HESI Medical Surgical Practice Quiz

Correct Answer: B

Rationale: A "shift to the left" in a white blood cell count indicates an increase in band cells, which is typically associated with urosepsis. In this scenario, the nurse should notify the provider and initiate IV antibiotics as a left shift is often seen in severe infections like urosepsis. Requesting a differential analysis on white blood cells would not be the immediate action needed in response to a left shift. Collaborating to strain urine for renal calculi is unrelated to the situation of a left shift in white blood cells due to urosepsis. Assessing for allergic reactions and anaphylactic shock is not the priority as a left shift is not indicative of an allergic response; it is associated with an increase in band cells, not eosinophils.

Correct Answer: A

Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.

Correct Answer: C

Rationale: For a client with a history of calcium phosphate urinary stones, it is essential to limit the intake of foods high in animal protein to prevent the formation of stones. Additionally, reducing sodium intake is crucial as high sodium levels can contribute to stone formation. Therefore, choices A and B are correct. Choice D, which suggests reducing intake of milk and other dairy products, is not specifically recommended for calcium phosphate stones. Clients with calcium phosphate stones should focus on limiting animal protein, sodium, and calcium intake. Choices A and B address these dietary modifications, making them the correct options for this client. Choices D, which is not directly related to calcium phosphate stones, is incorrect.

Correct Answer: B

Rationale: In this scenario, the client's symptoms of dry mouth, constipation, and inability to void are indicative of anticholinergic side effects, which can be caused by medications like propantheline (Pro-Banthine) commonly used to treat incontinence. The first question the nurse should ask is about the client's medications to determine if they are taking anticholinergic drugs. This information is crucial as it can help differentiate between a simple side effect or a potential overdose. Asking about water intake (Choice A) may be relevant later but is not the priority in this situation. Questioning about laxatives or enemas (Choice C) and past occurrences (Choice D) are not as pertinent initially as identifying the client's current medication status.

Correct Answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.
