A 5.6 kg patient is receiving digoxin by mouth every 8 hours. The safe dose is 0.03-0.06 mg/kg/day. What is the maximum safe dose for this patient? (Round to the nearest hundredth.)
The Correct Answer is ["0.34"]
Given:
- Patient weight = 5.6 kg
- Safe dose = 0.03–0.06 mg/kg/day
Step 1: Use the formula for maximum safe dose
Maximum dose = Weight × Maximum mg/kg/day
Step 2: Substitute the values
Maximum dose = 5.6 × 0.06
Step 3: Calculate
Maximum dose = 0.336 mg/day
Step 4: Round to the nearest hundredth
Maximum dose = 0.34 mg/day

Correct Answer is D
Explanation
A. Developmental milestones follow predictable sequences, but the exact age at which each child reaches them can vary. Expecting all babies to reach milestones at the same age is unrealistic and does not reflect normal variation in growth and development.
B. While gross motor skills like walking often develop alongside fine motor skills, fine motor development does not occur automatically. It requires practice, coordination, and maturation of muscles and nervous system pathways.
C. Genetics play a significant role in growth, influencing height, weight, body proportions, and sometimes developmental timing. Denying the influence of genetics misrepresents a key factor in growth and development.
D. This statement reflects an accurate understanding of developmental principles. Growth and developmental milestones occur in a predictable sequence (cephalocaudal, proximodistal, and simple-to-complex patterns), but the timing can vary for each child. This acknowledges normal individual differences while recognizing typical developmental patterns.
Correct Answer is D
Explanation
A. Fatigue is a common and expected change in pregnancy due to increased metabolic demands and hormonal shifts. It is not specific for heart failure.
B. Mild dyspnea on exertion is common in pregnancy because of increased oxygen demand and diaphragmatic elevation. This alone does not indicate heart failure.
C. Peripheral edema is a typical physiological change in pregnancy, especially in the lower extremities, due to increased blood volume and venous pressure. It is usually not concerning unless accompanied by other signs.
D. These findings are not typical of normal pregnancy and may indicate fluid overload and impaired cardiac function, suggesting heart failure. Pulmonary congestion can cause dyspnea, persistent cough, and orthopnea, while generalized edema (especially in the face and hands) is concerning for cardiac or severe renal involvement.
