Which assessments and interventions should the nurse consider when performing tracheal suctioning? Select one that doesn't apply.

Correct Answer: C

Rationale: Close assessment of the patient before, during, and after the procedure is necessary to limit negative effects. Risks include hypoxia, infection, tracheal tissue damage, dysrhythmias, and atelectasis. The nurse should hyperoxygenate the patient before and after suctioning and limit the application of suction to 10 to 20 seconds. The nurse should also take the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Using an appropriate suction pressure (80 to 150 mm Hg) will help prevent atelectasis related to the use of high negative pressure. (Note: E is 'Use an appropriate suction pressure (80 to 150 mm Hg)' from the provided options.)

Correct Answer: C

Rationale: Cholecystokinin (CCK) triggers gallbladder contraction and bile release for fat emulsification and digestion.

Correct Answer: C

Rationale: For 5'2 (62 inches) and 130 lbs, BMI = (130 ×703) / (62²) = 23.8, which falls in the normal range (18.5-24.9).

Correct Answer: D

Rationale: Checking tube placement is critical before feeding to ensure it's in the stomach, preventing aspiration.

Correct Answer: B

Rationale: HFNC provides high flow rates that can wash out dead space and allow precise FiO₂ control, making it a key consideration in its use, unlike the other options which are incorrect or less relevant.
