Which finding should the nurse recognize as a potential complication in a client with hypertension?

Polydipsia and polyuria.

Elevated blood urea nitrogen.

Dry and irritated skin.

New onset of bradycardia.

Answer and Explanation

The Correct Answer is B

A. Polydipsia and polyuria: These symptoms are more commonly associated with uncontrolled diabetes mellitus rather than hypertension. They are not direct complications of elevated blood pressure.

B. Elevated blood urea nitrogen: Hypertension can damage renal blood vessels, leading to impaired kidney function and elevated BUN levels. This is a significant complication that indicates progressive end-organ damage.

C. Dry and irritated skin: This is a nonspecific symptom that may result from dermatologic conditions, dehydration, or environmental factors. It is not typically associated with hypertension complications.

D. New onset of bradycardia: Bradycardia is not a usual complication of hypertension itself, though it may occur as a side effect of certain antihypertensive medications such as beta-blockers. It is not a primary complication to anticipate.

Correct Answer is ["18"]

Explanation

Calculation:

Convert the client's weight from pounds (lb) to kilograms (kg).

The client's weight is 220 lb.

Client weight (kg) = 220lb/2.2lb/kg

= 100kg.

Calculate the total heparin dose to be administered per hour (units/hr).

The ordered rate is 18 units/kg/hour.

Total dose rate (units/hr) = 18units/kg/hour×100kg

= 1800units/hr.

Determine the concentration of the available solution (units/mL).

Available solution is 25,000units in 250mL.

Concentration (units/mL) = 25,000units/250mL

= 100units/mL.

Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Totaldoserate(units/hr)/Concentration(units/mL)

= 1800units/hr/100units/mL

= 18mL/hr.

A. Position the client's head facing away from the site. B. Aspirate for the presence of a blood return. C. Prepare a saline flush in a three mL syringe. D. Initiate an infusion of 0.9% normal saline solution.

Correct Answer is B

Explanation

A. Position the client's head facing away from the site: While positioning can help reduce the risk of infection or discomfort, it does not ensure that the catheter is patent or safe for medication administration.

B. Aspirate for the presence of a blood return: Confirming blood return verifies that the central venous catheter is patent and correctly positioned in the bloodstream. This is a critical safety step before administering intravenous medications to prevent extravasation or ineffective delivery.

C. Prepare a saline flush in a three mL syringe: While flushing the catheter is important for maintaining patency, the nurse must first confirm the catheter is patent by aspirating for blood return before flushing or administering medication.

D. Initiate an infusion of 0.9% normal saline solution: Starting a continuous infusion is not necessary solely for medication administration. The priority is confirming patency and safe access, after which flushing and medication administration can proceed.
