Full Explanation
Ordered dose = 400 mg
Available = 500 mg in 1.2 mL
Step 1: Use the formula
Volume to administer = (Ordered dose ÷ Available dose) × Volume available
Step 2: Substitute the values
Volume = (400 ÷ 500) × 1.2
Step 3: Calculate
Volume = 0.8 × 1.2 = 0.96 mL

A 9-month-old infant presents with fever and irritability. The nurse notices the infant repeatedly pulls at the right ear, arches the back when touched, and grimaces during diaper changes. Which assessment BEST guides the nurse's interpretation of the infant's pain?
A. Behavioral cues, posture, and expressions help infer pain location and intensity.
Infants cannot verbally communicate pain, so nurses rely on observational cues. Pulling at the ear, arching the back, grimacing, and irritability are valid behavioral indicators of pain and help guide assessment of location and severity. Combining these with physiological signs, such as increased heart rate or changes in respiratory pattern, provides a comprehensive understanding of the infant’s pain.
B. Only physiological indicators reliably determine the presence and location of pain.
Physiological indicators like tachycardia, hypertension, or increased respiratory rate are nonspecific and may reflect stress, fever, or other illness, so relying solely on them is inadequate for pain assessment.
C. The infant's behaviors show generated distress: cannot locate pain without verbalization.
Infants cannot verbalize pain, but behavioral cues are well-recognized and validated indicators of pain. Assuming pain cannot be assessed without speech is inaccurate.
D. The infant's behaviors are exaggerated due to caregiver anxiety and attention-seeking.
Infants do not exhibit pain behaviors to manipulate caregivers. Behaviors such as ear pulling, back arching, and grimacing are genuine indicators of discomfort or pain and should be taken seriously.

A nurse is assessing a 3-year-old child's response to a new daycare environment. The child initially clings to the parent, cries, and takes several minutes to warm up to other children and new activities. Which statement BEST reflects the child's temperament?
A. The child's behavior indicates a delay in social development rather than temperament.
The behaviors described including initial clinginess, crying, and gradual adjustment, are typical variations in temperament, not indicators of a social developmental delay. Most 3-year-olds show a range of responses when exposed to new environments.
B. The child has a difficult temperament and is unlikely to ever adapt to new environments.
A difficult temperament is characterized by intense reactions, irregular routines, and high sensitivity, but the child in this scenario eventually warms up and engages with others, indicating the child is not persistently difficult.
C. The child has an easy temperament and adapts quickly to new situations.
Children with an easy temperament adjust rapidly, show positive mood, and require minimal guidance, which does not match the initial clinginess and crying observed in this child.
D. The child has a slow-to-warm-up temperament and requires time to adjust to new experiences.
Slow-to-warm-up children are cautious in unfamiliar situations, may initially withdraw or cling, and gradually adapt once they feel safe. The child’s behavior of crying, clinging, and taking several minutes to engage aligns with this temperament type.

A nurse is caring for a client who is at 36 weeks of gestation and who has a suspected placenta previa. Which of the following findings support this diagnosis?
A. Abdominal pain with scan red vaginal bleeding
Placenta previa typically presents with painless bleeding, not pain. Abdominal pain with bleeding is more suggestive of placental abruption, not previa.
B. Painless red vaginal bleeding
Placenta previa is characterized by bright red, painless vaginal bleeding during the second or third trimester, often without uterine tenderness or contractions. The bleeding occurs because the placenta implants over or near the cervical os, which disrupts vascular integrity as the cervix begins to efface or dilate.
C. Increasing abdominal pain with a rigid abdomen
This presentation is more consistent with abruptio placentae, where the placenta separates prematurely, leading to painful bleeding and a firm, tender uterus.
D. Intermittent abdominal pain following passage of bloody mucus
This describes bloody show, which is a sign of labor onset, not placenta previa. It is associated with cervical effacement and dilation rather than abnormal placental implantation.
