HESI Medical Surgical Practice Quiz

1. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?

Correct answer: C

Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.

2. A client is receiving continuous ambulatory peritoneal dialysis. Which of the following statements indicates the need for more teaching by the nurse?

Correct answer: D

Rationale: The correct answer is D. Gaining weight is a sign that the client may be retaining fluid, indicating a need for dialysis to remove excess fluid. Skipping dialysis based on weight gain can lead to fluid overload, electrolyte imbalances, and other serious complications. Choices A, B, and C are all correct statements regarding peritoneal dialysis care: taking medications as prescribed is essential for overall health, ensuring the catheter remains in place is crucial to prevent infection, and flushing the catheter with sterile saline daily helps maintain its patency and reduce the risk of infections.

3. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

4. The client is receiving teletherapy radiation for a malignant tumor. Which instruction regarding skin care of the portal site should the nurse provide?

Correct answer: A

Rationale: Protecting the skin from sunlight exposure is crucial to prevent radiation burns and additional skin damage at the treatment site. Sun exposure can exacerbate skin reactions caused by radiation therapy. Applying moisturizing lotions daily may introduce foreign substances or irritants to the treated area, leading to potential complications. Washing the skin inside the radiation portal site is important for maintaining cleanliness and preventing infections. Removing the ink marks after each treatment is unnecessary and may cause unnecessary skin irritation and trauma.

5. A nurse is conducting an assessment of a client who underwent thoracentesis of the right side of the chest 3 hours ago. Which findings does the nurse report to the physician? Select all that apply.

Correct answer: A

Rationale: After thoracentesis, the nurse should assess the client for signs of pneumothorax, which include increased respiratory rate, dyspnea, retractions, unequal chest expansion, diminished breath sounds, and cyanosis. Unequal chest expansion is a key sign of pneumothorax due to the accumulation of air in the pleural space, causing the affected lung to collapse partially. Pulse rate and respiratory rate within normal ranges, like in choices B and C, are not the priority findings to report in this situation. Diminished breath sounds in the right lung could be expected after thoracentesis and may not necessarily indicate a complication like pneumothorax, making choice D less urgent to report.
