A nurse is caring for a client who has a prescription for lactated Ringer's IV 4,080 mL/24 hr. The nurse should set the IV infusion pump to deliver how many mL/hr to administer half the total volume in the first 8 hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Correct. Measuring gastric residual volumes every 4 hours is important to assess gastric emptying and to determine if the client can tolerate the feedings. If residuals are high, it may indicate delayed gastric emptying and the need to adjust the feeding rate.

B. Incorrect. While flushing the NG tube before and after medications is important to maintain patency, it is typically done with sterile water, not sodium chloride, unless otherwise specified by a protocol. Therefore, this statement may not be fully accurate.

C. Incorrect. The head of the bed should be elevated to a 30-45° angle to help prevent aspiration during enteral feedings.

D. Incorrect. The rate of the feeding should be advanced gradually to prevent overloading the client's gastrointestinal tract. This does not involve advancing the rate every 2 hours.

Choice A rationale:

Headache is a common adverse effect of disulfiram when alcohol is consumed. It is part of the adverse reaction created by the drug to deter individuals from drinking. While headache is a known symptom, tinnitus is a more specific and distinctive adverse effect associated with disulfiram use.

Choice B rationale:

Hypertension is not a common adverse effect of disulfiram. Disulfiram does not directly impact blood pressure. Its primary action is to cause an adverse reaction when alcohol is consumed.

Choice C rationale:

Tinnitus (ringing in the ears) is a known adverse effect of disulfiram when alcohol is ingested. Disulfiram inhibits the breakdown of acetaldehyde, leading to an accumulation of this toxic substance in the body. Tinnitus is one of the symptoms of this toxic reaction and is a significant concern in individuals taking disulfiram for alcohol use disorder.

Choice D rationale:

Insomnia is not a common adverse effect of disulfiram. Disulfiram works by creating an unpleasant reaction when alcohol is consumed, which deters individuals from drinking. This reaction does not typically manifest as insomnia.
