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?

Heart rate of 66/min

BP of 148/94 mm Hg

Peripheral edema of the ankles

A digoxin level of 1.2 ng/mL.

Answer and Explanation

The Correct Answer is C

(a) Heart rate of 66/min:
A heart rate of 66/min is within the normal range (60-100 bpm) and does not typically require contacting the provider before administering a calcium channel blocker. CCBs can affect heart rate, but this finding alone is not a contraindication for their use.

(b) BP of 148/94 mm Hg:
A blood pressure reading of 148/94 mm Hg indicates hypertension, which is an appropriate indication for the use of calcium channel blockers. This finding supports the use of the medication rather than requiring the provider to be contacted.

(c) Peripheral edema of the ankles:
Peripheral edema is a known side effect of calcium channel blockers. If the client is already experiencing edema, administering the medication could potentially worsen this condition. The nurse should contact the provider to discuss this finding before proceeding with the medication administration.

(d) A digoxin level of 1.2 ng/mL:
A digoxin level of 1.2 ng/mL is within the therapeutic range (0.5-2.0 ng/mL). This finding does not necessitate contacting the provider before administering a calcium channel blocker, as it does not indicate toxicity or a contraindication for CCB use

Correct Answer is ["A","B","C","D","F"]

Explanation

A. Is the research applicable to other populations? This is a crucial question in the critical appraisal of evidence. The applicability or generalizability of research findings to other populations is an important aspect of any study. If the study’s sample is representative and diverse, the findings are more likely to be applicable to other populations.

B. What methods were used to conduct the research? Understanding the methods used in a study is fundamental to evaluating its validity. The research design, data collection methods, and analysis techniques all contribute to the strength of the study’s findings.

C. How were the study results analyzed? The analysis of study results is a key component of research. The statistical methods used can greatly impact the interpretation of the results. Understanding how the results were analyzed can help determine if the conclusions drawn are valid.

D. Does the study have reliability? Reliability refers to the consistency or repeatability of the study’s findings. If a study is reliable, it means that if the study were repeated under the same conditions, it would produce the same results. This is a key factor in determining the quality of a study.

E. What were the costs associated with the research? While understanding the costs associated with research can be important in some contexts, it is not typically a key factor in the critical appraisal of the evidence itself. The focus of critical appraisal is more on the quality, validity, and applicability of the research rather than the costs involved in conducting it.

F. What was the purpose of the study? Understanding the purpose or objective of the study is a fundamental part of critical appraisal. It helps to determine whether the study design, methods, and analysis are appropriate for answering the research question.
