A nurse is monitoring a client's lower extremity following the placement of a cast earlier in the day. Which of the following findings should the nurse identify as manifestations of compartment syndrome? (Select all that apply.)

Pale-colored toes

Decreased skin turgor

Pain relieved by analgesia

Diminished capillary refill

Sensation of tingling

Answer and Explanation

Correct Answer : A,D,E

A. Pale-colored toes are a sign of compromised circulation, which is a key manifestation of compartment syndrome. Decreased blood flow to the affected limb can cause pallor, which requires immediate intervention to prevent permanent damage.

B. Decreased skin turgor is incorrect. Skin turgor is an indicator of hydration status and is not directly related to compartment syndrome.

C. Pain relieved by analgesia is incorrect. One of the hallmark signs of compartment syndrome is severe pain that is not relieved by analgesia and worsens with passive movement.

D. Diminished capillary refill is correct. Delayed capillary refill (longer than 2 seconds) suggests poor perfusion, which can indicate increased pressure within the compartment.

E. Sensation of tingling is correct. Paresthesia (tingling or numbness) is an early sign of nerve compression due to swelling within the compartment. If untreated, this can progress to permanent nerve and muscle damage.

Correct Answer is B

Explanation

A. Instant coffee: Instant coffee generally contains more caffeine than brewed green tea or cola soft drinks. A typical 8 oz serving of instant coffee contains about 30–90 mg of caffeine.

B. Hot cocoa: This is correct. Hot cocoa contains the least amount of caffeine compared to the other options. An 8 oz serving typically contains around 5–10 mg of caffeine.

C. Brewed green tea: Brewed green tea typically contains more caffeine than hot cocoa, with an 8 oz serving containing around 30–50 mg of caffeine.

D. Cola soft drink: Cola soft drinks typically contain more caffeine than hot cocoa, with an 8 oz serving containing about 24–46 mg of caffeine.

A. "Take an extra dose of insulin lispro prior to aerobic exercise." B. "Draw up the insulin lispro and insulin glargine in separate syringes." C. "Expect insulin glargine to be cloudy." D. "Anticipate that the insulin glargine will peak in 3 hours."

Correct Answer is B

Explanation

A. "Take an extra dose of insulin lispro prior to aerobic exercise." This is incorrect. Exercise can increase insulin sensitivity, meaning the client may need to reduce the dose of short-acting insulin (such as insulin lispro) before exercise to avoid hypoglycemia. The nurse should not recommend taking an "extra" dose of insulin prior to exercise.

B. "Draw up the insulin lispro and insulin glargine in separate syringes." This is correct. Insulin lispro (a rapid-acting insulin) and insulin glargine (a long-acting insulin) should never be mixed in the same syringe. Insulin glargine is acidic, and mixing it with other insulins can alter its action and effectiveness.

C. "Expect insulin glargine to be cloudy." This is incorrect. Insulin glargine should be clear and colorless. If insulin glargine appears cloudy, it may indicate that the insulin is expired or has been improperly stored.

D. "Anticipate that the insulin glargine will peak in 3 hours." This is incorrect. Insulin glargine has no pronounced peak. It provides a steady release of insulin over 24 hours and is designed to be taken once daily.
