Nursing Elites

1. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

• A. 2 liters/minute
• B. 4 liters/minute
• C. 6 liters/minute
• D. 8 liters/minute

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

2. After receiving a recent tattoo, someone should be screened for:

• A. tuberculosis.
• B. herpes.
• C. hepatitis.
• D. syphilis.

Correct answer: C

Rationale: After receiving a recent tattoo, screening for hepatitis is crucial due to the risk of blood-borne hepatitis B or C if strict sterile procedures are not followed during the tattooing process. Tuberculosis is an airborne pathogen and is not directly related to receiving a tattoo. Herpes and syphilis are infections spread through direct contact, such as sexual contact, and are not typically associated with tattooing.

3. All of the following tasks could be delegated to a nursing assistant or unlicensed assistive personnel (UAP) except:

• A. monitoring intravenous infusion
• B. assisting a client to the bathroom
• C. offering fluid intake every 1-2 hours
• D. monitoring/recording the amount of fluid taken

Correct answer: A

Rationale: Monitoring an intravenous infusion involves assessing for complications, adjusting the flow rate, and monitoring the client's response, which requires the knowledge and skills of a licensed nurse (RN or LPN). Tasks that can be delegated to nursing assistants or unlicensed assistive personnel include assisting a client to the bathroom, offering fluids, and recording fluid intake. These activities are within the scope of practice for UAPs as they do not involve the specialized knowledge and training needed for intravenous infusion monitoring.

4. What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1�F at 4 a.m.?

• A. delta sleep
• B. slow brain waves
• C. pneumonia
• D. circadian rhythm

Correct answer: D

Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1�F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.

5. A child comes to the clinic with a skin rash. The maculopapular lesions are distributed around the mouth and have honey-colored drainage. The caregiver states that the rash is getting worse and seems to spread with the child's scratching. Which of the following advisory comments should be given?

• A. The history and presentation might indicate chickenpox, a highly contagious disease.
• B. The lesions might indicate a noncontagious infection that does not require isolation.
• C. The history and presentation might indicate an infectious illness called impetigo.
• D. The lesions are not contagious unless others have open wounds or lesions themselves.

Correct answer: C

Rationale: The scenario describes classic impetigo, which typically presents with maculopapular lesions around the mouth with honey-colored drainage, worsening with scratching. It is important to advise the caregiver that the history and presentation are indicative of impetigo, an infectious skin condition caused by bacteria. Treatment usually involves antibiotic therapy. Choice A is incorrect because chickenpox typically presents with a vesicular rash following a history of high fever. Choice B is incorrect as impetigo is contagious and requires precautions to prevent the spread of infection. Choice D is incorrect as impetigo is contagious irrespective of open wounds or lesions in others.
