Question 1 of 5
Which term describes the play activity of the preschool aged child?
Correct Answer: B
Rationale: Preschool-aged children (3–5 years) typically engage in associative play, where they play together with shared activities but without formal rules or organization. Cooperative play develops later, parallel play is common in toddlers, and solitary play is seen in younger children.
Question 2 of 5
The nurse is caring for a client with a history of sickle cell anemia. Which intervention is most important during a sickle cell crisis?
Correct Answer: A
Rationale: Sickle cell crisis causes vaso-occlusion, reducing tissue oxygenation. Administering oxygen is the priority to prevent hypoxia. Cold packs worsen vasoconstriction, rest is secondary, and antibiotics are for infections.
Question 3 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 4 of 5
The nurse is removing a peripherally inserted central catheter (PICC). The nurse should position the patient in which position?
Correct Answer: D
Rationale: Trendelenburg position (head down) is used when removing a PICC line to reduce the risk of air embolism by increasing venous pressure. Fowler’s, right, or left side-lying positions do not provide this protection.
