Concepts and Cases in Nursing Ethics Test Bank

Correct Answer: C

Rationale: In a client experiencing hypovolemic shock, the priority collaborative intervention is to provide replacement of volume to improve tissue perfusion and restore organ function. Hypovolemic shock is characterized by a significant loss of intravascular volume, leading to inadequate tissue perfusion and oxygenation. Beta-adrenergic blockers can exacerbate hypovolemic shock by further decreasing cardiac output and blood pressure. Therefore, the immediate priority is to address the hypovolemia by providing volume replacement through fluid resuscitation to stabilize the patient before assessing the cause of bleeding or establishing invasive cardiac monitoring. Administering analgesics for pain control is important but not the priority in this situation.

Correct Answer: A

Rationale: A. Initiate oxygen therapy: Providing oxygen therapy is appropriate to ensure adequate oxygenation and tissue perfusion during episodes of paroxysmal supraventricular tachycardia.

Correct Answer: A

Rationale: The priority action for the nurse before initiating discharge teaching with a client with diabetes and a large wound is to assess the client's current knowledge regarding dressing changes. This step is crucial as it helps the nurse to understand the client's baseline understanding and skills related to wound care, which will guide the teaching process effectively. By asking the client to state what they know about the current dressing changes, the nurse can identify any knowledge gaps or misconceptions that need to be addressed. This assessment will ensure that the teaching is tailored to the client's specific needs and promotes successful wound healing and overall diabetes management.

Correct Answer: B

Rationale: Endocarditis is a common complication that individuals with repaired congenital heart defects may still be at risk for. Endocarditis is an infection of the inner lining of the heart chambers and valves. The altered structure of the heart tissue from the previous defect and surgery can create an increased risk for bacterial growth and infection. Patients with a history of congenital heart defects should be monitored for signs and symptoms of endocarditis, such as fever, fatigue, new heart murmurs, and evidence of systemic embolization. Prophylactic antibiotics before certain dental and surgical procedures may be recommended to prevent endocarditis in this population. Therefore, the nurse should be vigilant in monitoring for any symptoms suggestive of endocarditis in this client.

Correct Answer: D

Rationale: Terazosin is an alpha-1 adrenergic receptor blocker. By blocking alpha-1 receptors in the vascular smooth muscle, terazosin causes dilation of both arteries and veins, leading to reduced peripheral vascular resistance and decreased blood pressure. This dilation effect is achieved by preventing the binding of norepinephrine to alpha-1 receptors, thereby inhibiting vasoconstriction. Terazosin is commonly used in the treatment of hypertension to help lower blood pressure by reducing the workload on the heart and improving blood flow to organs and tissues.
