Which of the following findings is abnormal?

Correct Answer: B

Rationale: A heart rate of 80 beats per minute in a 3-month-old infant is abnormally low for that age group and could indicate underlying health issues. The normal heart rate for a 3-month-old infant is typically higher, around 100-150 beats per minute. Therefore, this finding stands out as abnormal and warrants further evaluation. Choice A is not necessarily abnormal in a newly born infant as irregular breathing patterns can be common during the neonatal period. Choice C falls within the normal respiratory rate range for a 2-year-old child, which is around 20-30 breaths per minute. Choice D reflects a systolic blood pressure value within the normal range for a 10-year-old child, which is typically around 90-110 mm Hg.

Correct Answer: C

Rationale: When encountering a situation where the umbilical cord is wrapped around a baby's neck upon delivery, the initial treatment should involve trying to remove the cord from around the neck gently. It is crucial to handle this situation delicately to avoid causing harm to the baby. Attempting to ease the cord over the baby's head without pulling or tightening can help prevent potential complications associated with cord compression. Choice A, clamping and cutting the umbilical cord, is not recommended as it can lead to abrupt deprivation of oxygen to the baby. Choice B, gently pulling on the cord, can worsen the situation by tightening the cord around the baby's neck. Choice D, keeping the cord moist and providing rapid transport, is not the immediate concern and does not address the potential risks of cord compression during delivery. Therefore, the priority is to carefully attempt to remove the cord from around the baby's neck to ensure a safe delivery.

Correct Answer: D

Rationale: When assessing a small child's level of responsiveness, the most appropriate method is to tap the child and shout, 'Are you okay?' This approach is more likely to elicit a response from the child, providing a direct assessment of their level of consciousness and responsiveness. Palpating for a radial pulse (Choice A) is not the most direct method for assessing responsiveness in a child. Shouting at the child (Choice B) may startle them and not provide an accurate assessment. Asking the parent (Choice C) does not directly evaluate the child's responsiveness.

Correct Answer: A

Rationale: The most appropriate question to ask when assessing a geriatric patient who may have experienced an acute ischemic stroke is when the symptoms were first noticed. This information is crucial for determining the time window for potential treatments like thrombolytic therapy, as prompt intervention is necessary for stroke management. Option B is not as relevant in the acute assessment of stroke, though important for overall health history. Option C is important but may not be as time-sensitive as determining symptom onset. Option D focuses on a different cardiac event, not directly related to the current concern of a possible stroke.

Correct Answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

Correct Answer: B

Rationale: A heart rate of 80 beats per minute in a 3-month-old infant is abnormally low for that age group and could indicate underlying health issues. The normal heart rate for a 3-month-old infant is typically higher, around 100-150 beats per minute. Therefore, this finding stands out as abnormal and warrants further evaluation. Choice A is not necessarily abnormal in a newly born infant as irregular breathing patterns can be common during the neonatal period. Choice C falls within the normal respiratory rate range for a 2-year-old child, which is around 20-30 breaths per minute. Choice D reflects a systolic blood pressure value within the normal range for a 10-year-old child, which is typically around 90-110 mm Hg.

Correct Answer: B

Rationale: In obstetrics, gravida indicates the number of pregnancies, including the current one. Para indicates the number of pregnancies carried to viability (20 weeks or more). Since the patient has been pregnant twice but only carried one pregnancy past 20 weeks, her obstetric history should be documented as gravida 2, para 0. The miscarriage at 19 weeks does not contribute to the para count. Choice A (gravida 2, para 1) would indicate that she has had two pregnancies with one resulting in a live birth, which is incorrect. Choice C (gravida 1, para 1) would indicate that she has had one pregnancy with one live birth, which does not reflect her obstetric history. Choice D (gravida 0, para 2) would indicate that she has never been pregnant past 20 weeks, which is also inaccurate.

Correct Answer: D

Rationale: Bruising to the upper back is more suspicious for child abuse compared to the other listed injuries. In young children, injuries like bruises to the upper back are less likely to be accidental and may raise concerns about physical abuse. The upper back is an area less prone to accidental injuries during play or falls. Multiple bruises to the shins are common in active children. A burned hand with splash marks may suggest accidental burns. A small laceration to the chin is also a common injury from falls in children. Therefore, the bruising on the upper back is more concerning for possible child abuse.

Correct Answer: B

Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.
