HESI Fundamentals

Correct Answer: A

Rationale: The priority nursing action is to restore circulation by loosening the restraint (A) because blue fingers (cyanosis) indicate decreased circulation. Comparing hand color bilaterally (C) and palpating the right radial pulse (D) are important assessments to gather more information, but they do not have the priority of addressing the decreased circulation by loosening the restraint. Applying a pulse oximeter (B) is not indicated in this scenario as it measures the saturation of hemoglobin with oxygen, which is not relevant when cyanosis is related to mechanical compression from the restraints.

Correct Answer: A

Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.

Correct Answer: C

Rationale: When a client is on contact precautions due to an infected draining wound, it is important to prevent contact with wound secretions. Therefore, disposing of soiled dressings in securely closed plastic bags helps contain and prevent the spread of infectious material, reducing the risk of transmission to others in the household.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid foods high in iodine.' Clients with hyperthyroidism should avoid foods high in iodine to prevent exacerbation of their condition. Iodine is an essential component in thyroid hormone production, and excessive iodine intake can worsen hyperthyroidism symptoms. Taking medication with meals (B) can interfere with the absorption of certain thyroid medications. Monitoring weight daily (C) is more relevant for conditions that may lead to weight changes like hypothyroidism. Decreasing fluid intake (D) is not a standard recommendation for hyperthyroidism unless specifically indicated by the healthcare provider.

Correct Answer: C

Rationale: In right-sided heart failure, the heart's inability to effectively pump blood to the lungs leads to fluid backup in the systemic circulation, resulting in peripheral edema (swelling in lower extremities). While jugular vein distention (A) and hepatomegaly (D) can also occur in right-sided heart failure, peripheral edema is a hallmark sign due to fluid retention. Crackles in the lungs (B) are more commonly associated with left-sided heart failure, where fluid accumulates in the lungs.
