Nursing Elites

1. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

2. When a client reports being allergic to penicillin, which question should the nurse ask to gather more information?

• A. Are you allergic to any other medications?
• B. How often have you taken penicillin in the past?
• C. Is anyone else in your family allergic to penicillin?
• D. What happens to you when you take penicillin?

Correct answer: D

Rationale: Questioning the client about the specific allergic reaction to penicillin is crucial for assessing the severity and type of allergic response, aiding in determining appropriate treatment and avoiding potential adverse reactions.

3. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which instruction should the nurse provide?

• A. Avoid green leafy vegetables.
• B. Take aspirin for headaches.
• C. Use a soft-bristled toothbrush.
• D. Limit fluid intake to 1 liter per day.

Correct answer: C

Rationale: The correct instruction for a client on warfarin therapy, especially with a history of DVT, is to use a soft-bristled toothbrush. This is crucial to prevent gum bleeding, which is a risk due to the anticoagulant effects of warfarin. Green leafy vegetables are rich in vitamin K, which can interfere with warfarin's effectiveness, so they should be consumed consistently to maintain a balance. Aspirin is not recommended for headaches in clients on warfarin due to the increased risk of bleeding. Limiting fluid intake is not a standard instruction for clients on warfarin therapy.

4. An elderly female client comes to the clinic for a regular check-up. The client tells the nurse that she has increased her daily doses of acetaminophen (Tylenol) for the past month to control joint pain. Based on this client's comment, what previous lab values should the nurse compare with today's lab report?

• A. Look at last quarter's hemoglobin and hematocrit to assess for dehydration.
• B. Look for an increase in today's LDH compared to the previous one to assess for possible liver damage.
• C. Expect to find an increase in today's APTT compared to last quarter's due to bleeding.
• D. Determine if there is a decrease in serum potassium due to renal compromise.

Correct answer: B

Rationale: When a client increases their daily doses of acetaminophen for joint pain, it raises concerns about possible liver damage due to acetaminophen overdose. LDH (Lactate Dehydrogenase) levels can indicate liver function, so comparing today's levels with previous ones can help assess for liver damage caused by acetaminophen overuse.

5. A client with a history of asthma is prescribed salmeterol (Serevent). Which instruction should the nurse provide?

• A. Use this medication for acute asthma attacks.
• B. Use this medication before using your albuterol inhaler.
• C. Use this medication twice daily for long-term control.
• D. Use this medication as needed for wheezing.

Correct answer: C

Rationale: The correct instruction for a client prescribed salmeterol (Serevent) is to use it twice daily for long-term control. Salmeterol is a long-acting bronchodilator that is not intended for acute asthma attacks or as-needed use for wheezing. Choice A is incorrect because salmeterol is not used for acute asthma attacks. Choice B is incorrect as salmeterol is not meant to replace the albuterol inhaler but rather used for long-term control. Choice D is incorrect because salmeterol should not be used as needed; it is a maintenance medication for asthma.
