A client presents to the clinic for a postoperative follow-up following surgical repair of a fractured radius.

The client reports their adult child prepares two meals a day for them to eat.

The client's weight is 55.9 kg (123 Ib) and height is 175 cm (69 in). What is the client's BMI?

Choice A rationale

Spironolactone is a potassium-sparing diuretic. Its mechanism of action involves blocking aldosterone receptors in the kidney's distal convoluted tubule and collecting duct, leading to increased sodium and water excretion while retaining potassium. Consequently, taking a potassium supplement concurrently would dangerously increase the risk of hyperkalemia, a condition characterized by high blood potassium levels (normal range is 3.5-5.0 mEq/L), which can cause life-threatening cardiac dysrhythmias.

Choice B rationale

Spironolactone's primary effect is on sodium and potassium balance, not calcium. Calcium supplements do not typically interact with spironolactone in a way that would cause a significant, adverse change in calcium levels. The nurse should instruct the client to avoid supplements that directly alter the electrolytes affected by the medication's mechanism of action.

Choice C rationale

Spironolactone does not significantly impact iron metabolism. Therefore, a client taking an iron supplement would not be at increased risk of an adverse interaction. Iron supplements are generally well-tolerated with spironolactone, and there is no contraindication for their concurrent use. The focus of client teaching should be on electrolytes directly affected by the medication.

Choice D rationale

Spironolactone does not have a direct or clinically significant interaction with magnesium supplements. While diuretics can sometimes affect magnesium levels, spironolactone's primary action is on potassium and sodium. Therefore, there is no major contraindication for the use of magnesium supplements, unlike the life-threatening risk associated with potassium supplementation. *.

Choice A rationale

The first step in inserting an indwelling urinary catheter, after gathering supplies and preparing the client, is to lubricate the tip. The application of a generous amount of water-soluble gel to the catheter tip reduces friction as it passes through the urethra. This is crucial for minimizing trauma to the urethral mucosa and decreasing client discomfort during insertion.

Choice B rationale

Positioning the sterile drape is a later step in the procedure, after the catheter has been prepared for insertion. The drape is used to create a sterile field and isolate the perineum. This helps prevent contamination of the sterile catheter and gloves from surrounding non-sterile areas, which is essential for maintaining sterility and preventing infection.

Choice C rationale

Cleansing the meatus with an antiseptic solution is a critical step, but it is performed after the catheter is lubricated and the sterile field is established. This action mechanically and chemically removes microorganisms from the perineal area, reducing the risk of introducing bacteria into the urinary tract during catheter insertion.

Choice D rationale

Attaching a prefilled syringe to the inflation hub is done after the catheter is fully inserted into the bladder and urine flow is established. This step is necessary to inflate the balloon, which secures the catheter in place and prevents it from being expelled. Doing this prematurely could cause urethral damage. *.
