What are the key signs of increased intracranial pressure (ICP) that a nurse should monitor for?

Correct Answer: A

Rationale: The correct answer is A: 'Monitor for changes in the level of consciousness.' Key signs of increased intracranial pressure (ICP) include changes in the level of consciousness and pupil dilation. Assessing for bradycardia and monitoring for vomiting are not typically considered primary signs of increased ICP. While bradycardia and vomiting can occur with increased ICP, they are not as specific or sensitive as changes in consciousness and pupil dilation.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.

Correct Answer: A

Rationale: Ethics is the correct answer because it specifically deals with the study of conduct and character. Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. While justice and morals are related to ethical considerations, they do not directly represent the study of conduct and character. Non-maleficence is a principle in medical ethics related to avoiding harm.

Correct Answer: D

Rationale: The correct answer is D because having family members wear a gown and gloves when visiting a client with Clostridium difficile is essential to prevent the spread of infection. Options A, B, and C are incorrect. Negative air-flow systems are not necessary for preventing the spread of C. difficile. While alcohol-based hand sanitizers are effective for routine hand hygiene, they may not be sufficient for C. difficile. Cleaning contaminated surfaces with a phenol solution is not the most effective method for preventing the spread of C. difficile, as spores can be resistant to many disinfectants.
