Correct Answer: C

Rationale: The correct action the nurse should take is to place the client in a prone position for 30 minutes four times a day. This position helps prevent contractures after an amputation by stretching the hip flexors and preventing shortening of the residual limb. Keeping the residual limb flat on the bed (Choice A) may lead to contractures. Elevating the residual limb on a pillow (Choice B) can also cause contractures and hinder proper healing. Keeping the residual limb dependent (Choice D) is not recommended as it does not promote proper positioning and circulation.

Correct Answer: C

Rationale: Administering anticoagulants as prescribed is a crucial intervention for clients with pulmonary embolism to prevent further clot formation. Encouraging the client to ambulate frequently may dislodge the clot and lead to worsening symptoms. Placing the client in a prone position can compromise respiratory function. Initiating seizure precautions is not directly related to the management of pulmonary embolism.

Correct Answer: C

Rationale: The correct answer is C: Potassium 5.2 mEq/L. A potassium level of 5.2 mEq/L is elevated and should be monitored in clients taking spironolactone, which is a potassium-sparing medication. Monitoring potassium levels is crucial as spironolactone can cause hyperkalemia. Choices A, B, and D are incorrect because sodium, calcium, and magnesium levels are not typically affected by spironolactone. Therefore, the nurse should primarily focus on monitoring the potassium levels in this scenario.

Correct Answer: B

Rationale: A positive antinuclear antibody (ANA) titer is a significant finding in clients with systemic lupus erythematosus (SLE) as it indicates active disease. This result should be reported to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and not specifically indicative of disease activity in SLE. Therefore, they do not require immediate reporting to the provider.

Correct Answer: B

Rationale: In clients with cirrhosis, albumin levels are typically decreased due to impaired liver function. Bilirubin levels are often increased in cirrhosis due to the liver's inability to process bilirubin efficiently. Ammonia levels may be elevated in cirrhosis due to impaired ammonia metabolism by the liver. Prothrombin time is usually prolonged in cirrhosis because the liver's ability to synthesize clotting factors is impaired.
