Question 1 of 5
When administering enoxaparin (Lovenox) to a client, what is the most important lab value to monitor?
Correct Answer: A
Rationale: The correct answer is A: Platelet count. When administering enoxaparin, the most important lab value to monitor is the platelet count because enoxaparin can cause thrombocytopenia, a potentially serious adverse effect. Monitoring platelet count helps to detect and prevent this complication. Summary of other choices: B: aPTT - Enoxaparin does not directly affect aPTT, so monitoring this value is not as critical as platelet count. C: Hemoglobin - While monitoring hemoglobin may be important for some conditions, it is not the most crucial lab value to monitor when administering enoxaparin. D: INR - Enoxaparin does not affect the INR, so monitoring this value is not necessary when administering this medication.
Question 2 of 5
A client on spironolactone (Aldactone) has a potassium level of 6.0 mEq/L. What is the nurse's priority action?
Correct Answer: A
Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With a potassium level of 6.0 mEq/L, the client is at risk for serious cardiac complications. Holding the medication and notifying the healthcare provider is the priority to prevent further increase in potassium levels. Administering a potassium supplement (B) would exacerbate the hyperkalemia. Continuing the spironolactone as ordered (C) or increasing the dose (D) would also worsen the situation.
Question 3 of 5
The client on a beta blocker has a blood pressure of 88/58 mm Hg. What is the nurse's priority action?
Correct Answer: A
Rationale: The correct answer is A: Hold the beta blocker and notify the healthcare provider. A blood pressure of 88/58 mm Hg is considered hypotension, which can be a serious side effect of beta blockers. By holding the medication and notifying the healthcare provider, the nurse ensures prompt assessment and appropriate intervention. Administering the beta blocker (B) could further lower the blood pressure. Increasing the dose (C) would exacerbate the hypotension. Continuing to monitor and reassess (D) is not sufficient as immediate action is required due to the low blood pressure reading.
Question 4 of 5
A patient with heart failure has tachypnea, severe dyspnea, and a SpO2 of 84%. The nurse identifies a nursing diagnosis of impaired gas exchange related to increased preload and mechanical failure. An appropriate nursing intervention for this diagnosis is
