Question 1 of 5
The nurse is preparing to administer a feeding via a nasogastric tube. The nurse would perform which of the following before initiating the feeding?
Correct Answer: A
Rationale: Verifying nasogastric tube placement by aspirating stomach contents (and checking pH) is critical to prevent aspiration. Left-lying position is incorrect, 50% dextrose is inappropriate, and microwaving can cause burns or nutrient degradation.
Question 2 of 5
Stat serum electrolytes ordered for a client in acute renal failure revealed a serum potassium level of 6.4. The physician is immediately notified and orders 50 mL of dextrose and 10 U of regular insulin IV push. The nurse administering these drugs knows the rationale for this therapy is to:
Correct Answer: D
Rationale: Sodium polystyrene sulfonate (Kayexalate), a cation exchange resin, exchanges sodium ions for potassium ions in the large intestine reducing the serum potassium. Calcium is administered to protect the myocardium from the adverse effects of hyperkalemia. Serum levels reflect hyperkalemia. Rapid catabolism releases potassium from the body tissue into the bloodstream. Infection and hyperthermia increase the process of catabolism. The administration of dextrose and regular insulin IV forces potassium back into the cells decreasing the potassium in the serum.
Question 3 of 5
A behavior-modification program has been started for an adolescent with oppositional defiant disorder. Which statement describes the use of behavior modification?
Correct Answer: C
Rationale: Behavior modification for oppositional defiant disorder often uses a token economy system, where positive behaviors are reinforced with rewards to encourage compliance.
Question 4 of 5
On a home visit, the nurse finds four young children alone. The youngest of the children has bruises on the face and back and circular burns on the inner aspect of the right forearm. The nurse should:
Correct Answer: A
Rationale: Bruises and circular burns suggest abuse, requiring mandatory reporting to child welfare services for investigation and protection. Transporting or staying is secondary to reporting.
Question 5 of 5
The nurse is caring for a client with a history of a stroke who has expressive aphasia. The nurse should:
Correct Answer: C
Rationale: Expressive aphasia impairs speech production. A whiteboard facilitates communication. Simple sentences help, but writing aids are critical, and loud speech or limiting interaction is unhelpful.
