What is the primary goal of nursing care for the patient who is diagnosed with any type of shock? To manage and treat:

increased cardiac output.

inadequate tissue perfusion.

fluid overload or deficit

vasoconstriction of vasculature.

Answer and Explanation

The Correct Answer is B

A) Increased cardiac output:
While cardiac output is an important factor in shock management, the primary goal of nursing care is not specifically to increase cardiac output. Shock typically involves inadequate tissue perfusion, which may be caused by a variety of factors including low cardiac output, vasodilation, or fluid imbalance. The focus of nursing care is to restore adequate perfusion to tissues, which may involve improving cardiac output as part of a larger therapeutic strategy.

B) Inadequate tissue perfusion:
The primary goal in the treatment of shock is to restore adequate tissue perfusion, as shock is defined by a failure of the circulatory system to supply sufficient oxygen and nutrients to the body's tissues and organs. Inadequate tissue perfusion can lead to organ dysfunction and, if not addressed, can result in organ failure and death. Nursing interventions are aimed at improving perfusion through fluid resuscitation, vasoactive medications, and other strategies to ensure that oxygen and nutrients are delivered to vital organs.

C) Fluid overload or deficit:
Managing fluid status is crucial in shock, as fluid imbalance (either overload or deficit) can exacerbate the condition. However, fluid overload or deficit is not the primary focus; rather, it is one aspect of managing inadequate tissue perfusion. For example, in hypovolemic shock, the nurse would manage fluid deficit, while in cardiogenic shock, the focus would be on optimizing fluid balance without causing overload.

D) Vasoconstriction of vasculature:
While vasoconstriction can be a compensatory mechanism in certain types of shock (e.g., hypovolemic shock), the primary goal is not to induce vasoconstriction per se. In some cases, vasodilation may occur (as in septic shock), and vasoconstriction could be harmful. The goal is to optimize the vascular tone and perfusion, which may involve vasodilation or vasoconstriction depending on the type of shock.

Correct Answer is B

Explanation

A) Establish IV access, apply 2L O2 via nasal cannula, and notify provider:
While establishing IV access and providing oxygen are important aspects of managing many emergencies, this patient's symptoms suggest the presence of autonomic dysreflexia rather than a primary respiratory or circulatory issue. In autonomic dysreflexia, the primary concern is to remove the noxious stimulus (such as a full bladder, bowel impaction, or tight clothing) that is causing the severe hypertension and bradycardia.

B) Assess below injury for noxious stimuli, anticipate order for hypertensive medication:
The patient’s symptoms are consistent with autonomic dysreflexia, a serious condition that occurs in individuals with a spinal cord injury at or above the T6 level. The body’s autonomic nervous system overreacts to noxious stimuli (such as a distended bladder, bowel impaction, or skin irritation) below the level of injury, leading to a severe hypertensive crisis, bradycardia, and sympathetic hyperactivity. The nurse should immediately assess for and relieve any noxious stimuli below the injury level (e.g., checking for a full bladder, constipation, or tight clothing) and anticipate an order for antihypertensive medications if the blood pressure remains elevated.

C) Administer acetaminophen and initiate intravenous (IV) fluids, anticipate order for atropine:
While pain and discomfort (which can exacerbate autonomic dysreflexia) may need to be managed, acetaminophen is not the priority in this case. The priority is addressing the underlying cause of autonomic dysreflexia, such as relieving noxious stimuli. Additionally, atropine is used for bradycardia, but in autonomic dysreflexia, the bradycardia is secondary to the hypertensive crisis and usually resolves once the noxious stimulus is removed.

D) Lower the head of the bed and apply a cool compress to the forehead:
Although lowering the head of the bed may help reduce intracranial pressure and applying a cool compress may provide comfort, these interventions do not address the underlying cause of the autonomic dysreflexia.

A. respiratory acidosis B. metabolic acidosis C. metabolic alkalosis D. respiratory alkalosis

Correct Answer is D

Explanation

A) Respiratory acidosis:
Respiratory acidosis occurs when there is an accumulation of carbon dioxide (CO2) in the blood, leading to a decrease in pH. In the given blood gas values, the PaCO2 is 28 mmHg, which is lower than the normal range (35-45 mmHg), indicating that CO2 is being exhaled more than usual, not accumulating.

B) Metabolic acidosis:
Metabolic acidosis results from a decrease in bicarbonate (HCO3-) or an increase in acid in the body. However, in the provided values, the bicarbonate (HCO3-) is normal at 24 mEq/L, and the pH is elevated at 7.51, indicating alkalosis rather than acidosis

C) Metabolic alkalosis:
Metabolic alkalosis occurs when there is an increase in bicarbonate levels or excessive loss of acids, often associated with vomiting or diuretic use. However, in this case, the bicarbonate level (HCO3-) is normal, and the pH is more consistent with alkalosis due to respiratory factors, not metabolic causes.

D) Respiratory alkalosis:
Respiratory alkalosis occurs when there is excessive exhalation of CO2, leading to a rise in blood pH (alkalosis). The pH is 7.51, which is above the normal range (7.35-7.45), indicating alkalosis. Additionally, the PaCO2 is low at 28 mmHg, which suggests that the client is hyperventilating and exhaling too much CO2, confirming respiratory alkalosis as the correct interpretation.
