HESI Fundamentals Practice Exam

Correct Answer: C

Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.

Correct Answer: A

Rationale: The wife is correctly performing the passive range-of-motion exercises by holding the arm above and below the elbow. The nurse should acknowledge this correct technique (A). It is essential to keep the joint uncovered (B) during exercises, while ensuring the rest of the body remains covered for warmth and privacy. Choices (C) and (D) do not provide optimal support to the joint for effective movement.

Correct Answer: D

Rationale: Before assisting the client out of bed, the nurse should first assess the client's blood pressure and pulse. This assessment is crucial to determine the client's physiological stability and readiness for ambulation. It ensures the client's safety during the transfer and helps prevent any potential complications that may arise from getting out of bed. Administering oxygen, lying the client back down, or quickly moving the client to a chair without assessing vital signs can compromise the client's safety and may lead to adverse outcomes.

Correct Answer: D

Rationale: Orthopnea (D) is most consistent with left-sided heart failure. It is characterized by difficulty breathing when lying flat and is relieved by sitting up or standing. Dependent edema (A), ascites (B), and nocturia (C) are more commonly associated with right-sided heart failure. Dependent edema refers to swelling due to fluid accumulation, ascites is the accumulation of fluid in the peritoneal cavity, and nocturia is the excessive need to urinate during the night, all of which are more indicative of right-sided heart failure.

Correct Answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.
