The most accurate assessment parameters for the nurse to use to determine adequate tissue perfusion in the shock client include

blood pressure, pulse and respirations.

level of consciousness, urine output, skin color and temperature.

breath sounds, blood pressure and body temperature.

pulse pressure, level of consciousness and pupillary response.

Answer and Explanation

The Correct Answer is B

A. Blood pressure, pulse and respirations: Vital signs are important for monitoring overall stability, but they can remain within normal limits in the early stages of shock due to compensatory mechanisms. Relying solely on vital signs may not provide the most accurate assessment of tissue perfusion.

B. Level of consciousness, urine output, skin color and temperature: These parameters directly reflect the adequacy of tissue perfusion. Altered mental status indicates cerebral hypoperfusion, decreased urine output signals renal hypoperfusion, and cool, pale skin reflects peripheral vasoconstriction. They provide an immediate assessment of organ and tissue oxygenation.

C. Breath sounds, blood pressure and body temperature: Breath sounds assess respiratory status, and temperature indicates thermoregulation, but neither provides a direct measure of tissue perfusion. Blood pressure alone may not reflect early perfusion deficits.

D. Pulse pressure, level of consciousness and pupillary response: While level of consciousness is relevant, pulse pressure and pupillary response are less sensitive indicators of tissue perfusion compared to urine output and skin characteristics. These parameters may change later in shock progression.

Correct Answer is D

Explanation

A. The apical pulse rate is 68 beats/minute: While propranolol lowers heart rate by blocking beta-adrenergic receptors, heart rate alone does not directly indicate prevention of variceal bleeding. The primary goal of therapy is to reduce portal hypertension and prevent hemorrhage.

B. Blood pressure is less than 120/80 mmHg: A reduction in blood pressure can occur with propranolol, but systemic blood pressure is not the most direct measure of efficacy in preventing esophageal variceal bleeding. Portal venous pressure reduction is the key therapeutic target.

C. Capillary refill is less than 2 seconds: Capillary refill reflects peripheral perfusion and is not related to the effectiveness of propranolol in controlling portal hypertension or preventing variceal hemorrhage.

D. Stools test negative for occult blood: The absence of occult blood in stools indicates that bleeding from esophageal varices is being prevented. This directly reflects the effectiveness of propranolol in reducing the risk of variceal hemorrhage, which is the primary therapeutic goal.

A. Document and continue to monitor the parameters. B. Decrease the client's IV infusion rate. C. Check the client's pupillary response to light. D. Notify the health care provider about the assessments.

Correct Answer is A

Explanation

A. Document and continue to monitor the parameters: The client’s MAP and ICP values are within acceptable limits. MAP is 72 mmHg, and CPP (MAP − ICP = 72 − 13 = 59 mmHg) is near the lower threshold of adequate cerebral perfusion. Continuous monitoring is appropriate to detect any changes.

B. Decrease the client's IV infusion rate: Reducing IV fluids is unnecessary because blood pressure and cerebral perfusion are currently adequate. Doing so could lower MAP and risk inadequate cerebral perfusion.

C. Check the client's pupillary response to light: Pupillary assessment is important, but it is a routine neurological check. In the absence of new changes in mental status or vital signs, it is not the highest-priority action compared to ongoing monitoring of current parameters.

D. Notify the health care provider about the assessments: There is no urgent abnormality in the blood pressure or ICP at this time. Immediate notification is not required unless trends show deterioration.
