HESI Medical Surgical Practice Quiz

Correct Answer: C

Rationale: The correct answer is C. Clients with long-standing diabetes mellitus are at risk for pyelonephritis due to various reasons. Elevated blood glucose levels in diabetes can lead to glucose spilling into the urine, altering the pH and creating a conducive environment for bacterial growth. Neuropathy associated with diabetes can reduce bladder tone and diminish the sensation of bladder fullness, resulting in less frequent voiding and increased risk of stasis and bacterial overgrowth. Increasing fluid intake, particularly water, and voiding regularly can help prevent stasis and microbial overgrowth. Testing urine for ketones and proteins or using tampons instead of sanitary napkins are not effective strategies for preventing pyelonephritis. Keeping the hemoglobin A1c levels below 9% is crucial for managing diabetes, but it alone does not directly prevent pyelonephritis.

Correct Answer: C

Rationale: The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is crucial to assess subtle changes in clients' conditions. Therefore, the registered nurse (RN) who previously cared for this client should be assigned again. Float nurses may lack knowledge of the unit and its clients, potentially leading to oversight of critical details. The licensed practical nurse, while experienced, may not possess the advanced assessment skills and education level of an RN to effectively evaluate and manage pericarditis in this client.

Correct Answer: A

Rationale: The correct answer is A: Drink several quarts of water daily. This advice aims to prevent crystalluria, a potential side effect of sulfonamide drugs. Option B is incorrect because antacids should not be taken with sulfonamides as they can decrease drug absorption. Option C is incorrect as sulfonamides can increase sensitivity to sunlight, not requiring sun exposure limitations but sun protection measures. Option D is incorrect because a sore throat could indicate a more serious adverse effect and should be promptly reported for evaluation.

Correct Answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.

Correct Answer: D

Rationale: A urine specific gravity of 1.040 is higher than the normal range (1.005 to 1.030) and can indicate dehydration, decreased kidney blood flow, or the presence of antidiuretic hormone. In this situation, the priority action should be to increase the client's fluid intake to address the high specific gravity. Obtaining a urine culture, placing the client on restricted fluids, or assessing the creatinine level would not directly address the underlying issue of high urine specific gravity caused by dehydration or other factors.
