Correct Answer: A

Rationale: The correct answer is hepatitis A. Hepatitis A does not produce a carrier state after its acute phase. It is transmitted via contaminated water or food through the oral-fecal route and is not blood-borne. Hepatitis B, choice B, can lead to a carrier state where the person remains infectious despite being asymptomatic. Hepatitis C, choice C, can also result in a chronic carrier state. Hepatitis D, choice D, is an incomplete virus that requires hepatitis B to replicate; it does not lead to a carrier state on its own.

Correct Answer: D

Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1°F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.

Correct Answer: A

Rationale: The correct action for a client with major head trauma receiving bolus enteral feeding is to measure intake and output (I&O). Enteral feedings are hyperosmotic agents that can cause fluid shifts. Monitoring I&O is crucial to assess fluid balance, ensuring that input matches output. Checking albumin levels (choice B) is important for assessing nutritional status but is not the immediate priority in this situation. Monitoring glucose levels (choice C) is also important but not as critical as measuring I&O in this context. Increasing enteral feeding (choice D) should only be done based on a healthcare provider's order after assessing the patient's condition, not as the most important nursing order at this time.

Correct Answer: D

Rationale: Cirrhosis is the correct answer. In cirrhosis, the liver is unable to detoxify ammonia to urea, leading to an accumulation of ammonia in the blood. This can result in hepatic encephalopathy, a condition characterized by high ammonia levels affecting brain function. Renal failure (Choice A), psoriasis (Choice B), and lupus (Choice C) are not directly associated with an increased risk of high ammonia levels as seen in cirrhosis.

Correct Answer: D

Rationale: The five rights of medication administration are dose, client, drug, route, and time. The correct answer is 'routine' as it is not commonly recognized as one of the essential rights in medication administration. Choice A, client, is necessary to ensure the right medication is administered to the right individual. Choice B, drug, is crucial to confirm the correct medication is given. Choice C, dose, is essential to ensure the right amount of medication is administered. Choice D, routine, is not typically included in the five rights of medication administration and is therefore the correct answer.
