Question 1 of 5
The nurse would need to monitor the serum glucose levels of a client receiving which of the following medications, owing to its effects on glycogenolysis and insulin release?
Correct Answer: D
Rationale: Norepinephrine's side effects are primarily related to safe, effective care environment and include decreased peripheral perfusion and bradycardia. Dobutamine's side effects include increased heart rate and blood pressure, ventricular ectopy, nausea, and headache. Propranolol's side effects include elevated blood urea nitrogen, serum transaminase, alkaline phosphatase, and lactic dehydrogenase. Epinephrine increases serum glucose levels by increasing glycogenolysis and inhibiting insulin release. Prolonged use can elevate serum lactate levels, leading to metabolic acidosis, increased urinary catecholamines, false elevation of blood urea nitrogen, and decreased coagulation time.
Question 2 of 5
A 19-year-old male client arrived via ambulance to the emergency room following a motorcycle accident. He is comatose. His face has evidence of dried blood. On assessment, the nurse notes an obvious injury to his left eye. The preferred positioning for a client with an obvious eye injury is:
Correct Answer: D
Rationale: A reclining position can cause a penetrating object to advance further into the eye. Prevention of further injury is the priority, not comfort. A side-lying position may increase intraocular and intracranial pressure if an accompanying head injury is suspected. A sitting position with the head supported will prevent further injury while allowing injury care to take place.
Question 3 of 5
The nurse is assessing a client with suspected anaphylactic shock. Which intervention is the priority?
Correct Answer: A
Rationale: Epinephrine is the priority in anaphylactic shock to reverse bronchoconstriction and hypotension. IV fluids and oxygen are secondary, and Trendelenburg is not recommended.
Question 4 of 5
A client with a history of a stroke is being taught to use a cane. The nurse should teach the client to:
Correct Answer: C
Rationale: The cane should be used on the weak side to support the affected leg, improving balance and gait post-stroke. Holding it in the strong hand or advancing with the strong leg is incorrect.
Question 5 of 5
The nurse is caring for a client with a history of schizophrenia. The nurse should expect the client to have:
Correct Answer: A
Rationale: Schizophrenia is characterized by hallucinations, delusions, and disorganized thinking, with hallucinations being a common symptom.
