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: B

Rationale: The brown pigmentation of the lower extremities in clients with venous stasis is primarily caused by the breakdown of red blood cells in the congested tissues. When there is venous stasis, the blood circulation is impaired, leading to a backup of blood in the lower extremities. This stagnant blood contains hemosiderin, a byproduct of red blood cell breakdown. Over time, the hemosiderin deposits in the tissues, causing the characteristic brown discoloration seen in conditions such as chronic venous insufficiency. This process is known as hemosiderin deposition and is a common consequence of venous stasis.

Correct Answer: A

Rationale: The statement "You'll give us written instructions before we go home, correct?" reflects the mother's readiness to learn. This statement shows that the mother is actively seeking out resources and tools to help her understand and remember the instructions for giving her premature baby a bath. It indicates that she is willing to take responsibility for her baby's care and is thinking ahead to ensure she has the necessary information for when she is on her own at home. This statement demonstrates engagement and a proactive approach to learning, which are essential for successfully caring for a premature baby in a NICU setting.

Correct Answer: C

Rationale: A urine output of 200 mL in 8 hours is considered low, especially for a client with cardiomyopathy who is receiving diuretic therapy. This could indicate inadequate cardiac output or worsening heart failure. It is crucial for the nurse to notify the healthcare provider promptly so that appropriate interventions can be initiated to address the underlying cause and prevent further complications. Waiting for improvement without taking action could lead to deterioration in the client's condition.

Correct Answer: B

Rationale: After a stroke, sensory-perceptual changes such as impaired proprioception, altered sensation, and decreased awareness of the affected side can increase the client's risk for injury. These changes can result in difficulties with balance, coordination, and spatial awareness, making the individual more prone to falls and accidents. It is important to implement safety measures and interventions to minimize the risk of injury in these clients, such as providing a structured environment, using assistive devices, and encouraging regular monitoring and assistance as needed.
