Which of the ff nursing interventions is required when caring for a client after cardiac surgery who is at risk for ineffective tissue perfusion?

Correct Answer: C

Rationale: The correct answer is C: Position lower extremities below level of heart. This intervention helps improve blood flow and perfusion to the lower extremities by utilizing gravity to assist in venous return. This is crucial for clients at risk for ineffective tissue perfusion post-cardiac surgery. A: Restricting fluid intake may lead to dehydration, which can worsen tissue perfusion. B: Ensuring the client avoids prolonged sitting is important for preventing blood clots, but it does not directly address tissue perfusion. D: Instructing the client to avoid leg exercises may hinder circulation and exacerbate issues related to tissue perfusion.

Correct Answer: C

Rationale: The correct answer is C: Toilet the patient according to his pre-illness schedule, whether or not he feels the urge. This intervention helps establish a routine for bowel movements, which can aid in reducing episodes of bowel incontinence. By following the patient's pre-illness schedule, the nurse can help regulate bowel movements and prevent accidents. A: Asking the patient frequently if he has to have a bowel movement may not address the underlying issue of bowel incontinence. B: Placing incontinence pads on the patient's bed and chair is a reactive measure and does not address the root cause of the issue. D: Taking care not to embarrass the patient when incontinent episodes occur is important for emotional support but does not directly address reducing episodes of bowel incontinence.

Correct Answer: C

Rationale: The correct answer is C: Jello. A clear liquid diet includes transparent liquids and foods that are liquid at room temperature. Jello meets this criteria as it is a clear, easily digestible food. Milk (A) is not allowed on a clear liquid diet due to its opaque nature. Orange juice (B) contains pulp and is not considered clear. Ice cream (D) is a solid food and not permitted on a clear liquid diet. Therefore, Jello is the most suitable option for someone on a clear liquid diet.

Correct Answer: D

Rationale: Step 1: Monitoring electrolytes is essential to assess for potential imbalances due to the use of sodium bicarbonate, which can lead to hypokalemia and hypocalcemia. Step 2: Hypokalemia and hypocalcemia can result in serious complications such as cardiac arrhythmias and muscle weakness. Step 3: By monitoring electrolytes, the nurse can detect imbalances early and intervene promptly to prevent adverse effects. Summary: A: Drinking excessive water can lead to electrolyte imbalances and is not directly related to the use of sodium bicarbonate. B: Administering NaHCO3 IV is not within the nurse's scope of practice and should be done based on physician's orders. C: Continuing sodium bicarbonate for nausea may not be appropriate without monitoring electrolytes to prevent potential imbalances.

Correct Answer: B

Rationale: The correct answer is B because inserting a mouth gag during a convulsive seizure can obstruct the airway and pose a choking hazard. Step-by-step rationale: A: Loosening clothing helps improve ventilation. C: Positioning on the side with head flexed forward prevents aspiration. D: Providing privacy is important for patient dignity and confidentiality. B is incorrect as it can be harmful.
