The practical nurse (PN) is assessing an older client with left-sided heart failure (HF). What intervention is most important for the PN to implement?
Inspect for sacral edema.
Measure urinary output.
Auscultate all lung fields.
Check mental acuity.
The Correct Answer is C
When assessing an older client with left-sided heart failure (HF), the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. Left-sided heart failure is characterized by the inability of the left ventricle to effectively pump blood, leading to fluid accumulation in the lungs. Auscultating all lung fields allows the PN to assess for the presence of abnormal lung sounds such as crackles, indicating pulmonary congestion.
Let's evaluate the other options:
a) Inspect for sacral edema.
Sacral edema is commonly associated with right-sided heart failure, not left-sided heart failure. While it is important to assess for edema in clients with heart failure, inspecting for sacral edema may not be the most immediate and crucial intervention in this specific case.
b) Measure urinary output.
Measuring urinary output is a valuable assessment in many clinical situations, but it may not be the most vital intervention in the context of left-sided heart failure. Monitoring urinary output is more relevant in assessing kidney function and fluid balance rather than directly assessing the severity of left-sided heart failure.
d) Check mental acuity.
Checking mental acuity is important in assessing the overall condition of the client, but it is not the most crucial intervention specifically related to left-sided heart failure. Mental status evaluation is more useful in identifying signs of altered mental status or potential complications, rather than directly assessing the impact of left-sided heart failure.
In summary, when assessing an older client with left-sided heart failure, the most important intervention for the practical nurse (PN) to implement is to auscultate all lung fields. This allows for the detection of abnormal lung sounds associated with pulmonary congestion, a hallmark sign of left-sided heart failure.

Correct Answer is A
Explanation
Choice A rationale:
Protamine sulfate is an antidote for heparin overdose and should be administered slowly intravenously to avoid rapid hemodynamic changes and potential adverse reactions.Administering it within 30 minutes ensures timely reversal of heparin’s anticoagulant effects.
Choice B rationale:
Administering protamine sulfate rapidly intramuscularly is incorrect because intramuscular administration is not recommended due to the risk of hematoma formation and slower absorption compared to intravenous administration.
Choice C rationale:
While slow intravenous administration is correct, the timing of 60 minutes is less effective compared to 30 minutes for reversing heparin’s effects promptly.
Choice D rationale:
Rapid intramuscular administration is incorrect for the same reasons as Choice B.Rapid administration can cause adverse reactions, and intramuscular administration is not the preferred route.
Correct Answer is D
Explanation
This is the correct answer because BUN and creatinine are the most important laboratory values to monitor for nephrotoxicity, which is the damage or injury to the kidneys caused by certain drugs or chemicals.
Nephrotoxicity can impair the kidneys' ability to filter waste products from the blood, resulting in elevated levels of BUN and creatinine. The normal range for BUN is 7 to 20 mg/dL, and for creatinine is 0.6 to 1.2 mg/dL. The practical nurse (PN) should review these values before administering an antibiotic that can cause nephrotoxicity, such as aminoglycosides, cephalosporins, vancomycin, or sulfonamides. The PN should also monitor the client for signs and symptoms of nephrotoxicity, such as decreased urine output, edema, hypertension, fatigue, nausea, and confusion.
a) Serum calcium
This is not the correct answer because serum calcium is not directly related to nephrotoxicity. Serum calcium is the amount of calcium in the blood, which is important for bone health, muscle contraction, nerve function, and blood clotting. The normal range for serum calcium is 8.5 to 10.2 mg/dL. Serum calcium may be affected by kidney disease, but it is not a reliable indicator of nephrotoxicity.
b) Hemoglobin and hematocrit
This is not the correct answer because hemoglobin and hematocrit are not directly related to nephrotoxicity. Hemoglobin is the protein in red blood cells that carries oxygen, and hematocrit is the percentage of red blood cells in the blood. The normal range for hemoglobin is 13.5 to 17.5 g/dL for men and 12 to 15.5 g/dL for women, and for hematocrit is 38.8 to 50% for men and 34.9 to 44.5% for women.
Hemoglobin and hematocrit may be affected by kidney disease, but they are not reliable indicators of
nephrotoxicity.
c) White blood cell count (WBC)
This is not the correct answer because WBC is not directly related to nephrotoxicity. WBC is the number of white blood cells in the blood, which are part of the immune system and fight infections. The normal range for WBC is 4,500 to 10,000 cells per microliter of blood. WBC may be elevated in response to an infection or inflammation, but it is not a reliable indicator of nephrotoxicity.
