1. A newly graduated nurse is admitting a patient with a long history of emphysema. The new nurses preceptor is going over the patients past lab reports with the new nurse. The nurse takes note that the patients PaCO2 has been between 56 and 64 mm Hg for several months. The preceptor asks the new nurse why they will be cautious administering oxygen. What is the new nurses best response?

A. The patients calcium will rise dramatically due to pituitary stimulation.
B. Oxygen will increase the patients intracranial pressure and create confusion.
C. Oxygen may cause the patient to hyperventilate and become acidotic.
D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Correct answer: D

Rationale:

2. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

A. Administer topical lidocaine to the site.
B. Place warm compresses on the site.
C. . Administer prescribed oral pain medication.
D. Massage the site with scented oils.

Rationale:

3. You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?

A. Increased serum sodium
B. Decreased serum potassium
C. Decreased hemoglobin
D. Increased platelets

Correct answer: A

Rationale:

4. You are caring for a patient with a secondary diagnosis of hypermagnesemia. What assessment finding would be most consistent with this diagnosis?

A. Hypertension
B. Kussmaul respirations
C. Increased DTRs
D. Shallow respirations

Correct answer: D

Rationale:

5. Which organ has the greatest effect on fluid output?

A. Kidneys
B. Lungs
C. Skin
D. Intestines

Correct answer: A

Rationale: The correct answer is the kidneys. The kidneys are primarily responsible for regulating fluid balance by filtering blood and adjusting the volume and concentration of urine. The lungs primarily regulate gas exchange, not fluid balance. The skin plays a role in temperature regulation and protection but is not the primary organ for fluid output. The intestines are mainly involved in the absorption of nutrients and water, rather than fluid output.
