A nurse is applying cold therapy to a client's face following oral surgery. The nurse should identify that which of the following is a therapeutic effect of cold therapy?

Increased tissue metabolism

Reduced blood coagulation

Decreased edema formation

Improved blood flow

Answer and Explanation

The Correct Answer is C

A. Increased tissue metabolism: Cold therapy slows tissue metabolism by reducing enzymatic activity and cellular function, which helps minimize inflammation and tissue damage, not increase metabolism.

B. Reduced blood coagulation: Cold therapy typically promotes vasoconstriction, which supports blood clotting rather than reducing coagulation. This effect can help control minor bleeding after surgery.

C. Decreased edema formation: Cold therapy causes vasoconstriction, which limits fluid accumulation in tissues and reduces capillary permeability, leading to less swelling and edema formation at the surgical site.

D. Improved blood flow: Cold causes vasoconstriction, which decreases blood flow temporarily. This helps limit inflammation and edema but does not enhance circulation during application.

Correct Answer is B

Explanation

A. Testicular examination: Testicular cancer screening is typically encouraged from adolescence to around age 35, as it is more common in younger men. Routine testicular exams are not specifically recommended starting at age 50.

B. Colonoscopy: Colorectal cancer screening, such as colonoscopy, should begin at age 45 or 50 for individuals at average risk. It is a key preventive measure for detecting colorectal cancer in its early stages.

C. Clinical breast examination: Clinical breast exams may be done earlier, typically starting in the 20s or 30s, depending on risk factors. They are not newly initiated at age 50.

D. Fasting blood glucose: Screening for diabetes may begin as early as age 35 in adults with risk factors. It is important but not specifically recommended as a new screening starting at age 50.

A. Hyponatremia B. Hyperkalemia C. Hypocalcemia D. Hypermagnesemia

Correct Answer is A

Explanation

A. Hyponatremia: Vomiting and diarrhea cause significant fluid loss, often leading to a decrease in sodium levels in the blood (hyponatremia) due to loss of electrolytes and dilution from fluid replacement or retained water.

B. Hyperkalemia: Vomiting and diarrhea usually cause potassium loss, resulting in hypokalemia rather than hyperkalemia, as potassium is lost through gastrointestinal fluids.

C. Hypocalcemia: Calcium levels are generally not directly affected by vomiting and diarrhea, so hypocalcemia is less likely in this scenario.

D. Hypermagnesemia: Magnesium is typically lost with gastrointestinal losses; therefore, hypermagnesemia is uncommon with vomiting and diarrhea.
