Answer 1

1.

Physician ordered KCl, 60 mEq tid.

(tid= three times a day. ).

Availabe: 40 mEq /30 ml

i.e. 40 mEq is in 30ml

which means: 1 mEq is in 30/40 ml -----------(1)

Equation (1) × 60 gives:-

60 mEq will be in 30/40 × 60100

i.e 45 ml tid.

Ans.: 45 ml tid.

The nurse should administer 45 ml thrice a day.

i.e. 60 mEq tid = 45 ml tid

(2).

Given:

500 ml HESPAN in 3 hrs

Drop factor =15gtts/ml

1 ml contains 15 drops

Therefore 500 ml contains 15×500 drops

=7500drops

i.e.7500 drops in 3hrs

Implies : 7500 drops in 3× 60 minutes

7500 drops in 180 minutes

Which gives :- in one minute= 7500/180

=41.6 drops per minute

=42drops( approx)per minute

should be anticipated to delivere 500 ml of Hespan.

(3).

Given:

1000 ml LR for 12 hrs

Therefore in, 1 hr it should be 1000 ÷ 12

=83.3 ml

Answer= 83.3 ml should be programmed per hour in the IV pumb.

(4).

Weight of the child=47 pounds.

1 pound=.0.45 Kg

Therefore 47 pounds=47× 0.45

=21.15 kg

Answer: child weighs 21.15 kilograms.
