EMT Intermediate 99 - Exam Topics Sample Questions

In terms of the Apgar score, if a newborn infant has a pulse rate of less than 100 beats per minute, he or she would be assigned which of the following scores for pulse rate?

Correct Answer:
1


the apgar score, developed by dr. virginia apgar in 1952, is a quick test performed on a newborn at 1 and 5 minutes after birth. the score assesses the physical condition of a newborn and helps determine any immediate need for extra medical or emergency care. five criteria are used: heart rate (pulse), respiratory effort, muscle tone, reflex response, and skin coloration. each criterion is scored on a scale from 0 to 2, then summed up to get a total apgar score ranging from 0 to 10.

focusing specifically on the pulse rate component of the apgar score, newborns are evaluated on the strength and steadiness of their heartbeats. the scoring for this specific criterion is as follows: - a score of 0 is given if there is no pulse. - a score of 1 is assigned if the pulse rate is less than 100 beats per minute. - a score of 2 is awarded for a pulse rate greater than or equal to 100 beats per minute.

hence, if a newborn infant has a pulse rate of less than 100 beats per minute, they would be assigned a score of 1 for the pulse rate criterion within the apgar score. this reflects a pulse rate that is present but slower than the ideal rate of 100 or more beats per minute. this component of the scoring helps to quickly identify infants who might be struggling and might require interventions to stabilize their condition.

Which of the following is least likely to be a maternal change during pregnancy?

Correct Answer:
the ph of vaginal secretions increases because of the increased production of lactic acid from glycogen in the vaginal epithelium.
*p the question asks which among the changes listed is least likely to occur during pregnancy. the correct answer is: "the ph of vaginal secretions increases because of the increased production of lactic acid from glycogen in the vaginal epithelium." *p this statement is incorrect because, in reality, the ph of vaginal secretions actually decreases during pregnancy, not increases. normally, the vaginal environment is slightly acidic, with a ph ranging from about 3.8 to 4.5. during pregnancy, the ph typically becomes even more acidic, often dropping to around 3.5. this increase in acidity is indeed due to the higher production of lactic acid, which results from the action of lactobacilli bacteria on glycogen in the vaginal epithelium. the acidic environment is crucial as it helps in preventing the growth of harmful pathogens, thereby protecting both the mother and the fetus. *p the incorrect statement in the question may stem from a misunderstanding of how ph works. ph is a measure of the hydrogen ion concentration in a solution, where lower ph values represent higher acidity, and higher ph values indicate higher alkalinity. thus, saying that the ph increases (suggesting a move towards alkalinity) contradicts the actual physiological change where increased lactic acid production leads to a more acidic (lower ph) environment. *p in contrast, the other statements provided in the question reflect typical physiological changes during pregnancy. for example, the uterine size does indeed increase significantly during pregnancy – from about the size of a pear in its non-pregnant state to being large enough to hold a developing fetus, expanding way beyond the initial 70 g to potentially over 1 kg by term. additionally, increased vascularity causing a violet coloration of the vagina, known as chadwick's sign, is another common and observable change during pregnancy. *p understanding these physiological changes is important for healthcare providers as they monitor the health and progress of pregnancy, ensuring both maternal and fetal wellbeing. misunderstandings or inaccuracies like the one discussed can lead to confusion and misinterpretation of normal and abnormal signs during this critical period.
