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. Ferrous sulfate: Ferrous sulfate is an iron supplement used to treat or prevent low blood levels of iron (such as those caused by anemia or pregnancy). It is not used to treat high INR levels.
B. Heparin: Heparin is an anticoagulant, or blood thinner, that prevents the formation of blood clots. It would not be used to treat a high INR level, as it could potentially increase the INR even further.
C. Prednisone: Prednisone is a corticosteroid that reduces inflammation in the body. It is not used to treat high INR levels.
D. Vitamin K: This is correct. Vitamin K is used to help blood clot and is given to patients who have a high INR level to reduce the risk of bleeding. Warfarin works by blocking the effects of vitamin K, so giving vitamin K can help reverse the effects of warfarin and lower the INR.
Correct Answer is C
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.
B. "My leg feels numb."
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.
