A nurse in a provider’s office is assessing the motor skill development of a 15-month-old toddler during a well-child visit. Which of the following gross motor skills should the nurse expect?
Takes several steps on tiptoes.
Walks without assistance using a wide stance.
Has an accentuated cervical curvature when standing.
Stands with the feet turned slightly inward.
The Correct Answer is B
Choice A rationale
At 15 months, toddlers typically lack the motor coordination required for precise balance needed to walk on tiptoes. This skill usually develops closer to 2-3 years of age.
Choice B rationale
Walking without assistance using a wide stance reflects a 15-month-old's gross motor development, as toddlers at this age begin independent walking with a broad base to enhance stability.
Choice C rationale
An accentuated cervical curvature when standing is not a normal feature of gross motor development at 15 months. Such a curvature is more associated with postural abnormalities or older age.
Choice D rationale
Standing with feet turned slightly inward is not typical at 15 months. Foot alignment is usually neutral; inward alignment could indicate conditions like intoeing, which requires evaluation.

Correct Answer is B
Explanation
Choice A rationale
Monitoring blood pressure trends ensures early detection of medication effectiveness, yet is secondary to addressing critical hypokalemia. Normal blood pressure is 120/80 mmHg; deviations warrant monitoring, but this is not the priority intervention.
Choice B rationale
Administering potassium chloride STAT addresses potential hypokalemia, which risks arrhythmias and muscle weakness. Normal potassium levels range between 3.5-5.0 mEq/L, highlighting urgency when potassium is below normal.
Choice C rationale
Reassessing additional medication needs at a set time ensures comprehensive care but does not address immediate life-threatening conditions like hypokalemia, which requires urgent correction to prevent cardiac dysfunction.
Choice D rationale
Educating about blood pressure maintenance is crucial for long-term management but does not address the immediate physiological imbalance or risk of arrhythmias due to electrolyte disturbance, making it a lower priority.
Correct Answer is A
Explanation
Choice A rationale
Sterile water prevents contamination and maintains the client’s safety during administration, reducing the risk of introducing pathogens. It ensures proper medication dissolution for smooth NG tube flow.
Choice B rationale
Mixing medications together increases the risk of drug interactions, altering pharmacokinetics or pharmacodynamics, potentially causing side effects. It is unsafe for administering via an NG tube without compatibility checks.
Choice C rationale
Sublingual medications are designed for absorption through oral mucosa, bypassing first-pass metabolism. Crushing alters this route, reducing effectiveness. They should not be crushed or administered via NG tube.
Choice D rationale
Flushing with only 5 mL of saline is insufficient to clear residue, risking medication clogging. Standard practice suggests using at least 15-30 mL to ensure patency and avoid tube obstruction.
