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?

pH.

Calcium.

Potassium.

Phosphate.

Answer and Explanation

The Correct Answer is D

pH: Calcium acetate is not directly related to changes in blood pH. Therefore, monitoring pH levels would not indicate the effectiveness of the medication for CKD.

B) Calcium: Calcium levels may be affected by calcium acetate, but the primary goal of using calcium acetate in CKD is to reduce phosphate levels, not calcium levels. Therefore, monitoring calcium levels would not directly indicate the effectiveness of the medication.

C) Potassium: Calcium acetate is not typically used to affect potassium levels. Monitoring potassium levels would not indicate the effectiveness of calcium acetate for CKD.

D) Phosphate: This is the correct answer. Calcium acetate is a phosphate binder commonly used in CKD to help lower elevated phosphate levels. A decrease in phosphate levels in the blood would indicate that the medication is having the desired effect in controlling phosphate levels, which is important in managing CKD and preventing complications associated with hyperphosphatemia. Therefore, monitoring phosphate levels is essential to assess the effectiveness of calcium acetate therapy in CKD.

Correct Answer is B

Explanation

A) Increased frequency of lacrimation is not typically associated with miotic therapy. Miotics work by constricting the pupil and increasing outflow of aqueous humor to reduce intraocular pressure, but they do not directly affect lacrimation (tear production). Therefore, this option is not the etiology for the “Risk for injury” nursing problem.

B) Decreased night vision is a common side effect of miotic therapy. Miotics constrict the pupil, which can reduce the amount of light entering the eye, leading to impaired night vision or difficulty seeing in low-light conditions. This impaired vision increases the risk of injury, particularly in situations with reduced lighting.

C) Increased sensitivity to light (photophobia) is not typically associated with miotic therapy. Miotics constrict the pupil, which may actually reduce sensitivity to light by decreasing the amount of light entering the eye. Therefore, increased sensitivity to light is not the etiology for the “Risk for injury” nursing problem in this case.

D) Diminished color perception is not a common side effect of miotic therapy. Miotics primarily affect pupil constriction and intraocular pressure but do not typically alter color perception. Therefore, diminished color perception is not the etiology for the “Risk for injury” nursing problem.

A. Use a twice a week dosing schedule. B. Take the medication early in the day. C. Stand and sit up slowly. D. Reduce daily fluid intake.

Correct Answer is C

Explanation

A) Tamsulosin is typically administered once daily, not on a twice-weekly dosing schedule. Instructing the client to adhere to the prescribed dosing frequency is essential for maintaining therapeutic blood levels of the medication and optimizing its effectiveness in managing urinary retention associated with benign prostatic hyperplasia (BPH).

B) While the timing of medication administration can impact its effectiveness, taking tamsulosin early in the day versus later in the day may not significantly affect its therapeutic action. The key consideration with tamsulosin is to maintain consistency in timing to ensure a steady plasma concentration of the drug.

C) Instructing the client to stand and sit up slowly is crucial because tamsulosin, as an alpha-blocker, can cause orthostatic hypotension, especially when first starting the medication or when increasing the dosage. By advising the client to change positions slowly, the nurse helps prevent falls and dizziness, which are common side effects associated with sudden drops in blood pressure.

D) Reducing daily fluid intake is not advisable, especially for a client with urinary retention. Maintaining adequate hydration is essential for overall health and urinary function. Tamsulosin works by relaxing the smooth muscles of the prostate and bladder neck, facilitating urine flow, but it does not directly affect fluid intake requirements.

Therefore, the most important instruction for the nurse to provide is to stand and sit up slowly to minimize the risk of orthostatic hypotension and associated complications.
