The nurse is evaluating care provided to a new mother whose infant is at risk for sudden infant death syndrome (SIDS). Which statement by the mother indicates teaching has been effective?

Correct Answer: B

Rationale: Planning to quit smoking (B) indicates effective teaching, as smoking cessation reduces SIDS risk.

Correct Answer: C

Rationale: Chest physiotherapy may help loosen and mobilize secretions, increasing mucus clearance. This is especially helpful for patients with large amounts of secretions or an ineffective cough, such as patients with cystic fibrosis. Chest physiotherapy has limited evidence for its effectiveness and is not recommended for use in numerous patient populations, including children with pneumonia, adults with COPD, and postoperative adults (Andrews et al., 2013; Lisy, 2014; Strickland et al., 2013).

Correct Answer: C

Rationale: Steam inhalation aims to loosen mucus (mucolytic), relieve congestion, and moisten airways, but it is typically administered for 10-15 minutes, not 60 minutes, making this the exception.

Correct Answer: D

Rationale: Protein digestion starts in the stomach with pepsin, and fat digestion begins there with gastric lipase, though it's minimal.

Correct Answer: D

Rationale: Vitamin D deficiency causes rickets by impairing calcium absorption, leading to weak bones.
