Question 1 of 5
A nurse is preparing to administer an injection of an opioid medication to a client. The nurse draws out 1 ml of the medication from a 2 ml vial. Which of the following actions should the nurse take?

Question 2 of 5
A client with a feeding tube has developed constipation as a result of inactivity. Which nursing intervention would most likely help to resolve this complication?
Correct Answer: B
Rationale: Constipation due to inactivity is best addressed by increasing dietary fiber and fluid intake, which promote peristalsis and soften stool, even in clients with feeding tubes (via enteral formulas with fiber or additional water flushes). Securing the tube (A) prevents dislodgement but doesn’t address constipation. Monitoring blood glucose (C) is unrelated to bowel elimination. Checking residuals (D) ensures tolerance to feedings but doesn’t directly resolve constipation.

Question 4 of 5
A nurse is teaching staff about the conduction of the heart. In which order will the nurse present the conduction cycle, starting with the initial impulse? Bundle of His, Purkinje network, Intraventricular pathways, Sinoatrial (SA) node, Atrioventricular (AV) node
Correct Answer: B
Rationale: The cardiac conduction cycle starts at the sinoatrial (SA) node (4), the heart’s pacemaker, generating the impulse. It travels to the atrioventricular (AV) node (5), then to the Bundle of His (1), through the intraventricular pathways (3), and finally to the Purkinje network (2) for ventricular contraction. The correct sequence is 4, 5, 3, 1,
