Mrs. Tan is scheduled to undergo percutaneous transluminal coronary angioplasty (PTCA). Which of the following is the priority goal for her immediately after the procedure?

Correct Answer: B

Rationale: Maintaining blood pressure control is the priority goal for Mrs. Tan immediately after percutaneous transluminal coronary angioplasty (PTCA). PTCA is a procedure used to open narrowed or blocked arteries in the heart. After the procedure, there is a risk of abrupt changes in blood pressure due to various factors, such as contrast dye used during the procedure, stress on the heart, and potential complications. Maintaining stable blood pressure is crucial to ensure adequate perfusion to the heart and other organs. Monitoring and controlling blood pressure help prevent further complications and promote a smooth recovery process for the patient. It is important to address this priority goal to optimize Mrs. Tan's post-procedure outcomes.

Correct Answer: C

Rationale: In a young child like Clay who is diagnosed with heart failure, following the directed therapeutic regimen would involve maintaining a normal weight for his age. Weight monitoring is crucial in managing heart failure as excessive weight gain could lead to worsening of symptoms and complications. Ensuring that Clay stays within a normal weight range for his age shows his adherence to dietary recommendations, fluid restrictions, and overall treatment plan aimed at managing his heart failure effectively. Monitoring his weight would also help healthcare providers assess if the treatment plan is working and make necessary adjustments as needed. Therefore, Clay maintaining a normal weight for his age indicates that he is strictly following the directed therapeutic regimen for his heart failure.

Correct Answer: C

Rationale: Performing chest physiotherapy (CPT) at least two hours after meals is important to prevent potential risks such as vomiting and aspiration. This timing allows for better tolerance of the procedure and decreases the likelihood of complications. By waiting at least two hours after meals, the nurse ensures that the patient's stomach is not full, reducing the risk of regurgitation during the chest physiotherapy session. This practice promotes the safety and well-being of the patient while undergoing this treatment.

Correct Answer: A

Rationale: Milk should not be given simultaneously with an oral iron supplement because calcium in milk can interfere with the absorption of iron. Calcium competes with iron for absorption in the digestive tract, thereby reducing the absorption of iron when both are taken together. It is advisable to wait at least 1-2 hours after giving the iron supplement before offering milk to ensure optimal absorption of iron. This is a common practice to improve iron absorption and prevent any potential decrease in the effectiveness of the iron supplement.

Correct Answer: A

Rationale: Respiratory acidosis is a condition characterized by elevated levels of carbon dioxide (high PCOâ‚‚) and decreased blood pH (low pH) due to inadequate ventilation leading to the accumulation of carbon dioxide in the body. The excess carbon dioxide reacts with water in the blood to form carbonic acid, resulting in a decrease in pH. This is in contrast to metabolic acidosis, which is characterized by an accumulation of acids other than carbon dioxide, leading to a low blood pH. Respiratory alkalosis would present with a low PCOâ‚‚ and high pH, while metabolic alkalosis features a high pH and elevated bicarbonate levels due to non-respiratory causes.
