A nurse is collecting data from a client who has heart failure, prior to the administration of furosemide.
For which of the following findings should the nurse withhold the medication?
Oxygen saturation of 95%.
Serum sodium level of 140 mEq/L.
Blood pressure of 80/40 mm Hg.
Serum potassium level of 4.8 mEq/L.
The Correct Answer is C
The correct answer is C.
Choice A: Oxygen saturation of 95% The normal oxygen saturation level is between 95% and 100%. An oxygen saturation of 95% is within the normal range, so the nurse would not need to withhold furosemide for this reason.
Choice B: Serum sodium level of 140 mEq/L The normal serum sodium levels range from 135 to 145 mEq/L. A serum sodium level of 140 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.
Choice C: Blood pressure of 80/40 mm Hg Furosemide is a potent diuretic that can lead to a significant depletion of electrolytes, which may lead to side effects such as muscle cramps and an irregular heartbeat. Low blood pressure (hypotension) is a potential side effect of furosemide. Normal blood pressure for adults is typically around 120/80 mm Hg. A blood pressure reading of 80/40 mm Hg is considerably lower than the normal range, indicating hypotension.
Choice D: Serum potassium level of 4.8 mEq/L The normal serum potassium levels range from 3.6 to 5.2 mEq/L. A serum potassium level of 4.8 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.

Correct Answer is A
Explanation
The correct answer is Choice A: Dull, aching calf pain.
Choice A rationale:
Dull, aching calf pain is a common symptom of deep vein thrombosis (DVT), which can occur postoperatively, especially after vascular surgery. This pain is often due to a blood clot forming in the deep veins of the leg.
Choice B rationale:
Positive Kernig's sign is associated with meningitis and not typically related to thrombus formation.
Choice C rationale:
Soft, pliable calf muscle is not indicative of a thrombus. A thrombus would more likely cause tenderness and swelling.
Choice D rationale:
Positive Homan's sign (pain in the calf upon dorsiflexion of the foot) can be an indicator of DVT, but it is less reliable than dull, aching calf pain.
Correct Answer is A
Explanation
The correct answer is choiceA. Heart rate 50/min.
Choice A rationale:
Atenolol is a beta-blocker that can significantly lower heart rate.A heart rate of 50/min is considered bradycardia (slow heart rate), and administering atenolol could further decrease the heart rate to a dangerously low level. Therefore, the nurse should withhold the medication in this case.
Choice B rationale:
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not contraindicate the use of atenolol. Therefore, this finding would not require withholding the medication.
Choice C rationale:
An oxygen saturation of 95% is within the normal range (typically 95-100%) and does not contraindicate the use of atenolol. Thus, this finding would not necessitate withholding the medication.
Choice D rationale:
While a blood pressure of 160/94 mm Hg indicates hypertension, atenolol is often prescribed to manage high blood pressure. Therefore, this finding would not require withholding the medication.
