A client's Sodium level is 128 meq/L. The nurse knows that a likely cause of this lab finding is:
Deficient intake of protein.
Administration of hypotonic IV fluids.
Excessive dietary intake of salt.
Overdose of supplemental Potassium pills.
The Correct Answer is B
A likely cause of a low sodium level (hyponatremia) of 128 mEq/L is the administration of hypotonic IV fluids. Hypotonic IV fluids have a lower concentration of solutes compared to the body's fluids, which can lead to dilutional hyponatremia. When these fluids are administered, they can cause water to move into the cells, diluting the sodium concentration in the bloodstream.

Correct Answer is C
Explanation
The patient bending over the sink while brushing teeth requires intervention by the nurse. After hip arthroplasty using the posterior approach, the patient should avoid bending at the hip greater than 90 degrees to prevent dislocation of the prosthesis. The nurse should instruct the patient to bend at the knees instead of the hips while brushing teeth or doing any other activity that requires bending. The other actions mentioned in the options are appropriate for a patient after hip arthroplasty.
Correct Answer is A
Explanation
A 3% saline solution is a hypertonic solution used to increase serum sodium levels in cases of severe hyponatremia. However, it can lead to fluid overload and pulmonary edema. The presence of crackles throughout both lung fields indicates the accumulation of fluid in the lungs, which is a serious adverse outcome.
The patient's radial pulse rate of 105 beats/min is within a normal range and does not directly indicate an adverse effect of the saline infusion.
The presence of sediment and blood in the patient's urine may be unrelated to the 3% saline infusion and could indicate other issues such as urinary tract infection or kidney injury.
An increase in blood pressure from 66/50 to 122/74 mmHg is an expected effect of a hypertonic solution like 3% saline, as it can cause an increase in intravascular volume. While the increase in blood pressure is significant, it does not represent an adverse outcome specific to the infusion itself.
