A client with constipation has been prescribed mineral oil. Which of the following reasons should the nurse provide for instructing the client to take the medication between meals or at bedtime?
A) It causes sedation
B) It enhances absorption of the drug
C) It interferes with vitamin absorption
D) It causes nausea and vomiting
C
Feedback:
When mineral oil is taken orally, it interferes with absorption of the fat-soluble vitamins, namely A, D, E, and K. Therefore, it should be given in between meals or at bedtime to avoid interfering with food absorption. Mineral oil does not have a sedative effect. Administering it between meals does not enhance its absorption. Mineral oil is not absorbed; rather, it forms a coating on the feces, acts as a lubricant, softens feces, and prevents straining on bowel movements. It does not cause nausea and vomiting.
