A nurse is collecting data from a client prior to administering a calcium channel blocker (CCB) for treatment of hypertension. For which of the following findings should the nurse contact the provider?
A.
Heart rate of 66/min
B.
BP of 148/94 mm Hg
C.
Peripheral edema of the ankles
D.
A digoxin level of 1.2 ng/mL.
The Correct Answer and Explanation is:
The correct answer is B. BP of 148/94 mm Hg.
Explanation
When a nurse is preparing to administer a calcium channel blocker (CCB) for hypertension, it’s crucial to evaluate several key parameters to ensure the medication’s safety and efficacy. CCBs, such as amlodipine, diltiazem, and verapamil, are used to lower blood pressure by causing vasodilation and reducing the workload on the heart.
1. Heart Rate of 66/min: A heart rate of 66 beats per minute is generally within the normal range for most adults, though slightly on the lower side of normal. CCBs can sometimes lower heart rate, but a heart rate of 66/min is not typically a concern unless it is accompanied by symptoms of bradycardia or if the patient is on other medications that might further lower the heart rate.
2. BP of 148/94 mm Hg: The target blood pressure for a client receiving treatment for hypertension is usually below 140/90 mm Hg, as recommended by most clinical guidelines. A reading of 148/94 mm Hg indicates that the patient’s blood pressure is still elevated, despite the use of antihypertensive medications. This suggests that the current treatment regimen might be inadequate, and the dose of the CCB might need adjustment or additional antihypertensive agents might be necessary. Therefore, it is essential to contact the provider to reassess the treatment plan and determine the next steps for managing the patient’s hypertension effectively.
3. Peripheral Edema of the Ankles: Peripheral edema is a common side effect of CCBs, especially with dihydropyridine CCBs like amlodipine. While this side effect can be bothersome, it is usually not an indication to stop the medication unless it is severe or impacting the patient’s quality of life.
4. A Digoxin Level of 1.2 ng/mL: A digoxin level of 1.2 ng/mL is within the therapeutic range for digoxin, which is typically between 0.5 and 2.0 ng/mL. Therefore, this finding does not warrant contacting the provider unless there are specific concerns about digoxin toxicity or interactions with the CCB.
In summary, the elevated blood pressure reading (148/94 mm Hg) suggests that the patient’s hypertension is not well controlled, and thus it is important to consult with the provider to evaluate and adjust the treatment plan.
