An alert older adult client with type 1 diabetes mellitus is admitted with a serum glucose of 420 mg/dL (23.31 mmol/L). As the nurse administers 10 units of regular insulin IV push (IVP), the client immediately begins to vomit. Which action should the nurse implement first?

Reference Range:

• Blood Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Early decelerations are characterized by a gradual, symmetrical decrease and return of the fetal heart rate (FHR) that coincides with the peak of a uterine contraction. This "mirror image" pattern is typically caused by fetal head compression, which triggers a vagal response during pushing or as the fetus descends through the birth canal. In most clinical scenarios, this is considered a benign finding and does not indicate fetal distress or hypoxia.

Rationale:

A. Late decelerations are gradual decreases in FHR that begin after the peak of the contraction and return to baseline only after the contraction has ended. This pattern is associated with uteroplacental insufficiency and is a concerning sign that the fetus is not receiving adequate oxygen during the period of reduced blood flow during a contraction.

B. Prolonged decelerations are characterized by a decrease in FHR from baseline that lasts at least 2 minutes but less than 10 minutes. These are often caused by more severe events, such as umbilical cord prolapse, maternal hypotension, or uterine tachysystole, and require immediate clinical intervention to prevent fetal compromise.

C. Early deceleration is the correct identification. Because the decline occurs when the client pushes and returns to baseline quickly (within 20 seconds), it matches the timing of a contraction exactly. This indicates the fetal head is being compressed against the cervix or pelvis, which is a normal part of the second stage of labor and does not typically require medical intervention.

D. Variable decelerations appear as an abrupt, "V" or "W" shaped decrease in FHR that is not necessarily tied to the timing of contractions. These are caused by umbilical cord compression. While common, they are distinct from the gradual, rhythmic pattern described in the scenario.

Brief introduction:

Preterm neonates born at 32 weeks exhibit physiological immaturity of the respiratory and neurological systems. Common clinical complications include surfactant deficiency leading to atelectasis and poor muscle tone reflecting incomplete neurological development and potential hypoxia.

Rationale:

A. Dry skin is an expected finding in some neonates and does not represent an acute physiological threat compared to respiratory or neurological concerns. Preterm skin is often translucent and thin rather than dry, but this does not require immediate follow up. It is managed with routine emollients and humidity.

B. Testicular rugae are actually expected to be absent or minimal in an infant born at 32 weeks gestation. The presence of undescended testes and smooth scrotal sac are normal developmental findings for this gestational age. This does not indicate an acute pathology requiring urgent medical or nursing intervention.

C. Decreased tone in a preterm infant is a significant finding that may indicate neurological distress, sepsis, or exhaustion from increased work of breathing. Normal infants should demonstrate flexed extremities and active movement. A limp posture requires immediate intervention to rule out metabolic instability or intracranial hemorrhage.

D. Mild tachypnea, defined as a respiratory rate > 60 breaths/minute, indicates the neonate is struggling to maintain gas exchange due to immature lung tissue. In preterm infants, this often precedes respiratory failure and requires constant monitoring of oxygen saturation levels. The nurse must assess if supplemental oxygen is sufficient to prevent further decompensation.

E. Thin lanugo is a normal physical characteristic of a neonate born at 32 weeks. Fine downy hair typically covers the back and shoulders of preterm infants and disappears as they approach full term status. Its presence confirms gestational age rather than suggesting an acute medical emergency or clinical complication.

F. Nasal flaring is a classic sign of respiratory distress as the infant attempts to decrease airway resistance and increase tidal volume. It is often accompanied by retractions or grunting in premature babies with low lung compliance. This physical finding suggests that the current 24% oxygen hood delivery may be inadequate for the infant.
