Premature infants who exhibit 5 to 10 seconds of respiratory pauses followed by 10 to 15 seconds of compensatory rapid respiration are:.
Suffering from sleep or wakeful apnea.
Experiencing severe swings in blood pressure.
Trying to maintain a neutral thermal environment.
Breathing in a respiratory pattern common to premature infants.
The Correct Answer is D
This pattern is called periodic breathing and it is characterized by 5 to 10 seconds of respiratory pauses followed by 10 to 15 seconds of compensatory rapid respiration. It is a normal phenomenon that occurs primarily in premature infants of more than 24 hours of age. It is usually not of pathologic significance and does not require intervention.
Choice A is wrong because sleep or wakeful apnea is defined as a cessation of breathing for more than 20 seconds or less than 20 seconds with bradycardia or cyanosis.
Choice B is wrong because severe swings in blood pressure are not associated with periodic breathing, but rather with intraventricular hemorrhage or patent ductus arteriosus.
Choice C is wrong because trying to maintain a neutral thermal environment does not affect the respiratory pattern of premature infants.
Normal ranges for respiratory rate in premature infants are 40 to 60 breaths per minute. Normal ranges for oxygen saturation in premature infants are 88% to 92%.

Correct Answer is B
Explanation
The presence or absence of anxiety is a noninvasive assessment that the RN would perform to evaluate the patient’s psychological status and possible signs of hypovolemic shock.
Anxiety can indicate reduced cerebral perfusion due to blood loss and low blood pressure.
Choice A is wrong because pulse oximetry is a noninvasive assessment that the RN would perform to measure the oxygen saturation of the patient’s blood, not the circulatory status.
Choice B is wrong because heart sounds are a noninvasive assessment that the RN would perform to auscultate the cardiac rhythm and rate of the patient, not the circulatory status.
Choice C is wrong because arterial pulses are a noninvasive assessment that the RN would perform to palpate the strength and quality of the patient’s peripheral pulses, not the circulatory status.
Choice D is wrong because skin color, temperature, and turgor are noninvasive assessments that the RN would perform to observe the skin integrity and hydration of the patient, not the circulatory status.
Normal ranges for pulse oximetry are 95% to 100%, for heart rate, are 60 to 100 beats per minute, and for blood pressure are 120/80 mmHg.
Correct Answer is ["A","B"]
Explanation
Pitocin and Methergine are both medications used to manage postpartum hemorrhage (PPH) by causing the uterus to contract and reduce bleeding. Pitocin is the most effective and preferred medication for PPH prevention and treatment.
Choice C is wrong because Terbutaline is a medication that relaxes the uterus and is used to stop preterm labor, not PPH.
Choice D is wrong because Hemabate is a brand name for carboprost, which is a prostaglandin that can be used for PPH, but it has more side effects and contraindications than Pitocin or Methergine.
Choice E is wrong because Magnesium sulfate is a medication that prevents seizures in women with preeclampsia or eclampsia, not PPH.
