Question 1 of 5
Following insertion of a nasogastric (NG) tube, the nurse aspirates the gastric contents to check the pH to determine if the NG tube is correctly placed. Which of the following pH values is consistent with gastric secretions?
Correct Answer: D
Rationale: Gastric secretions typically have a pH of 1.5-3.5, so a pH of 4 (
D) is consistent with correct NG tube placement in the stomach. Higher pH values (A, B,
C) suggest placement in the intestines or respiratory tract.
Question 2 of 5
Which finding is the best indication that a client with ineffective airway clearance needs suctioning?

Question 3 of 5
A client with advanced Alzheimer's disease has been prescribed haloperidol (Haldol). What clinical manifestation suggests that the client is experiencing side effects from this medication?

Question 4 of 5
The client has a nitroprusside drip infusing at 0.3 mcg/kg/min. The concentration is 50 mg nitroprusside in 250 mL D5W. The client weighs 70 kg. What will the IV infusion rate be?
Correct Answer: 6.3 mL/hr
Rationale:
To calculate: 0.3 mcg/kg/min × 70 kg = 21 mcg/min. Concentration is 50 mg/250 mL = 200 mcg/mL. Rate = 21 mcg/min ÷ 200 mcg/mL = 0.105 mL/min × 60 min/hr = 6.3 mL/hr.
Question 5 of 5
