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?

Choice A rationale

Nasal flaring signals increased work of breathing due to airflow resistance or hypoxia, common in dyspnea associated with COPD. It indicates compensatory respiratory effort to maintain oxygenation under compromised airway conditions.

Choice B rationale

A respiratory rate of 16/min falls within the normal range (12 to 20 breaths/min) and doesn't indicate dyspnea. Dyspnea typically involves tachypnea or labored breathing as compensatory mechanisms in COPD.

Choice C rationale

Decreased depth of respirations isn't consistent with dyspnea in COPD, where accessory muscle use typically results in shallow, rapid breathing to maintain ventilation and compensate for airflow limitations.

Choice D rationale

A pulse oximetry reading of 95% is within normal limits (95 to 100%) and doesn't indicate hypoxia. COPD clients often have lower baseline oxygen saturation, and dyspnea is better assessed by clinical signs, not isolated saturation.

Choice A rationale

Smoking causes colorectal mucosal damage, increasing cancer risk. Quitting reduces exposure to carcinogens like polycyclic aromatic hydrocarbons, significantly lowering cancer incidence.

Choice B rationale

Alcohol metabolizes into acetaldehyde, a carcinogenic compound affecting colorectal cells. Reducing consumption minimizes exposure, decreasing risks associated with chronic inflammation and DNA damage.

Choice C rationale

A high-fat diet promotes bile acid secretion in the colon, altering microbiota and increasing cancer-promoting secondary bile acids. Adjusting dietary fat intake reduces this risk.

Choice D rationale

Colorectal polyps are nonmodifiable since they represent preexisting pathologic changes. Their presence signals enhanced risk, necessitating monitoring rather than behavioral modification.
