HESI Medical Surgical Test Bank

Correct Answer: D

Rationale: The correct answer is D: Upper gingival mucosa in the space between the upper gums and lip. A transsphenoidal hypophysectomy involves accessing the pituitary gland through an incision in the upper gingival mucosa, providing direct access to the pituitary gland without external scars. Choices A, B, and C are incorrect because the surgery is not performed through the back of the mouth, the nose, or the sinus channel below the right eye. It is crucial for the client to understand the specific location of the incision to ensure accurate preoperative education and expectations.

Correct Answer: B

Rationale: In this scenario, the priority for the nurse to emphasize in the discharge teaching plan is the 'Guidelines for oxygen use.' As the client with emphysema is being discharged with oxygen therapy, it is crucial for the nurse to ensure that the client understands how to use oxygen properly to prevent complications and promote effective management of the condition. While weight loss, conserving energy, and smoking cessation are important aspects of care for this client, in this specific case, ensuring the safe and appropriate use of supplemental oxygen takes precedence to optimize the client's respiratory function and overall well-being.

Correct Answer: C

Rationale: Increased pulse rate is commonly associated with hyperthyroidism due to the increased metabolic rate. Periorbital edema (Choice A) is more commonly associated with conditions like nephrotic syndrome or heart failure, not hyperthyroidism. Atrophied thyroid gland (Choice B) is not typically an assessment finding for hyperthyroidism as the gland is usually enlarged in this condition. Diarrhea stools (Choice D) can occur in hyperthyroidism, but it is not the most common assessment finding associated with the condition.

Correct Answer: A

Rationale: Sputum culture and sensitivity is the most appropriate diagnostic test for pneumonia as it helps in identifying the causative organism, which is crucial for guiding the selection of the most effective antibiotic therapy. Blood cultures (choice B) are more useful in identifying systemic infections rather than pneumonia specifically. Arterial blood gases (ABG) (choice C) are helpful in assessing oxygenation but do not directly aid in identifying the causative organism. Computerized tomography (CT) of the chest (choice D) is useful for evaluating structural abnormalities in the lungs but is not the initial test of choice for diagnosing pneumonia.

Correct Answer: B

Rationale: Elevated creatinine levels are indicative of dehydration because when the body is dehydrated, the kidneys concentrate urine to preserve fluid, leading to higher levels of creatinine. Low sodium levels (Choice A) can be seen in conditions like hyponatremia but are not specific to dehydration. Low potassium levels (Choice C) are more commonly associated with conditions like hypokalemia. High blood glucose levels (Choice D) are typically seen in diabetes and are not specific indicators of dehydration.
