A nurse is caring for a client who is postoperative following cardiac surgery. Which of the following manifestations should indicate to the nurse that the client has developed a thrombus?

Positive Kernig's sign

Dull, aching calf pain

Soft, pliable calf muscle

Positive Homan's sign

Answer and Explanation

Correct Answer : B,D

A. Positive Kernig's sign:

Positive Kernig's sign is associated with meningitis, not thrombosis. It is a clinical sign where pain is elicited when the hip is flexed at a 90-degree angle and then the knee is extended. This sign is not relevant for identifying a thrombus.

B. Dull, aching calf pain:

Dull, aching calf pain is a common symptom of deep vein thrombosis (DVT). Pain, swelling, and tenderness in the calf are typical manifestations of a thrombus in the leg veins. This symptom should alert the nurse to the possibility of a thrombus.

C. Soft, pliable calf muscle:

A soft, pliable calf muscle is not indicative of a thrombus. In the case of DVT, the affected leg is usually swollen, firm, and tender. Thus, this manifestation does not suggest the presence of a thrombus.

D. Positive Homan's sign:

Positive Homan's sign is identified when there is pain in the calf upon dorsiflexion of the foot. This sign can be indicative of DVT. Although not highly specific or sensitive, it is one of the traditional signs used to assess for the presence of a thrombus in the leg.

Correct Answer is D

Explanation

(A) Respiratory acidosis: Respiratory acidosis is characterized by a low pH (<7.35) and a high PaCO2 (>45 mm Hg). In this case, the client’s pH is high and PaCO2 is normal, which rules out respiratory acidosis.

(B) Respiratory alkalosis: Respiratory alkalosis is characterized by a high pH (>7.45) and a low PaCO2 (<35 mm Hg). Although the client’s pH is high, the PaCO2 is normal, which rules out respiratory alkalosis.

(C) Metabolic acidosis: Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (<22 mEq/L). The client’s pH and bicarbonate levels are both high, which rules out metabolic acidosis.

(D) Metabolic alkalosis: Metabolic alkalosis is characterized by a high pH (>7.45) and a high bicarbonate level (>26 mEq/L). The client’s pH is 7.6 and bicarbonate level is 32 mEq/L, both of which are higher than normal. This indicates metabolic alkalosis. Therefore, the nurse should identify that the client is experiencing metabolic alkalosis.

A. Review the client's toxicology laboratory report. B. Administer the Hamilton depression scale. C. Initiate one-to-one nursing observation. D. Make a contract with the client for weight gain.

Correct Answer is C

Explanation

(A) Review the client's toxicology laboratory report:
While reviewing the toxicology report is important to understand any substances that may have been ingested, it is not the immediate priority compared to ensuring the client's safety.

(B) Administer the Hamilton depression scale:
Administering the Hamilton depression scale can help assess the severity of the client's depression, but immediate safety measures take precedence over assessment tools upon admission after a suicide attempt.

(C) Initiate one-to-one nursing observation:
Initiating one-to-one nursing observation is the most immediate and crucial action to ensure the client's safety. After a suicide attempt, continuous observation is essential to prevent further self-harm and ensure the client's immediate safety.

(D) Make a contract with the client for weight gain:
While addressing anorexia nervosa and making a contract for weight gain is important for the client's long-term treatment plan, it is not the first priority. Ensuring immediate safety through continuous observation is the most critical initial step.
