Nursing Elites

1. When teaching bleeding precautions to a client with leukemia, the PN should include which of the following instructions?

• A. Use a soft toothbrush.
• B. Use dental floss daily.
• C. Hold pressure on any scrapes for 1-2 minutes.
• D. Use a triple-edged razor.

Correct answer: A

Rationale: The correct answer is to 'Use a soft toothbrush.' A soft toothbrush is recommended because it is less likely to cause the gums to bleed in clients with leukemia, who are at risk of bleeding due to overcrowding of white cells at the expense of other cell types like platelets. Choice B, 'Use dental floss daily,' is incorrect because dental floss is contraindicated and can make the gums bleed in clients with leukemia. Choice C, 'Hold pressure on any scrapes for 1-2 minutes,' is incorrect because when clotting is impaired, pressure should be held for 5-10 minutes or longer until the bleeding stops. Choice D, 'Use a triple-edged razor,' is incorrect because an electric razor should be used instead of a triple-edged razor to prevent small cuts and bleeding in clients with leukemia.

2. The nurse is preparing for a dressing change on a full thickness burn to the flank area. The orders include irrigating the wound with each dressing change. To irrigate the wound, what will the nurse use?

• A. Sterile saline
• B. Distilled water
• C. Betadine scrub
• D. Tap water

Correct answer: A

Rationale: When irrigating a wound, especially in the case of a full-thickness burn, it is crucial to use a solution that is gentle and non-irritating to the tissues. Sterile saline is the preferred choice for wound irrigation as it is isotonic and does not cause additional damage to the already compromised tissue. Distilled water lacks the electrolytes present in saline, Betadine scrub is not used for irrigation due to its potential to be cytotoxic, and tap water may introduce contaminants and microorganisms to the wound.

3. A client has chronic respiratory acidosis caused by end-stage chronic obstructive pulmonary disease (COPD). Oxygen is delivered at 1 L/min via nasal cannula. The nurse teaches the family that the reason for this is to avoid respiratory depression, based on which of the following explanations?

• A. COPD clients are stimulated to breathe by hypoxia.
• B. COPD clients depend on a low carbon dioxide level.
• C. COPD clients tend to retain hydrogen ions if they are given high doses of oxygen.
• D. COPD clients thrive on a high oxygen level.

Correct answer: A

Rationale: In clients with COPD and chronic respiratory acidosis, they are compensating for low oxygen and high carbon dioxide levels. Hypoxia acts as the main stimulus to breathe in individuals with chronic hypercapnia. When oxygen is administered, it can decrease the respiratory drive by eliminating the hypoxic drive and reducing the stimulus to breathe. Therefore, delivering oxygen at 1 L/min via nasal cannula helps prevent respiratory depression by maintaining the hypoxic drive to breathe. The other options are incorrect: COPD clients do not depend on a low carbon dioxide level as they are chronically hypercapnic, they do not retain hydrogen ions with high oxygen doses, and they do not thrive on a high oxygen level.

4. Which microorganism is most commonly associated with gastritis?

• A. Syphilis
• B. Cytomegalovirus
• C. H. pylori
• D. Mycobacterium

Correct answer: C

Rationale: H. pylori is the most common microorganism associated with gastritis, present in over 80% of cases. While syphilis, cytomegalovirus, and mycobacterium can also cause gastritis, they are much less prevalent compared to H. pylori. Therefore, the correct answer is H. pylori.

5. A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:

• A. nitrous oxide.
• B. nitrogen.
• C. nitric oxide.
• D. nitrogen dioxide.

Correct answer: A

Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.
