PN NCLEX Practice Questions Questions
Extract:
Question 1 of 5
Which oxygen delivery system would the nurse apply that would provide the highest concentrations of oxygen to the client?
Correct Answer: C
Rationale: Non-rebreather mask. The non-rebreather mask has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent inhalation of room air but to allow exhalation of air. When a tight seal is achieved around the mask up to 100% of the oxygen is available.
Question 2 of 5
A client with diabetes phones the clinic stating, 'I have a terrible cold and I don't know what to do about taking my insulin.' Which of the following should be included in the nurse's teaching regarding the client's insulin needs?
Correct Answer: C
Rationale: Infections increase insulin resistance, raising insulin needs. Frequent glucose and ketone monitoring ensures proper management. Withholding insulin or relying on urine tests is dangerous, and infections do alter insulin requirements.

Correct Answer: A
Rationale: Age, obesity, smoking, and family history of hypertension confer the highest risk, as seen in the 63-year-old Caucasian female.
Question 4 of 5
