A client has been receiving IV potassium therapy. Upon further assessment, the nurse notes the site has become erythematous and edematous. Which action by the nurse is most appropriate?

Flush the IV site with normal saline, then restart the IV potassium therapy

Discontinue the IV and restart in another site

Flush the IV site with heparin

Stop the IV site and check for blood return

Answer and Explanation

The Correct Answer is B

A. Flush the IV site with normal saline, then restart the IV potassium therapy: Flushing and restarting the infusion at the same site is not appropriate if there is redness and swelling, as these are signs of possible phlebitis or infiltration.
B. Discontinue the IV and restart in another site: This is the correct choice. Given the erythema and edema, which indicate possible complications like phlebitis or infiltration, the IV should be discontinued and restarted in a new site to prevent further complications.
C. Flush the IV site with heparin: This is not appropriate for erythema and edema and could exacerbate the problem. Heparin is used to maintain patency of IV lines, not to treat complications.
D. Stop the IV site and check for blood return: While checking for blood return is a good practice to assess for patency, the primary action should be to discontinue the IV and start a new one due to the complications at the site.

Correct Answer is B

Explanation

A. Hypercholesterolemia: This condition primarily affects cholesterol levels and is not directly associated with phosphorus imbalances. It does not typically cause hypophosphatemia.
B. Malnutrition: This is the correct choice. Malnutrition can lead to hypophosphatemia (low serum phosphorus levels) due to inadequate dietary intake of phosphorus and impaired absorption.
C. Renal insufficiency: Renal insufficiency generally causes hyperphosphatemia (high serum phosphorus levels) due to the kidneys' reduced ability to excrete phosphate, not hypophosphatemia.
D. Hypoparathyroidism: This condition is more commonly associated with hypocalcemia (low calcium levels) rather than hypophosphatemia. In some cases, hypoparathyroidism can cause elevated phosphorus levels, but not typically hypophosphatemia.

A. Weakness in upper extremities B. Headache C. Increased respiratory rate D. Blurred vision

Correct Answer is B

Explanation

A. Weakness in upper extremities: Spinal anesthesia generally affects the lower body, so weakness in the upper extremities is not typically related to this type of anesthesia.
B. Headache: This is the correct choice. A headache is a common post-operative complaint related to spinal anesthesia, often caused by a spinal fluid leak, leading to a post-dural puncture headache.
C. Increased respiratory rate: Spinal anesthesia typically does not affect respiratory rate significantly; it mainly impacts sensation and motor function below the level of anesthesia.
D. Blurred vision: This is not a common issue directly related to spinal anesthesia. Visual disturbances are not typical post-operative complaints associated with spinal anesthesia.
