Nursing Elites

1. How can light therapy be effective?

• A. Improving weight problems.
• B. Assisting with allergies.
• C. Using in alternative medical treatments.
• D. Working with sleep patterns.

Correct answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy may have other potential benefits, such as improving mood or helping with seasonal affective disorders, the main focus and effectiveness of light therapy are commonly linked to regulating sleep patterns. Therefore, the correct answer is 'Working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not primarily used for overcoming weight problems, helping with allergies, or solely as an alternative medical treatment.

2. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

3. While undergoing hemodialysis, the client becomes restless and tells the nurse he has a headache and feels nauseous. Which of the following complications does the nurse suspect?

• A. Infection.
• B. Disequilibrium syndrome.
• C. Air embolus.
• D. Infection.

Correct answer: C

Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.

4. The client is wheezing and struggling to breathe. Which of the inhaled medications is indicated at this time?

• A. Fluticasone (Flovent)
• B. Salmeterol (Serevent)
• C. Theophylline (Theodur)
• D. Albuterol (Atrovent)

Correct answer: D

Rationale: The correct answer is Albuterol (Atrovent) because it is a rapid-acting bronchodilator, essential for a client experiencing wheezing and difficulty breathing. Albuterol acts quickly, dilating the airways and providing immediate relief in cases of respiratory distress. Fluticasone (Flovent) and Salmeterol (Serevent) are maintenance medications for long-term asthma control, not suitable for acute situations described. Theophylline (Theodur) is a bronchodilator but with a slower onset compared to Albuterol, making it less appropriate for a client in immediate distress.

5. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?

• A. A three-hour-old just waking up after a period of sleep
• B. A two-day-old crying loudly
• C. A three-day-old two hours after circumcision
• D. A one-hour-old sucking his fist

Correct answer: A

Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.
