Question 1 of 5
The nurse notes the following laboratory test results on a 24-hour post-burn client. Which abnormality should be reported to the physician immediately?
Correct Answer: A
Rationale: Hyperkalemia (7.5 mEq/L) is life-threatening, risking arrhythmias, and requires immediate reporting. Hyponatremia (
B), slightly low pH (
C), and elevated hematocrit (
D) are less urgent in early burn care.
Question 2 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 3 of 5
The nurse is caring for a client who is receiving magnesium sulfate for preeclampsia. Which intervention is most appropriate to prevent toxicity?
Correct Answer: D
Rationale: Magnesium sulfate toxicity can cause respiratory depression loss of reflexes and reduced urine output. Monitoring respiratory rate reflexes and urine output is essential to detect toxicity early and ensure patient safety.
Question 4 of 5
An amniocentesis at 32 weeks gestation reveals that a multigravida with diabetes has an L/S ratio of 1:1 with the presence of phosphatidylglycerol. Based on the amniocentesis,the nurse knows that if delivered now:
Correct Answer: C
Rationale: An L/S ratio of 1:1 at 32 weeks indicates immature fetal lungs increasing the risk of respiratory distress syndrome (RDS) if delivered now. Phosphatidylglycerol presence is positive but does not fully mitigate RDS risk. The other risks are not directly related to the L/S ratio.
Question 5 of 5
A client with a history of liver cirrhosis is admitted with complaints of ascites. The nurse should give priority to:
Correct Answer: A
Rationale: Ascites increases infection risk (e.g., spontaneous bacterial peritonitis) in cirrhosis, so monitoring for infection is the priority.
