Medical Surgical HESI 2023

Correct Answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.

Correct Answer: C

Rationale: The correct answer is C: Risk for impaired attachment. Parents of a newborn with cleft lip and palate may face challenges in bonding with their child due to the physical appearance, impacting attachment. Promoting bonding between parents and the infant is crucial in this situation. Choice A (Parental role conflict) is incorrect as it focuses on conflicting roles rather than the attachment issue. Choice B (Risk for delayed growth and development) is not the priority issue in this scenario as the immediate concern is establishing a healthy attachment. Choice D (Anticipatory grieving) is not the priority patient problem as it pertains more to the emotional response to an anticipated loss, which is not the primary concern at this stage.

Correct Answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

Correct Answer: B

Rationale: The correct answer is to 'Shake the inhaler well before use.' This instruction is crucial as shaking the inhaler ensures the proper mixing of the medication, which is essential for its effective delivery. Option A is incorrect because using the inhaler only before bedtime may not provide adequate relief during the day. Option C is incorrect as exhaling fully is a good practice but not the most essential instruction. Option D is incorrect as taking two puffs every hour may exceed the recommended dosage and lead to adverse effects.

Correct Answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.
