NCLEX Style Questions on Oxygenation Questions
Question 1 of 5

Question 3 of 5
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.)
Question 4 of 5
Which of the following is the initial sign of hypoxemia in an adult client? 1. Tachypnea 2. Tachycardia 3. Cyanosis 4. Pallor 5. Irritability 6. Flaring of Nares
Correct Answer: B
Rationale: Tachycardia (2) and irritability (5) are early signs of hypoxemia as the body compensates for low oxygen before later signs like cyanosis or flaring nares appear.
Question 5 of 5
Enzyme secreted by the small intestine after it detects a bolus of fatty food. This will contract the gallbladder to secrete bile and relax the sphincter of Oddi to aid in the emulsification of fats and its digestion.
Correct Answer: C
Rationale: Cholecystokinin (CCK) triggers gallbladder contraction and bile release for fat emulsification and digestion.
