The practical nurse (PN) is caring for an older client who is receiving chemotherapy for lung cancer. Which finding is the highest priority for the PN to report to the charge nurse?
Reference ranges:
- Blood urea nitrogen (BUN): [Adult: 10 to 20 mg/dL or 3.6 to 7.1 mmol/L]
- Platelets: [150,000 to 400,000/mm3 or 150 to 400 x 10^9/L]
Periodic nausea and vomiting
Decreased deep tendon reflexes
Platelet count 135,000/mm3 or 135 x 10^9/L
Blood urea nitrogen 75 mg/dL or 12.9 mmol/L
The Correct Answer is D
A high blood urea nitrogen (BUN) level indicates impaired renal function, which can be caused by dehydration, infection, or nephrotoxic drugs. Chemotherapy can damage the kidneys and increase the risk of renal failure. The PN should report this finding to the charge nurse, as it may require fluid replacement, dose adjustment, or discontinuation of the chemotherapy.
The other options are not correct because:
- Periodic nausea and vomiting are common side effects of chemotherapy that can be managed with antiemetics, hydration, and dietary modifications. They are not as urgent as a high BUN level.
- Decreased deep tendon reflexes may indicate hypocalcemia, hypomagnesemia, or peripheral neuropathy, which can be caused by chemotherapy or other factors. They are not as urgent as a high BUN level.
- A platelet count of 135,000/mm3 or 135 x 10^9/L is slightly below the normal range, but not significantly low. Chemotherapy can cause thrombocytopenia, which increases the risk of bleeding. The PN should monitor the client for signs of bleeding, but this finding is not as urgent as a high BUN level.

Correct Answer is A
Explanation
This finding requires immediate action, as it indicates that the client is not receiving the prescribed amount of oxygen, which can compromise the oxygenation and perfusion of the tissues. The PN should adjust the flowmeter to deliver 3 liters per minute of oxygen, and check for any leaks or kinks in the tubing.
The other options are not correct because:
B. The absence of a humidifier does not require immediate action, as it is not a critical component of the oxygen delivery system. A humidifier can help moisten the dry oxygen and prevent mucosal irritation, but it is not essential for oxygenation.
C. The supine position does not require immediate action, as it is not a contraindication for oxygen therapy. The client may prefer this position for comfort or rest, and it does not affect the oxygen delivery or uptake.
D. The snug fit of the cannula does not require immediate action, as it is not a problem for oxygen therapy. The cannula should fit snugly against the client's cheeks to prevent dislodgment or slippage, and it does not interfere with the oxygen flow or diffusion.
Correct Answer is C
Explanation
Croup is a respiratory infection that causes inflammation and narrowing of the airway, resulting in a barking cough, hoarseness, and stridor. The PN should monitor the child's oxygen saturation level via pulse oximetry, as it can indicate the severity of the airway obstruction and the need for supplemental oxygen or other interventions.
