Question 1 of 5
The nurse is reviewing discharge teaching with the parent of a pediatric client who has a new tracheostomy. Which of the following statements by the parent would indicate a correct understanding of the teaching?
Correct Answer: D
Rationale: Carrying two tracheostomy tubes (same and smaller size) is correct for emergency preparedness. Immediate tube changes, frequent deep suctioning, or removing humidifiers can worsen the situation or are unsafe.
Question 2 of 5
The nurse is screening clients for those at risk of developing syndrome of inappropriate antidiuretic hormone (SIADH). The nurse should recognize that the client at highest risk for developing SIADH is a client with
Correct Answer: B
Rationale: Small cell lung cancer is strongly associated with SIADH due to ectopic ADH production. Other conditions listed are not significant risk factors.

Sliding-Scale Blood Glucose Levels Regular Insulin Dose
<150 mg/dL (<8.3 mmol/L) 0 units
150-199 mg/dL (8.3-11.0 mmol/L) 3 units
200-249 mg/dL (11.1-13.8 mmol/L) 6 units
250-299 mg/dL (13.9-16.6 mmol/L) 9 units
300-349 mg/dL (16.7-19.4 mmol/L) 12 units
>350 mg/dL (>19.4 mmol/L) 15 units and notify the health care provider
Question 5 of 5
A client with type 1 diabetes has a prescription for 20 units of NPH insulin daily at 7:30 AM and regular insulin before meals, based on a sliding scale. At 7:00 AM, the client's blood glucose level is 220 mg/dL (12.2 mmol/L), and the client's breakfast tray has arrived. What action should the nurse take?
Correct Answer: D
Rationale: Regular insulin is drawn up first to prevent NPH contamination, and both can be mixed in one syringe for a blood glucose of 220 mg/dL, assuming a sliding scale of 6 units. Administering after the meal or using separate injections is incorrect.
