Decreasing level of consciousness is a symptom of which of the following physiological phenomena?

Correct Answer: A

Rationale: A decreasing level of consciousness is a symptom often associated with increased intracranial pressure (ICP). When the pressure inside the skull rises, it can compress and damage the brain, leading to a deterioration in consciousness. Common causes of increased ICP include traumatic brain injury, brain tumors, and infections. As ICP continues to rise, it can result in serious consequences such as brain herniation, which can be life-threatening if not promptly managed. Therefore, a decreasing level of consciousness should raise concerns about increased ICP and warrant immediate medical evaluation and intervention.

Correct Answer: C

Rationale: The transmission of HIV has been established through the following body fluids:

Correct Answer: C

Rationale: Normal serum osmolality typically ranges between 280 to 295mOsm/kg. Serum osmolality reflects the concentration of solute particles in the blood, including sodium, glucose, and blood urea nitrogen. Sodium is a major determinant of serum osmolality, but it is not the only factor. In this case, since the patient's serum sodium is within the normal range, the nurse can reasonably estimate that the serum osmolality would fall within the normal range of 280 to 295mOsm/kg. Options A, B, and D are outside the typical range for serum osmolality in a healthy individual.

Correct Answer: D

Rationale: Kawasaki disease is an inflammatory condition that primarily affects medium-sized blood vessels, including the coronary arteries. If not promptly and effectively treated, about 25% of untreated cases can lead to the development of coronary artery aneurysms. These aneurysms can increase the risk of serious complications such as myocardial infarction and sudden death. Therefore, it is crucial to closely monitor and manage the cardiovascular complications in patients with Kawasaki disease, particularly the risk of aneurysm formation.

Correct Answer: C

Rationale: When caring for a client with influenza, immediate recognition of respiratory distress is crucial. Influenza can lead to respiratory complications such as pneumonia, which may result in respiratory distress. Early detection of symptoms such as increased respiratory rate, shortness of breath, and chest pain can help in providing prompt intervention and preventing further complications. Therefore, the nursing intervention involved in caring for a client with influenza is to closely monitor the respiratory status and quickly recognize any signs of respiratory distress. This proactive approach can potentially save the client's life and improve outcomes.
