A nurse is teaching an assistive personnel to measure a newborn's respiratory rate. Which of the following statements indicates an understanding of why the respiratory rate should be counted for a complete minute?
Newborns are abdominal breathers.
Activity will increase the respiratory rate.
The rate and rhythm of breath are irregular in newborns.
Newborns do not expand their lungs fully with each respiration.
The Correct Answer is C
Choice A) Newborns are abdominal breathers is incorrect because this is not a reason why the respiratory rate should be counted for a complete minute, but rather a characteristic of how newborns breathe. Abdominal breathing means that the diaphragm and the abdominal muscles are the main muscles used for breathing, rather than the chest muscles. Newborns are abdominal breathers because their chest wall is more compliant and less stable than adults, and their intercostal muscles are not fully developed. Abdominal breathing does not affect the accuracy or duration of measuring the respiratory rate, as long as the abdomen is visible and palpable. Therefore, this response is irrelevant and inaccurate.
Choice B) Activity will increase the respiratory rate is incorrect because this is not a reason why the respiratory rate should be counted for a complete minute, but rather a factor that can influence the respiratory rate. Activity means any physical or mental exertion that requires more oxygen and energy from the body. Activity can increase the respiratory rate, as well as the heart rate and blood pressure, to meet the increased oxygen demand and carbon dioxide removal. However, activity does not affect the accuracy or duration of measuring the respiratory rate, as long as the newborn is calm and resting during the measurement. Therefore, this response is irrelevant and inaccurate.
Choice C) The rate and rhythm of breath are irregular in newborns is correct because this is a reason why the respiratory rate should be counted for a complete minute. The rate and rhythm of breath refer to how fast and how regularly one breathes. Newborns have an irregular rate and rhythm of breath, which means that they breathe at different speeds and intervals, sometimes pausing for a few seconds between breaths. This is normal and harmless for newborns, as long as they do not stop breathing for more than 20 seconds or show signs of distress. However, it can make it difficult to measure the respiratory rate accurately, as counting for a shorter period may not reflect the true average rate. Therefore, counting for a complete minute can ensure a more reliable measurement. Therefore, this response is clear and accurate.
Choice D) Newborns do not expand their lungs fully with each respiration is incorrect because this is not a reason why the respiratory rate should be counted for a complete minute, but rather a feature of how newborns breathe.
Lung expansion means how much air one inhales and exhales with each breath. Newborns do not expand their lungs fully with each respiration, because they have smaller lung volumes and capacities than adults, and they breathe more shallowly and rapidly. However, lung expansion does not affect the accuracy or duration of measuring the respiratory rate, as long as the chest or abdomen movement is visible and palpable. Therefore, this response is irrelevant and inaccurate.

Correct Answer is D
Explanation
Choice A) Report of absent breast pain is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the client does not have mastitis or engorgement. Mastitis is an infection of the breast tissue that causes pain, swelling, redness, and fever. Engorgement is a condition where the breasts become overfilled with milk, causing pain, hardness, and leakage. Both conditions are common in postpartum women who are breastfeeding, but they are not related to methylergonovine or uterine bleeding. Therefore, this response is irrelevant and inaccurate.
Choice B) Increase in lochia is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the medication was ineffective or that the client has a complication. Lochia is the vaginal discharge that consists of blood, mucus, and tissue from the uterus after childbirth. It usually lasts for about 4 to 6 weeks and gradually decreases in amount and color. Methylergonovine is a medication that helps to control uterine bleeding by improving the tone and contractions of the uterus. An increase in lochia may mean that methylergonovine did not work well or that the client has a problem such as retained placenta, infection, or subinvolution. Therefore, this response is opposite and inaccurate.
Choice C) Increase in blood pressure is incorrect because this is not a finding that indicates that the medication was effective, but rather a finding that indicates that the client has a side effect or a risk factor. Blood pressure is the force of blood against the walls of the arteries. It is measured by two numbers: systolic (the pressure when the heart beats) and diastolic (the pressure when the heart rests). The normal range for blood pressure is 120/80 mm Hg or lower. Methylergonovine is a medication that can cause vasoconstriction, which means narrowing of the blood vessels and increasing of the blood pressure. This can lead to complications such as hypertension, stroke, or heart attack. Therefore, this response is adverse and inaccurate.
Choice D) Fundus firm to palpation is correct because this is a finding that indicates that the medication was effective and that the client has a good outcome. The fundus is the upper part of the uterus that can be felt through the abdomen after childbirth. It should be firm, midline, and at or below the level of the navel. A firm fundus means that the uterus has contracted well and stopped bleeding. Methylergonovine is a medication that helps to achieve this by improving the tone and contractions of the uterus. Therefore, this response is positive and accurate.
Correct Answer is B
Explanation
Choice A) Increased urinary output: This is not a sign of sepsis in newborns. In fact, sepsis can cause reduced urinary output due to poor blood flow to the kidneys and dehydration.
Choice B) Hypothermia: This is a sign of sepsis in newborns. Sepsis can cause changes in temperature, often fever, but sometimes low temperature. Hypothermia can indicate a severe infection that affects the body's ability to regulate its temperature.
Choice C) Wakefulness: This is not a sign of sepsis in newborns. Sepsis can cause reduced activity and lethargy due to inflammation and organ dysfunction.
Choice D) Interest in feeding: This is not a sign of sepsis in newborns. Sepsis can cause reduced sucking and difficulty feeding due to poor appetite, nausea, vomiting, and abdominal distension.
