The nurse is completing a cardiac assessment on a client. The pulmonic valve would best be assessed by auscultating at the:

second intercostal space, left sternal border.

third intercostal space, left sternal border.

second intercostal space, right sternal border

fourth intercostal space, left sternal border.

Answer and Explanation

The Correct Answer is A

A. The pulmonic valve is best auscultated at the second intercostal space (ICS) on the left sternal border. This is where the area corresponding to the pulmonic valve is most accurately heard due to the anatomical positioning of the heart.

B. This area does not correspond to any valvular area.

C. This location corresponds to the aortic valve, not the pulmonic valve. The aortic valve is best auscultated at the second ICS, right sternal border.

D. This location corresponds to the tricuspid valve, not the pulmonic valve. The tricuspid valve is best auscultated at the fourth or fifth ICS along the left sternal border.

Correct Answer is ["1705"]

Explanation

To calculate the cumulative fluid intake for the client from 3 p.m. to 11 p.m., convert all measurements to the same unit and then sum them up.

First, convert ounces to milliliters (1 ounce = 29.5735 ml). The tea is 4 ounces, which is approximately 118 ml, and the soda is 6 ounces, approximately 177 ml.

Add all the liquid intake: chicken broth (120 ml) + tea (118 ml) + ice cream (assumed to be 240 ml for 1 cup) + soda (177 ml) + water (550 ml) + half the volume of ice chips (as half the volume of ice chips is water, so 250 ml). The total intake is 120 + 118 + 240 + 177 + 550 + 500= 1705 ml.

Since the intake and output are calculated at 2200, and the client has not consumed anything after 2115, the cumulative fluid intake for the shift is 1705 ml.

A. strain all of the client's urine. B. inflate a blood pressure cuff 20 mmHg above systolic measurement. C. lightly percuss the client's cheek. D. obtain a baseline height and weight.

Correct Answer is C

Explanation

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.
