Correct Answer: C

Rationale: Rationale for Correct Answer C: Endotracheal suctioning should be done as indicated by patient assessment because not all patients require routine suctioning. Performing unnecessary suctioning can lead to potential complications such as mucosal damage and increased risk of infection. Therefore, the nurse must assess the patient's respiratory status, auscultate lung sounds, monitor oxygen saturation levels, and observe for signs of increased secretions before deciding to perform suctioning. Summary of Incorrect Choices: A: Endotracheal suctioning does not directly impact intracranial pressure. It is primarily focused on maintaining airway patency and removing respiratory secretions. B: While endotracheal suctioning may temporarily suppress the cough reflex during the procedure, its primary purpose is to clear airway secretions to prevent complications such as atelectasis and respiratory distress. D: Saline instillation before suctioning is not recommended as it can lead to negative outcomes such as dehydration, mucosal damage, and increased risk of infection

Correct Answer: C

Rationale: The correct answer is C: Primary nursing. Primary nursing is a care delivery model where one nurse is responsible for the total care of a group of clients over a 24-hour period. This promotes continuity of care, individualized attention, and better nurse-client relationships. In primary nursing, the nurse plans and directs care, coordinates with other healthcare team members, and serves as the main point of contact for the clients. A: Case management involves coordinating care across different healthcare providers and services, not necessarily focusing on a specific group of clients over a 24-hour period. B: Team nursing involves a team of healthcare providers working together to deliver care, rather than one nurse being responsible for a specific group of clients over a 24-hour period. D: Functional nursing divides tasks among different healthcare team members based on their specific skills, which may not provide the same level of continuity and individualized care as primary nursing.

Correct Answer: B

Rationale: The correct answer is B: Cry along with the patient’s family members. This action demonstrates empathy and support for the family's grief, showing that the nurse acknowledges and shares their feelings. It can help the family feel understood and supported during a difficult time. By crying with the family, the nurse can validate their emotions and provide comfort without intruding on their personal space. This approach fosters a sense of connection and trust between the nurse and the family, enhancing the quality of care provided. Incorrect Choices: A: Contact a grief counselor as soon as possible - This choice may be premature and could come across as impersonal or distancing in the immediate aftermath of the patient’s death. C: Leave the home as soon as possible - This choice would be insensitive and could make the family feel abandoned in their time of need. D: Consider whether working in hospice is desirable because patient losses are common - This choice is inappropriate as it suggests the nurse should reconsider their career choice based on emotional reactions,

Correct Answer: C

Rationale: The correct answer is C: intrarenal disease, probably acute tubular necrosis. The patient's symptoms of general malaise, fatigue, decreased urinary output, along with the presence of coarse, muddy brown granular casts and hematuria in the urinalysis indicate kidney damage. Acute tubular necrosis is a common cause of acute kidney injury characterized by damage to the renal tubules, leading to impaired kidney function. The presence of granular casts and hematuria suggests tubular injury and bleeding within the kidney. Choices A and B are incorrect as they refer to prerenal and postrenal causes of kidney injury, respectively, which do not align with the patient's symptoms and urinalysis findings. Choice D is incorrect as a urinary tract infection would typically present with different symptoms and urinalysis findings.

Correct Answer: D

Rationale: The correct answer is D: Assess and intervene for causes of agitation. In a critically ill patient, agitation while intubated could indicate underlying issues like pain, delirium, or inadequate sedation. By assessing and addressing the root cause of agitation, the nurse can improve patient comfort and prevent potential harm from restraints. Removing restraints periodically for skin integrity (B) and range of motion (C) is important but should not be the primary focus when agitation is present. Maintaining restraints (A) without addressing the agitation could lead to increased distress and potential complications.
