A nurse in an emergency department is assessing a client who is overusing prescribed diuretics and has a sodium level of 127 mEq/L. Which of the following laboratory findings should the nurse expect?
High lipase.
High creatine kinase-MB (CK-MB).
Low hemoglobin.
Low urine specific gravity.
The Correct Answer is D
Choice A rationale:
High lipase is not a typical laboratory finding related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Lipase is an enzyme involved in lipid digestion and is more relevant in assessing pancreatic function.
Choice B rationale:
High creatine kinase-MB (CK-MB) is not associated with overusing prescribed diuretics or hyponatremia (low sodium level). CK-MB is a specific marker for myocardial damage and is usually elevated in conditions like myocardial infarction.
Choice C rationale:
Low hemoglobin is not directly related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Low hemoglobin may indicate anemia or other hematological issues but this is not a typical finding in this scenario.
Choice D rationale:
The correct answer is low urine specific gravity. Overusing diuretics can lead to excessive urination, causing the urine to become more dilute with lower specific gravity. A low urine specific gravity indicates decreased urine concentration and can be a sign of fluid and electrolyte imbalances, including hyponatremia.

Correct Answer is C
Explanation
Choice A rationale:
Expiratory rhonchi are typically associated with conditions such as chronic bronchitis or asthma but are not specific to pulmonary embolism.
Choice B rationale:
Petechiae over the lower extremities is not a characteristic finding in pulmonary embolism. Petechiae are tiny red or purple spots that appear due to bleeding under the skin and may be associated with other conditions like thrombocytopenia.
Choice C rationale:
The correct choice. Hemoptysis, which refers to coughing up blood, is a concerning finding in pulmonary embolism. It occurs due to the obstruction of blood flow in the pulmonary vasculature, leading to blood leaking into the lungs.
Choice D rationale:
Flattened neck veins are more likely to be observed in conditions associated with decreased venous return to the heart, such as hypovolemia or cardiac tamponade, and are not directly related to pulmonary embolism.
Correct Answer is A
Explanation
Choice A rationale:
A decrease in NG tube drainage indicates that the client's stomach contents are not being aspirated excessively, which suggests that the IV fluids are effectively maintaining fluid volume balance. This finding is positive because it shows that the client is retaining the fluids they need, and it may also indicate improved gastrointestinal function and decreased risk of dehydration.
Choice B rationale:
The potassium level of 3.3 mEq/L (milliequivalents per liter) is low. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. Hypokalemia (low potassium) can result from various factors and may cause muscle weakness, cardiac arrhythmias, and other complications. It is not a finding that indicates the effectiveness of fluid volume balance therapy.
Choice C rationale:
An increased heart rate may suggest that the client is experiencing fluid volume deficit or other physiological stress. It is not a finding that indicates the effectiveness of fluid volume balance therapy.
Choice D rationale:
A hematocrit level of 46% is within the normal range for adult males (typically around 38.8% to 50%) and indicates the proportion of red blood cells in the blood. While it can provide information about blood viscosity and hydration status, it does not directly indicate the effectiveness of fluid volume balance therapy.
