A nurse is assisting with the care of a client who has hypocalcemia. For which of the following signs should the nurse monitor?
Kernig's sign
Brudzinski's sign
Chvostek's sign
Cullen's sign
The Correct Answer is C
(A) Kernig’s sign: Kernig’s sign is a clinical sign in which severe stiffness of the hamstrings causes an inability to straighten the leg when the hip is flexed to 90 degrees. It is commonly associated with meningitis, not hypocalcemia.
(B) Brudzinski’s sign: Brudzinski’s sign is a symptom of meningitis. It is not associated with hypocalcemia.
(C) Chvostek’s sign: This is the most appropriate answer. Chvostek’s sign is a clinical sign of existing nerve hyperexcitability (tetany) seen in hypocalcemia. It refers to an abnormal reaction to the stimulation of the facial nerve.
(D) Cullen’s sign: Cullen’s sign is a medical term referring to superficial edema and bruising in the subcutaneous fatty tissue around the umbilicus. It is not associated with hypocalcemia.

Correct Answer is D
Explanation
A. Qualitative studies are considered to be one type of Level I evidence: Qualitative studies are not typically considered Level I evidence. The hierarchy of evidence is a rating system used to evaluate the strength of evidence presented in medical research. Level I evidence usually includes systematic reviews, meta-analyses, and randomized controlled trials.
B. Level Vil evidence comes from a meta-analysis of multiple peer-reviewed studies: This statement is not accurate. Meta-analyses and systematic reviews are usually considered Level I evidence, as they provide the highest level of evidence. They synthesize and analyze multiple studies on a topic to provide a comprehensive view of the current evidence.
C. Level I evidence includes evidence found in nursing textbooks: Nursing textbooks are not considered Level I evidence. They often include a mix of different levels of evidence, from expert opinion to systematic reviews. While they are a valuable resource for background information and clinical guidelines, they do not represent the highest level of evidence.
D. Level I evidence is considered to be the best evidence to support EBP: This is correct. Level I evidence, which includes systematic reviews, meta-analyses, and randomized controlled trials, is considered the highest level of evidence and provides the most reliable basis for decision-making in evidence-based practice

Explanation
A. "My mouth is very dry."
Dry mouth is a common side effect of lorazepam, but it does not directly indicate the effectiveness of the medication in reducing preoperative anxiety.

Numbness in the leg is not a typical effect of lorazepam and does not indicate the effectiveness of the medication in reducing preoperative anxiety.
C. "I feel very sleepy."
Feeling sleepy or drowsy is a common side effect of lorazepam, and it indicates that the medication has effectively reduced the client's preoperative anxiety.
D. "I am not hungry any longer."
Decreased appetite can be a side effect of lorazepam, but it is not a direct indicator of the medication's effectiveness in reducing preoperative anxiety.
