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?

Potassium.

Calcium.

Phosphate.

pH.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Calcium acetate is not used to lower potassium levels. Potassium levels in the blood are typically managed through dietary restrictions, medications like potassium binders, and dialysis in patients with CKD. The normal range for blood potassium levels is 3.5 to 5.2 mEq/L for adults.

Choice B reason:

Calcium acetate can increase calcium levels in the blood, not decrease them. It is important to monitor calcium levels to avoid hypercalcemia, which can lead to complications such as vascular calcification and cardiac issues. The normal range for blood calcium levels is 8.6 to 10.2 mg/dL.

Choice C reason:

Calcium acetate is used to lower phosphate levels in patients with CKD. It works by binding to dietary phosphate in the intestines, forming insoluble calcium phosphate that is excreted in the stool. This helps prevent hyperphosphatemia, a common issue in CKD patients. The normal range for blood phosphate levels is 2.5 to 4.5 mg/dL.

Choice D reason:

Calcium acetate does not directly affect blood pH levels. Blood pH is regulated by the kidneys and lungs, and the normal range is 7.35 to 7.45. While CKD can affect acid-base balance, calcium acetate’s primary role is to manage phosphate levels.

Correct Answer is A

Explanation

Choice A reason: Bupropion is known to cause side effects such as insomnia and weight loss. These side effects are due to its stimulant properties, which can interfere with sleep patterns and suppress appetite1. Patients should be informed about these potential side effects so they can monitor their symptoms and seek medical advice if necessary.

Choice B reason: While changes in taste can occur with some medications, it is not a common side effect of bupropion. Therefore, it is not necessary to specifically instruct patients to notify their healthcare provider about changes in taste when taking bupropion.

Choice C reason: There is no specific requirement to administer bupropion with 8 ounces of water. Bupropion can be taken with or without food, and the amount of water consumed with the medication does not impact its effectiveness.

Choice D reason: Consuming tyramine-free foods is crucial for patients taking monoamine oxidase inhibitors (MAOIs) due to the risk of hypertensive crisis. However, bupropion is not an MAOI, so this dietary restriction is not applicable.

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

Correct Answer is B

Explanation

Choice A Reason:

Notifying the healthcare provider of the contraindication to tetracyclines is not necessary in this context. Doxycycline, a type of tetracycline, is commonly prescribed and does not have a direct contraindication with birth control pills. However, the nurse should be aware of potential interactions and advise the client accordingly.

Choice B Reason:

Advising the client that the birth control pills will be less effective while taking doxycycline hyclate is crucial. Antibiotics like doxycycline can reduce the effectiveness of hormonal contraceptives, increasing the risk of unintended pregnancy. The client should be informed about this interaction and advised to use an additional non-hormonal method of contraception, such as condoms, while taking the antibiotic and for a short period after completing the course.

Choice C Reason:

Instructing the client to take the two medications at least two hours apart is not relevant in this case. The interaction between doxycycline and birth control pills is not related to the timing of administration but rather to the potential reduction in the effectiveness of the contraceptive.

Choice D Reason:

Encouraging the client to stop taking birth control pills until she has finished taking all the doxycycline hyclate is not advisable. Stopping birth control pills can lead to a disruption in the contraceptive regimen and increase the risk of unintended pregnancy. Instead, the client should be advised to use an additional method of contraception.
