HESI Medical Surgical Practice Quiz

Correct Answer: C

Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient's healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.

Correct Answer: A

Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.

Correct Answer: A

Rationale: Choice A, 'I am thrilled that I can continue to eat fast food,' indicates a lack of understanding as fast food is typically high in sodium, which is detrimental for individuals with CKD. The client should be advised to avoid fast food due to its high sodium content. Choices B, C, and D demonstrate a good understanding of the need for sodium restriction in the diet to prevent complications associated with CKD. Cutting out bacon, avoiding salt in cooking, and eliminating high-sodium snacks like potato chips are all positive steps towards managing CKD.

Correct Answer: D

Rationale: Nephrotic syndrome is characterized by glomerular damage, leading to proteinuria (excessive protein in the urine), hypoalbuminemia (low levels of albumin in the blood), and lipiduria (lipids in the urine). These manifestations are key indicators of nephrotic syndrome. Edema, often severe, is also common due to decreased plasma oncotic pressure from hypoalbuminemia. The correct answer is 'All of the above' because all three manifestations are associated with nephrotic syndrome. Dehydration is not a typical finding in nephrotic syndrome as it is more commonly associated with fluid retention and edema. Dysuria is a symptom of cystitis, not nephrotic syndrome. CVA tenderness is more indicative of inflammatory changes in the kidney rather than nephrotic syndrome.

Correct Answer: B

Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.
