Which of the following drugs is administered to promote hemostasis and control active bleeding in esophageal varices?
Lactulose
Vasopressin
Propranolol
Neomycin sulfate
The Correct Answer is B
A. Lactulose: Lactulose is used to reduce ammonia levels in hepatic encephalopathy by promoting bowel excretion of nitrogen, but it does not control bleeding. It addresses neurologic complications rather than hemorrhage.
B. Vasopressin: Vasopressin is a potent vasoconstrictor that reduces portal venous pressure, helping control active bleeding from esophageal varices. It is commonly administered in acute variceal hemorrhage to achieve hemostasis and stabilize the client.
C. Propranolol: Propranolol, a nonselective beta-blocker, is used prophylactically to reduce portal hypertension and prevent variceal bleeding. It is not effective in stopping active hemorrhage.
D. Neomycin sulfate: Neomycin is an antibiotic used to reduce intestinal bacteria and lower ammonia levels in hepatic encephalopathy. It has no role in controlling acute variceal bleeding.

Correct Answer is B
Explanation
A. Document and continue to monitor the parameters: While ongoing monitoring is important, the combination of hypotension and ICP of 15 mmHg may compromise cerebral perfusion. Immediate reporting is necessary rather than passive observation.
B. Notify the health care provider about the assessments: Hypotension in a client with a head injury can reduce cerebral perfusion pressure and worsen brain injury. ICP of 15 mmHg is at the upper limit of normal. Promptly notifying the provider ensures timely interventions to optimize perfusion and prevent secondary brain injury.
C. Decrease the client's IV infusion rate: Reducing IV fluids could exacerbate hypotension and further compromise cerebral perfusion. Volume support may be necessary to maintain adequate blood pressure in a head-injured client.
D. Check the client's pupillary response to light: Assessing pupillary response is part of neurologic monitoring, but it does not address the immediate concern of low blood pressure affecting cerebral perfusion. Action should focus on hemodynamic stability first.
Correct Answer is A
Explanation
A. Assess the client's vital signs to establish baselines: Obtaining baseline vital signs is essential before transfusion to detect any changes that may indicate a reaction. Comparing pre- and post-transfusion measurements helps identify fever, hypotension, or tachycardia early. This assessment is a standard safety measure to monitor for adverse events.
B. Ensure that the client has granted verbal consent for transfusion: While informed consent is required, it must already be documented, not just verbal. The nurse verifies consent, but this is not the immediate clinical action needed just prior to starting the transfusion. Documentation of consent ensures legal and ethical compliance.
C. Have the client identify the blood type in writing: Blood type verification is performed by comparing the blood product with the client’s medical record and wristband, not by having the client write it. Client identification is essential, but written self-report is not reliable for safety checks. Correct matching is confirmed by the healthcare team.
D. Facilitate insertion of a central venous catheter for rapid infusion: Central line placement is not required for routine PRBC transfusion unless rapid or large-volume resuscitation is anticipated. Most transfusions are safely administered via peripheral IV.
