Correct Answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm�. A WBC count of 25,000/mm�, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

Correct Answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8�F (37.7�C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

Correct Answer: A

Rationale: When a healthcare provider administers treatment, such as an injection, against a patient's refusal or will, it constitutes assault and battery. Assault refers to the intentional act that causes a person to fear that they will be touched without consent, while battery involves the actual harmful or offensive contact. In this scenario, administering the injection without the patient's consent is both an assault (causing fear of unwanted contact) and a battery (unwanted physical contact). Therefore, the correct answer is 'Assault and battery.' Negligence refers to a failure to exercise the appropriate level of care expected in a situation, while malpractice involves professional negligence or misconduct.

Correct Answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

Correct Answer: B

Rationale: A positive guaiac test is used to detect the presence of occult (hidden) blood in the stool, suggesting bleeding from the gastrointestinal tract. It is a rapid screening test that can provide immediate information to the healthcare provider about possible gastrointestinal bleeding in patients presenting with symptoms such as nausea, vomiting, diarrhea, and severe abdominal pain.
