The nurse is caring for a client with a total calcium level of 7.0 mg/dL. To assess for Chvostek's sign, the nurse would:

strain all of the client's urine.

inflate a blood pressure cuff 20 mmHg above systolic measurement.

lightly percuss the client's cheek.

obtain a baseline height and weight.

Answer and Explanation

The Correct Answer is C

C. Chvostek's sign is assessed by tapping or lightly percussing the facial nerve (facial muscles) at the angle of the jaw, just in front of the earlobe. A positive Chvostek's sign is indicated by facial twitching, especially around the mouth, nose, and eye, in response to this percussion. It indicates neuromuscular irritability due to low calcium levels.

A. Straining urine is typically done to collect urine for analysis or to detect urinary stones. It does not relate to the assessment of neuromuscular irritability, which is what Chvostek's sign evaluates.

B. This option does not pertain to assessing Chvostek's sign either. Inflating a blood pressure cuff above systolic measurement is a technique used to assess for Trousseau's sign, which is another clinical indicator of hypocalcemia but involves different physiological mechanisms than Chvostek's sign.

D. This option is unrelated to assessing Chvostek's sign or hypocalcemia. Baseline height and weight are typically obtained for nutritional assessment, growth monitoring, or as part of a general health assessment. They do not help in evaluating neuromuscular irritability associated with calcium levels.

Correct Answer is ["A","B","D"]

Explanation

A. This is the part of the IV administration set that pierces the IV bag or bottle to allow fluid to flow into the tubing. The plastic insertion spike must remain sterile because it comes into direct contact with the fluid within the IV container. Contamination of the spike could introduce microorganisms into the IV solution.

B. The catheter adapter or hub is the part of the IV administration set where the IV catheter or cannula connects. It is crucial for this part to remain sterile to prevent introducing pathogens into the bloodstream during catheter insertion or manipulation.

D. The Y-site injection port is a branching point in the IV tubing where additional medications or fluids can be infused into the IV line. It must remain sterile to prevent contamination when administering medications or secondary infusions.

C. The drip chamber is located in the IV tubing, just below the IV bag or bottle. It is designed to visualize and regulate the flow of IV fluid into the patient. It does not directly contact the bloodstream or the IV fluid inside the tubing.

E. Roller clamp to regulate flow (Option E) does not necessarily need to be sterile because it does not come into direct contact with IV fluid or the patient's bloodstream. However, it should be handled with clean hands to maintain general cleanliness and to prevent contamination of other sterile parts of the IV set.
