Nursing Elites

1. 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.

2. A male client with heart failure calls the clinic and reports that he cannot put his shoes on because they are too tight. Which additional information should the nurse obtain?

• A. What time he took his medication?
• B. Has his weight changed in the last several days?
• C. Is he still able to tighten his belt buckle?
• D. How many hours he slept last night?

Correct answer: B

Rationale: The correct answer is B: 'Has his weight changed in the last several days?' Sudden weight gain can indicate fluid retention, which is a common symptom of worsening heart failure. The inability to put on tight shoes can be due to fluid retention leading to swelling in the feet and ankles. Choices A, C, and D do not directly address the potential fluid retention issue and are less relevant in this scenario.

3. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?

• A. Inflammation of the synovial membrane.
• B. Degeneration of the cartilage in the joint.
• C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
• D. Formation of uric acid crystals in the joint space.

Correct answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

4. 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.

5. How should the nurse record the observation of a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands?

• A. Hand assistance
• B. Leg crawling
• C. Gowers sign
• D. Bright sign

Correct answer: C

Rationale: The correct term for a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands is known as the Gowers sign. This maneuver is characteristic of Duchenne muscular dystrophy due to proximal muscle weakness. Choices A, B, and D are incorrect because they do not specifically describe the action of walking up the thighs with the hands, which is a distinctive feature of the Gowers sign.
