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?

Choice a) This could result in profound bleeding is correct because this is the primary reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination involves inserting a gloved finger or a speculum into the vagina and cervix to assess their dilation, effacement, position, and station. This can cause trauma to the cervix or the placenta, which can trigger severe hemorrhage and endanger the mother and the fetus. Therefore, this explanation is accurate and appropriate.

Choice b) This could initiate preterm labor is incorrect because this is not the main reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may stimulate uterine contractions, which can lead to preterm labor and delivery. However, this is not the most serious or likely complication of an internal examination for a client who has placenta previa, as the bleeding risk is much higher and more urgent. Therefore, this explanation is incomplete and misleading.

Choice c) There is an increased risk of introducing infection is incorrect because this is not a specific reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may introduce bacteria or other microorganisms into the vagina or cervix, which can cause infection and inflammation. However, this is a general risk that applies to any pregnant woman who undergoes an internal examination, not just those who have placenta previa. Therefore, this explanation is irrelevant and inaccurate.

Choice d) There is an increased risk of rupture of the membranes is incorrect because this is not a relevant reason why an internal examination should be avoided for a client who has placenta previa. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. An internal examination may cause rupture of the membranes, which are the sacs that contain the amniotic fluid and the fetus. However, this is not a significant or common complication of an internal examination for a client who has placenta previa, as the membranes are usually located above or away from the placenta and cervix. Therefore, this explanation is improbable and inaccurate.

Choice a) Document the event in the nurses' notes is incorrect because this is not a priority action for a neonate who is showing signs of hypoglycemia. Hypoglycemia is a condition where the blood glucose level is lower than normal, which can cause neurological and metabolic problems in newborns. Neonates of diabetic mothers are at higher risk of developing hypoglycemia due to increased insulin production and decreased glycogen stores.

Documenting the event in the nurses' notes is an important step, but it should be done after assessing and treating the neonate's condition.

Choice b) Test for blood glucose level is correct because this is the most important action for a neonate who is exhibiting symptoms of hypoglycemia. The nurse should use a heel stick or a cord blood sample to measure the blood glucose level of the neonate as soon as possible, as hypoglycemia can lead to serious complications such as seizures, coma, brain damage, or death if left untreated. The normal blood glucose range for a full-term neonate is 40 to 60 mg/dL in the first hour of life, and 50 to 90 mg/dL thereafter. A blood glucose level below 40 mg/dL indicates hypoglycemia and requires immediate intervention.

Choice c) Notify the clinician stat is incorrect because this is not the most urgent action for a neonate who is suffering from hypoglycemia. The nurse should notify the clinician after confirming the diagnosis of hypoglycemia and initiating treatment, such as feeding or administering intravenous glucose. The clinician may order further tests or treatments depending on the severity and cause of the hypoglycemia, but the nurse should not delay the initial management of the neonate's condition.

Choice d) Start an intravenous line with D5W is incorrect because this is not the first-line treatment for a neonate who has hypoglycemia. D5W stands for dextrose 5% in water, which is a solution that contains glucose and water. It can be used to treat hypoglycemia by providing a source of energy and fluid to the neonate. However, before starting an intravenous line with D5W, the nurse should first attempt to feed the neonate with breast milk or formula, as this can also raise the blood glucose level and provide other nutrients and antibodies. If feeding is unsuccessful or contraindicated, then the nurse should start an intravenous line with D5W as ordered by the clinician.
