Question 1 of 5
Which oxygen delivery system would provide the highest concentrations of oxygen to the client?
Correct Answer: C
Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
Question 2 of 5
When teaching the client with tuberculosis about follow-up home care, the nurse should emphasize that a laboratory appointment for which of the following lab tests is critical?
Correct Answer: A
Rationale: The nurse should emphasize the importance of monitoring liver function tests in clients taking INH due to the risk of hepatocellular injury and hepatitis associated with this medication. Regular assessment of liver enzymes can help detect liver damage early. Monitoring kidney function, blood sugar levels, or cardiac enzymes is not specifically required for clients taking INH and tuberculosis treatment.

Question 4 of 5
The nurse is caring for a 2-year-old who is being treated with chelation therapy, calcium disodium edetate, for lead poisoning. The nurse should be alert for which of the following side effects?
Correct Answer: C
Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.
Question 5 of 5
A newborn is having difficulty maintaining a temperature above 98 degrees Fahrenheit and has been placed in a warming isolette. Which action is a nursing priority?
Correct Answer: B
Rationale: When a newborn is placed in a warming isolette due to difficulty maintaining temperature, the priority action is to continuously monitor the neonate's temperature to prevent overheating. Using heat lamps is unsafe as their temperature cannot be regulated, potentially causing harm. Warming medications and fluids before administration is not necessary in this situation. While touching the neonate with cold hands may startle them, it does not pose a safety risk compared to monitoring and controlling the temperature.
