Question 1 of 5
The bronchospasm and dyspnea are clinical manifestation of organophosphorus poisoning are caused by :
Correct Answer: A
Rationale: The bronchospasm and dyspnea seen in organophosphorus poisoning are primarily caused by the muscarinic action of the toxic substance. Organophosphates inhibit acetylcholinesterase, leading to an excess of acetylcholine at the neuromuscular junctions. This results in overstimulation of muscarinic receptors, causing symptoms such as bronchoconstriction, increased secretions, and respiratory distress. Nicotinic actions primarily lead to muscle weakness and paralysis, while CNS actions can cause seizures and altered mental status. So, in the case of bronchospasm and dyspnea, the muscarinic action is the main contributing factor.
Question 2 of 5
Which characteristic is representative of the newborn's gastrointestinal tract?
Correct Answer: D
Rationale: The characteristic representative of the newborn's gastrointestinal tract is that the intestines are shorter in relation to the body size. This is because a newborn's gastrointestinal tract is still developing and adapting to the digestion and absorption of nutrients. The proportion of the intestines to the body size is smaller in newborns compared to adults. Over time, as the newborn grows and matures, the intestines will also lengthen and increase in capacity to efficiently process food and absorb nutrients.
Question 3 of 5
What term describes irregular areas of deep blue pigmentation seen predominantly in newborns of African, Asian, Native American, or Hispanic descent?
Correct Answer: C
Rationale: Mongolian spots are irregular areas of deep blue pigmentation commonly seen in newborns of African, Asian, Native American, or Hispanic descent. They are flat, benign, and usually appear on the lower back or buttocks, but can also occur on other parts of the body. Mongolian spots are caused by pigment that is trapped deep in the layers of the skin and tend to fade over time, usually by the age of 5 or 6, although they may persist into adulthood in some cases. It is important for healthcare providers to be aware of Mongolian spots to differentiate them from other skin conditions and provide reassurance to parents.
Question 4 of 5
A nurse is performing a gestational age assessment on a newborn. The nurse determines that the newborn is "term" if which findings are assessed? (Select all that apply.)
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The school nurse is conducting a class for school-age children on Lyme disease. Which is characteristic of Lyme disease?
Correct Answer: C
Rationale: Lyme disease is caused by a spirochete bacterium called Borrelia burgdorferi, which enters the skin through the bite of an infected deer tick. It is primarily transmitted to humans through the bite of infected black-legged ticks, commonly known as deer ticks. These ticks carry the bacterium in their gut and can transmit it to humans when they feed on blood. Therefore, Lyme disease is characterized by being caused by a spirochete that enters the skin through a tick bite. Option C is the correct answer in this case, as options A, B, and D do not accurately describe the characteristics of Lyme disease.
