Nursing Elites

1. When speaking to young parents, the nurse states that lead poisoning is one of the most common preventable health problems affecting children. What condition occurs when the level of lead ingested exceeds the amount that can be absorbed by the bone?

• A. Malnutrition
• B. Anemia
• C. Bone pain
• D. Diarrhea

Correct answer: B

Rationale: The correct answer is B: Anemia. When the amount of lead ingested exceeds the amount that can be absorbed by the bone, it leads to anemia. Malnutrition (Choice A) is a state of inadequate nutrition, not directly related to lead poisoning. Bone pain (Choice C) is a symptom of lead poisoning due to its effects on bones but not directly related to lead ingestion exceeding absorption. Diarrhea (Choice D) is not a direct consequence of lead ingestion exceeding absorption by bones.

2. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

3. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?

• A. When the fever dissipates
• B. After the incubation period
• C. When the lesions have healed
• D. When the lesions are crusted over

Correct answer: D

Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.

4. A male client tells the nurse that he is experiencing burning on urination, and assessment reveals that he had sexual intercourse four days ago with a woman he casually met. Which action should the nurse implement?

• A. Observe the perineal area for a chancroid-like lesion.
• B. Obtain a specimen of urethral drainage for culture.
• C. Assess for perineal itching, erythema, and excoriation.
• D. Identify all sexual partners in the last four days.

Correct answer: B

Rationale: In this scenario, the most appropriate action for the nurse to take is to obtain a specimen of urethral drainage for culture. This procedure can help diagnose the cause of burning on urination, which could be indicative of a sexually transmitted infection. Option A, observing for a chancroid-like lesion, may not be the most immediate or relevant action in this case. Option C, assessing for perineal itching, erythema, and excoriation, is important but obtaining a culture specimen would provide more specific diagnostic information. Option D, identifying all sexual partners, is relevant for contact tracing but obtaining a culture specimen is the priority to determine the current infection status.

5. The healthcare provider is assessing a client with a chest tube. Which finding indicates that the chest tube is functioning properly?

• A. Continuous bubbling in the water seal chamber
• B. Tidaling in the water seal chamber
• C. Absence of drainage in the collection chamber
• D. Fluid level in the suction control chamber is below the prescribed level

Correct answer: B

Rationale: Tidaling in the water seal chamber indicates proper chest tube function. Tidaling refers to the rise and fall of fluid in the water seal with inhalation and exhalation, demonstrating the patency of the system. Continuous bubbling (Choice A) in the water seal chamber indicates an air leak. Absence of drainage in the collection chamber (Choice C) is not a desired finding as it suggests no drainage is occurring. A fluid level below the prescribed level in the suction control chamber (Choice D) may indicate inadequate suction.
