is the best initial nursing action?

• A. Review the healthcare worker's history for possible exposure to TB.
• B. Instruct the healthcare worker to return for a repeat test in 1 week.
• C. Refer the healthcare worker to a healthcare provider for isoniazid (INH) therapy.
• D. Document negative results in the healthcare worker's medical record.

Correct answer: D

Rationale: A Mantoux tuberculosis skin test without induration is considered negative. In this case, with 5mm of erythema and no induration, the result is negative, indicating no current infection. The best initial nursing action is to document these negative results in the healthcare worker's medical record. Reviewing the history for possible exposure to TB is unnecessary as the test result is negative. Instructing the healthcare worker to return for a repeat test or referring for INH therapy is not warranted when the test is negative.

4. A client is admitted to the emergency department with symptoms of arm numbness, chest pain, and nausea/vomiting. The examining healthcare provider believes that the client has experienced an acute myocardial infarction (AMI) within the past three hours and would like to initiate tissue plasminogen activator (tPA) therapy. Which client history findings contraindicate the use of tPA?

• A. Treats hypoglycemia with an oral hypoglycemic agent.
• B. Had a cerebrovascular hemorrhage 2 months ago.
• C. Current age 65, father died of MI at 55.
• D. Report of being intolerant of medication that contains aspirin.

Correct answer: B

Rationale: A history of cerebrovascular hemorrhage is a contraindication for tPA therapy due to the risk of bleeding. Choice A is incorrect because treating hypoglycemia with an oral hypoglycemic agent is not a contraindication for tPA therapy. Choice C is incorrect as age and family history of MI do not contraindicate the use of tPA. Choice D is incorrect as being intolerant of medication containing aspirin is not a contraindication for tPA therapy.

5. The healthcare provider writes several prescriptions for a client diagnosed with hospital-acquired pneumonia (HAP) that include a combination of broad-spectrum antibiotics. Which intervention should the nurse implement first?

• A. Administer the first dose of antibiotics.
• B. Obtain a chest X-ray.
• C. Administer oxygen therapy.
• D. Collect blood specimens for culture prior to starting antibiotic therapy.

Correct answer: D

Rationale: Collecting blood specimens for culture prior to starting antibiotic therapy is the priority intervention in a client diagnosed with hospital-acquired pneumonia. This step is crucial to identify the causative organism responsible for the infection and ensure that the antibiotics prescribed are appropriate for effective treatment. Administering antibiotics before collecting cultures may interfere with the accuracy of culture results, potentially leading to inappropriate treatment. While administering the first dose of antibiotics is important, obtaining a chest X-ray and administering oxygen therapy are secondary interventions compared to identifying the causative organism through blood cultures.
