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: A

Rationale: Caffeine is a diuretic, which means it increases urine production by promoting the excretion of water from the body through the kidneys. Therefore, substances like caffeine-containing drinks, such as coffee and cola, can lead to an increase in the amount of urine produced.

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: C

Rationale: Renal failure often necessitates fluid restriction to prevent fluid overload. In renal failure, the kidneys are unable to effectively filter and excrete excess fluids, leading to fluid accumulation in the body. Restricting fluid intake helps manage this condition by preventing further fluid buildup and complications such as edema and electrolyte imbalances.
