A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?

Calcium.

Potassium.

Phosphate.

pH.

Answer and Explanation

The Correct Answer is C

Choice A reason: Calcium acetate is used to bind phosphate in the gastrointestinal tract to reduce phosphate absorption, which is often elevated in clients with CKD. A decrease in serum calcium is not the intended effect of this medication.

Choice B reason: Potassium levels are not directly affected by calcium acetate. This medication specifically targets phosphate binding.

Choice C reason: A decrease in phosphate levels indicates that calcium acetate is effectively binding phosphate and reducing its absorption from the diet. This is the desired effect, as elevated phosphate levels can lead to complications in CKD.

Choice D reason: The pH of the blood is not directly influenced by calcium acetate. The primary purpose of this medication is to manage phosphate levels, not to alter blood pH.

Correct Answer is A

Explanation

Choice A reason: Insomnia can be a common and temporary side effect when starting rivastigmine. Educating the caregiver about this potential side effect helps them understand that it may resolve over time and reassures them about the safety of the medication.

Choice B reason: Advising that the purpose of the medication is to promote sleep is incorrect. Rivastigmine is used to improve cognitive function in Alzheimer's disease, not specifically to promote sleep.

Choice C reason: Instructing the caregiver to withhold the medication without consulting the healthcare provider is not advisable. Adjusting or discontinuing medication should always be done under medical supervision.

Choice D reason: Notifying the healthcare provider about increasing the dosage for insomnia is inappropriate. The focus should be on managing the side effect without altering the intended therapeutic effect of the medication.

A. Instruct the client to take the two medications at least two hours apart. B. Advise the client that the birth control pills will be less effective while taking doxycycline hyclate. C. Encourage the client to stop taking birth control pills until she has finished taking all the doxycycline hyclate. D. Notify the healthcare provider of the contraindication to tetracyclines.

Correct Answer is B

Explanation

Choice A reason: Instructing the client to take the medications two hours apart does not prevent the interaction that reduces the effectiveness of birth control pills when taken with doxycycline.

Choice B reason: It is important to advise the client that doxycycline can reduce the effectiveness of birth control pills. The client should be encouraged to use additional forms of contraception to prevent unintended pregnancy.

Choice C reason: Stopping birth control pills is not necessary; instead, the client should be informed about the interaction and the need for additional contraception.

Choice D reason: While notifying the healthcare provider of potential contraindications is good practice, it does not provide immediate guidance to the client on how to manage the interaction between doxycycline and birth control pills.
